Case 1 :Blower Excessive Vibration During Operational Had Caused Cracking on Several Frame Structure

Location : Malaysia


Task performed by AFCM in response to a request by client for ODS study on chlorination blower. The study was to evaluate and examine the rigidity and integrity of machine and structure motion during operational using ODS method. Besides that, bump-test was also performed to find an evidence of structure resonance. The task was done on each structural membrane which supporting the blower and natural frequency (Nf) was identified. Over 180 point’s data were collected around the unit covering machine components (motor & blower), skid, floor, beam and piping. Post processing of data has decided to simulate at the 1X force response.

Equipment : Blower
