The solids control system vacuum degasser is a critical component of the petroleum drilling fluid solids control system, primarily designed to remove harmful gases such as natural gas and hydrogen sulfide (including free and dissolved gases invaded during formation drilling) from drilling fluid (mud). It prevents well blowout risks caused by reduced mud density due to high gas content while restoring mud properties to ensure the safety and efficiency of drilling operations. Ⅰ. Working Principle 1.Creation of Vacuum Environment As a vacuum-type degasser, it uses a vacuum pump to generate a negative pressure environment (below atmospheric pressure) inside the degasser’s vacuum tank. 2.Atomization and Degassing of Drilling Fluid Gas-invaded drilling fluid enters the vacuum tank through the inlet and is atomized into fine droplets via nozzles or distributors. Under negative pressure, gases (e.g., methane, hydrogen sulfide) in the droplets rapidly escape, achieving gas-liquid separation. 3.Gas-Liquid Separation and Discharge Separated gases are extracted by the vacuum pump and safely discharged through exhaust pipelines (connectable to combustion units for treatment if necessary). Degassed drilling fluid returns to the solids control system from the bottom outlet of the tank for continuous recycling. Ⅱ. Main Structure and Components Vacuum Tank：The main container with a negative pressure environment, equipped with internal atomization devices (e.g., nozzles, cyclones). Vacuum Pump：Provides vacuum power, commonly using water-ring or rotary vane vacuum pumps. Gas-Liquid Separator：Further separates trace liquids carried by discharged gases to prevent fluid from entering the vacuum pump. Control System：Monitors parameters such as vacuum pressure and liquid level, automatically adjusting operating conditions. Inlet and Outlet Pipelines：Connect to the drilling fluid circulation system for input of gas-invaded fluid and output of degassed fluid. Ⅲ.

Maintenance Key Points and Fault Troubleshooting Daily Maintenance Vacuum pump: Replace lubricating oil every 500 hours. Atomization device: Inspect nozzle blockage weekly and clean with high-pressure water (use a nozzle cleaning tool with diameter ≤0.3mm). Sealing system: Test airtightness of tank flanges and pipeline interfaces monthly (leakage rate <0.5%/h). Common Faults and Solutions Insufficient vacuum pressure: Caused by pump wear or system leaks. Replace impellers/seals and check for leaks with soapy water. Reduced degassing efficiency: Due to clogged nozzles or high liquid level. Clean nozzles and adjust the inlet valve to maintain liquid level at 2/3 of tank height. Abnormal vibration: Caused by misaligned motor couplings or loose foundation bolts. Re-align couplings and tighten bolts (to ≥90% of specified torque). Liquid carryover in discharged gas: Due to failed gas-liquid separators or low vacuum pressure. Replace separation components and increase vacuum to ≥-0.06MPa. Ⅶ. Collaboration with Other Solids Control Equipment The vacuum degasser typically works with the following equipment to form a complete mud purification process: Shale shaker: First-stage treatment to separate >74μm drill cuttings, reducing solid load on the degasser. Desander/desilter: Processes 20-74μm particles to minimize wear on subsequent centrifuges. Mud Centrifugal Pump: Separates <20μm ultra-fine particles and recovers valuable solids like barite. Mud tanks: Store degassed mud and provide buffer volume (typically 4-6 tanks). Through full-process collaboration, mud sand content can be controlled below 0.5% and gas content below 1%, meeting the requirements of high-complexity drilling operations.    

