位于济宁兖州市的临沂矿业(集团)公司新驿煤矿对为井口绞车系统、井上下装卸、井下巷道喷浆、矿井风动机具、井下提斜吊梁提供压缩空气动力的不同类型空气压缩机混合工作状态进行科学分析,研究应用高压软启动与变频器自切拖动控制技术,同时对通讯、冷却系统进行自动控制改造,完善了故障报警、自动保护及在线监测功能,全过程实现人机分离,确保系统安全。(1)原空气压缩机系统运行状况。该矿现有5台空气压缩机,冷却系统均为水冷式。其中,3台为基建时期安装的活塞式空气压缩机,采用接点继电
Linyi Mining (Group) Company of Yanzhou City, Jining, China The Xinyi Coal Mine mixes different types of air compressors that provide compressed air power for the winch winch system, downhole loading and unloading, downhole roadway shotcreting, mine pneumatic tools, Work status of scientific analysis, research and application of high-voltage soft-start and drive self-cutting drag control technology, communication and cooling systems at the same time automatic control transformation, improved fault alarm, automatic protection and online monitoring, the whole process of man-machine separation , To ensure system security. (1) the original air compressor system operating conditions. The mine has five air compressors, cooling systems are water-cooled. Among them, three units for the construction of the Piston-type air compressor installed, the use of contact relay
