江北高品質天園地方管廠家

一、對通風管道制作的要求進行檢查：檢查通風管道穿越防護密閉墻、密閉墻的預埋密閉穿墻短管。通風預埋密閉短管采用厚度不小于3mm鋼板機械卷制成形（其厚度還應根據預埋管管徑大小確定，使預埋管不致變形），高品質天園地方管防爆超壓排氣活門的預埋短管其厚度為6mm，密閉短管中間應設密閉肋，密閉肋厚度為5mm，密閉肋高度為50mm，密閉肋與短管應雙面滿焊、焊縫嚴密。密閉穿墻短管兩端深處墻面的長度應大于100mm，管道內外部除與混凝土接觸部分外均應刷兩道防銹漆。二、對風管連接處制作的要求進行檢查,江北廠家對(dui)染毒(du)區的(de)通風(feng)(feng)管(guan)(guan)道連(lian)(lian)(lian)(lian)接(jie)方法(fa)(fa)(fa)及(ji)(ji)密(mi)(mi)封(feng)進行檢查。如無設計要(yao)求，其風(feng)(feng)管(guan)(guan)厚(hou)度應(ying)采(cai)(cai)用(yong)(yong)大于等于3mm的(de)鋼板焊(han)接(jie)制(zhi)作而成。風(feng)(feng)管(guan)(guan)與風(feng)(feng)管(guan)(guan)連(lian)(lian)(lian)(lian)接(jie)應(ying)采(cai)(cai)用(yong)(yong)焊(han)接(jie)連(lian)(lian)(lian)(lian)接(jie)。通風(feng)(feng)管(guan)(guan)道與密(mi)(mi)閉閥門的(de)連(lian)(lian)(lian)(lian)接(jie)應(ying)采(cai)(cai)用(yong)(yong)帶密(mi)(mi)封(feng)槽的(de)法(fa)(fa)(fa)蘭(lan)(lan)連(lian)(lian)(lian)(lian)接(jie)，其法(fa)(fa)(fa)蘭(lan)(lan)面應(ying)經機(ji)床(chuang)車削加工，保證接(jie)觸應(ying)平整，法(fa)(fa)(fa)蘭(lan)(lan)面有1~2mm深的(de)90°密(mi)(mi)封(feng)槽；風(feng)(feng)管(guan)(guan)與設備連(lian)(lian)(lian)(lian)接(jie)法(fa)(fa)(fa)蘭(lan)(lan)之間應(ying)采(cai)(cai)用(yong)(yong)整體橡(xiang)膠(jiao)法(fa)(fa)(fa)蘭(lan)(lan)墊圈，防爆超壓排氣活(huo)門法(fa)(fa)(fa)蘭(lan)(lan)連(lian)(lian)(lian)(lian)接(jie)填料采(cai)(cai)用(yong)(yong)5mm整張橡(xiang)膠(jiao)墊圈密(mi)(mi)封(feng)（不得有拼(pin)縫），其他染毒(du)區風(feng)(feng)管(guan)(guan)連(lian)(lian)(lian)(lian)接(jie)及(ji)(ji)法(fa)(fa)(fa)蘭(lan)(lan)與設備連(lian)(lian)(lian)(lian)接(jie)采(cai)(cai)用(yong)(yong)4~5mm整張橡(xiang)膠(jiao)墊圈密(mi)(mi)封(feng)（不得有拼(pin)縫），連(lian)(lian)(lian)(lian)接(jie)處不得有漏縫現象。

鑒(jian)于軸(zhou)流(liu)(liu)風(feng)(feng)(feng)機(ji)(ji)有紊流(liu)(liu)區的(de)(de)性(xing)(xing)能特點(dian)(dian)，在(zai)選(xuan)型和(he)使(shi)用(yong)時，需要(yao)注意以下兩點(dian)(dian)：建(jian)議使(shi)用(yong)在(zai)空(kong)曠(kuang)環境(jing)(jing)中,軸(zhou)流(liu)(liu)風(feng)(feng)(feng)機(ji)(ji)的(de)(de)輸(shu)入功(gong)率隨系(xi)統(tong)靜壓(ya)(ya)的(de)(de)增(zeng)(zeng)大(da)(da)(da)而增(zeng)(zeng)大(da)(da)(da)，而在(zai)紊流(liu)(liu)區，輸(shu)入功(gong)率的(de)(de)增(zeng)(zeng)大(da)(da)(da)幅度會更大(da)(da)(da)。因(yin)此(ci)，軸(zhou)流(liu)(liu)風(feng)(feng)(feng)機(ji)(ji)一般多應用(yong)在(zai)有較(jiao)(jiao)大(da)(da)(da)空(kong)曠(kuang)環境(jing)(jing)的(de)(de)場合下，可以使(shi)其(qi)工作在(zai)靜壓(ya)(ya)較(jiao)(jiao)低的(de)(de)環境(jing)(jing)下，降低功(gong)耗，保證(zheng)穩定(ding)性(xing)(xing)和(he)壽命。定(ding)期(qi)(qi)清理(li)風(feng)(feng)(feng)道(dao),當軸(zhou)流(liu)(liu)風(feng)(feng)(feng)機(ji)(ji)應用(yong)在(zai)較(jiao)(jiao)為(wei)封閉的(de)(de)風(feng)(feng)(feng)道(dao)系(xi)統(tong)中時，長期(qi)(qi)運(yun)行(xing)后(hou)風(feng)(feng)(feng)道(dao)中的(de)(de)積灰、垃圾(ji)逐漸(jian)變多，會使(shi)風(feng)(feng)(feng)道(dao)內的(de)(de)靜壓(ya)(ya)逐漸(jian)增(zeng)(zeng)加，使(shi)得風(feng)(feng)(feng)機(ji)(ji)的(de)(de)運(yun)行(xing)工況點(dian)(dian)逐漸(jian)左(zuo)移。這不僅(jin)會降低風(feng)(feng)(feng)機(ji)(ji)性(xing)(xing)能，更重要(yao)的(de)(de)是(shi)會增(zeng)(zeng)加軸(zhou)流(liu)(liu)風(feng)(feng)(feng)機(ji)(ji)進入紊流(liu)(liu)區的(de)(de)風(feng)(feng)(feng)險。因(yin)此(ci)必須要(yao)定(ding)期(qi)(qi)清理(li)風(feng)(feng)(feng)道(dao)，保證(zheng)風(feng)(feng)(feng)機(ji)(ji)工況點(dian)(dian)不產生較(jiao)(jiao)大(da)(da)(da)偏(pian)移。
