Maintenance of closed cooling tower

Maintenance of closed cooling tower

Regarding the maintenance of the closed cooling tower, it can be divided into daily cleaning work and daily maintenance. Then, in these two aspects, let's talk about the maintenance of the closed cooling tower.

　　 Closed cooling tower is a tube heat exchanger (heat exchange coil) placed in the tower, through forced ventilation, spray water and circulating water heat exchange to ensure the cooling effect. Its closed cycle characteristics can ensure that the water consumption is very small, the water quality is not polluted, and the efficient operation of the main equipment is excellently guaranteed, and the service life is extended. When winter comes or the outside temperature is low, the spray water system can be stopped to save water and energy. With the increasing scarcity of water resources and the implementation of national energy saving and emission reduction policies, closed cooling towers will surely play an important role in the energy industry, power electronics, food processing, air conditioning and refrigeration industries in the next few years.

　　 Regarding the maintenance of the closed cooling tower, it can be divided into daily cleaning work and daily maintenance. Then, in these two aspects, let's talk about the maintenance of the closed cooling tower.

　　 1. Daily cleaning part

　　 1. The water collection tank, spray pipe, sprinkler head and other parts inside the tower body should clean up dirt in time to avoid the accumulation of scale and dirt and block the pipeline.

　　2. Check the packing part to see if there is dirt on it. If there is dirt, it needs to be cleaned up in time to ensure a clean heat exchange environment.

　　3. Clean the dirt on the surface of the fan blade, check the angle of the fan blade, the gap between the fan blade and the wind, and adjust it.

　　 2. Daily maintenance part

　　 1. 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.

　　2. Check whether there is water leakage in the water collection tank, tower foot, etc., if there is any leakage, make up the glue in time.

　　 3. Check whether the wiring terminals of the fully enclosed motor are intact, whether there is vibration or abnormal sound when the motor is rotating, and whether the motor fixing screws are loose.

　　4. Check whether the reducer of the closed cooling tower rotates normally. If there is abnormal noise, replace the bearing of the reducer immediately to check whether the fan blades are evenly distributed for looseness.

　　 5. Check whether the belt is damaged or cracked, and replace it with a new belt if necessary. It is recommended to change the belt within 2 months.
