Why Trending Data is Important

Case Study: Predictive Activities – Trending

{{cta(‘236ffbef-9183-4718-9aa0-b9b2e33e85c9’)}}

This case history takes place in a packaging facility in Virginia. The packer on module E5 was checked for vibration integrity during a pre- machine care evaluation. A problem was detected in the folding arm gearbox. The frequency characteristics indicated a bearing was deteriorating.

This seems very straight forward but let’s put the reality of the situation into the problem detected. The gearbox is located in a section of the packer that is not easily accessible. To do the necessary repairs it will require separating the two sections of the machine. When the packer is split it will take an additional two days of work before the unit can be restored to service.

The maintenance leader is not a believer in the ability of the technician to make a vibration call correctly. He has vowed to bring the technician and the technician’s boss under the scrutiny of the organizations leadership for poor performance if the call is
wrong. The product this packer is packing is in a sold out position. See how trending data on this product needed upgrading.
