Abstract

本实用新型涉及石油开采机械，公开了一种自旋式抽油杆扶正器，扶正轴穿入扶正体内，扶正体的外表面设有泥浆槽，相邻泥浆槽之间形成的凸棱上设有轴向的滚柱槽，滚柱槽内设有轴向滚柱。本实用新型可避免油管内壁结垢造成堵塞；凸棱上的滚柱可使扶正器与油管内壁发生滑动摩擦，减小扶正器磨损速度，提高扶正器使用寿命。

Description

一种新型抽油杆扶正器
技术领域
本实用新型涉及一种扶正器，尤其为一种石油开采时使用到的新型抽油杆扶正器。
背景技术
在油田抽油系统中，为了减少抽油杆与油管之间发生摩擦，常在容易发生偏磨的杆段加装抽油杆扶正器，这样抽油杆与油管之间的滑动摩擦就转化成扶正器与油管之间的滑动摩擦或转动摩擦。目前油田使用的多种扶正器寿命普遍较短，究其原因是工作时扶正器外壁与油管内壁发生滑动摩擦，磨损严重，在油管内高温、泥沙等恶劣环境下磨损速度较快。
实用新型内容
为克服上述技术不足，本实用新型提供了一种结构新颖，寿命长的新型抽油杆扶正器。
为实现上述技术目的，本实用新型是采用以下技术方案实现的：一种自旋式抽油杆扶正器，扶正体为中空的柱形，扶正轴穿入扶正体内，其特征在于：扶正体的外表面设有轴向的弧形凹陷的泥浆槽，相邻泥浆槽之间形成的凸棱上设有轴向的滚柱槽，滚柱槽内设有轴向滚柱，滚柱槽两端设有限位挡片。
本实用新型具有以下有益效果：由于扶正体的外表面的泥浆槽呈轴向，油杆上下移动时，可对油管内介质进行扰动，避免油管内壁结垢造成堵塞；凸棱上的滚柱可使扶正器与油管内壁发生滑动摩擦，减小扶正器磨损速度，提高扶正器使用寿命。
附图说明
附图为本实用新型结构示意图。
图中，1、滚柱，2、泥浆槽，3、扶正体，4、限位挡片，5、扶正轴。
具体实施方式
参看附图，一种自旋式抽油杆扶正器，扶正体3为中空的柱形，扶正轴5穿入扶正体3内，其特征在于：扶正体3的外表面设有轴向的弧形凹陷的泥浆槽2，相邻泥浆槽2之间形成的凸棱上设有轴向的滚柱槽，滚柱槽内设有轴向滚柱1，滚柱槽两端设有限位挡片4。
