If your team takes the time to conduct regular and detailed analysis of used or failed packing, you can identify the root cause of premature packing failure and take definitive steps.
If you are trying to increase MTBF (mean-time-between-failures), extend the life of pumps shafts, lower energy use or operational costs, or decrease maintenance efforts, then you will want to read this blog from A.W. Chesterton Company.
This post from their Reliability Matters series instructs you on how to:
- assess the condition of the packing rings (embedded solids, burnt packing, soft or mushy packing rings, brittle or weakened packing, signs of packing extrusion);
- review the condition of the packing fibers (torn or badly worn, uneven, the cutting of the rings)
- identify the most common failure points.
