Description

一种井下抽油泵液压驱动装置
技术领域
本实用新型属于泵领域,涉及一种井下抽油泵液压驱动装置。
背景技术
现有的采油技术中,各油田使用的普通抽油泵,泵效低,采油成本高。
本发明就是针对上述不足情况,结合各种采油技术的优点,设计制造出的一种新型的井下抽油泵液压驱动装置。本发明由于不用地面抽油机和抽油杆,解决了杆管偏磨问题,节约了大量钢材,使采油成本大大降低,即经济又环保,具有广阔的发展前景。
实用新型内容
本实用新型是这样实现的:一种井下抽油泵液压驱动装置,包括油柜、细长型电动机、油泵、行程换向阀、液压缸和活塞;其特征在于,该装置放置在油井内的油管底部。
与现有技术相比,本实用新型具有的效果和益处是由于取消了传统采油的抽油机和抽油杆,减少了大量的钢材消耗,解决了抽油杆与油管偏磨造成油管报废问题,节约了采油成本,降低了能耗,节省了维修成本,前景广阔。
附图说明

具体实施方式
下面结合附图详细说明本实用新型的具体实施方式。
电动机3带动液压油泵4旋转,液压油从油柜2经吸入管路吸入到液压油泵4中,活塞从A侧到B侧运动时,行程换向阀5、行程换向阀9打开,行程换向阀8、行程换向阀10关闭,液压油泵4泵出的高压油进入到活塞A侧,活塞B侧的油液通过行程换向阀9输回油柜2中,A、B两侧存在压差,推动活塞7运动,完成一个冲程。到达冲程终点时,行程换向阀5、行程换向阀9关闭,行程换向阀8、行程换向阀10打开,高压油液进入到活塞B侧,活塞A侧的油液通过行程换向阀10输回油柜2中,A、B两侧存在压差,推动活塞7反向运动,完成一个反冲程。周而复始,实现了活塞7在液缸6中的往复运动,活塞带动抽油泵的抽油杆实现了抽油泵的驱动。
