The most important point is to keep the surface of the chiller filter clean, air around the filter, clean the filter regularly, and usually blow the filter once with compressed air for three weeks. Reduce the occurrence of mold "pour sweat" phenomenon. Before stopping the plastic machine, first turn off the cooling sluice gate of the auxiliary mold, or turn off the cold water mechanism, so that the water temperature in the cavity rises, the mold will not produce rust. If the chiller has been used for more than half a year, or low pressure The engine often fails, or the cooling capacity is reduced. Please arrange the technician to clean the radiator. (If the chiller has a pressure gauge installed, the pressure of the high pressure gauge is higher than 300 PSI. If it exceeds, the surface of the radiator should be cleaned to keep it clean and improve the radiator effect. ). If the industrial chiller is still faulty after multiple cleanings as described above, please arrange for the repairs. If the industrial chiller is out of service for a period of time, the pump pump may solidify due to the solidification of the water condensate. When the machine is turned on, the pump rotor must be loosened to avoid the pump leaves not turning, resulting in burnt fuses. (Applicable to chillers below 5) chiller maintenance The cleaning of the radiator first stops the machine, removes the filter of the machine plate, and blows off the dust on the surface of the filter with compressed air. If the radiator is dirty, it should also be cleaned together. If there are conditions, spray the air-conditioning cleaning agent on the surface of the heat-dissipating net. After a few minutes, rinse with water and repeat until the surface of the filter is clean.
