Gear pump internal parts wear will cause internal leakage, gear pump internal leakage caused by pressure and flow become smaller. One of the floating sleeve and the gear surface between the leak area, resulting in the main part of the internal leakage. This part of leakage accounted for 50% of the total internal leakage of about 70%. The wear and tear of the lost circulation gear pump volumetric efficiency decreased, pump output power is much lower than the input power. The loss of all the heat into the heat, it will cause the pump overheating. If the combination of flat compression, due to work floating sleeve will be a small amount of movement caused by wear and tear, resulting in pressure drop, such a floating sleeve must be replaced or repaired. 1 gear pump mainly consists of gear, shaft, pump body, pump cover, bearing sleeve, shaft seal and other components. Gear and shaft are subject to strict heat treatment, high hardness and wear resistance, together with the shaft installed in the sleeve. All moving parts in the pump are lubricated with the medium they supply. 2 pump four bearing sleeve floating installed in the pump body, with the work of pressure automatically adjust the size of the end interval, so the pump pressure stability, small output flow pulsation, volumetric efficiency. | Gear pump is through a pair of parameters and structure of the same involute gear rolling mutual engagement, the tank of low-pressure oil to work can be an important part of high-pressure oil. The mechanical power of the engine into hydraulic power device. Gear pump flow, reliability is good. Its use process prone to wear failure, should pay attention to maintenance.
