It is suitable for ordinary drilling working environment with working pressure below 20Mpa and working temperature not higher than 120℃.

Piston assembly is one of the main parts of the hydraulic end system of the mud pump, and also one of the wearing parts in drilling work.

Use elastic sealing material and small actuator thrust to obtain air bubble tight seal, compress the valve seat sealing stress to elastically deform the material

The detachable surface parts in the valve are used to support the fully closed position of the valve core and form the sealing pair.

There are several types of common mud pump cylinder liners: single metal cylinder liner, bimetallic cylinder liner, ceramic cylinder liner, and nickel-based alloy cylinder liner.

The piston rod is processed by rolling, thereby improving the corrosion resistance of the surface and delaying the generation or expansion of fatigue cracks

The mud pump is the "heart" of the oilfield drilling system, and the mud pump cylinder liner is an important and easily worn part of the hydraulic end of the mud pump.

The function of the piston rod is to connect the piston and the crosshead, transmit the force acting on the piston and drive the piston to move.

Piston components include: pistons, piston rings, support rings, piston rods, etc. According to different structural forms

The piston rod is the connecting part that supports the work of the piston. Most of them are used in the oil cylinder and the cylinder motion execution part.

Check before starting: all connection parts should be tightened; the electric rotation direction should be correct; the clutch is flexible and reliable

During the construction, the continuous and normal work of the machinery and the mud pump can make the mud pump exert the highest working efficiency.
