Abstract:
The solid-liquid two-phase centrifugal pump is mainly used in coal-chemical industry, metallurgical industry, thermo power plant, petrochemical industry and municipal engineering to transport the medium with slag, solid impurities and slurry. Generally speaking, its lift is not more than 80 m. The high-pressure & high-lift centrifugal pump for solid-liquid phase mediums, whose lift is more than 80 m, can be used as chill water-pump and scrubber circulation pump in coal-gasification industry, and TA slurry feeding pump in PTA industry. More attention should be paid to some technical features in design of these pumps. In this article, some design philosophies of high-pressure & high-lift centrifugal pump for solid-liquid phase mediums are described in the aspects of rotor rigidity, axial force balancing, flow passage component's applicability, brace's stability and mechanical
