摘　　要：液压调速系统一般分为有级调速系统和无级调速系统,无级调速又可分为节流调速、容积调速与容积节流调速等。在对有级调速系统与无级调速系统进行分析与介绍的基础上,提出一种改进后的复合调速系统。复合调速系统具有调速范围广、低速性能佳、结构简单、维护方便等优点,可以减少能量损失,提高效率。Hydraulic speed regulating system is generally divided into step speed regulation system and stepless speed regulation system, stepless speed regulation can be divided into throttle governing, volumetric governing and volumetric throttle governing. Based on the analysis and introduction of the step speed regulation system and stepless speed regulation system, an improved compound speed regulation system was proposed. Compound speed regulating system has the advantages of wide speed adjustable range, sound performance at low speed, simple structure, easy maintenance, etc. and it can reduce energy loss and improve efficiency.
