通風管道好的消聲器的安裝步驟:1.風管組裝:當風管較消聲器安裝短時,可(ke)(ke)一(yi)(yi)次在地(di)面(mian)組(zu)裝(zhuang)(zhuang)(zhuang)而成(cheng),當(dang)風(feng)(feng)(feng)管(guan)(guan)(guan)較(jiao)(jiao)長(chang)時,可(ke)(ke)視安裝(zhuang)(zhuang)(zhuang)場(chang)地(di)的(de)(de)(de)情況,在地(di)面(mian)分段(duan)組(zu)裝(zhuang)(zhuang)(zhuang)。組(zu)裝(zhuang)(zhuang)(zhuang)時應(ying)(ying)(ying)盡量(liang)調整風(feng)(feng)(feng)道(dao)(dao)(dao)的(de)(de)(de)中心度(du)和(he)(he)水平度(du),避免風(feng)(feng)(feng)管(guan)(guan)(guan)扭曲或上下起波(bo),左右(you)擺龍(long),每段(duan)風(feng)(feng)(feng)道(dao)(dao)(dao)不宜超過10m.組(zu)裝(zhuang)(zhuang)(zhuang)時,墊片(pian)應(ying)(ying)(ying)墊平,法(fa)(fa)蘭螺栓(shuan)應(ying)(ying)(ying)均(jun)(jun)勻擰(ning)緊,螺母帽(mao)均(jun)(jun)朝向(xiang)同一(yi)(yi)方向(xiang)。2.風(feng)(feng)(feng)管(guan)(guan)(guan)就(jiu)位(wei):風(feng)(feng)(feng)管(guan)(guan)(guan)就(jiu)位(wei)前應(ying)(ying)(ying)檢查全部支(zhi)架的(de)(de)(de)水乎度(du)和(he)(he)標高、檢查支(zhi)架的(de)(de)(de)牢固(gu)(gu)(gu)程度(du),風(feng)(feng)(feng)管(guan)(guan)(guan)就(jiu)位(wei)可(ke)(ke)采(cai)(cai)用(yong)直(zhi)接和(he)(he)吊(diao)(diao)具兩(liang)種方法(fa)(fa)。對風(feng)(feng)(feng)管(guan)(guan)(guan)斷面(mian)較(jiao)(jiao)小,又位(wei)置較(jiao)(jiao)低的(de)(de)(de)可(ke)(ke)采(cai)(cai)用(yong)人工就(jiu)位(wei)方法(fa)(fa),只(zhi)需搭(da)(da)設簡易(yi)腳(jiao)(jiao)手(shou)架即可(ke)(ke)。當(dang)風(feng)(feng)(feng)管(guan)(guan)(guan)斷面(mian)較(jiao)(jiao)大(da)且管(guan)(guan)(guan)段(duan)較(jiao)(jiao)長(chang)時,可(ke)(ke)采(cai)(cai)用(yong)滑輪、倒鏈、大(da)繩(sheng)等(deng)方法(fa)(fa)吊(diao)(diao)裝(zhuang)(zhuang)(zhuang)。為了便于風(feng)(feng)(feng)道(dao)(dao)(dao)就(jiu)位(wei),一(yi)(yi)般多采(cai)(cai)用(yong)將(jiang)風(feng)(feng)(feng)道(dao)(dao)(dao)吊(diao)(diao)在腳(jiao)(jiao)手(shou)架上,然后(hou)再將(jiang)其抬放在風(feng)(feng)(feng)道(dao)(dao)(dao)支(zhi)架上的(de)(de)(de)方法(fa)(fa)。腳(jiao)(jiao)手(shou)架應(ying)(ying)(ying)沿其風(feng)(feng)(feng)道(dao)(dao)(dao)長(chang)度(du)方向(xiang)搭(da)(da)設,高度(du)和(he)(he)位(wei)置應(ying)(ying)(ying)適(shi)合施工操作,吊(diao)(diao)裝(zhuang)(zhuang)(zhuang)順(shun)序應(ying)(ying)(ying)先干(gan)管(guan)(guan)(guan)后(hou)支(zhi)、立管(guan)(guan)(guan),吊(diao)(diao)起時,吊(diao)(diao)點應(ying)(ying)(ying)牢固(gu)(gu)(gu),兩(liang)吊(diao)(diao)點應(ying)(ying)(ying)均(jun)(jun)勻受力。