Heat pump oil pump body back plate and platen wear huge

June 16, 2022
Heat pump oil pump body back plate and plate wear are abnormal wear and tear. The efficiency of the hydraulic system depends on the volumetric efficiency of the HTF. When the volumetric efficiency drops to 72%, routine maintenance needs to be stopped, the bearing and aged seals modified, the friction pair beyond the mating clearance restored, and the performance restored. Straight shaft swash plate piston pump is divided into two types of self-suction oil pressure type. Most of the pressure supply type hydraulic pump with air pressure tank, there are hydraulic pump itself with a charge pump to the hydraulic pump inlet to provide pressure oil. Self-priming oil pump self-priming can be very strong, no external oil supply. Hydraulic pressure oil tank, after each start the machine, must wait for the hydraulic pressure box to reach the use of pressure, the ability to operate machinery. Such as the lack of pressure when the hydraulic tank as a machine, the hydraulic pump will slip with the whip to form a pull-off phenomenon, the formation of heat transfer oil pump body back plate and plate abnormal wear and tear. The use of oil pump piston pump, the use of 3000h, the operator needs to check the piston pump 1-2 times a day to check the hydraulic pump running sound is normal. If you find that the hydraulic cylinder speed or boring car, you should check the charge pump collapse, check the edge of the impeller can scratch, internal gear pump clearance can be too large.
