What is the primary purpose of using an external source of clean water in a packing gland?

• A. Keep the packing from drying out.
• B. Lubricate the shaft.
• C. Keep gritty material from wearing the shaft sleeve.
• D. Cool the packing gland.

Answer: (B)

The primary purpose of using an external source of clean water in a packing gland is to keep the packing from drying out. When a packing gland is used in a pump or similar equipment, the packing serves to create a seal that prevents leakage of fluids. However, this packing can become dry and brittle over time due to heat and friction. Introducing a clean water source helps maintain moisture in the packing material, ensuring it remains pliable and effective at sealing. This moisture not only extends the life of the packing but also helps maintain efficient operation by preventing leaks. The presence of water can also indirectly contribute to lubrication, but its primary role is to keep the packing material functioning well by preventing it from drying out and deteriorating.
