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，可以改善螺杆泵运行时的散热效果，不会产生热聚集效应，而温度是影响定子寿命的敏感元素之一，等壁厚定子因有良好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 and uniform which can improve the heat 1dissipation effect when the screw
pump operates and 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, as a result, its service life is longer than that of
conventional pump.
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.
单螺杆泵主要工作执行元件是由一对分别叫做定子和转子的零件组成：其中定子的形成是通过橡胶注塑机将加热到一定温度下而热熔后有流动性的橡胶注塑在一个特定的金属中空柱形模具里形成的内壁为不等厚度橡胶材料，而外壁为等厚度金属碳钢管组成的零件如图1所示；单螺杆泵的转子是通过加工机床切削加工而成的全金属异形杆件类零件，普通单螺杆泵的工作原理就是通过类似单头螺纹的金属转子和类似双头螺母的橡胶定子之间的过盈配合，将360度方向螺旋缠绕的各自密封的空腔里面的介质，随着转子的转动，沿转子轴线螺旋输送出去，而达到工作目的。
