往复式活塞隔膜泵单向阀故障自动诊断技术

摘要

As the development of China economy,the areas such as mine industry,nonferrous industry and chemical industry continue to grow and develop,in which reciprocating piston diaphragm pump used for the transportation of mineral slurry,alumina stripping,chemical reaction furnace feeding has been widely applied.Because of many reasons,the phenomenon like check valve failure and leaking always exist in the equipment,which bring a lot of harm to technical system.The reason for check valve failure was analyzed in this paper and the automatic diagnosing and alarming technology was developed,which can effectively avoid or reduce the harm of check valve failure.%随着我国经济持续增长,国内的矿山、有色、化工等领域不断发展壮大,其中用于矿浆输送、氧化铝溶出、化工反应炉喂料等方面的往复式活塞隔膜泵也得到了大量应用,由于多种原因设备经常会出现单向阀卡阀、泄漏现象,给设备和工艺系统带来很大危害。文章从隔膜泵工作机理方面入手,分析了单向阀故障产生的原因,提出了单向阀故障的自动诊断及报警技术,可以有效避免或减轻单向阀故障带来的危害。
