Research Status of Composite Impeller split case pump

There are three kinds of design methods of horizontal split case pump are from the efficiency, no overload, impeller and pump matching and other different research level, targeted, but there are also large limitations. The length and length of the composite blade design concept from the improvement of the internal flow field of the impeller, the pressure field, through the long leaves between the short blade flushing wake, effectively prevent the development of the production of the surplus, increase the limited leaf correction factor, thereby increasing Pump head, reduce the impeller diameter, can effectively improve the flow rate distribution, improve pump performance, according to the design concept of low-speed centrifugal pump designed in the actual project has been very good application.
