Mud pump refers to a machine that transports flushing fluid such as mud or water into the borehole during drilling. Mud pump is an important part of drilling equipment. In the common positive circulation drilling, it is the surface flushing medium-clean water, mud or polymer flushing fluid under a certain pressure, through the high-pressure hose, faucet and the center hole of the drill string directly to the bottom of the drill bit to achieve The purpose of cooling the drill bit, removing the cutting debris and transporting it to the surface. Commonly used mud pumps are 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. Under the alternate action of suction and discharge valves, the purpose of pressure delivery and circulation of flushing liquid is realized.
