IMO screw pump It is a reverse pump that transports liquid or pressurizes it by changing and moving the volume of the meshing space formed by the pump body and the screw (see pump). Screw pump It is divided into single screw pump, twin screw pump and Three screw pump Etc.

When the driving screw tumbles, it drives the driven screw engaged with it to tumble together. The volume of screw engagement space at one end of the suction chamber gradually increases, and the pressure drops. The liquid enters the meshing space volume under the action of differential pressure. When the volume increases to large enough to form a sealing chamber,

The liquid moves axially in one sealing chamber after another until it is discharged from one end of the chamber. At this time, the volume of screw engagement space at one end of the discharge chamber gradually shrinks, and the liquid is discharged.

The stator of the screw pump is an important part of the screw pump, which is used in cooperation with the rotor of the screw pump. The screw pump has corrosion resistance and wear resistance, and has been widely used due to its wide media planning. What factors constitute the wear of screw pump stator?

Abrasive wear, wet abrasive wear is the existence of liquid medium between abrasive and rubber; Dry abrasive wear means that there is no liquid medium between abrasive and rubber. Abrasive wear is one of the main reasons for screw pump wear.

During the application of screw pump, the liquid flow between the rotor and stator of screw pump will also cause wear. After the screw pump has been used for a long time, the stator will be worn due to long-term scouring.

The idling of the screw pump will not only cause the wear of the screw pump stator, but also damage the equipment and affect the application function of the screw pump. The stator of the screw pump is a vulnerable part. Generally, enterprises should prepare more and check and replace them on time.
