How to Install Explosion-Proof Centrifugal Fans
As is well known, explosion-proof centrifugal fans can only be used after they have been installed correctly.
So, do you know how to install an explosion-proof centrifugal fan? In practical applications, these fans not only provide ventilation and dust removal but also offer a certain degree of cooling.
Therefore, after installation and commissioning, they can achieve optimal performance and functionality. Let’s take a look at the installation requirements.
First, prepare the site. Specifically, locate the installation site and ensure the unit is placed on a level surface.
When assembling the explosion-proof centrifugal fan on-site, care must be taken to protect the cut surfaces of the base. After placing the base, use shims to level it.
At the same time, ensure that the bearing plates are tightly secured to the base and maintain proper leveling.
Additionally, before grinding or machining the bearing sleeves, the rotor shaft and housing shaft must be adjusted to meet operational standards.
Next, when assembling the housing, ensure that the specific alignment points are correctly positioned and verify that the pre-set clearances fall within the standard range.
At the same time, confirm that all bolts are securely tightened. The axial clearance of the centrifugal fan unit should typically be approximately 1/100 of the impeller’s outer diameter, and the radial clearances must be evenly distributed.
During adjustment, these clearances should be minimized as much as possible to improve the machine’s efficiency.
When adjusting an explosion-proof centrifugal fan, first determine the reference shaft. Additionally, ensure that the clearances are set appropriately.
Generally, radial runout should be controlled within 0.05 mm, and the angular misalignment should be less than 0.2/100.
When installing the rotor, ensure it rotates freely without obstruction.
The above outlines the installation requirements for explosion-proof centrifugal fans. We hope this introduction helps you better understand the installation process for these units.
Please note that after installation is complete, commissioning is typically required before the unit is put into service.
