匀壁厚定子-螺耐斯(商家)

2.均匀并且薄的橡胶层在设备运行过程中抗变形能力好，因而等壁厚定子螺杆泵单级承受的压力高，在相同工况运行下，可以减少泵的级别和定转子之前过盈的配合量，同时运转扭矩和系统于常规泵型，从而提高泵的使用性能。

2. uniform&thin rubber layer is with good anti-deforming

capability in the operation process of the equipment，匀壁厚定子， so screw pump of the

stator with equal wall thickness bears high pressure based on1 single stage

which can reduce pump level&previous excess suitable quantity of stator and

rotor in case of operation under the same operating condition&operating

torque&system efficiency are higher than those of conventional pump to

improve pump usability.

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。
