泵送損失 的英文怎麼說
中文拼音 [bèngsòngsǔnshī]
泵送損失
英文
pumping loss-
Then, the change of the pressure of the concrete in the pipage is studied. lastly, the pressure losing and the error of the routine measure are discussed. chapter three discusses the fussy self - study issues based on the concrete technology the first section expounds the basic fuzzy self - study theory
首先介紹泵送混凝土的流動特徵，接著研究泵送混凝土在輸送管中泵送壓力的變化，並分析影響泵送壓力損失的因素，從而討論常規計量方法的缺陷第三章主要是針對前章理論模型應用模糊自學習技術。Firstly, working theory and structure of concrete pump are lucubrated. and the flowing state of the concrete in duct is analyzed by virtue of the rheology theory. secondly, the flowing model of concrete in duct is established, with that, the pressure loss of concrete flowing in duct is analyzed, too
論文首先對混凝土泵的工作原理和結構進行了綜合分析；基於流變學原理，深入分析了泵送混凝土在輸送管中的流動狀態，建立了混凝土在管道中的流動模型，分析了混凝土在管道中流動的壓力損失；基於運動學和動力學基本原理，對混凝土s管閥的運動學和動力學進行了分析。Not only does slump loss influence the effect, it constrains the transportation distance and pumping height and distance but also, and these will make the construction harder. and if slump loss is too much, it will be difficult to cast, and these will be such defects as honeycombs and pothotes, and they will reduce the quality of construction
坍落度損失不僅直接影響到外加劑的使用效果，還大大制約了攪拌站的服務半徑以及泵送的高度和距離，給施工生產帶來很多不便，另外，坍落度損失過大還會造成澆築困難，導致混凝土中產生蜂窩、孔洞等缺陷，嚴重影響工程質量。When 20 percent cement is replaced by finely ground ti bfs in equal quantity, the hpc which initial flow ability can be improved greatly and its loss has been down. after 120min, the slump is 190mm, the spreading is 415mm, and the issue time is 15 seconds, which is absolutely applied to the pumping concrete
摻入20高鈦礦渣微粉，採用1 . 2的高效減水劑b可以得到塌落度、擴展度較大且損失較小的高性能混凝土， 120分鐘時，塌落度為190mm 、擴展度為415mm ，流出時間為15s ，符合泵送混凝土的要求。分享友人
