| Abstract: | The failure of a gear pump mechanical seal for high-viscosity dope of acetate fiber was analyzed,including seal face wear and deformation,elasticity loss and breakage of corrugated pipe,0 ring failure.The structure,material and installation technique of the mechanical seal were reformed.The results showed that the leakage of high-viscosity dope resulting from the high pressure and vibration of gear pump can be solved by using stationary and rotating rings of impregnated polytetrafluoroethylene resin, corrug... |
