宣钢龙烟铁矿是一座中型地下铁矿。往复式空气压缩机是采掘生产的主要供气设备,拥有各种类型的空气压缩机40余台,运行20年以上的空压机占60％。一九七五年该矿学习外地经验,将无油润滑技术应用在 1-40/8空气压缩机上,取得了成功。到八○年全矿已有12台1-40/8型空压机利用填充聚四氟乙烯活塞环实现了气缸无油润滑,在节油降耗、减少维修费用、提高设备完好率、获得纯净压缩气体及改善生产条件等方面均取得了明显效果。 Xuan Gang Long Zhan iron ore is a medium-sized underground iron ore. Reciprocating air compressor is the main gas production equipment, with various types of air compressors more than 40 units, more than 20 years of operation of air compressors accounted for 60%. In 1975, the mine learned field experience and successfully applied the oil-free lubrication technology to 1-40 / 8 air compressors. By the end of 1980, 12 1-40 / 8 air compressors in the whole mine had realized the cylinder oil-free lubrication by filling the polytetrafluoroethylene piston ring, saving fuel, reducing maintenance costs, improving equipment availability, Pure compressed gas and improve production conditions have achieved significant results.
