流槽截流 的英文怎麼說
中文拼音 [liúcáojiéliú]
流槽截流
英文
chute cut off-
Fluid noise mainly comes from out put pulsation of rate of flow, the main reason of out put pulsation of rate of flow is the instant high pressure return flow that obturation cubage produced when the big round curve pressure transition. the v trough on the port plate can reduce the fluid noise. in this paper, the author based on the acting of dam a river and condensability of liquid and used matlab language as tool to calculate the v trough on the original port plate and drew out the p - t diagrammatic curve and analyzed its shortcoming and improved the design of original v trough and got that the best size of its angle was 12. 3 and its length was 5mm and the cross section was an equilateral triangle
流體噪聲主要來源於輸出流量脈動，造成輸出流量脈動的主要原因是閉死容積在大圓弧段壓力切換時產生的瞬時高壓迴流，在配流盤上開設v型尖槽可降低因高壓迴流而引起的流體噪聲，本文以截流作用和液體的可壓縮性為理論依據，以matlab語言為工具，對原配流盤上的v型尖槽進行了理論計算，繪制出p - t圖線，分析了它的不足，並對原有v型尖槽進行了優化設計，得出了v型尖槽的最佳幾何尺寸：配流盤平面上的v型尖槽的兩邊的夾角為12 . 3 ，槽長5mm ，槽的橫截面為等邊三角形。Drilled holes and screw connections for busbars ; channel section busbars
匯流條用鉆孔和螺紋連接件.槽形截面匯流條In this way, when obturation cubage leave absorb oil cavity it connects the eduction oil cavity with the v trough and with the increasing of the turning angle, the size of the cross section of v trough become bigger and bigger, which make the pressure between the cavity of two blades much higher and higher, and until it completely connects the eduction oil cavity, it reaches the pressure of the eduction, and it can effectively reduces the fluid noise caused by high pressure return flow
這樣，當密閉容積離開吸油窗口之後，通過v型尖槽逐漸與排油窗口連通，隨著轉角的增加， v型尖槽通流截面積逐漸增大，這就使兩葉片間容腔內的壓力逐漸升高，直至完全接通排油窗口時，才升壓達到壓油腔的壓力，這樣可以有效地降低因高壓迴流而引起的流體噪聲。A flap vlave used in pumping station is a kind of hydraulic - operated automatic gate, which is similar to a hinged check vaive. because of their simple structure and reliability, being able to shorten the length of outlet passage and facilitate the starting of pumping system in comparison with siphonic vacuum - distroied cutoff scheme. so it is propitious to be used and save investment but at the same time, flap valves always show some disadvantage
因拍門簡單、可靠，與虹吸真空破壞截流閉鎖方式相比，可以縮短出水管道（流道）長度，並利於泵系統起動，與快速閘門相比，拍門也有諸多優點，閘門門體易關閉不到位或卡住不能活動，因為門槽和?塊較軸孔容易殘留異物，閘門門體克服滑動阻力不僅無機械增益，且阻力和動力不在一直線上，門體易傾斜而自鎖，而拍門的工作可靠性則遠高於快速閘門。Analyses of the monitored seepage data of the sand case dam with clay core of jilihe reservoir show that the impervious effect of the clay core is good, that the blanket in the front of the dam has little impervious effect, and that seepage failure will probably take place because of the weak cutoff groove and the large seepage gradient
摘要對吉利河水庫粘土心?砂殼壩的滲流觀測資料分析表明，該壩粘土心?的防滲效果較好，但壩前鋪蓋沒起到防滲作用，且截滲槽較薄弱，滲透比降較大，可能發生滲透破壞。Tank wagons and tank containers ; shut - off devices with flange connection ; mounting and connecting dimensions, accessories

同步帶的背部用以粘結包覆抗拉元件，應有良好的柔韌性和耐曲撓疲勞性能，不易老化，耐油性好，耐磨損，在帶背的內表面開有適當大小的尖角凹槽，除因工藝要求外，還能改善帶的曲撓疲勞性能，同時在運轉過程中使帶與輪間的截流空氣逸出，以消除部分噪音。分享友人
