1.The utility model is by being optimized centrifugal pump splitterr vanes structure, the jet-wake structure of runner inside is improved, it is more stable that flowing in runner becomes, and decreases the wild effects such as flow separation in runner and Secondary Flow, thus improve the combination property of centrifugal pump.
Description
Technical field
The utility model belongs to turbomachine field, relates to centrifugal pump, is specifically related to a kind of centrifugal pump splitterr vanes impeller.
Background technique
Centrifugal pump, as one of topmost power plant in the present age, is widely used in the sophisticated technology field such as all departments and Aero-Space of national economy.Improve the efficiency of centrifugal pump, can finite energy resource be made full use of, the economic benefit of raising.Therefore, improve research and the design level of centrifugal pump, have important impact to the national economic development, energy saving and environmental protection.Turbomachine mainly refers to the working machine adopting liquid as medium, mainly centrifugal pump.Pump is the one of turbomachine, is also the universal machine applied widely, and, just there is the work of pump in every field having flow of fluid.Along with the development of science and technology, the application of pump expands rapidly, and according to country variant statistics, the power consumption of pump all accounts for 1/5 of various countries' gross generation, and the power consumption of visible pump is huge, thus improves pump technical merit significant to energy saving.
Splitterr vanes (also known as short blade or small leaf) design method have employed long and short spacing with blades and arranges, effectively can improve the distribution of impeller flow field, improve impeller pressure ratio, improve the stability run.Reasonable interpolation splitterr vanes effectively can improve the jet-wake structure of runner exit, and lift can be significantly improved, and reduce disc friction, reach the object of raising the efficiency.The design of splitterr vanes needs to consider the factors such as the biased degree of splitterr vanes inlet diameter, splitterr vanes and splitterr vanes angle of yaw.Stream vane inlet diameter is directly connected to the action length of splitterr vanes, oversizely can block impeller inlet, does not reach and requires range of flow, and too short not having is improved impeller outlet jet-wake structure, improved the effects such as efficiency of centrifugal pump.Therefore the stability run centrifugal pump of the position of splitterr vanes inlet diameter and overall performance have important impact.
Summary of the invention
The purpose of this utility model is the deficiency for existing research, a kind of centrifugal pump splitterr vanes impeller is provided, the jet-wake structure of runner inside is significantly improved, it is more stable that flowing in runner becomes, effectively decrease the wild effect such as flow separation and Secondary Flow in runner, centrifugal lift of pump and efficiency are also improved, thus improve the combination property of centrifugal pump.
A kind of centrifugal pump splitterr vanes of the utility model impeller, comprise blade and back shroud of impeller, blade is arranged on back shroud of impeller, described blade comprises four linear leafs and four short blades, four described linear leaf circumference equidistantly distributions, four short blade circumference equidistantly distributions, and short blade is positioned at the middle of adjacent two linear leafs composition runner, described short blade inlet diameter D

the beneficial effects of the utility model
The utility model is by being optimized centrifugal pump splitterr vanes structure, the jet-wake structure of runner inside is improved, it is more stable that flowing in runner becomes, and decreases the wild effects such as flow separation in runner and Secondary Flow, thus improve the combination property of centrifugal pump.
Accompanying drawing explanation
Fig. 1 is sectional drawing of the present utility model.
Description of reference numerals: comprise linear leaf 1, short blade 2.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, a kind of centrifugal pump splitterr vanes blade wheel structure comprises 4 linear leafs, 4 short blades and back shroud of impeller, and its section sectional drawing (only shows a runner herein) as shown in Figure 1, comprises linear leaf 1 and short blade 2.Impeller outlet diameter is D
1, short blade 2 inlet diameter is D
2=0.7D
1.Impeller outlet diameter D
1=470mm, short blade 2 inlet diameter calculated by above relation is D
2=329mm.
This centrifugal pump splitterr vanes structure can make the jet-wake structure of runner inside improve, and it is stable that the flowing in runner becomes, the wild effects such as the flow separation in minimizing runner and Secondary Flow, thus improves the combination property of centrifugal pump.
