Twin-screw pump can replace the screw sleeve separately to reduce the cost of use. The material of the spiral sleeve can be chosen in many ways, which is suitable for different media and working conditions. The performance parameters of the same pump can be changed only by replacing the spiral sleeve (changing the lead) to adapt to the changing working conditions.
Spiral sleeve can be flexible through special treatment (surface hardening, spraying treatment, etc.) process to meet the requirements of special working conditions for the pump, and facilitate the repair of pumping components
Screw pump is a volumetric rotor pump, was born in 1931. Because of its unique structure, self-priming ability, high efficiency, small size, reliable operation, and the ability to transport a wide range of viscous media, screw pumps are widely used in petrochemical, shipping, power, mechanical and hydraulic systems, food, paper, sewage treatment and other industrial sectors.
As an energy-saving and material-saving product, screw pump has been widely used in China, and its demand has been increasing year by year, which has attracted more and more attention. Although there is still a gap between domestic screw pumps and foreign professional companies, with the increasing investment of scientific research and application practice of screw pumps in China, screw pumps will achieve good results in replacing the traditional technology and achieve energy-saving and material-saving benefits.
