Testing Study on Wear Mechanism of Fluororubber by 45# Steel under Different Speed in Oil Medium

摘要

Fluororubber is an important material used for the stator of progressing cavity pump,which works under high temperature and high pressure conditions transferring oil of high viscosity.With sand-content oil as medium,the wear mechanisms of fluororubber by 45# steel under different speed and different initial temperature were investigated.On MPV-600 computer-controlled abrasive wear testing machine,the coefficients of friction (COF) were measured continuously for 10800s.The varying law of COF was summed up and the wear mechanism reflected was concluded.
