In order to narrate conveniently, to express accurately, explain several relevant words earlier at this:
Impeller side or sidewall, casing side or sidewall that the impeller medial axis is pointed to are called axial sides or axial side wall;
Impeller and body air intake one side are axial front side, and a Dui Ying side is axial rear side with it, and axially the rest may be inferred for the denotion of the place ahead and axial rearward direction;
Radially anterior for impeller near place, impeller axle center, its anterior end is the impeller radial front end, is radially rear portion of impeller near impeller cylindrical place, and its outer circular edge is the impeller radial extremity.
The present invention, the impeller blade axial front side along impeller radially from preceding then towards impeller shaft to side axioversion gradually, the axial rear side of impeller blade along impeller radially from preceding then towards impeller shaft to side axioversion gradually.In other words, the impeller blade axial front side and axially rear side can distinguish separately separately along impeller radially from preceding then towards impeller shaft to a side (or axial the place ahead or axial rearward direction) axioversion gradually, impeller blade axial front side and axial rear side along impeller radially from preceding then gradually the axioversion direction can be the same, can be opposite, its angle of inclination can equate, can be unequal.Inboard axial rear side of air-flow path axial front side of corresponding with it impeller and impeller shaft to front side shaft backward side also be like this.
If the impeller blade axial front side along impeller radially from preceding then towards impeller shaft axioversion gradually forwards, and the axial rear side of impeller blade along impeller radially from preceding then towards impeller shaft axioversion gradually rearward, then this impeller blade just become axial both sides along impeller radially from preceding then gradually axial expansion widen structural type; If the impeller axial front side and axially rear side along impeller radially from preceding then gradually the axioversion angle equate, then the axial both sides of this impeller blade gradually axioversion position radial length equate; If the impeller blade axial front side and axially rear side radially then the axioversion angle is unequal gradually from preceding along impeller, then axioversion position radial length is unequal gradually the axial both sides of this impeller blade; The inboard air-flow path of the impeller that constitutes thus also become axial both sides along impeller radially gradually axial expansion widen structural type, its axial both sides axial expansion angle also can equate also can be unequal, its axial both sides gradually axioversion position radial length can equate also can be unequal.The impeller of this structural type also become its axial front side and axially rear side along impeller radially from preceding then respectively towards impeller shaft forwards with axial rearward direction gradually axial expansion widen, and the angle that its expansion is widened also is to equate, can be unequal.
If the impeller blade axial front side along impeller radially from preceding then towards impeller shaft axioversion gradually rearward, and the axial rear side of impeller blade along impeller radially from preceding then towards impeller shaft axioversion gradually forwards, then this impeller blade just become its axial both sides along impeller radially from the preceding axioversion structural type that narrows down gradually then.If the axial both sides of impeller blade axioversion angle gradually equate, then the axial both sides of impeller blade gradually axioversion position radial length equate that if the angle of inclination is unequal, then axioversion position radial length is unequal gradually the axial both sides of impeller blade.Inboard axial both sides of air-flow path of corresponding with it impeller and impeller shaft also are like this to both sides.
If the impeller blade axial front side along impeller radially from preceding then towards impeller shaft axioversion gradually forwards, the axial rear side of impeller blade along impeller radially from preceding then also towards impeller shaft axioversion gradually forwards, when the impeller blade axial front side gradually the axioversion angle greater than the axial rear side of impeller blade gradually during the axioversion angle, then impeller blade is radially widened structural type from preceding then the expansion gradually with regard to becoming along impeller, when the impeller blade axial front side gradually the axioversion angle less than the axial rear side of impeller blade axioversion angle gradually, then impeller blade just becomes along impeller radially from the preceding axial shrinkage structural type that narrows down gradually then, the axioversion angle is equal gradually when the axial rear side of impeller blade axial front side, and then impeller blade just becomes along impeller radially from the same uniform section structural type of preceding width then.The corresponding with it axial both sides of the inboard air-flow path of impeller, impeller shaft also will form several structural types correspondingly to both sides.
