Design and Characteristic Analysis of Variable Speed Hydraulic System

摘要

The motor variable frequency speed control technology applied to the traditional hydraulic system based on variable speed hydraulic transmission principle with The PLC technology,hydraulic control,detection technology and configuration of organic,it combine PLC as the core of the lower machine control components,PC as the control,researched the variable speed hydraulic test system hardware,software and control systems design.The experiments were performed,realized the variable speed hydraulic experimental platform for open loop control and variable speed hydraulic system parameters real-time monitoring and dynamic display.It overcomes some of the shortcomings of the conventional hydraulic system,improved the efficiency,the hydraulic system run more smoothly and reduce noise.The experiments show that the variable speed hydraulic test bench run well and achieve the purpose.
