This is the fifth video case study from the ‘Book of Gold, Practical Condition Monitoring Case Studies’ (#BookofGold) by JPS Reliability. As part of a routine data collection program, a slight change was noted in the fan motor vibration levels. Vibration monitoring frequencies were increased to daily as the defect detoriated. This process enabled planning and a controlled change out of the motor.
This is the fourth video case study from the ‘Book of Gold, Practical Condition Monitoring Case Studies’ by JPS Reliability. In this video James is not in his shed (it’s too cold), instead he’s in front of the Christmas tree! James hopes to provoke discussion around the questions: how early do you want to detect the defect, what caused the failure, and how can the defect be eliminated. This case features a set of pumps on separate metal base frames secured to the same concrete bed. The motor bearing has a suspected sub-surface fatigue defect.
