Multi stage blowers are extremely sensitive to vibration, and abnormal vibration is usually caused by the following reasons: Loose bearing installation: If the standard tightness is not reached when replacing the bearing, it will cause increased vibration during operation

The multi-stage centrifugal fan with welded structure is a high-pressure fan composed of multiple impellers connected in series, and its core components are manufactured using welding technology. Compared with single-stage centrifugal fans, multi-stage design significantly improves the wind pressure output capacity by compressing gas step by step.

​Regular maintenance costs The cost of daily inspections (such as cleaning filters and monitoring vibrations) is relatively low, with a single labor cost of about 200-500 yuan.

Cleaning inspection: Clean the precision machined parts such as rotors and bearings to ensure that there is no rust or rust proof grease residue. The rotating parts should be flexible and free of jamming. Basic acceptance: Check the flatness of the foundation and the position of the anchor bolt holes, with a horizontal deviation of ≤ 0.05/1000. Component verification:
