Abstract
The utility model relates to a low specific speed impeller. The low specific speed impeller is characterized in that: the outlet edges of the low specific speed impeller form a polygon taking the outermost points of blades as vertexes. The low specific speed impeller has the advantage of effectively reducing the contact area of a disc and a fluid so as to effectively reduce the abrasion loss, improve the efficiency, fulfill the purposes of high efficiency and energy conservation and solve the problems of low efficiency and high energy consumption of a low specific speed pump.
Description
Technical field
The utility model relates to a kind of low-specific-speed impeller.
Background technique
The impeller outlet limit of conventional low-specific-speed impeller is circular, when pump working, current are after the impeller blade supercharging, again when come out in the impeller outlet limit, because the impeller outlet limit is circular, therefore current at a high speed and impeller outlet limit produce friction, and this moment, the disc friction losses of water pump was big, and the efficient of water pump is low.So the impeller outlet limit of demanding improvement low-specific-speed impeller urgently, to solve the problems referred to above that the low-specific-speed impeller exists.
Summary of the invention:
The purpose of this utility model is that the impeller outlet limit that solves low-specific-speed impeller conventional in the prior art adopts the disc friction losses of circular existing water pump big, and the problem that pump efficiency is low provides a kind of low-specific-speed impeller.The utility model designs a kind of low-specific-speed impeller, comprises the low-specific-speed impeller, it is characterized in that: the outlet limit of low-specific-speed impeller is for being the polygonal on summit with each blade outermost point.The utility model has the advantages that the area that effective minimizing disk contacts with fluid, thereby effectively reduce friction loss, raise the efficiency, realize energy-efficient purpose, solve and trouble the difficult problem that the low-specific-speed pump efficiency is low, energy consumption is big always.
Description of drawings:
Fig. 1 is the prior art constructions schematic representation,
Fig. 2 is a structural representation of the present utility model,
Below in conjunction with accompanying drawing and construction embodiment the utility model is made detailed operation instruction.
Embodiment:
Comprise low-specific-speed impeller 1 among the figure, it is characterized in that: the outlet limit of low-specific-speed impeller 2 is for being the polygonal on summit with each blade 3 outermost point.Because the outlet limit of low-specific-speed impeller is for being the polygonal on summit with each blade outermost point, therefore by the high-velocity flow after the blade supercharging when the low-specific-speed impeller throws away, want that with the outlet limit of low-specific-speed impeller the area that contacts significantly reduces, the area that effective outlet limit of reducing the low-specific-speed impeller contacts with fluid, thereby effectively reduce friction loss, raise the efficiency, realize energy-efficient purpose, solve and trouble the difficult problem that the low-specific-speed pump efficiency is low, energy consumption is big always.