In the energy extraction sectors such as oil and gas, the solids control system plays a crucial and indispensable role. As an essential piece of equipment within the solids control system, the mud cleaner is of great significance for the purification treatment of drilling mud. I. Main Functions of the Mud Cleaner in the Solids Control System The solids control system mud cleaner is primarily responsible for the fine-grained treatment of drilling mud, further separating and removing solid particles of different sizes. The specific functions are as follows: 1.Desanding When the drilling mud enters the mud cleaner during the treatment process, it first passes through the desanding hydrocyclones. These hydrocyclones utilize centrifugal force to separate relatively large-sized sand particles (typically larger than 74 microns) from the mud. This separation process helps prevent the sand particles from causing abrasion to drilling equipment, such as the mud pump pistons and mud pump liners and the nozzles of drill bits, thereby extending the service life of the equipment. Additionally, it avoids the sedimentation of sand particles in the mud circulation system, which could otherwise affect the normal circulation of the mud. The separated sand particles are discharged from the underflow port of the hydrocyclone, while the mud containing finer particles flows out from the overflow port and enters the desilting hydrocyclones. 2.Desilting The desilting hydrocyclones further process the mud that overflows from the desander hydrocyclones, separating the mud particles with a size ranging from 15 to 74 microns. Removing these mud particles can improve the rheological properties of the mud, reducing its viscosity and shear force, so that it can better meet the technological requirements during the drilling process. For example, it enhances the mud's ability to carry cuttings and its fluidity in the wellbore. Similarly, the underflow of the desilting hydrocyclones discharges the mud particles, and the relatively clean mud that overflows flows to the shale shaker at the bottom. 3.Fine Screening The shale shaker performs the final fine-grained treatment on the mud that overflows from the desander and desilter hydrocyclones. Through the vibrating screening method, the remaining fine particles are separated from the mud, resulting in relatively pure mud. Providing high-quality mud for drilling operations helps improve drilling efficiency and reduces the occurrence of complex downhole situations. Ⅱ. Detailed Introduction to the Mud Cleaner in the Solids Control System The mud cleaner is a key device to ensure the performance of drilling mud and the smooth progress of drilling operations. The following is a detailed introduction to various aspects of it: 1.Structure Vibrating Screen Component Screen Box: As the main supporting structure of the vibrating screen, it is usually welded by high - quality steel, with sufficient strength and stiffness to withstand the impact and vibration of the mud. Its design takes into account the convenience of installation, maintenance, and replacement of internal components. Screen Mesh For Shale Shaker And Mud Cleaner: It is the key component for solid-liquid separation and is generally woven from materials such as stainless steel wire or synthetic fiber. According to the size distribution of solid particles in the drilling mud, screen meshes with different mesh numbers can be selected. The common mesh number ranges from 40 mesh to 325 mesh. Fine - mesh screens are used to separate smaller particles, while coarse - mesh screens are used for the preliminary separation of larger particles. Vibrating Motor: It provides power for the vibrating screen and generates high - frequency vibration through the rotation of the eccentric block. The parameters of the vibrating motor can be adjusted according to the size, weight of the screen box, and the mud treatment capacity to ensure that the screen mesh can generate appropriate vibration intensity and frequency, enabling efficient solid - liquid separation of the mud on the screen mesh. Hydrocyclone Component Feed Pipe: Located at the upper part of the hydrocyclone, the mud enters the hydrocyclone tangentially through the feed pipe at a certain speed and angle, forming a high-speed rotating flow field inside the hydrocyclone. The design of the feed pipe should ensure that the mud can enter the hydrocyclone uniformly and stably, avoiding the occurrence of flow deviation or eddy current. Cylindrical Section: It is one of the main working areas of the hydrocyclone. The mud starts to form a rotating motion in the cylindrical section, and the centrifugal force causes the solid particles to move towards the wall of the hydrocyclone. The diameter and height of the cylindrical section determine the processing capacity and separation effect of the hydrocyclone. Larger diameter and height usually mean higher processing capacity and finer separation ability. Conical Section: Connected below the cylindrical section, its taper is an important parameter affecting the separation performance of the hydrocyclone. As the diameter of the conical section gradually decreases, the rotation speed of the mud gradually increases, and the centrifugal force also increases accordingly, prompting the solid particles to gather towards the wall more effectively and move downward along the wall, and finally be discharged from the underflow port. Overflow Pipe: Located at the center of the top of the hydrocyclone, the cleaned mud after separation forms an inner vortex and is discharged from the overflow pipe. The diameter and length of the overflow pipe will affect the overflow speed and separation effect, and need to be optimized according to the specific properties of the drilling mud and processing requirements. Underflow Pipe: Located at the bottom of the hydrocyclone, it is used to discharge the separated solid particles. The diameter and shape of the underflow pipe will affect the discharge speed of the underflow and the discharge efficiency of the solid particles. It is usually designed in an adjustable form to adjust the flow rate and solid content of the underflow according to the actual situation. Sand Pump Component Pump Casing: Usually made of wear-resistant materials, such as high - chromium cast iron or ceramic composite materials, to resist the wear of solid particles in the mud. The internal structure of the pump casing is designed to guide the mud to flow smoothly into and out of the impeller, reducing hydraulic