Mud Pump Piston
The mud pump piston is one of the main parts of the fluid end system of the mud pump, and also one of the vulnerable parts in drilling work. The discharge pressure of mud pump is produced through the reciprocating rectilinear motion of the piston assembly in the piston. The piston assembly is composed of a piston core, rubber, spring, pressing plate, etc..
Mud pump piston and cylinder liner constitute a pair of dynamic sealing and sealing components are assembled on the piston (some mud pump pistons don’t have cylinder liner and are directly linked to the inner wall of the cylinder body). The reciprocating motion of the piston alternately changes the volume of the working chamber and the pump suck and discharge the liquid through the valve.
Therefore, the mud pump piston have the following properties:
(1) Good sealing;
(2) Sufficient strength and stiffness;
(3) The piston body should be firmly positioned and connected to the piston rod, the piston ring, and other parts.
