Explanation:
Leakage of seal water around the packing is provided to act as a lubricant between the packing rings and the shaft. The water creates a thin lubricating film that reduces friction, lowers wear, and helps prevent heat buildup at the packing surface, which extends the life of the packing. It also helps flush away entrained solids, but lubrication is the primary purpose. It isn’t an adhesive, a vapor barrier, and while it can contribute to cooling, that is a secondary effect compared to lubrication.
