等壁厚定子優(yōu)勢：

Advantages of stator with equal wall

thickness:

1.等壁厚定子是橡膠層薄而均勻，可以改善螺桿泵運行時的散熱效果，不會產(chǎn)生熱聚集效應，而溫度是影響定子壽命的敏感元素之一，等壁厚定子因有良好的散熱性能可以減緩橡膠的熱老化，從而使用壽命比常規(guī)泵長。

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.等壁厚定子橡膠溶脹、溫脹均勻，能較好的保證泵的型線，泵的密封性能好，使用運轉(zhuǎn)時具有良好的力學性能，有利于長時間持續(xù)泵的，從而延長泵的使用周期。

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.

粘度適應范圍廣，可以舉升稠油。

適應高含砂井，在高含砂的情況下仍可以正常生產(chǎn)。

適應高含氣井，螺桿泵不會發(fā)生氣鎖，比較適合于油氣混輸。

適應海上油井叢式井組和水平井。

允許井口有較高回壓。

等壁厚的螺桿鉆具單級壓降要比常規(guī)螺桿鉆具提高 50%-，橡膠層的抗變形能力提高，相同壓力下，等壁厚定子橡膠層的變形量要遠小于常規(guī)定子橡膠層的變形量，轉(zhuǎn)子與橡膠層間只需較小的過盈量即可達到密封效果，大大提高了鉆具的輸出效率。
