[Asia Pump Network News] Filled nylon applied to the centrifugal pump seal ring, to extend the service life of its seal ring is important. Centrifugal pump (picture from the network) Analysis: Performance Comparison 1), Tensile strength Mpa: 24.5 filled cast iron for the 156 2), compressive strength Mpa: cast iron 73.5 filled nylon 90 3), shear strength Mpa: Cast Iron 24.3 Filled Nylon 80 Conclusion: Filled Nylon for Centrifugal Pump Seal Rings Advantage 1) Filled nylon seal rings offer long service life. The original machine's cast iron seal ring average life of only 2000h, and the use of nylon packing ring, the service life of more than 8000h. 2) filled nylon seal ring friction characteristics. Has a certain self-lubricating, low friction coefficient, low friction power. 3) nylon packing ring wear resistance. After a year of operation demolition seized, normal wear and tear, wear a very small amount, the size and friction surface basically no significant change. 4) filled nylon sealing ring good cavitation. In the original failure of the cast iron sealing ring can be clearly seen on the metal surface pitting and diameter unequal honeycomb-shaped pits and many axial grooves and other typical cavitation characteristics, and the use of nylon packing ring material effective Avoid cavitation. 5) filled nylon centrifugal pump seal ring, its high mechanical strength, low cost, easy processing.
