- 摘要:
- 西气东输二线部分管道采用X80直缝钢管,常规的3PE防腐层涂敷过程会对X80直缝钢管力学性能产生不利的影响。针对X80直缝钢管对防腐层的涂敷温度要求,研究了可在低温下(在185~195℃温度范围内)固化的3PE防腐涂层及低温涂敷工艺,而涂层的性能能够达到常规涂敷(200~230℃涂敷)的3PE防腐层性能,满足西气东输二线管道工程对3PE防腐层的防腐性能要求。
In petrochemical enterprises,centrifugal pumps are frequently running in non -design status.Their operational flows are below the design values and there exist problems of low efficiency, high energy consumption and instable operation, etc. With the angle adjustment method changing the angle of blades' entrances and blades' curvature, the hydraulic loss in impeller flow path can be reduced. The best working condition of the centrifugal pump in non-design status can be found by using the software CAD to establish 3D model of centrifugal pump impeller, applying the software of ANSYS to analyze stress and generate meshes,and at last, introducing the mesh file into the software FLUENT to performance numerical simulation.2009,03(03): 35-36 收稿日期:2008-7-22分类号:TE988.2作者简介:张其滨(1964-),男,江西人,教授级高级工程师,1987年毕业于大连工学院,获硕士学位,2003年获美国MBA学位,主要从事防腐保温技术的研究和监督检验等工作。参考文献:
