Mud pumps are machines that transport flushing fluids such as mud or water into boreholes. They mainly refer to mud pumps used in the field of oil drilling and are an important part of drilling equipment.

In commonly used positive circulation drilling, it is to send the surface flushing medium, clear water, mud or polymer flushing fluid, under a certain pressure, directly to the bottom of the drill bit through the high-pressure hose, faucet and the center hole of the drill pipe string to achieve The purpose is to cool the drill bit, remove the cut rock cuttings and transport them to the surface.
Commonly used mud pumps are piston or plunger types. The power machine drives the crankshaft of the pump to rotate. The crankshaft drives the piston or plunger to reciprocate in the pump cylinder through the crosshead. Under the alternating action of the suction and discharge valves, the purpose of pressure feeding and circulating flushing fluid is achieved.
Mud pump cylinder liner, cylinder top liner, cylinder head, tie rod, piston, piston pressure plate, leather bowl, piston seat, piston rod, plunger rod, inlet and drain valve, inlet and drain valve seat, cross head, cross head Sliding sleeves, crosshead pins, crankshafts, connecting rods, connecting rod upper and lower bushings, connecting rod copper sleeves, connecting rod screws and nuts, crown nuts, skeleton oil seals, O-rings, bearings and matching gears, shafts, etc. It is easy to have quality problems.
The easily damaged parts of mud pumps are mainly pump casings, bearings, impellers, etc. Adopting advanced anti-wear measures to increase the service life of wearing parts can reduce project investment and improve production efficiency. At the same time, vulnerable parts should be kept on hand for timely replacement.
