Blower fan is that the custom of gas compression and gas conveying machinery is called for short by China, usually said blower fan bag
Include: ventilation blower, aerator, wind-driven generator.Gas compression and gas conveying machinery are the machine rotated
Tool can be converted to gas pressure energy and kinetic energy, and the machinery transferred out by gas.
The main structural components of blower fan is impeller, casing, air inlet, support, motor, belt pulley, connection
Axial organ, deafener, driving member (bearing) etc..
Unpowered ventilation machine is the air thermal convection current utilizing natural wind and indoor and outdoor temperature difference to cause, and promotes
Turbine rotates thus utilizes 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.Empty according to country
Adjust equipment quality Supervision Test Center aerator supervision for many years to show that a lot of blower fan all exists under declared working condition to ask
Topic, it is therefore desirable to require to produce and manufacture blower fan in strict accordance with product standard.
When blower fan is just started working, the vibration of bearing portion is the least, but is as the lengthening of the duration of runs, wind
What in machine, dust can be uneven is attached on impeller, gradually destroys the dynamic balancing of blower fan, make bear vibration by
Gradually strengthening, (maximum represented with amplitude permits to reach, once vibration, the maximum 11mm/s that blower fan allows
Permitted value as follows), blower fan must shut down repairing (removing dust accumulation, dynamic balancing of reforming).And blower fan stall
Repair and typically all operated by professional person, fairly cumbersome, it is difficult to operation, it would be highly desirable to improve.
Summary of the invention
Present invention aims to defect and the deficiency of prior art, it is provided that a kind of simple in construction, if
Count air-foil fan reasonable, easy to use, facilitate repair and maintenance, it is not necessary to professional person can realize wind

Being movably arranged on slide rail, slide rail is arranged in blower housing；It also comprises rocking bar, gear, a tune
Joint screw rod, support, bearing, No. two bearings, No. two gears, screwed holes；Rocking bar passes through No. two axles
Holding the lower limb being located in blower housing, the left end of rocking bar connects a gear, a gear and No. two
Gear engages, and No. two gears are fixed on the right-hand member of adjusting screw rod, the left end of adjusting screw rod and the spiral shell on base
Pit connects；Described adjusting screw rod is located in support by a bearing, and support is fixed on outside blower fan
In shell.
The top of described base is provided with the fixing connecting hole being connected with motor.
Air intake port in described motor housing is provided with drainage screen, for the filtration to wind regime.
Described base is movably arranged on slide rail by roller, is moved easily.
The operation principle of the present invention: when needs carry out dust disposal to flabellum, can be directly by rotating
Rocking handle, rocking handle passes through a gear and the engagement of No. two gears, drives adjusting screw rod to rotate, adjusting screw rod
Promote base to be moved to the left while rotation, move and carry out dust disposal to air outlet, be particularly suited for
The process of large fan.
After using said structure, present invention have the beneficial effect that a kind of air-foil fan of the present invention, side
Just repair and maintenance, it is not necessary to professional person can realize blower fan is cleared up dust, and practicality is higher, the present invention
There is simple in construction, arrange rationally, the advantages such as cost of manufacture is low.
