Abstract
The utility model discloses a staggered, symmetrical and energy-saving type dual-suction pump impeller which comprises a left hub, blades and a right hub. The staggered, symmetrical and energy-saving type dual-suction pump impeller is characterized in that a middle hub (2) is added in the impeller, two groups of blades (3) in the same number are evenly distributed on the two sides of the middle hub (2), and the adjacent blades on the two sides are mutually staggered. The staggered, symmetrical and energy-saving type dual-suction pump impeller reduces unbalanced stress on the two sides of the blades when the impeller rotates, prolongs the service life of the blades, improves pump lift, enables water flow to be more stable, improves the efficiency of a pump and saves energy consumption.
Description
Technical field
The utility model relates to the pump class, relates in particular to the energy-saving double-suction pump impeller of a kind of staggered symmetry.
Background technique
The pump leaf can be applicable to the every field pumping unit, in industrial or agricultural, is commonly employed.As steel industry, for water irrigation system, petroleum industry, power generation system, chemical industry etc., all used in a large number pumping unit, the structure of pump leaf and manufacturing property directly affect whole system.
Existing pump machine adopts one group of blade, and during the running of pump machine, sharf, to the one-sided extruding force that is subject to water, is subject to force unbalance, and blade easily consumes, and also easily causes the wearing and tearing of impeller shaft, reduces the working life of pump machine.Simultaneously,, at the neutral gear of vane rotary, there is the stream impulse phenomenon in the pump machine, and the part current are back in the pump machine, makes the effective head of pump machine reduce, and the current fluctuation is unfavorable for producing and uses.
The model utility content
The purpose of this utility model be while reducing impeller operation the blade both sides be subject to force unbalance, improve blade working life, improve pump machine lift simultaneously, make current more steady, improve the efficiency of pump machine.
For realizing above purpose, the technological scheme that the utility model adopts is: the energy-saving double-suction pump impeller of a kind of staggered symmetry, and it comprises left wheel hub, blade and right wheel hub; It is characterized in that: described impeller has increased middle wheel hub (2), and middle wheel hub (2) both sides are evenly distributed with two groups of blades (3) that quantity is equal, and both sides adjacent blades (3) is interlaced.
Further, described middle wheel hub (2) and blade (3) integrally casting, and with wheel shaft, do not contact.
Further, the staggered impeller blade spacing that differs half of described middle wheel hub (2) both sides blades (3).
Further, described blade (3) is one-sided is at least 2.
Further, described blade (3) is one-sided is 6.
The beneficial effects of the utility model: 1, adopt two groups of blades, bilateral water suction, effectively reduced the unbalanced force of the current that impeller is subject to, and improves blade working life.
2, two groups of staggered symmetrical impeller blades, effectively reduce pulse and reflux, and improved the effective head of pump machine, and current are more steady, improve the efficiency of pump machine, energy efficient.
The accompanying drawing explanation
Fig. 1 is schematic perspective view of the present utility model.
Fig. 2 is left view of the present utility model.
Fig. 3 is main sectional view of the present utility model.
Numerical reference described in figure is expressed as: 1, left wheel hub; 2, middle wheel hub; 3, blade; 4, right wheel hub.
Embodiment
In order to make those skilled in the art understand better the technical solution of the utility model; below in conjunction with accompanying drawing, the utility model is described in detail; the description of this part is only exemplary and explanatory, should any restriction not arranged to protection domain of the present utility model.
As shown in Figure 1-Figure 3, structure characteristic of the present utility model is: it comprises left wheel hub 1, blade and right wheel hub 4; Impeller has increased middle wheel hub 2, and middle wheel hub 2 both sides are evenly distributed with two groups of blades 3 that quantity is equal, and single group blade is 6, and the both sides adjacent blades is interlaced.And middle wheel hub 2 and blade 3 integrally castings, and with wheel shaft, do not contact.The staggered impeller blade spacing that differs half of middle wheel hub 2 both sides blades.
When this example turns round in the pump machine, the two-way water suction in impeller both sides, effectively reduce the axial unbalanced force of current that impeller is subject to; Because the blade of middle wheel hub 2 both sides is interlaced, differ the impeller blade spacing half simultaneously, fall after rise when a lateral lobe sheet rotates to peak, while causing current to reflux, the blade of opposite side continues to promote lofty perch with the current post.So block the current of most of backflow, effectively improved the lift of pump machine, reduced the pulse backflow, made current more steady, improved the efficiency of pump machine.
It should be noted that, in this article, term " comprises ", " comprising " or its any other variant are intended to contain comprising of nonexcludability, thereby make the process, method, article or the equipment that comprise a series of key elements not only comprise which key element, but also comprise other key elements of clearly not listing, or also be included as the intrinsic key element of this process, method, article or equipment.
Applied specific case herein principle of the present utility model and mode of execution are set forth, the explanation of above example is just for helping to understand method of the present utility model and core concept thereof.The above is only preferred implementation of the present utility model, should be understood that, finiteness due to literal expression, and objectively there is unlimited concrete structure, for those skilled in the art, under the prerequisite that does not break away from the utility model principle, can also make some improvement, retouching or variation, also above-mentioned technical characteristics can be combined by rights; These improve retouching, change or combination, or without improving, the design of model utility and technological scheme are directly applied to other occasion, all should be considered as protection domain of the present utility model.
