Zusammenfassung: | PURPOSE:To secure maximum efficiency, by installing a variable pitch type inlet guide vane in the front of a variable pitch type adjustable blade. CONSTITUTION:In case of an air pressure-airflow controller for an axial fan, an adjustable blade 1 is pivotally supported on a rotor 2 and simultaneously disposed inside a fluid passage 3. In the front (the upstream side) of the adjustable blade 1 inside the fluid passage 3, there is provided with an inlet guide vane rotatably. So, when each pitch angle of the adjustable blade of the axial fan and the inlet guide vane is varied at will, operation at a maximum efficient range along an operating line is performable. |
