Abstract
The invention relates to a centrifugal pump impeller. The centrifugal pump impeller comprises a wheel disk; a shaft hole is formed in the center of the wheel disk; the wheel disk is provided with an upper surface and a lower surface; a plurality of blades are installed on the upper surface of the wheel disk; one end of each blade is connected to the wheel disk; the other end of each blade is connected to a hub; a three-dimensional flow parabolic blocking piece is installed between every two adjacent blades; a flow channel is formed between the three-dimensional flow parabolic blocking pieces and the wheel disk; through holes are further formed in the wheel disk. According to the centrifugal pump impeller, by arranging the three-dimensional flow parabolic blocking pieces, the flow channel with the shape consistent with that of an interval between every two adjacent blades is formed, and the lift of a centrifugal pump is increased.
Description
Technical field
The present invention relates to mechanical parts field, particularly relate to a kind of centrifugal pump impeller.
Background technique
Operationally, rotate because impeller and fluid occur to rub to produce, be kinetic energy by changes mechanical energy to Centrifugal water pump, and then make water pump produce flow and lift.The size of flow and lift is the important indicator judging water pump quality.Because enterprise needs high efficiency work, so more and more need the centrifugal pump using the large lift of large discharge.
In prior art, the measure increasing centrifugal pump lift size is the diameter increasing impeller, or increases the number of impeller, namely so-called multistage pump.But the problem that can produce so is again, when increasing the diameter of impeller, obviously can increase mechanical loss of energy, and then reducing the generation of kinetic energy, centrifugal water pump efficiency is reduced.When increasing the number of impeller, directly can affect the complexity of centrifugal water pump structure, because every primary pump all can produce certain energy loss, so total efficiency can significantly reduce.
Summary of the invention
The object of the invention is, in order to overcome the deficiencies in the prior art, to provide a kind of centrifugal pump impeller.
The present invention is achieved through the following technical solutions:
A kind of centrifugal pump impeller, comprise wheel disc, described wheel disc central authorities are provided with axis hole, described wheel disc has upper surface and lower surface, be provided with multiple blade at the upper surface of wheel disc, 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 the preferred technical solution of the present invention, described wheel disc is also provided with through hole.
As the preferred technical solution of the present invention, described through hole is regular hexagon, and described through hole circumference is distributed on wheel disc, and the quantity of described through hole is six.
As the preferred technical solution of the present invention, the quantity of described blade is five.
Compared with prior art, the invention has the beneficial effects as follows: the present invention, by arranging three-dimensional flow parabola catch, defines and runner that adjacent blades interval shape is consistent, improves centrifugal lift of pump.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of centrifugal pump impeller of the present invention.
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 object of the present invention, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Refer to Fig. 1, Fig. 1 is the structural representation of a kind of centrifugal pump impeller of the present invention.
Described a kind of centrifugal pump impeller, 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, be provided with five blades 3 at the upper surface of wheel disc 1, 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.
Described wheel disc 1 is also provided with through hole 6, and described through hole 6 is regular hexagon, and described through hole 6 circumference is 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 increase.
According to the needs to Centrifugal Pump Q and lift H in production, the external diameter of design impeller and width.As the flow Q (m of centrifugal pump
3/ h), after lift H (m) and motor speed n (r/min) determine, 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
After drawing the key dimension D of impeller, B, just can according to the material of the character selection impeller of feed liquid, inlet size and the diameter of axle etc.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
