Abstract:
The paper analyzed the force on the filler sealing in the centrifugal pumps.Through the experiments,the factors affecting the leakage rate were found such as the pressing force,the firction coefficient filler,the oviginal gap,the length of the sealing ring and so on.In the experiments,when the PTFE Ekonol Graphite,self lubricating composite materials were used as the sealing filler of the centrifugal pumps and the dynamic design was made,it showed that the performance of the pumps was obviously better than where the asbestos was.As a result,it may solve the leakage of the pumps and decrease the power loss because of friction.
