Abstract
本发明属于煤矿综采工作面液压供液技术领域，且公开了综采工作面设备列车阀组供液反冲洗装置，本发明正常供液时，第二电磁阀开启、第一电磁阀关闭，密封塞封堵排料口，高压乳化液进入过滤腔经滤芯过滤后，洁净液输送至阀组，为综采工作面设备列车稳定供液，当滤芯积杂使进出液压差达到预设阈值时，自动切换电磁阀、打开排料口，水箱中的洁净液经喷头高压冲洗滤芯内壁，伺服电机通过齿轮传动带动清洗组件绕滤芯回转，清洁刷与刮板配合往复运动，彻底剥离滤芯内外杂质，冲洗废液由排污口汇入回收箱集中收集，实现全自动完成滤芯清洗，无需人工拆解更换，降低井下劳动强度，稳定供液压力，有效提升综采设备列车阀组供液可靠性。
