Working principle of drilling mud pump

Shandong Changqing Petroleum Hydraulic Machinery Co., Ltd. shares the working principle of the drilling mud pump: The mud pump is a kind of machinery that transports the washing liquid such as polymer washing liquid, water and mud to the drilling hole during the oil drilling process. . It can drive the drilling, fixing the wall, cleaning the drill, cooling the drill bit, and also bring the drilled drill debris back to the ground. There are two types of common mud pumps, which are plunger type or piston type. The crankshaft of the pump is driven by the power machine. In the pump cylinder, the plunger or piston is reciprocated by the crankshaft through the crosshead. Under the double interaction of the discharge valve and the suction valve, the purpose of circulating flushing and pressure feeding is achieved.
