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 and thin rubber layer is with good anti-deforming

capability in the operation process of the equipment, so screw pump of the

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

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

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

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

improve pump usability.

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.
