Anhui centrifugal fan manufacturer discusses the installation issue of the overall centrifugal fan unit. You should understand that in order to fully utilize the performance and value of centrifugal fan equipment and ensure proper installation. In fact, the entire centrifugal fan unit is usually installed directly on the premise and leveled with double diagonal pads.

When using on-site assembly, corresponding protective measures should be taken. Pay special attention to protecting the cutting surface of the centrifugal fan base to prevent corrosion or operation. When the base is basically placed, a pair of inclined pads should be selected for leveling. In addition, the bearing seat and base should be tightly connected, and the vertical flatness must be maintained at 0.2/1000.

To meet this requirement, the staff should use a level to measure, and the unevenness at the bottom should be kept within 0.3/1000. Then use a spirit level to measure the horizontal division of the bearing seat. Before scraping the bearing shell, the rotor shaft and shell shaft of the centrifugal fan should be calibrated, and the gap between the impeller and the air inlet, as well as the distance between the main shaft and the rear plate hole shaft, should be calibrated. The casing should be adjusted appropriately according to the actual situation to ensure compliance with requirements.

It should be noted that during the installation of the main shaft and bearing shell, strict inspection must be carried out in accordance with relevant regulations, and the interference fit of the bearing cover and bearing shell must be maintained at 0.03-0.04mm. When installing the centrifugal fan casing, the axial and radial clearances between the impeller inlet and the casing inlet should be adjusted to an appropriate range according to the rotor shaft.

This is mainly to further improve the working efficiency of centrifugal fan equipment. In addition, in the intermediate stage, the displacement of the fan shaft and motor shaft should be kept within an appropriate range: the axial positioning motion of the centrifugal fan should be kept within 0.05mm, and the inclination angle should be within 0.2/1000
