彈性密封水平井抽油泵
簡??介：?彈性密封水平井抽油泵采用整體多級密封結構，各級之間相互獨立，并強開強閉，具有防氣功能；取消了游動閥，單級密封單元采用非接觸式彈性間隙密封，該結構不僅能夠減小密封間隙，降低漏失量，提高泵效，而且通過將普通泵柱塞與泵筒之間的硬性間隙變為彈性間隙，避免了卡泵，并可以避免砂粒對泵筒及柱塞表面的損傷，延長檢泵周期；固定閥罩設有導向筋，在彈簧和推桿的作用下，閥球強制關閉。?該泵適用于出砂油井、大斜

彈性密封水平井抽油泵
簡 介：
彈性密封水平井抽油泵采用整體多級密封結構，各級之間相互獨立，并強開強閉，具有防氣功能；取消了游動閥，單級密封單元采用非接觸式彈性間隙密封，該結構不僅能夠減小密封間隙，降低漏失量，提高泵效，而且通過將普通泵柱塞與泵筒之間的硬性間隙變為彈性間隙，避免了卡泵，并可以避免砂粒對泵筒及柱塞表面的損傷，延長檢泵周期；固定閥罩設有導向筋，在彈簧和推桿的作用下，閥球強制關閉。
該泵適用于出砂油井、大斜度井、水平井、高含氣油井、稠油井、蒸汽吞吐井、蒸汽驅井、深井等多種類型的油井。
The pump applies the multistage sealing structure, independent each other at all levels, and strong on strong off, has the anti-gas function; Cancel the traveling valve, single stage seal unit adopts non-contact elastic clearance seal, this structure can not only decrease the seal clearance, reduce loss, improve the pump efficiency, and change the rigid clearance between ordinary pump plunger and pump barrel into elastic clearance, to avoid the pump stuck, and can avoid sand damage on the surface of the pump barrel and plunger, prolong the pump inspection cycle; The standing cage is equipped with guide baffle, and under the action of the push rod and the spring, the valve ball is forced to shut down.
The pump is suitable for various types of wells such as sand production wells, high deviated wells, horizontal wells, high gas wells, heavy oil and steam stimulation wells, steam drive wells, deep wells etc.
