( 5) Vacuum pump noise is too big.

( 6) Vacuum pump oil, we need to maintain and replace the corresponding accessories. In the process of maintenance which problems we should pay attention to?

the reasons of failure.

( 1) Drive motor voltage is not correct or overload.

( 6) Vacuum pump or motor stuck.

solution is as follows:

( 1) Provide the correct voltage for the motor.

( 2) Set the starter motor overload protection of data comparison with data of motor nameplates, be revised if necessary. If the environment temperature is high; The set value according to the normal motor current is increased by 5%.

( 3) Check the fuse.

( 4) Repair or replace the motor. ( By the professional and technical personnel operation)
