以新巨龙公司2301S工作面成套设备再制造为例,系统地介绍了采煤机、液压支架、刮板输送机等煤矿综采成套设备再制造关键技术及其先进性与创新性。实践证明煤矿综采成套装备再制造优化了产品的结构,提升了关键零部件及整套装备的机械性能及使用寿命,减少了设备更换检修时间、提高了矿井生产效率。 Taking the remanufacturing of complete sets of equipment of 2301S working face of New Dragon Company as an example, the key technologies, advanced features and innovations of remanufacturing complete sets of coal mining equipment in coal mines, hydraulic supports, scraper conveyors and so on are systematically introduced. Practice has proved that re-manufacturing of fully mechanized mining equipment in coal mines has optimized the structure of products, improved the mechanical properties and service life of key components and equipment, reduced the time for equipment replacement and maintenance, and improved the mine production efficiency.
