Description

抽油杆加重组件
技术领域
本实用新型涉及一种抽油杆加重组件,属于抽油设备领域。
背景技术
抽油杆柱是由若干根抽油杆首尾相接而成,在抽油过程中,抽油杆柱上行时受被提升油和抽油杆自身重力而受拉,下行时受油液阻力而受压,抽油杆柱在这种拉压交变载荷下疲劳而失效,目前解决这一问题大多采用加重杆,但这种加重杆直径一般为31.45-41.28mm,对于稠油井加重效果不显著。
实用新型内容
根据以上现有技术中的不足,本实用新型要解决的技术问题是:提供一种加重效果好的抽油杆加重组件。
本实用新型所述的抽油杆加重组件,包括套筒件,套筒件为两个半圆筒状夹筒,夹筒横向设置凹槽,凹槽内设卡箍;
包括接箍件,接箍件为一中空圆筒,两端内圈加工有内螺纹,圆筒内部设铅杆,铅杆通过在圆筒内焊接固定片固定在圆筒内。
套筒件端部为锥形,可以减小油液阻力。
夹筒***设滑槽,方便油液中的砾石通过,避免积存在接箍件处,防止堵塞。
套筒件与接箍件表面加工淬火层,提高表面硬度,保证内部的机械性能。
工作原理及过程:
工作时,将套筒件夹在抽油杆中部,用卡箍固定,用接箍件通过螺纹将抽油杆连接起来,锥形的套筒件端部可以减小油液阻力,如果油液中有砾石,可以通过滑槽从套筒件侧壁上划过,减少套筒件的划伤,避免砾石的积存。
本实用新型与现有技术相比所具有的有益效果是:
本实用新型所述的抽油杆加重组件,通过套筒件和接箍件来增大抽油杆的整体重量,加重效果好,并且使用灵活,拆卸方便,锥形的套筒件端部可以减小油液阻力,套筒件侧壁上的滑槽可减少套筒件的划伤,避免砾石的积存。
附图说明
图1是本实用新型套筒件主视图;
图2是本实用新型套筒件俯视图;
图3是本实用新型接箍件示意图。
图中:1、夹筒;2、凹槽;3、滑槽;4、卡箍;5、圆筒;6、固定片;7、铅杆。
具体实施方式
下面结合附图对本实用新型的实施例做进一步描述:
如图1-图3所示,本实用新型所述的抽油杆加重组件,包括套筒件,套筒件为两个半圆筒状夹筒1,夹筒1横向设置凹槽2,凹槽2内设卡箍4;
包括接箍件,接箍件为一中空圆筒5,两端内圈加工有内螺纹,圆筒5内部设铅杆7,铅杆7通过在圆筒5内焊接固定片6固定在圆筒5内。
套筒件端部为锥形,可以减小油液阻力。
夹筒***设滑槽3,方便油液中的砾石通过,避免积存在接箍件处,防止堵塞。
套筒件与接箍件表面加工淬火层,提高表面硬度,保证内部的机械性能。
工作原理及过程:
工作时,将套筒件夹在抽油杆中部,用卡箍4固定,用接箍件通过螺纹将抽油杆连接起来,锥形的套筒件端部可以减小油液阻力,如果油液中有砾石,可以通过滑槽3从套筒件侧壁上划过,减少套筒件的划伤,避免砾石的积存。
