Axial fan inspection and maintenance
The operation inspection and maintenance of the axial flow fan are very important. Only when the axial flow fan is regularly maintained and maintained, can it work better for us. When the axial fan is in normal operation, it is critical to monitor the current of the motor. The current is not only an indicator of the load of the centrifugal fan, but also a weather forecast for abnormal safety accidents. Secondly, always check whether the vibration of the motor and the centrifugal fan is normal and whether there is friction or abnormal noise. For centrifugal fans operating in series, attention should be paid to monitoring whether the centrifugal fans are operating under low-frequency oscillation conditions.
During normal operation, if the following conditions are encountered, shut down and check first:
1. The centrifugal fan produces obvious vibration or rubbing sound.
2. The current of the motor suddenly rises and exceeds the rated voltage of the motor.
3. The temperature of the motor's rolling bearing has increased significantly.
Maintenance of axial fan:
1. There is no common fault operation, and it can only operate when the centrifugal fan equipment is completely normal.
2. Check on time whether the centrifugal fan blades are loose and whether the gap between the blades and the blower is normal.
3. Check the tightening condition of the anchor bolts of the motor and the shell connection on time, and check whether the shock-absorbing seat and the basic connection are intact.
4. Eliminate ash and stains on the leaf area on time.
5. Remove and replace the lubricating grease for the rolling bearings of the motor on time. Generally, add oil once every three months. The lubricating grease can also be replaced according to specific conditions.
In order to make the axial flow fan work better, we should carry out regular inspection and maintenance on the axial flow fan, so as not to cause problems during operation and cause irreparable losses.
