空壓機長時間停用導致設備故障
長(chang)期(qi)停用導致設備(bei)毛病:
毛病現(xian)(xian)象:某電(dian)廠氣力輸(shu)灰(hui)體(ti)系共裝置有4臺(tai)螺(luo)桿式(shi)空(kong)(kong)壓(ya)機(ji)用(yong)(yong)做輸(shu)送氣源,正常運(yun)(yun)(yun)轉(zhuan)(zhuan)時(shi)(shi)3臺(tai)空(kong)(kong)壓(ya)機(ji)運(yun)(yun)(yun)轉(zhuan)(zhuan)一(yi)臺(tai)備用(yong)(yong),備用(yong)(yong)空(kong)(kong)壓(ya)機(ji)定時(shi)(shi)切換時(shi)(shi)刻為(wei)一(yi)個(ge)月。運(yun)(yun)(yun)轉(zhuan)(zhuan)值班人(ren)員(yuan)(yuan)將空(kong)(kong)壓(ya)機(ji)有備用(yong)(yong)切換到運(yun)(yun)(yun)轉(zhuan)(zhuan)狀況,運(yun)(yun)(yun)轉(zhuan)(zhuan)不(bu)到2min,只聽一(yi)聲悶響,空(kong)(kong)壓(ya)機(ji)的運(yun)(yun)(yun)轉(zhuan)(zhuan)時(shi)(shi)刻突然改動,運(yun)(yun)(yun)轉(zhuan)(zhuan)人(ren)員(yuan)(yuan)查看(kan)發現(xian)(xian)空(kong)(kong)壓(ya)機(ji)油氣桶油面鏡看(kan)不(bu)到一(yi)點油位,立刻中止(zhi)空(kong)(kong)壓(ya)機(ji)運(yun)(yun)(yun)轉(zhuan)(zhuan),關(guan)閉出(chu)口門,空(kong)(kong)壓(ya)機(ji)體(ti)系泄壓(ya)后依然看(kan)不(bu)到油位。
通知檢(jian)修人員(yuan)查看,置疑油(you)氣分離器濾芯破損導致潤滑(hua)油(you)抽走,檢(jian)修人員(yuan)的當即查看空壓機,結果(guo)發現油(you)氣分離器濾芯已被嚴峻(jun)變(bian)形(xing),并決裂(lie)一(yi)道口兒,油(you)氣桶底部剩余少數(shu)潤滑(hua)油(you)。
原因剖析:備用(yong)空(kong)壓機(ji)停(ting)(ting)用(yong)多久合適(shi),各地(di)不同的(de)(de)氣候(hou)條件可以作出不同的(de)(de)選擇;在該(gai)廠已經呈(cheng)現過空(kong)壓機(ji)備用(yong)停(ting)(ting)運(yun)一(yi)(yi)個(ge)月后,再次發動時呈(cheng)現油氣分(fen)離器濾芯阻(zu)塞報的(de)(de)警(jing),說明在該(gai)廠空(kong)壓機(ji)不適(shi)合停(ting)(ting)用(yong)一(yi)(yi)個(ge)月的(de)(de)時刻,但卻沒有引起運(yun)轉部(bu)分(fen)的(de)(de)注意(yi)。
空(kong)壓機距前(qian)次(ci)保養(yang)只要(yao)2000h,因為長期停機,油氣分(fen)離(li)(li)器濾(lv)芯(xin)上粘附(fu)(fu)的(de)油垢灰(hui)分(fen)等干結,形(xing)成油氣分(fen)離(li)(li)器濾(lv)芯(xin)流通面積減少,發(fa)動空(kong)壓機后分(fen)離(li)(li)器粘附(fu)(fu)新的(de)油分(fen),流通面積進一步減少,隨之被分(fen)離(li)(li)器前(qian)后大(da)的(de)壓差擠壓變形(xing)決裂(lie),導致潤滑油被抽走。
