【 Weak current College 】 cold storage: library of maintenance 】

A cold new installed or after long-term disabled, reuse, cooling rate must be reasonable: in 8-day control is appropriate, in 100C 00C keep for a period of time. B Library Board protection: note the use of hard objects to a library of collision and scratching. Because you can create a Library Board of SAG and rust, a serious cause of partial insulation performance library. C seal protection, because some fabricated from cold storage is block insulation board pieces, so the plate there is a certain gap between the construction of these gaps will use sealant to seal, to prevent air and water. So in use on some seal failure of parts of timely patching. D surface protection, General small use of prefabricated cold insulation Board, use the freezer should prevent ground there are plenty of ice and water, ice, cleanup is never use hard-knock, damage to the ground. Daily for maintenance and repair of refrigeration system is running in the how to maintain the initial operation of units 1.: frequently observe compressor oil and the oil and oil, the arguments of found oil dirty or oil level lowering to solve, so as to avoid poor lubrication. 2. in the case of air cooling units: should always clean air cooler to keep good heat strong State. For cold water unit: to always check the degree of opacity of cooling water, such as the cooling water is too dirty, to be replaced. Check the water supply system is not running, the risk, drip, leak problems. The pump is working, the valve switch is valid, the cooling tower. fan is normal. For wind turbine: always check a scaling problem, the condenser to the timely removal of scale. 3-for-air cooling machines: the evaporator defrosting to regular checks, whether timely and effective defrosting, affect the refrigeration effect, leading to liquid cooling system. 4 regular observation of the compressor running, check the exhaust temperature, when run in the off-season, paying special attention to the system's operating state, the timely adjustment of system for liquid and condensing temperature. 5 listen compressors, cooling towers, pumps or condenser fan operation sound, abnormal findings in a timely manner, while at the same time check the compressor, the exhaust pipe and the foundation of vibration. 6 on compressor maintenance: initial system internal cleanliness, running in 30 days you are replacing a frozen oil and dry filter, running half a year later and then replace the time (according to the actual situation). For cleanliness for higher system, after running for half a year to replace a frozen oil and dry filter, as the case may be.
