廚房排煙管道專業螺旋風管的設計和安裝不合理,往往會造成廚房排煙不通暢,直接影響油煙凈化器的使用,其主要螺旋風管廠家原因(yin)有以(yi)下幾種(zhong): 一(yi)(yi)(yi)(yi)、主(zhu)(zhu)排(pai)(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)管(guan)(guan)(guan)道通風面積不夠

根據工程經驗,排(pai)(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)主(zhu)(zhu)管(guan)(guan)(guan)道內風速(su)不能超過(guo)(guo)15m/s,否則在(zai)(zai)(zai)運行(xing)一(yi)(yi)(yi)(yi)個時(shi)(shi)期以(yi)后(hou)(hou)很(hen)容易(yi)造成(cheng)排(pai)(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)系統不通暢。在(zai)(zai)(zai)油煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)凈(jing)化器(qi)的(de)(de)(de)(de)運行(xing)實踐中(zhong),大部分案例都(dou)是(shi)因(yin)排(pai)(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)管(guan)(guan)(guan)道通風面積不足引(yin)起(qi)的(de)(de)(de)(de)不通暢,管(guan)(guan)(guan)道內氣體的(de)(de)(de)(de)流速(su)都(dou)在(zai)(zai)(zai)15m/s以(yi)上。 二、管(guan)(guan)(guan)道截(jie)(jie)(jie)面積變小 迅(xun)(xun)速(su)排(pai)(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)防(fang)止串味(wei)

三、排(pai)(pai)(pai)(pai)(pai)(pai)管(guan)(guan)(guan)道使(shi)用后(hou)(hou)積聚物(wu)堆(dui)積 迅(xun)(xun)速(su)排(pai)(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)防(fang)止串味(wei)

