Cause Analysis of Internal Gear Pump Pressure and Lift

Internal gear pump parts wear and tear can cause leakage, leakage caused by internal gear pump pressure and flow become smaller. Leakage between the sleeve and the gear end levitates over a large area and thus leaks in the body portion. About 50% to 70% of all this part of the drain leakage. Wear gear pump leakage to reduce volumetric efficiency, pump input power is much lower than the output power. The losses are all converted into heat, which can cause the pump to overheat. If combined with the plate pressure, because there will be a floating sleeve moves a small amount of work caused by wear and tear, resulting in pressure drop flow, such as the floating sleeve must be replaced or repaired.

1, Internal gear pump mainly by the gear, shaft, pump body, pump cover, bearing sleeve, shaft seal and other components. Tight gear and shaft heat treatment, high hardness and wear resistance, with the shaft installed in the sleeve together. Lubrication of all moving parts in the pump is used for its transport.

2, Four bearings in the pump float in the pump body installed automatically adjust the working pressure of the end of the interval size, so the pump pressure stability, low output flow pulsation and high volumetric efficiency.

The internal gear pump is an important part of the intermeshing of the involute gear rolling through a pair of identical parameters and structure, and the low pressure tank can be made to work up to high pressure oil. The mechanical energy of the engine is converted into hydraulic energy to power the device. Gear pump flow, reliability and good. The use of the process prone to wear failure, should pay attention to maintenance.
