云南高品質防火閥廠家

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。云南防火閥對產生的原因分析：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。防火閥產(chan)生的(de)(de)原因分析(xi)：① 矩(ju)形板(ban)料(liao)下料(liao)后，未對(dui)四個角進(jin)行(xing)嚴格的(de)(de)角方測量；② 風管的(de)(de)大邊或小邊的(de)(de)兩(liang)個相對(dui)面(mian)的(de)(de)板(ban)料(liao)長(chang)度和寬度不(bu)(bu)相等；③ 風管的(de)(de)四個角處(chu)的(de)(de)咬(yao)口(kou)寬度不(bu)(bu)相等；④ 手工咬(yao)口(kou)合縫(feng)受力不(bu)(bu)均。

現階段是(shi)很(hen)多雞(ji)舍都配備了通(tong)(tong)風(feng)(feng)(feng)(feng)管(guan)(guan)，我是(shi)2013年開(kai)始用(yong)的通(tong)(tong)風(feng)(feng)(feng)(feng)管(guan)(guan)，在使用(yong)過程中，曾經出現過很(hen)多問(wen)題，現總結一(yi)下(xia)，歡迎(ying)拍磚交流。一(yi)，通(tong)(tong)風(feng)(feng)(feng)(feng)管(guan)(guan)的作(zuo)用(yong)。1降低(di)操作(zuo)負壓。冬季沒(mei)(mei)安(an)裝通(tong)(tong)風(feng)(feng)(feng)(feng)管(guan)(guan)的雞(ji)舍，使用(yong)小窗通(tong)(tong)風(feng)(feng)(feng)(feng)，尤其是(shi)跨度大(da)的雞(ji)舍為了導風(feng)(feng)(feng)(feng)合理(li)安(an)全，使用(yong)高負壓通(tong)(tong)風(feng)(feng)(feng)(feng)。而使用(yong)通(tong)(tong)風(feng)(feng)(feng)(feng)管(guan)(guan)道，由于進(jin)(jin)風(feng)(feng)(feng)(feng)在管(guan)(guan)道內基本不(bu)擴(kuo)散(san)，低(di)負壓下(xia)都是(shi)按照(zhao)風(feng)(feng)(feng)(feng)管(guan)(guan)方向(xiang)，依次從開(kai)口處出風(feng)(feng)(feng)(feng)。2位置(zhi)高，出風(feng)(feng)(feng)(feng)均勻。進(jin)(jin)風(feng)(feng)(feng)(feng)雖然在管(guan)(guan)道內沒(mei)(mei)有預熱，但(dan)下(xia)落(luo)位置(zhi)高，向(xiang)下(xia)擴(kuo)散(san)時間就是(shi)預熱過程。3跟風(feng)(feng)(feng)(feng)機(ji)配合合理(li)配置(zhi)，在初始開(kai)啟風(feng)(feng)(feng)(feng)機(ji)階段，由于設(she)計問(wen)題導致進(jin)(jin)風(feng)(feng)(feng)(feng)窗使用(yong)不(bu)安(an)全，可以利(li)用(yong)通(tong)(tong)風(feng)(feng)(feng)(feng)管(guan)(guan)過渡。

鑒于(yu)軸(zhou)流(liu)風(feng)(feng)(feng)機(ji)有(you)紊(wen)(wen)流(liu)區的(de)(de)(de)(de)性(xing)(xing)能(neng)特點(dian)，在(zai)選型和使(shi)(shi)用時(shi)，需要(yao)注意以下(xia)兩點(dian)：建議使(shi)(shi)用在(zai)空(kong)(kong)曠環境中,軸(zhou)流(liu)風(feng)(feng)(feng)機(ji)的(de)(de)(de)(de)輸(shu)入功(gong)率隨系統靜(jing)壓(ya)的(de)(de)(de)(de)增(zeng)(zeng)(zeng)大(da)(da)而(er)增(zeng)(zeng)(zeng)大(da)(da)，而(er)在(zai)紊(wen)(wen)流(liu)區，輸(shu)入功(gong)率的(de)(de)(de)(de)增(zeng)(zeng)(zeng)大(da)(da)幅度會(hui)(hui)更大(da)(da)。因(yin)此，軸(zhou)流(liu)風(feng)(feng)(feng)機(ji)一般多應用在(zai)有(you)較(jiao)大(da)(da)空(kong)(kong)曠環境的(de)(de)(de)(de)場(chang)合(he)下(xia)，可以使(shi)(shi)其工作(zuo)在(zai)靜(jing)壓(ya)較(jiao)低的(de)(de)(de)(de)環境下(xia)，降低功(gong)耗，保證穩(wen)定(ding)性(xing)(xing)和壽命。定(ding)期清理風(feng)(feng)(feng)道(dao),當軸(zhou)流(liu)風(feng)(feng)(feng)機(ji)應用在(zai)較(jiao)為封閉的(de)(de)(de)(de)風(feng)(feng)(feng)道(dao)系統中時(shi)，長期運(yun)行后(hou)風(feng)(feng)(feng)道(dao)中的(de)(de)(de)(de)積灰、垃圾逐(zhu)漸變(bian)多，會(hui)(hui)使(shi)(shi)風(feng)(feng)(feng)道(dao)內的(de)(de)(de)(de)靜(jing)壓(ya)逐(zhu)漸增(zeng)(zeng)(zeng)加(jia)，使(shi)(shi)得風(feng)(feng)(feng)機(ji)的(de)(de)(de)(de)運(yun)行工況點(dian)逐(zhu)漸左(zuo)移。這不僅會(hui)(hui)降低風(feng)(feng)(feng)機(ji)性(xing)(xing)能(neng)，更重(zhong)要(yao)的(de)(de)(de)(de)是會(hui)(hui)增(zeng)(zeng)(zeng)加(jia)軸(zhou)流(liu)風(feng)(feng)(feng)機(ji)進入紊(wen)(wen)流(liu)區的(de)(de)(de)(de)風(feng)(feng)(feng)險。因(yin)此必須要(yao)定(ding)期清理風(feng)(feng)(feng)道(dao)，保證風(feng)(feng)(feng)機(ji)工況點(dian)不產生較(jiao)大(da)(da)偏移。
