Abstract：The field service problems of butylene feeding pump used in a large scale high pressure reciprocating reactor are studied.The influence factors of valve lift-range,valve clearance flow rate,impulse and spring force etc are discussed.It is concluded that changing the structure of valve is the fundamental means to avoid original valve breaking down frequently and to extend it’s operating life.Bicyclo-valve which yields comparatively good effect in the production should be used in the high pressure reciprocating pump.inspiration valve;exhaust valve;valve plate;high pressure reciprocating pump;lift range
