The grain losses were measured and compared when adopting the two different cross - flow fan, and the reason of the grain loss was analysied on the unit with two kinds of cross - flow fan, it ' s found that the cross - flow fan with bent vane is superior to the vertical vane. the pneumatic performance of the model cross - flow fan used in this dissertation was pre - searched at 1500 rpm by professor wang in this dissertation
試驗所用的曲板式橫流風機為前人研製的模型風機,本文通過該風機在1150r / min的轉速下的特性曲線,運用相似理論推導出其在550r / min 、 450r / min 、 350r / min的轉速時該風機的特性曲線。
