摘要:
地下洞库储存油品自由卸油落差大，进洞库的落差管段中液流流动状态特殊，若设计不当可能引发落差管水锤振动、负压气蚀、气液混合等一系列负面问题。基于对大落差管的水力工况分析，应用能量方程进行洞库大落差管实例水力计算和分析论证，结果表明：落差管在空管投油的不稳定过程中，惯性水头起阻力作用，消耗了落差管中的剩余能量；在稳定生产过程中，适当减小管径、在落差管下端增设水平管、增加局部能量消耗部件，是增加能耗行之有效的处置技术。
Abstract:
The oil stored in cavern has a big free fall，and the flowstate of fluid within the inlet pipe is special. The improper design may trigger the fall pipe vibration from water hammer，negative pressure cavitations，gas-liquid mixture and a series of problems. Based on the hydrodynamic condition analysis of big fall pipe，energy equations were applied to hydraulically calculate and demonstrate a cavern case. Results showed that in the instability process of "empty pipe" under the condition of running，inertia head of the fall pipe played a role of "resistance"，which consumed the residual energy in the fall pipe. In a stable production process，to properly reduce the diameter of big fall pipe，install a horizontal tube with a certain length at the bottom of the fall pipe and set up some energy-consuming components are reasonable and effective disposal technology to speed up the energy consumption.
