Cooling tower fans are the core equipment of circulating water system. In terms of circulating water equipment management, cooling tower fans account for a large proportion in terms of equipment quantity, maintenance workload, power consumption, etc. The number of fans accounts for 57% of the total equipment in the workshop, maintenance time accounts for 60% of the total, and power consumption accounts for 22% of the total. How to improve the energy saving and consumption reduction efficiency of cooling tower fans and ensure the long-term operation of equipment, the following is a brief description of the main methods and measures:
1. The cross-flow cooling tower should control the height from the top of the packing to the lower edge of the suction section of the fan to be equal to or greater than 0.2 times the diameter of the fan.
2. The height of the airflow contraction section between the top surface of the packing of the counterflow cooling tower and the inlet of the air duct shall meet the following requirements:
a When the tower top cover plate is flat, the top angle of the airflow contraction section calculated from the top surface of the filler should be less than 90 °. When the cooling tower is provided with a guide ring (umbrella) under the flat top cover plate, the top angle of the airflow contraction section calculated from the top surface of the water collector can be 90 ° ~ 110 °.
B When the top cover plate of the cooling tower is of the contraction type above the self-collector, the top angle of the cover plate of the contraction section should be 90 ° ~ 110 °.
3, cross-flow cooling tower water spray packing from the top to the bottom should be to the vertical axis of the tower contraction inclination, drop type water spray packing shrinkage inclination should be 9 ° ~ 11 °, film type water spray packing shrinkage inclination should be 5 ° ~ 6 °.
4. The counterflow cooling tower with air inlet on both sides should be equipped with a middle windshield partition. The upper edge of the partition is 200~300mm from the bottom of the packing support beam, and the lower edge extends below the water surface of the collecting pool of the tower.
5, cross-flow cooling tower should be set to prevent the air from the bottom of the filling to the water surface between the short circuit flow measures.

How to learn to maintain the glass fiber reinforced plastic cooling tower can extend the service life, the following small series for the big cooling tower home to explain the following points in detail:
After entering the winter, the cooling tower is basically in a shutdown state. When the cooling tower is out of service for a long time, the parts of the cooling tower should be overhauled and maintained immediately. The cooling tower friendship reminds us that the following matters should be paid attention to when the cooling tower is out of service for a long time:
1. First, after the cooling tower is shut down, discharge the excess water inside the cooling tower water receiving tray and pipeline, and clean up the silt and impurities inside the cooling tower water receiving tray.
2. Overhaul the damage of the packing and water distribution nozzle inside the cooling tower, replace the damaged immediately, and clean up the impurities inside the packing.
3. Check the motor circuit for damage or aging.
4. Overhaul the cooling tower fan, and apply antirust paint or lubricating oil for anti-corrosion maintenance. After treatment, use plastic film to seal and save, and check the gear oil in the reducer.
5. Overhaul the fasteners of the cooling tower and apply lubricating oil or antirust paint for maintenance.
6. Overhaul the overall steel structure frame of the cooling tower. If there is rust, please do anti-corrosion maintenance after rust removal.
Under normal circumstances, the cooling tower should be shut down for more than 4 months, and the overall inspection should be carried out. Local maintenance can be carried out for more than one month, such as fan anti-corrosion, nozzle maintenance, water receiving plate desilting. After a long shutdown, the gear oil should be completely replaced in the cooling tower reducer when the cooling tower is used in the coming year. If the cooling tower is used in winter, the motor can be turned off, and the ideal cooling effect can be basically be achieved by the cooling tower itself, due to the relatively low temperature in winter, icing will inevitably occur when the air inlet of the cooling tower is used for a long time. The reverse rotation of the motor can be used for deicing treatment. However, the reverse rotation of the motor should be watched by special personnel, and the reverse rotation time should not be too long.
