三塘湖原油管道水击保护措施
Measures in surge control in Santanghu Oil Pipeline
-
摘要: 三塘湖输油管道两次翻越天山,落差较大,易发生水击,导致输油泵机组和进站阀门突然关闭,使泵进出口侧和阀前后产生高低压波。为了防止高压波超过最大允许工作压力而导致管道破裂,低压波使稳态运行时压力较低管道的液流分离而诱发输油泵汽蚀,基于三塘湖原油管道的实际情况,通过采取管道电动阀调节压力、安装泄压阀和全线超前水击保护等多重保护措施,可以避免水击危害的发生。Abstract: Santanghu Oil Pipeline with tight-line process twice crosses over the Tianshan Mountain, and surge is easy to occur due to the great fall. To effectively control the surge, multiple control measures are adopted, including setting up the power regulating valve to control pressure, installing pressure relief valve and lead protection against the surge for the whole pipeline based on the actual running condition of the oil pipeline.
