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。
Santanghu Oil Pipeline over the Tianshan twice, a larger gap, prone to water hammer, leading to the pump unit and stop the valve suddenly closed, so that the pump inlet and outlet side and the valve before and after the generation of high and low pressure wave. In order to prevent the high-pressure wave exceeds the maximum allowable working pressure and lead to pipeline rupture, low-pressure wave steady flow of pressure when the pipeline is lower pressure and induce pump cavitation, based on the actual situation Santanhu crude oil pipeline, by taking the pipeline electric Valve pressure regulation, installation of pressure relief valve and across the board ahead of water hammer protection and other multiple protection measures to prevent the occurrence of water hammer damage.
