摘　　要：在分析现有基本回路的基础上 ,文中提出了一种两调速阀串联二工进速度换接的新回路 ,并对其来源、组成、原理、特点及其在动力滑台双泵供油二工进液压系统新回路中的应用进行了阐述。新回路具有各调速阀可独自调节与能量消耗较低等新特点。 (而现有回路则刚好相反。)On basic of analysing hydraulic circuit of nowadays,a new hydraulic circuit has been designed.There are two speed control valves and changes of two work speeds in the new hydraulic circuit.This paper introduces origin,formation,principal,feature and application in a new circuit of double pumps hydraulic system of modular machine tool's power sliding feed table. In the circuit,every speed control valve is adjusted alone. The useless power of new circuit is lower than the circuit nowadays.
