在(zai)葉輪(lun)運轉(zhuan)初期(qi)及所(suo)有(you)(you)定期(qi)檢(jian)查(cha)的(de)(de)時(shi)候，只(zhi)要(yao)一有(you)(you)機(ji)會，都必(bi)(bi)須(xu)(xu)檢(jian)查(cha)葉輪(lun)是否(fou)出(chu)現裂紋、磨(mo)損、積塵(chen)等缺陷。只(zhi)要(yao)有(you)(you)可(ke)(ke)能(neng)，都必(bi)(bi)須(xu)(xu)使葉輪(lun)保(bao)持清潔狀(zhuang)態，并定期(qi)用鋼(gang)絲刷刷去(qu)上面的(de)(de)積塵(chen)和(he)銹皮等，因為隨著(zhu)運行(xing)時(shi)間的(de)(de)加長(chang)，這些(xie)灰塵(chen)由于不可(ke)(ke)能(neng)均勻地附著(zhu)在(zai)葉輪(lun)上，而造成葉輪(lun)平(ping)衡(heng)破壞，以(yi)至引起(qi)轉(zhuan)子振動(dong)。葉輪(lun)只(zhi)要(yao)進(jin)行(xing)了修理，就需要(yao)對其再作動(dong)平(ping)衡(heng)。如(ru)有(you)(you)條件，可(ke)(ke)以(yi)使用便攜(xie)試(shi)動(dong)平(ping)衡(heng)儀在(zai)現場進(jin)行(xing)平(ping)衡(heng)。在(zai)作動(dong)平(ping)衡(heng)之前(qian)，必(bi)(bi)須(xu)(xu)檢(jian)查(cha)所(suo)有(you)(you)緊定螺栓(shuan)是否(fou)上緊。因為葉輪(lun)已(yi)經(jing)在(zai)不平(ping)衡(heng)狀(zhuang)態下運行(xing)了一段時(shi)間，這些(xie)螺栓(shuan)可(ke)(ke)能(neng)已(yi)經(jing)松動(dong)。

1、 薄鋼板矩形風管的剛度不夠,表現形式：風管的大邊上下有不同程度的下沉，兩側面小邊稍向外凸出，有明顯的變形。黔江配件對產生的原因分析：① 制作風管的鋼板厚度不符合施工及驗收規范的要求；② 咬口的形式選擇不當；③ 沒有按照《施工及驗收規范》要求，對于邊長≥630 mm或保溫風管≥800 mm，其管長在1 200mm以上，均應采取加固措施。2 、薄鋼板矩形風管扭曲、翹角,表現形式：風管表面不平；對角線不相等；相鄰表面互不垂直；兩相對表面不平行及兩管端平面不平行等。配件產生的(de)(de)原因分析：① 矩形板料(liao)(liao)下料(liao)(liao)后，未對四個角(jiao)進行(xing)嚴(yan)格的(de)(de)角(jiao)方測量；② 風管的(de)(de)大邊或小邊的(de)(de)兩個相對面(mian)的(de)(de)板料(liao)(liao)長度(du)(du)和寬度(du)(du)不相等；③ 風管的(de)(de)四個角(jiao)處(chu)的(de)(de)咬(yao)口(kou)寬度(du)(du)不相等；④ 手工咬(yao)口(kou)合(he)縫受力(li)不均(jun)。

在空(kong)調送(song)風(feng)系(xi)(xi)統(tong)(tong)中(zhong)(zhong)，空(kong)調送(song)風(feng)機(ji)送(song)出(chu)的(de)風(feng)必(bi)須通過主干管分配到(dao)(dao)(dao)支管中(zhong)(zhong)；在排(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)系(xi)(xi)統(tong)(tong)中(zhong)(zhong)，煙(yan)(yan)(yan)(yan)氣(qi)由支管到(dao)(dao)(dao)主干管后，進入(ru)排(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)風(feng)機(ji)排(pai)(pai)(pai)(pai)(pai)出(chu)。當建筑物內發生火(huo)(huo)災時(shi)，在通風(feng)、空(kong)調系(xi)(xi)統(tong)(tong)中(zhong)(zhong)，為了防(fang)止火(huo)(huo)勢通過送(song)風(feng)系(xi)(xi)統(tong)(tong)蔓延，當送(song)風(feng)系(xi)(xi)統(tong)(tong)中(zhong)(zhong)氣(qi)體溫(wen)度達到(dao)(dao)(dao)70℃時(shi)，防(fang)火(huo)(huo)閥(fa)(fa)(fa)機(ji)構(gou)上(shang)熔斷器(qi)動作(zuo)(zuo)，閥(fa)(fa)(fa)門(men)亦(yi)迅速關(guan)閥(fa)(fa)(fa)，切(qie)斷煙(yan)(yan)(yan)(yan)氣(qi)與火(huo)(huo)勢沿風(feng)管蔓延的(de)通路(lu)。