The motor power and speed are matched with the imported 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, but the dynamic balance is not easy to find after the number of blades is increased. If the alignment is not good, the motor vibration will increase.
(1) The fan cover of the original vacuum pump was lengthened by 40cm, and an axial fan with the same diameter as the fan cover was installed inside. The motor power of the axial fan was 850W, the speed was 1489r / min, and the voltage was 380V. The original fan remains. The axial flow fan is equipped with another power supply control, and the axial flow fan is not interlocked with the main motor. Start the axial flow fan in time after starting the imported vacuum pump, and stop the axial flow fan 30 minutes after the vacuum pump stops, so as to make the main motor fully cooled.
(2) Regularly remove the dust on the vacuum pump motor, keep the motor heat sink clean and increase its heat dissipation capacity.
(3) Adjust the bus voltage of the imported vacuum pump to 400V.
