風(feng)管系統漏風(feng)量測試方法(fa)

1、漏風量測試裝置應采用經檢驗合格的測量儀(yi)器(qi)，或采用符合現行標準規定的計量元件組成的測量裝置。

2、正壓(ya)(ya)或(huo)負壓(ya)(ya)風(feng)管系統與設備的漏風(feng)量(liang)測試(shi)(shi)，分正壓(ya)(ya)試(shi)(shi)驗(yan)和(he)負壓(ya)(ya)試(shi)(shi)驗(yan)兩(liang)類，可采用正壓(ya)(ya)試(shi)(shi)驗(yan)的測試(shi)(shi)來檢驗(yan)。

3、風管系統漏風量測試可(ke)整體或分段進行。

4、風管(guan)系統漏(lou)風量測試應按下列步驟(zou)進行(xing)：

① 測(ce)試前，被測(ce)風管系統的(de)所有開口處均應(ying)嚴密封閉，不得漏(lou)風。

② 將的漏風量測試裝置(zhi)用軟管與被測風管系(xi)統連(lian)接(jie)。

③開啟漏風量測試裝置(zhi)的(de)電源，調節(jie)變頻器的(de)頻率，使風管系(xi)統內(nei)的(de)靜壓(ya)達到設定值(zhi)后，山西地(di)下通風管道加(jia)工(gong)施工(gong)，測出漏風量測試裝置(zhi)量節(jie)流器的(de)壓(ya)差值(zhi)△P。

④ 測(ce)出(chu)流(liu)量(liang)(liang)節流(liu)器的壓差(cha)值△P后，山西地下通風管(guan)(guan)道生(sheng)產廠家，按公式Q=f(△P)(m3/h)計(ji)算出(chu)流(liu)量(liang)(liang)值，該(gai)流(liu)量(liang)(liang)值Q(m3/h)再除以被(bei)測(ce)風管(guan)(guan)系統的展開面積F(㎡)，即為被(bei)測(ce)風管(guan)(guan)系統在實(shi)驗(yan)壓力下的漏(lou)風量(liang)(liang)QA [m3/(h·㎡)]。

5、當(dang)被(bei)測(ce)(ce)風(feng)管系統(tong)的漏風(feng)量QA [m3/(h·㎡)]超過設(she)計或(huo)本(ben)規(gui)程的規(gui)定時，應查(cha)出(chu)漏風(feng)部位(可用聽、摸、觀察、肥皂水或(huo)煙(yan)氣檢漏)，做好標記;并在修補后重新測(ce)(ce)試，直至(zhi)合格。

為您介(jie)紹通風管(guan)道知識：

通風管道應該(gai)注意(yi)的(de)事項：

1 對(dui)于比較(jiao)復雜的民用建(jian)筑，在(zai)設計(ji)階段，各工種(暖(nuan)通、給(gei)水排水，供(gong)電照明與(yu)建(jian)筑)首先(xian)應協商(shang)好空間分隔，定出每(mei)種管道(dao)的標(biao)高(gao)范(fan)圍。一般情(qing)況下不得(de)越出給(gei)自(zi)己(ji)規定的界(jie)限。遇有個別管段要越界(jie)時應與(yu)通風(feng)管道(dao)其他工程(cheng)協商(shang)。

2 解決各種通(tong)風(feng)(feng)管(guan)(guan)(guan)道(dao)相碰(peng)及協調(diao)的原則(ze)，一般為：“小管(guan)(guan)(guan)讓大管(guan)(guan)(guan)，有壓(ya)讓無(wu)壓(ya)”。例(li)如，自來水(shui)管(guan)(guan)(guan)與(yu)風(feng)(feng)管(guan)(guan)(guan)相撞，山西地下通(tong)風(feng)(feng)管(guan)(guan)(guan)道(dao)，則(ze)應當自來水(shui)管(guan)(guan)(guan)拐彎。冷、熱水(shui)管(guan)(guan)(guan)與(yu)下水(shui)管(guan)(guan)(guan)相碰(peng)，則(ze)應改(gai)變(bian)冷、熱水(shui)管(guan)(guan)(guan)道(dao)。

3 施工(gong)前(qian)應(ying)設備總管的工(gong)程師，將各(ge)工(gong)種(zhong)(zhong)的管線(xian)，單(dan)線(xian)畫在一張(zhang)平面圖上。每種(zhong)(zhong)管道用一種(zhong)(zhong)彩(cai)色筆。在各(ge)交點(dian)處綜合其標高，看是否有矛盾之處，及時發現，將問題解決在安裝之前(qian)。

4 為了減少投資，節省空間(jian)，降(jiang)低(di)層高，有些敷(fu)設無(wu)坡度要求的管道(dao)，可以(yi)穿梁敷(fu)設(如自(zi)來水管道(dao)，消(xiao)防噴灑(sa)干管等)。

不銹鋼風管(guan)安裝有(you)損壞怎么辦?

當風(feng)管(guan)加工出現耐蝕(shi)性差時，通常會在(zai)風(feng)管(guan)表(biao)面(mian)產(chan)生劃傷、擦毛等(deng)缺陷(xian)和(he)焊(han)渣飛濺物(wu)，焊(han)縫表(biao)面(mian)呈現黑色、黃斑、花斑或(huo)局部(bu)腐蝕(shi)。這將影(ying)(ying)(ying)響(xiang)整個通風(feng)系統(tong)(tong)的(de)抗(kang)腐蝕(shi)能力，縮短(duan)其使(shi)用(yong)壽命。與此(ci)同時，共板風(feng)管(guan)由于局部(bu)腐蝕(shi)，影(ying)(ying)(ying)響(xiang)了通風(feng)系統(tong)(tong)的(de)嚴密性，如果輸送的(de)是(shi)有害氣體，氣體通過腐蝕(shi)部(bu)位擴散到環境中，影(ying)(ying)(ying)響(xiang)周圍人(ren)的(de)身體。

不銹(xiu)鋼風(feng)管(guan)(guan)焊接的(de)保溫(wen)工作(zuo)，一般都(dou)用(yong)橡塑保溫(wen)棉比(bi)較(jiao)多。風(feng)管(guan)(guan)加(jia)工廠(chang)也可以用(yong)膠、包扎風(feng)管(guan)(guan)進行(xing)纏繞，起到保溫(wen)作(zuo)用(yong)。與(yu)此同時，可承受較(jiao)大(da)的(de)壓(ya)力，因為(wei)它的(de)制(zhi)作(zuo)，就是(shi)螺旋壓(ya)制(zhi)。此外，也可采用(yong)螺旋形(xing)楞筋(jin)，以增強風(feng)管(guan)(guan)的(de)受壓(ya)能(neng)力。不銹(xiu)鋼板(ban)焊接風(feng)管(guan)(guan)這種風(feng)管(guan)(guan)，其安(an)裝(zhuang)空間，螺旋風(feng)管(guan)(guan)廠(chang)家不需(xu)要很大(da)的(de)，因為(wei)，它只(zhi)需(xu)較(jiao)小的(de)安(an)裝(zhuang)空間。
