矿山高井深燃油管道垂直输送系统流动特性分析

Flow Characteristics of Vertical Transportation System for High Well Deep Fuel Pipeline in Mines

以金川集团股份有限公司龙首矿井下燃油管道垂直输送系统为研究对象,结合矿山实际情况,搭建燃油管道垂直输送系统仿真模型,计算了不同流速下输油管道内各节点的压力分布,分析了阀门关闭过程中不同质量流量以及不同阀门关闭时间下阀前阀后压力分布,提出了矿山高井深燃油管道垂直输送系统抑制水锤效应的方法。仿真表明,加装减压阀和止回阀,降低质量流量和增加阀门关闭时间可以有效减小或消除关阀过程产生的水锤效应。

Taking the vertical transportation system of underground fuel pipeline in Longshou Mine of Jinchuan Group Co.,Ltd.as the research object,combined with the actual situation of the mine,a simulation model of the vertical transportation system of fuel pipeline was built,and the pressure distribution of each node in the pipeline under different flow rates was calculated.The pressure distribution in front of and behind the valve under different mass flow rates and different valve closing times during the valve closing process was analyzed,and the method of suppressing the water hammer effect of the vertical transportation system for high well deep fuel pipeline in the mine was proposed.The simulation results show that the installation of pressure reducing valve and check valve,reducing the mass flow rate and increasing the valve closing time can effectively reduce or eliminate the water hammer effect caused by the valve closing process.
