Analysis on the medium adaptability of screw pump
Screw pump is a pump product that ensures that the medium rises in an axial spiral shape by the rotation of the spiral blade. Its medium adaptability analysis can be carried out from the following aspects:
1. Applicable medium range
Screw pumps can transport a wide range of media, including but not limited to the following:
High viscosity liquid: Screw pumps are suitable for transporting high viscosity liquids, such as various lubricating oils, oil-coal slurries, water-coal slurries, etc.
Liquids containing solid particles: Screw pumps can pump liquids containing certain solid particles, such as mining water, floating liquid, drilling mud, coal slime, etc. However, it should be noted that the content and particle size of solid particles should be within the allowable range of the screw pump.
Corrosive liquid: Screw pumps also have a certain adaptability to certain corrosive liquids, but it is necessary to select appropriate pump bodies and sealing materials according to the corrosiveness of the medium.
Easily gasifiable liquids: Screw pumps are also suitable for transporting easily gasifiable liquids, such as some light hydrocarbon liquids.
2. Medium adaptability characteristics
Stable pressure and uniform flow: When the screw pump is working, the pressure is stable and the flow is relatively uniform, which makes it suitable for occasions that require stable flow and pressure delivery.
Strong self-priming ability: The screw pump has a strong self-priming ability and can easily achieve self-priming and conveying of the medium.
Variable adjustment performance: The screw pump has good variable adjustment performance, and can adjust the flow and pressure as needed to achieve multiple uses of one pump.
Not easy to block: Due to the structural characteristics of the screw pump, it is not easy to produce abnormal blockage and is suitable for conveying liquids containing solid particles or fibers.
3. Applicable occasions
The medium adaptability of the screw pump makes it widely used in various industrial occasions, including but not limited to:
Mining industry: used to convey mining water, floating liquid, drilling mud, etc.
Chemical industry: used to convey various acid, alkali, salt liquids and paste chemical slurries, etc.
Ceramic industry: used to convey clay, clay, glaze, etc.
Shipbuilding industry: used to convey dirty oil, sewage, various fresh water, fuel oil, etc.
Sewage treatment: used to convey sludge, sewage, dirty oil and other media.
Energy industry: used to convey various water-coal slurries, fuel oil, oil-coal slurries, coal slime, etc.
Food, medicine, and cosmetics industries: used to transport various wines and wine troughs, fruit pulp, starch paste, ointment, mother liquor, potato mash and other media.
Papermaking industry: used to transport various coatings, cellulose pulp and other media.
