摘要
目的:通过对上海市质子重离子医院(SPHIC)质子重离子加速器设备(IONTRIS系统)冷却水系统故障进行分析,研究停机故障预防与应急优化方法,并评估这些方法的应用效果。方法:分析停机故障原因,实施停机故障预测诊断和改造方案。安装电压补偿器应对外电网波动,采用机械振动检测的方法预防水泵故障,设计并安装应急定压装置及故障快速切换系统应对定压装置故障,同时设计安装泄漏应急系统以降低水泄漏故障的风险。结果:实施优化应急方案后,提高了IONTRIS系统加速器冷却水系统故障应急能力。结论:大型医用设施的设计及运行需充分考虑安全性和冗余性的要求及故障诊断与应急的方案。
Objective:To research the prevention and emergency optimization of shutdownfault of cooling water system of proton and heavy ion accelerator,and elucidate theirapplication effect through analyzed the fault of cooling water system of accelerator(IONTRIS)in SPHIC.Methods:Through analyzed the reasons of shutdown faults,the predictivediagnosis and reconstruction scheme of shutdown fault were implemented.The voltagecompensator was installed for preventing the voltage fluctuation of external power grid.Andthe detection method of mechanical vibration was used to prevent fault of water pump.Theemergency constant pressure facility and rapid switching system of fault were designed andinstalled to prevent fault of constant pressure facility.At the same time,the emergency system of preventing leakagewas designed and installed to reduce the risk of water leakage.Results:After the optimal emergency schemewas implemented,the ability of fault emergency of cooling water system of proton and heavy ion accelerator wereenhanced and improved.Conclusion:The design and operation of large medical facilities need to fully consider therequirements for security and redundancy and scheme for faults diagnosis and emergency.
