本文以流体力学、控制理论为基础,对限压式变量泵与调速阀组成的调速系统的工作原理、静动态性能进行了较全面的理论分析,并对系统的设计、调整等问题作了有益的探讨,为容积—节流联合调速系统的推广使用提供理论基础。
Based on the theory of fluid mechanics and control theory, this paper makes a comprehensive theoretical analysis of the working principle and the static and dynamic performance of the variable speed variable displacement pump and the speed regulating valve, and makes some suggestions on the design and adjustment of the system A useful discussion to provide a theoretical basis for the popularization and application of volume-throttle joint speed control system.
