Amathangi Amanzi E-Sprinkler Yomlilo: Ukuhlanganisa Kohlelo Nokulinganisa Kokugcinwa
Ithangi lamanzi lesifutho somlilo iyisitoreji esigciniwe esivumela uhlelo lwesifutho ukuthi luhlale isikhathi esidingekayo, futhi ukuxhumana kwethangi, ukudonsa kanye nomthamo ogciniwe kuyashintsha ngohlobo lwesistimu — amasistimu amanzi kanye nawomile adonsa ethangini elifanayo nge-NFPA 20, kuyilapho i-pre-action ne-deluge zengeza ukutholwa kanye nesidingo esiphezulu okumele isitoreji esigciniwe sibhekane naso.
Uhlelo lokufafaza luncike kuphela emanzini angemuva kwalo. Ithangi lamanzi lokufafaza umlilo iyisitoreji esigciniwe esihambisa uhlelo phakathi nesikhathi esidingekayo lapho ukuhlinzekwa kukamasipala kungekho, kukhawulelwe, noma kudingeka ukuthi kuzimele. Le ndatshana ihlanganisa indlela amathangi ahlangana ngayo nezinhlelo zokufafaza — ezimanzi, ezomile, ezisebenza ngaphambi komlilo kanye neziwukukhukhula — nokuthi isitoreji silinganiswa kanjani kulezo zinhlobo zezinhlelo ngaphansi kwe-NFPA 13, NFPA 14, NFPA 20 kanye ne-NFPA 22. Kuwumhlahlandlela jikelele wokuhlanganiswa kwezinhlelo zokufafaza, hhayi oqondene ngqo nesikhungo sedatha.
Le ndatshana ibhalwe njengesiqondiso sobunjiniyela, hhayi njengokucaphuna kwephrojekthi. Izibalo zesitoreji esigciniwe ezingezansi ziyizibonelo ukukhombisa ukuthi isidingo siyahluka kanjani ngohlobo lwesistimu; izinombolo zangempela zivela ekwakhiweni kwe-NFPA 13 kanye nesiphathimandla esinesigunya.
Amasistimu Amanzi, Omile, Angaphambi Kokusebenza Kanye Ne-Deluge Wonke Athatha Emthonjeni Ofanayo Wethangi
Izinhlobo ezine ezijwayelekile zamasistimu e-sprinkler ziyahluka ngendlela ezigcina ngayo amanzi nokuthi yini ebangela ukukhululwa, kodwa zonke ekugcineni zidinga umthombo wamanzi agciniwe ohlangabezana nokuhamba nesikhathi esidingekayo. Isistimu yamapayipi emanzi igcwele amanzi ngaso sonke isikhathi; isistimu yamapayipi omile igcina umoya ocindezelwe futhi igcwala lapho ivulwa; isistimu yangaphambi kokusebenza yengeza ukukhululwa kokutholwa; isistimu ye-deluge ivula wonke amakhanda ngasikhathi sinye ukuze ibhekane nengozi ephezulu.
Zonke izinhlobo zezifutho ziyaphela ethangini elifanayo ngokusebenzisa iphampu yomlilo efanayo, ngakho isigaba sethangi asishintshi — umfuno kanye nokucabanga kokukhululwa kuyashintsha. Ithangi likhethwa uma uhlobo lwesistimu selusungule ukuhamba, ubude besikhathi nokuthi ngabe kukhona ukubambezeleka kokutholwa okufanele kuhlanganiswe.
