Closed cooling towers usually choose the heat rejection model mainly based on the temperature to make a decision, because in winter, the temperature is relatively cold, and the heat rejection may be too large. In the process of good operation, even if the ambient temperature is high Over 0 degrees, the closed cooling tower will also reduce the water in the pipeline to 0 degrees, and even cause freezing. The closed cooling tower is mainly to put the tube heat exchanger in the tower, and then according to the conversion of forced exhaust, spray water and circulating water to ensure the effect of temperature reduction. Another notable feature of the closed cooling tower is that it can ensure that the water consumption is small, the water quality will not be polluted by other environments, the operation of the main equipment is guaranteed, and the service life of the equipment is extended.
The internal water collection tank and sprinkler water supply pipeline of the closed cooling tower are composed of many kinds of combinations. Therefore, everyone must clean it in time to prevent the pipeline from being blocked by scale and dirt, and timely check whether there is dirt on the filling part. If dust is found, timely sorting must be achieved to ensure the cleanliness of the heat transfer environment, timely cleaning of the dirt on the surface of the fan blades, and timely adjustments.
In addition, you also need to check whether the floating ball on the copper ball valve in the sump of the closed cooling tower can operate normally, check whether there is water leakage in the sump, tower foot, etc., if there is a problem of water leakage, you need to make it immediately glue.
Check whether the sound of the motor is abnormal when it is running, whether the screws that secure the motor are loose, and timely check whether the operation of the cooling tower reducer is generally abnormal. If abnormal noise occurs, the reducer must be replaced immediately For rolling bearings, check whether the fan blades are evenly dispersed in time.
In fact, for tube-rotating fin heat exchange equipment such as closed cooling towers, in order to better not allow the tube slices to be frozen at low temperature in winter, the circulating water in the tube slices is usually removed completely in time when it is stopped. However, current cross-flow closed cooling towers also generally have the problem of slow drainage speed or dirty drainage, which caused the tube slices to freeze and break.
If the water drain in the closed cooling tower is not clean, even if it is not frozen, there will be some freezing conditions in the pipeline, which may cause the occurrence of tube bursts in the future, so this type of problem must be done as much as possible. Pay attention.
As a type of evaporative cooling tower, a combination of closed cooling towers, the effect of evenly distributed spray water shown in the future may be very good. At this stage, many manufacturers have also used closed cooling towers in order to make the effect of waste heat treatment more significant.
