Precautions for laser cutting machine water-cooled machine

1. Compressor overload warning light alarm. Poor heat dissipation can cause the condensation temperature and corresponding condensation pressure of the condenser to be too high, causing the high-pressure part of the pressure controller to operate and the compressor to overload protection. The shutdown of the compressor can affect the normal use of the customer. The chiller should be placed in a location with good ventilation and heat dissipation.

2. The pressure gauge is abnormal. When the chiller is operating normally, the high-pressure pressure should not exceed 2.0MPA. If this pressure is exceeded, it indicates poor heat dissipation of the condenser. The solution is to clean the dust on the condenser heat sink with high-pressure gas, and regularly clean the condenser heat sink without a pressure gauge; The low-pressure pressure should not be less than 0.2MPA. If it is lower than this pressure, it indicates that the condenser is leaking fluorine or the throttling part is dirty and blocked.

3. The cooling effect has decreased. If the water tank is not cleaned for a long time, the evaporator inside the water tank will produce microorganisms, which will lead to poor cold and heat exchange and affect the refrigeration effect. Customers are requested to regularly clean the water tank and frequently change the water. Generally, pure water should be replaced once a month, and the water tank should be cleaned at the same time (using detergent) to ensure that the water quality of the chiller is clean.

4. Water pressure alarm. When the water pressure is around 0.3MPA, it is in a normal state. If it is abnormal, it will cause a flow alarm output. To avoid abnormal flow rate of the chiller, please regularly check whether the filter element and the internal filter of the water tank are dirty or blocked.
