This pump 1 also includes the first pipeline 21, and this first pipeline 21 launches from accommodating chamber 20.In the first mode of operation, described first pipeline 21 is conveyance conduit.Therefore, described first pipeline 21 is under stress from chamber 20 exhaust fluid.
This pump 1 includes the first ribs 31, and this first ribs 31 is through described first pipeline 21.The stream of fluid is divided at least two part by this first ribs 31.These two parts are assembled in the downstream of described first rib 31 again.
Therefore, this first rib is used for reinforcing this conveyance conduit, reduces the tension force of material to greatest extent, reduces deformation the most to greatest extent, and does not make the wall thickness dimension of the first pipeline 21 excessive.Accordingly, it is possible to reduce the external dimensions of pump 1 to greatest extent.
This first ribs 31 includes wing portion 310, and this wing portion 310 has aerodynamic type profile.This can make pressure drop minimize.In the case of reversible pump, it is likely to be of prior advantage, as the most more suitably explained.
This pump 1 advantageously comprises second pipe 22, and this second pipe 22 terminates at described receiving chamber 20.In the first mode of operation, this second pipe 22 is suction pipeline.
This pump 1 also includes the second ribs 32, and this second ribs 32 is through described second pipe 22.
Advantageously, this pump 1 is reversible.Therefore, this pump can also run in the second mode of operation, and in this second operator scheme, this first pipeline 21 becomes suction pipeline and this second pipe 22 becomes conveyance conduit.
In view of the reversibility of this pump 1, therefore, rib 32 is important in existing in second pipe 22.It practice, this second pipe 22 can also become conveyance conduit, accordingly, because the fluid being under pressure and stand substantial amounts of pressure.
Advantageously, this second ribs 32 includes wing portion 320, and this wing portion 320 has aerodynamic type profile.
In the first mode of operation, this feature is for making the pressure drop on absorption side minimize to reduce risk of cavitation (in the first mode of operation, this second rib 32 operates under air-breathing, and aerodynamic type profile contributes to this purpose).
Advantageously, this first pipeline 21 and second pipe 22 include two openings 23,24, and this opening 23,24 is positioned in the same wall of this pump 1, abreast towards outside.In the inside of this pump, this first and second pipeline 21,22 extend side by side.
In alternative embodiments, two openings 23,24 of this first pipeline 21 and second pipe 22 may be located on two different walls of this pump 1；Especially, two openings 23,24 can be horizontal.
Advantageously, this first pipeline 21 and the second rib 31 are single one-body molded main body.
In a preferred embodiment, in addition to this first pipeline 21 and first rib 31, being at least partially in single one-body molded main body of this second pipe the 22, second rib 32 and this receiving chamber 20.This single one-body molded main body is advantageously made of cast iron.This single one-body molded main body also limits external shell, and this external shell at least partly defines this pump 1 and outside.
As exemplified in figure 4, this first pipeline 21, second pipe 22, first rib 31 and the second rib 32 and at least some of of this receiving chamber are symmetrical relative to the mesion 4 being placed between described first pipeline 21 and second pipe 22.
This first rib 31 includes:
-first surface 311 and second surface 312, it is relative to each other；
The guide edge 313 of-this first rib 31 and outlet edge 314, this guide edge 313 and outlet edge 314 are round, and are interconnected to this first surface 311 and second surface 312.
Relative to from accommodating chamber 20 along this first pipeline 21 towards the outside path extended of pump 1, this first surface 311 and second surface 312 include part 315 and part 316, in this part 315, this first surface 311 and second surface 312 are separated from each other, in this part 316, first surface 311 and second surface 312 are mutually convergent.
One of two parts of stream divided by described first rib 31 skim over this first surface 311 and another part skims over this second surface 312.
This first pipeline 21 includes that first defines wall 25, and this first defines wall 25 and towards this first surface 311 and limit the concave surface towards this first surface 311.Similarly, this first pipeline 21 includes that second defines wall 26, and this second defines wall 26 and towards this second surface 312 and limit the concave surface towards this second surface 312.
This first rib 31 be connected to this one-body molded main body at its first end 317 with the second end 318 relative to remainder.This first end 317 to the second end 318 is closer to the outer surface of this pump.
The surface being in the lateral part that the surface ratio of at least one lateral part of centre records at described first end 317 and described second end 318 relative to described first end 317 and the second end 318 is little.Especially, string and/or the average thickness of this mid portion are less than the string of the lateral part recorded at this first end 317 and the second end 318 and/or average thickness.Lateral part mentioned above is along the direction orientation according to fluid and the Planar realization in the direction of this first end 317 crosscutting and the second end 318 joint.
In certain embodiments, this first rib 31 is bigger than in the lateral part of the second end 318 in the lateral part of the first end 317.
Advantageously, the content described above in conjunction with this first rib 31 and/or the first pipeline 21 can be recycled and reused for this second rib 32 and/or second pipe 22.
Therefore, the present invention conceived is obtained in that multiple advantage.
First, the present invention can reduce the overall dimension of pump 1.It practice, this first rib 31(is positioned in the first pipeline 21) conveyor side of this pump 1 can be reinforced, and do not increase the thickness of this pipeline.Additionally, at pump can reversing mode run and in the case of this first pipeline 21 serves as suction pipeline, the aerodynamic type shape in this wing portion makes it possible to avoid the notable pressure drop (and thing followed risk of cavitation) drawing on side
Therefore, without departing from the inventive concept of the premise, it is also possible to make some deformation and improvement, these broadly fall into protection scope of the present invention.Additionally, all details of the present invention all may be by the element substitution of technical equivalences.In practice, all material and the size of use can be as needed for any type.
