【摘要】 本文分析了目前大型调速器容量选择中存在的问题，论证了用主配压阀流量特性表征大型调速器容量的合理性，提出了求取主配压阀流量特性的“压力过程法”。探讨了主配压阀流量特性在大型调速器容量选择中的应用，对如何贯彻《水轮机电液调节系统及装置技术规程）ＳＤ２９５—８８中有关主配压阀流量特性的规定提出了初步看法。更多还原

【Abstract】 ID. this paper, several problems existed in the selection of capacityfor large turbine governor were analysed.The rationality that flow characteristics of the main distributing ralve represent the capacity of large turbine governor’ was demostrated. The method of pressure process curve used for acquiring flow characteristrcs of main distributing valve was proposed. The applica tion of the flow oh4racteristic to selecting capacity of the large turbine governor was developed The initial idea about how to carry out the regulation in"specification of eletro-hydraulic syStem and unit for hydraulic turbine" for the main distributing valve are presented.更多还原
