Pressure Mounted Tungsten Carbide Inserts Deformation of The Sealing Ring

Tungsten carbide due to the high hardness, low thermal conductivity, as well friction materials are widely used in the manufacture of various types under various conditions of the sealing ring, often used as a sealing ring hardware. However, due to the brittle carbide and high prices, in order to save costs and ensure the mechanical strength of the seal ring, often using carbide inserts mounted in place of solid carbide ring. Tungsten carbide ring seat inserts and inserts carbide rings mounted using interference connection. Interference connection to select the amount of interference is directly related to the sealing performance is good or bad, if the amount of interference is too small, it will cause the seal ring and seat relative rotation and detachment, as well as leakage of hydraulic and pneumatic seals medium; If the amount of interference too much will cause plastic deformation or fracture sealing ring.
