Abstract

本发明涉及机械采油的金属定子螺杆泵。解决了橡胶定子作内衬时，螺杆泵启动困难、工作效率低的问题。其特征在于：将定子3改为金属材质制品，转子1外壁挂一层尼龙6；金属材质的转子1可用尼龙材质制品替代。使得螺杆泵工作时不存在溶胀的问题，螺杆泵也不易损坏，节省资金。

Description

金属定子螺杆泵
本发明涉及机械采油领域所用的一种采油设备，属于金属定子螺杆泵。
目前，有些油田使用螺杆泵进行地面注入聚合物或者用于井下抽油，但螺杆泵的定子都是用橡胶作内衬，其转子是用金属制作的。由于橡胶制品对于气体、聚合物液体泡沫及石油的反应比较灵敏，因此当螺杆泵工作时，其定子有不同程度的溶胀(有时溶胀为负值)，这样一来带来两个困难：一是溶胀过大，会造成扭矩过大，螺杆泵启动困难；二是溶胀过小，又会造成螺杆泵工作效率降低。况且橡胶还容易老化、脱胶等。从而将螺杆泵起出更换定子，造成资金浪费，影响生产。
本发明的目的在于克服上述技术的不足而提供一种无需更换定子而且提高螺杆泵工作效率的金属定子螺杆泵。
本发明的目的可以通过以下技术方案来达到：该螺杆泵包括金属材质的转子、定子、上下接头及定位销子，其特征是所述的定子为金属材质制品，转子外壁挂一层尼龙。
上述的金属材质的转子可用尼龙材质制品替代。
本发明较之上述现有技术具有如下优点：由于螺杆泵定子从橡胶材质改为金属材质制品，同时将转子外壁挂一层尼龙或完全用尼龙材质替代，从而使螺杆泵工作时不存在溶胀的问题，螺杆泵也不易损坏，节省资金。
附图1是本发明的结构剖视图。
下面结合附图将对本发明作进一步的说明：
该螺杆泵包括金属材质的转子1、定子3、上下接头(2,5)及定位销子4，定子3为金属材质制品，转子1外壁挂一层尼龙6或将金属材质的转子1用尼龙材质制品替代。从而使螺杆泵工作时不存在溶胀的问题，螺杆泵也不易损坏，节省资金。
实际安装和使用与常规螺杆泵完全一样。
