Help needed: vibration problem with Shaanxi blowers
Thread Content
The horizontal vibration at the impeller end of the fan is high; the foundation bolts have been checked and are fine. What could be causing this?
The problem is the dynamic balance of the shaft, or the bearing clearance!

Have any teachers encountered this situation?
The fan is used to convey exhaust gas; the temperature of the medium is around 200 degrees, and there was a fire inside the fan as well.
First, do a dynamic balance test; check the bearings when reinstalling
Yes, just perform low-speed dynamic balancing
1. Conduct online monitoring to check the spectrum. 2. Check for changes in oil pressure, operating conditions, and any looseness. 3. Disassemble to inspect the bearing shells and balance discs; perform dynamic balancing on the rotor, and conduct flaw detection on the blades
