Screw pump is a new type of pump according to the principle of rotary engagement volume type, its main working parts are eccentric screw (rotor) and fixed bushing (stator). Due to the special geometry of the stator and rotor,the formation of a separate sealed cavity, the medium is uniformly carried out in the axial flow, the internal flow rate is low, the volume remains the same, the pressure is stable, so there will be no eddy current and agitation.
In addition, the stator of the progressing cavity pump is made of a variety of elastic materials. Compared with thegeneral pump, it has obvious
advantages in the transportation of high viscosity fluid, medium containing hard suspended particles or medium containing fiber. Therefore, the progressing cavity pump is widely used in sand production Wells and heavy oil Wells.
The stator is a key component of progressing cavity pump and directly affects the life of downhole unit. The higher the stator quality, the longer the downhole unit life. The stator's role is to provide a helical cavity for rotor work and liquid pumping. Its structure is very simple, consisting of a steel casing and plastic/rubber bushing
