有關排煙風機的控制可靠性問題


      排煙系統是重要的火災救災設備系統。其可靠性是非常值得重視的。因而針對排煙風機的(de)控(kong)(kong)(kong)制(zhi)(zhi),有很多的(de)要(yao)(yao)求(qiu)(qiu)。在(zai)自(zi)動(dong)(dong)(dong)控(kong)(kong)(kong)制(zhi)(zhi)、就(jiu)地手(shou)(shou)動(dong)(dong)(dong)控(kong)(kong)(kong)制(zhi)(zhi)的(de)基礎上還要(yao)(yao)求(qiu)(qiu)可在(zai)消(xiao)防控(kong)(kong)(kong)制(zhi)(zhi)室遠(yuan)程(cheng)手(shou)(shou)動(dong)(dong)(dong)應急控(kong)(kong)(kong)制(zhi)(zhi)。有時(shi)還有提(ti)出常閉排煙(yan)口手(shou)(shou)動(dong)(dong)(dong)打開(kai)時(shi)硬線聯(lian)動(dong)(dong)(dong)排煙(yan)風(feng)機直(zhi)接啟(qi)動(dong)(dong)(dong)的(de)要(yao)(yao)求(qiu)(qiu)。同(tong)時(shi)相關規范(fan)不僅對(dui)排煙(yan)風(feng)機提(ti)出各(ge)種啟(qi)動(dong)(dong)(dong)的(de)要(yao)(yao)求(qiu)(qiu),也(ye)提(ti)及(ji)了(le)停止的(de)要(yao)(yao)求(qiu)(qiu),包括應急控(kong)(kong)(kong)制(zhi)(zhi)的(de)遠(yuan)程(cheng)硬線控(kong)(kong)(kong)制(zhi)(zhi)停止要(yao)(yao)求(qiu)(qiu)。從最簡(jian)單(dan)的(de)手(shou)(shou)動(dong)(dong)(dong)啟(qi)停控(kong)(kong)(kong)制(zhi)(zhi),到(dao)自(zi)動(dong)(dong)(dong)控(kong)(kong)(kong)制(zhi)(zhi),再到(dao)單(dan)點或多點聯(lian)動(dong)(dong)(dong)、聯(lian)鎖自(zi)動(dong)(dong)(dong)控(kong)(kong)(kong)制(zhi)(zhi),平行或順序(xu)控(kong)(kong)(kong)制(zhi)(zhi)層(ceng)次(ci)的(de)增加(jia),改(gai)變(bian)著二次(ci)控(kong)(kong)(kong)制(zhi)(zhi)電路(lu)的(de)繁簡(jian)程(cheng)度,這(zhe)對(dui)可靠性(xing)也(ye)存在(zai)一定影響。 

    在實際工程(cheng)中,關于硬線(xian)(xian)控制的要求,也出現(xian)了一些討論。即硬線(xian)(xian)控制應(ying)該覆蓋多(duo)大范圍?是硬線(xian)(xian)控制越多(duo)越可靠嗎?

    控(kong)制功能的可(ke)靠(kao)實現,首先有賴于主工(gong)藝的控(kong)制簡化及(ji)可(ke)靠(kao)性設(she)(she)計。其(qi)次,控(kong)制方(fang)式及(ji)適(shi)用范圍,應從可(ke)靠(kao)性角(jiao)度出發,研(yan)究設(she)(she)備(bei)運(yun)行特點和工(gong)藝目標(biao),本著簡化、優化的原則做出選擇。 

    同時(shi),不(bu)同控制方式之間盡量(liang)采用并行(xing)方式,避免相(xiang)互影響(xiang);盡量(liang)避免局部交叉(cha)串聯的(de)設計。

    硬線控(kong)(kong)制(zhi)(zhi)(zhi)的使用范圍(wei)應適當控(kong)(kong)制(zhi)(zhi)(zhi)。對(dui)于較(jiao)為復雜的控(kong)(kong)制(zhi)(zhi)(zhi)系(xi)統,應更為重(zhong)視在自(zi)動控(kong)(kong)制(zhi)(zhi)(zhi)系(xi)統設備、元件、網絡的采(cai)(cai)購、施工、調(diao)試、維(wei)護等方面采(cai)(cai)取有(you)效措施,保證自(zi)動控(kong)(kong)制(zhi)(zhi)(zhi)系(xi)統可靠(kao)性。因為自(zi)動控(kong)(kong)制(zhi)(zhi)(zhi)系(xi)統的可靠(kao)性是具有(you)全局(ju)性影響的,甚(shen)至是不容有(you)失的。
