Abstract
The utility model discloses a semi -open impeller, include: wheel hub and edge circumference evenly distributed are in a plurality of blades of a wheel hub side surface, wherein, the blade is hollow cavity and welding on wheel hub's surface, and wheel hub between adjacent blade equipartition on the surface has a water conservancy diversion strip the oriented protruding tiny granule of equipartition on the lateral wall of blade for increase and fluidic frictional force, the utility model discloses bellied tiny particle and the water conservancy diversion strip of will making progress combines together, increases impeller and fluidic frictional force, and simultaneously, the blade is hollow cavity, reduces the weight of impeller, reduces centrifugal pump's mechanical loss.
Description
Technical field
The utility model belongs to mechanical field, relates in particular to a kind of half-opened impeller.
Background technology
Impeller all will be used large flow, high-lift and high efficiency in the liquid course of conveying of high-floor feedwater, high building fire-proofPump, and one of vitals that determines pump performance is exactly impeller. Centrifugal water pump is in the time of work, due to impeller and fluidThere is friction and produce rotation, mechanical energy is converted into kinetic energy, and then make water pump produce flow and lift. In prior art,The measure that increases centrifugal pump lift size is the diameter that increases impeller, or increases the number of impeller, namely so-called manyLevel pump. But the problem that can produce so is again, in the time increasing the diameter of impeller, can obviously increase mechanical loss of energy,And then the generation of reduction kinetic energy, make centrifugal water pump Efficiency Decreasing. When increasing the number of impeller, directly impact is centrifugalThe complexity of formula water pump structure, because every primary pump all can produce certain energy loss, so gross efficiency can significantly be fallenLow.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of half-opened impeller, this half-opened impeller energyCan increase centrifugal pump lift.
The purpose of this utility model is achieved by following technical proposals.
A kind of half-opened impeller, comprising: wheel hub and be distributed in multiple blades of described wheel hub one side surface along even circumferential,Wherein, described blade is hollow cavity the surface that is welded on wheel hub, on the hub surface between adjacent blades, is evenly equipped with and leadsStream bar is evenly equipped with the fine particle that raises up on the sidewall of described blade, for strengthening and the frictional force of fluid.
In technique scheme, the height of described flow guide bar is greater than 1/3rd of blade height.
In technique scheme, the upper end of described flow guide bar is tooth-shape structure.
In technique scheme, the quantity of described blade is 6-9.
In technique scheme, on the hub surface between adjacent described blade, be evenly equipped with 2 flow guide bars.
Than prior art, half-opened impeller of the present utility model comprises: wheel hub and be distributed in described wheel along even circumferentialMultiple blades of hub one side surface, wherein, described blade is hollow cavity the surface that is welded on wheel hub, adjacent blades itBetween hub surface on be evenly equipped with flow guide bar, on the sidewall of described blade, be evenly equipped with the fine particle that raises up, for addingThe frictional force of large and fluid, the utility model combines the granule raising up and flow guide bar, increasing impeller and fluidFrictional force, meanwhile, blade is hollow cavity, reduces the weight of impeller, reduces the mechanical loss of centrifugal water pump.
Brief description of the drawings
Fig. 1 is the structural representation of half-opened impeller of the present utility model;
Fig. 2 is the structural representation of half-opened impeller Leaf of the present utility model.
Wherein, 1 is blade, and 2 is flow guide bar, and 3 is wheel hub.
Detailed description of the invention
Below in conjunction with accompanying drawing, half-opened impeller of the present utility model is elaborated.
As shown in accompanying drawing 1-2, a kind of half-opened impeller, comprising: wheel hub 3 and be distributed in described wheel hub one along even circumferentialSix blades 1 of side surface, wherein, described blade is hollow cavity the surface that is welded on wheel hub, between adjacent bladesOn hub surface, be evenly equipped with the flow guide bar 2 that 2 height are blade height 1/3rd, the upper end of flow guide bar is tooth-shape structure(not shown), for strengthening the frictional force of impeller and fluid. On the sidewall of described blade, be evenly equipped with and raise upFine particle (not shown), equally also for strengthening and the frictional force of fluid.
Half-opened impeller of the present utility model combines the granule raising up and flow guide bar, increasing impeller and fluidFrictional force, meanwhile, blade is hollow cavity, as shown in Figure 2, reduces the weight of impeller, minimizing centrifugal water pumpMechanical loss.
Above the utility model is done to exemplary description, should be noted that and do not departing from core of the present utility modelSituation under, any simple distortion, amendment or other those skilled in the art can not spend creative work etc.All fall into protection domain of the present utility model with replacement.
