摘要
在船用剪叉式升降机装置上,本文设计了一套采用PLC控制的电液比例控制系统,分析了电液比例控制系统的控制原理及特点。选用西门子公司S7-300 PLC实现开环控制,其控制方式灵活,调试方便,调速范围、稳定性和自动控制等方面具有明显优势。实际运行表明,该装置在四级及以下海况下运行平稳,上升、下降冲击都较小,取得了良好效果。
According to marine hydraulic scissor-fork lift, an electro-hydraulic proportional control system is designed and the electro-hydraulic proportional’s control principle is analyzed. The open control system has the flexible and intellectualized function, and excellence of control mode, little debug and good stability etc. In practice, the lift can work smoothly under Class 4 sea condition and less shock under up and down movement. It obtains a good effect.
