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。新回路采用FX2N-32MR型PLC设计了其控制系统,得出了新回路及其控制系统的特点,展现了PLC在工业控制领域的广阔应用前景。On basic of analyzing 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 curcuit 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. Meanwhile PLC controller is used in the new circuit.
