NBR is an important material used for the stator of progressing cavity pump. The wear mechanisms of different graphite contents of NBR by 45# steel under different loads were investigated. On MPV-600 computer-controlled abrasive wear testing machine, the coefficients of friction were measured continuously. Results showed that wear loss and friction coefficient of NBR decrease with the increasing of...
