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。
3.等壁厚定子橡胶溶胀、温胀均匀,能较好的保证泵的型线,泵的密封性能好,使用运转时具有良好的力学性能,有利于长时间持续泵的,从而延长泵的使用周期。
3. Rubber of stator with equal wall thickness is with even
swelling and thermal expansion which can well ensure molded lines of the pump.
The pump is with good sealing property as well as good mechanical property at
the moment of use and operation, making for continuous high efficiency of the
pump for a long time to prolong service cycle of the pump.
