High-frequency induction hardening machine tool overcurrent: There are several situations for general overcurrent:

1. Short circuit between turns of the inductor and excessive inductance of the inductor.

2. The circuit board of the equipment is wet.

3. The driver board is broken.

4. The IGBT module is broken.

5. Overcurrent phenomena caused by faults such as transformer ignition.

Overpressure of high frequency induction hardening machine tool:

1. The grid voltage is too high (general industrial power range is between 360-420V).

2. The circuit board of the equipment is broken (the Zener diode needs to be replaced).

The hydraulic pressure of high-frequency induction hardening machine tools:

1. Insufficient water pump pressure (shaft wear caused by long-time operation of the water pump).

2. The water pressure gauge is broken.

Water temperature problems of high-frequency induction hardening machine tools:

1. The water temperature is too high (generally set a temperature of 45 degrees).

2. The cooling water pipe is blocked.

Phase lack of high frequency induction hardening machine tool:

1. The three-phase incoming line lacks phase.

2. The lack of phase protection circuit board is broken.

We need to investigate different causes of failures and solve problems in response to problems, so that the equipment can be repaired in time without delaying work.
