摘要
该文介绍了一种适用于中小型水轮机调速器的液压控制系统,它由电磁方向阀和电液比例阀构成的并联系统完成自动调节控制。此系统采用标准液压元件,结构简单,维护方便。实验证明它能完全满足水轮机调速器液压控制系统的各项要求,并且由于采用开关阀和比例阀,大大提高了系统的抗油污能力,使系统可靠性增加。
In this paper, a parallel connected hydraulic control system for hydraulic turbine speed governor is discussed in detail. Parallel connected directional valve and proportional valve are used to form the automatic control unit. This system is simple and easy to maintain, is very suitable for hydraulic turbine speed governor with small or medium capacity
