水电站调压室设置必要性判式的分析研究

Analysis on the necessary formula of setting up surge tank for hydropower station

【目的】探寻一个更为直接、细化的考虑多因素的水电站调压室设置的必要性判式。【方法】在分析和理解传统的水电站调压室设置判式的基础上,阐述了其在实际应用过程中需反复调整参数及未直接考虑材料强度的不足,依据设备允许的承压要求提出新判式,并对新判式的实用性进行了验证。【结果】利用新判式计算结果更为符合工程实际,达到了预期的研究目的。【结论】新判式可提供一个较为客观准确的"数量值",作为调压室设置与否的判据。

[Objective] The studry probed into a more direct and detailed formula of setting up surge tank of hydropower station. [Method] On the basis of analysing traditional formula,which didn＇t take account of repeatedly adjusting parameters and the strength of material,a new formula was put forward according to the equipments＇ pressure-tolerance. [Result] The new formula agrees with reality ,achieving the aim of the study. [Conclusion] The new formula can provide an objective and correct value,and can be regarded as the discriminant for setting up surge tank.
