摘要
调压室是减小水锤压力传递的有效方法,调压室断面受托马稳定条件制约,阻抗孔直径是托马稳定断面的重要参数之一。通过对北疆某水电站调压室的稳定需求给出较合适的断面积,通过阻抗孔对调压室体型进行优化设计,主要涉及阻抗孔口尺寸、顶板、底板设计高程及运行工况等因素。
Surge chamber is an effective method to reduce the water hammer pressure transmission , surge chamber section is restricted by Thomas stability conditions , impedance hole diameter is one of the important parameters in Thomas stable section , based on the basal area of a hydropower station diversion are stable demand pressure chamber isappropriate , optimization design of the body through theimpedance surge chamber hole , mainly relates to an impedance orifice size , roof, floor elevation design andoperating conditions.
