A kind of centrifugal pump, contained by sealing, the common mechanical single seal for having compressed spring, as section is illustrated Shown in the sealing (7m) of Figure 32, contain rotating ring, stationary ring and auxiliary seal ring and compression spring；One end of the compression spring is equipped with rotating ring ；And the other end of compression spring is equipped with stationary ring and auxiliary seal ring, axial compressive force is larger；For wear reduction, the rotating ring uses Impregnating resin graphite, the stationary ring silicon carbide reaction-sintered, the auxiliary seal loop material are fluorubber, and described Compression spring be dextrorotation, and be stainless steel, such as the SUS316 trades mark.

With improvement, for the larger present situation of the axial compressive force for improveing the common compressed spring mechanical single seal of direct-connected water pump, Consider and reform spiral labyrinch seal also to cry composite straight-through shape helixseal, be machined with respectively on axis surface and set internal face The opposite multiple thread in direction, the tooth of internal and external threads crossing across gap.When shaft rotation is moved, fluid is in oppositely oriented spiral shell Eddy generation friction between rotation generates pressure head and overcomes leakage.Rotating speed is higher, and leakage rate is fewer, and it is suitable for low viscosity fluids； Should on the basis of be further improved to contain the even rotation labyrinth seal in two-way left and right, and with addition of static also sealable O-ring seal, For water pump.It is to contain the even rotation labyrinth seal structure in two-way left and right and can be also salable with addition of static state referring to Figure 26 and Figure 27 O-ring seal the centrifugal pump drive shaft (7), be equipped on its axis surface the even rotation spiral in two-way left and right (7m1, 7m2)；In the centre of the even rotation spiral (7m1,7m2) in two-way left and right, it is equipped with and places seal groove (7m3)；Described puts It is U-shaped or semicircle to set seal groove (7m3), to put O-ring seals, certainly, it is also possible to other types such as Y types or L-type it is close Seal is to adapt to static also sealable situation, and the placement seal groove can also be placed on the other positions of axis.Described The even rotation spiral (7m1,7m2) in two-way left and right that the axis surface of the drive shaft (7) of centrifugal pump is equipped with, is two-way, negative direction , a first from left is right, that is to say, that if the first spiral (7m1) on the axis is left-handed, it is coaxial on Second spiral (7m2) is then dextrorotation；It is used as clearance fit simultaneously, because the drive shaft (7) of the centrifugal pump is to pass through sealing And bearing, while being inserted into and across the vertical shell (8), and being deep into the outer housing of pump, and set in the outer housing of pump In the spiral case (6) having, and keep the impeller (5) for the other end for being located at drive shaft (7) high-speed rotating, therefore In hole in the vertical shell (8), as the set internal face with the mutual clearance fit in axis surface, it is also correspondingly provided with direction phase Anti- multiple thread or one start screw；If the first spiral (7m1) on axis is left-handed, what is matched therewith is described vertical outer The opposite multiple thread or list in the direction that is equipped with as the set internal face with the mutual clearance fit in axis surface in hole in shell (8) Head thread is dextrorotation, while the second spiral (7m2) on axis is dextrorotation, then in the vertical shell (8) to match therewith Hole in the opposite multiple thread or one start screw in the direction that is equipped with as the set internal face with the mutual clearance fit in axis surface be Left-handed；If the first spiral (7m1) on axis is dextrorotation, conduct in the hole in the vertical shell (8) that matches therewith The multiple thread or one start screw opposite with the direction that the set internal face of the mutual clearance fit in axis surface is equipped be it is left-handed, together When axis on the second spiral (7m2) be left-handed, then in the hole in the vertical shell (8) to match therewith as with axis table Direction that the set internal face of the mutual clearance fit in face is equipped with opposite multiple thread or one start screw are dextrorotation；In favor of subtracting Few axial force and attrition.

The shell of the direct-connected water pump, such as Figure 12, Figure 13, Figure 14, shown in Figure 15, water outlet is placed in the middle, and its middle part Water inlet is equipped with multiple ribs, to play booster action；But because not being fusiform, so all having certain resistance to smoothness water outlet Stagnant effect.