垂直(zhi)風(feng)(feng)(feng)管(guan)(guan)(guan)可(ke)(ke)采(cai)(cai)用(yong)人工和(he)(he)大(da)繩(sheng)輔(fu)助(zhu)就(jiu)位(wei)。調整風(feng)(feng)(feng)管(guan)(guan)(guan)保證垂直(zhi)度(du)要求(qiu)。3.風(feng)(feng)(feng)道(dao)(dao)(dao)調直(zhi):就(jiu)位(wei)在支(zhi)架上的(de)(de)(de)風(feng)(feng)(feng)道(dao)(dao)(dao),應(ying)(ying)(ying)撥正位(wei)置,調整風(feng)(feng)(feng)道(dao)(dao)(dao)橫(heng)平豎直(zhi),然后(hou)再按圖集要求(qiu)固(gu)(gu)(gu)定。
從重慶白鐵加好的消聲器工廠了解到,白鐵皮要比馬口鐵耐用,馬口鐵碰破一點,很快會爛掉;可是白鐵皮即使碰消聲器安裝破(po)一大塊,也不容易被銹(xiu)蝕。這(zhe)是因為鋅(xin)的化學性質(zhi)比鐵(tie)活潑,當外界的空氣和水(shui)份向白鐵(tie)皮“進攻”時,鋅(xin)首先與氧氣化合,而(er)保(bao)護(hu)了(le)鐵(tie)的安(an)全。 金屬鋅(xin)除了(le)用來制造白鐵(tie)皮外,也用來制造干電池的外殼。不過干電池外殼的鋅(xin)是較純(chun)的。此外,鋅(xin)也與銅(tong)制成(cheng)銅(tong)鋅(xin)合金——黃(huang)銅(tong)。
標準直管由流水好的消聲器線上直接壓制成連體法蘭。非標直管、彎頭、三通、四通、配件等下料后,在單機設備上完成消聲器安裝TDF法(fa)(fa)蘭成(cheng)型(xing)。法(fa)(fa)蘭角(jiao)由模具直(zhi)接(jie)(jie)(jie)沖壓成(cheng)型(xing),安裝(zhuang)時卡(ka)在四(si)個角(jiao)即可。法(fa)(fa)蘭間的連(lian)接(jie)(jie)(jie)用(yong)(yong)(yong)法(fa)(fa)蘭卡(ka),由鍍鋅鋼(gang)(gang)板制作,經法(fa)(fa)蘭卡(ka)成(cheng)型(xing)機成(cheng)型(xing)后切割(ge)成(cheng)統一的尺寸(cun)供安裝(zhuang)連(lian)接(jie)(jie)(jie)使(shi)用(yong)(yong)(yong)。TDF共板法(fa)(fa)蘭因(yin)與管道(dao)鋼(gang)(gang)板連(lian)成(cheng)一體,不(bu)必(bi)像(xiang)角(jiao)鋼(gang)(gang)法(fa)(fa)蘭般打孔鉚(liu)接(jie)(jie)(jie),在兩節(jie)管道(dao)的連(lian)接(jie)(jie)(jie)上用(yong)(yong)(yong)專用(yong)(yong)(yong)法(fa)(fa)蘭卡(ka),四(si)角(jiao)加90度法(fa)(fa)蘭角(jiao)后用(yong)(yong)(yong)螺栓連(lian)接(jie)(jie)(jie)。
不銹鋼好的消聲器風管的空氣流動性好,有效通流面積大,由于強度大,因此風管振動引起的低頻噪聲更小,空消聲器安裝氣流動(dong)性能(neng)好(hao),系(xi)統(tong)壓降(jiang)小(xiao),日常運行系(xi)統(tong)耗電(dian)量少。目前(qian)還可以采用(yong)扁(bian)橢圓形風(feng)管(guan)來降(jiang)低風(feng)管(guan)的占用(yong)空間高度,由于風(feng)管(guan)的兩邊是圓形,所以氣流穩定,風(feng)管(guan)的剛性好(hao),外(wai)露安裝美觀性好(hao),是比較(jiao)理想(xiang)的風(feng)管(guan)系(xi)列(lie)。
