What are the causes of fracture and damage to the vane pump shaft of a hydraulic press?

In the daily work of the machine, many problems will be found. Among them, there are many reasons for the fracture and damage of the vane pump shaft of the hydraulic press. Among the more common reasons are the following. Today I will share with you some popular science. I hope it will be helpful to you. help.

1、the quality of the material of the hydraulic press vane pump shaft itself, and poor heat treatment, can easily cause the pump to break. Therefore, when purchasing a hydraulic press, you should pay attention to the material quality of the pump shaft.

2、if dirt enters the vane pump of the hydraulic press, it will get stuck between the relative motion sliding surfaces of the rotor, stator, rotor male oil distribution plate, etc., causing the pump shaft to transmit excessive torque and break. Therefore, pollutants should be prevented from entering the pump.

3、because the motor shaft and the vane pump shaft are not concentric, it is easy to cause breakage during operation. After the pump shaft breaks, it must be replaced in time, but the cause of the broken shaft must be found out, otherwise the same mistake will be repeated.

4、the pump shaft breaks due to severe overloading of the vane pump. Abnormal high pressure is generated due to malfunctioning systems such as the relief valve. If there are no other safety protection measures, the pump shaft breaks due to severe overloading. This should be taken seriously.

The above reasons can easily cause the pump shaft of the hydraulic press to break. In order to prevent the pump shaft from breaking, the vane pump should be inspected and maintained.