losses and the generation of eddy currents. Sand Pump Impeller: It is the core component of the sand pump. By rotating at high speed, it generates centrifugal force to transport the mud from the suction end to the discharge end. The shape, size, and number of blades of the impeller are optimized according to the flow rate, head, and mud properties of the sand pump to improve the efficiency and wear-resistance of the pump. Shaft Seal Device: Used to prevent mud leakage, usually in the form of mechanical seal or packing seal. The performance of the shaft seal device directly affects the operational reliability and service life of the sand pump, and regular inspection and maintenance are required to ensure good sealing effect. Drive Motor: Provides power for the sand pump and is connected to the pump shaft through a coupling. The power of the drive motor is selected according to the working requirements of the sand pump to ensure that the sand pump can operate stably under different working conditions and provide sufficient pressure and flow to transport the mud. 2.Functions Efficient Solid - Liquid Separation       First, through the high-frequency vibration of the vibrating screen, the preliminary separation of the larger-sized solid substances from the liquid phase in the mud is realized, and the larger-sized cuttings, sand particles, etc. are intercepted on the screen and discharged. Then, using the centrifugal force of the hydrocyclone, the mud after the preliminary separation by the vibrating screen is further finely separated. The solid particles with smaller particle sizes, such as clay particles and fine sand, are separated from the mud, so that the cleaned mud is discharged from the overflow port, and the solid particles are discharged from the underflow port. Optimization of Mud Properties       Accurately control the solid content in the mud to keep it within a reasonable range to meet the requirements for mud properties in different drilling stages and geological conditions. Improve the rheological properties of the mud, such as reducing the viscosity and shear force of the mud, and improving its fluidity and stability, so that the mud can better carry cuttings, suspend weighting agents, and achieve efficient circulation and transportation during the drilling process. 3.Roles Protection of Drilling Equipment      Removing the solid particles in the mud reduces the abrasiveness of the mud, reduces the wear of drilling pumps, drilling tools, valves and other equipment, extends the service life of these equipment, and reduces the frequency and cost of equipment repair and replacement. Prevent solid particles from accumulating and blocking inside the equipment, ensure the normal operation of the equipment, and reduce the interruption and delay of drilling operations caused by equipment failures. Improvement of Drilling Quality      Clean mud can form a thin and tough mud cake on the wellbore wall, which helps to stabilize the wellbore wall, prevent downhole complex situations such as wellbore collapse and diameter shrinkage, ensure the regularity and stability of the wellbore, and provide good conditions for subsequent drilling, logging, cementing and other operations. The optimized mud properties can improve the rock-breaking efficiency of the drill bit, reduce the balling and wear of the drill bit, make the drilling process smoother, and improve the drilling speed and quality. 4.Importance in Drilling Operations Improvement of Operational Efficiency      The mud cleaner can timely and effectively remove the solid particles in the mud, keep the mud properties stable, enable the mud to better play its roles in carrying cuttings, cooling the drill bit, lubricating the drilling tools, etc. during the drilling process, thereby reducing the number of tripping operations and drilling time, and improving the efficiency of drilling operations. Due to the reduced wear of equipment and the lower failure rate, the continuity of drilling operations is guaranteed, further improving the overall operational efficiency. Reduction of Operational Costs      By extending the service life of drilling equipment, reducing equipment maintenance costs, and lowering the consumption of mud materials (because the mud is recycled, reducing the amount of fresh mud preparation), the mud cleaner can significantly reduce the cost of drilling operations. It reduces the discharge of waste mud, lowers the environmental protection treatment cost, and at the same time meets the environmental protection requirements, avoiding fines and other costs that may be caused by environmental pollution. Ensurance of Operational Safety      Stable mud properties and good wellbore stability reduce the probability of safety accidents such as lost circulation, blowout, and well collapse, ensuring the safety of drilling personnel and the safe operation of equipment. The normal operation of the mud cleaner is one of the key links in the stable operation of the entire solids control system, which is crucial for maintaining the safe and efficient progress of drilling operations. Ⅲ. Summary     The advantages of the mud cleaner are very obvious. Firstly, its compact design makes the equipment occupy a small area and can operate efficiently in a limited space, which is especially suitable for use in places with limited space such as offshore drilling platforms. Secondly, the multi - stage separation working mode can effectively remove solid particles of different sizes in the mud, improve the quality of the mud, thereby extending the service life of the mud and reducing the cost of mud use. In addition, the mud cleaner has a relatively high degree of automation and is easy to operate, capable of achieving continuous and stable operation, reducing the workload and errors of manual operation.      In practical applications, mud cleaners are widely used in onshore drilling, offshore drilling, trenchless engineering and other fields. Whether under complex geological conditions or in operations with high requirements for mud quality, the mud cleaner can play its important role in ensuring the smooth progress of drilling and other projects.      With the continuous development of technology, mud cleaners are also constantly being improved and innovated. New - type mud cleaners have made significant progress in improving separation efficiency, reducing energy consumption, and optimizing the operation interface to meet the ever - changing engineering requirements and environmental protection requirements.

