  PERSONAL CASE HISTORY – CRACKED FAN/BLOWER IMPELLER In the early years as a Vibration Analyst (2000) I was working at a processing plant in Bathurst NSW. This fluid bed dryer had a fan/ blower around 130Kw, 2 pole motor 2850 RPM. This was located in a fan room with 7 other fans/ blowers. The vibration at the plumber block bearings were starting to rise and at 10mm/sec RMS and there was a concern. So dynamic balancing was scheduled. There was only access to the fan impeller through a small side hatch. The fan could not be fully isolated from other fans so you had moist hot air coming through, which made it hard to see and work. It was impossible to inspect and assess the impeller condition. The inlet ducting could not be removed easily as it was welded which was a poor design. The balancing, instrument was IRD but I also made calculations with polar plots and vectors but the unbalance could not be improved. The vibration amplitude climbed to 15mm/sec RMS over the next week and

  When the curiosity of a Vibration Issue Pays Off Case History by Robert Smith    Primary Regrind Mill Broken Gear   Introduction   I had only been in my Reliability Superintendents role for a few months and I was in the process of setting up a Vibration Analysis Program. This involves looking at all plant locations and the critical of equipment.   As I was inspecting the exterior of this vertical mill gearbox I could hear what I would describe as a clicking sound. The sound did not sound like a high-energy impact but I was curious. I asked a maintenance person working in the area who explained the clicking noise had been there for a while and they did not think it was an issue. The vibration database was not set up at this time for this area of the plant.   To get a reasonable idea of the frequency of the impacts I used a stopwatch. I would count 50 low energy impacts and stop the timing. The timing would vary and remember I was only doing this for basic informati
