Mud pump

Mud pump refers to a machine that transports flushing fluids such as mud or water into the borehole during the drilling process. Mud pumps are an important part of drilling equipment. In the commonly used positive circulation drilling, it is to send the surface flushing medium-water, mud or polymer flushing liquid directly to the bottom of the drill bit through the high-pressure hose, the water tap and the center hole of the drill string under a certain pressure to achieve The purpose of cooling the drill bit, removing the cuttings and transporting them to the surface. The commonly used mud pump is of 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 the suction and discharge valves, the purpose of pressurizing and circulating the flushing liquid is realized.

Features of Mud pump:

1. Large flow adjustment range: it has the four-speed flow that can meet the needs of large and small-diameter drilling rigs, the flow adjustment range is large, and the parameter selection is reasonable. It can be used with XY-4 core drilling rig and XY 5 drilling rig. It can meet the needs of core drilling of different diameters, different hole depths and different geological cores.
2. Improve the service life: the piston is a self-sealing S-type polyurethane rubber piston with a bowl-shaped and nylon backrest.
3. Five dustproof sealing rings: There are five dustproof sealing rings on the tie rod to prevent the mud at the hydraulic end from being brought into the power end and the lubricating oil filter at the power end. It has been proved by many production tests that the sealing is reliable and the performance is good. Causes the gear to extend the service life.
4. Reduce impact noise: steel balls are used for the inlet and outlet valves. And there is a sound-absorbing rubber pad on the valve cover to reduce impact noise.
5. Anti-seismic pressure gauge: The pressure gauge adopts BY-1 type anti-seismic pressure gauge, which has a long service life.
6. Compact structure: compact structure and beautiful appearance. Good disassembly, easy maintenance and relocation.
