A chiller is an energy-efficient machine that achieves cooling by vapor compression or absorption cycles. Chiller full name for the cooling water recycling machine, also known as the refrigerator, cooler, freezer, chiller, ice machine, small chiller, industrial chiller, chiller, chiller, laser chiller, because of the wide range of industries Use, so according to different industries, their aliases countless. First, the pump failure reasons: 1, pump AC contactor overload protection action; 2, the pump capacitors burn out; 3, the pump itself, such as the coil burned, bearing necrosis. Method of exclusion: 1, Tap over-current protection RESET reset health can be. 2, replace the capacitor. 3, replace the pump, pump replacement should pay attention to the steering. Third, high and low voltage switch failure reasons: 1, the filter is blocked 2, the lack of system refrigerant caused by low pressure alarm; 3, through the cooling water to stop working caused by high pressure alarm; 3, heat exchanger cooling fan to stop working caused by high pressure alarm. Method of exclusion: 1, to clean the filter or replace the same type of filter. 2, to the system to add refrigerant. 3, check the cooling water circulating pump work is normal, and repair or replacement 4, check the heat exchanger cooling fan is working properly, and repair or replacement. note: 1, remove the above failure should pay attention to check the power connection lines are disconnected. 2, when the machine failure should be repaired by professionals, it is strictly prohibited in the machine failure will run the machine. Second, power failure reasons: 1, mains disconnect, lack of phase, unstable, 2, check phase sequence protection is burned out; 3, fuse burn out; Method of exclusion: 1, check the mains is normal, to be normal again after the work of electricity. 2, replace phase sequence protector. 3, replace the fuse. Water chiller application industry: Chiller is mainly used in plastic industry: plastic molding, injection molding, extrusion, blowing, thermoforming, machinery industry: laser technology, welding, mechanical cutting, non-cutting processing, casting, electroplating, electronics industry: surface treatment, electroplating , Electrophoresis, medical equipment, electronics industry, circuit board manufacturing, electronic chip manufacturing, chemical industry and other industries: chemical, paper, pharmaceutical, food processing, aluminum, aluminum, tempered glass, coated glass production, Sin, jewelry processing, leather, fur processing, ink production, aquaculture.
