Description
Technical field
The utility model is related to blower field, specially a kind of three source stream high pressure blower rotors for centrifugal blower.
Background technique
Existing centrifugal high pressure fan is substantially that volume is big, and power of motor is big, it is difficult to reach ideal wind pressure, and there are huge
Big noise.
Summary of the invention
Purpose of utility model: the technical solution of the utility model is intended to provide a kind of three source stream high pressure blower rotors, compares existing
Technology, volume is smaller, more efficient, and tries to reduce the noise of equipment.
Technical solution:
A kind of three source stream high pressure blower rotors, it is characterised in that: fan rotor main body is circular cone drum type fairing；
Strong wind fan leaf is provided in the fan rotor main body；Rotary flat of major fan blade relative to rotor subject
There is inclination angle in face and is cambered surface；
The strong wind fan leaf outer edge is provided with down the blade that goes for a drive:
It further include a collection solar or lunar halo outside fan rotor main body；The blade corresponding position that goes for a drive under on the collection solar or lunar halo is provided with
On go for a drive blade；It goes for a drive on described and is covered with envelope pressing ring on blade；
The collection solar or lunar halo and envelope pressing ring are " bamboo hat shape " taper ring of center opening, and the two taper is different；The upper pocket
Air blade setting is between collection solar or lunar halo and envelope pressing ring；
The blade that goes for a drive on adjacent two is arranged in " people " font；
Lower fan blade is provided with below the fan rotor main body；The lower fan blade section be it is trapezoidal, in rotor
It is in vortex-like arrangement in main body.
The three source streams high pressure blower rotor, it is characterised in that: the lower fan blade quantity is 12 ~ 30.
The three source streams high pressure blower rotor, it is characterised in that: the lower fan blade straight down, in the longitudinal direction
In bowing, it is that arc is round, has inclination angle relative to rotor plane.
Advantage and effect:
The utility model structure novel, components utilising fluid mechanics principle use a main body triple blade diffusion structures,
Increase intake, pressure increases.Overall volume, the weight of blower are reduced simultaneously；It is more suitable high revolving speed.In Same Efficieney
In the case where, generated wind pressure and flow increase, and reach energy-saving and environment-friendly purpose, reduce noise pollution.
Detailed description of the invention:
Fig. 1 is the utility model top view；
Fig. 2 is the utility model side view；
Fig. 3 is the utility model sectional view；
Fig. 4 is lower fan blade schematic diagram；
Fig. 5 is the perspective view on lower fan blade direction；
It is marked in figure: 1 rotor subject；2 strong wind fan leafs；Go for a drive blade under 3；4 collection solar or lunar halo；Go for a drive blade on 5；6 envelope pressures
Circle；7 lower fan blade.
Specific embodiment:
A kind of three source stream high pressure blower rotors, fan rotor main body 1 are circular cone drum type fairing；
Strong wind fan leaf 2 is provided in the fan rotor main body 1；Rotation of major fan blade 2 relative to rotor subject 1
Turning plane has inclination angle and is cambered surface；
2 outer edge of strong wind fan leaf is provided with down the blade 3 that goes for a drive:
It further include a collection solar or lunar halo 4 outside fan rotor main body 1；3 corresponding position of blade that goes for a drive under on the collection solar or lunar halo 4 is set
It is equipped with the blade 5 that goes for a drive；It goes for a drive on described and is covered with envelope pressing ring 6 on blade 5；
The collection solar or lunar halo 4 and envelope pressing ring 6 are " bamboo hat shape " taper ring of center opening, and the two taper is different；On described
The blade 5 that goes for a drive setting is between collection solar or lunar halo 4 and envelope pressing ring 6；
The blade 5 that goes for a drive on adjacent two is arranged in " people " font；
Lower fan blade 7 is provided with below the fan rotor main body 1；7 section of lower fan blade be it is trapezoidal, turn
It is in vortex-like arrangement in sub- main body 1.
The lower fan blade quantity is 12 ~ 30.
The lower fan blade 7 is in bowing straight down in the longitudinal direction, is that arc is round, flat relative to rotor
There is inclination angle in face.
There are certain intervals for the utility model scheme, rotor and Blower Housing, as long as Blower Housing runner is smooth, smooth, pressure
Just will increase, no matter rectangular or circular flow channel, flow channel shape be nest shape from small to large.
The utility model structure novel, components utilising fluid mechanics principle use a main body triple blade diffusion structures,
Increase intake, pressure increases.Overall volume, the weight of blower are reduced simultaneously；It is more suitable high revolving speed.In Same Efficieney
In the case where, generated wind pressure and flow increase, and reach energy-saving and environment-friendly purpose, reduce noise pollution.
