現階段(duan)是(shi)很多雞(ji)舍都(dou)配備了(le)(le)通(tong)(tong)(tong)風(feng)(feng)(feng)管(guan)，我是(shi)2013年開始用(yong)(yong)(yong)的通(tong)(tong)(tong)風(feng)(feng)(feng)管(guan)，在使(shi)用(yong)(yong)(yong)過程中，曾(ceng)經出(chu)現過很多問(wen)題，現總結一下(xia)(xia)，歡迎拍磚(zhuan)交流。一，通(tong)(tong)(tong)風(feng)(feng)(feng)管(guan)的作用(yong)(yong)(yong)。1降低(di)(di)操(cao)作負壓(ya)。冬季沒(mei)安(an)裝通(tong)(tong)(tong)風(feng)(feng)(feng)管(guan)的雞(ji)舍，使(shi)用(yong)(yong)(yong)小窗通(tong)(tong)(tong)風(feng)(feng)(feng)，尤其是(shi)跨度大(da)的雞(ji)舍為了(le)(le)導風(feng)(feng)(feng)合理安(an)全(quan)，使(shi)用(yong)(yong)(yong)高負壓(ya)通(tong)(tong)(tong)風(feng)(feng)(feng)。而使(shi)用(yong)(yong)(yong)通(tong)(tong)(tong)風(feng)(feng)(feng)管(guan)道，由于進(jin)風(feng)(feng)(feng)在管(guan)道內基本不(bu)擴散，低(di)(di)負壓(ya)下(xia)(xia)都(dou)是(shi)按照風(feng)(feng)(feng)管(guan)方(fang)向(xiang)，依(yi)次從開口處(chu)出(chu)風(feng)(feng)(feng)。2位(wei)(wei)置高，出(chu)風(feng)(feng)(feng)均勻。進(jin)風(feng)(feng)(feng)雖然在管(guan)道內沒(mei)有預(yu)熱，但下(xia)(xia)落位(wei)(wei)置高，向(xiang)下(xia)(xia)擴散時間就是(shi)預(yu)熱過程。3跟風(feng)(feng)(feng)機(ji)配合合理配置，在初始開啟風(feng)(feng)(feng)機(ji)階段(duan)，由于設計問(wen)題導致進(jin)風(feng)(feng)(feng)窗使(shi)用(yong)(yong)(yong)不(bu)安(an)全(quan)，可以利用(yong)(yong)(yong)通(tong)(tong)(tong)風(feng)(feng)(feng)管(guan)過渡。
