中文拼音 [jǐyājīlìyònglǜ]
擠壓機利用率
英文
availability rate-
The operating rate of extrusion machine in china is only 35 % or so, which falls long distance behind of the developed countries " level, and is less 30 % than the world average operating rate. over the 90 % of china ' s aluminum section for building belong to the low level product, the rate of high additional value product is low, and is lack of the famous brand
而中國擠壓機的開工率僅為35 %左右，遠遠落後于發達國家水平，比世界平均利用率低30個百分點。我國建築鋁型材90 %以上在國際市場上屬低檔產品，高附加值產品比重低，缺乏著名品牌。缺乏國際競爭力。The disposal of the valves and intake manifold structure not only affect fresh air charge but airflow in the cylinder, which immediately affect combustion efficiency and the performance of dynamic, economic and emission. the structure of the air distributing institution has influence on charging efficiency and the noise of engine. the combustion chamber affects compression scale which has great influence on dynamical performance ; f / v which affects the exhaust of hc ; squash area and clearance which have great influence on the intensity of squash
氣缸蓋的氣門排列方式與氣道結構形式影響進氣充量和氣流在氣缸內的運動，從而影響了燃燒效率，對整機的動力性、經濟性以及排放都有直接的影響；配氣機構的形式影響充氣系數和整機噪聲等；缸蓋燃燒室決定了影響整機動力性能的壓縮比，影響hc排放的f / v和對擠流起決定性作用的擠氣面積以及擠氣間隙，所以燃燒室對整機動力性、經濟性、排放等都有重要的影響；氣缸蓋是整機熱負荷與熱應力最大的部件之一，熱負荷過高將不利於發動機壽命以及可靠性的提高。Based on the productive experiment on heihe dam site, during april to august 2002, site experiment was made on gongboxia hpp dam site, bjy - 40 extrusion curb placing machine was determined to be applied into gongboxia project, the batch ratio is : cement 80kg / m3, sand 651kg / m3, small stone 1449kg / m3, and sand ratio 31 %, w / c ratio 1. 31, admixture 3 %
在生產性試驗的基礎上， 2002年4 8月，在公伯峽面板壩現場進行了擠壓邊墻施工各個環節的試驗，通過試驗，確定公伯峽面板壩使用陜工局西安理工大學工程項士學位論文水利機械廠研製的bjy 40型混凝土邊墻擠壓機進行固坡施工，其混凝土配合比為：水泥80kgb 』 ，砂651kgb3 ，小石1449kgb 』 ，砂率31 ，水灰比1Crowd out unit using screw that the big proportion of length and diameter, the effictiveness of plasticizing is very good. the head of mould using advanced electromotive system and hydraulic system, the degree of automatization is high, acting facillitately and the high of product efficiency. the head of mould using heating method inside, adjusting easily, the thickness of sheet is very precise, and the availability of heating is high, and saving the electricity
