| 摘 要： | 针对某进口大型高压往复式反应器丁烯进料泵在现场使用中出现的一系列问题,对该泵阀升程、阀隙流速、冲击力、弹簧力等影响因素进行了分析研究和计算,指出阀的结构型式的改变是解决原泵阀频繁出现故障问题、延长其使用寿命的根本途径。对高压往复泵进、出液阀采用双环阀的改良设计方法,圆满解决了所出现的故障问题,并在产品上得以应用。

| 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 |
