1. Regularly remove dust from the power cabinet
Especially outside the thyristor die, it should be wiped clean with alcohol. The intermediate frequency power supply generally has a dedicated machine room, but the actual working environment is not ideal. In the melt forging process, the dust is large and the vibration is strong. In the diathermy quenching process, the plant is close to pickling and phosphating equipment, and there are many corrosive gases, which will destroy the components of the induction melting furnace related equipment, and reduce the insulation strength of the device when there is more dust. The surface discharge phenomenon of components often occurs, so it is necessary to pay attention to the frequent cleaning work to prevent malfunctions;
2. Regularly check whether the water pipe joints are firmly tied.
When using tap water as the cooling water source of the induction melting furnace device, it is easy to accumulate scale and affect the cooling effect. When the plastic water pipe ages and cracks, the device should be replaced in time. In the summer operation, the use of tap water well cooling is often prone to condensation, and the circulating water system should be considered. When the condensation is serious, it should be stopped immediately.
3. Regular replacement or cleaning of key components of induction melting furnace related equipment
4, regular maintenance of the device
The bolts of the various parts of the device and the contacts of the tightening contactor relay shall be regularly inspected. If loose or poor contact occurs, they shall be repaired and replaced in time, and shall not be used barely to prevent major accidents.
5. Regularly check whether the wiring of the load is good and whether the insulation is reliable.
The oxide scale accumulated in the heat-transducing induction coil should be cleaned in time; the crack in the insulation furnace should be replaced in time; the melting furnace should be inspected after updating the furnace lining; the load of the insulation variable frequency device is set at the working site, and the fault is relatively high. It is often overlooked. Therefore, strengthening the maintenance of the load and preventing the fault from affecting the variable frequency power supply is an important part of ensuring the normal operation of the device.
