What issues might arise during the operation of centrifugal explosion-proof fans?

Furthermore, numerous articles have been published regarding the selection and operating principles of centrifugal explosion-proof fans. If you are unsure about these matters, you can search for relevant information on this website. Today, I came across some information online regarding centrifugal explosion-proof fans. For instance, what issues typically arise when using centrifugal explosion-proof fans? If these issues occur with centrifugal explosion-proof fans, how should they be addressed and resolved? These points are of great importance for centrifugal explosion-proof fans. To help everyone gain a deeper understanding of stainless steel centrifugal fans, let us discuss the knowledge covered in this article. 1. Radial and axial clearances between the air inlet and the impeller inlet There are strict requirements regarding the radial and axial clearances between the air inlet and the impeller inlet. If the clearance is too small, the centrifugal explosion-proof 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 calculation for centrifugal explosion-proof fans must be correct. Depending on various operating conditions and requirements, the clearance distance needs to be adjusted. The clearance between the impeller and the inlet of the centrifugal explosion-proof fan 2. Concrete Foundation The main issues with concrete foundations are loosening and damage. This is because excessive vibration of the bearing housing may cause the anchor bolts to loosen or break, leading to loosening or damage to the foundation. To resolve 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 straightforward method. 3. Partial damage to the bearing housing The main causes are excessive vibration of the centrifugal explosion-proof fan and excessive wear of the blades. To resolve this issue, the bearing plate must be replaced. There are many reasons for vibration in centrifugal explosion-proof fans, so these will not be detailed here.