     The shale shaker is a crucial piece of equipment in the oil and gas drilling industry, mainly used for solid control in the drilling fluid system. The following is a detailed introduction: Ⅰ. Structure Screen Box: It is the main part of the shale shaker, usually fabricated from high-strength steel plates. The screen box serves to support the screen mesh and is designed to withstand the vibrations generated during operation. Screens Mesh for Shale Shaker and Mud Cleaner: This is a key component for separating solid particles from the drilling fluid. Screen meshes are available in various materials, such as stainless steel wires and polyurethane. Moreover, different mesh counts of the screen mesh are employed according to the required separation precision. Vibrator: The vibrator is responsible for inducing vibrations in the screen box. It is typically an electric motor equipped with an eccentric block. When the motor rotates, the eccentric block generates a centrifugal force, causing the screen box to vibrate. Feeding Device: It is used to distribute the drilling fluid evenly onto the screen mesh. This ensures that the entire screen surface can be effectively utilized for the separation operation. Underflow Collection System: After the drilling fluid passes through the screen mesh, the liquid portion (underflow) will be collected in a container or channel for further processing. Ⅱ. Working PrincipleThe drilling fluid shale shaker is an essential piece of equipment in oil and gas drilling operations, etc., used for separating solid particles (such as cuttings) from the drilling fluid. Its working principle is mainly based on vibration and screening, as detailed below: Vibration Generation: The shale shaker is usually driven by vibration motors, which are fitted with eccentric blocks. When the vibration motors are powered on and operate, the eccentric blocks rotate at high speed along with the motor shafts. Since the center of gravity of the eccentric blocks deviates from the center of the rotation axis, a centrifugal force is generated during the rotation process. This centrifugal force causes the vibration motors to vibrate, which in turn drives the entire screen box to vibrate. Depending on the configuration and installation method of the vibration motors, the vibration trajectory of the screen box can be categorized into linear, circular, or elliptical. Linear Vibration: When two vibration motors rotate synchronously and in opposite directions, the vibration forces generated by the eccentric blocks cancel each other out in the direction parallel to the motor axes and combine into a resultant force in the direction perpendicular to the motor axes, causing the screen box to move linearly. This linear vibration mode is suitable for the screening of fine-grained materials, enabling the materials to jump linearly on the screen surface, which helps to improve the screening accuracy. Circular Vibration: If there is only one vibration motor or two motors work in a specific coordinated manner, the screen box will generate a circular vibration trajectory. In circular vibration, the materials move in a circular path on the screen surface. This movement pattern has a good effect of lifting and loosening the materials and is suitable for processing coarse-grained materials, offering a relatively large processing capacity. Elliptical Vibration: It combines the characteristics of linear vibration and circular vibration. By adjusting the parameters and installation angles of the vibration motors, the screen box can generate an elliptical vibration trajectory. Elliptical vibration can not only ensure a certain screening accuracy but also provide a relatively large processing capacity, making it suitable for the screening of materials under various working conditions. Material Screening: The drilling fluid containing solid particles (such as cuttings) is evenly conveyed to the surface of the screen mesh through the feeding device. Due to the vibration of the screen box, the drilling fluid on the screen mesh is subjected to the combined action of the vibration force and its own gravity. Smaller particles (including fine solid particles that meet the requirements and the liquid phase) can pass through the mesh holes of the screen mesh and fall into the collection device below the screen box, becoming the undersize product (underflow); while larger solid particles (such as cuttings) cannot pass through the screen mesh, and they keep jumping and moving on the screen surface, gradually moving towards the discharge end of the screen mesh and finally being discharged from the discharge port, becoming the oversize product.      In actual operation, operators can also, based on the properties of the drilling fluid (such as solid phase content, particle size distribution, etc.) and processing requirements, adjust parameters such as the rotation speed of the vibration motors and the angles of the eccentric blocks to change the vibration frequency, amplitude, and vibration trajectory of the screen box, thereby optimizing the screening effect of the shale shaker and improving the processing efficiency and quality of the drilling fluid. Ⅲ. Role in Drilling Operations Removal of Solid Particles: Its primary function is to remove larger solid particles (cuttings) from the drilling fluid. By doing so, it helps to maintain the appropriate properties of the drilling fluid, such as density, viscosity, and fluid loss characteristics. This is of vital importance for the smooth progress of drilling operations. Recycling of Drilling Fluid: After the solid particles are removed, the drilling fluid can be recycled, reducing the cost of replacing the drilling fluid and minimizing the environmental impact. Equipment Protection: By reducing the solid content in the drilling fluid, the shale shaker helps to protect downstream equipment, such as pumps and other solid control devices, from excessive wear and tear.       