1. The original fan cover extended 40cm, in which the installation of a fan cover with the diameter of axial flow fan, axial fan motor power 850W, speed 1489r/min, voltage 380V. Fans continue to retain the original. The axial flow fan is additionally provided with a power supply control, and the axial flow fan and the main motor are not provided with a chain. After the vacuum pump is started, the axial flow fan is started to run in time, and the vacuum pump stops the 30min to stop the axial flow fan, so that the main motor is fully cooled;
2. Clean the dust on the motor regularly, keep the heat sink clean, and increase the heat dissipation capacity;
3. The vacuum pump is located in the bus voltage is adjusted to 400V.
