Summary of the invention
It is an object of the invention to provide a kind of low-resistance Centrafugal roof fan, this blower fan can reduce the resistance of inlet and outlet runner.
For reaching above-mentioned purpose, the technical solution adopted in the present invention is:
A kind of low-resistance Centrafugal roof fan, including the current collector being positioned at above base plate, blast cap, impeller, motor, motor peace
Fill plate, motor urceolus, the outer barrel cover of motor and be positioned at the BAIYE below base plate；Motor is positioned at motor urceolus, by motor
The impeller driven is positioned at blast cap；Current collector is located between base plate and blast cap；Also include air outlet stator blade group and BAIYE
Framework；Louver frame is arranged on base plate bottom, and BAIYE is arranged on louver frame bottom；Air outlet stator blade group is arranged on blast cap
In, and it is peripheral to be positioned at impeller, air outlet stator blade group is mainly made up of straight tube, stator blade and up big and down small cone cylinder, and straight tube is connected to
The lower end of cone cylinder, stator blade is connected to the upper surface of cone cylinder.
As the further setting of such scheme, it is integral type structure (i.e. afflux between described current collector and base plate
Device is by a part of base plate punch forming).
Described motor and motor urceolus are installed on motor mounting plate, and motor mounting plate is arranged on wind by support bar
On machine base, blast cap upper end is supported by blast cap and is connected with motor mounting plate, and support bar and base plate are passed through in blast cap lower end
It is connected.
One low-resistance Centrafugal roof fan of the present invention, increases air outlet stator blade group, air outlet stator blade group at air outlet
Stator blade be designed to certain radian according to the flow angle of impeller air outlet, be connected with the cone cylinder of air outlet stator blade group, make blower fan
Air outlet loss reduces.Meanwhile, louver frame adds the distance between BAIYE and current collector, and air is through BAIYE wind direction meeting
There is the change of certain angle, increase the distance between BAIYE and current collector, air can be corrected to a certain extent and entering collection
Angle during stream device, thus reduce the loss of air inlet.
In a word, the present invention a kind of low-resistance Centrafugal roof fan can reduce the resistance of inlet and outlet runner, has air inlet/outlet
The feature that mouth loss is little.
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
As it is shown in figure 1, one low-resistance Centrafugal roof fan of the present invention, including the current collector 1 being positioned at above base plate 13, wind
The outer barrel cover 10 of cap 2, impeller 6, motor 8, motor mounting plate 7, motor urceolus 9, motor and be positioned at hundred below base plate 13
Leaf 12；Motor 8 is positioned at motor urceolus 9, motor 8 impeller 6 driven is positioned at blast cap 2；Current collector 1 is located at base plate
Between 13 and blast cap 2.The improvement of the present invention is: also include air outlet stator blade group 4 and louver frame 11；Louver frame 11 is pacified
Being contained in base plate 13 bottom, BAIYE 12 is arranged on louver frame 11 bottom；Air outlet stator blade group 4 is arranged in blast cap 2, and position
Peripheral in impeller 6, air outlet stator blade group 4 is mainly made up of straight tube 41, stator blade 43 and up big and down small cone cylinder 42, and straight tube 41 connects
In the lower end of cone cylinder 42, stator blade 43 is connected to the upper surface of cone cylinder 42.
For optimizing structure, it is integral type structure between current collector 1 and the base plate 13 in the present invention.
For optimizing structure further, in the present invention, motor 8 and motor urceolus 9 are installed on motor mounting plate 7, motor
Installing plate 7 is arranged on base plate 13 by support bar 3, and blast cap 2 upper end supports 5 by blast cap and is connected with motor mounting plate 7
Connecing, blast cap 2 lower end is connected with base plate 13 by support bar 3.
In the present embodiment, to be rigidly connected between the miscellaneous part such as base plate 13 and impeller 6, can avoid the occurrence of because of earthquake
And the grazing between the rotatable parts caused and stationary parts.Specifically include: motor 8 and motor urceolus 9 are all installed by bolt
On motor mounting plate 7, the outer barrel cover 10 of motor is bolted on motor urceolus 9, and motor mounting plate 7 is by support bar 3
Being arranged on base plate 13 with bolt, blast cap 2 upper end supports 5 by blast cap and is bolted on motor mounting plate 7, blast cap
2 lower ends are by support bar 3 and are bolted on base plate 13, and air outlet stator blade group 4 is bolted in blast cap 2.
Louver frame 11 is welded on base plate 13 bottom, and BAIYE 12 is arranged in louver frame 11 by bolt.
In the present embodiment, current collector 1 uses presses ventilation blower industry standard matched in clearance between streamline curve, and impeller 6,
Make the loss of blower fan air intake minimize, improve fan efficiency.
Impeller 6 have employed strong palintrope, Wind Volume, the design of low noise objective optimization, and characteristic curve of fan is smooth.
Stator blade 43 is welded on after making certain radian according to the flow angle at impeller air outlet in cone cylinder 42, and cone cylinder 42 is welded
It is connected in straight tube 41.
In the present invention, BAIYE 12 is connected with base plate 13 by louver frame 11, add BAIYE 12 and current collector 1 it
Between distance, to a certain extent correct air change of the wind when through BAIYE 12, reduce centrifugal fan at air intake
The resistance of mouth runner；Air passes through the cone cylinder 42 of air outlet stator blade group 4 before discharging at air outlet time, make air-out direction by air
Stream angle turns to and changes little airflow angle into and turn to air-out, adds the effect of air outlet stator blade 43, reduces centrifugal fan in air-out
The resistance of mouth runner.
When the present invention uses, switching on power, motor 8 operates, and is operated by motor rotation axis impeller 6, makes air warp
Cross BAIYE 12, louver frame 11, then suck from current collector 1 one end, discharge at air outlet.Air passes through air-out at air outlet
During the cone cylinder 42 of mouthful stator blade group 4, make air-out direction be turned to by big flow angle and change little airflow angle into and turn to air-out, add air outlet
The effect of stator blade 43, reduces the centrifugal fan resistance at inlet and outlet runner.
