畢節高品質防火閥批發

現(xian)階段是(shi)(shi)很(hen)(hen)多雞(ji)(ji)舍(she)都配備了(le)通(tong)(tong)風(feng)(feng)(feng)(feng)管(guan)，我是(shi)(shi)2013年(nian)開(kai)始用(yong)(yong)(yong)的通(tong)(tong)風(feng)(feng)(feng)(feng)管(guan)，在(zai)使用(yong)(yong)(yong)過(guo)(guo)程(cheng)(cheng)中，曾經出(chu)現(xian)過(guo)(guo)很(hen)(hen)多問題，現(xian)總結一下(xia)，歡迎拍磚交流。一，通(tong)(tong)風(feng)(feng)(feng)(feng)管(guan)的作用(yong)(yong)(yong)。1降(jiang)低操作負壓(ya)(ya)。冬(dong)季沒安裝通(tong)(tong)風(feng)(feng)(feng)(feng)管(guan)的雞(ji)(ji)舍(she)，使用(yong)(yong)(yong)小(xiao)窗通(tong)(tong)風(feng)(feng)(feng)(feng)，尤其是(shi)(shi)跨度大的雞(ji)(ji)舍(she)為(wei)了(le)導風(feng)(feng)(feng)(feng)合理安全，使用(yong)(yong)(yong)高負壓(ya)(ya)通(tong)(tong)風(feng)(feng)(feng)(feng)。而(er)使用(yong)(yong)(yong)通(tong)(tong)風(feng)(feng)(feng)(feng)管(guan)道，由于進(jin)風(feng)(feng)(feng)(feng)在(zai)管(guan)道內(nei)基(ji)本不擴(kuo)散，低負壓(ya)(ya)下(xia)都是(shi)(shi)按(an)照風(feng)(feng)(feng)(feng)管(guan)方向，依次從開(kai)口處出(chu)風(feng)(feng)(feng)(feng)。2位置高，出(chu)風(feng)(feng)(feng)(feng)均勻(yun)。進(jin)風(feng)(feng)(feng)(feng)雖然在(zai)管(guan)道內(nei)沒有(you)預熱(re)，但下(xia)落位置高，向下(xia)擴(kuo)散時間就是(shi)(shi)預熱(re)過(guo)(guo)程(cheng)(cheng)。3跟風(feng)(feng)(feng)(feng)機(ji)配合合理配置，在(zai)初始開(kai)啟風(feng)(feng)(feng)(feng)機(ji)階段，由于設計問題導致進(jin)風(feng)(feng)(feng)(feng)窗使用(yong)(yong)(yong)不安全，可以利用(yong)(yong)(yong)通(tong)(tong)風(feng)(feng)(feng)(feng)管(guan)過(guo)(guo)渡。

在葉輪運轉初期及所有定期檢查的時候，只要一有機會，都必須檢查葉輪是否出現裂紋、磨損、積塵等缺陷。只要有可能，都必須使葉輪保持清潔狀態，并定期用鋼絲刷刷去上面的積塵和銹皮等，因為防火閥隨著運行時間的加長，這些灰塵由于不可能均勻地附著在葉輪上，而造成葉輪平衡破壞，以至引起轉子振動。葉輪只要進行了修理，就需要對其再作動平衡。如有條件，可以使用便攜試動平衡儀在現場進行平衡。在作動平衡之前，防火閥批發必須檢(jian)查所有(you)緊定螺栓是(shi)否上緊。因(yin)為葉(xie)輪已經在不平衡(heng)狀(zhuang)態(tai)下運行了一段時間，這些螺栓可能已經松動。
