- 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.
