How To Eliminate The Cause Of Hydraulic Pumps Failure




Cause of failure 1 The oil pump is leaking, and the sealing ring is aging;

Remedy: Replace the seal

Cause 2: The end face of the oil pump or the end faces of the main and driven gear bushes are worn or scratched, and the unevenness of the end faces of the two bushes is extremely poor

Remedy: Replace the worn gear oil pump or oil pump shaft sleeve. When the wear is slight, smooth the end surface on the flat plate. The allowable error of its unevenness is 0.03mm; the end face of the upper sleeve is lower than the pump body, and the upper plane (normal value is less than 2.5 ~ 2.6mm). Should be installed on the rear sleeve.

Failure cause 3: internal leakage caused by incorrect assembly of internal parts of the hydraulic pump

Remedy: The unloading piece and seal ring must be installed in the oil chamber so that the two shaft sleeves can maintain balance. The elasticity of the guide wire should be able to twist the upper and lower shaft sleeves toward the driven gear at the same time by a slight angle, so that the machining planes of the two shaft sleeves of the main and driven gears closely fit; the unloading groove on the shaft sleeve must be equipped with a low-pressure cavity. Side to eliminate the harmful dead volume when the gear meshes; before pressing into the self-tightening oil seal, it should be coated with a layer of lubricant.

Point the oil blocking edge toward the front cover, and do not install it in reverse; before installing the pump cover, pour a small amount of hydraulic oil into the pump casing and turn the meshing gear by hand

Cause 4: The hydraulic oil is too dirty

Remedy: Clean the system and replace the hydraulic oil.

Cause 5: The filter of the hydraulic pump is blocked by dirt and cannot function as oil filter

Remedy: Remove dirt from the filter with clean cleaning oil.

Cause 6: Insufficient oil level, suction position is too high, the suction pipe is exposed to the oil surface

Remedy: Add oil to the oil level and lower the oil suction position.
