弹性密封水平井抽油泵
简 介：
弹性密封水平井抽油泵采用整体多级密封结构，各级之间相互独立，并强开强闭，具有防气功能；取消了游动阀，单级密封单元采用非接触式弹性间隙密封，该结构不仅能够减小密封间隙，降低漏失量，提高泵效，而且通过将普通泵柱塞与泵筒之间的硬性间隙变为弹性间隙，避免了卡泵，并可以避免砂粒对泵筒及柱塞表面的损伤，延长检泵周期；固定阀罩设有导向筋，在弹簧和推杆的作用下，阀球强制关闭。
该泵适用于出砂油井、大斜度井、水平井、高含气油井、稠油井、蒸汽吞吐井、蒸汽驱井、深井等多种类型的油井。
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.