With improvement, the shell (4) of the pump, as shown in Figures 2 and 3, water outlet (4b) be not placed in the middle, but biases And it is close to volute outlet side, so that outlet passage is simpler and more direct and smooth；In the water outlet of the shell (4) of the pump On (4b), internal thread is remained with to connect external pipe thread；On the water outlet (4b) of the shell (4) of the pump, it is equipped with convex Land (4d) and concave ring groove (4e) more easily coordinate quick coupling with profit；The middle part of the shell (4) of the pump into The mouth of a river is equipped with multiple ribs, to play booster action；But because not being fusiform, so all thering is certain retardance to make smoothness water outlet With；As an improvement, multiple ribs are changed to multiple streamlined ribs；The water inlet at the middle part of the shell (4) of the pump, if There are multiple streamlined ribs (4a), the outer end of each of which rib is parabola shaped i.e. fusiform circular arc, and multiple streamlineds The arrangement of rib is slightly in the zigzag of ring circumference, and zigzag ring circumferential direction is the direction along water outlet, as shown in Fig. 2, described Streamlined rib also play booster action, and because being fusiform, so all reducing retardation to smoothness water outlet.

The spiral case of the pump is equipped with 2 water outlets, because two water outlet is section, is discharged just easily in unexpected section And form vortex.As an improvement, as illustrated in figs. 8-11, the spiral case (6) of the pump is equipped with down in two water outlet Angle (6a), the vortex that water outlet reduces unexpected section and formed with regard to smoother；The spiral case, preferably with the Northern Hemisphere inverse time The spiral case of non-Archimedes's function line of needle flow direction further increases effect with profit and reduces linear loss.

The blade (5k) of the direct-connected water pump is equipped with 4 leaves as shown in Figure 22, Figure 23, Figure 24, Figure 25 on disk The thickness of piece, blade is the same, that is each the distance between blade front arc and the rear arc i.e. thickness of blade are not Pipe radius size is but just as thick, and this is unfavorable, because the stress of blade at more outer i.e. bigger radius is increasing, And flow accelerates outward, should more lean on outer leafs it is thicker better；The length of 4 blades differs, and shakes to put more energy into stir.

For the present invention to pumping the major contribution of class, it is parabolic letter that it is disk plane, interior concave bottom that there is provided one kind containing both ends Number faces and blade both sides be have angle gradually open function face and blade both sides be interior thin and outer thickness function impeller, with sharp reduction Fluid friction losses and vortex.Referring to Figure 16, this is the sectional view of the function impeller；The main body for forming impeller is in having The disk in heart hole and multiple blades；The centre bore is equipped with drive shaft, and mutually hangs down with disk end flat, is driven with profit；Institute The both ends for the disk stated are planes together with the both ends for the disk plane of the blade being located at thereon circumferentially rotated, and are both convenient for Processing, and it is convenient for two plane plane with the plane of the inside of adjacent close spiral case and with the inside of vertical shell respectively Close to being coordinated the geometric tolerance for being easily achieved ideal clearance fit and assembly in a manner of the ingratiating with of plane by plane；Described The plane towards water inlet of disk, cutouts material make into indent, and interior concave bottom is parabolic function face, in favor of dishing out Internal losses in fluid and reduction flow path；And take (such as 1- also more slightly higher than the plane towards water inlet of the disk Transverse plane of another parallel plane as blade 5mm), the other end of blade and the interior concave bottom in parabolic function face and disk are flat Face connects；The blade both sides are higher order functionality face or angle involute or the angle parabola for having angle, or There is the archimedes line of angle, it is thinner closer to the center of circle and thicker i.e. interior thin further away from the center of circle and outer thickness to form blade both sides, The disk of interior concave bottom of the blade equipped with parabolic function face of multiple interior thin and outer thickness is with regard to formation function impeller.

The pump of different model, flow Q is different, and lift H is different, therefore the number of blade should select to be preferred, can be by practical examination It tests to select.To the pump for requiring flow larger and lift is not high, the influence of the number of blade and form is smaller, but existing influences； The especially more impeller of blade quantity, the vortex of vacuum side of blade negative pressure is smaller, but blade is overstocked, and friction surface increases, also Increase friction loss.And flow is smaller and the higher pump of lift to requiring, the influence of the number of blade and form is just larger, especially Be the liquid to such as silt containing solid and the pump for easily blocking impeller intake, because its blade quantity is on the low side, generate negative pressure and The possibility in hole is with regard to larger, therefore its operational efficiency is just more lower.The flow of pump, lift, the number of blade, and outlet peace The parameters such as angle are put to interact.It is type selecting or the reference data that work is tested below.

