The Improvement of The Structural Design Of The Spiral Centrifugal Pump

Regarding the screw centrifugal pump, most domestic manufacturers now produce submersible screw pumps, that is, the impeller is improved on the basis of the open impeller of the submersible sewage pump. Most of the applications are used for submersible sewage in sewage treatment. On the basis of the original, the YPLX screw centrifugal pump has made further technical improvements to the pump, and adopts the shaft-connected connection method, which has a wider application range.

The screw centrifugal pump was successfully researched by the Peruvian country in the 1960s. It was originally used for fishing shrimp, and then used for conveying solid-liquid mixing; two-phase flow can also be used for drainage and conveying of high mixing ratio and not too viscous liquid, for To prevent solid matter from clogging the conveying medium and make it flow out smoothly, there is a twisted helical blade in the impeller, which is extended axially from the suction port on the conical hub body, and the radius of the blade gradually increases to form a helical fluid channel. The casing is composed of two parts, the conical suction cover and the volute. Suction cover part of the impeller. Like a propeller, it produces helical propulsion. The impeller of the volute part produces centrifugal action like a general centrifugal pump. The acute angle part of the blade inlet guides the debris near the axis, and then uses the helical action to push it along the axis. This kind of combination like positive displacement pump and centrifugal pump is called screw centrifugal pump.
