kkk fan guide vane issue
Thread Content
I would like to ask: The KKK fan adjusts the air volume by adjusting the opening angle of the guide vanes. What are guide vanes? Could you please explain that? And how do they function? Is it the same as the blades of a fan? But how does it function (by contracting inward or expanding outward) to regulate the air volume?
A setting outside the inlet, adjustable from 0 to 90 degrees, to control the inlet
Thank you, I know that. I want to figure out what the mechanism is – is it the direction, or is it made up of many blades just like those on a fan?
It is composed of many blades, arranged in a manner similar to that of a fan; the gaps between the blades are very small, not as large as those between the blades of a fan. When fully closed, each blade is parallel to the connecting flange, blocking the cross-section of the pipe. When fully open, each blade rotates 9° and becomes perpendicular to the connecting flange (in other words, the blades stand upright), and thus they no longer block the cross-section of the pipe.
