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, the valve switch is effective wholesale refrigerator door, 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 electric pan refrigerator door and check the exhaust temperature, seasonal operation, paying particular attention to the operational status of the system, to adjust the system for the fluid volume 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 but also to replace a freeze drying oil and filter, later, as the case may be. Buy cold [preferred] 1. Shandong Huayu civil cold it is more of a cold storage construction, to be built single or multiple layers. The main building is generally reinforced concrete frame structure or masonry structure. Envelope cold civil genus heavy body structure, the thermal inertia of large diurnal fluctuations outside the outdoor air temperature and the envelope surface by diurnal temperature fluctuations caused by solar radiation, greater attenuation in the envelope, the envelope so the inner surface temperature fluctuations on small, easy to storage temperature will stabilize. 2. The combination of this cold cold plate as a single form, the library board for lightweight steel frame structure prefabricated polyurethane insulation panels assembled cold storage doors, the load-bearing member to use more thin-walled steel production. Inside and outside the library board panels are color steel (galvanized steel substrate), the core material for the library board of rigid polyurethane foam or polystyrene foam board pasted. Because in addition to the ground, all the components are in accordance with uniform standards of professional factory pre-sets, assembled at the site, so the construction progress fast, short construction period.
