The air - flow field in the stripping unit can be adjusted easy by changing the rotation speed of fan which is benefit to reduce the grain losses, it was found during experiment that the cross - flow fan can diffuse some of mog ( material other of grain ) and diffuse it in a certain direction which is useful to satisfy the working condition for driver and lighten working load of the threshing unit of the combine harvester candidate and speciality : peng shengmin ; machinary design and theory supervisor : prof. zhang huiyou
該裝置可以通過控制橫流風機的轉速,使裝置內氣流在有控制的情況下排出裝置外,改善了裝置內流場狀態,提高了裝置喂入口處的負壓,這對減少摘脫裝置的落粒損失,有著重要意義。由於橫流風機的除雜,可以減輕機器的復脫和清選負荷。安裝橫流風機后可以對裝置的出風口處灰塵進行有效導引,改善駕駛員的工作條件。Code for design of structure of cross - flow mechanical ventilation cooling tower
石油化工企業橫流式機械通風冷卻塔結構設計規范Computational fluid dynamics ( cfd ) techniques are used to study and understand fluid behavior in tunnels. by simulating complex specific operational cases, we can educe velocity or flux distribution in tunnel under different ventilation and resistance situation and determine the favorable operational procedures of the erlang mountain tunnel ventilation in a fire case. comparison has been made between a simulation and experiment for some cases in order to prove the cfd model is powerful, so that enables the study of cases for which experimental data is not available
採用本文將隧道內的氣流看成是理想流體的一維恆定流動,通過對二郎山特長公路隧道半橫向通風系統建立隧道內的空氣動力學模型,利用計算機進行數值分析與計算,得出發生火災時,不同通風阻力條件下隧道中的風速分佈及流量分佈,並通過實驗室隧道模型實驗進行驗證與修正,依據研究結果給出了二郎山半橫向通風隧道的火災控制方案,從而解決了二郎山公路隧道通風對火災的控制問題,同時為半橫向通風公路隧道的火災通風提供科學的方法。Through the experimental analysis of the single factor, the influence of the rotation speed of the two kinds cross - flow fan and the forward speed was find on grain losses of the unit, finally the optimum combination of the forward speed and the rotation speed was got
通過單因素的實驗分析,找出在橫流風機不同風機轉速,不同的行車速度下摘脫裝置落粒損失的變化規律,並確定了最佳的裝置參數組合。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。The work here has a lot of application and stringency. for the first time, the various ventilating methods and effects to control the smoke in a fire emergency of the erlang mountain tunnel semi - transient ventilation road tunnel are presented. with the hypothesis of one - dimensional steady ideal fluid, the experimental and numerical studies are presented
