Detailed Product Description: | Cooling system clogged capillaries mainly produce ice block, fouling or oil plug. After cooling system blockage, the refrigerant can not cycle, long-term operation of the compressor stop, not inside the refrigeration or cooling slowly, the condenser is not hot, so it is affecting the cooling effect of cold storage. (1) ice block using the oven for heating and drying the parts, the refrigerant in the system compressor, condenser, evaporator, capillary, back to the trachea removed from the refrigerator and put it into an oven heated to dry box the temperature is about 120 ℃, drying time is 4 hours, to be naturally cooled and dried with nitrogen blow-by. (2) fouling with high pressure nitrogen in combination with other methods of dirt will clog capillaries blow, blow through the capillary after, after the refrigeration system for cleaning and drying of the components re-assembly and welding (3) oil filter should be replaced with a new block is, at the same time with high-pressure nitrogen gas is blown condenser refrigeration oil accumulated in part, in the nitrogen gas can be used hair dryer heating condenser. (4) air-cooled unit: Always keep them in good clean air-cooled heat exchanger is strong state, check the condenser fouling problems arise, to promptly remove scale. (5) water-cooled units: Always check the degree of cooling water turbidity, such as cooling water is too dirty to be replaced. Check whether the water supply system to run, run, drip, leak problem. If the pump is working properly, the valve switch is effective, cooling tower. Fans are normal. (6) air-cooled evaporator formula: Defrost should always check the situation, defrosting is timely and effective, it will affect the cooling effect, leading back to the liquid cooling system. (7) frequently observed in the compressor running, check the exhaust temperature, seasonal operation, pay special attention to the system's operational status, the timely adjustment of the supply amount Moms and condensing temperature. (8) listen carefully compressors, cooling towers, pumps, or condenser fan running sound, abnormal timely manner, and check vibration refrigerator compressors, exhaust pipes and ground pins. Finally, teach you a way to maintain the compressor: the initial Moms and internal cleanliness is poor, running 30 days to replace a freeze-drying oil and filter, six months after the operation is changed once again (to the actual situation may be) for higher cleanliness system, running six months later also replace a freeze drying oil and filter, later, as the case may be. |
