Drilling mud pump is the core equipment for petroleum drilling rig package, and following is the installation procedure of drilling mud pump unit. 1. The drilling pump and the base must be placed on a horizontal basis, the pump should be kept as horizontal as possible, and the horizontal deviation should not exceed 3mm, in order to facilitate the correct distribution of lubricating oil at the power end during operation.   2. The position of the pump should be as low as possible, and the position of the drilling mud tank should be raised as much as possible to facilitate suction.   3. The inner diameter of the suction pipe of the pump shall not be smaller than the inner diameter of the connection part of the pump. Before installation, it is necessary to clean the pump suction and pipelines, the suction line must not have air leakage, valves and elbows should be installed as little as possible, valves must use full-open valves. The length of the inlet pipe should be kept within the length range of 2.1m~3.5m to reduce the friction loss and inertia loss in the suction pipe, which is helpful. For suction, the suction line should be 300mm higher than the bottom of the drilling mud tank.   4. In order to smooth the operation of the pump and extend the life of the wear parts, the drilling pump needs to be equipped with a super charging pump. Between the inlet of the pump and the outlet of the charging pump. There should be a safety valve, which is adjusted to 0.5MPa, which protects the charging pump from damage in the event of overpressure in the suction pipe.   5. The connection between the suction pipe and the drilling mud tank cannot be directly opposite the drilling fluid return point above the drilling fluid pool, so as not to suck the drilling fluid tank bottom debris.   6. Firmly support all suction and discharge lines so that they are not subjected to unnecessary stress and reduce vibrations, which must never be caused by. There is not enough support to allow the line to hang on the pump.   7. In order to prevent damage to the drilling fluid pump due to excessive pressure, the relief valve must be installed at the outlet near the pump, and the safety valve must be installed before any valve, so that if the pump is accidentally started when the valve is closed, and the pump will not be damaged, the relief valve must be installed. The seamless steel pipe for the outlet is led directly to the mud pool, and this seamless steel pipe should have as few turns as possible. If turning, the elbow should be larger than 120°, do not lead the discharge end of the safety valve to the suction pipe of the pump with a pipe, so as to avoid high-pressure drilling fluid drainage when the safety valve is opened out causing unnecessary accidents.

Cylinder liner is one of the main wear parts of drilling mud pump, which is often caused by serious abrasive wear and erosion wear to increase the inner diameter, and gradually form a large gap with the piston, resulting in mud leakage and pump pressure drop. At present, most of the cylinder liners used in oil fields are bimetal cylinder liners, although its inner layer is made of high chromium cast iron with high wear-resistant coating, but the service life is only 400~600 hours, and about 4500 pieces are consumed in Liaohe oilfield alone every year. The potential of expensive high chromium cast iron materials has not been fully realized. In the spirit of increasing revenue and saving expenditure, we have been carrying out trial repair of the scrapped cylinder liner of the 3NB-800 pump since February 1988. For example, its inner diameters of 130 mm and 140 mm were changed to 140 mm and 150 mm respectively. A total of 300 liners have been repaired and tried to be used in the Liaohe oilfield. The trial results show that its life span is as much as 500 hours, This is equivalent to the service life of a new liner, while the repair cost is only 50% of the price of a new liner. At present, there are four kinds of cylinder liners 130, 140, 150 and 160 mm commonly used in Liaohe Oilfield, and there is a high chromium cast iron with a thickness of 6 ~ 8 mm on the inner diameter surface. Usually, after the inner diameter is worn by 0.5~0.8mm, the cylinder liner fails. From this, it is possible to explore the potential of high-chromium cast iron and transform the obsolete cylinder liners into new cylinder liners with a larger inner diameter, as following; 1. Preparation before repair ( 1 ) Carefully select those centrifugally poured high chromium cast iron layers with uniform thickness from the waste cylinder liners, and in the inner diameter reprocessing and reheat treatment, it is possible to meet the requirements of technical conditions as repair objects. ( 2 ) Seal the repaired cylinder liner for cleaning, and use sandpaper or wire brush to remove rust spots and dirt on the inner and outer surfaces. ( 3 ) According to the technical requirements, repair welding is carried out on the defective parts of the outer surface and end of the cylinder liner. 2. Repair procedure There are two types of repair processes, one is to machine after heat treatment, and the other is to machine directly without heat treatment. (A) Method of machining after heat treatment (1) Select 130, 140, 150 mm cylinder liners with a layer thickness of 6~8 mm and place them in the furnace for protection annealing. When annealing, the cylinder liner should be placed upright in the heating furnace, and its stop end should be up. The hardness after annealing should be HRC 30~35. (2) After annealing, the machining process is carried out according to the inner diameter size requirements of the "new cylinder liner", and the grinding amount is left (the usual grinding allowance is 0.4 mm. (3) Protective quenching after machining processing, tempering should be carried out immediately after quenching, and the time of intermediate parking should not exceed 24 hours. The hardness after tempering should reach HRC60~64. (3) The inner diameter of the cylinder liner after tempering is ground and honed to meet the requirements of the drawing. (B) Method of direct machining without heat treatment The cylinder liner that has undergone hardness test of HRC60 or more is directly turned by special tools, and the cutting speed is controlled during procedure: At 10~20 meters per minute, the passing amount is 0.3~0.6 mm per revolution, the cutting depth is 0.5~1.0 mm, and the grinding amount is left. Its inner diameter is finally ground and honed to meet the requirements of the drawing. The cylinder liner repaired by the above method should be painted and oiled after passing the inspection according to the technical requirement, and packaged for later use.

Drilling pumps were formerly known as "mud pumps". If the whole drilling operation process is compared to human life activities, then the drilling pump, like the human heart, is the source of continuous circulation of drilling fluid from the ground to the bottom of the well, and then from the bottom of the well back to the surface. Drilling pumps are an important part of drilling equipment. In commonly used rotary drilling, it is to send the surface washing medium, drilling fluid, under a certain pressure, through the high-pressure hose, swivel and drill string center hole, straight to the bottom of the drill bit, so as to achieve the purpose of cooling the drill bit, removing the cut rock chips and transporting them to the surface. The commonly used drilling pump is piston type or plunger type, the crankshaft of the pump is driven by the power machine, and the crankshaft is driven by the crosshead and then driven by the piston or plunger in the pump cylinder to reciprocate. Under the alternating action of suction valve and discharge valve, the purpose of pressure delivery and circulation of drilling fluid is realized. During the drilling process, if the drilling pump does not work properly, a downhole drilling accident will occur, just like the human heart has stopped beating. The classification of drilling pumps can be divided into single-acting drilling pumps and double-acting drilling pumps according to the form of action, and can be divided into three cylinders and five cylinders according to the number of cylinders.
