High frequency machine daily maintenance

High frequency machine daily maintenance

Every day before use

• Check that there is sufficient water and cooling agent in the water tank . If needed fill up the water tank.

•Check that there is no water leakage between the inductor handle and the inductor head .

• Check that the isolation is not damaged on the inductor handle .

• Check that the inductor handle or inductor head is not bent or in any other way

damaged .

• Check that the mains cable is not damaged .

Monthly inspection

•Check that the coarse filter by the water tank is not blocked up with dirt . Clean if necessary.

•Check the high-frequency machine transistor, transformer, main circuit, cooling water circuit and ventilation facilities are in good condition or not. Make sure the sensor is in good contact with the transformer.

Quarterly inspection

•Check the time relay, over-current relay, pressure gauge, contacts joints and wiring.

•Check the contacts of the air switch and circuit breaker for ablation.

•Check the relay control system, weak current control system, trigger circuit, etc.

•Check the scale of the cooling waterway and check the flow of the cooling waterway.

•Check whether the protection circuit of the high frequency machine is over-voltage, over-current, insufficient cooling, and high temperature.

• Check if the fuse of the high frequency machine is loose or hot.

•Check if the grounding resistance of the high frequency machine meets the requirements.
