Mud pump refers to a machine that transports mud or water and other flushing fluid into the borehole during drilling. Mud pumps are an important part of drilling equipment.
In the commonly used positive circulation drilling, it is to send the surface flushing medium—clear water, mud or polymer rinsing liquid to the bottom end of the drill bit through a high-pressure hose, faucet and drill rod center hole under a certain pressure. Cool the drill bit, remove the cut debris and transport it to the surface.
The commonly used mud pump is a piston type or a plunger type, and the crankshaft of the pump is driven by the power machine, and the crankshaft passes the crosshead to drive the piston or the plunger to reciprocate in the pump cylinder. Under the alternating action of the suction and discharge valves, the purpose of pumping and circulating the flushing liquid is achieved.
1.Divided into by action
Single-acting mud pump: only one suction and drainage action is completed in one cycle of piston reciprocation
Double-acting mud pump: completes two suction and drainage actions in one cycle of piston reciprocation
2.According to the number of cylinders of the pump, there are five types: single cylinder, double cylinder, three cylinder, and five cylinders.
