Abstract
To add the splitter blades is an important technique to improve the pump performance characteristics. The effects of splitter blade on the pump performance and flow characteristics in a high-speed ...
Highlights
The high-speed centrifugal pump is a blade-pump unit with compact structure and high pump head, which is widely used to pump oil or water in cutting-edge facilities such as aeroengine and petrochemical equipment
The heads of pump 2 have increased 10 m approximately on the operational conditions by comparing with pump 1, while the efficiencies have raised nearly 4%. These results favor the positive effect of splitter blade on the performance characteristics of the high-speed centrifugal pump
The effects of the splitter blade on the pump performance characteristics of a high-speed centrifugal pump were studied by the numerical simulations
Summary
The high-speed centrifugal pump is a blade-pump unit with compact structure and high pump head, which is widely used to pump oil or water in cutting-edge facilities such as aeroengine and petrochemical equipment. The design method of ‘‘splitter blade’’ is to design the impeller with short blades spaced within long blades, which can improve effectively the unsteady flow in the blade passage to raise the impeller performance and the operating stability of pump. Does this method improve the performance characteristics of the high-speed centrifugal pump, and has less effect on pump structure.
