摘要/Abstract

摘要：

泄漏速率是计算泄漏量、确定泄漏持续时间及评估泄漏风险的前提和基础，通过搭建液相储罐小孔泄漏实验系统，构建不同泄漏场景，对比液位控制系统干预下的泄漏速率变化情况，并结合泄漏速率模型计算值进行分析。结果表明：液位控制系统响应后，泄漏速率下降速度变缓，并随时间推移逐渐开始回升，最后稳定在某值处达到稳态泄漏，进出流量对储罐小孔泄漏速率的影响基本可忽略。通过改进储罐泄漏经典公式，建立基于实际液位控制系统干预条件下的储罐小孔泄漏速率模型，提出泄漏孔口高压修正系数计算方法和模型，通过验证分析证明该模型可有效提高液位控制系统干预下泄漏速率计算精度。

Abstract:

Leakage rate is the premise and basis of leakage mass calculation, leakage duration determination and leak risk assessment.Through building a tank experiment system of liquid hole-leakage for different leak scenes and contrasting the variation of the leakage rate under the interventions of the liquid level control system, an analysis is carried out combined with the calculation of leakage rate model.The result shows that after the response of liquid level control system, the leakage rate reduces slowly and gradually increases as time goes on.Finally, the leakage rate stays in a stable leakage state.The influence of the flow rate on the hole-leakage rate of the tank can be neglected.Hole-leakage rate model of tank based on the actual liquid level control system is built through improving classic formula of tank leakage.The calculation method and the model of high pressure hole-leakage correction coefficient are proposed.By verification, the model can efficiently improve the calculation accuracy under the interventions of the liquid level control system.

Key words: liquid level control, leakage rate, model, experimental validation, safety
