Reasons and treatment of oil leakage of high pressure Parker hydraulic pump

Oil leakage of high pressure Parker hydraulic pump mainly has the following elements:
(1) The external oil pipe of the pump is loose, the pipe joint is damaged, and the gasket is aged or cracked. (2) Cast iron pump casing has blisters or poor welding. (3) If the internal leakage is too large, the pressure at the oil seal will increase and the oil seal will be damaged or flushed out. (4) The oil drain pipe is too long to cause oil leakage at the seal. (5) Variable scheduling arrangement bolts are loose and seals are broken.

The most common defect treatment of the high-pressure Parker hydraulic pump: The output flow of the Sao hydraulic pump is lacking or does not output oil (1) The leakage is too large. The main factor is that the pump has a large empty space and poor sealing. For example, the oil distribution plate is scratched by metal fragments, iron filings, etc.; the sealing surface of the one-way valve in the variable arrangement is not well coordinated, and the bearing surface of the pump body and the oil distribution plate has blisters. The damaged parts of the high-pressure Parker hydraulic pump can be distinguished by looking at the thick and turbid foreign matter in the hydraulic oil in the pump body.
(2) Lack of intake. The factor is excessive resistance on the suction line or lack of oil supplement. If the speed of the high-pressure Parker hydraulic pump is too high, the liquid level in the oil tank is too low, and the oil inlet pipe leaks. (3) The tilt angle of the swash plate is too small and the pump displacement is small. At this time, it is necessary to dispatch the variable piston and add the tilt angle of the swash plate.

There are many types of high-pressure pumps, and Parker hydraulic pumps are an exceptionally contrasting type. This is because it is different from other pumps due to its unique characteristics. Parker hydraulic pump is a pump that directly converts electromagnetic energy into heat energy and mechanical energy. After energization, an alternating electromagnetic field is generated in the pump, the stator and rotor (impeller), and then the force and heat generated are integrated with the motor, pump and boiler. Because in a contact body, the pump can effectively use heat energy and work, generate mechanical energy, and complete the electromagnetic energy conversion.
