Description

초대형 원심 팬(fan)Extra Large Centrifugal Fan

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 종래의 2중폭, 2중 도입구 원심팬의 수직부분의 부분단면도.1 is a partial cross-sectional view of a vertical portion of a conventional double width, double inlet centrifugal fan.

제2도는 본 발명에 따른 원심팬 일부분의 부분단면 측면도.2 is a partial cross-sectional side view of a portion of a centrifugal fan according to the present invention.

제3도는 휘일, 스터브촉, 토오크튜브의 다른 취부 설비를 나타내는 단면도.3 is a cross-sectional view showing other mounting equipment for wheels, stubs, and torque tubes.

Claims (5)