If the impeller axial front side along impeller radially from preceding then towards impeller shaft axioversion gradually rearward, the axial rear side of impeller blade along impeller along impeller radially from preceding then also towards impeller shaft axioversion gradually rearward, when the impeller blade axial front side gradually the axioversion angle greater than impeller shaft to rear side axioversion angle gradually, then impeller blade just becomes along impeller and radially then becomes gradually the axial shrinkage structural type that narrows down from preceding; When the impeller blade axial front side gradually the axioversion angle less than the axial rear side of impeller blade axioversion angle gradually, then impeller blade just become along impeller radially from preceding then gradually axial expansion widen structural type; When the axial rear side of impeller blade axial front side when the axioversion angle equates gradually, then impeller blade just becomes along impeller radially from the same uniform section structural type of preceding width then; The axial both sides of the inboard air-flow path of corresponding with it impeller, impeller shaft also will form correspondingly several structural types to both sides.
The present invention, no matter which kind of structural type impeller is, can be provided with impeller radial extremity exhaust outlet (be called for short radially exhaust outlet of impeller, its Way out can be radially, can be that radial-axial tilts) in its radial extremity.If the impeller axial front side and axially rear side along impeller radially from preceding then all to impeller shaft axioversion gradually rearward, the impeller of this structural type impeller radial extremity radially exhaust outlet Way out becomes towards impeller shaft and rearward becomes the axial-radial true dip direction, as required can with this impeller radially the exhaust outlet Way out be designed to or bias toward axial true dip direction, perhaps bias toward true dip direction radially; Axial direction relatively is convenient to several impellers (no matter be old-fashioned centrifugal blower fan blade wheel, still rear flow fan impeller or synchronous rear flow fan impeller all are suitable for) and is connected and make high pressure blower, the use of high pressure extra-high voltage gas compressor compressor.
The present invention, no matter which kind of structural type impeller shaft is to rear side, can impeller shaft be set to exhaust outlet in this axial sides, wherein with this axial sides along impeller radially from preceding forwards or axial rearward direction axioversion structural type gradually then towards impeller shaft, be more convenient for being provided with impeller shaft to exhaust outlet.With the axial rear side of impeller design Cheng Congqi along impeller radially from preceding then towards impeller shaft the place ahead or axial rearward direction axioversion structural type gradually, this axial rear side of impeller along impeller radially from preceding then towards impeller shaft forwards or the whole axioversion gradually of axial rearward direction position can become impeller shaft to exhaust outlet, promptly behind the impeller axially the side nearly all can externally discharge gaseous matter.Rear flow fan impeller and synchronous rear flow fan impeller are original just can axially discharge gaseous matter from the outlet of impeller radial extremity, if again its impeller shaft is designed to along impeller radially from preceding then towards its axial rearward direction or axial the place ahead axioversion structural type, then their axial drainage gaseous matter better effects if gradually to rear side.
Impeller shaft to rear side along impeller radially from preceding forwards or axial rearward direction axioversion gradually then towards impeller shaft, this impeller shaft can be provided with the leaf blade disk to the axioversion position of rear side, impeller blade negative pressure partitioning wall can be set, synchronous water conservancy diversion pressurized machine can be set, also the leaf blade disk be can not establish, impeller blade negative pressure partitioning wall or synchronous water conservancy diversion pressurized machine do not established.This axial rear side of impeller can all be established the leaf blade disk at whole axioversion gradually position, has perhaps both all established the leaf blade disk, all establishes impeller blade negative pressure partitioning wall or synchronous water conservancy diversion pressurized machine again, perhaps all establishes impeller blade negative pressure partitioning wall or synchronous water conservancy diversion pressurized machine; This structural type, impeller shaft is not established impeller shaft to exhaust outlet to the whole axioversion gradually of rear side position, and establishes radially exhaust outlet of impeller in the impeller radial extremity.This axial rear side of impeller can be provided with the leaf blade disk or not only establish the leaf blade disk but also establish the negative pressure partitioning wall or synchronous water conservancy diversion pressurized machine in the axioversion position gradually in part, perhaps sets up impeller negative pressure partitioning wall or synchronous water conservancy diversion pressurized machine; Its impeller shaft of this structural type is to rear side, can do not establish the leaf blade disk, do not establish impeller blade negative pressure partitioning wall or synchronously the position of axioversion gradually of water conservancy diversion pressurized machine impeller shaft is set to exhaust outlet.This axial rear side of impeller can not established the leaf blade disk at whole axioversion gradually position, does not establish impeller blade negative pressure partitioning wall or synchronous water conservancy diversion pressurized machine; This structural type, impeller shaft can all be established impeller shaft to exhaust outlet at whole axioversion gradually position to rear side.
No matter which kind of structural type impeller is in the present invention, can simultaneously not only establish impeller shaft at impeller shaft to rear side and establish radially exhaust outlet of impeller to exhaust outlet but also in the impeller radial extremity; Not only establish impeller shaft to exhaust outlet but also establish radially exhaust outlet of impeller simultaneously, and can impel impeller to have better suction effect.
