Fan maintenance of closed cooling tower? Fan is the main component of closed cooling tower. The quality of fan and the air volume of fan affect the working efficiency of cooling tower. The fans used in the closed cooling tower are made of FRP, aluminum alloy and other materials. Different materials also have great differences in quality and service year. Therefore, proper maintenance is more important. Pay attention to a few points in the maintenance of fans of closed cooling tower.
Fan maintenance of closed cooling tower?
1.Add lubricating oil regularly. The blade rotation of the fan is driven by the high-speed fan. The shaft of the motor is prone to lack of oil, resulting in poor rotation and increased friction. Reduce the service life of the fan, improve the damage rate, add lubricating oil regularly and keep the speed smooth.
2. Calibrate the air duct regularly. When some wind turbines, especially those made of glass, are rotating at high speed, there will be the problem of improper inclination of the wind turbines, and the friction of the wind blades will be damaged. It is necessary to regularly send professional maintenance personnel to correct the position of the wind turbines, or to reinstall the position. Ensure the average and reasonable clearance between the air duct and the air blade.
3. Replace the damaged blades in time. Generally, there are three blades. If one of the blades is damaged, the wind force will be different early, and the wind force will be unbalanced for a long time. When the blades rotate at high speed, the motor force will be different. When the motor shaft is bent and displaced, the force and friction at a certain point will be increased.
4. Strengthen the monitoring of fan vibration. The vibration of high intensity will make the connecting bolts of the unit loose or even fail. Therefore, the vibration of the fan must be monitored regularly. When the vibration value exceeds the standard, the cause shall be repaired. In addition, all bolts and nuts shall be inspected regularly to avoid accidents caused by bolt looseness caused by vibration.
The fan disassembly, inspection and maintenance of closed cooling tower shall be carried out by professional technicians, the assembly must be complete, and the installation position of components must be correct. The maintenance should be proper.
