The cooling tower can be designed according to the summer's climate. When the closed cooling tower operates at high speed, even if the ambient temperature exceeds zero, the closed cooling tower may reduce the water in the tube to zero, or even freeze. The closed cooling tower places the tubular heat exchanger (heat exchange coil) in the tower, and ensures the actual cooling effect according to the heat exchange between forced ventilation, spray water and circulating water. Its closed circulation features can ensure that the water consumption is very small, and the water quality will not be polluted, which guarantees the high-speed operation of the main equipment and prolongs the service life=“ http://www.isunfly.net/ " target="_ Blank "> < strong > closed cooling tower?
In order to ensure the cleanness of the heat exchange environment, clean the dirt on the surface of the fan blade, find out the angle of the fan blade and the gap between the fan blade and the air carcass, and carry out the adjustment.
Find out whether the floating ball of the copper ball valve in the water collecting tank of the closed cooling tower is damaged, whether the work is normal, and whether the water leakage is found in the water collecting tank and tower foot. If there is a leakage point, timely replenish the glue, find out whether the wiring terminal of the fully enclosed motor is in good condition, whether the motor rotation is sensational or abnormal, whether the motor fixing screw is loose, and find out the reducer of the closed cooling tower Whether the rotation is normal. If there is abnormal sound, replace it with the reducer bearing in time to find out whether the fan blade is evenly divided and whether it is loose.
For the segment type heat exchange equipment such as closed cooling tower, in order to prevent the segment from frost cracking in low temperature climate, the circulating water in the segment should be removed during shutdown. However, at present, the phenomenon of slow water discharge and unclean drainage in the cross flow closed cooling tower generally leads to the frost cracking of the segments. Other reasons are that the drainage is not clean, even if there is no frost crack, if the pipe is partially frozen, the water hammer phenomenon may cause the whole machine problems such as starting the machine and bursting the pipe. Therefore, the cross flow closed cooling tower has frequent frost cracking problems in practical use.
