Bearing For Hydraulic Pump
The most important component of plunger pump is the bearing. If the bearing has a clearance, the normal clearance of three pairs of friction pairs in the hydraulic pump cannot be guaranteed. At the same time, the thickness of oil film in the static hydraulic support of each friction pair will be damaged, and the service life of the piston pump bearing will be reduced. According to the information provided by the hydraulic pump manufacturer, the average service life of the bearing is 10000h, beyond which a new opening is required.
Disassembled bearing, without professional testing equipment, can not detect the bearing clearance, can only use visual measurement, if the roller surface is found to have scratches or discoloration, must be replaced.
When replacing bearings, attention should be paid to the English letters and models of the original bearings. Most of the piston pump bearings adopt high-load bearing capacity. It is better to buy the products of the original manufacturer and specifications.
