The hot summer and high temperature weather affect the cooling effect of the laser cutting machine chiller to a certain extent. In order to ensure the normal operation of the water chiller in summer, we are now communicating with customers and friends about the relevant matters and maintenance methods that should be paid attention to when the water chiller is used in the summer when the ambient temperature is relatively bad. I hope it can help you.

1. Place the chiller in a place with good ventilation and heat dissipation. Poor heat dissipation will cause the condenser condensation temperature and corresponding condensation pressure to be too high, which will cause the high pressure part of the pressure controller to act, and the compressor overload protection will affect the normal use of customers due to the shutdown of the compressor (note: there should be no large heat source in the space within 2M around the equipment).

2. Observe the pressure gauge. During the normal operation of the water chiller, the high pressure pressure should not be greater than 2.0MPA. If the pressure exceeds this pressure, it indicates that the condenser has poor heat dissipation. The solution is to clean the dust on the condenser fins with high pressure gas, and regularly clean the condenser fins with equipment without pressure gauge; The low pressure pressure should not be less than 0.2MPA. If it is lower than this pressure, it means that the condenser has fluorine leakage or the throttling part is dirty and blocked.

3. Please clean the water tank regularly and change the water frequently. Generally, the purified water is replaced once a month, and the water tank is cleaned at the same time (with detergent) to ensure that the water quality of the chiller is clean. If the water tank is not cleaned for a long time, the evaporator inside the water tank will cause poor cold and heat exchange due to microorganisms, which will affect the cooling effect. (It is recommended that users use light-tight reinforced hose from the water chiller to the chamber)

4. Check whether the water system pressure is normal. The water pressure is normal when it is about 0.3MPA, and the flow alarm output will be caused when it is abnormal. In order to avoid abnormal flow of the water cooler, please regularly check whether the filter element and the filter inside the water tank are dirty and blocked.

5. Pay attention to the monthly maintenance of the water chiller, thoroughly clean the internal pipeline of the equipment once a month, and carefully check whether there is oil stain on the refrigeration pipeline. If there is oil stain and the cooling effect of the equipment is poor, ask professional personnel to check and maintain.
