日立盾构机流体系统再制造设计分析

Analysis of Remanufacturing Design of Hitachi Shield Machine Fluid System

本文阐述了天业通联2010年制造的含号盾构机的泡沫系统、注浆系统、推进系统的再制造设计,以上三个系统为旧机原配,通过再制造设计以后可以适应新的地质、新的管片规格要求,通过旧件的检测、分类、利用,最大程度的节约新购成本,满足功能需求。通过升级设计使其盾构机泡沫系统实现"单口单管单泵单控"功能,这也是行业内最新的设计要求。此外再制造后注浆系统的注入量提高一倍、注浆密封性能更好。推进系统能力得到提高,同时又防止管片出现"踩缝"风险。通过盾构机再制造的设计,充分的节约能源、成本,同时提高盾构机原机的工作能力。

This article describes the remanufacturing design of the foam system,grouting system,and propulsion system of the shield tunneling machine manufactured by Tianye Tonglian in 2010.The above three systems are the original equipment of the old machine and can be adapted to the new after remanufacturing design.Geological and new segment specifications,through the detection,classification,and utilization of old parts,the new purchase cost can be saved to the greatest extent,and the functional requirements can be met.By upgrading the design,the shield machine foam system realizes the function of"single port,single tube,single pump,and single control",which is also the latest design requirement in the industry.In addition,the injection volume of the grouting system after remanufacturing is doubled,and the grouting sealing performance is better.The capability of the propulsion system has been improved,while preventing the risk of"stepping on the seam"of the segment.Through the design of shield machine remanufacturing,energy and cost are fully saved,and at the same time,the working capacity of the original shield machine is improved.