同樣，在排(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)系(xi)(xi)統(tong)(tong)中(zhong)(zhong)，發生火(huo)(huo)災時(shi)，排(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)閥(fa)(fa)(fa)開啟，進行排(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)，為了截斷高溫(wen)煙(yan)(yan)(yan)(yan)氣(qi)在排(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)管路(lu)中(zhong)(zhong)流動，防(fang)止火(huo)(huo)勢蔓延到(dao)(dao)(dao)另一(yi)防(fang)火(huo)(huo)分區，當排(pai)(pai)(pai)(pai)(pai)出(chu)的(de)煙(yan)(yan)(yan)(yan)氣(qi)溫(wen)度達到(dao)(dao)(dao)280℃時(shi)，排(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)防(fang)火(huo)(huo)閥(fa)(fa)(fa)、排(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)口上(shang)熔斷器(qi)動作(zuo)(zuo)，閥(fa)(fa)(fa)門(men)必(bi)須自動關(guan)閉，阻(zu)止排(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)。由此可見，防(fang)火(huo)(huo)閥(fa)(fa)(fa)、排(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)閥(fa)(fa)(fa)做到(dao)(dao)(dao)了該通則通，該斷則斷的(de)隔煙(yan)(yan)(yan)(yan)阻(zu)火(huo)(huo)作(zuo)(zuo)用。

現(xian)階段(duan)是(shi)很多雞舍都配備了通(tong)(tong)風(feng)(feng)(feng)(feng)(feng)(feng)管(guan)(guan)(guan)，我是(shi)2013年開始用(yong)(yong)(yong)(yong)的(de)(de)通(tong)(tong)風(feng)(feng)(feng)(feng)(feng)(feng)管(guan)(guan)(guan)，在(zai)使用(yong)(yong)(yong)(yong)過(guo)程中，曾經出現(xian)過(guo)很多問題，現(xian)總(zong)結一下，歡迎拍磚(zhuan)交流。一，通(tong)(tong)風(feng)(feng)(feng)(feng)(feng)(feng)管(guan)(guan)(guan)的(de)(de)作(zuo)用(yong)(yong)(yong)(yong)。1降低(di)操作(zuo)負壓。冬(dong)季沒安裝通(tong)(tong)風(feng)(feng)(feng)(feng)(feng)(feng)管(guan)(guan)(guan)的(de)(de)雞舍，使用(yong)(yong)(yong)(yong)小窗通(tong)(tong)風(feng)(feng)(feng)(feng)(feng)(feng)，尤其是(shi)跨度(du)大(da)的(de)(de)雞舍為了導(dao)風(feng)(feng)(feng)(feng)(feng)(feng)合(he)理安全，使用(yong)(yong)(yong)(yong)高(gao)負壓通(tong)(tong)風(feng)(feng)(feng)(feng)(feng)(feng)。而使用(yong)(yong)(yong)(yong)通(tong)(tong)風(feng)(feng)(feng)(feng)(feng)(feng)管(guan)(guan)(guan)道(dao)(dao)，由于進風(feng)(feng)(feng)(feng)(feng)(feng)在(zai)管(guan)(guan)(guan)道(dao)(dao)內基(ji)本(ben)不(bu)擴(kuo)散，低(di)負壓下都是(shi)按照風(feng)(feng)(feng)(feng)(feng)(feng)管(guan)(guan)(guan)方向，依次從(cong)開口處(chu)出風(feng)(feng)(feng)(feng)(feng)(feng)。