基于故障树诊断的烟尘回收装置优化

Optimization of Smoke and Dust Recycle Device Based on Failure Tree Diagnosis

为了找出焊管等离子在线切割烟尘回收装置回收失灵的原因,建立了基于故障树诊断的烟尘回收失灵故障树,并以某公司7套烟尘回收装置2009—2013年出现的各种故障为底事件进行了优化分析。分析结果表明,皮带损坏、滤芯受潮进水和滤芯漏风等是烟尘回收失灵的主要原因,提出了相应的优化措施。改造优化后的分析及实际使用结果表明,此次优化改造降低了烟尘回收失灵故障率,有效降低了车间内的烟尘污染,净化了生产环境。

In order to find out the failure reason of smoke and dust recycle device of welded pipe plasma on-line cutting, the smoke and dust recycle failure tree was established based on failure tree diagnosis, and the optimized analysis was carried out for various kinds of faults occurred in a company＇s seven sets of smoke and dust recycle device during 2009—2013. The results indicated that the belt damage, the filter element be affected with damp, filter air leakage are the main reason of dust recycle failure, put forward the corresponding optimization measures. The actual application showed that the optimized transformation reduces the recycle failure, effectively reduces the soot pollution in workshop, and purify the production environment.