The blade (5y) of function impeller (5a) as shown in figure 17 is 4, about 20 degree of the angle of outlet；

The blade (5y) of function impeller (5b) as shown in figure 18 is 5, about 23 degree of the angle of outlet；

The blade (5y) of function impeller (5c) as shown in figure 19 is 6, about 25 degree of the angle of outlet；

The blade (5y) of function impeller (5d) as shown in figure 20 is 7, about 27 degree of the angle of outlet；

The blade (5y) of function impeller (5e) as shown in figure 21 is 8, about 28 degree of the angle of outlet.

With improvement, the blade both sides are higher order functionality face or the angle involute face for having angle, are 3 degree；Or It is angle parabola face, is 2 degree；Or have the archimedes line face of angle, for 1 degree or certain is two different for example The combination of involute and parabolical angle 1-5 degree, it is thinner and thicker further away from the center of circle closer to the center of circle to form blade both sides Thin and outer thick in i.e., the disk of interior concave bottom of the blade equipped with parabolic function face of multiple interior thin and outer thickness is with regard to formation function Impeller；But the vane thickness of the most thin place of inner terminal is it is noted that intensity, is in general advisable with being not less than 1mm.

Specific implementation mode

In order to make up the big phenomenon of noise caused by the existing mechanism of pump, provided by the invention a kind of for engine In the catalase hush tube loading machine containing aluminium dioxide of improvement, exhaust gas is made to pass through muffler ASSY and catalyst hush tube (69), then By the entire protective cover for covering pump for having noise elimination to act on, and it is discharged from its gap or aperture gap.Entire centrifugal pump, or even It is blow molded shell, liner foamed plastics with the protective cover of engine together outer cover, or with bilayer, or uses other materials.

Because the present invention relates to a kind of field, building site, garden, park and road sides etc. of being suitable for without the centrifugation used in electric field Pump, belongs to the water pump class of universal machine product, especially a kind of that driving machine, such as engine is used especially to contain inside spin whirlpool and spray Single-cylinder air-cooled petrol engine 139F types of mini four-stroke of the carburetor of mouth or with the carburetor containing inside spin whirlpool nozzle It is containing both ends with what the single-cylinder air-cooled petrol engine 1E34 types of small two-stroke of the more scavenging ports of improvement carried out direct connection high speed drive Disk plane, interior concave bottom are parabolic function face and blade both sides are that gradually to open function face and blade both sides be interior thin and outer thick Impeller, and containing the even rotation labyrinth seal in two-way left and right, and containing eccentric outlet and the Northern Hemisphere counterclockwise to streamlined rib Shell, and containing outlet chamfering and Northern Hemisphere counter clockwise flow to non-Archimedes's function line spiral case centrifugal pump；Or Perhaps it can be said that having started a kind of has swirl sprayer engine direct to be associated with the new of high speed function impeller and the centrifugal pump in even rotation labyrinth Technical field.

