Regular maintenance of intermediate frequency quenching equipment
1. Reliable quality, regular maintenance device
Regularly repair the bolts of various parts of the intermediate frequency quenching equipment and the contacts of the tightening contactor relay. If there is looseness or poor contact, repair and replace it in time, and do not use it reluctantly to prevent major accidents.
2. Regularly check whether the wiring of the load is good
The oxide skin accumulated in the diathermy induction coil of the intermediate frequency quenching equipment should be cleaned up in time; cracks in the insulation furnace lining should be replaced in time; the load of the insulation frequency conversion device is located at the work site, and the failure is relatively high, which is often ignored. Maintenance of the load to prevent the failure wave!
3. Regularly remove the dust in the power cabinet
In particular, the outside of the thyristor core of the intermediate frequency quenching equipment should be wiped clean with alcohol. In the diathermic quenching process, the plant is near the intermediate frequency heating equipment such as pickling and phosphating, and there are many corrosive gases, which will affect the intermediate frequency quenching. The components of equipment-related devices play a destructive role, reducing the insulation strength of the device. When there is a lot of dust accumulation, the surface discharge phenomenon of the components often occurs. Therefore, attention must be paid to frequent cleaning of the intermediate frequency quenching equipment to prevent failures!
4. Regularly check whether the water pipe joints are firmly tied
When tap water well water is used as the cooling water source of the intermediate frequency quenching equipment, it is easy to accumulate scale and affect the cooling effect. When the plastic water pipes are aged and cracked, it is recommended to replace them in time. run in summer since
