Description
Technical field
This utility model relates to a kind of centripetal pump, particularly relates to a kind of centripetal pump with bicircular arcs runner.
Background technology
Centripetal pump is the distinctive a kind of output device of centrifugal separator, and centripetal pump is typically made up of with pump cover the pump housing, uses
Rivet interlacement is an entirety, as shown in Figure 1.Centripetal pump is the equal of " liquid stream guide ", guides liquid by centripetal pump runner
Body flowing realizes two kinds of transformations: one is the transformation flowed to, and by centripetal pump runner, the fluid flow direction of revolution is from tangential conversion
To being close to radially, liquid enters impeller central pipeline from pump chamber through vane edge；Another is the transformation of form of energy, makes liquid
The kinetic energy having is converted to pressure energy, in order to overcome the resistance of output liquid, drives liquid output.Centripetal pump passage curve such as figure
Shown in 2, this runner uses multi-section circular arc to be formed by connecting, and is " diffusion " rather than " convergence ", and the area of runner section is with stream
Road progressively strengthens, in order to the flow velocity of liquid stream progressively slows down, and reaches the purpose of energy conversion；The inlet angle of runner is the least, almost cuts
Line direction so that it is consistent with the direction of liquid stream, with reduce to greatest extent when liquid stream enters centripetal pump impeller with the rushing of runner
Hit, it is to avoid liquid stream generation disturbance and form turbulent flow, cause energy loss.But this centripetal pump there is also certain problem, first
First often occurring riveting when riveting loosely causes the pump housing and pump cover laminating bad, so that there is gap in the pump housing and pump cover, by
This conveying capacity reduces, and conveying liquid produces the phenomenon such as foam, emulsifying；Secondly as liquid is turned by warp-wise in course of conveying
Changing to axial direction, energy loss is relatively big, and efficiency is substantially reduced.
Utility model content
Technical problem to be solved in the utility model is, the shortcoming overcoming prior art, it is provided that a kind of bicircular arcs runner
Centripetal pump, uses oblique centripetal pump, and is respectively adopted one group of rivet joint at inside and outside two circles, have reduction conveyance loss, it is to avoid
Gap occurs, is effectively improved the feature of transfer efficiency.
In order to solve above technical problem, this utility model provides a kind of bicircular arcs runner centripetal pump, including the pump housing, pump cover
And rivet, the pump housing has through passage from top to bottom, the lower end of passage has peripherally outwardly extending oblique section, passage
The radial direction of oblique section of excessive position be fillet structure with axial junction, oblique section is passed through two groups of rivet joint pump covers, two groups
Rivet is that Internal and external cycle mode is distributed.
Using oblique centripetal pump main body, the radial direction oblique section of excessive position is transformed into axial junction increase fillet and subtracts
Little conveyance loss；Use two groups of rivets be distributed in the inside and outside two fixing pump covers of circle with oblique section, solve laminating loosely, between easily producing
The problem of gap.
The technical scheme that this utility model limits further is: vias inner walls uses bicircular arcs Curved runner, and bicircular arcs is bent
Line runner is divided into outer side runner and interior side runner, and between outer side runner and interior side runner, changes of section smooths.From the inlet to the outlet
The change of cross section of fluid channel progressively expands, and change is smooth, and sudden change, will not cause turbulent flow, effectively solves low the asking of transfer efficiency
Topic.
The beneficial effects of the utility model are: primary structure uses oblique centripetal pump main body, when being radially transformed into axial
Increase fillet and reduce conveyance loss, use two groups of rivets to be distributed in inside and outside two circles, can effectively solve to fit loosely, easily produce
The problem in raw gap, the change of bicircular arcs curved channel cross section of fluid channel from the inlet to the outlet progressively expands, and change is smooth, the most prominent
Become, turbulent flow will not be caused, effectively solve the problem that transfer efficiency is low.

Detailed description of the invention
Embodiment 1
A kind of bicircular arcs runner centripetal pump that the present embodiment provides, as it is shown in figure 1, include the pump housing 1, pump cover 2 and rivet 3,
Having through passage in the pump housing 1 from top to bottom, the lower end of passage has peripherally outwardly extending oblique section, passage oblique
The radial direction of section excessively position is fillet structure with axial junction, and oblique section couples pump cover by two groups of rivets 3, two groups of rivets 3
It is distributed in Internal and external cycle mode.
Using oblique centripetal pump main body 1, the radial direction oblique section of excessive position is transformed into axial junction increases fillet
Reduce conveyance loss；Use two groups of rivets 3 be distributed in the inside and outside two fixing pump covers of circle 2 with oblique section, solve laminating loosely, easily produce
The problem in raw gap.
Vias inner walls uses bicircular arcs Curved runner, and bicircular arcs Curved runner is divided into outer side runner 5 and interior side runner 4, outward
Between side runner 5 and interior side runner 4, changes of section smooths.The change of cross section of fluid channel progressively expands from the inlet to the outlet, and change is flat
Sliding, sudden change, will not cause turbulent flow, effectively solves the problem that transfer efficiency is low.
This utility model uses oblique centripetal pump main body, increases fillet when being radially transformed into axial and reduces conveying damage
Lose, use two groups of rivets to be distributed in inside and outside two circles, can effectively solve to fit loosely, the problem easily producing gap, bicircular arcs
The change of curved channel cross section of fluid channel from the inlet to the outlet progressively expands, and change is smooth, and sudden change, will not cause turbulent flow, have
Effect solves the problem that transfer efficiency is low.
In addition to the implementation, this utility model can also have other embodiments.All employing equivalents or equivalence become
Change the technical scheme of formation, all fall within the protection domain of this utility model requirement.
