摘要: 为减少旋挖钻机在作业时由负载波动所引起的功率匹配损失,提出了旋挖钻机动力头液压系统全局功率匹配节能控制方法。以220型旋挖钻机为研究对象,基于AMESim软件,建立了传统恒功率控制系统模型和全局功率匹配控制系统模型,并对比分析了不同的负载下的经济指标和性能指标。研究结果表明,全局功率匹配节能控制系统相比传统的恒功率系统节省燃油约6%,提高了能源利用率,延长了设备使用寿命。Abstract: To reduce the power matching loss of rotary drilling rig caused by the fluctuation of load during the construction process, a comprehensive power matching control strategy is proposed. Taking 220 kN·m rotary drilling rig as the research object and using the AMESim simulation software, the models for the traditional constant-power control system and the comprehensive power matching control system are set up and the comparisons of economic index and performance index under the different load are made. The results indicate that the comprehensive power matching control system can reduce the fuel consumption by 6% comparing with traditional constant-power control system, which improves the energy efficiency and prolongs the service life of equipment.
