螺耐斯环保设备公司(多图)-匀壁厚定子

单螺杆泵问世一百多年来，定子和转子的演变更新换代有多种设计，匀壁厚定子，但常规占比90%的定子的设计制造都是特定的金属中空柱形模具里形成的内壁不等厚度橡胶材料，外壁为等厚度金属碳钢管组成的零件，但是该种结构输送介质时定子承受压力有限，适用范围有限。

本新型采用的技术方案如下：一种单螺杆泵等壁厚定子注塑模具，包括螺旋形定子成型芯棒，还包括与其配套使用设有注胶孔的螺旋形定子金属管，所述螺旋形定子成型芯棒位于该螺旋形定子金属管中，两者之间间距各处均等，且共同固定于两端板之间形成密封的橡胶注塑腔。

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.

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.
