Repair and maintenance of centrifugal fan


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

Maintenance of the casing and air inlet chamber

Except for regular inspections of the casing and inlet chamber for serious wear and tear, and removal of serious dust accumulation, these parts do not require other special maintenance.

Regularly check whether all fastening bolts are tight.

1. Maintenance of bearing

Frequently check the oil supply of the bearing lubricating oil. 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.

2. Maintenance of other supporting equipment

For the maintenance of various supporting equipment including motors, electric actuators, instruments and meters, please refer to their respective operating instructions. These operating instructions are provided by various supporting manufacturers, and SIMO Blower will provide these instructions to users.

3. Maintenance when centrifugal fan is out of use

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