Abstract

本实用新型涉及油田抽油机井与泵活塞之间的连杆,提高了连杆的承载面积和机械性能,不易断裂。它使H级钢材的连杆2直接与泵活塞上接头1用M18×15的螺纹连接,增加了螺纹的外径,去掉了中间的背帽,使承载面积增加,受力平衡,改善了机械性能。

Description

抽油机井抽油杆与泵活塞之间的连杆
本实用新型涉及抽油机井抽油杆与泵活塞之间的连杆。
油田抽油机井,用抽油杆与井下活塞泵上活塞杆之间通过连杆连接做上下往复抽油运动。其中连杆有Φ32、Φ38两种,抽油杆是Φ19,连接丝扣为M16×15、之间采用背帽锁紧。由于之间采用背帽连接,往往由于安装原因,受力不均,连杆极易断裂,影响抽油泵的正常生产。
本实用新型的目的在于避免上述目前技术中存在的不足之处,而提供一种不易断裂高强度的抽油机井抽油杆与泵活塞之间的连杆。
本实用新型的目的可以通过以下技术方案来达到:采用H级连杆直接与原活塞上出油M18×15接头连接,二连接端面相触及。之间把背帽去掉,连接后受力平衡,可达到本目的。
本实用新型与上述目前技术相比较可具有如下效果:由于连杆直接与泵塞上M18×15接头连接,增加了横截面积,受力平衡,提高了强度,不易断裂。
附图是本实用新型示意图。
下面结合附图将对本实用新型作进一步的说明:
由附图所示,连杆2有上、下接头,上接头与抽油杆连接;下接头与泵塞上接头1连接,之间用背帽锁紧;连杆2中部是变形体。本实用新型是用H级钢材的连杆2直接与泵塞上接头1连接,上接头1是M18×15的螺纹接头。去掉了中间的背帽,有效的提高了承截面积和机械性能。