Selecting a suitable drilling shaker requires comprehensive consideration of multiple factors to ensure that it can meet the needs of drilling operations. The following are some key considerations: Processing Capacity: Determine the processing capacity of the shaker according to the scale of the drilling operation and the expected amount of drilling fluid generated. Generally speaking, a shaker with a larger processing capacity can handle more drilling fluid per unit time. Factors such as the flow rate, density, and solid phase content of the drilling fluid should be taken into account, and a shaker that can effectively handle these parameters should be selected. If the processing capacity is insufficient, it may lead to the overflow of drilling fluid, affecting the operation efficiency and quality. Screening Precision: Select an appropriate screening precision according to the requirements for removing solid particles from the drilling fluid in the drilling operation. Different drilling operations may require screen meshes of different particle sizes to ensure that the unwanted solid particles can be effectively separated. Common screen mesh counts range from dozens to hundreds. The higher the mesh count, the higher the screening precision. For example, in some operations with high requirements for the purity of the drilling fluid, a screen mesh with a high mesh count may need to be selected. Vibration Mode: Common vibration modes of drilling shakers include linear vibration, circular vibration, and elliptical vibration. The linear vibration shaker is suitable for the screening of fine-grained materials and features high screening precision; the circular vibration shaker has a larger processing capacity and is suitable for the screening of coarse-grained materials; the elliptical vibration shaker combines the advantages of linear vibration and circular vibration, offering a better screening effect and processing capacity. Select an appropriate vibration mode according to the actual drilling operation requirements and material characteristics. Screen Mesh Material: The screen mesh is a crucial component of the drilling shaker, and its material directly affects the screening effect and service life. Common screen mesh materials include metal wire woven meshes, polyurethane screen meshes, etc. The metal wire woven mesh has high strength and wear resistance, making it suitable for processing large-particle materials and high-concentration drilling fluid; the polyurethane screen mesh has good elasticity and corrosion resistance, which can effectively prevent materials from blocking the screen holes, improve the screening efficiency, and is suitable for processing fine-grained materials and drilling fluid with strong corrosiveness. Select an appropriate screen mesh material according to the properties of the drilling fluid and material characteristics. Reliability and Durability: Consider the structural design, manufacturing process, and material quality of the shaker, and select products with high reliability and durability. High-quality shakers should be made of high-strength materials and adopt advanced manufacturing processes to ensure long-term stable operation in harsh drilling environments. Check the brand reputation, user reviews, and after-sales service of the equipment, and choose suppliers with a good reputation and a complete after-sales service system to ensure that the equipment can be repaired and supported in a timely manner when a malfunction occurs. Energy Consumption and Maintenance Cost: Select a shaker with relatively low energy consumption to reduce the cost of drilling operations. At the same time, consider the maintenance cost of the equipment, including factors such as the replacement frequency of the screen mesh, the price of spare parts, and their availability. Some shakers have a reasonable design, with convenient screen mesh replacement and strong versatility of spare parts, which can reduce the maintenance cost and downtime. Compatibility with Existing Equipment: Ensure that the selected drilling shaker can be compatible with the existing drilling equipment and solid control system. Consider factors such as the interface size, installation method, and control mode of the shaker to ensure that it can be smoothly integrated into the existing drilling system and achieve efficient collaborative operation. Safety Performance: Check whether the shaker is equipped with necessary safety protection devices, such as protective covers, anti-slip devices, etc., to ensure the safety of operators. Understand the vibration and noise level of the equipment, and select products that meet the safety standards and environmental protection requirements to avoid causing adverse effects on the operators and the surrounding environment.

