Causes of Common Faults of Mud Pump and Treatment Methods

Mud pump is the key equipment in drilling operation. If mud is compared to blood in drilling operation, mud pump is the heart of blood supply in drilling production. Therefore, its importance in drilling production is self-evident, and the spare parts of mud pump play a certain role in this.

Mud pump is a kind of machine which can transport mud or water to drill hole in the process of drilling. It is an important part of drilling equipment. Its main function is to inject mud into the well with the bit, cool the bit, clean the drilling tool, stabilize the well wall, drive the drilling, and bring the cuttings back to the ground after drilling.

In the normal circulation drilling, the mud pump is to send the surface flushing medium - clear water, mud or polymer flushing liquid under a certain pressure through the high-pressure hose, faucet and the center hole of drill string directly to the bottom of the drill bit, so as to cool the drill bit, remove the cuttings and transport them to the surface. The mud pump is driven by the power machine to rotate the crankshaft of the pump. The crankshaft drives the piston to do reciprocating motion in the pump cylinder through the crosshead. Under the alternating action of the suction and discharge valves, the purpose of pressing and circulating the flushing fluid is realized. Different types of mud pumps are used in different cases to ensure the smooth proceeding of the drilling operation.

Problems in using mud pump:

According to the use of the mud pump, the leakage of the valve box, the burning of the bearing and the abnormal noise are all frequent faults that affect the normal use of the mud pump. Therefore, careful study of the causes of the problem plays a key role in prolonging the service life of the mud pump. At this time, a certain amount of spare parts of the mud pump are needed.

In the process of using the mud pump, the equipment failures caused by specific reasons are different. Reasonable use and maintenance of the equipment can extend the service life of the equipment. At the same time, in strict accordance with the basic elements of normal operation of the drilling pump, "medium power, medium pump pressure, medium speed operation, tight, tight, leak tight, pump pressure does not fluctuate, temperature is normal, sound is normal", the operation can ensure the good operation of the equipment. Of course, it's also important to find the right mud pump spare parts!
