Safe operation management of axial flow fans
Thread Content
Axial flow fans are key equipment in metallurgy and petroleum refining catalytic cracking processes. They are widely used due to their ease of load adjustment and energy efficiency. However, due to the special structure of these fans, the blades represent their weak point; even minor carelessness can lead to significant losses. The image below shows an example of damage. Therefore, strengthening equipment management cannot be taken lightly at all.
Such a large axial flow fan?
Didn’t it cause an accident to be in such damaged condition?
What’s become of the damaged/stator blades?
What causes it? Surge?
I asked how it was damaged. For example, was the graphite bearing of the stator blade broken? Slider movement? Wait, how was it hung up? Is it caused by excessive vibration or something else? From the perspective of the equipment, not from a process perspective.
It was taken at the manufacturing plant; the specific reason wasn’t asked.
