How to assemble the mud pump spare parts?

HDD mud pumps are critical equipment in drilling operations, and mud pump spare parts are essential to keep them operating efficiently.  How to assemble the mud pump spare parts?

1. The tightening torque for the connection rod bolts is 193~257Nm, and lock washers are installed to prevent the bolts from loosening.

2. All the connection bolts and nuts should be tightened well, no bolt loosing is allowed. 

3. When assembling the suction and discharge valve seats, special attention should be paid for that no foreign material is allowed to exist between valve seat bores and the valve seat surfaces. The valve seat should be fastened well and no bolt is allowed to be loose.

4. When assembling the piston, put the clamping plate above the piston seat, screw the piston seat to use the special piston dismantle tool, put the piston seat into the linking rod so that no rotation can happen, loosen the special piston dismantle tool, and then install the piston according to the sketch (after hand tightening, use the forcing rod to tighten 1 / 4 to 1 / 2 turn). After these, start up the pump and check by hand if the liner surface is too hot; if yes, then please disassemble the liner cover and loosen the thin hex nut for a half-turn, adjust it carefully until it’s no longer over-heating.
