Precautions for centrifugal fan maintenance

Correct maintenance is an important guarantee for the safe and reliable operation of the centrifugal fan and the improvement of the service life of the centrifugal fan. Therefore, we must pay full attention to the use of centrifugal fan.

1. Repair and maintenance of impeller

In the early stage of impeller operation and all regular inspections, whenever there is a chance, the impeller must be inspected for defects such as cracks, wear, and dust. Whenever possible, the impeller must be kept clean, and the dust and rust on it must be regularly brushed with a wire brush, because as the operation time increases, these dusts cannot be uniformly attached to the impeller, resulting in The balance of the impeller is broken, which causes the rotor to vibrate.

2. Maintenance of fan and air inlet chamber

Except for regular inspection of the casing and air intake chamber for serious wear and tear, and removal of serious dust accumulation, other special maintenance is not required for these parts. Regularly check whether all fastening bolts are tight. For fans with compression bolts, press the butterfly springs on the feet to the installation height specified in the drawings.

3. Maintenance of bearing department

Frequently check the supply of lubricating oil in the bearing. If there is oil leakage in the box, you can tighten the bolts of the end cover a little bit. If this is not enough, you may have to replace it with a new seal packing.

4. Maintenance of other supporting equipment

For the maintenance of various supporting equipment including motors, electric actuators, instruments, meters, etc., please refer to their respective instruction manuals. These operating instructions are provided by the supporting manufacturers, and our manufacturer will provide these instructions to the user in a random box.

5. Maintenance when the fan is out of use

When the fan is out of use, when the ambient temperature is lower than 5°C, the remaining water in the equipment and pipelines should be drained to avoid damage to the equipment and pipelines by freezing.
