【摘要】：某銅冶煉廠風(fēng)機(jī)運(yùn)行時(shí)間不足一個(gè)月即發(fā)生飛車事故,輪蓋及葉片整體從輪盤上斷裂脫落。分析表明,風(fēng)機(jī)進(jìn)口管路設(shè)計(jì)不合理,大量酸液沖擊腐蝕風(fēng)機(jī)葉輪是事故發(fā)生的根本原因。通過改進(jìn)現(xiàn)場(chǎng)的進(jìn)口管路,有效減少了進(jìn)入風(fēng)機(jī)的酸液,葉輪受到的沖擊腐蝕明顯減弱,風(fēng)機(jī)的工作環(huán)境得到極大改善,確保了風(fēng)機(jī)的正常運(yùn)行。目前風(fēng)機(jī)使用狀況良好,改進(jìn)效果顯著。
[Abstract]:The running time of fan in a copper smelter is less than one month, and the wheel cover and blade are broken off from the wheel disc. The analysis shows that the design of fan inlet pipeline is unreasonable, and a large amount of acid impingement corrosion is the root cause of the accident. By improving the inlet pipeline in the field, the acid entering the fan is effectively reduced, the impeller is obviously weakened by impact corrosion, the working environment of the fan is greatly improved, and the normal operation of the fan is ensured. At present, the fan is in good condition and the effect of improvement is remarkable.
