The heat rejection of the closed cooling tower can be designed and selected according to the hot summer climate. In other solar terms, especially in winter, the heat rejection may be too large. When the closed cooling tower is operating 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. Placed in the tower, according to forced ventilation, spray water and circulating water heat exchange to ensure the actual effect of cooling. Its closed cycle characteristics can ensure that the water consumption is very small, the water quality will not be polluted, and the high-efficiency and high-speed operation of the main equipment is excellently guaranteed, and the service cycle is prolonged. The following cooling tower manufacturer trlon will come and explain in detail. What are the serious consequences of the unclean drainage of the cooling tower?
In the tower body, the water collection trough, spray pipes, and the first number of spray nozzles should be sorted out in time to prevent the accumulation of scale and dirt from clogging the pipes. Look for the components of the packing to find whether there is dirt on it. If there is dirt, it needs to be combed in time to ensure replacement Clean the thermal environment, clean the dirt on the outside of the fan blade, find the angle of the fan blade, the gap between the fan blade and the wind body, and carry out adjustments.
Check whether the floating ball of the copper ball valve in the water collection tank of the closed cooling tower is damaged and whether it is working properly. Check whether there is water leakage in the water collection tank, tower foot, etc., and if there is a leak, make up the glue in time and find the fully enclosed motor. Is the wiring terminal intact? Is there a sensation or abnormal sound when the motor is rotating? Is the motor fixing screw loose? Find out if the rotation of the closed cooling tower reducer is normal. If there is an abnormal sound, replace it with the reducer bearing in time and find the fan blade. Is the even division loose?
For tube-fin heat exchange equipment such as closed cooling towers, in order to better prevent the tube slices from freezing and cracking in the low-temperature climate, the circulating water in the tube slices needs to be drained during shutdown. However, current cross-flow closed cooling towers generally have slow water discharge speed and unclean discharge, which cause the pipe slices to freeze and crack. Others, this is because the drainage is not clean, even if there is no freezing and cracking, if the pipe is partially frozen, water hammer may occur. This caused problems such as the start-up of the whole machine, such as pipe bursts. Therefore, the cross-flow closed cooling tower has frequent freezing and cracking problems in actual use.
