3c消防排煙風機在運用時會呈現脫離現象,下面我們就一起來剖析一下,,對于通常的3c消防排煙風機,人們只需在慣例條件下測試就能夠滿足要求,然而屋頂風機卻不同,由于它不但要在慣例條件下正常動作,并且在發生火災的情況下也要正常運轉這就為3c消防排煙風機的測試帶來了一定的困難。
要使反常(chang)3c消防排煙風(feng)(feng)(feng)(feng)機(ji)(ji)(ji)快速(su)脫離失速(su)工況(kuang)點組織(zhi)專人擔任調整引、送(song)(song)風(feng)(feng)(feng)(feng)機(ji)(ji)(ji),多葉(xie)排煙口(kou)至少兩(liang)人協(xie)作操作,分工明(ming)晰要敏捷解列失速(su)送(song)(song)風(feng)(feng)(feng)(feng)機(ji)(ji)(ji)自動(dong),當即關小(xiao)(xiao)失速(su)送(song)(song)風(feng)(feng)(feng)(feng)機(ji)(ji)(ji)的動(dong)葉(xie)開度,使動(dong)葉(xie)開度小(xiao)(xiao)于百分之四十,在送(song)(song)風(feng)(feng)(feng)(feng)機(ji)(ji)(ji)并排運轉(zhuan)情況(kuang)下,同步(bu)快速(su)關小(xiao)(xiao)別的1臺未失速(su)送(song)(song)風(feng)(feng)(feng)(feng)機(ji)(ji)(ji)動(dong)葉(xie),使并排運轉(zhuan)的兩(liang)臺送(song)(song)風(feng)(feng)(feng)(feng)機(ji)(ji)(ji)動(dong)葉(xie)開度,電流相(xiang)靠近,3c消防排煙風(feng)(feng)(feng)(feng)機(ji)(ji)(ji)廠家脫離失速(su)區后,風(feng)(feng)(feng)(feng)機(ji)(ji)(ji)出(chu)口(kou)風(feng)(feng)(feng)(feng)壓(ya)、二(er)次(ci)風(feng)(feng)(feng)(feng)箱風(feng)(feng)(feng)(feng)壓(ya)上升,爐膛(tang)負壓(ya)呈現(xian)大幅不堅(jian)定,應立馬調整爐膛(tang)負壓(ya),然后堅(jian)持(chi)爐膛(tang)負壓(ya)正常(chang)。
在(zai)葉(xie)(xie)輪(lun)運(yun)轉(zhuan)(zhuan)初期(qi)(qi)及一切定(ding)期(qi)(qi)查(cha)看(kan)(kan)的時分,只(zhi)需一有(you)時機,都(dou)有(you)必(bi)要查(cha)看(kan)(kan)葉(xie)(xie)輪(lun)是否(fou)呈現裂紋、磨損(sun)、積塵(chen)等(deng)缺陷。只(zhi)需有(you)可(ke)能(neng)(neng),都(dou)有(you)必(bi)要使葉(xie)(xie)輪(lun)堅持清潔(jie)狀(zhuang)態,并定(ding)期(qi)(qi)用(yong)鋼(gang)絲刷刷去上面的積塵(chen)和銹(xiu)皮等(deng),由于(yu)隨著運(yun)轉(zhuan)(zhuan)時刻的加長,這(zhe)些(xie)塵(chen)埃由于(yu)不可(ke)能(neng)(neng)均勻地附著在(zai)葉(xie)(xie)輪(lun)上,而形成葉(xie)(xie)輪(lun)平(ping)衡(heng)(heng)損(sun)壞,以至引起轉(zhuan)(zhuan)子振(zhen)動(dong)。葉(xie)(xie)輪(lun)只(zhi)需進行了(le)修理,就需要對其(qi)再作動(dong)平(ping)衡(heng)(heng)。如有(you)條件(jian),能(neng)(neng)夠運(yun)用(yong)便(bian)攜試動(dong)平(ping)衡(heng)(heng)儀(yi)在(zai)現場進行平(ping)衡(heng)(heng)。在(zai)作動(dong)平(ping)衡(heng)(heng)之前(qian),有(you)必(bi)要查(cha)看(kan)(kan)一切緊定(ding)螺栓是否(fou)上緊。由于(yu)葉(xie)(xie)輪(lun)已經(jing)在(zai)不平(ping)衡(heng)(heng)狀(zhuang)態下運(yun)轉(zhuan)(zhuan)了(le)一段時刻,這(zhe)些(xie)螺栓可(ke)能(neng)(neng)已經(jing)松動(dong)。
3c消(xiao)防排煙風機的軸承部的維修保養
經常查看軸承(cheng)潤滑(hua)油(you)(you)供油(you)(you)情況,假如(ru)箱體(ti)呈現(xian)漏(lou)油(you)(you),能夠把端(duan)蓋(gai)的螺栓擰(ning)緊一(yi)點,這樣(yang)還(huan)不可的話(hua),可能只(zhi)好換用(yong)新(xin)的密封填料(liao)了。軸承(cheng)的潤滑(hua)油(you)(you)正常運(yun)用(yong)時,半年(nian)內(nei)至少應替(ti)(ti)換一(yi)次(ci),運(yun)用(yong)時,大(da)約在運(yun)轉200小時后(hou)進(jin)行,第(di)二次(ci)換油(you)(you)時刻在1~2個(ge)月進(jin)行,今后(hou)應每(mei)周查看潤滑(hua)油(you)(you)一(yi)次(ci),如(ru)潤滑(hua)油(you)(you)沒有(you)(you)變質(zhi),則換油(you)(you)工作可延長至2~4個(ge)月一(yi)次(ci),替(ti)(ti)換時有(you)(you)必要運(yun)用(yong)規(gui)則牌號的潤滑(hua)油(you)(you),并將油(you)(you)箱內(nei)的舊(jiu)油(you)(you)徹底放干(gan)凈且清洗干(gan)凈后(hou)才(cai)干(gan)灌入新(xin)油(you)(you)。
