How much do you know about the maintenance of water-cooled chillers?
During normal operation of water-cooled chillers, it is inevitable that dirt or other impurities will affect the cooling effect. Therefore, in order to prolong the service life of the main engine unit and achieve a better cooling effect, regular maintenance and maintenance work should be done to ensure the operating quality of the chiller and improve production efficiency. In order to facilitate new and old users to learn more about the maintenance items of water-cooled chillers, the details are as follows:
1. Check whether the cooling water system of the chiller is normal, whether the cooling tower fan and sprinkler shaft are running well, and whether the water supply of the built-in water tank of the chiller is normal.
2. The system should be cleaned when the chiller is used for six months, and cleaned once a year. The main cleaning parts include: cooling water tower, radiator pipes and condenser parts to ensure better cooling effect.
3. When the chiller is not used for a long time, turn off the circuit switches of the water pump, compressor and the main power supply of the cooling water tower in time.
4. Regularly check whether the voltage and current of the chiller are stable, and whether the compressor is running normally. When the chiller is working normally, the voltage is 380V and the current is within the range of 11A-15A.
5. Regularly check whether the chiller refrigerant leaks: refer to the parameters displayed on the high and low pressure meter on the front panel of the host. According to the temperature (winter, summer) temperature changes, the pressure display of the chiller is different. When the chiller is working normally, the high pressure display is usually 11-17kg, and the low pressure display is normal within the range of 3-5kg.
Water-cooled chillers need to be connected with a cooling tower and a circulating water pump to achieve the cooling effect. To ensure the quality of circulating water, you can consider installing a filter at the water source to prevent impurities from entering the pipeline and affecting the operation of the unit.
