壓力控制器動作到啟動泵間的時(shi)間要求

在(zai)消防工程(cheng)給(gei)水系統(tong)中，從水源放(fang)水到報(bao)警閥開(kai)啟，壓力(li)控制器動作(zuo)啟泵(beng)的時間要求是什(shen)么，我(wo)們可(ke)以討論一下。

因(yin)(yin)為現場已(yi)經有延時(shi)(shi)繼電(dian)(dian)器(qi)(qi)(qi)，因(yin)(yin)高層(ceng)頂部末端放(fang)水有水箱但無穩(wen)壓泵時(shi)(shi)，報警(jing)閥(fa)開(kai)啟壓力開(kai)關(guan)動作(zuo)較(jiao)慢，是不是頂層(ceng)延時(shi)(shi)繼電(dian)(dian)器(qi)(qi)(qi)延遲時(shi)(shi)間(jian)調短，以使總時(shi)(shi)間(jian)不致過(guo)長。由于有相關(guan)設備設計規定，安裝(zhuang)延時(shi)(shi)繼電(dian)(dian)器(qi)(qi)(qi)的(de)濕式報警(jing)閥(fa)和不安裝(zhuang)延時(shi)(shi)繼電(dian)(dian)器(qi)(qi)(qi)的(de)濕式報警(jing)閥(fa)是不同的(de)設定規則。

自(zi)系(xi)統(tong)側放(fang)水(shui)至報(bao)(bao)警(jing)(jing)裝(zhuang)(zhuang)(zhuang)置連(lian)(lian)續報(bao)(bao)警(jing)(jing)所需時(shi)間應符合(he)規定。安裝(zhuang)(zhuang)(zhuang)延時(shi)繼(ji)電(dian)(dian)器(qi)的(de)濕式(shi)報(bao)(bao)警(jing)(jing)閥(fa)(fa)延遲時(shi)間，從系(xi)統(tong)側放(fang)水(shui)開始，到(dao)延時(shi)繼(ji)電(dian)(dian)器(qi)頂部壓力為(wei)(wei)(wei)(wei)0.5公斤力時(shi)為(wei)(wei)(wei)(wei)止計算。不(bu)安裝(zhuang)(zhuang)(zhuang)延時(shi)繼(ji)電(dian)(dian)器(qi)的(de)濕式(shi)報(bao)(bao)警(jing)(jing)閥(fa)(fa)，系(xi)統(tong)側放(fang)水(shui)后15s內報(bao)(bao)警(jing)(jing)裝(zhuang)(zhuang)(zhuang)置應開始連(lian)(lian)續報(bao)(bao)警(jing)(jing)。安裝(zhuang)(zhuang)(zhuang)延時(shi)繼(ji)電(dian)(dian)器(qi)的(de)濕式(shi)報(bao)(bao)警(jing)(jing)閥(fa)(fa)，系(xi)統(tong)側放(fang)水(shui)后5~90s內報(bao)(bao)警(jing)(jing)裝(zhuang)(zhuang)(zhuang)置應開始連(lian)(lian)續報(bao)(bao)警(jing)(jing)。因此(ci)，安裝(zhuang)(zhuang)(zhuang)延時(shi)繼(ji)電(dian)(dian)器(qi)的(de)濕式(shi)報(bao)(bao)警(jing)(jing)閥(fa)(fa)系(xi)統(tong)，系(xi)統(tong)側放(fang)水(shui)后報(bao)(bao)警(jing)(jing)裝(zhuang)(zhuang)(zhuang)置開始連(lian)(lian)續報(bao)(bao)警(jing)(jing)的(de)時(shi)間應為(wei)(wei)(wei)(wei)15+5=20到(dao)90秒(miao)。所以施(shi)工驗收(shou)應以90秒(miao)為(wei)(wei)(wei)(wei)限(xian)。

以上是消防工程給(gei)水系統中(zhong)自噴末(mo)端常見的(de)問(wen)題(ti)，壓力控(kong)制(zhi)器動作到啟動泵間的(de)時間都有著相關(guan)規定，壓力控(kong)制(zhi)器的(de)時間控(kong)制(zhi)根據具體需(xu)要選擇不同的(de)設計方案(an)。
