The use of a Vane Pumps is a delicate activity. A single mistake will cause the whole pump to be unusable or malfunction in use, resulting in damage to the pump parts and shortening the overall service life.

First of all, pay attention to the installation method of the vane pump.

If the coupling is too tight, due to the small or no gap between the coupling and the shaft, the bearing will be injured when it is struck hard, causing early damage to the bearing and affecting the life of the entire pump core. The shaft head is stressed, and the coupling does not reserve a certain amount of axial clearance during installation. Hardware installation will damage the bearing and the bearing retaining ring, and in severe cases, it will damage the entire pump core. Coaxiality. The coaxiality exceeds the specified value of the pump during installation, which will cause the bearing and the entire pump core to be eccentric and early damage. Generally, it is better to control it to less than or equal to about 0.1 mm.

Second, ensure the internal environment of the vane pump.

Because the fuel tank is not sealed, the surrounding dust and iron mixed into the oil can damage the oil pump early. As the cooling device is not installed, the oil temperature will continue to rise during continuous use of the machine. If the oil temperature exceeds 70 degrees for a long time, the life of the oil pump will be greatly shortened, and it will generally be damaged in half a year to a year. In a water-cooled device, due to the poor sealing of the water pipe, water enters the oil, causing the pump core parts to rust, lock, and the blades cannot be thrown out.

Finally, pay attention to the correct direction of the rotating oil port of the vane pump.

The pump core Xiaozi did not enter the hole. This is because the space of the oil pump suction port is reduced, and the oil suction is blocked. The oil suction is not smooth. The performance is: excessive noise, pressure swing, long-term use will cause the oil temperature to rise too fast, and the inner curve of the stator will impact The life is shortened after being corrugated. When rotating, the sealing ring is trimmed or the screws are not evenly tightened to cause Oil Pumps leakage.
