The adjusting of fan operation operating mode has two kinds of methods: the first changes the performance curve of blower fan itself, is divided into speed change adjusting and movable vane and regulates; It two is to change characteristic curve of pipeline, and outlet throttling adjusting, inlet throttle adjusting etc. are arranged.
Movable vane is regulated the adjusting to fan performance, is to realize through the operating angle that regulating system changes impeller blade (movable vane).When the angle of movable vane changed, its air quantity, blast, power also changed, and made the performance curve displacement of blower fan.If need flow and pressure head to increase, only need to increase the movable vane established angle; Otherwise only need reduce the movable vane established angle.
In the existing technology, the movable vane established angle controlling device of movable vane regulating type axial-flow blower has stop single blade control device, mechanical parking movable vane of mechanical type to concentrate synchronous adjustable device and hydraulic pressure movable vane controlling device etc.Wherein, hydraulic pressure movable vane controlling device is used the most extensive.
There is following shortcoming at least in hydraulic type movable vane adjustable fan of the prior art:
Complex structure, rotary component is many, accuracy of manufacturing is high, blade material require high, operational reliability is relatively poor etc., mainly show as wind motor leaf and regulate difficulty, hydraulic pressure installation leakage of oil etc.
Summary of the invention
The purpose of the utility model provide a kind of simple in structure, regulate the electric-controlled type movable vane adjustable shaft flow fan reliable, that control accuracy is high.
The purpose of the utility model realizes through following technological scheme:
The electric-controlled type movable vane adjustable shaft flow fan of the utility model comprises movable vane and petiole, and said petiole is connected with adjustment disk through adjustable lever, and said adjustment disk is connected with electric-controlled type movable vane controlling device.
Technological scheme by above-mentioned the utility model provides can be found out; The electric-controlled type movable vane adjustable shaft flow fan that the utility model provides; Because adjustment disk is connected with electric-controlled type movable vane controlling device, through the adjusting of automatically controlled realization wind motor leaf, simple in structure, regulate reliable, control accuracy is high.
