法国SIRUS-400型采煤机是我国引进数量较多的一种机型。西山矿务局1979年引进该机12台,主要问题是牵引部主泵缸体和配电油盘磨损较快,主泵平均使用寿命不足1000h。为了解决这一难题,1982年底,西山矿务局组织了技术攻关,并请山西矿业学院作技术指导,对该机牵引部进行测试消化和技术改造。经过四年多的共同努力,对主泵、过滤器、冷却器和补油泵相继作了改进,延长了主泵使用寿命,提高了采煤机工作的可靠性。
France SIRUS-400 shearer is introduced in China a large number of models. Xishan Mining Bureau introduced the aircraft in 1979, 12 sets, the main problem is the traction Department of the main pump cylinder block and distribution wear faster, the average life of the main pump less than 1000h. In order to solve this problem, the end of 1982, Xishan Mining Bureau organized technical research, and asked Shanxi Mining Institute for technical guidance, the traction unit of the aircraft for testing and digestion and technological transformation. After more than four years of joint efforts, the main pumps, filters, coolers and charge pumps have been improved successively to prolong the service life of the main pump and improve the reliability of the work of shearer.
