Description

High-pressure vortex air pump

Technical field

The present invention relates to a kind of air blower, especially a kind of volution blast engine or vortex pump.

Background technique

Because the air blower that common name is air blower is a kind of kind for seriously lacking air pressure, do not go to discuss herein, if but For having demand to pressure-vaccum atmospheric pressure and cheap air blower, usual people buy vortex pump, because it passes in and out the same power of air pressure It is greater than seven times of ordinary blower or so times down.But the air pump of this imitated German universalness decades is pressed for design, is existed Major defect, the power of its only half is for generating positive/negative pressure (outlet just, air-breathing negative), its efficiency only fifty percent or so, very To less than romantic in vain half electric energy and price.

Summary of the invention

A kind of high-pressure vortex air pump is provided the purpose of the present invention is the major defect for the prior art, to make cost In similar situation, and positive and negative air-pressure doubles, and service efficiency doubles, and long-term power consumption is even more to save half.

The present invention is to solve disadvantages described above to take following technical scheme:

The present invention provides a kind of high-pressure vortex air pumps, including motor, pump case, impeller, lid, air inlet pipe, escape pipe, bottom Disk, blade, smooth arc connect spacing block.

Embodiment 1: the motor is attached to pump case axis, and installation is fixed with one heart, and Motor Shaft is concentric solid with key with impeller Fixed, the axle center of lid is fixed with the fixed not play of bearing socket motor output shaft end with pump case center.There is air inlet pipe below pump case The logical intracavitary blade side being directed toward on impeller of shell.

There is escape pipe to communicate therewith below the lid, and there is smooth arc to connect spacing block isolation air inlet pipe and escape pipe, makes mutually It not communicating closely, this is not connected and covers concentric boss and enters impeller recess and be isolated again, the isolation, they All it is slit isolation, i.e., rotating member and static element is not interfered to work.Rotating member only impeller and motor shaft are remaining static.

The air inlet pipe and escape pipe grow part can also be made it is seperated with main body, such as with the fixation of flange face contact.

There are several blades for being uniformly distributed homogenous quantities in the impeller periphery, it is characterized in that: blade is not traditional straight, and It is the oblique blade with arc hook；In addition blade bottom surface is not on straight bus, and non-median rise is made reinforced blade and subtracted Few wind area (because wind area is mating with power, can not greatly with it is small, big then the motor feels hot, and small then air quantity subtracts with pressure It is small).

In the middle part of the lid first protrusion boss can form outlet booster cavity, separately can then coincide with recess slit in the middle part of impeller Form isolation.Outlet booster cavity is it is characterized in that: forming duct bottom by lid inner periphery is gradually the equal proportion by air inlet big chamber Bottom to gas outlet outlet is gradually raised, is moved ahead if there is gas to be forced in duct at this time, air pressure can be higher and higher, and flow velocity can be more next It is more anxious, until gas outlet can generate more original high pressure；This first, this second, because original straight blade it be merely responsible for band and take offence Body advance to the direction of motion and squeeze gas to piece both sides squeeze out, for motor side originally do not need squeeze out gas, but with Part energy is offset in air inlet, though the gas squeezed out for outlet a part is useful, its direction is perpendicular to impeller end face, It is only turned to by impeller and generates clockwise direction movement, also counteract part energy, if there is the air-flow of clockwise direction is then original along walking The energy of counteracting is overcome or major part overcomes (related to arc cheicers degree), and the arc hook on blade is exactly this effect, then band Where is arc hook-type blade-section meaning? it is oblique perpendicular to the projection on electrical axis impeller curved surface, positive sense rotation because under Direction；It is constantly taken advantage of a situation incision by the inclined-plane from air intake duct air inlet, it is compared with flat blade: the former anti-gesture for promoting gas that it is allowed to come in In the presence of being overcome, just a positive and a negative, and sizable capacity usage ratio is strengthened, therefore it cuts gas such as knife, resistance because of inclined-plane It greatly reduces, therefore blade load also reduces simultaneously, and blade can be made to increase wind area, inclined-plane had not only been reduced by wind-force, but also stress point Cloth area increases, thus can do it is thin with it is light, and reduce using power.Or the blade can also be made into plane inclined tab.

