Electric double sliding door open [preferred] Shandong Huayu routine maintenance and repair of refrigeration systems and how to maintain an operation, the initial operation of the unit:? Should always observe the compressor oil and oil return and oil please scold degree cold storage doors translation and found dirty oil or oil fell to promptly resolve to avoid poor lubrication. 2, for the air-cooled unit: Always clean air-cooled heat exchanger is to keep a good state. For water-cooled units: Always check the cooling water turbidity, such as cooling water is too dirty refrigerator door, 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 towers, air is normal. For cold unit: always check the condenser fouling problems arise, to promptly remove scale. 3, for the air-cooled engine type evaporator: should always check the defrost case, defrosting is timely and effective, it will affect the cooling effect, leading back to the liquid cooling system. 4, frequently observed compressor running, check the exhaust temperature, seasonal operation, paying particular attention to the operational status of the system, to adjust for the amount of fluid systems and condensing temperature. 5, listen carefully compressors, cooling towers, pumps, or condenser fan running sound, abnormal timely treatment, while checking vibration compressors, exhaust pipe and to the foot. 6, compressor maintenance: initial internal system cleanliness poor run 30 days to replace a freeze-drying oil and filter after running again replaced every six months (according to the actual situation).
