Calculation of unsteady flow for interaction between rotating impeller and vaned diffuser 旋轉(zhuǎn)葉輪和葉片擴壓器耦合的非定常流動計算
Ramjet has been widely used in all kinds of supersonic and high - supersonic aircraft . it has caught more and more attention recently because there is no need for rotating impeller machine 而沖壓發(fā)動機不需轉(zhuǎn)動的葉輪機械,結(jié)構(gòu)簡單,高速性能優(yōu)良,被廣泛用于各類超音速和高超音速飛行器,愈來愈受到人們的關(guān)注。
The filter rate of the rotating impeller press filter and its effective factors in the dye wastewater treatment after flocculation were studied , the dynamic filtration was compared with the terminal filtration , and a comparative research was made of the efficiency in the dye wastewater treatment of the ceramic film and the organic film 考察了以陶瓷膜為過濾介質(zhì)的旋葉壓濾機對絮凝后的廢水進行處理的過濾速率及其影響因素,進行了動態(tài)過濾與終端過濾的比較,以及陶瓷膜與有機膜在廢水處理效果上的對比研究。
The stuffs from the nupper of the machine , falling into the high - speed rotating impeller , strike with other stuffs which more around the impeller because of high - speed centrifugal force . after they strike matually , whirling fluid is produced between the impeller andoutercovering . through repeatedly striking and rubbing , the stuffs are crushed into pieces and straightly come out of the lower . the operating process forms into closed circuit , circulate repeatedly and then attains the fineness of the product 制砂機機制砂生產(chǎn)線打砂機砂石料破碎生產(chǎn)線建筑砂生產(chǎn)線制沙機打沙機河南重型機器廠是生產(chǎn)制砂機系列設(shè)備的專業(yè)廠家, pcl直通沖擊式破碎機制砂機用途廣泛,其性能已達到國際領(lǐng)先水。該沖擊破制砂機是目前最行之有效,實用可靠的碎石機器。
