Mud Pump

Mud pump refers to the machine that conveys flushing fluid such as mud or water to the borehole during the drilling process. Mud pump is an important part of drilling equipment. In the common positive circulation drilling, the surface flushing medium - clear water, mud or polymer flushing fluid is directly sent to the bottom of the bit through the high-pressure hose, tap and drill string central hole under a certain pressure, in order to cool the bit, remove and transport the cut rock debris to the surface. The common mud pump is piston or plunger type. The crankshaft of the pump is rotated by the power engine. The crankshaft drives the piston or plunger to and fro in the pump cylinder through the cross head. The purpose of pressing and circulating flushing fluids is realized under the alternating action of suction and discharge valves.