Embodiment 2: become another smooth concave arc spacing block variation except escape pipe position and corresponding smooth arc connect spacing block Outside, remaining principle and explanation are constant, its spacing block becomes smaller, and the neutral gear phase becomes smaller, and blade action time is more, therefore air pressure and output Power is stronger.Air inlet pipe ditto directly leads to blade and air inlet reserve chamber.

In conclusion being known by calculating or being tested and show that same power pump, wind pressure and air quantity increase one times or more, it can be appreciated that Be blade angle shape and the data in outlet booster cavity section of successively decreasing can obtain extreme value, that is, optimize.So two times or more imitate (non-planar blade) then may be implemented in fruit.

Specific embodiment

Technical solution of the present invention is described in further detail with reference to the accompanying drawing.

Refering to attached drawing 1, Fig. 2, embodiment 1: the embodiment of the invention provides a kind of high-pressure vortex air pump, it include motor 1, Pump case 2, impeller 3, lid 4, air inlet pipe 5, escape pipe 6, chassis 7.

The motor 1 and pump case 2 are concentric affixed, 1 shaft of motor with impeller 3 is concentric is fixed with key, with bearing at 4 axle center of lid It is inserted in and connects the fixed lid 4 in shaft end out of motor 1, have air inlet pipe 5 below pump case 2, lead to intracavitary one of the blade 8 being directed toward on impeller 3 of shell Side.

There is escape pipe 6 to communicate therewith below the lid 4, and there is smooth arc to connect spacing block 9, it dynamically (can refer to leaf with slit When 3 rotation of wheel) air inlet and the anti-two shortness of breath roads of outlet is isolated,

The air inlet pipe 5 and escape pipe 6, can also be made it is spliced, it is easy to process with benefit；In addition air inlet pipe 5 and escape pipe 6 Angle α is formed with 8 axle center of impeller, the angle is small then high-efficient, because when smooth arc of the blade 8 Jing Guo relatively long distance connects spacing block 9 Neutral gear phase gas does not exchange generation, affects efficiency, only pulls open 9 distances due to consideration, which is put, just installs pipe fitting, or by this angle Become smaller as far as possible and height is put on chassis, when implementation is contemplated that this factor.

There are several uniformly distributed homogeneous blades 8 in the impeller periphery, it is characterized in that: blade 8 is and steering (see ω is turned in figure) To oblique and left side at big arc, arc end is in tilt down again on consistent right side.

First the 4 middle part boss of lid can hold one's breath with dynamic at 3 concave of impeller circle, and can form the non-of outlet booster cavity 10 The duct (non-close circle refer to is obstructed by lower isolation block) of closed circular, feature and pressurization principle are as follows: duct bottom be left side bottom by The duct initial point led at air inlet 5 is that the biggish point bottom a in section is begun, along duct back-roll rising row to b point, then is just turning around down To c point, the side edge bottom (i.e. connection a, b, c) of this duct is linear gradually high, therefore a, b, c are pressed in entire 10 section of outlet booster cavity Sequence is small by linear gradient, is minimum to the place c, finally smooth connection gas outlet is from 6 outlet of escape pipe.

The chassis 7 is fixed with 2 lower part of pump case, and has four holes to fix with basis.

