Control optimization methods and practice on medical proton and heavy ion synchrotron cooling water system
摘要
Abstract
Objective To study the temperature control method of the cooling water system for Siemens medical proton and heavy-ion synchrotron.Methods The return water temperature was used as the input variable of the control program,temperature prediction method was applied to controlling valve opening,and the capacity of water tank at backwater-side was increased to enhance temperature buffer capability.Results The optimized system adapted itself to multi loading conditions of the synchrotron,which achieved 2 ℃ peak elimination in case of return water at 32 ℃ or less to limit the input water temperature within (27±1) ℃.The failure rate of temperature deviation was decreased from 64% to 8%.Conclusion The optimized cooling water system with three-layer structure fulfills the requirements of Siemens proton heavy-ion synchrotron operation.关键词
