Abstract
The utility model relates to an efficient centrifugal pump impeller structure used for increasing lift. The efficient centrifugal pump impeller structure comprises a wheel disc, a shaft hole is formed in the center of the wheel disc which is provided with an upper surface and a lower surface, a plurality of blades are arranged on the upper surface of the wheel disc, one end of each blade is connected to the wheel disc, the other end of each blade is connected to a wheel hub, a three-dimensional flow parabolic baffle is arranged between every two adjacent blades, a flow channel is formed between each three-dimensional flow parabolic baffle and the wheel disc, and through holes are also formed in the wheel disc. According to the efficient centrifugal pump impeller structure, by arranging the three-dimensional flow parabolic baffles, each flow channel consistent with the gap between the corresponding adjacent blades in shape is formed, and the lift of a 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, when 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 of judgement 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, when 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, upper surface at wheel disc is provided with a plurality of blades, and 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.
Further, on described wheel disc, be also provided with through hole.
Further, 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.
Further, 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.
Accompanying drawing explanation
Fig. 1 is that the utility model is a kind of for improving the structural representation of the efficient centrifugal pump blade wheel structure of lift.
In figure: 1, wheel disc; 2, axis hole; 3, blade; 4, three-dimensional flow parabola catch; 5, runner; 6, through hole.
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.
Refer to Fig. 1, Fig. 1 is that the utility model is a kind of for improving the structural representation of the efficient centrifugal pump blade wheel structure of lift.
Described 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, described wheel disc 1 has upper surface and lower surface, upper surface at wheel disc 1 is provided with five blades 3, and one end of described blade 3 is connected on wheel disc 1, and the other end is connected on wheel hub, 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.Flow Q(m when centrifugal pump
3/ h), lift H(m) and after motor speed n (r/ min) determines, the impeller outer diameter D(m of centrifugal pump) and impeller channel clear span B(m) by formula calculus of approximation below, draw 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.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