Screen Mesh Materials      The reasonable selection of the screen mesh material and aperture of the shale shaker is of great significance for ensuring the treatment effect of the drilling fluid, improving the screening efficiency, and extending the service life of the screen mesh. The following is a detailed introduction: 1.Metal Wire Woven Mesh  Material Characteristics: Common types include stainless steel wires (such as 304 and 316 stainless steel), low-carbon steel wires, etc. Stainless steel wires have good corrosion resistance and can adapt to various chemical components that may be present in the drilling fluid, especially suitable for processing corrosive drilling fluid; low-carbon steel wires have high strength and wear resistance and are relatively low in cost.   Application Scenarios: In the processing of large-particle and high-concentration drilling fluid, or in working conditions with high requirements for wear resistance, the metal wire woven mesh performs outstandingly. For example, in some shallow drilling operations or drilling operations in complex geological conditions with larger cutting particles, this screen mesh can withstand greater impact forces and wear. 2.Polyurethane Screen Mesh Material Characteristics: Polyurethane is a polymer synthetic material with excellent elasticity and wear resistance. Its elasticity can effectively prevent materials from blocking the screen holes, and it can maintain a high screening efficiency even when processing viscous drilling fluid. In addition, the polyurethane screen mesh also has good corrosion resistance and can adapt to a variety of chemical environments.  Application Scenarios: It is suitable for processing fine-grained materials and drilling fluid with strong corrosiveness. In deep drilling operations or operations with high requirements for the purification of the drilling fluid, the polyurethane screen mesh can more precisely separate out fine solid phase particles and improve the purity of the drilling fluid. At the same time, due to its good elasticity and wear resistance, its service life is relatively long. 3.Composite Screen Mesh Material Characteristics: It is composed of metal wires and materials such as polyurethane. Usually, the metal wires serve as the framework to provide strength and support, and the polyurethane covers the surface of the metal wires to play the roles of wear resistance and anti-blocking. This composite structure combines the advantages of the strength of the metal wires and the elasticity and wear resistance of the polyurethane. Application Scenarios: It is suitable for various complex drilling working conditions. It can not only process large-particle cuttings but also effectively separate fine solid phase particles. At the same time, it also has good corrosion resistance and anti-blocking performance. In some drilling operations with high requirements for the comprehensive performance of the screen mesh, the composite screen mesh is a good choice. Ⅵ. Screen Mesh Aperture Particle Size of Solid Phase in Drilling Fluid: This is the most important basis for selecting the screen mesh aperture. It is necessary to analyze the particle size distribution of the solid phase particles in the drilling fluid and understand the content of particles of different particle sizes. Generally speaking, the screen mesh aperture should be slightly smaller than the maximum particle size of the solid phase particles to be separated to ensure that these particles can be effectively intercepted. For example, if most of the solid phase particles in the drilling fluid have a particle size between 0.1-0.5mm, then a screen mesh with an aperture of 0.08-0.4mm can be selected to achieve a better screening effect. Drilling Operation Stage: The properties of the drilling fluid and the composition of the solid phase particles will change at different stages of the drilling operation. In the initial stage of drilling, it may mainly be loose materials on the surface of the earth, with larger particles; as the drilling depth increases, the cutting particles will gradually become smaller. Therefore, it is necessary to adjust the screen mesh aperture according to the actual situation at different stages. For example, in the initial stage of drilling, a screen mesh with a larger aperture can be used to quickly remove larger particles; in the later stage of drilling, it can be replaced with a screen mesh with a smaller aperture to further purify the drilling fluid. Performance Requirements of Drilling Fluid: Different drilling operations have different requirements for the performance of the drilling fluid, such as density, viscosity, and sand content. The selection of the screen mesh aperture should help meet these performance requirements. If a lower sand content of the drilling fluid is required, a screen mesh with a smaller aperture needs to be selected to separate out as many solid phase particles as possible; if a higher viscosity of the drilling fluid is required, it may be necessary to appropriately adjust the screen mesh aperture to avoid excessive screening, which may lead to the loss of