In the normal operation of the water chiller, it is unavoidable to have the effect of cooling because of dirt or other impurities. Therefore, in order to prolong the service life of the main unit and make the cooling effect reach a better state, the maintenance and maintenance work should be carried out regularly to ensure the running quality of the chiller and to improve the production efficiency.
For the convenience of the new and old customers to understand the maintenance project of water-cooled chiller, the refrigeration engineer specially arranged it as an operating manual for sharing. The details are as follows:
First, regular inspection of water chiller voltage, electricity flow is stable, the compressor running sound is normal, cold water machine normal work, the voltage is 380V, the current in the range of 11A-15A is normal.
Two, regularly check the cooling water chiller whether there is leakage phenomenon: refer to the main panel, high and low voltage table display parameters to determine. According to the temperature (winter, summer) temperature changes, cold water pressure display is also different, when the chiller works normally, the general high voltage display 11-17kg, low voltage display 3-5kg range is normal.
Three. Check whether the water heater, the water heating system is normal, whether the cooling tower, the fan and the sprinkler shaft work well, and whether the water supply in the water cooler is normal.
Four. The chiller should be cleaned in six months, and cleaned every year. The main cleaning parts include cooling tower, radiator pipe and condenser part, so as to ensure better cooling effect.
Five, cold water captain time is not used, should promptly shut down the water pump, compressor and heat sink water, total power supply circuit switch.
Water cooled chiller and cooling tower supporting circulating water pump is connected to achieve the cooling effect, in order to ensure the quality of the circulating water, can consider to install the filter in the water, to avoid impurities into the pipeline operation of unit. In addition, the maintenance of water chiller is relatively complicated. If there are no professionals in the company, it is recommended to ask the chiller supplier to arrange for professional technicians to deal with it.
