In the industrial production process, materials or equipment will inevitably generate heat, and a refrigeration equipment is required to exchange this part of the heat, take away excess heat, and make the material or equipment produce
at a constant temperature 。 1.
Compressor failure: capacitor burnout, coil winding abnormalities, etc.
; 2.
Water pump failure: caused by poor water quality or foreign matter, AC contactor overload, capacitor burnout, etc.
3.
Refrigeration failure: insufficient refrigerant, compressor failure, throttle orifice failure, condenser dirty blockage and poor heat dissipation effect; 4.
Electronic control failure: high voltage protection relay damp, poor contact or damage, unit electronic board moisture or damage, communication failure, power phase voltage imbalance, power line voltage drop large and other problems 5.
When the compressor fails for some reason, if the water pump continues to run at this time, it may cause the water temperature to rise rapidly, and when the water temperature exceeds 50 degrees, the water pipe and the shaft seal of the pump may cause damage and leakage
.
6.
If it is found that the refrigerator is partially immersed in water, stop running immediately, quickly remove the water in the water tank, and ask a professional to deal with it to avoid the compressor sucking water into the system and causing more serious damage
.
Generally, we first fill the leakage or treatment of the leakage of the refrigerant, and then replace the desiccant, re-vacuum treatment, and fill with the appropriate refrigerant
.
The 10 kW air-cooled chiller will fail due to the harsh working environment, excessive heat load, improper operation and untimely maintenance during the working operation, resulting in low
work efficiency, equipment damage and service life.
Therefore, understanding the common faults of 10 kW air-cooled chillers and doing a good job in the maintenance and repair of 10 kW air-cooled chillers is the daily work content of
users.
