Summary of the invention
The technical problems to be solved in the utility model overcomes above-mentioned the deficiencies in the prior art exactly, and provides a kind of pump Full-open impeller that can improve pump service life.
For solving above-mentioned technical problem, the technical solution of the utility model is:
A kind of pump Full-open impeller of design, including impeller body, this impeller body includes wheel hub and blade, described blade has multiple, and be radially uniformly arranged along hub surface, wherein blade includes entrance limit, Exit-edge and outer rim, the entrance limit of described blade and Exit-edge relative to hub axis respectively in certain inclination angle, being respectively equipped with in subtriangular connection cover plate between outer rim place and the wheel hub of each vanes close end, described connection cover plate and wheel hub end face are set in parallel.
Preferably, in said pump with, in Full-open impeller, connecting side relative to cover plate, be provided with wear-resistant block at the outer rim entrance edge tail place of blade open end.
Preferably, in said pump with in Full-open impeller, relative to the entrance limit of blade, wheel hub end face is radially laid with multiple balance pipe, and balance pipe is through-hole structure.
Preferably, in said pump with in Full-open impeller, the quantity of described blade is 3-6.
Technical solutions of the utility model provide the benefit that:
This utility model pump Full-open impeller by adding a subtriangular cover plate between impeller blade outer rim and wheel hub, for support blade, it is possible to prevent blade wear from bending occurring, curling, contribute to balancing axial thrust, and have good wearability, it is easy to maintenance.
Additionally, it is not be provided with wear-resistant block in blade outer rim, easy to wear, improve the service life of blade and pump；Coordinating blade to be provided with one group of balance pipe, and balance pipe is through-hole structure, and its quantity is consistent with blade quantity, contributes to reduction pressure pulse so that the quality of paper can uniformity, the yield of raising paper and quality.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail, wherein:
Fig. 1 is the sectional structure schematic diagram of this utility model pump Full-open impeller；
Fig. 2 is the right TV structure schematic diagram shown in Fig. 1；
Sequence number in figure: 1, wheel hub,
2, blade, 2-1, entrance limit, 2-2, Exit-edge, 2-3, outer rim,
3, cover plate is connected, 4, wear-resistant block, 5, balance pipe.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model; technical scheme in this utility model embodiment is carried out clear complete description; obviously described embodiment is only the schematic part detailed description of the invention of this utility model; it is not limited to scope of the present utility model; any those skilled in the art, without departing from this utility model design and made equivalent variations and amendment under the premise of principle, all should belong to the scope of this utility model protection.
Referring to Fig. 1-2, in figure, this utility model pump Full-open impeller, including impeller body, this impeller body includes wheel hub 1 and blade 2, described blade has multiple, and be radially uniformly arranged along hub surface, wherein blade includes entrance limit 2-1, Exit-edge 2-2 and outer rim 2-3, the entrance limit of described blade and Exit-edge are certain inclination angle respectively relative to hub axis, being respectively equipped with in subtriangular connection cover plate 3 between outer rim place and the wheel hub of each vanes close end, described connection cover plate and wheel hub end face are set in parallel.
During use, due between impeller blade outer rim and wheel hub plus a subtriangular cover plate, for support blade, it is possible to prevent blade wear from bending occurring, curling, contribute to balancing axial thrust, and have good wearability, it is easy to maintenance.
In this utility model one specific embodiment, referring in Fig. 1, figure, in said pump with, in Full-open impeller, connecting side relative to cover plate, be provided with wear-resistant block 4 at the outer rim entrance edge tail place of blade open end.This structural design is favorably improved the anti-wear performance of blade, thus improving the service life of blade and pump.
In this utility model one specific embodiment, referring in Fig. 2, figure, in said pump with in Full-open impeller, relative to the entrance limit of blade, wheel hub end face is radially laid with multiple balance pipe 5, and balance pipe is through-hole structure.Coordinating blade to be provided with one group of balance pipe, and balance pipe is through-hole structure, and its quantity is consistent with blade quantity, contributes to reduction pressure pulse so that the quality of paper can uniformity, the yield of raising paper and quality.
Concrete, referring in Fig. 2, figure, in said pump with in Full-open impeller, the quantity of described blade is three, and the quantity of its corresponding balance pipe also has three.
During use, owing to fan pump Impeller Design becomes single-stage single-suction horizontal structure, impeller can adopt closed, close after opening before may be used without, adopt interlaced blade, in the middle of two-layer blade, have dividing plate, two-layer blade mutually to stagger half blde pitch, and exit edge of blade and impeller central form an oblique angle, impeller blade is more, has 6-12 sheet according to impeller size every layer, and pressure pulse so can be made to be preferably minimized, so that the quality of paper can uniformity, the yield of paper and the quality of paper can be improved.
In this specification, each embodiment adopts the mode gone forward one by one to be described, and what each embodiment stressed is the difference with other embodiments, and between each embodiment, identical similar part is cross-referenced.
Described above to disclosed embodiment, makes those skilled in the art be capable of or uses this utility model.Revising apparent to those skilled in the art to the many places of these embodiments, generic principles defined herein under the premise without departing from the spirit or scope of utility model, can realize in other embodiments.Therefore, this utility model will be not restricted to these embodiments illustrated herein, and be to fit to the widest range consistent with principles disclosed herein and features of novelty.
