气压式调压室的应用研究

Study on Application of Air Surge Tank

压力水系统中设置气压式调压室是防护水锤事故的、新的、经济有效的措施.对水泵扬水的长距离压力输水系统中设置新型气压式调压室,建立了实验模型和相应的数学模型;进行了理论分析研究、数值模拟和实验研究;通过实验,验证了数值模拟的数学模型和计算程序,为电站和泵站的优化设计提供了应用气压式调压室的理论依据和计算水泵断电后气压式调压室中水位波动的计算软件.

Installing air surge tank in pressure water system is a new and economically efficient measure to prevent water hammer accident. The authors set a new type air surge tank in the long-distance water delivery system of pump, built experimental mode and its corresponding mathematic model, and made the theoretical analysis, numerical and experimental study on the models. Through the analysis, the mathematic model simulated by numerial value and its calculation programme is testified so as to provide the theoretical basis of applied air surge tank for the optimum design of power station and pump station, and provide the calculation software of water level fluctuation in air surge tank after pump power-off.
