Description
Technical field
This utility model relates to blower fan cooling device field, particularly to a kind of air-cooled dress for blower motor
Put.
Background technology
At present, the existing type of cooling of motor of thermal power generation unit pressure fan and primary air fan, mainly adopt
Motor is cooled down with fan air-supply.Cooling fan structure is complicated, and parts are more, with pressure fan and once
When blower fan works long hours, due to component wear, it is susceptible to fault, and cooling of can not effectively blowing
Motor；Further, the operating of fan needs driven by power, which increases power consumption and the unit coal of power plant
Consumption.
Summary of the invention
In order to overcome drawbacks described above, the purpose of this utility model is to provide a kind of without driven by power, structure
Simply, it is simple to the energy-conservation air cooling equipment for blower motor safeguarded is installed.
In order to achieve the above object, this utility model is achieved by the following technical solutions.
A kind of air cooling equipment for blower motor, including blower fan, air main, blower motor and motor cover,
The tail end of motor cover is provided with air inlet, is provided with air filter screen in described air inlet, and, described electricity
It is provided with a vent on the front end face of hood, the air main of described blower fan inlet side is provided with bypass wind
Pipe, the free end of described bypass airduct is connected with described vent.
Further, one end port that described bypass airduct is connected with air main is air outlet, described air outlet
Axis be 0 °～90 ° with the angular range of wind direction in the corresponding air main being connected, adjust this angle, can
So that in bypass airduct distinguished and admirable enter air main will not be upset in air main distinguished and admirable, the most favourable
In bypass airduct from outside air draught.
Feature of the present utility model and further improvement is that:
It is provided with volume control damper, in order to control to bypass the circulation air quantity of airduct on described bypass airduct.
Also residing in and offer multiple airing hole in the rear sidewall of described motor cover, these airing holes are permissible
Rotor in the incoming air area of expanded motor cover tail end, more effectively cooling motor cover.
The technical solution of the utility model is passed through to arrange bypass blast pipe on the air main of blower fan inlet side, by
Wind speed in air main is high, and air pressure is less than external atmosphere pressure, after opening bypass blast pipe, bypass into
Airduct is from extraneous air draught, owing to bypass blast pipe air inlet communicates with motor cover, thus in motor cover
Rotor periphery forms cooling airflow, in this way to blower motor cooling；This chiller,
Utilize air main and extraneous pressure reduction convection current, it is not necessary to driven by power, it is not necessary to the frame for movements such as fan, arrange
Convenient, simple in construction, it is simple to safeguard, energy-conservation reliably.
Accompanying drawing explanation
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is that embodiment device arranges schematic diagram；
In figure: 1, air inlet；2, motor cover；3, vent；4, bypass airduct；5, Boiler pressure control
Valve；6, air outlet；7, air main；8, blower fan；9, blower motor；10, airing hole.
Detailed description of the invention
With reference to Fig. 1, this utility model includes blower fan 8, air main 7, blower motor 9 and motor cover 2, electricity
The tail end of hood 2 is provided with air inlet 1, is provided with air filter screen in air inlet 1, and, described motor
Offer a vent 3 on the front end face of cover 2, the air main 7 of described blower fan 8 inlet side is provided with side
Transportation work style pipe 4, bypass airduct 4 comprises vent hose and air outlet 6, and air outlet 6 is a short tube, air outlet
One end of 6 is welded on the sidewall of air main 7, and the other end is connected by pipe collar with vent hose, ventilates soft
The free end of pipe is connected by pipe collar with vent 3；
The axis of air outlet 6 is 60 ° with the wind direction angle of coupled air main 7, and this angle can make
Must bypass in airduct 4 distinguished and admirable enter air main 7 will not be upset in air main 7 distinguished and admirable, also have simultaneously
It is beneficial to bypass airduct 4 from outside air draught；
Further, bypass airduct 4 is provided with volume control damper 5, in order to control to bypass the stream of airduct 4
Ventilation.
Further, the rear sidewall of described motor cover 2 offers multiple airing hole 10, and is ventilating
Aperture 10 corresponding position is provided with air filter screen, and these airing holes 10 can be with expanded motor cover 2 tail
Rotor in the incoming air area of end, more effectively cooling motor cover 2.
Obviously, those skilled in the art this utility model can be carried out various change and deformation without deviating from
Spirit and scope of the present utility model.So, if these amendments of the present utility model and deformation belong to this
Utility model right require and equivalent technologies within the scope of, then this utility model also comprise these change and
Including modification.
