中文拼音 [jìngxiàngqìxì]
徑向氣隙
英文
radial air gap-
Ball bearings, conrad type, for electrical machines ; tolerances and radial clearance
電氣機械用的連桿式球軸承.公差和徑向間隙It was found that the ultra - fine powder can flow smoothly in a spouted bed with a draft tube under some sorts of design parameter and operating condition, thus a new effective method to improve fluidization quality of the ultra - fine powders is obtained ; at higher supplied gas velocity, an increase in the solid circulation rate is observed ; the extent of the distance between the nozzle and the draft tube inlet result in the promotion of the solid circulation rate ; the solid circulation rate increase with increasing the draft tube diameter or the bed mass ; the gas bypassing is nearly zero in the present work ; and the solid flow in the annulus is observed as a moving bed
結果表明：在一定的床層結構和操作條件下，超細粉可以在導向管噴動床中實現平穩流化，從而為改善超細粉的流化質量提供了一種有效的新方法；固體循環速率與噴動氣流量、導向管直徑、導向管底部與噴嘴出口間距以及床層裝填量成正比；氣體則基本上不存在「旁路」現象；環隙區中的顆粒流動表現為一移動床特徵。A new bearingless induction motor system with five degrees of freedom is developed including a bearingless induction motor and a permanent magnet biased axial - radial magnetic bearing. the control strategy of bearingless induction motor based on air - gap flux orientation is introduced, and the decentralization pid control is used to maintain equal air in the five degrees of freedom. the digital controller guarantees rotor suspension steadily, and the speed of rotor reaches 3000 rpm
闡述了無軸承異步電機的氣隙磁場定向控制策略，採用該非線性控制方法能使無軸承異步電機解耦成轉矩子系統和磁懸浮徑向力子系統，從而可以採用經典pid對這兩個獨立的子系統進行控制，首次實現了系統在0 3000rpm轉速范圍內的穩定懸浮。Fluidized behaviors of ultra - fine powder caco3 of mean diameter 5 um in a spouted bed with a draft tube were investigated, studying the effects of geometry and operating parameters on the two - phase fluidized characters such as the initial spouted behavior, the solid circulation rate, the gas flow distribution in the spout and the annulus, and the solid flow in the annulus
本研究以平均粒徑為5 m的caco _ 3超細粉為物料，對超細粉在導向管噴動床中的流化行為進行了系統的實驗研究，考察了床層結構和操作條件對起始噴動行為、固體循環速率、氣體在床層雙區中的分配以及固體顆粒在環隙區中的流動等氣固兩相流動特徵的影響。分享友人
