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***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,莫诺,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。
A、定子A, stator定子是螺杆泵的一个关键部件,并直接影响到井下机组的寿命。定子制造质量越高,井下机组的寿命就越长。定子的作用就是提供转子工作和液体抽汲的螺旋腔,其结构非常简单,由钢制外壳和塑料/橡胶衬套内腔有双螺旋、三螺旋、四螺旋甚至五螺旋、六螺旋,在相同尺寸下,螺旋数越多,泵的排量越高。The stator is a key component of the screw pump, which directly affects the life of the downhole unit. The higher the quality of the stator, the longer the life of the downhole unit. The role is to provide a rotor stator and liquid pumping spiral c***ity drain, the structure is very simple, a steel shell and a plastic / rubber bushing c***ity with double helix, three helix, four or even five, six spiral helical spiral, in the same size, the number of spiral, the displacement of the pump is high.

B、转子B, rotors转子的结构也非常简单,主体是钢制杆件,一般外涂耐磨耐蚀的铬合金材料。其作用是传递动力和写定子形成密封腔。The structure of the rotor is also very simple, the main body is steel rod, generally coated with abrasion resistant and corrosion resistant chromium alloy material. Its function is to transfer power and write the stator to form a seal c***ity.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 connected 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.
