Description
Technical field
The utility model relates to guide-vane for fan technical field more particularly to a kind of exit guide vanes.
Background technique
The axial flow blower big for output pressure generally will be fitted with exit guide vane in face after the impeller.Exit guide vane is
Exducer, it is a kind of diffuser grid, and effect is the deflection air-flow cycle axial direction outflow impeller, while will deflect gas
The kinetic energy of stream is changed into static energy.Traditional exit guide vane includes cylinder and more blades, and blade is fixedly arranged on the excircle of cylinder
On surface, but the structure of this exit guide vane is built on the sand, and blade is easily damaged.And since the design of blade is unreasonable, cause to increase
Press effect undesirable.
Therefore, it is urgent to provide a kind of exit guide vanes, so as to solve the deficiencies in the prior art.
Utility model content
The utility model aim is, for a kind of exit guide vane that the prior art is insufficient and provides.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is as follows:
A kind of exit guide vane, including cylinder and more blades, the blade are uniformly fixedly arranged on the outer circle weekly form of the cylinder
It further include clamping ring on face, the blade is fixedly arranged between the clamping ring and the cylinder；The top of the blade is equipped with more
A fixing lug boss, the fixing lug boss are embedded in the clamping ring；The blade is arc shaped blade, and the radian of the blade is
0.8Rad-1.1Rad；The ratio of the height of the radius of the cylinder and the blade is 1:0.7~1:0.9.
More preferably, hollow part is equipped in the cylinder.
More preferably, the middle part of the cylinder is equipped with the first mounting hole.
More preferably, the clamping ring is annular in shape, and mounting circular ring, the peace are equipped on the edge at the clamping ring both ends
It fills annulus and is equipped with multiple second mounting holes.
More preferably, the quantity of the blade is prime number.
The utility model has the following beneficial effects: the blade of the exit guide vane is fixedly arranged between clamping ring and cylinder, blade is solid
It is fixed more firm；The top of blade is equipped with multiple fixing lug boss, and fixing lug boss is embedded in clamping ring, further fixes blade；Blade
For arc shaped blade, the radian of blade is 0.8Rad-1.1Rad；The ratio of the height of the radius and blade of cylinder is 1:0.7~1:
0.9, setting in this way enhances the supercharging effect of the exit guide vane, by test, under same operating condition, air-flow
Static pressure of the gentle stream of static pressure after traditional exit guide vane after the exit guide vane is compared, and improves 9%~40%.
Detailed description of the invention
Fig. 1 is a kind of perspective view of exit guide vane of the utility model；
Fig. 2 is a kind of main view of exit guide vane of the utility model；
Fig. 3 is a kind of cross-sectional view of exit guide vane of the utility model；
Fig. 4 is the structural schematic diagram of the blade in the utility model.
Specific embodiment
The utility model is further described below with reference to embodiment, this is the preferred embodiment of the utility model.
As shown in Figs 1-4, a kind of exit guide vane, including cylinder 1 and more blades 2, the blade 2 are uniformly fixedly arranged on described
It further include clamping ring 3 on the external peripheral surface of cylinder 1, the blade 2 is fixedly arranged between the clamping ring 3 and the cylinder 1；
The top of the blade 2 is equipped with multiple fixing lug boss 21, and the fixing lug boss 21 is embedded in the clamping ring 3；The blade 2 is
Arc shaped blade, the radian of the blade 2 are 0.8Rad-1.1Rad；The ratio of the height of the radius and blade 2 of the cylinder 1
Example is 1:0.7~1:0.9.
The blade 2 of the exit guide vane is fixedly arranged between clamping ring 3 and cylinder 1, and the fixation of blade 2 is more firm；The top of blade 2
Equipped with multiple fixing lug boss 21, fixing lug boss 21 is embedded in clamping ring 3, further fixes blade 2.Blade 2 is arc shaped blade, leaf
The radian of piece 2 is 0.8Rad-1.1Rad, and the ratio of the height of the radius and blade 2 of cylinder 1 is 1:0.7~1:0.9, passes through this
The setting of sample enhances the supercharging effect of the exit guide vane, and by test, under same operating condition, air-flow passes through the postposition
Static pressure of the gentle stream of static pressure after traditional exit guide vane after guide vane is compared, and improves 9%~40%.
Referring to Fig. 3, being equipped with hollow part 11 in the cylinder 1 to mitigate the quality of cylinder 1.Hollow part 11 also acts as
Save the effect of material.
Referring to Fig. 1, the middle part of the cylinder 1 is equipped with the first mounting hole 12.First mounting hole 12 is used for exit guide vane
It is mounted on blower.
Fig. 1 and Fig. 2 are please referred to, the clamping ring 3 is annular in shape, is equipped with installation on the edge at 3 both ends of clamping ring
Annulus 31, the mounting circular ring 31 are equipped with multiple second mounting holes 311.Second mounting hole 311 is for pacifying the exit guide vane
On the shell of blower.
Referring to Fig. 2, the quantity of the blade 2 is 11 to prevent blade 2 from vibrating.
The utility model has the following beneficial effects: the blade of the exit guide vane is fixedly arranged between clamping ring and cylinder, blade is solid
It is fixed more firm；The top of blade is equipped with multiple fixing lug boss, and fixing lug boss is embedded in clamping ring, further fixes blade；Blade
For arc shaped blade, the radian of blade is 0.8Rad-1.1Rad；The ratio of the height of the radius and blade of cylinder is 1:0.7~1:
0.9, setting in this way enhances the supercharging effect of the exit guide vane, by test, under same operating condition, air-flow
Static pressure of the gentle stream of static pressure after traditional exit guide vane after the exit guide vane is compared, and improves 9%~40%.
The utility model is not limited to the above embodiment, it is all using structure similar with the utility model and its method come real
All modes of existing the utility model aim, both are within the protection scope of the present invention.
