坑道钻机变频调速系统设计及仿真

Design and Simulation of Inverter Speed Control System for Pit Drilling Rigs

通过对ZDY型坑道钻机的实际运行工况进行分析,并基于液压回转回路系统进行变频调速设计,通过在不同负载条件下控制液压系统流量对坑道钻机输出速度以及输出转矩进行灵活调节。通过仿真分析可以看出,该控制系统在遭遇突变负载时能够快速进行自适应调节,调节速度较快,可以满足实际钻探需要。

By analyzing the actual operating conditions of the ZDY type pit drilling rig and designing the frequency conversion speed control system based on the hydraulic rotary circuit system,the output speed and torque of the pit drilling rig can be flexibly adjusted by controlling the flow rate of the hydraulic system under different load conditions.The simulation analysis shows that the control system can quickly adjust itself when encountering sudden load changes,and the adjustment speed is fast enough to meet the actual drilling needs.
