What Issues Might Arise During the Operation of High-Temperature Cabinet-Type Centrifugal Fans?

In addition, there have been numerous reports on the selection of high-temperature cabinet-type centrifugal fans and the operating principles of non-high-temperature cabinet-type centrifugal fans. If you are unsure about these topics, you can search for relevant information on this website. How should these issues be addressed and resolved? These points are particularly important for high-temperature cabinet-type centrifugal fans. To help you gain a deeper understanding of stainless steel centrifugal fans, let’s discuss the knowledge regarding high-temperature cabinet-type centrifugal fans included in this article. 1. Radial and Axial Clearances Between the Air Inlet and the Impeller Inlet There are strict requirements for the radial and axial clearances between the air inlet and the impeller inlet. If the clearance is too small, the fan will vibrate during operation. However, if the clearance is too large, it will affect the fan’s efficiency. Therefore, the clearance must be appropriate—neither too small nor too large. The clearance calculations for high-temperature cabinet-type centrifugal fans must be accurate. Depending on various operating conditions and requirements, the clearance distance needs to be adjusted. Clearance between the air inlets of high-temperature cabinet-type centrifugal fans 2. Concrete Foundation for High-Temperature Cabinet-Type Centrifugal Fans The primary issues with the concrete foundation of high-temperature cabinet-type centrifugal fans are loosening and damage. This is because excessive vibration of the bearing housing may cause anchor bolts to loosen or break, leading to loosening or damage of the foundation. To address this issue, the contact area between the bearing housing and the lower foundation can be increased, or the stress amplification factor per unit area of the foundation can be reduced; the latter is a more common and simpler method. 3. Partial Damage to the Bearing Housing The primary causes are excessive vibration in the high-temperature cabinet-type centrifugal fan and excessive blade wear. To resolve this issue, the bearing housing must be replaced. There are many reasons for vibration in high-temperature cabinet-type centrifugal fans, so they will not be detailed here.
