dredging pipeline 中文意思是什麼
-
This research is to eject some compressed air into the dredging pipe to get tri - phase flow in the pipeline, and research the change about the pipe resistance, at the same time, obtain the more effect adding gas method and realize reduction friction and prolong the dredging distance
本文研究的目的是在一定的漿體流速和漿體濃度下向輸送管道中加入一定量的氣體，在管道中形成三相流，進而探討加氣后管道流動的變化規律，同時確定出比較有效的加氣方案，從而實現減少阻力延長排距的目的。 -
Based on the technical requirements of manufacture, application and repair of the pump shell and cutter piece of the cutterhead pipeline dredge, put forward are the re - manufacture three principles on easily damaged workpieces of dredge engineering. with the inter - clamped structures on the pump liners, the gradient wear - resisting design on the cutter piece, and the new techniques in the process of re - manufacture, new wear - resistant materials, including high - cr alloy, overlaying and brazing deposits, and polymer adhesive coatings have been successfully applied to the re - manufacture dredge pump shell and cutter piece. the application results show that their wear - resistant lifetimes and the dredging profits have been increased remarkably
根據絞吸挖泥船泥泵絞刀的製造、使用和修復性能要求，提出了疏浚工程易損件再製造三原則；採用泥泵內襯互鎖結構、絞刀梯度化耐磨設計和工藝再製造新技術，將高鉻合金耐磨材料、熔敷耐磨材料及其復合材料和高分子耐磨膠粘塗層材料成功地應用於再製造泥泵殼和絞刀片上，顯著提高了泥泵殼和絞刀的耐磨壽命和挖泥船的疏浚效益。 -
This model studies the mixture forming process and simulates the specific gravity of the mixture in the pipeline under the different dredging conditions and work parameters, then refers the technical data in a real dredging project to make some simulation examples. in the end, based on this theory, some useful suggestions are given for efficient dredging. 2
該模型研究了在不同的疏浚環境和作業方式下吸口處泥漿的形成過程和計算泥漿比重的模擬模型，隨后結合實際工程數據給出了模擬實例，最後闡述了該模型對優化疏浚作業方法的指導意義： 2 、泥泵與管路系統。