Impeller of the present invention (comprises the rear flow fan impeller, the synchronous rear flow fan impeller, general old-fashioned centrifugal blower fan blade wheel) has above-mentioned multiple different structural type, radially exhaust outlet of impeller can be set, impeller shaft can be set to exhaust outlet again, can also establish simultaneously not only radially exhaust outlet but also establish impeller shaft of impeller to exhaust outlet, can make the multiple different multiple ventilator that requires uses, if with impeller shaft to front side shaft backward side make along impeller radially from preceding then jointly towards impeller shaft the place ahead or jointly towards impeller shaft axioversion structural type gradually rearward, perhaps separately with impeller shaft to rear side make along impeller radially from preceding forwards or axial rearward direction axioversion structural type gradually then towards impeller shaft, then the suitable several assembled in series of the impeller of these several structural types become high pressure blower, high pressure extra-high voltage gas compressor compressor uses.Because impeller of the present invention is axially back air draft, many by ventilator, gas compressor, the gas compressor function of this impeller assembling, purposes is wide, so be named as multifunctional synchronous after flow ventilating compressor.
Multifunctional synchronous after flow ventilating compressor, wherein, impeller shaft to rear side along impeller radially from preceding then towards impeller shaft axioversion gradually rearward, impeller shaft to front side shaft backward side along impeller radially from preceding then jointly towards impeller shaft two kinds of structural types of axioversion gradually rearward, especially suitable impeller plural serial stage is assembled into high pressure ventilator, high pressure extra-high voltage mechanism of qi, gas compressor and uses.The impeller of this structural type radially exhaust outlet Way out is the axial-radial true dip direction that biases toward axial rearward direction, impeller shaft backward side shaft to the axial air draft better effects if of exhaust outlet.The inboard air-flow path of the impeller of this structural type radially then becomes gradually axial-radial true dip direction (or day basic become axial direction) from preceding along impeller.Like this, air-flow axially enters impeller by air inlet, and the radial skew direction flows through the inboard air-flow path of impeller vertically again, then by impeller shaft backward side shaft go out impeller to the exhaust outlet axial flow.Air-flow is not to flow by axially suddenly transferring radially commutation to from start to finish in the blower fan body, and is forward to flow to a direction along impeller shaft basically.This technology is called drainage technique after the following current supercharging.
The impeller of these two kinds of structural types can several series connection be made centrifugal or centrifugal axial flow-type high pressure extra-high voltage blower, gas compressor, gas compressor use together.An impeller shaft is axially arranged to another impeller through processing to the gas that sucks again, another impeller axially sucks again, reprocessing is axially arranged to another impeller again ... do not add any static parallel works between the impeller of lontitudinal series, just can guarantee several impeller proper functioning of plural serial stage, process the high pressure extra-high voltage air-flow that needs.
High pressure blower, gas compressor are formed in the several series connection of the impeller of this axial air discharge structure form together, gas compressor uses following advantage:
1, because impeller is centrifugal, before and after the impeller axial sides along impeller radially from preceding then towards impeller shaft axioversion gradually rearward, the inboard air-flow path of impeller becomes axioversion gradually.Air-flow axially enters impeller, and sloping shaft is to flowing through impeller shaft to flowing out impeller again.In the working procedure, air-flow direction following current vertically basically flows, so the air-flow in the inboard air-flow path of impeller not only can not laterally overflow impeller, and the suction function that its flow at high speed forms can also abundant suction external substance.So the whole front axle of the impeller of this structural type is again centrifugal to side (do not establish the leaf blade disk or establish very little leaf blade disk) external intake-gas material almost in addition, so this impeller flow is big, pressurized effect is good.
2, because the inboard air-flow path of impeller forwards becomes axioversion formula gradually to axial rearward direction by impeller shaft, air flow stream influent stream overcurrent goes out (not being the direction-changing type that curves less than 90 °) that impeller is axial one-way fashion basically, whole impeller axial front side (not if establish very little frontal lobe dish), because the effect of negative pressure gap or synchronous concurrent intake grill or impeller clearance (old-fashioned centrifugal blower fan blade wheel impeller clearance) is arranged, the external intake-gas material of the whole axial front side of impeller is comprehensive all-round formula, this front axle of impeller to the side for the air-flow of discharging backward from previous impeller, no matter be oblique or horizontal, no matter be direct current or rotation, can directly fully aspirate it, do not need to put air-flow in order water conservancy diversion in impeller intake grill (even need establish middle flow guide device, it is also very little that its runner curves complications) by static flow guide device.