useful components in the drilling fluid. Ⅶ. Daily Maintenance Techniques 1.Screen Mesh Maintenance Check the Wear Condition of the Screen Mesh: Before starting the equipment each time and during its operation, inspect the surface of the screen mesh for any damage, holes, or severely worn areas. Pay special attention to the edges and fixed parts of the screen mesh, as these areas are prone to damage due to stress concentration. If the screen mesh is found to be severely worn, it should be replaced in a timely manner to avoid affecting the screening effect and the operation of the equipment. Clean the Blockages on the Screen Mesh: The solid-phase particles in the drilling fluid may block the holes of the screen mesh, reducing the screening efficiency. Regularly (such as every few working hours) use a soft brush or a special screen mesh cleaning tool to clean the blockages on the surface of the screen mesh. Avoid using sharp tools to prevent damage to the screen mesh. For highly viscous blockages, the screen mesh can be rinsed with low-pressure water, but be careful not to use excessive pressure, as it may damage the structure of the screen mesh. Adjust the Tension of the Screen Mesh: The tension of the screen mesh has an important impact on the screening effect. A screen mesh that is too loose will cause the materials to slide on the screen surface, affecting the screening efficiency and may also accelerate the wear of the screen mesh; a screen mesh that is too tight may be damaged prematurely due to excessive stress. Regularly check the tension of the screen mesh and adjust it as needed. Generally speaking, the screen mesh should make a clear and crisp sound after being tensioned. 2.Vibration Motor Maintenance  Check the Motor Temperature: During the operation of the equipment, frequently check the temperature of the vibration motor. If the motor temperature is too high, it may be caused by reasons such as excessive load, poor heat dissipation, or motor failure. Once the motor temperature is found to be abnormal, stop the machine immediately for inspection, identify the cause, and deal with it in a timely manner. Tools such as an infrared thermometer can be used to measure the surface temperature of the motor. Lubricate the Motor Bearings: According to the recommendations of the motor manufacturer, regularly lubricate the bearings of the vibration motor. Use appropriate lubricating grease and ensure that the amount of lubricating grease added is appropriate. Too much or too little lubricating grease may affect the service life of the bearings. When adding lubricating grease, pay attention to cleanliness and avoid impurities from entering the bearings. Tighten the Motor Mounting Bolts: The vibration motor will generate vibrations during operation, which may cause the mounting bolts to loosen. Regularly check and tighten the mounting bolts of the motor to prevent the motor from loosening and affecting the normal operation of the equipment and the vibration effect. 3.Screen Box and Other Components Maintenance Check the Connection Parts of the Screen Box: Inspect all the connection parts of the screen box, such as bolts, nuts, and welding points, to ensure that they are firm and reliable. Loose connection parts may cause abnormal vibrations of the screen box and even lead to equipment failures. When loose connection parts are found, tighten them in a timely manner. Clean the Debris Inside the Screen Box: Regularly clean the debris and residual drilling fluid inside the screen box to keep the interior of the screen box clean. The accumulation of debris may affect the vibration effect of the equipment and may also corrode the internal components of the screen box. Check the Vibration Damping Device: The shale shaker is usually equipped with a vibration damping device, such as a vibration damping spring or a rubber shock absorber. Check whether these vibration damping devices are damaged, deformed, or aged. If the vibration damping device fails, it will cause excessive vibrations of the equipment, affecting the stability and service life of the equipment, and it should be replaced in a timely manner. 4.Electrical System Maintenance Check the Electrical Circuits: Regularly inspect the electrical circuits of the equipment for any damage, aging, short circuits, or other problems. Ensure that the connections of the electrical circuits are firm and that there are no loose plugs or sockets. For damaged electrical circuits, replace them in a timely manner to ensure the electrical safety of the equipment. Clean the Electrical Control Box: The dust and debris inside the electrical control box may affect the normal operation of the electrical components. Regularly clean the interior of the control box to keep it dry and clean. Compressed air can be used to blow away the dust, and avoid using a damp cloth to wipe it to prevent short circuits.        By following the above daily maintenance techniques, the service life of the shale shaker can be effectively extended, its work efficiency and reliability can be improved, and the smooth progress of drilling operations can be ensured.
