| Abstract: | By analyzing reliability of the pump axle filling seal,the paper finds out key factors:axial pressure, friction of the filler,initial gap c 0 and length of the seal ring,which affect sealing degree.On the basis of experimental study the seal ring was conducted design.The filler is made from the selflubricating composite materials of PTFE-Ekonol-Graphite.Checkout indicated properties of the pump obvious raise.Reliability of seal could be guaranteed.1tab.,6figs.,9refs. |
