精密液压容积调速系统

SPEED COWTROL SYSTEM OF AN ACCURATE HYDRAULIC PUMP-MOTOR

本文设计了一种精密液压容积调速系统，此系统由一种带补偿器的变量泵和一定量马达组成，利用系统中调节元件的检测作用使系统形成闭环控制，从而提高了系统的刚性和调速范围，而且结构简单、调速方便，易于实现系统的程控和自控．

his paper presents a system of accurate hydraulic pump-motor regulating speed.The system consistS of a varisble pump with a compensator and a fixed motor,using the inspecting funtion of a regulating element to form closed loop control.Therefore,the system's rigidity and the range of speed are improved. The system is simple in structure and covement in regulation, and it is easy to realize the system's process control and automation.
