Its function is to transfer power and write the stator to form a seal cavity.C、回轉筒C, rotary barrel回轉筒也就是一根內徑較大的油管或空心定子筒,接在定子的上部以給轉子和抽油桿桿柱以較大的回旋空間,防止轉子和抽油桿因偏心運動磨擦磨損油管。A rotary cylinder is also an oil tube or hollow stator barrel with larger inner diameter. It is co
nnected to the upper part of the stator to provide larger swirl space for the rotor and sucker rod string, so as to pvent the rotor and sucker rod from attrition wear due to eccentric wear.

單螺桿泵有以下優點:
1)因為泵內的回轉部件慣性力較低,故可使用很高的轉速;
2)結構堅實,安裝保養容易;
3)單螺桿泵的壓力和流量范圍寬闊。壓力約在3.4-340千克力/cm2,流量可達18600cm3/分;
4)單螺桿泵的吸入性能好,具有自吸能力;
5)與其它回轉泵相比,對進入的氣體和污物不太敏感;
6)流量均勻連續,振動小,噪音低;
7)單螺桿泵的運送液體的種類和粘度范圍寬廣。
單螺桿泵的缺點是,螺桿的加工和裝配要求較高;泵的性能對液體的粘度變化比較敏感。

單螺桿泵類別: 泵從大類分為兩種:容積泵和流量泵。 容積泵:通過泵的傳動部件形成的空腔轉運流體,傳動部件的轉動移出流體分為往復式和旋轉式兩大類 流量泵:帶給流體動能,流體轉運和循環;不允許干運行,液面以下運轉單螺桿泵特點: 1、在低轉速工況下壓力穩定 2、低必須氣蝕余量 3、可輸送含大顆粒的介質 4、可輸送含磨蝕性的介質 5、壓力可至48B 6、流量穩定、可用于計量加藥 7、流量對介質的粘度高低影響不大 8、只有一處軸封、便于檢修
