萬州值得信賴的防火閥批發

現(xian)階段(duan)是(shi)很多(duo)雞舍(she)都(dou)配(pei)備(bei)了(le)通風(feng)(feng)管(guan)(guan)(guan)，我(wo)是(shi)2013年(nian)開始用的(de)通風(feng)(feng)管(guan)(guan)(guan)，在(zai)(zai)使(shi)(shi)用過程中，曾經(jing)出現(xian)過很多(duo)問(wen)題(ti)，現(xian)總結一下(xia)(xia)，歡迎(ying)拍磚交流。一，通風(feng)(feng)管(guan)(guan)(guan)的(de)作(zuo)(zuo)用。1降低操(cao)作(zuo)(zuo)負(fu)壓(ya)。冬季沒安裝通風(feng)(feng)管(guan)(guan)(guan)的(de)雞舍(she)，使(shi)(shi)用小窗通風(feng)(feng)，尤(you)其是(shi)跨(kua)度大的(de)雞舍(she)為了(le)導風(feng)(feng)合(he)理安全，使(shi)(shi)用高負(fu)壓(ya)通風(feng)(feng)。而使(shi)(shi)用通風(feng)(feng)管(guan)(guan)(guan)道，由于進(jin)風(feng)(feng)在(zai)(zai)管(guan)(guan)(guan)道內基本不(bu)(bu)擴散(san)，低負(fu)壓(ya)下(xia)(xia)都(dou)是(shi)按(an)照風(feng)(feng)管(guan)(guan)(guan)方向(xiang)(xiang)，依(yi)次從開口處出風(feng)(feng)。2位(wei)置高，出風(feng)(feng)均(jun)勻。進(jin)風(feng)(feng)雖然在(zai)(zai)管(guan)(guan)(guan)道內沒有預熱，但(dan)下(xia)(xia)落位(wei)置高，向(xiang)(xiang)下(xia)(xia)擴散(san)時間就是(shi)預熱過程。3跟風(feng)(feng)機配(pei)合(he)合(he)理配(pei)置，在(zai)(zai)初始開啟風(feng)(feng)機階段(duan)，由于設計問(wen)題(ti)導致進(jin)風(feng)(feng)窗使(shi)(shi)用不(bu)(bu)安全，可以(yi)利用通風(feng)(feng)管(guan)(guan)(guan)過渡。