Engine direct connected centrifugal pump is widely used in the nothings such as field, building site, garden, park and road side because its is portable Electric field institute.Its low vibration and low noise can have certain curative effect if considering the foamed plastics of the plus-minus vibration around；And it vibrates Very big root with noise is the harmony of mechanism and engine not only in the precision and geometric tolerance of power and pump Cooperation, it is in fact a hard nut to crack left for a long time to pursue the low vibration of pump and low emission.Using two stroke engine 50% or more power per liter can be improved relative to four-stroke engine, but to be taken measures in discharge, this is the one of the present invention Part project；Engine direct connected centrifugal pump is portable dam, it is desirable to power light and small；If with four-stroke engine contribute compared with It is few；Volume is big if with booster；The easy soiled person if with diesel engine.Since engine direct connected centrifugal pump come out with Come, the structure of the core component impeller of work is just established always on the theoretical foundation assumed at one, and impeller is exactly made Blade quantity is infinitely more, and the thickness of blade is infinitely small, to eliminate vortex of the water in impeller；But practical charging pump is inefficient Rate is existing for gram sight.The shell of traditional direct-connected water pump, such as Figure 12, Figure 13, Figure 14, shown in Figure 15, water outlet is placed in the middle, And multiple ribs of its middle part water inlet are not fusiform, so all having certain retardation to smoothness water outlet.Traditional is straight Join the spiral case of water pump, two water outlet is section, if plus chamfering, water outlet is just smoother, and reduces unexpected section and is formed Vortex.The blade of traditional direct-connected water pump, as shown in Figure 22, Figure 23, Figure 24, Figure 25, the thickness of blade be it is the same, This is unfavorable, and the stress of blade is increasing at more outer i.e. bigger radius, and flow accelerates outward, Ying Yue It is thicker better by outer leafs.The pump shaft of traditional direct-connected water pump is on long flange as shown in Figure 29, Figure 30, Figure 31 Two external flanges for being bolted engine output shaft, additional rotary inertia is big, and easily head tremor is put partially.Traditional direct connection Water pump often uses compressed spring mechanical single seal, axial compressive force larger.Also composite straight-through shape spiral is also in spiral labyrinch seal Sealing, on axis surface and the set internal face multiple thread that be machined with direction respectively opposite, the tooth of internal and external threads is across gap intersection It.When shaft rotation is moved, fluid eddy generation friction between oppositely oriented spiral generates pressure head and overcomes leakage.Rotating speed is higher, Leakage rate is fewer, and it is suitable for low viscosity fluids；If being further improved on this basis close to contain the even rotation labyrinth in two-way left and right Envelope, and with addition of static also sealable O-ring seal or other types of mainly static sealing ring, also can be used for water pump On.

Shortcoming caused by it can make up the mechanism of existing water pump makes the low vibration of water pump and low noise be improved, carries High output and outlet effect lower discharge, and the present invention provides a kind of improvement of water pump, are that a kind of novel swirl sprayer starts Machine direct connection has high speed function impeller and the centrifugal pump in even rotation labyrinth, is a kind of driving machine, and such as engine especially contains interior The single-cylinder air-cooled petrol engine 139F types of mini four-stroke of the carburetor of spiral vortex nozzle or with contain inside spin whirlpool nozzle Carburetor and that improves that the single-cylinder air-cooled petrol engine 1E34 types of small two-stroke of more scavenging ports come that direct connection high speed drives contain Both ends are that disk plane, interior concave bottom are parabolic function faces and blade both sides are that gradually to open function face and blade both sides be interior thin And outer thick impeller, and containing the even rotation labyrinth seal in two-way left and right, and containing eccentric outlet and the Northern Hemisphere counterclockwise to streamline The shell of shape rib, and containing outlet chamfering and Northern Hemisphere counter clockwise flow to non-Archimedes's function line spiral case from Heart pump.Entire centrifugal pump also outer cover is blow molded shell, liner foamed plastics with bilayer.Because being associated with high speed in swirl sprayer engine direct On function impeller and the centrifugal pump in even rotation labyrinth, engine is improved, impeller seals, shell, spiral case, therefore emission reduction reinforcement, has Protective cover is more convenient for noise reduction, and multinomial measure improves the environmental protection quality and usability of centrifugal pump.

A kind of centrifugal pump, contained by sealing, the common mechanical single seal for having compressed spring, as section is illustrated Shown in the sealing (7m) of Figure 32, contain rotating ring, stationary ring and auxiliary seal ring and compression spring；One end of the compression spring is equipped with rotating ring ；And the other end of compression spring is equipped with stationary ring and auxiliary seal ring, axial compressive force is larger；For wear reduction, the rotating ring uses Impregnating resin graphite, the stationary ring silicon carbide reaction-sintered, the auxiliary seal loop material are fluorubber, and described Compression spring be dextrorotation, and be stainless steel, such as the SUS316 trades mark；The axial compressive force perseverance of compression spring end face seal has.

