Submersible sewage slurry pump of fixed and mobile<3>
5, screw centrifugal impeller: the impeller blades for twisted spiral blades, wheel body on the cone from the suction along the axial elongation. The type of the slurry pump impeller and slurry pump and centrifugal slurry pump with a volume effect, through the suspended particles in the leaves, do not hit any part of the slurry pump, it is good non-destructive. The small damage to the carrier material. Due to the promotion of the role of helix, suspended particles through strong, so use the type of impeller suitable for slurry pumping large particles and long fibers containing medium, and the high concentration of medium. In the strict requirements of occasions to the conveying medium damage has obvious characteristic.
From the performance of speaking, the slurry pump head curve with the steep drop, power curve is relatively flat.
The pressurized water chamber submersible sewage slurry pump is the most common volute, built-in radial diffuser or channel using a submersible slurry pump in guide vane. Scroll a spiral, ring and intermediate type three. Spiral shaped volute basically not in sewage slurry pump. Annular pressure water chamber as a simple structure and convenient use in a small sewage slurry pump more. But because the intermediary (semi spiral) water pressure chamber of pressurized water chamber ring the application becomes smaller and smaller. Because of high efficiency and an intermediate type pressurized water chamber and a spiral pressure chamber of the high permeability of water. Has been more and more attention by the manufacturer.
