本文就水电站压力管道充水过程的水力现象进行研究,提出通气孔由排气转为出水而引起管道内激烈的压力振荡是通气孔喷水的主要原因,并给出计算方法。
In this paper, the hydraulic phenomenon of the pressure pipe filling process in hydropower station is studied. It is proposed that the pressure oscillation in the pipe due to the venting from the exhaust gas to the outlet water is the main reason for the water injection in the pipe and the calculation method is given.
