The high temperature alarm of the water chiller of the metal laser cutting machine will also occur frequently in hot summer weather. The alarm will only be caused because the water chiller has poor heat dissipation or insufficient cooling capacity. Self-made water chillers generally do not have the problem of insufficient cooling capacity. Generally, the radiator is too dirty and the ventilation is poor, which causes the alarm. Generally, the cooling capacity of small water chillers is not enough. The problem can be solved by increasing the temperature difference and the alarm temperature appropriately.

1) If the power supply system is abnormal and the power supply is low, it is easy to cause the alarm of the water cooler. It is necessary to ensure that the power supply voltage is normal.

2) The water in the chiller is too small, so it needs to be filled with purified water.

3) The water pipe is blocked, the water protection is blocked, and the increase of water flow resistance will also cause an alarm. At this time, it is necessary to do some cleaning and sorting work.

4) If the water temperature is too high, it will cause an alarm. Change the water in time.

5) There is a problem with the water outlet pump in the chiller.

The water chiller is the cooling system of the metal laser cutting machine, which can ensure that the cavity mirror will not be deformed or damaged due to heating, the resonator and resonator frame will not be deformed due to heating, the working gas can work normally, and the high-pressure system can work normally. In order to cooperate with the laser, the chiller will also have corresponding alarm protection box alarm output.
