Hydraulic Piston Pump with Bearing Maintenance

Rotary piston pump the most important parts --- bearings, if the bearing clearance, the hydraulic pump can not guarantee that the internal friction to the core three deputy normal gap, but also damage to the friction bearings Hydrostatic Vice film thickness, reduce the service life of piston pump bearings. Hydraulic pump, according to information provided by manufacturing enterprises, the average service life of bearings 10000h, more than this value need to be replaced on the New. Namely, the maintenance of the industry said.
       1) Demolition: The demolition of a dedicated tool bearing down, it is necessary to carry out measurements to check the use of boundaries and the life; no professional testing instruments are unable to detect the bearing clearance and can only be used visual, such as found in the surface roller has scratches or discoloration, it must be replaced.
       2) Detect: In replacement of bearings, the bearings should be noted that the original letters of the alphabet and model, piston pump bearings mostly large load bearing capacity of long life dedicated in principle to buy the original manufacturer, the original specifications of the Products, if the replacement of another brand should consult on the bearings have experienced staff on the look-up table for the purpose is to maintain the accuracy of bearing capacity and load rating.
       3) assembly: using the professional tools for heating bearings, according to the standard factory-assembled components rotating bearing components, in accordance with the standard measurement of the gap size, to reach the standard size of the assembly.
