玻璃鋼冷卻塔符號

玻(bo)璃鋼冷(leng)(leng)(leng)卻(que)塔(ta)各系列均(jun)由(you)用符號編制(zhi)的(de)(de)(de)型號，如(ru)5NB-100、5HB-200、10BNB-300等(deng)，以(yi)10BNB-300為例，其(qi)符號的(de)(de)(de)意義為：10—冷(leng)(leng)(leng)卻(que)水(shui)(shui)溫(wen)差為Δt=10℃；B—玻(bo)璃鋼；N—逆流式(shi)(shi)；B—標準(zhun)型；300—冷(leng)(leng)(leng)卻(que)水(shui)(shui)量為300m3h。各冷(leng)(leng)(leng)卻(que)塔(ta)生產廠或廠家所(suo)用的(de)(de)(de)符號和符號順序是有(you)(you)所(suo)不同的(de)(de)(de)，有(you)(you)的(de)(de)(de)用漢語拼(pin)(pin)音(yin)(yin)的(de)(de)(de)第(di)一個(ge)字(zi)母(mu)，如(ru)逆的(de)(de)(de)拼(pin)(pin)音(yin)(yin)為ni，故用表(biao)示(shi)逆流式(shi)(shi)；有(you)(you)的(de)(de)(de)用英語中拼(pin)(pin)音(yin)(yin)的(de)(de)(de)第(di)一個(ge)字(zi)母(mu)。我國目前用的(de)(de)(de)符號基本上均(jun)為漢語拼(pin)(pin)音(yin)(yin)的(de)(de)(de)第(di)一個(ge)字(zi)母(mu)。可能遇到的(de)(de)(de)符號說明(ming)見下圖。有(you)(you)時符號中還(huan)可能出(chu)現T—表(biao)示(shi)超(chao)低噪聲塔(ta)等(deng)。
