Description
Technical field
The utility model relates to a kind of centrifugal blower, in particular to a kind of centrifugal blower with air inlet guide blades.
Background technique
In the important equipment of numerous industry, centrifugal blower is had a wide range of applications, but due to the gas in impeller assembly
Stream interaction, consumes a large amount of non-renewable energy.In general, in practical application in industry, when blower fan system is in non-design work
When working under condition, maximal efficiency of the Real time Efficiency lower than design.Due to complicated air flow condition in the blower of rotation, such as flow
Dynamic separation and Vortex Shedding, air-flow are often unstable.Chinese patent 201721440246.6,201510670790.9 from
The blade of the impeller of heart blower is perpendicular to impeller front disc and impeller hub disk, this causes blade passage to the impact strength of spiral case
It is larger, to generate biggish noise at work, and there is biggish resistance, causes the ventilation quantity of centrifugal blower lower.
Utility model content
The purpose of this utility model is to provide a kind of overall efficiency that can be improved centrifugal blower, stagnation pressure and energy benefits
With the centrifugal blower with air inlet guide blades of efficiency, to solve the problems mentioned in the above background technology.
To achieve the above object, the utility model provides the following technical solutions: it is a kind of with air inlet guide blades from
Heart blower, including spiral case, impeller assembly, air inlet guide blades, collector and motor, before the impeller assembly includes impeller
Disk, impeller hub disk and the blade positioned at the impeller front disc and the impeller hub disk, the air inlet guide blades are located at institute
It states between collector and the impeller assembly air inlet.
Preferably, the air inlet guide blades are made of blade fixing end and the blade oscillating wing, the blade oscillating wing
It can be along rotary shaft radial direction left and right deviation blade fixing end.
Preferably, the blade oscillating wing can be radially offset from blade fixing end-α or+α angle, and the range of α is 0 ~ 20,
It is -20 ° ~+20 ° that i.e. the blade oscillating wing, which can deviate the angle of blade fixing end,.
Preferably, there is the air inlet guide blades rotary shaft along the centrifugal blower to be axially displaced from angle.
Preferably, the angle that is axially displaced from is 0 ° ~ 60 °.
Compared with prior art, the utility model has the beneficial effects that
1, there is blade fixing end and blade oscillating end by the blade in setting impeller assembly, blade oscillating end can be with
It is set according to different centrifugal blower requirements, and then the air-flow of blade edge is avoided to spring up bring resistance；
2, air inlet guide blades are arranged by the air inlet in centrifugal blower, guide vane angle is optimized, is avoided
What the friction loss on air-flow and air inlet guide blades surface and the chance of a loss at air inlet guide blades edge will lead to
The pressure loss can make centrifugal blower suction position obtain high pressure.
