摘要
为进一步提高煤层气钻机的自动化水平,尽量减少司钻的操作,提高设备自检能力,研制了MC90Y煤层气车载专用钻机。该钻机采用电液控制方式,PLC控制器集中控制,起升和旋转系统使用比例容积泵调速,辅助系统采用恒压变量泵提供动力;起升系统采用平衡阀回路设计,实现了正载荷、负载荷和变载荷情况下的平稳运行;采用手柄方位辨识控制,降低司钻的操作复杂性,优化起升和旋转系统的运行;控制系统具有自检、监测和自锁保护等功能,提高了钻机的安全保护能力。测试及现场应用结果表明,该钻机操作便捷,可控性好,运行平稳。
To make a further improvement of the automation level of coal bed methane （CBM） drilling rig, reduce the driller operation to the minimum and improve the self-checking capacity of equipment, the MC90Y CBM truck-mounted drilling rig was developed. The rig adopts the electro-hydraulic control mode and centralized control of the PLC controller. The hiosting and rotating system uses the proportional volumetric pump for velocity regula- tion. The auxiliary system adopts the constant pressure variable displacement pump to supply power. The hoisting system adopts the balance valve loop design to achieve a smooth operation in positive load, negatiye load and varia- ble load. The handle orientation control is adopted to reduce the operating complexity of the driller. The operation of the hoisting and rotating system is optimized. The control system has the functions of self-check, monitoring and self-locking protection, improving the safety and protection capacity of the rig. The testing and the field application show that the drilling rig is simple in operation, desirable in control and smooth in operation.
