SL3ZB— 3 7HJ型三缸单作用恒排量往复泵是针对油田注聚合物的需要而开发的。这种新型泵采用凸轮传动机构 ,通过对凸轮廓线的设计 ,实现了恒排量输出特性 ,从根本上解决了曲柄连杆机构往复泵的排量、压力脉动问题 ,无须配备排出预压空气包、吸入缓冲器和灌注泵 ,自吸性能良好。着重叙述了这种泵的主要技术参数、工作原理及结构特点。 1 1台泵历经一年多的使用情况证明 ,泵排量恒定 ,压力无波动 ,运转平稳 ,能充分满足注聚合物工艺要求。
SL3ZB- 3 7HJ type three-cylinder single-acting constant displacement reciprocating pump is developed for the needs of oilfield polymer injection. This new type of pump uses a cam drive mechanism. Through the design of the cam profile, the constant displacement output characteristic is realized. The problem of displacement and pressure pulsation of the reciprocating pump of the crank and rod mechanism is fundamentally solved. It is unnecessary to provide the discharge pre-compressed air Packs, inhalation bumpers and infusion pumps, self-priming performance is good. Emphatically described the main technical parameters of the pump, working principle and structural characteristics. 1 1 pump after more than a year of use proved that constant displacement pump, pressure fluctuations, smooth operation, can fully meet the polymer injection process requirements.
