匀壁厚定子-螺耐斯设备

等壁厚定子优势：

advantages of stator with equal wall

thickness:

1.等壁厚定子是橡胶层薄而均匀，可以---螺杆泵运行时的散热效果，不会产生热---效应，而温度是影响定子寿命的敏感元素之一，等壁厚定子因有---的散热性能可以减缓橡胶的热老化，从而使用寿命比常规泵长。

1. rubber layer of the stator with equal wall thickness is

thin&uniform which can improve the heat 1dissipation effect when the screw

pump operates&no thermal aggregation effect is produced. the temperature is

one of sensitive elements affecting lifetime of the stator. the stator with

equal wall thickness can slow down thermal ageing of the rubber because it has

good heat 1dispersion，匀壁厚定子， as a result， its service life is longer than that of

conventional pump.

螺杆泵原理

       对于采油螺杆泵来说，沿着螺杆泵的全长，在转子外表面与定子橡胶衬套内表面间形成多个密封腔室；随着转子的转动，在吸入端转子与定子密封衬套内表面间会不断形成密封腔室，并向排出端推移，后在排出端消失，油液在吸入端压差的作用下被吸入，并由吸入端推挤到排出端，压力不断升高，流量非常均匀。螺杆泵工作的过程本质上也就是密封腔室不断形成、推移和消失的过程。
