Pump Bearing

The important part of the plunger pump is the bearing. If there is play in the bearing, the normal clearance of the three pairs of friction pairs inside the hydraulic pump cannot be guaranteed. At the same time, the thickness of the hydrostatic bearing oil film of each friction pair will be destroyed, reducing the use of the plunger pump bearing. life. According to the information provided by the hydraulic pump manufacturer, the average service life of the bearing is 10000h, and it is necessary to replace the new port if this value is exceeded.

Bearings removed can not be detected without professional testing equipment, and can only be visually inspected. If scratches or discoloration are found on the roller surface, they must be replaced.
