摘要
随着选煤设备自动化程度的不断提高,为提高原煤运输系统保护装置的自动化水平,屯兰选煤厂原煤拉运控制系统采用传感器对系统进行实时检测和自动控制。重点介绍煤仓料位检测原理,位置传感器、速度传感器的原理和安装要求。生产实践表明,采用传感器的保护控制系统应用不仅实现了设备运行状态和故障保护的精准控制,而且也实现了准确地对原煤运输设备运行参数进行测量,提高了生产效率,保证了生产线连续、可靠运行。
With the continuous improvement of the automation level of coal washery equipment,in order to improve the automation level of protective devices in the raw coal transportation system,real time detection and automatic control of the system were realized by sensors in the raw coal handling system of Tunlan Washery.The principle of coal bunker level detection,the principle and installation requirements of position sensor and speed sensor were introduced.The production practice showed that the application of sensor protection control system can not only realize the accurate control of equipment operation state and fault protection,but also measure the operation parameters of the raw coal transportation equipment accurately,which can improve the production efficiency and ensure the continuous and reliable operation of the production line.
