Description

双冲程式抽油泵
本实用新型属于采油设备技术领域,特别涉及一种抽油泵的改进。
目前,在开采石油的抽油过程中,均采用抽油杆带动深井柱塞泵进行抽油,这种抽油泵在使用中,存在着柱塞泵上、下往复一次只能排一次油,效率较低;同时,柱塞采油泵还存在着材料与结构不合理、防砂效果不理想等问题。
本实用新型的目的是提供一种上、下往复一次可排两次油的双冲程式抽油泵。
本实用新型结构原理如下:
该抽油泵由泵筒6组成,在泵筒6内有圆管形柱塞3,泵筒6内与柱塞4外形成一侧腔11,柱塞3内形成一内腔10,在柱塞3下面的泵筒底部固定有一凡尔罩7,下凡尔2在凡尔罩7内,在凡尔罩7上有出油孔12,在泵筒6壁的侧腔上部开有2-6个进油孔,在每个进油孔上固定有单向阀门5,在单向阀门5的内腔位置上面有小凡尔4,在泵筒6顶端有侧腔的出油口8,柱塞3顶端有上凡尔1,柱塞3顶端与抽油杆连接固定,并且有侧孔通入输油管。
本实用新型的优点是:该抽油泵出油率高、效益好,磕头机上下运动双冲程活塞泵都出油,比柱塞泵多出油30%-50%,结构简单、造价低,因去掉了柱塞泵衬套加工要求高的弱点,所以成本下降。
图1是双冲程式抽油泵剖视图。
其中:1是上凡尔、2是下凡尔、3是柱塞、4是小凡尔、5是单向阀门、6是泵筒、7是凡尔罩、8是出油口、9是出油孔、10是内腔、11是侧腔。
柱塞的下部与泵筒的内壁密封滑动配合,这样就形成了侧腔,侧腔及单向阀门和小凡尔构成付泵,柱塞中的内腔及上、下凡尔构成主泵,当柱塞相对泵筒上行时,内腔形成负压,下凡尔打开,上凡尔关闭,油从下凡尔下面流入内腔,此时侧腔形成正压,单向阀门关闭,小凡尔打开,侧腔的油从小凡尔顺着出油口进入输油管,当柱塞相对泵筒下行时,内腔形成正压,下凡尔关闭,上凡尔打开,油从上凡尔流入输油管,此时,侧腔形成负压,单向阀门打开,小凡尔关闭,侧腔的油从单向阀门进入侧腔,如此住复,只要柱塞相对泵筒上行或下行运动都能抽油。