四(si)、低(di)層(ceng)排(pai)(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)不順暢 不同樓層(ceng)的(de)(de)(de)(de)廚(chu)(chu)(chu)房(fang)(fang)油煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)通過(guo)(guo)同一(yi)(yi)(yi)(yi)主(zhu)(zhu)管(guan)(guan)(guan)道排(pai)(pai)(pai)(pai)(pai)(pai)出(chu),離出(chu)口(kou)近(jin)的(de)(de)(de)(de)樓層(ceng)廚(chu)(chu)(chu)房(fang)(fang)排(pai)(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)效果較(jiao)(jiao)好,而較(jiao)(jiao)低(di)樓層(ceng)的(de)(de)(de)(de)廚(chu)(chu)(chu)房(fang)(fang)排(pai)(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)不通暢。 五、建(jian)議配備(bei)(bei)排(pai)(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)風機(ji)(ji)(ji)(ji) 對于油煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)較(jiao)(jiao)大的(de)(de)(de)(de)廚(chu)(chu)(chu)房(fang)(fang),建(jian)議還配備(bei)(bei)一(yi)(yi)(yi)(yi)個排(pai)(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)風機(ji)(ji)(ji)(ji)。常(chang)用的(de)(de)(de)(de)排(pai)(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)風機(ji)(ji)(ji)(ji)有軸(zhou)流風機(ji)(ji)(ji)(ji)、風機(ji)(ji)(ji)(ji)箱(xiang)和離心風機(ji)(ji)(ji)(ji)3種(zhong)。 軸(zhou)流風機(ji)(ji)(ji)(ji):以(yi)前(qian)應(ying)用較(jiao)(jiao)多,但由于全(quan)壓(ya)小,在(zai)(zai)(zai)安裝(zhuang)油煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)凈(jing)化器(qi)后(hou)(hou)很(hen)少應(ying)用。 風機(ji)(ji)(ji)(ji)箱(xiang):全(quan)壓(ya)中(zhong)等,風量(liang)可以(yi)調(diao)節,且噪聲較(jiao)(jiao)低(di),常(chang)在(zai)(zai)(zai)集煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)罩距油煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)排(pai)(pai)(pai)(pai)(pai)(pai)放口(kou)距離中(zhong)等的(de)(de)(de)(de)廚(chu)(chu)(chu)房(fang)(fang)排(pai)(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)系統中(zhong)選用。 離心風機(ji)(ji)(ji)(ji):全(quan)壓(ya)和風量(liang)都(dou)可以(yi)調(diao)節,但由于噪聲較(jiao)(jiao)大,常(chang)需(xu)要(yao)做降噪處理。當廚(chu)(chu)(chu)房(fang)(fang)位于建(jian)筑(zhu)物(wu)的(de)(de)(de)(de)底部時(shi)(shi)其排(pai)(pai)(pai)(pai)(pai)(pai)風機(ji)(ji)(ji)(ji)宜安放在(zai)(zai)(zai)屋(wu)頂,一(yi)(yi)(yi)(yi)般選擇離心風機(ji)(ji)(ji)(ji)。
說到白鐵大家可能都非常專業螺旋風管模糊,是不是白色的鐵就叫白鐵?其實白鐵就是大家都非常熟悉的鍍鋅鐵。鐵是我們螺旋風管生活中使(shi)用(yong)廣(guang)泛的(de)(de)金(jin)屬(shu)材料,在(zai)任何地方(fang)都會有鐵(tie)的(de)(de)使(shi)用(yong)。人們之(zhi)所以(yi)要對鐵(tie)進行(xing)鍍鋅(xin),是(shi)因為鐵(tie)在(zai)代大(da)氣中非常(chang)活躍(yue),只要本質比較活躍(yue)的(de)(de)金(jin)屬(shu)材料都很容易和氧氣產生化(hua)學反應,但是(shi)經過鍍鋅(xin)之(zhi)后就能夠起到保護作用(yong),這樣(yang)就不會發生氧化(hua)現(xian)象發生。
白鐵風管專業螺旋風管具有以下特點: 1、外觀光滑,無鋅螺旋風管廠家瘤、毛(mao)刺,呈銀白色; 2、安裝方(fang)便,連(lian)接點少; 3、通風(feng)阻力小(xiao)(xiao),通風(feng)噪聲小(xiao)(xiao); 4、強(qiang)度與剛性(xing)均好(hao); 5、厚度均為(wei)可(ke)控,在6-108μm之(zhi)內任意選擇; 6、無氫脆(cui)、無溫度危害(hai),可(ke)保證材(cai)料力學性(xing)能(neng)不(bu)變; 7、可(ke)代替(ti)部分需熱鍍(du)鋅(xin)的工藝; 8、耐腐(fu)蝕(shi)性(xing)好(hao),中性(xing)鹽霧試(shi)驗達240小(xiao)(xiao)時; 9、采用(yong)熱鍍(du)鋅(xin)方(fang)法完成,適用(yong)于各(ge)種(zhong)強(qiang)酸、堿(jian)霧氣(qi)等(deng)強(qiang)腐(fu)蝕(shi)環境中; 10、可(ke)根據(ju)客戶要(yao)求,專門設計、定做各(ge)種(zhong)規格風(feng)管。
共板法蘭風管的制作步驟: (1)下料; (2)打孔; (3)焊接; (4)鉆螺孔; (5)上漆防腐。 以上工藝制作的專業螺旋風管法蘭盤仍然存在著互換性差的問題,現象有:法蘭表面不平整,矩形法蘭旋轉180度后,與同螺旋風管廠家規格的(de)法(fa)蘭螺孔不重(zhong)(zhong)合,內邊尺寸或兩對角線的(de)尺寸不相等(deng)超(chao)過允許的(de)偏(pian)差等(deng),影響風(feng)管(guan)部件在施工(gong)(gong)現場的(de)正常組裝。重(zhong)(zhong)慶通風(feng)管(guan)道偏(pian)差小(xiao)的(de)造成(cheng)在安裝過程中的(de)不必要(yao)的(de)修改(gai)、打(da)孔;偏(pian)差過大(da)造成(cheng)返工(gong)(gong)和浪費。
共板法蘭風專業螺旋風管管加工后的安裝要求: 1、按照重慶共板法專業螺旋風管蘭(lan)風(feng)管(guan)的中(zhong)心線(xian)找出吊(diao)桿敷設(she)位置,單吊(diao)桿在(zai)風(feng)管(guan)的中(zhong)心線(xian)上(shang),雙吊(diao)桿可(ke)以按托盤的螺孔間距或風(feng)管(guan)的中(zhong)心線(xian)對稱安(an)(an)裝。 2、吊(diao)桿根(gen)據(ju)吊(diao)件形(xing)式,可(ke)以焊在(zai)吊(diao)件上(shang),也可(ke)掛在(zai)吊(diao)件上(shang),焊接(jie)后(hou)應(ying)涂(tu)防銹漆。當風(feng)管(guan)較長需要安(an)(an)裝一排支架時,可(ke)先把兩端(duan)安(an)(an)好,然(ran)后(hou)以兩端(duan)的支架為(wei)基(ji)準,用拉線(xian)法找出中(zhong)間支架的標高進行(xing)安(an)(an)裝。
從重慶白鐵加專業螺旋風管工廠了解到,白鐵皮要比馬口鐵耐用,馬口鐵碰破一點,很快會爛掉;可是白鐵皮即使碰螺旋風管廠家破一大(da)塊,也不容易(yi)被銹蝕。這是因為鋅(xin)的(de)化學性質比(bi)鐵(tie)活(huo)潑,當外(wai)界的(de)空氣和水份向(xiang)白(bai)鐵(tie)皮“進攻”時(shi),鋅(xin)首先與氧氣化合(he),而保護了鐵(tie)的(de)安全。 金屬(shu)鋅(xin)除了用來制(zhi)造(zao)白(bai)鐵(tie)皮外(wai),也用來制(zhi)造(zao)干電池(chi)(chi)的(de)外(wai)殼。不過干電池(chi)(chi)外(wai)殼的(de)鋅(xin)是較(jiao)純的(de)。此外(wai),鋅(xin)也與銅(tong)制(zhi)成銅(tong)鋅(xin)合(he)金——黃銅(tong)。