With improvement, for the larger present situation of the axial compressive force for improveing the common compressed spring mechanical single seal of direct-connected water pump, Consider and reform spiral labyrinch seal also to cry composite straight-through shape helixseal, be machined with respectively on axis surface and set internal face The opposite multiple thread in direction, the tooth of internal and external threads crossing across gap.When shaft rotation is moved, fluid is in oppositely oriented spiral shell Eddy generation friction between rotation generates pressure head and overcomes leakage.Rotating speed is higher, and leakage rate is fewer, and it is suitable for low viscosity fluids； Should on the basis of be further improved to contain the even rotation labyrinth seal in two-way left and right, and with addition of static also sealable O-ring seal, For water pump.It is to contain the even rotation labyrinth seal structure in two-way left and right and can be also salable with addition of static state referring to Figure 26 and Figure 27 O-ring seal the centrifugal pump drive shaft (7), be equipped on its axis surface the even rotation spiral in two-way left and right (7m1, 7m2)；In the centre of the even rotation spiral (7m1,7m2) in two-way left and right, it is equipped with and places seal groove (7m3)；Described puts It is U-shaped or semicircle to set seal groove (7m3), to put O-ring seals, certainly, it is also possible to other types such as Y types or L-type it is close Seal is to adapt to static also sealable situation, and the placement seal groove can also be placed on the other positions of axis.Described The even rotation spiral (7m1,7m2) in two-way left and right that the axis surface of the drive shaft (7) of centrifugal pump is equipped with, is two-way, negative direction , a first from left is right, that is to say, that if the first spiral (7m1) on the axis is left-handed, it is coaxial on Second spiral (7m2) is then dextrorotation；It is used as clearance fit simultaneously, because the drive shaft (7) of the centrifugal pump is to pass through sealing And bearing, while being inserted into and across the vertical shell (8), and being deep into the outer housing of pump, and set in the outer housing of pump In the spiral case (6) having, and keep the impeller (5) for the other end for being located at drive shaft (7) high-speed rotating, therefore In hole in the vertical shell (8), as the set internal face with the mutual clearance fit in axis surface, it is also correspondingly provided with direction phase Anti- multiple thread or one start screw；If the first spiral (7m1) on axis is left-handed, what is matched therewith is described vertical outer The opposite multiple thread or list in the direction that is equipped with as the set internal face with the mutual clearance fit in axis surface in hole in shell (8) Head thread is dextrorotation, while the second spiral (7m2) on axis is dextrorotation, then in the vertical shell (8) to match therewith Hole in the opposite multiple thread or one start screw in the direction that is equipped with as the set internal face with the mutual clearance fit in axis surface be Left-handed；If the first spiral (7m1) on axis is dextrorotation, conduct in the hole in the vertical shell (8) that matches therewith The multiple thread or one start screw opposite with the direction that the set internal face of the mutual clearance fit in axis surface is equipped be it is left-handed, together When axis on the second spiral (7m2) be left-handed, then in the hole in the vertical shell (8) to match therewith as with axis table Direction that the set internal face of the mutual clearance fit in face is equipped with opposite multiple thread or one start screw are dextrorotation；Therefore it is conducive to subtract How high few axial force and attrition because being clearance fit, therefore its precision of each spiral and do not have to, are easy to mould.

The shell of the direct-connected water pump, such as Figure 12, Figure 13, Figure 14, shown in Figure 15, water outlet is placed in the middle, and its middle part Water inlet is equipped with multiple ribs, to play booster action；But because not being fusiform, so all having certain resistance to smoothness water outlet Stagnant effect.There are individual damaged ability ribbeds when originally without rib.

With improvement, the shell (4) of the pump, as shown in Figures 2 and 3, water outlet (4b) be not placed in the middle, but biases And it is close to volute outlet side, therefore be conducive to the simpler and more direct smoothness of outlet passage；In the water outlet of the shell (4) of the pump On (4b), internal thread is remained with to connect external pipe thread；On the water outlet (4b) of the shell (4) of the pump, it is equipped with convex Land (4d) and concave ring groove (4e) more easily coordinate quick coupling with profit；The middle part of the shell (4) of the pump into The mouth of a river is equipped with multiple ribs, to play booster action；But because not being fusiform, so all thering is certain retardance to make smoothness water outlet With；As an improvement, multiple ribs are changed to multiple streamlined ribs；The water inlet at the middle part of the shell (4) of the pump, if There are multiple streamlined ribs (4a), the outer end of each of which rib is parabola shaped i.e. fusiform circular arc, and multiple streamlineds The arrangement of rib is slightly in the zigzag of ring circumference, and zigzag ring circumferential direction is the direction along water outlet, as shown in Fig. 2, described Streamlined rib also play booster action, and because being fusiform, so all reducing retardation to smoothness water outlet.

