Another round of cooling, careful cutting machine frostbite

Keep cold, face cutting machine use in winter cold test, if use undeserved, light affect the equipment operation, and, in turn, affect the production, or damage to the device and the cold water machine, cause unnecessary damage to users, and production.
To avoid the above situation, requires the user to use cutting machine in winter cold water machine, follow the following considerations:
a use, cold water machine (must be at least 0 ° C temperature requirements, is the main reason is because the environment is too low, once the cold water machine stop using, can lead to water the water freezes inside the system, affect the normal use of equipment, serious still can damage the whole cooling system.
2, when the device using the environment temperature in 0 ° C to - 10 ° C, if machine and cold water machine to stop working and not add antifreeze, must be timely to the water in the water system emptying, using compressed air or nitrogen ( Air pressure 5 bra) Will implement the internal emptying, manual will cold water pump and pipeline in the inland waters emptying, cold water machine in working condition is not the cause of equipment ice cause damage. After adding antifreeze, can resist - 20 ° not freezing, but because of antifreeze is corrosive, therefore, to clean the whole water system after winter, after the antifreeze is clean, switch back to normal cooling water.
3, winter cold water machine check points and the solution:
1, the cooling water pump and start the chiller room temperature after the water pump, check the cooling water table and normal temperature water table of the readings. If the pressure or flow alarm, must pay attention to the water system if there is a valve failed to open or have the possibility of ice, to timely treatment, if determined to be frozen, must inform the manufacturer coordination treatment, do not solve itself.
2, after the normal operation of the pump, cooling water temperature is lower than cutting machine allowed to boot the lowest temperature, not normal temperature for a long time. Can set temperature of the cooling water and long warm water is set high 5 ° C, and other problems to see instructions or notify the maintenance personnel, and finally all set temperature of the cooling water and cold water must be adjusted to set temperature ( Set the temperature of the cooling water for 20 - commonly 25 ° C, the normal temperature water set temperature to 25 35°C） 。