2位(wei)置高(gao)，出風(feng)(feng)(feng)(feng)(feng)(feng)均勻(yun)。進風(feng)(feng)(feng)(feng)(feng)(feng)雖然在(zai)管(guan)(guan)(guan)道(dao)(dao)內沒有預熱，但(dan)下落位(wei)置高(gao)，向下擴(kuo)散時間(jian)就是(shi)預熱過(guo)程。3跟風(feng)(feng)(feng)(feng)(feng)(feng)機配合(he)合(he)理配置，在(zai)初始開啟(qi)風(feng)(feng)(feng)(feng)(feng)(feng)機階段(duan)，由于設計問題導(dao)致進風(feng)(feng)(feng)(feng)(feng)(feng)窗使用(yong)(yong)(yong)(yong)不(bu)安全，可以利用(yong)(yong)(yong)(yong)通(tong)(tong)風(feng)(feng)(feng)(feng)(feng)(feng)管(guan)(guan)(guan)過(guo)渡。

1) 送(song)(song)風(feng)(feng)(feng)，包括通氣，如送(song)(song)鮮風(feng)(feng)(feng)和排(pai)(pai)氣，這(zhe)個范圍很廣，如工廠車(che)間，生(sheng)(sheng)產場地空(kong)氣，由于(yu)有(you)害氣體產生(sheng)(sheng)需(xu)要(yao)(yao)排(pai)(pai)出(chu)室外(wai)，又需(xu)要(yao)(yao)把室外(wai)空(kong)氣輸(shu)(shu)送(song)(song)至室內。這(zhe)時(shi)就(jiu)要(yao)(yao)使(shi)用(yong)(yong)流量大而壓力小(xiao)的(de)(de)空(kong)氣輸(shu)(shu)送(song)(song)管(guan)(guan)道，螺(luo)旋風(feng)(feng)(feng)管(guan)(guan)就(jiu)適(shi)用(yong)(yong)，一般情(qing)況下(xia)使(shi)用(yong)(yong)鍍(du)鋅鐵管(guan)(guan)，有(you)腐蝕性及特(te)別潮濕場所使(shi)用(yong)(yong)不銹鋼管(guan)(guan)。2) 送(song)(song)冷風(feng)(feng)(feng)。常見(jian)的(de)(de)是中(zhong)央空(kong)調的(de)(de)管(guan)(guan)道，這(zhe)種管(guan)(guan)道需(xu)要(yao)(yao)加保溫材(cai)料。螺(luo)旋風(feng)(feng)(feng)管(guan)(guan)可(ke)內貼保溫材(cai)料，外(wai)表(biao)看來美觀。3) 排(pai)(pai)油煙。飯店、酒樓、賓館的(de)(de)廚房(fang)均有(you)大量油煙產生(sheng)(sheng)，需(xu)要(yao)(yao)排(pai)(pai)出(chu)，使(shi)用(yong)(yong)圓形的(de)(de)風(feng)(feng)(feng)管(guan)(guan)就(jiu)是油煙囪。在這(zhe)里，螺(luo)旋風(feng)(feng)(feng)管(guan)(guan)該叫做油煙管(guan)(guan)。4) 除塵。有(you)些工廠生(sheng)(sheng)產車(che)間很多塵埃，需(xu)要(yao)(yao)專(zhuan)門的(de)(de)除塵裝置(zhi)，其中(zhong)量較大的(de)(de)管(guan)(guan)道，可(ke)使(shi)用(yong)(yong)螺(luo)旋風(feng)(feng)(feng)管(guan)(guan)。5) 散裝物料輸(shu)(shu)送(song)(song)。有(you)些工廠的(de)(de)生(sheng)(sheng)產過程中(zhong)，需(xu)要(yao)(yao)輸(shu)(shu)送(song)(song)松散的(de)(de)顆粒，特(te)別是比重不大的(de)(de)如發泡塑(su)料粒之類的(de)(de)使(shi)用(yong)(yong)螺(luo)旋風(feng)(feng)(feng)管(guan)(guan)造價低、效果(guo)好。
