高周波焼入れ装置 water temperature alarm elimination method

1. After the high-frequency quenching equipment is turned on for a long time, the water temperature alarm phenomenon occurs during the work: check the water temperature of the pool, and if the water temperature of the pool is too high, the water temperature alarm can be changed, and the cooling water can be replaced.

2. When the high-frequency quenching equipment works for a period of time or a few minutes, the water temperature will alarm, and it can continue to work after a period of shutdown. Frequent alarms: Check the cooling water pipe inside the main control cabinet to see if there is any blockage. In the case of long-term use, the cooling water must be guaranteed. It can avoid the water temperature alarm or other equipment failure caused by the debris in the water clogging the water pipe. Water pipe blockage removal method: remove all water pipes from the direction of the water outlet inside the control cabinet, and use an air compressor or other blowing equipment to remove them one by one to ensure that all water pipes are unblocked.

3. After confirming that all the water pipes are unblocked, the equipment still alarms, it is very likely that the equipment is seriously scaled and needs to be descaled. A descaling agent can be purchased in the market for descaling. Descaling method: According to the size of the equipment, about 25 kg of water can be mixed with 1.5-2 kg of descaling agent, and the water pump can be circulated for 30 minutes, then replaced with clean water and circulated for 30 minutes.

4. Sometimes it alarms and sometimes stops: the pressure of the water pump is unstable. If the pressure of the water pump is unstable, air bubbles are easily generated in the water pipe. Because the position of the cooling water box of the three-phase bridge is relatively high, the air bubbles will go up and part of the cooling water box will be empty, so This part is easy to cause the equipment water temperature alarm protection due to the high water temperature. Solution: just increase the pressure of the pump.
