Description

一种抽油泵柱塞上罩断裂及上凡尔下移装置
技术领域
本实用新型涉及一种油田井下抽油泵柱塞结构的研究与改进,具体涉及一种抽油泵柱塞上罩断裂及上凡尔下移装置。
背景技术
目前随着油田勘探开发的不断深入,原油开采的难度越来越大,油井的动液面也越来越深,抽油泵的下泵深度也随着不断加深,抽油泵上罩不但要经受井下高温高压及有害物质的侵害,而且柱塞上凡尔对上罩的冲击、磨损也更加严重。抽油泵柱塞上罩断裂的现象时有发生,直接影响了油井的检泵周期。
发明内容
为解决现有技术的不足,本实用新型提供一种抽油泵柱塞上罩断裂及上凡尔下移装置。
本实用新型所采取的技术方案是:一种抽油泵柱塞上罩断裂及上凡尔下移装置,由上罩、柱塞总成、上凡尔、下凡尔、泵筒总成组成,上罩的两侧设有柱塞总成,柱塞总成的两侧设有泵筒总成,柱塞总成内设有上凡尔和下凡尔,上凡尔和下凡尔并联在一起。
本实用新型的有益效果是:结构简单,安装方便,适用油田各种抽油泵。
附图说明
附图1为本实用新型的结构示意图。
其中:1上罩、2柱塞总成、3上凡尔、4下凡尔、5泵筒总成。
具体实施方式
下面结合附图对本实用新型作进一步说明。
如图所示,一种抽油泵柱塞上罩断裂及上凡尔下移装置,由上罩1、柱塞总成2、上凡尔3、下凡尔4、泵筒总成5组成,上罩1的两侧设有柱塞总成2,柱塞总成2的两侧设有泵筒总成5,柱塞总成2内设有上凡尔3和下凡尔4,上凡尔3和下凡尔4并联在一起。
