Troubleshooting method for high frequency induction hardening machine tools

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 water pump pressure is not enough (the shaft wears caused by the pump working for a long time).

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.
