压力管道的管理,是泵站管理工作的重要一环,其维护的好坏,不仅关系到水泵运行效率,而且有关泵站的安全。目前压力管道多为钢管、铸铁管、预应力钢筋砼管。对于离心泵泵站,南方地区多是扬程低、管径小、管道短,采用一机一管或二机一管;北方地区扬程高、管径大、管路长,地形条件复杂,多数采用三机一管或 The management of pressure pipelines is an important part of pump station management. The quality of its maintenance is not only related to the efficiency of pump operation, but also the safety of pumping stations. At present, most of the pressure pipes are steel pipe, cast iron pipe and prestressed reinforced concrete pipe. For centrifugal pumping station, the southern region is mostly low lift, small diameter, short pipe, using a machine or a machine two tubes; the northern head of high, large diameter, long pipelines, the terrain conditions are complex, the majority of the use of Three machines or a tube
