摘要:
北方山区某温泉超长距离输送工程全长为48.146 km，流量为60 m3/h，通过导热模型计算温泉输送过程的导热情况，以确定温泉沿程温度。然后以冬季最冷月温泉平均温度为条件，得出管道水力坡降，配合管道沿线高程，确定了中途加压泵站的位置和扬程。基于温度对水力坡降及管道强度的影响，对不同环境温度下管道强度进行复核，合理选择普通或耐热管材。之后对水泵启停时的水击增压进行计算，检验水锤对管道强度的影响，进行水锤预防设计，采用缓启缓闭措施减小水锤的影响。最后确定适合于该温泉输送系统的工程运行方案,确保运行稳定。
Abstract:
The total length of a hot spring transportation project in mountain area in northern China is 48.146 km, the flow rate is 60 m3/h. The heat conduction of the hot spring transportation process was calculated with heat conduction model to determine the temperature along the pipeline. On the condition of the average temperature of the coldest hot spring in winter, the hydraulic slope of the pipeline was obtained, and the position and head of the pressure pumping station in midway were determined with the elevation along the pipeline. In view of the influence of temperature on hydraulic slope and pipe strength, the pipe strength under different ambient temperature was checked, and the common or heat-resistant pipe was selected reasonably. After that, the water hammer pressure was calculated, the influence of water hammer on pipe strength was tested, and the water hammer prevention design was carried out, and the measures of slow opening and slow closing were adopted to reduce the impact of water hammer. Finally, the project operation scheme suitable for the hot spring transportation system was determined to ensure stable operation.
