Background technique

The mud pump is a machine that transports flushing fluid such as mud or water to the borehole during the drilling process. It is an important part of the drilling machinery and equipment. The role of cooling the drill bit, cleaning the drilling tool, fixing the well wall, driving the drilling, and bringing the cuttings back to the ground after drilling. In the commonly used positive circulation drilling, the mud pump is to flush the surface with water, mud or polymer. Under a certain pressure, the flushing fluid is sent directly to the bottom end of the drill bit through the high-pressure hose, the faucet and the center hole of the drill string, so as to cool the drill bit, remove the cut cuttings and transport them to the surface. The commonly used mud pump is Piston type or plunger type, the crankshaft of the pump is driven by the power machine to rotate, and the crankshaft drives the piston or plunger to reciprocate in the pump cylinder through the crosshead, and realizes pressure feeding and circular flushing under the alternate action of the suction and discharge valves For the purpose of liquid, during the reciprocating working movement of the piston rod, more debris and external impurities may also enter the cylinder body, causing greater wear and tear on the cylinder body, and it needs to be cleaned regularly. However, the current The cleaning of the mud pump is more complicated, which is not conducive to the long-term work of the mud pump.
