本文是针对挪威气压式调压室中无任何阻抗的情况,提出采用阻抗式调压井和气压式调压室相结合,以减少气压式调压室体积的建议。文中以实际工程为背景对上述建议进行了水电站系统水轮机调节稳定和水轮机处水击压力升高的验算,得出如果选择适当的阻抗孔口,气压式调压室的体积可大大减少的结论。本文方法也可用于气压式调压室等效竖井面积A_(ecu)和阻抗孔口进行优化。
This article is aimed at Norway pressure surge chamber without any impedance, the use of resistance surge tank and pressure surge chamber combined to reduce the size of the pressure surge chamber. Based on the actual engineering background, the above suggestions are taken to verify the stability of the turbine of the hydropower station and the increase of the water hammer pressure at the turbine. It is concluded that the volume of the pneumatic surge tank can be greatly reduced if the appropriate impedance orifice is selected. The method of this paper can also be used to optimize the equivalent shaft area A_ (ecu) and the impedance orifice of a pneumatic surge chamber.
