【摘要】 针对阻抗式调压室不能完全反射水电站压力钢管传来的水击波的实际特性,导出了阻抗式调压室的阻抗系数和该处水击波透射系数之间的关系;以水击计算的特征线法为基础,提出了考虑调压室对水击波不完全反射时的水击压强计算方法;实例对比说明,设置阻抗式调压室时,不仅阀门处的水击压力比用常规方法计算的值高,而且引水隧洞也承受着一定的水击压力。更多还原

【Abstract】 In allusion to the characteristic of resistance surge chamber reflecting incompletely water hammer from pressure tube,this paper studied the relation between the coefficient of resistance and the coefficient of pressure transmission.Based on the characteristic method,this paper brought forward a method of calculation about water hammer reflecting incompletely water hammer wave,calculated and analyzed a actual example,the result indicated that the pressure of water hammer in the pressure tube and diversion tube is higher,compared with using the method of calculation about water hammer in throttled surge tanks reflecting completely water wave.更多还原
