What is a single screw pump？

A single screw pump belongs to a positive displacement pump, which relies on the interference fit between the eccentric rotor and the fixed stator to form a sealed chamber that is not connected to each other. Through the rotation of the rotor inside the stator, the sealed chamber moves axially from the inlet end to the outlet end of the pump, thereby achieving continuous delivery of the medium in the sealed chamber.
characteristic:
1. Good self-priming ability, using water as the medium, the suction height can reach 3-5 meters.
2. It can transport liquids containing solid particles, with a solid content of up to 40% by volume. When the solid in the medium is powder particles, it can reach up to 60% or higher.
3. It can transport media of various viscosities, with a viscosity of 1000000CP.
4. It can transport media of various temperatures, with a temperature range from -20 ℃ to+180 ℃.
5. The flow rate and speed of the pump are approximately proportional, making flow regulation convenient. It can also be used as a metering pump, with a metering accuracy of up to ± 1%.
6. The conveying is smooth without agitation, with uniform liquid volume, low vibration, and low noise.
7. The pump has high efficiency, with a volumetric efficiency of up to 90% and a mechanical efficiency of up to 80%.
8. The structure is simple and easy to assemble, disassemble, and maintain.
Application areas:
The structure and characteristics of a single screw pump determine that it is suitable for conveying complex media containing solid particles, viscous, corrosive, shear sensitive, gas and fiber-containing, as well as various harsh working conditions at different temperatures.
