Diesel pump assembly should pay attention to several points

Diesel pumps are generally installed in the reverse order of disassembly. Assembly quality is good or bad directly affect the normal operation of the pump, and affect the life of diesel pumps and performance parameters. Assembly should pay attention to the following points:

1, should protect the parts processing precision and surface roughness, do not allow bumps, scratches and other phenomena for the sealing molybdenum disulfide should be clean, tighten the screws and bolts should force uniform;

Diesel pump assembly should pay attention to several points

2, the outlet of the impeller and guide vane inlet flow of the neutral is based on the axial size of the parts to ensure that the flow of a direct impact on the quality of the pump performance, so the size of the diesel pump can not be adjusted;

3, After the diesel pump is assembled, before turning on the filler, turn the pump rotor by hand to check whether the rotor is flexible in the diesel pump or not, and whether the axial run-in is up to the required level.

4, after passing the inspection packing, and pay attention to the filler ring in the relative position of the packing chamber.
