What are the common problems of centrifugal fans?

The fan selection and the working principle of the centrifugal fan are already in the front, so I won’t explain these contents below. It is still to spend some time and energy to explain some other aspects, such as the use of centrifugal fans. In the process, what problems do we generally encounter? Once we encounter these problems, how should we deal with and deal with them? These are more important, for centrifugal fans, so below, Ruiapple Electronics will elaborate on Let's take a look at the common sense content it includes, so that everyone can better understand the centrifugal fan.

One of the common problems and aspects: the radial and axial gaps between the inlet bell mouth and the impeller inlet

The radial and axial clearance between the inlet bell mouth and the impeller inlet generally have strict requirements. Because if the gap is too small, the fan will oscillate during operation; but if the gap is too large, then the efficiency of the fan will be affected. Therefore, the gap should be appropriate, neither too small nor too large.

Common problem and aspect two: concrete foundation

The problem with the concrete foundation is mainly looseness or damage. The reason may be that the vibration of the bearing seat is too large, and then the anchor bolts appear loose or cracked, so that the foundation appears loose or damaged.

If you want to deal with this problem, you can increase the touch area between the bearing seat and the lower base, or reduce the force intensity per unit area of ??the base for processing. However, the latter is more commonly used and is also a relatively simple operation. method.

Common problem and aspect three: part of the bearing seat is cracked

This problem is mainly caused by excessive fan oscillation, or severe wear of the fan blades, causing them to fall off. If you want to deal with it, you can only replace the bearing seat so that it can be completed.
