The DVE vacuum pump motor will have overcurrent phenomenon after overheating. If the motor power is not unplugged in time, it is likely to cause the motor to burn out. So how to solve the phenomenon of DVE vacuum pump motor overheating?

The power and speed are matched with the DVE vacuum pump and cannot be changed. The fan is installed on the main shaft of the motor. The speed of the motor determines the speed of the fan and cannot be replaced. Although increasing the number of fan blades can play a certain role, after the increase in the number of blades, the dynamic balance is not easy to find. If the alignment is not good, it will cause the vibration of the motor to increase.

(1) Lengthen the original fan cover by 40cm, and install an axial fan with the same diameter as the fan cover. The motor power of the axial fan is 850W, the speed is 1489r/min, and the voltage is 380V. The original fan is kept. There is another power control for the axial flow fan, and there is no interlock between the axial flow fan and the main motor. After the DVE vacuum pump is started, the axial flow fan is started in time, and the axial flow fan is stopped 30 minutes after the DVE vacuum pump is shut down, so that the main motor can be fully cooled.
(2) Regularly remove dust on the motor, keep the motor heat sink clean, and increase its heat dissipation capacity.
(3) Adjust the voltage of the bus bar where the DVE vacuum pump is located to 400V.
