Abstract
The utility model relates to an efficient centrifugal pump impeller structure for increasing the head, comprising a roulette. The center of the roulette is provided with a shaft hole; the roulette is provided with an upper surface and a lower surface; multiple blades are arranged on the upper surface of the roulette; one end of each blade is connected onto the roulette, and the other of each blade is connected onto a hub; a three-dimensional flow parabolic catch is arranged between every two adjacent blades; flow channels are formed between the three-dimensional flow parabolic catches and the roulette; through holes are also formed in the roulette. According to the efficient centrifugal pump impeller structure, by arranging the three-dimensional flow parabolic catches, the flow channels with consistent gap and shape between the adjacent blades are formed, and the head of the centrifugal pump is increased.
Description
Technical field
The utility model relates to mechanical parts field, relates in particular to a kind of for improving the efficient centrifugal pump blade wheel structure of lift.
Background technique
Centrifugal water pump, in the time of work, due to impeller and fluid generation friction generation rotation, is converted into kinetic energy by mechanical energy, and then makes water pump produce flow and lift.The size of flow and lift is an important indicator that judges water pump quality.Because enterprise needs high efficiency work, so more and more need to use the centrifugal pump of the large lift of large flow.
In prior art, the measure that increases centrifugal pump lift size is the diameter that increases impeller, or increases the number of impeller, namely so-called multistage pump.But the problem that can produce so is again that, in the time increasing the diameter of impeller, the generation of the obviously mechanical loss of energy of increase, and then reduction kinetic energy, makes Centrifugal water pump Efficiency Decreasing.When increasing the number of impeller, can directly affect the complexity of centrifugal water pump structure, because every primary pump all can produce certain energy loss, so total efficiency can significantly reduce.
Model utility content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, provides a kind of for improving the efficient centrifugal pump blade wheel structure of lift.
The utility model is to be achieved through the following technical solutions:
A kind of for improving the efficient centrifugal pump blade wheel structure of lift, comprise wheel disc, described wheel disc central authorities are provided with axis hole, described wheel disc has upper surface and lower surface, at the upper surface of wheel disc, multiple blades are installed, one end of described blade is connected on wheel disc, and the other end is connected on wheel hub, three-dimensional flow parabola catch is installed between described adjacent blades, between described three-dimensional flow parabola catch and wheel disc, forms runner.
As preferably, on described wheel disc, be also provided with through hole.
As preferably, described through hole is regular hexagon, and described through hole is circumferentially distributed on wheel disc, and the quantity of described through hole is six.
As preferably, the quantity of described blade is five.
Compared with prior art, the beneficial effects of the utility model are: the utility model, by three-dimensional flow parabola catch is set, has formed the runner consistent with adjacent blades interval shape, has improved centrifugal lift of pump.
Brief description of the drawings
Fig. 1 is that the utility model is a kind of for improving the structural representation of efficient centrifugal pump blade wheel structure of lift.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, described is a kind of for improving the efficient centrifugal pump blade wheel structure of lift, comprise wheel disc 1, described wheel disc central authorities are provided with axis hole 2, and described wheel disc 1 has upper surface and lower surface, at the upper surface of wheel disc 1, five blades 3 is installed, one end of described blade 3 is connected on wheel disc 1, the other end is connected on wheel hub, and three-dimensional flow parabola catch 4 is installed between described adjacent blades 3, between described three-dimensional flow parabola catch 4 and wheel disc 1, forms runner 5.
On described wheel disc 1, be also provided with through hole 6, described through hole 6 is regular hexagon, and described through hole 6 is circumferentially distributed on wheel disc 1, and the quantity of described through hole 6 is six.The drinking water performance of impeller and send water-based all to have much room for improvement.
According to the needs to Centrifugal Pump Q and lift H in producing, external diameter and the width of design impeller.As the flow Q(m of centrifugal pump
3/ h), lift H(m) and motor speed n (r/min) determine after, the impeller outer diameter D(m of centrifugal pump) and impeller channel clear span B(m) draw by formula calculus of approximation below respectively:
D=85×H
0.5/n
B=Q×n/300000×H
Draw after key dimension D, the B of impeller, just can select according to the character of feed liquid material, inlet size and the diameter of axle etc. of impeller.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
