干粉滅火器廠家批發

1.生活、消防(fang)共用給水系(xi)統

管網內的水經常流動，水質不易變壞，在投資上較經常，也便于干粉滅火器廠家日常檢查和維護，消防給水較安全可靠。共用給水系統在生活用水量達到最大小時用水量時，應仍能保證全部消防用水量。

2.生產、消防共用給水系統

應考慮當(dang)生產用(yong)水(shui)量為最大小時用(yong)水(shui)量時，消防用(yong)水(shui)量能全(quan)部保(bao)證；當(dang)消防用(yong)水(shui)時，不致造成生產事故；當(dang)生產設備檢修(xiu)時，不致造成消防用(yong)水(shui)中斷。

當采用生活(huo)、消防共用給(gei)水(shui)系統時(shi)，獨(du)立(li)的生產給(gei)水(shui)系統可作為(wei)消防第二水(shui)源，但轉換閥不得多于兩個，閥門開啟時(shi)間不得超過5min。

由于(yu)(yu)生(sheng)產用(yong)(yong)(yong)(yong)(yong)水(shui)和消(xiao)(xiao)(xiao)防用(yong)(yong)(yong)(yong)(yong)水(shui)兩者水(shui)壓要求(qiu)相差(cha)較大，在消(xiao)(xiao)(xiao)防用(yong)(yong)(yong)(yong)(yong)水(shui)時往往影(ying)響生(sheng)產用(yong)(yong)(yong)(yong)(yong)水(shui)；或由于(yu)(yu)水(shui)壓提高后生(sheng)產用(yong)(yong)(yong)(yong)(yong)水(shui)量(liang)也隨之(zhi)遞(di)增而影(ying)響消(xiao)(xiao)(xiao)防用(yong)(yong)(yong)(yong)(yong)水(shui)量(liang)；某(mou)些工(gong)業企業的生(sheng)產用(yong)(yong)(yong)(yong)(yong)水(shui)，其(qi)水(shui)質(zhi)有特殊(shu)要求(qiu)；或生(sheng)產用(yong)(yong)(yong)(yong)(yong)水(shui)易被易然、可燃液體污染而不能(neng)用(yong)(yong)(yong)(yong)(yong)于(yu)(yu)消(xiao)(xiao)(xiao)防。因此(ci)，生(sheng)產用(yong)(yong)(yong)(yong)(yong)水(shui)與消(xiao)(xiao)(xiao)防用(yong)(yong)(yong)(yong)(yong)水(shui)共同系(xi)統較少采用(yong)(yong)(yong)(yong)(yong)。

3.生活、生產、消防共用(yong)給水系統

大中型城(cheng)鎮的給水系統(tong)均為生活、生產、消防共(gong)用(yong)給水系統(tong)。可節(jie)約投資(zi)、經濟合(he)理(li)、也較安全可靠。

要求當生活、消防為(wei)最(zui)大(da)小時用水量(liang)時，仍應保證按設計(ji)秒流量(liang)計(ji)算的室內、外(wai)消防用水量(liang)。

4.專用消防給水系統

消(xiao)防(fang)(fang)用(yong)(yong)(yong)水(shui)量占有極(ji)大比重時(shi)，或(huo)生(sheng)活、生(sheng)產(chan)、消(xiao)防(fang)(fang)用(yong)(yong)(yong)水(shui)合并在技術(shu)上不可(ke)(ke)能(neng)(neng)時(shi)，或(huo)生(sheng)產(chan)用(yong)(yong)(yong)水(shui)可(ke)(ke)能(neng)(neng)被易燃(ran)、可(ke)(ke)燃(ran)液體污(wu)染時(shi)，可(ke)(ke)采用(yong)(yong)(yong)專用(yong)(yong)(yong)、即獨立的消(xiao)防(fang)(fang)給水(shui)系(xi)統，如水(shui)噴霧消(xiao)防(fang)(fang)系(xi)統即為專用(yong)(yong)(yong)消(xiao)防(fang)(fang)給水(shui)系(xi)統。