3, air-flow vertically by rear portion, the radially anterior middle part of first stage impeller step by step radial skew flow to the impeller radial extremity, inlet enters impeller by the impeller radial extremity, flows out impeller by impeller radial extremity outlet port again.And what impeller behind the chopped-off head radially radial extremity centrifugal force in rear portion is big, it is big that air-flow is transmitted energy.So when air-flow was discharged by rotor impeller end outlet, the volume when its volume will be than the first stage impeller import was much smaller, can dwindle several times of tens times of hundred times ..., its pressure can increase several times of tens times of hundred times ...
4, be provided with certain axial spacing space between two impellers, this pitch space is bigger than the inboard air-flow path volume of impeller, the high velocity air that axial side axial exhaust outlet is discharged diffusion (the pitch space size of fully slowing down, should look actual demand suitably is provided with), do not need to be provided with specially deceleration diffusion facility between two impellers in other words, just can make high velocity air after the previous Impeller Machining diffusion that slowed down fully.
5, because impeller is directly axially to discharge to air-flow, be again directly axially to aspirate, in the course of working, if desired to the high pressure-temperature gas cooling of lowering the temperature in the processing, can between impeller, directly add the cooling cooling infrastructure, allow high pressure-temperature air-flow after the previous Impeller Machining directly axially arrange and continue to give processing in a back impeller.
6, impeller shaft to rear side and axial front side along impeller radially from preceding then towards impeller shaft axioversion structural type gradually rearward, the impeller axial front side, both therebetween the position add the leaf blade disk make its radially the middle part radially rear axle to the intake-gas material, again can its radially the middle part radially the rear portion add the leaf blade disk and therebetween the position add impeller intermediate dedicated intake grill, make impeller intermediate dedicated intake grill axially aspirate external substance.Air-flow radially radially axially enters impeller in the middle part in the rear portion by the impeller front axle to the side, axially discharges impeller thereafter again, and airflow path curves tortuous few, and frictional loss is little, thereby the rotor power consumption is few, the efficient height.Air-flow axially enters impeller by the impeller front axle to side impeller intermediate dedicated intake grill, flow through axial-radial, thereafter axially discharge impeller in rear portion (near impeller radial extremity position) backward by footpath, axial side behind the impeller again, air-flow radially flow process is big, single-stage impeller pressurized effect is good, because like this, the impeller progression of series connection just can lack, thereby the rotor axial size just can shorten.
7, because impeller is directly axially suction to air-flow, be again directly axially to discharge, between two impellers, add static parallel works if desired, its structure can be very simple, as the guide ring that keeps out the wind, only just individual conically shaped structural type, its expansion end to rear side, are accepted the air-flow that previous impeller shaft is come to rear side row towards previous impeller shaft; Its serrated end towards a back impeller front axle to the side, with keep out the wind guide ring by previous impeller receive the air flow guiding of coming in a back impeller front axle to side impeller inlet (impeller negative pressure gap, synchronous concurrent intake grill, impeller intermediate dedicated intake grill), as required, can make the water conservancy diversion serrated end outlet water conservancy diversion that keeps out the wind in the position that a back impeller front axle needs arbitrarily to the side, as radially rear end, footpath rear portion, radially rear portion, radially middle part, positions such as front portion, impeller intermediate dedicated intake grill radially backward.
In a word, behind the impeller axially the side along impeller radially by preceding then towards impeller shaft axioversion gradually rearward, behind the impeller axially side and front axle to the side along impeller radially by preceding then jointly towards impeller shaft high pressure blower, gas compressor, the gas compressor formed of the impeller of two kinds of structural types of axioversion gradually rearward, in the entire work process, air-flow curves less tortuous, flow process is short, frictional loss is little, thereby they are will pressurized effect good, the efficient height, save the energy, noise is low.
Compare with old-fashioned centrifugal-flow compressor gas compressor, old-fashioned axial-flow compressor gas compressor with general axial fan (comprising old-fashioned diagonal flow type, mixed flow fan), multifunctional synchronous after flow ventilating compressor of the present invention is simple in structure, and volume is little, and materials are few, in light weight, carrying and installation is convenient, saves resource, and pressurized effect is good, the efficient height, save the energy, noise is low, helps environmental protection.