The spiral case of the pump is equipped with 2 water outlets, because two water outlet is section, is discharged just easily in unexpected section And form vortex.As an improvement, as illustrated in figs. 8-11, the spiral case (6) of the pump is equipped with down in two water outlet Angle (6a), the vortex that water outlet reduces unexpected section and formed with regard to smoother；The spiral case, preferably with the Northern Hemisphere inverse time The spiral case of non-Archimedes's function line of needle flow direction further increases effect with profit and reduces linear loss.Because on the Northern Hemisphere, Influenced by earth rotation and the coriolis force of revolution, vortex be mostly counter clockwise flow to.Unless pump is used in the Southern Hemisphere.

The blade (5k) of the direct-connected water pump is equipped with 4 leaves as shown in Figure 22, Figure 23, Figure 24, Figure 25 on disk The thickness of piece, blade is the same, that is each the distance between blade front arc and the rear arc i.e. thickness of blade are not Pipe radius size is but just as thick, and this is unfavorable, because the stress of blade at more outer i.e. bigger radius is increasing, And flow accelerates outward, and it should be more leaning on outer leafs thicker better, still intensity, does not have an effect on the vortex drag of vacuum side of blade.

For the present invention to pumping the major contribution of class, it is parabolic letter that it is disk plane, interior concave bottom that there is provided one kind containing both ends Number faces and blade both sides be have angle gradually open function face and blade both sides be interior thin and outer thickness function impeller, with sharp reduction Fluid friction losses and vortex.Referring to Figure 16, this is the sectional view of the function impeller；The main body for forming impeller is in having The disk in heart hole and multiple blades；The centre bore is equipped with drive shaft, and mutually hangs down with disk end flat, is driven with profit；Institute The both ends for the disk stated are planes together with the both ends for the disk plane of the blade being located at thereon circumferentially rotated, and are both convenient for Processing, and it is convenient for two plane plane with the plane of the inside of adjacent close spiral case and with the inside of vertical shell respectively Close to being coordinated the geometric tolerance for being easily achieved ideal clearance fit and assembly in a manner of the ingratiating with of plane by plane；Described The plane towards water inlet of disk, cutouts material make into indent, and interior concave bottom is parabolic function face, in favor of dishing out Internal losses in fluid and reduction flow path；And take (such as 1- also more slightly higher than the plane towards water inlet of the disk Transverse plane of another parallel plane as blade 5mm), the other end of blade and the interior concave bottom in parabolic function face and disk are flat Face connects；The blade both sides are higher order functionality face or angle involute or the angle parabola for having angle, or There is the archimedes line of angle, it is thinner closer to the center of circle and thicker i.e. interior thin further away from the center of circle and outer thickness to form blade both sides, The disk of interior concave bottom of the blade equipped with parabolic function face of multiple interior thin and outer thickness is with regard to formation function impeller.Many institute's weeks Know, hydrokinematics has speed with dynamic (dynamical) primary amount, and acceleration, density, surface force is containing pressure and frictional force, mass force Containing gravity and various inertia force etc..In addition to density is scalar, above is all vector.From the fortune of the analysis each independent particle of fluid The dynamic movement for setting about studying entire fluid, also known as Lagrangian method.And from analysis moving fluid occupied by motionless space In each fixed point fluid particle movement sets about is Euler method.Due to the increasingly complex difficulty of the functional expression of Laplace method, thus it is more The movement of fluid is analyzed with Euler method.There is local acceleration in flow field when being unstable field；And flow field be uneven flow field when have Migrate acceleration.Theoretical (Eular) head equation when Euler's impeller vane of centrifugal pumps is unlimited more shows the theoretical pressure that impeller generates The rotating speed of head and impeller leaf road entrance, the geometry of exit blade, speed and impeller is related.Because with parabolic indent with it is double Side angle blade just makes flow path in the region among from blade inlet to blade broaden, reduces the internal losses in flow path, Thus excellent impeller performance is obtained when the ratio speed of receded disk impeller is smaller；And export smaller, make fluid Non- even shear stress is reduced.

