摘要
智能煤流控制系统通过收集采煤机和刮板运输机的功率、温度、电流等数据信息,进行智能化负荷调节,实现煤炭运输系统的科学合理运行。通过应用ABB智能煤流控制系统,具备智能启动控制、链条张紧自适应控制、煤量监测、智能调速、运行监控和工况检测等功能,智能化集控系统综合判断采煤机和运输机负荷情况,启动对采煤机割煤速度和运输机链速的匹配调节。应用结果表明,该系统能够根据主运输运煤能力自动调节工作面出煤量,避免了主运输过载现象;通过变频软启、自张链条和速度分级控制实现对设备和链条的有效保护,显著提高设备使用寿命;并能够自主调整采煤机牵引速度和截割功率,实现煤流系统的平稳运行和节能减排,降低开采能耗15%以上。
The intelligent coal flow control system conducts intelligent load regulation by collecting data information such as the power,temperature,and current of the coal shearer and scraper conveyor to realize the scientific and reasonable operation of the coal transportation system.The ABB intelligent coal flow control system was applied,which has functions such as intelligent start control,chain tension adaptive control,coal quantity monitoring,intelligent speed regulation,operation monitoring and working condition detection,through the intelligent centralized control system comprehensively judged the load of the shearer and the conveyor,and started the matching adjustment of the shearer′s coal cutting speed and the conveyor chain speed.The application results show that the system can automatically adjust the coal output of the working face according to the main transportation coal transportation capacity,avoiding the main transportation overload phenomenon,realized the effective protection of equipment and chains through frequency conversion soft start,self-tensioning chain and speed classification control,significantly increase the service life of equipment,and can independently adjust the traction speed and cutting power of the shearer to realize energy saving and emission reduction,and reduce the unit power consumption of mining by more than 15%.
