Disassemble the lower bearing and select it for testing. If scratches or discoloration are found on the surface of the roller, replace it. When replacing the bearing,hydraulic pump the English letters and type of the bearing should be kept. Most plunger pump bearings use large load capacity bearings. Purchase the original manufacturer and the original standard product. If you replace another brand, you should consult a person with experience in bearings The purpose of table exchange is to maintain bearing and load capacity.
Hydraulic plug pump application and repair methods: This article focuses on the straight-axis swash plate plunger pump,hydraulic pump and introduces the use and repair methods of hydraulic pump plug pumps. The oil supply method of the hydraulic pump: The straight shaft swash plate plunger pump is divided into two types: pressure supply type and self-priming type. Most of the pressure-supply hydraulic pumps use a pneumatic tank, and some hydraulic pumps have their own supplementary sub-pumps to supply pressure oil to the oil inlet of the hydraulic pump. The self-priming hydraulic pump is very talented in self-priming,hydraulic pump and there is no external force to supply oil.
The hydraulic oil tank with pneumatic oil supply can only operate the machine after the hydraulic tank reaches the applied air pressure every time the machine is started. For example, when the air pressure of the hydraulic oil tank is lacking, it will act as a machine,hydraulic pump which will cause a pull-off scene of the sliding whip in the hydraulic pump,hydraulic pump and cause abnormal wear of the return plate and pressure plate in the pump. Choose a plunger pump supplied by a charge pump. After use,hydraulic pump the operator needs to check the plunger pump 1-2 times a day to check whether the hydraulic pump is working properly. If it is found that the speed of the hydraulic cylinder is slowing down or the car is stuffy,hydraulic pump the charge pump should be broken to check whether the empty space of the internal gear pump is too large.
Bearings for hydraulic pumps: the component of the plunger pump is the bearing. Assuming that the bearing has clearance,hydraulic pump the normal vacancy of the three pairs of friction pairs of the hydraulic pump cannot be made. At the same time,hydraulic pump the thickness of the hydrostatic support oil film of each friction pair will be damaged and the plunger pump will be lowered. The service life of the bearing. According to the information provided by the hydraulic pump manufacturer,hydraulic pump the average service life of the bearing is 10000h. The disassembled bearing cannot be inspected without checking the instrument. You can only choose to measure it. If the roller is found to be discolored or discolored, it will be replaced.
