What are the common circuit faults of valve pressure testing equipment?

Valve pressure test equipment in the long-term use of the process, will inevitably encounter various circuit failures, so what are the main? What's the solution?

1. The pump cannot be started when the equipment is powered on

Check whether the switch button is damaged, the ac contactor is damaged, and the oil pump is stuck

2. The equipment is not powered on

Check whether the three-phase four-wire cable is connected to the power supply and whether the fuse is burnt out

3. Equipment tripping frequently

Check whether the air switch current is too small, whether the cable is in bad contact, whether the equipment is working too long, and whether the thermal protection function is on.

4. The device can be started and the itemized movement will not move

Check whether the switch button is damaged, whether the solenoid valve is energized, whether the overflow valve is stuck

Through the above content, I believe that we have been able to understand the valve pressure test bench common circuit failure.