The pump of different model, flow Q is different, and lift H is different, therefore the number of blade should select to be preferred, can be by practical examination It tests to select.To the pump for requiring flow larger and lift is not high, the influence of the number of blade and form is smaller, but existing influences； The especially more impeller of blade quantity, the vortex of vacuum side of blade negative pressure is smaller, but blade is overstocked, and friction surface increases, also Increase friction loss.And flow is smaller and the higher pump of lift to requiring, the influence of the number of blade and form is just larger, especially Be the liquid to such as silt containing solid and the pump for easily blocking impeller intake, because its blade quantity is on the low side, generate negative pressure and The possibility in hole is with regard to larger, therefore its operational efficiency is just more lower.The flow of pump, lift, the number of blade, and outlet peace The parameters such as angle are put to interact.It is type selecting or the reference data that work is tested below.

The blade (5y) of function impeller (5a) as shown in figure 17 is 4, about 20 degree of the angle of outlet；

The blade (5y) of function impeller (5b) as shown in figure 18 is 5, about 23 degree of the angle of outlet；

With improvement, the blade both sides are higher order functionality face or the angle involute face for having angle, are 3 degree；Or It is angle parabola face, is 2 degree；Or have the archimedes line face of angle, for 1 degree or certain is two different for example The combination of involute and parabolical angle 1-5 degree, it is thinner and thicker further away from the center of circle closer to the center of circle to form blade both sides Thin and outer thick in i.e., the disk of interior concave bottom of the blade equipped with parabolic function face of multiple interior thin and outer thickness is with regard to formation function Impeller；But the vane thickness of the most thin place of inner terminal is it is noted that intensity, is in general advisable with being not less than 1mm.

With improvement, it in order to cut off the long filament for infiltrating liquid, is effectively pushed also for blade is cut with making the less resistance of liquid Face, in the most thin place of the blade inner terminal, referring to Figure 17 and Figure 18, if cutting edge angle (5f), in general blade angle exists 45 degree or so, acute angle is taken by the material of the long filament to be cut, to be advisable not less than 10 degree that is, the blade is most interior The blade angle of the most thin place cutting edge angle (5f) at end is between 10-45 degree.

In centrifugal pump operational process, since liquid is to enter impeller under low pressure, and flow out under high pressure, therefore make impeller Both sides pressure differs, and produces the axial thrust for being directed toward Way in, can cause rotor that axial float occurs, and generates mill Damage and vibration, in addition to setting axial thrust bearing, can also improve impeller and carry out balancing axial thrust, such as use double-suction type, or use balance hole Or balance pipe.Here using the method for balance blade；It is described have the mutliblade impeller disk not towards the back of the body of water inlet Face is cast with several radial rib pieces, and the fluid in muscle piece impeller back gap accelerates rotation, increases centrifugal force, and makes impeller Backside pressure reduces；With improvement, it is described have the mutliblade impeller disk not towards the back side of water inlet, both below than the back side End face it is slightly higher, such as 1-5mm, if several blades as positive leaf morphology, in blade impeller back gap Fluid accelerate rotation, increase centrifugal force, and make wheel backface pressure significantly reduce.It is further used as improving, it is close using end face The method of envelope considers and reforms spiral labyrinch seal, is not located on axis, is located at the surface and therewith of wheel backface Close to vertical shell inner wall surface on, be machined with the planar spiral groove of the opposite bull in direction respectively, such as use Archimedes Class helix；When the impeller disk rotates, fluid eddy generation friction between oppositely oriented spiral generates pressure head and overcomes anti-work Firmly and anti-leak；Rotating speed is higher, and leakage rate is fewer, and it is suitable for low viscosity fluids；It can also be further improved on this basis It is combined for various end face left-and-right spirals, existing end face labyrinth seal has the double action of longitudinal balance again.
