There are many noise problems encountered in the use of vane pumps. Sometimes if there is only a small noise, there may not be a big problem, but if there is a serious noise problem, it must be paid attention. Zhejiang Yongling Hydraulic Machinery Let me explain in detail how we should deal with severe noise.

1. The triangular unloading groove at the oil pressure chamber of the vane pump is too short, resulting in oil trapping and local pressure rise. The chamfer at the top of the blade is too small, and there is a sudden change in the Sichuan force when the blade moves. The tolerance of the blade height dimension is not strictly controlled, resulting in unequal blade height.

2. The curved surface of the stator is severely scratched or worn. The end face of the oil distribution plate is not perpendicular to the inner hole, or the blade is not perpendicular.

3. The oil level of the hydraulic oil pump is too low, the salary is too high, and the oil absorption is not smooth. The suction port is not tightly closed, and air is sucked into the pump.

4. The skeleton oil seal in the end cover of the right pump body is too tight against the drive shaft. The coaxiality between the hydraulic oil pump and the motor is extremely poor. The coupling of the hydraulic oil pump and the motor is improperly installed, which causes shock and vibration during operation.

5. The motor speed is too high or exceeds the rated speed of the hydraulic oil pump. The hydraulic oil pump works under overload pressure.
