Disassemble the lower bearing, only the outer bearing can be selected. If the outer surface of the roller is found to be scratched or discolored, it must be replaced.When replacing bearings, most plunger pump bearings use large load capacity bearings. The original standard products are assumed to be replaced by another brand. People with experience in bearings should be consulted to check the table for replacement. The purpose is to adhere to the bearing and load capacity.

Straight shaft swash plate plunger pumps are divided into two types: pressure oil supply type and self-priming oil type.Most pressure-supplied hydraulic pumps use fuel tanks with air pressure, and some hydraulic pumps have their own sub-pumps to supply pressure to the hydraulic oil inlet.The self-priming hydraulic pump has a strong self-priming ability and does not require external force to supply oil.The hydraulic fuel tank for air pressure oil supply, after each start of the machine, has to wait for the hydraulic fuel tank to reach the use of air pressure before operating the machinery.If the air pressure of the hydraulic fuel tank is insufficient, it will damage the machine, which will cause a pull-off effect on the hydraulic pump and the sliding whip, and it will cause abnormal wear and tear of the return plate and the pressure plate in the pump.The plunger pump used to replenish the oil pump for oil supply is selected. After use, the operator needs to check the plunger pump 1-2 times a day to check whether the hydraulic pump operation dynamics are normal.If you find that the speed of the hydraulic cylinder drops or the car is stuffy, you should check the replenishment oil pump to see if the internal gear pump space is too large. For self-priming oil-type plunger pumps, the oil in the hydraulic tank must not be lower than the lower limit of the oil standard, and the quantity of hydraulic oil must be maintained.The higher the cleanliness of the hydraulic oil, the longer the service life of the hydraulic pump.
2 Bearings for hydraulic pumps
The main component of the plunger pump is the bearing. Assuming that the bearing has clearance, the normal vacancy of the three pairs of friction pairs in the hydraulic pump cannot be made. Together, the thickness of the hydrostatic support oil film of each friction pair will be damaged, and the service life of the plunger pump bearing will be reduced.
