Description
Technical field
This utility model relates to a kind of blower fan.
Background technology
Blower fan is dependent on the mechanical energy of input, improves gas pressure and supplies gas side by side the machinery of body, and it is a kind of driven stream
Body machinery.Blower fan is that the custom of gas compression and gas conveying machinery is called for short by China, and usually said blower fan includes: ventilate
Machine, aerator, wind-driven generator.Gas compression and gas conveying machinery be rotate mechanical energy be converted to gas pressure can and
Kinetic energy, and the machinery that gas is transferred out.
The main structural components of blower fan be impeller, casing, air inlet, support, motor, belt pulley, shaft coupling, deafener,
Driving member etc..Unpowered ventilation machine is the air thermal convection current utilizing natural wind and indoor and outdoor temperature difference to cause, and promotes turbine rotation
Turn thus utilize centrifugal force and underbalance effect to be discharged by indoor stale hot-air.
Blower fan is related to the transmission & distribution energy consumption of system, is the most crucial part of building energy conservation.According to country's air-conditioning equipment matter
Amount Supervision Test Center aerator supervision for many years shows that a lot of blower fan is problematic in that under declared working condition, it is therefore desirable in strict accordance with
Product standard requires to produce and manufacture blower fan.When blower fan is just started working, the vibration of bearing portion is the least, but when being as operating
Between lengthening, what in blower fan, dust can be uneven is attached on impeller, gradually destroys the dynamic balancing of blower fan, makes bear vibration gradually
Strengthening, reach, once vibration, the maximum 11mm/s that blower fan allows, blower fan must shut down repairing.
Current existing blower fan structure is simple, and structural strength is the highest, and operation stability is poor, installs inconvenience.
Utility model content
It is high that the technical problems to be solved in the utility model is to provide a kind of structural strength, reliable and stable, easy installation and reliable,
The blower fan that ventilation effect is good.
For solving the problems referred to above, this utility model adopts the following technical scheme that a kind of blower fan, including base, casing, motor
And frame, described casing and motor be located on base, and described casing and motor are fixing with base respectively to be connected, and described erecting exists
Casing side, described frame and welding box body, described frame side is provided with belt pulley, and described frame opposite side is provided with horizontal stroke
Bar, described cross bar and welding machine frame, described belt pulley is provided with belt, described belt pulley is by belt with motor-driven even
Connecing, described belt pulley one end is provided with rotating shaft, and described rotating shaft is provided with the first impeller and the second impeller, and described casing is arranged
There is ventilator cowling.
As preferably, described base is channel steel base, keeps structural strength high, lightweight.
As preferably, described casing is aluminium alloy box, keeps good heat dissipation effect.
As preferably, described first impeller and the second impeller are fixed and are connected, and keep compact conformation.
As preferably, described ventilator cowling is that inclination angle is arranged, and keeps easy installation and reliable.
The beneficial effects of the utility model are: the base of setting and frame keep structural strength high, and cross bar can elevator
The stability of frame；The first impeller arranged and the second impeller keep ventilation effect good；There is belt pulley the frame side arranged, it is possible to
Keep easy installation and reliable；The belt arranged keeps transmission effective, and noise is low.
Accompanying drawing explanation
Fig. 1 is the structure chart of a kind of blower fan of this utility model.
Detailed description of the invention
As it is shown in figure 1, a kind of blower fan, including base 1, casing 2, motor 3 and frame 4, described casing 2 and motor 3 are located at
On base 1, described casing 2 and motor 3 are fixing with base 1 respectively to be connected, and described frame 4 is located at casing 2 side, described frame 4
Welding with casing 2, described frame 4 side is provided with belt pulley 5, and described frame 4 opposite side is provided with cross bar 6, described cross bar 6 with
Frame 4 is welded, and described belt pulley 5 is provided with belt 7, and described belt pulley 5 is in transmission connection with motor 3 by belt 7, described skin
Belt wheel 5 one end is provided with rotating shaft 8, described rotating shaft 8 is provided with the first impeller 9 and the second impeller 10, described casing 2 is provided with
Ventilator cowling 11.
Described base 1 is channel steel base.
Described casing 2 is aluminium alloy box.
Described first impeller 9 is fixing with the second impeller 10 to be connected.
Described ventilator cowling 11 is arranged in inclination angle.
The beneficial effects of the utility model are: the base of setting and frame keep structural strength high, and cross bar can elevator
The stability of frame；The first impeller arranged and the second impeller keep ventilation effect good；There is belt pulley the frame side arranged, it is possible to
Keep easy installation and reliable；The belt arranged keeps transmission effective, and noise is low.
The above, detailed description of the invention the most of the present utility model, but protection domain of the present utility model does not limit to
In this, any change expected without creative work or replacement, all should contain within protection domain of the present utility model.
