Abstract
The utility model relates to a combined type double-suction pump impeller in connection with a pump shaft; the impeller comprises a left half impeller and a right half impeller which are respectively manufactured and are in connection with the pump shaft to form a double-suction pump impeller. Compared with prior arts, the combined type double-suction pump impeller possesses the advantages of simple manufacture, low disability rate, convenient use, etc.
Description
Technical field
The utility model relates to a kind of impeller of double suction pump, especially relates to a kind of combined type double suction pump impeller.
Background technique
Now, the double-sucking type pump impeller of global general-use is cast inblock (or welding).And there is multiple shortcoming in the integrated type double-entry impeller:
1, there is cavity in its inside, and the sand of the inside is not easy to clean out, cause when assembling sand come off, make that impeller is uneven to be increased, abrade impeller endoporus and pump shaft surface simultaneously.
2, the integrated type double-entry impeller is when casting, and the defective of misrun appears in the blade suction side of this side that makes progress easily, has a strong impact on the outward appearance of pump performance and impeller.
3, the integrated type double-entry impeller is in when casting, and the dividing plate (back shroud that is equivalent to single suction impeller) in the middle of the blade of the left and right sides is often because thin excessively (the thick axial dimension that then increases impeller can reduce pump performance simultaneously.) and cause the casting difficulty.
4, more steady when making pump operation, the blade of the left and right sides of double-entry impeller requires interlaced arrangement.But this requirement can not guarantee by mould, thereby do not make the blade interlaced arrangement when causing casting easily.
5, the integrated type impeller is if a side is scrapped, and then whole impeller can only be scrapped.
6., the integrated type impeller can only remove uneven weight at front shroud or seal ring end, influences pump performance and outward appearance;
7, there is discontinuous surface in the endoporus of whole double-entry impeller, adds the size error and the form error that will make the hole man-hour and increases.Simultaneously cutting edge roundness is also formed impact, influence the life-span of cutter.
, integrated type impeller casting technique complexity, the single-piece volume and weight is big, makes troubles to production.
The model utility content
The purpose of this utility model is exactly to provide a kind of make simple, scrappage combined type double suction pump impeller low, easy to use for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions: a kind of combined type double suction pump impeller, be connected with pump shaft, it is characterized in that, this impeller comprises a left side half impeller and right half impeller of making respectively, a described left side half impeller and right half impeller are connected in pump shaft, form a double suction pump impeller.
Compared with prior art, the utlity model has following advantage:
1, there is cavity in integrated type double-entry impeller inside, and the sand of the inside is not easy to clean out, cause when assembling sand come off, make that impeller is uneven to be increased, abrade impeller endoporus and pump shaft surface simultaneously.Then there is not this problem in combination type blade wheel;
2, the integrated type double-entry impeller is when casting, and the defective of misrun appears in the blade suction side of this side that makes progress easily, has a strong impact on the outward appearance of pump performance and impeller.Then there is not this problem in the combined type double-entry impeller;
3, the integrated type double-entry impeller is in when casting, and the dividing plate (back shroud that is equivalent to single suction impeller) in the middle of the blade of the left and right sides is often because thin excessively (the thick axial dimension that then increases impeller can reduce pump performance simultaneously.) and cause the casting difficulty.And the back shroud of combination type blade wheel can be cast suitably thickly, and then turning is to the thickness that needs;
4, more steady when making pump operation, the blade of the left and right sides of double-entry impeller requires interlaced arrangement.But this requirement can not guarantee by mould, thereby do not make the blade interlaced arrangement when causing casting easily.And the blade interlaced arrangement that combination type blade wheel only need guarantee left and right sides two halves impeller at processing keyway this procedure just can, production management is more convenient;
5, one group of combined type double-entry impeller also can be used as the two stage pump of an axial force self-balancing even the impeller of multistage pump, thereby makes impeller be common to the pump of two series, and the generalization degree of product is improved;
6, the integrated type impeller is if a side is scrapped, and then whole impeller can only be scrapped.And in the combination type blade wheel half scrap, and can not have influence on second half;
7, on the back shroud of a left side half impeller and right half impeller, remove the unbalanced weight amount, can not have influence on the outward appearance and the performance of impeller.And the integrated type impeller can only be removed uneven weight at front shroud or seal ring end, influences pump performance and outward appearance;
8, with respect to the integrated type impeller, the mould and the casting technique of combination type blade wheel are simplified greatly, thereby significantly reduce the foundry goods scrappage;
9, there is discontinuous surface in the endoporus of whole double-entry impeller, adds the size error and the form error that will make the hole man-hour and increases.Simultaneously cutting edge roundness is also formed impact, influence the life-span of cutter.The endoporus of half impeller of combination type blade wheel is continuous surface, avoids producing the problems referred to above;
10, the volume and weight of combined semi impeller is approximately half of integral wheel, thereby is more convenient for adopting precision casting process to produce blank, thus complete machine performance and new approach of component appearance quality increase for improving double suction pump.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
As shown in Figure 1, a kind of combined type double suction pump impeller, this impeller comprise a left side half impeller 1 and right half impeller of making respectively 2, and left half impeller 1 is being assembled to formation double-entry impeller in back on the pump shaft with right half impeller 2.A left side half impeller 1 is connected with pump shaft by flat key with right half impeller 2.Because the impeller of integral body is split into two independent parts, assemble then, misrun can not appear therefore.When casting, the back shroud of combination type blade wheel can be cast suitably thickly, and then turning is to the thickness that needs.When the weight imbalance appears in the impeller that casts out, can on the back shroud of a left side half impeller and right half impeller, remove the unbalanced weight amount.Usually more steady when making pump operation, the blade of the left and right sides of double-entry impeller requires interlaced arrangement, and combination type blade wheel guarantees the blade interlaced arrangement of left and right sides two halves impeller by the processing keyway.If half in the combination type blade wheel breaks down, only half that need will break down more changed and got final product, and can not have influence on second half, thus escapable cost.
Claims (1)
1. a combined type double suction pump impeller is connected with pump shaft, it is characterized in that, this impeller comprises a left side half impeller and right half impeller of making respectively, and a described left side half impeller and right half impeller are connected in pump shaft, form a double suction pump impeller.