The present invention had both suited to be assembled into the centrifugal fan blower, the axial fan blower uses, and adapted to again to be assembled into centrifugal-flow compressor gas compressor, the use of axial-flow compressor gas compressor.
Casing intake grill of the present invention place can also be provided with from preceding then (casing intake grill, diffusion shunt, its air intake is a front end, its outlet air end is the rear end) become the diffusion shunt of expansion structure form, the diffusion shunt is provided with the connection guide plate, and the diffusion shunt connects with casing intake grill sidewall by connecting guide plate.
Here the casing of saying is meant centrifugal blower casings such as spirality, cylinder barrel shaped taper barrel combined type, circular cone tube spiral case combined type, scroll casing shape; So-called casing intake grill is meant this centrifugal fan intake grill; So-called casing intake grill place is meant casing intake grill outlet outside, the inside and outside place of casing intake grill outlet, the inboard place of casing intake grill etc.Spread in other words shunt can be located at the casing intake grill outlet end outside over against and press close to casing intake grill place, can be located at the inside and outside place of casing intake grill outlet, can be located at casing intake grill inboard.
The diffusion shunt can be the cone structure form, can be the evenly multiple structural type of diffusion profile air-flow such as spherical, segment shape.The function of diffusion shunt, the one, with the gaseous matter by the casing intake grill vertically radially following current evenly spread inboard air-flow path of each impeller that impeller is given in shunting, avoid the air-flow vertical impact impeller of coming and form fierce eddy current by the casing intake grill, thereby can raise the efficiency, reduce noise.The 2nd, with the material by the casing intake grill vertically radial skew evenly spread shunting and (be front portion radially for the impeller radial extremity near place, impeller axle center, near impeller cylindrical place is radially rear portion of impeller, the impeller outer rounded edge is a radial extremity), avoid entering the impeller inboard by gas, liquid, the solid matter of casing intake grill, and can avoid producing fierce eddy current, thereby just improved efficient, reduced noise.
Here the casing intake grill of saying can be a cylindrical drum structural type, can be the structural type that then becomes expansion from preceding, wherein best with the expansion structure form, because the casing intake grill sidewall of expansion structure form is followed the axial-radial tilting air-flow path that forms by between the preceding diffusion shunt that then becomes to expand, the air-flow that more helps in the casing intake grill forms axial-radial inclination diffusion flowing state.
The present invention can also be provided with the drainage diffuser that then becomes expanssion type from preceding laterally at impeller shaft.Here the impeller shaft of saying is meant leaf blade disk, impeller blade negative pressure partitioning wall, synchronous water conservancy diversion pressurized machine, impeller blade axial edge, impeller intermediate dedicated intake grill, impeller shaft position, space laterally laterally.The drainage diffuser can be located on the impeller axial side wall and (comprise leaf blade disk, impeller blade axial edge etc.) in other words, can be located in the impeller intermediate dedicated intake grill, can be located at the impeller jack shaft and wait the place laterally.
The axial rear end of impeller drainage diffuser connects with impeller, thisly is connected with direct connection and is connected two kinds of Connecting format indirectly.Directly connect is exactly that drainage diffuser rear end directly connects with impeller; Connecting indirectly is exactly that drainage diffuser rear end will be provided with the drainage device link, and the drainage diffuser connects with impeller by the drainage device link.
The drainage diffuser then becomes expanded form (its air intake of drainage diffuser is a drainage diffuser front end by preceding, its outlet end is drainage diffuser rear end), its expansion scope can be expanded arbitrarily between 0 °-180 °, adopts much angles of flare, can be decided according to the actual requirements.The drainage diffuser can adopt the structural type of multiple one-tenth expanssion type, as the even multiple structural type of diffusion profile air-flow such as taper tubular, taper shape, spherical crown shape, segment shape.
The function of drainage diffuser is the same with the effect of diffusion shunt, the one, the air-flow that air inlet is brought is by axially changing into the axial-radial true dip direction, diffusion profile gives each impeller of impeller inboard air-flow path, the great eddy current loss of avoiding producing fierce eddy current and causing, thereby just can raise the efficiency, reduce noise.The 2nd, the gas that the casing intake grill is brought, liquid, solid matter radial skew vertically evenly spread shunting and give the impeller radial extremity, avoid the various material contact impellers of coming in or enter the impeller inboard by the casing intake grill, and can avoid producing fierce eddy current, thereby can raise the efficiency, reduce noise.
