High frequency annealing equipment maintenance tips

Compared with resistance furnaces and mesh belt furnaces, high-frequency annealing equipment has many advantages such as power saving, noise-free and convenient adjustment. However, due to the weak overload capacity of semiconductor devices, reasonable use, correct operation and careful maintenance are the key to high-frequency annealing. An important guarantee for the safe operation of equipment and avoiding failures. It is particularly important to maintain the equipment on a continuously running production line. The following editor will tell you about maintenance knowledge.

1. Regularly remove the dust accumulated in the power supply cabinet, especially the outside of the tube core, and wipe it clean with alcohol. Frequency conversion devices in operation generally have dedicated machine rooms, but the actual working environment is not ideal. During the smelting and forging process, there is a lot of dust and strong vibrations. ; In the diathermy quenching process, the device is often close to pickling, phosphating and other operating equipment, and there are many corrosive gases, which will damage the components of the device and reduce the insulation strength of the device. When there is a lot of dust, it often occurs There is a discharge phenomenon on the surface of the component, so you must pay attention to regular cleaning work to prevent malfunctions.

2. Regularly check whether the water pipe joints are firmly tied. When tap well water is used as the cooling water source of the device, scale is easy to accumulate, which affects the cooling effect. When the plastic water pipe ages and cracks occur, the device should be replaced in time. Condensation is likely to occur when using tap well water for cooling during summer operation. You should consider using a circulating water system. When condensation is severe, operation should be stopped.

3. Regularly inspect the device, check and tighten the bolts and nuts of each part of the device. If the contacts of the contactor relay are loose or have poor contact, they should be repaired and replaced in time. Do not use it without force to prevent greater accidents.

4. The accumulated oxide scale in the diathermic induction coil must be cleaned in time; when the insulation furnace lining has cracks, it must be replaced in time; after replacing the new furnace lining of the smelting furnace, attention should be paid to checking that the load of the insulation frequency conversion device is located at the work site, and the fault comparison High, but often ignored. Therefore, strengthening the maintenance of the load and preventing faults from affecting the variable frequency power supply is an important part of ensuring the normal operation of the device.

5. Regularly check whether the load wiring is in good condition and whether the insulation is reliable.

6. When the cooling water quality is poor, key components of the equipment need to be replaced or cleaned regularly. For example, if there is a lot of scale in the cooling water jacket, the cooling effect will be poor and the equipment will be easily damaged.
