匀壁厚定子-武汉螺耐斯

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，匀壁厚定子，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.

建立了螺杆泵采油系统优化设计模型和杆柱扶正器优化设计模型，确定了杆柱扶正器合理布置方式，使螺杆泵系统能够保持长期运行，有效防止杆管偏磨。通过对定子橡胶与不同举升介质的适应性研究，使定子橡胶更具有针对性和目的性，研究确定了螺杆泵定子橡胶的检测和评定方法，以及合理过盈量的选择原则。

通过对螺杆泵定子结构及参数的优化设计，开发了等壁厚定子螺杆泵，解决了常规螺杆泵定子受力、散热和溶胀不均匀等技术不足;在现场应用中充分表现出了泵效高、系统的特点，显示了良好的工作性能。螺杆泵采油配套技术是保证油井正常生产、提高油井运转时率和检泵周期、实现有效举升的不可缺少的辅助技术措施，本文在螺杆泵采油系统优化设计的理论基础上，对防偏磨等配套技术进行了试验研究。

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.
