What is the reason for the short service life of the flexible graphite braided packing (packing material) in centrifugal pumps or reciprocating pumps that use packing seals?
The short service life of flexible graphite braided packing (gasket) may be caused by the following reasons: 1. The packing being either over-compressed or too loose, which affects the sealing performance and accelerates wear. 2. The high speed of the pump increases the friction and temperature of the packing, leading to rapid aging. 3. Wear of the pump’s bearings or inaccurate alignment can cause shaft vibration or deflection, increasing the wear of the packing. 4. The medium used is corrosive or contains solid particles, accelerating the damage to the filler. 5. Inadequate cooling or lubrication systems, resulting in overheating or dry grinding of the packing. 6. Irregular packing replacement cycles or improper technical operations. .
Polytetrafluoroethylene is added to create a composite woven filler (containing flexible graphite).
