Air Chillers

Industrial chillers are widely used in industrial refrigeration equipment. Their maintenance is very important to ensure their normal operation and extend their service life. The specific maintenance measures and cycles are as follows:   Daily maintenance of the industrial chillers Wipe the outer shell of the chiller regularly to check for signs of damage, deformation or corrosion. Check whether there are blockages at the inlet and outlet of the chiller, such as dust, debris, etc. If there is a blockage, it should be cleaned in time to ensure good ventilation. Check whether the pipe connection of the chiller is firm and whether there is damage, deformation, or leakage on the appearance. Especially for pipe joints, valves and other parts, ensure good sealing. If there is a problem, the pipe should be replaced in time to prevent leakage or affect the cooling effect. Check the operating status of the chiller, such as whether the compressor, water pump and fan have noise and abnormal sounds. Check the outlet water temperature and return water temperature of the chiller to ensure that the temperature is within the set range. Check the pressure of the system, including the refrigerant pressure and water pressure, to ensure smooth water circulation.   Regular maintenance of the industrial chillers For some important parts of the chiller, special attention should be paid during maintenance: 1. Condenser of the chiller The condenser of the water cooled chiller is prone to scaling, and the condenser of the air cooled chiller is prone to dust accumulation. These two factors will not only affect the heat dissipation effect of the chiller, resulting in a decrease in cooling capacity, but will also affect the increase in the power of the chiller and easily damage the compressor of the chiller. Therefore, the condenser must be cleaned regularly, and the specific maintenance time should be determined according to the actual use environment of the customer.   2. Compressor of the chiller After the compressor of the chiller has been running for 1,000 hours, check whether the compressor refrigeration oil is normal; whether the current is normal during operation; and whether there is any abnormal sound during operation.   After the machine has been used for a certain period of time, due to various factors, the pressure switch needs to be tested to see whether it can alarm high and low pressures. For the electric control box, the dust inside should be blown clean regularly, and the screws should be checked for looseness to avoid damage to the machine.   Attached is the regular maintenance schedule for common parts of Hengde chillers Item Maintenance Period Clean the condenser 3 months Check the chilled water pump 3 months Check the wires (corner insulation)  1 month Check the cooling water supply (water-cooled) 1 week Check various safety protection devices 1 month Check the operating current of the compressor and water pump 3 months   Choose Hengde, Choose Perfect Industrial Chillers!
