Abstract
The invention relates to a novel impeller, which comprises an impeller hub, a middle steel plate and an impeller port ring. The impeller is characterized in that: a plurality of stainless steel pipes are distributed on the middle steel plate of the impeller along the circumference of the middle steel plate; and all the stainless steel pipes are welded on the middle steel plate, the stainless steel pipes are bent in arc, and the directions of all the stainless steel pipes are the same. The impeller has the advantages of low hydraulic loss and high efficiency of a pump, and can ensure different performance requirements of users and meet the requirements of low specific speed pumps on low flow and high lift.
Description
Technical field
The present invention relates to a kind of impeller, particularly a kind of novel impeller.
Background technique
Existing impeller is mainly formed (seeing accompanying drawing one) by several parts such as front shroud of impeller 11, impeller blade 12, back shroud of impeller 13, impeller hubs 14.Because the characteristics of low specific speed pump impeller are: the external diameter of impeller is relatively large and exit width impeller is little, is the cast inblock structure and existing impeller adopts, so limited the low specific speed pump performance.There is following shortcoming in it: exit width impeller is little because the external diameter of low specific speed pump impeller is relatively large, when adopting the cast inblock structure, is easy to produce casting defect, makes blade surface uneven, has influenced pump performance; When the exit width of impeller was too small, integral wheel also can not cast.
Summary of the invention
The objective of the invention is to solve existing the problems referred to above of water pump vane in the prior art, a kind of novel impeller is provided.The present invention designs a kind of novel impeller, comprises impeller hub, middle steel plate, impeller port ring, it is characterized in that: the middle steel plate circle distribution has some Stainless Steel Tubes in the middle steel plate upper edge of impeller.It is characterized in that: all Stainless Steel Tubes are welded on the middle steel plate, and Stainless Steel Tube is convexly curved, and the direction of all Stainless Steel Tubes is identical.Advantage of the present invention is that hydraulic loss is little, and the efficient height of pump can guarantee user's different performance requirement, the requirement that the flow that has satisfied loaw specific speed pump is little, lift is high.
Description of drawings
Accompanying drawing 1 is the prior art constructions schematic representation, and Fig. 2 is the side schematic view of Fig. 1,
Accompanying drawing 3 is a structural representation of the present invention, and Fig. 4 is the side schematic view of Fig. 3,
Below in conjunction with drawings and Examples the present invention is elaborated,
Embodiment
Comprise impeller hub 3, middle steel plate 4, impeller port ring 1 among the figure, it is characterized in that: the middle steel plate circle distribution has some Stainless Steel Tubes 2 in the middle steel plate upper edge of impeller.It is characterized in that: all Stainless Steel Tubes are welded on the middle steel plate, and Stainless Steel Tube is convexly curved, and the direction of all Stainless Steel Tubes is identical.
The runner of impeller is designed to the Stainless Steel Tube structure, and Stainless Steel Tube is evenly distributed on the circumferential position of 360 ° of middle steel plates, the centre is welded with steel plate 4.Because the runner of impeller has adopted the Stainless Steel Tube structure, different performance requirement according to the user, Stainless Steel Tube 2 is chosen as different calibers, because the inner wall smooth of Stainless Steel Tube 2, so hydraulic loss is little, the efficient height of pump can guarantee user's different performance requirement, the requirement that the flow that has satisfied loaw specific speed pump is little, lift is high.
Claims (2)
1. a novel impeller comprises impeller hub, middle steel plate, impeller port ring, it is characterized in that: the middle steel plate circle distribution has some Stainless Steel Tubes in the middle steel plate upper edge of impeller.
2. by the described a kind of novel impeller of claim 1, it is characterized in that: all Stainless Steel Tubes are welded on the middle steel plate, and Stainless Steel Tube is convexly curved, and the direction of all Stainless Steel Tubes is identical.
