游动阀游动阀
  1. 这种抽油泵采用等径柱塞,上游动阀罩内无阀球,仅通过螺纹与柱塞上部连接;

    The pump adopts isodiametric plunger , and there is no valve ball in its upper traveling valve housing .

  2. 给出了抽油杆与油管、柱塞与衬套、抽油杆与液柱、油管与液柱以及流体通过游动阀时摩擦力的求解方法;

    The non-Newtonian flow characteristic of product liquid was considered at the same time , the calculation method of friction load was given , including pumping rod and tubing , plunger and sleeve , tubing and liquid column , the force produced by the liquid through the travelling valve .

  3. 这种抽油泵柱塞游动阀采用机械强制开启和关闭的结构,柱塞为等径光管、浮动结构,可防止发生气锁游动阀、阀球关闭滞后、砂卡柱塞现象。

    The travelling valve of the pump is designed to be closed and opened forcibly , and the pump plunger adopts equal-diameter bare pipe with a floating structure to prevent gas lock and sand sticking .
