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:? Please scold degree should always observe the compressor oil and oil return and oil discovery 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 to be replaced. Check whether the water supply system to run, run, drip, leak problem. If the pump is working properly refrigerator door manufacturers, valve switch is effective, cooling towers, air is normal. For cold unit: always check the condenser fouling problems arise refrigerator door fittings, 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). For higher cleanliness system, six months after the operation and should be replaced every freeze drying oil filter brand refrigerator door, later, as the case may be. Refrigerator door [preferred] Shandong Huayu maintenance folding one, or long-term cold storage installed after you stop using the refrigerator door again, the cooling rate must be reasonable: 8-10 ℃ control day is appropriate, should be kept at 0 ℃ for some time. Second, the cold storage library board maintenance, attention should be noted that the use of a hard object library body collision and scratching. Because the library board can cause depression and rust, a serious cause reduced insulation performance of the Local Library. Third, the cold sealing parts and maintenance, because the assembly is to fight cold storage insulation board made by a number of blocks, so there is a certain gap between the plates, the construction of these gaps will be sealed with a sealant to prevent air and moisture from entering. Therefore, the use of some parts of seal failure timely repair. Fourth, the cold ground maintenance, general assembly of small cold storage on the ground using the insulation board, should be used to prevent cold ground there are a lot of ice and water, if there is ice, cleanup must not use a hard object beat, damage to the ground.
