Troubleshooting in the operation of high frequency induction hardening machine tools

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

1. The inductor is short-circuited between turns, and the inductor inductance is too large.

2. The circuit board of the equipment is wet.

3. The drive board is broken.

4. The IGBT module is broken.

5. Faults such as transformer ignition cause overcurrent phenomenon.

High frequency induction hardening machine tool overvoltage:

1. The grid voltage is too high (generally, the industrial electricity range is between 360-420V).

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

Problems in the hydraulic pressure of high frequency induction hardening machine tools:

1. The pressure of the water pump is not enough (the shaft wears due to the long-term operation of the water pump).

2. The water pressure gauge is broken.

Problems in the water temperature of high frequency induction hardening machine tools:

1. The water temperature is too high (generally set the temperature to 45 degrees).

2. The cooling water pipe is blocked.

Phase loss of high frequency induction hardening machine:

1. The three-phase incoming line is out of phase.

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

We need to investigate the causes of different failures and solve the problems in order to repair the equipment in time without delaying the work.
