Its function is to transfer power and write the stator to form a seal cavity.C、回转筒C, rotary barrel回转筒也就是一根内径较大的油管或空心定子筒,接在定子的上部以给转子和抽油杆杆柱以较大的回旋空间,防止转子和抽油杆因偏心运动磨擦磨损油管。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 prevent the rotor and sucker rod from attrition wear due to eccentric wear.
单螺杆泵有以下优点:
1)因为泵内的回转部件惯性力较低,故可使用很高的转速;
2)结构坚实,安装保养容易;
3)单螺杆泵的压力和流量范围宽阔。压力约在3.4-340千克力/cm2,流量可达18600cm3/分;
4)单螺杆泵的吸入性能好,具有自吸能力;
5)与其它回转泵相比,对进入的气体和污物不太敏感;
6)流量均匀连续,振动小,噪音低;
7)单螺杆泵的运送液体的种类和粘度范围宽广。
单螺杆泵的缺点是,螺杆的加工和装配要求较高;泵的性能对液体的粘度变化比较敏感。
单螺杆泵类别:泵从大类分为两种:容积泵和流量泵。容积泵:通过泵的传动部件形成的空腔转运流体,传动部件的转动移出流体分为往复式和旋转式两大类流量泵:带给流体动能,流体转运和循环;不允许干运行,液面以下运转单螺杆泵特点:1、在低转速工况下压力稳定2、低必须气蚀余量3、可输送含大颗粒的介质4、可输送含磨蚀性的介质5、压力可至48B 6、流量稳定、可用于计量加药7、流量对介质的粘度高低影响不大8、只有一处轴封、便于检修
