Description
Technical field
The present invention relates to a kind of pumps, and in particular to a kind of vertical pump.
Background technology
Currently, with the rapid development of the national economy, China is faced with huge energy demand and severe Energy situation,
For pumping this universal machine, its performance is improved, is had great importance to saving energy consumption.
Make designed pump function admirable, the impeller of only function admirable is inadequate, it is necessary to have and be matched therewith
Parts integrally can be only achieved best effect.Studies have shown that impeller blade suction surface is minimum close to entry zone pressure, have
When will appear negative value, which is possible to that cavitation corrosion will occur.It, can be by controlling blade or impeller inlet under certain relative case
Velocity of medium controls its inlet pressure, and so as to improve cavitation erosion, cavitation phenomenon, and to have rotation simultaneously existing for the fluid for entering impeller
As not flowed by the situation of anticipation when this phenomenon causes fluid to enter blade, to bring energy consumption at once.Inlet whirl is adjusted
Technology is adjusted at the beginning of the fifties in last century applied to wind energy conversion system operating mode, achieves preferable regulating effect.After the eighties in last century
Phase, domestic scholars also set about studying from this direction, for a long time, have one for the racemization aspect of impeller of pump inlet fluid
Fixed breakthrough.Spatial guide blade has many advantages, such as that radial dimension is small, can coordinate with impellers streamline smoothnesses such as mixed-flow pump or Pump for well, just
As a kind of common water distributor.The mentality of designing is mainly to solve the above two large problems as starting point, for impeller of pump
The rotation of inlet fluid and the control of flow velocity have certain improvement, but ineffective.
Invention content
To solve the above-mentioned problems, the present invention provides a kind of vertical pump, and performance is high, and energy consumption is small.
To achieve the goals above, the present invention uses following technical scheme：A kind of vertical pump, including pump shaft, under pump shaft
End outer wall is disposed with lower bearing, and pump shaft periphery wall is equipped with axle sleeve, is connected with impeller on pump shaft axle body, the pump shaft lower end is fixed with
Pump shaft suction casing, the suction casing include the kuppe for being connected to pump shaft lower end, and the kuppe peripheral surface is streamlined, leads
Flowing has the big blade of circumferentially uniform intervals arrangement on the peripheral surface of cover, vanelets are disposed between two adjacent big blades.
What the present invention was brought has the beneficial effect that：By the two distinct types of blade of size by the wheel hub and shell of suction casing
It connects, simultaneously support wheel hub and shell and forms an equal amount of space with hub shell, which is pumped (conveying) medium
By space, two kinds of spacing with blades are uniformly distributed in wheel hub, on shell, and symmetrical arrangement can more make the axisymmetric entrance of medium
Impeller, performance is high, and energy consumption is small.
Description of the drawings
Fig. 1 is the sectional view of the present invention；
Fig. 2 is the big and small blade schematic diagram of the present invention；
Fig. 3 is suction casing schematic diagram of the present invention.
Specific implementation mode
As shown in Figs. 1-2, the lower end outer wall of a kind of vertical pump, including pump shaft 10, pump shaft 10 is disposed with lower bearing 2, pump shaft
10 periphery walls are equipped with axle sleeve, are connected with impeller 1 on 10 axle body of pump shaft, 10 lower end of pump shaft is fixed with pump shaft suction casing, described
Suction casing include the kuppe 20 for being connected to 10 lower end of pump shaft, 20 peripheral surface of the kuppe is streamlined, kuppe 20
There is the big blade 21 of circumferentially uniform intervals arrangement on peripheral surface, vanelets 22 are disposed between two adjacent big blades 21.Institute
The big blade 21 stated is 4, and the vanelets 22 are 4.
Further, the kuppe 20 is bowl-shape in what Open Side Down, and kuppe 20 is fixed by bolt and pump shaft to be connected
It connects.
The wheel hub of suction casing is connected with shell by size two distinct types of blade, simultaneously supports the two simultaneously
Formed eight an equal amount of spaces, the space are pumped (conveying) medium by space, and two kinds of spacing with blades are uniformly distributed
In on wheel hub, shell, symmetrical arrangement can more make medium is axisymmetric to enter impeller.
The circumferential uniformly alternate arrangement of big and small blade, the medium for entering the part is separated, runoff is situated between during the space
Reduction of the non axial rotary speed in gradually smaller fluid space as early as possible existing for matter itself, as shown in figure 3, being cut from M-M
When surface current to the sections N-N, it is ensured that the medium flowed out from each small space has equal or similar flow velocity, reduces conveying and is situated between
Due to the shock energy consumption that flow velocity is not brought etc. when matter is met, and the part is simple prismatic blade, and outlet blade angle is 90 °,
The entrance impeller of the certifiable medium for leaving blade without spin, the effect of as its racemization embody, and equally, racemization removes and plays guarantee
Except in the case of pumped (conveying) medium flowing more adapts to impeller blade, also acting as reduces when pumped (conveying) medium meets since flow velocity is not brought not etc.
Shock energy consumption effect.
Further, the big blade 21, vanelets 22 are prismatic blade, and leaf top is arc-shaped, and nock is inwardly.
The application could be used without the prismatic blade of any distortion, can reach the condition of expectation state in the media flow of guarantee into impeller
Under, the manufacture of blade and difficulty of processing in production process greatly reduces, while improving economy.
Further, the access 201 of conveying oil is offered on the kuppe 20, oil is delivered to bearing 2 from access 201
With the junction of pump shaft 10.So that the medium of impeller inlet is entered bearing portion, plays lubrication, cooling.
As shown in figure 3, further, the thickness of the blade root section of the big blade 21 is more than the thickness of leaf top section, described
Vanelets 22 blade root section thickness be more than leaf top section thickness.It is gradually thinning from the sections M-M to N-N section blades, in this way
A small spreading morphology is formd in overall structure, is more advantageous to conversion of the pumped (conveying) medium energy from kinetic energy to pressure energy,
Impeller or vane inlet speed can be controlled as certain value, for reality, control and ensure that a certain extent the cavitation erosion of pump.
The thinning trend of blade more makes the medium flowed out from each space have smaller shock when being detached from blade, reduces energy and disappears
The possibility of consumption.
The basic principles and main features and the features of the present invention of the present invention have been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
Change and improvement is both fallen in the range of claimed invention.The scope of protection of present invention is by appended claims
And its equivalent thereof.