Its course of work is as follows: by revolving speed vector ω rotation in figure after motor 1, which is powered, to be rotated, when impeller 3 is downward in Fig. 2 When rotation, blade 8 is because right side is to tilt down, and under normal air air pressure, this of 8 meanings tiltedly can will be clipped in each adjacent two Air driven actively easily slides according to inclined plane principle along inclined-plane to the left between piece blade, and air on right side just generates low gas after moving to left Pressure, including air inlet reserve chamber 11, due to there is an air inlet pipe 5, it, which leads to blade and ingresses, reaches at a after inlet air；Have one again A air inlet reserve chamber 11, its equal ingress of air of each blade 8, therefore for every blade 8 cut wind generate negative pressure, the suction function in Air inlet pipe 5, just generates the continuous air inlet of suction, and 8 inclined-plane of blade is like knife cuts the frankness of bean curd with flat-pushing wind compared with, therefore generation is very Small windage increases power, and is stooped arc on the left of blade 8, make the distinguished and admirable speed ratio revolving speed also get outta there left side, see arrow d, d Vertical component and vector ω it is in the same direction, it accelerates wind flow velocity in duct again, since duct is above-described from greatly to small section Face reason, with flow formula Q=sv, when flow is constant, (flow is pushed by force to a left side by inclined-plane at this time and does not back towards right side and keep It is approximate constant) section s is smaller, flow velocity v is faster, then by smooth bend c hereinafter, osculum extrusion just occur it is above it is double because The hyperbar (just) that element is constituted, (three arrows in duct referring to fig. 2: e is shorter arrow, and f is middle long arrow, and g is longest arrow Head expresses flow velocity from as low as big progressive formation)；Again because of cutting type beveled blade, it again compared with flat blade Bidirectional-squeezing much more efficient, Then air inversely being squeezed compared with flat blade in air inlet, two sides generate bilateral extrapolability to the left and right, are exactly to block for right side Gesture generates, and counteracts air inlet energy, and now on the contrary, be to become counter-force into propulsive force, and increases energy, this two thus just inhale More than power is doubled or is reached again.

The blade 8 has angle theta to be formed with 8 root of blade excessively as seen from Figure 1, it can be generated in band gas high-speed rotation Centrifugal force, the angle are to offset centrifugation, and the gas to prevent largely throwing away to top is shot back to form local line repeatedly again Stream or useless vortex, influence efficiency, and 2 inner circle of top, that is, pump case and common machine are different, do not stay obvious sky, and only micro seam is not with Blade 8 and the friction at top is caused to be advisable, because to account for percent small several for its influence.If details all pays attention to simultaneously the present invention everywhere Overcome, will appear a perfect product: its channel rule is very apparent, and air inlet 5 is advocated dynamic left into the blade Final 8 It pushes away and locates up to a, it is frank by the sharp left side for being cut into inclined-plane thrust in blade right side, it is each between air two blades 8 because pushing away at a high speed Inclined-plane effect is converted into this section of air and quickly moves to left, and gets rid of downwards through big arc hook, just with the projection side in duct interior air-flow direction To consistent, the power taken advantage of a situation then is strengthened again, in addition vane tip is not allow for line miscarriage product, in turn avoids any small loss, And the suitable small space of air inlet reserve chamber 11 is when blade 8 rotates, connecing spacing block 9 by smooth arc with escape pipe 6 is isolated, the chamber with Negative pressure energy reservoir function exists, and volume is big, and negative pressure is not strong enough, and small negative pressure is greatly, but to resist suction wave moment, air inlet Having fluctuated small then causes outlet fluctuation also small.Then collect three-plus-one strength at one: efficient high-pressure pressure stabilizing peripheral pump occurs. And first three is the defect of old product above.

Embodiment 2: referring to Fig. 3 Fig. 4, except escape pipe 6 and corresponding smooth arc connect spacing block 9 and become smooth concave arc spacing block 12 Curved outside the pale of civilization, remaining principle is constant.Its advantages are better than embodiment 1, and because spacing block shortens into part, blade 8 is made weekly Long with the time, the neutral gear phase is reduced, therefore air pressure is just stronger with output power.Escape pipe of going forward side by side is placed front and back both ends and is coaxially accorded with again Close installation trend.Air inlet pipe 5 is also the same, is directly entered air inlet reserve chamber 11.Image is and pipe in smooth 12 Fig. 3 of concave arc spacing block Hole reduces discount vibram outlet shape with one heart, actually should be with pore with big, and kisses and connect other than lacking, and scarce place connects at duct c (at small bore), because Bad overlapping line is expressed, therefore big to draw small representative and bore etc..

Two costs of above-mentioned implementation are as tradition.

In conclusion reaching extreme value perfection state up to energy utilization if being carefully computed and testing.
