Centrifugal blower is by the mechanical energy of input, improves gas pressure and supplies gas side by side the machinery of body, is a kind of driven
Fluid machinery.Centrifugal blower be widely used in the ventilation of factory, mine, tunnel, cooling tower, vehicle, ship and building, dust discharge and
Cooling；The ventilation of boiler and industrial furnace and air inducing；Cooling and ventilation in the apparatus of air conditioning and domestic electric appliance；Wind-tunnel
Inflation and propulsion of wind regime and aircushion vehicle etc..
Centrifugal blower at work, air-flow by wind turbine axially into blade space, then in the driving further aspect of impeller
It is rotated with impeller；On the other hand energy is improved under the action of inertia, impeller is left along radial direction, come by the centrifugal force of generation
Acting, therefore referred to as centrifugal fan.
Centrifugal blower is that work(is delivered to air by approach in this way：--- transmission device --- wind wheel --- is empty for motor
Gas.So the structure that centrifugal blower should possess is：Motor, transmission device, wind wheel, spiral case.Motor is the source of power, is passed
Device is the transmission medium of power, and wind wheel is the basic instrument to air acting, and spiral case is the guide device of air flow.
In the room ventilation application scenario that the demands low noise such as fan coil, multi-connected machine, air curtain is mute, actually using
It is limited to the presence in the multigroup driving motor of centrifugal blower and air draught gap in journey, there is inevitably disconnected wind phenomenon at air outlet.
Wind speed is bigger, the more multibreak wind phenomenon of motor is more apparent.Break wind phenomenon to solve outlet air, usually there are two types of solutions.The first
Scheme be spiral case air outlet front end add wind deflector, by certain angle of inclination by air outlet air-flow retention tiltedly lead it is a part of past
Wind is mended at disconnected wind.Second scheme is that outlet air bellows are added after spiral case air outlet, by air-flow after the secondary diffusion compression of bellows
Blowout, it will usually outlet air dynamic pressure, static pressure be caused to reduce.Both the above scheme all there are one it is inevitable the shortcomings that：Lengthen complete machine
Width dimensions, are limited occasion or economize on and do not apply to from the aspect of material in some volumes.
To solve the problems, such as that conventional spiral case mounting means is single, outlet air is broken, and stratification of wind is more, and existing spy discloses a kind of new installation
The anticentripetal spiral casing scheme of structure and outlet air wind-guiding form.Script is creatively added the wind deflector in outlet air metastomium by the program
It is directly merged into outlet air bellows on spiral case, the oblique pilot wind structure of addition, makes exit flow more directly at spiral case air outlet
Outlet air air-flow that is flat, while having past both ends tiltedly to lead can reduce disconnected stratification of wind and exist to greatest extent.
