Description
Technical field
This patent relates to a kind of adjusting vane axial-flow blower that do not stop.When fan operation, can control by the angle of any adjusting fan blade the variation of airflow pressure.
Background technique
Current axial-flow blower on the market, the fan blade of blower fan is all fixed, and the air quantity of blower fan and blast all can not be adjusted when fan operation.At some, need to adjust the occasion of airflow pressure, normally adopt and control the rotating speed of blower fan or install air-valve adjustment additional on the connecting tube of blower fan.
In some special applications, owing to adjusting rotation speed of fan and air-valve, need the regular hour just can reach technological requirement, therefore on the technique of some products, can produce certain impact, when adopting, do not stop after adjusting vane axial-flow blower, it is very convenient, quick and stable that the adjusting of airflow pressure can become.
Summary of the invention
Each blade angle of the utility model patent can regulate arbitrarily, in the bottom of every blade, be connected with a passive angular wheel, a worm gear speed-reducing motor is housed on the housing of blade, motor adopts stepper motor, turbine on reducer of turbodrill connects with initiative taper generating gear, initiative taper generating gear, centered by the driving sleeve of blower fan, meshes the passive angular wheel on each blade, thereby reaches the object of adjusting vane angle.At center end cap and motor front end cover place, conductive hoop is installed, is used for transmitting the regulated signal of fan blade.
The blade, housing of adjusting vane axial-flow blower of not stopping adopts cast aluminium structure, worm gear adopts tin bronze to process, worm screw adopts steel, and end cap adopts aluminium casting, and conductive hoop parts adopt insulating material, carbon brush, brass to process, angular wheel adopts steel processing, fan blade adopts aluminium casting, for guaranteeing the accurate control of angle of fan leaves, adopts step motor control, for control, require extra high blower fan, can adopt actuating motor to control
Operating principle: adopt worm speed reducer adjusting vane angle, adopt stepper motor to drive, utilize the latching characteristics of stepper motor and worm speed reducer, guaranteed blade stablizing when work.
While needing adjusting vane to change fan performance, by stepper motor input power, to worm screw, worm screw drives worm gear, then drives initiative taper generating gear to rotate by worm gear, finally by initiative taper generating gear, is driven passive angular wheel rotation and is changed blade angle.The control signal of blade angle can be by step-by-step controller or given by computer remote independently.
Do not stop adjusting vane axial-flow blower by housing (1), worm screw (2), center end cap (3) with conductive hoop, conductive hoop wire board (4), main bearing set screw nut (5), main bearing (6), screw connection (7), worm gear (8), initiative taper generating gear (9), driving sleeve (10), blade set screw nut (11), passive angular wheel (12), blade rotary bearing (13), blade bearing is end cap (14) fixedly, blade (15), stepper motor (16), balance adjustment piece (17), fan motor (18), fan motor axle (19) forms.
