2. Turn the vacuum pump over and replace any two-phase wires of the 380V three-phase

3. Replace the electric contact vacuum gauge

4. Check the control system and replace the broken parts

5. Whether the emergency stop switch is pressed, whether the power supply’s positive and negative connection is wrong, whether the air pressure is normal. If the equipment with inflation function, check whether the air compressor and inflation tube are inserted incorrectly.
6. Adjust the position of the travel switch or replace the travel switch.


三.Keeps vacuuming

Several reasons for the failure:
1. The vacuum pump AC contactor or vacuum gauge is broken
2. The control system is broken

The corresponding solution:
1. Replace AC contactor or vacuum gauge
2. Overhaul or replace the control system circuit board
