Amathangi Okugcina Amanzi Ezinhlelo Zokuvikela Umlilo: Izinhlobo, Iqhaza Nokuhlanganiswa Kohlelo
Ithangi lokugcina amanzi okuzivikela emlilweni akusona isitsha esizimele kodwa iyisigcino samanzi esicindezelwe esikhulu esinosayizi, indawo, kanye nokuxhumana kwejiyometri okunqunywa uhlelo lokuzivikela emlilweni olusebenza ngaphansi kwalo — isifafaza, ihayidranti, ipayipi lokucima umlilo, noma i-deluge.
Onjiniyela bavame ukucacisa isitoreji samanzi okuvikela umlilo njengokungathi siyingxenye yemishini eyedwa: ithangi, umthamo, i-coating. Kodwa-ke ekufakweni okuhambisana nemithetho, ithangi liyingxenye yohlelo lokuvikela umlilo, futhi ukuziphatha kwalo kulawulwa uhlelo elulufunzayo. Isitoreji esifanayo esiboshwe ngamabhawudi senza umsebenzi ohlukile wobunjiniyela lapho sinikeza umsele wamanzi wengcindezi ephansi kunalapho sisebenza njengesiqiwu sepayipi eliqondile lesakhiwo esiphakeme. Le ndatshana ibheka ithangi njengengxenye yohlelo, ichaza ukuthi uhlobo ngalunye olukhulu lohlelo lokuvikela umlilo lusebenzisa kanjani isiqiwu, futhi ichaza izindawo zokuxhumana — ikakhulukazi isethi yephampu ye-NFPA 20 — ezinquma ukuthi ukufakwa kuzosebenza yini lapho kudingeka.
Ithangi Lamanzi Okuzivikela Emlilweni Liyisisekelo Sokuxhumana Samanzi Sohlelo Lonke
Wonke uhlelo olusebenzayo lokuvikela umlilo ludinga umthombo wamanzi oqinisekisiwe, futhi ithangi iyisibambiso esihlukanisa isidingo kusuka ekunikezweni kukamasipala. Lapho isigameko somlilo sivula amakhanda ezifutho noma siphula umgudu wamanzi ophambili, isidingo sokugeleza sivela ngokushesha futhi singadlula umfutho noma umthamo wedolobha okhona. Ithangi lokugcina ligcina indawo yokugcina amanzi leyo iphampu yomlilo eyiguqula ibe umfutho nokugeleza okudingekayo. Ngaphandle kwethangi elihlanganiswe ngendlela efanele, uhlelo olungaphansi — kungakhathaliseki ukuthi amapayipi, amavalvu, namakhanda aklanywe kahle kangakanani — alunakho okuzokwethula.
Uhlobo Ngalunye Lohlelo Lokuzivikela Emlilweni Lubeka Isidingo Esihlukile Kwithangi
Izindlela ezine eziyinhloko zokwakheka kwamasistimu zisebenzisa isiqiwu ngezindlela ezihlukene, futhi ithangi kufanele licaciswe ukuze lihambisane nesimo. Isistimu yokufafaza ngokuvamile idinga ukugeleza okulinganiselayo, okuqhubekayo isikhathi eside; isistimu ye-hydrant idinga ukugeleza okuphezulu ngamagagasi emijelweni yamapayipi; isistimu ye-standpipe ihlanganisa kokubili nezidingo zengcindezi eqondile; isistimu ye-deluge ivula wonke amakhanda ngesikhathi esisodwa futhi idinga ukugeleza okuphezulu kakhulu kwesikhashana esifushane. Ithebula elingezansi lifingqa indlela ithangi elixhumana ngayo nohlobo ngalunye lwesistimu.
Uhlobo Lohlelo | Iphethini Evamile Yesidingo | Indima Yethangi | Umbuso Oyinhloko Olawulayo |
Isifafazi esizenzakalelayo | Ukugeleza okulinganiselwe, isikhathi eside | Ukulawulwa Kwezinga Nokuphathwa Kokuchichima Kuvikela Kokubili Ithangi Nesistimu Exhunyiwe | NFPA 13 / EN 12845 |
Impompo yomlilo | Ukugeleza okuphezulu, ukuqhuma okungapheli | Umthombo wemifudlana yamapayipi kanye nokuxhumana kwamapompo | Ikhodi yomlilo yendawo / ukuxhumana kwe-NFPA 20 |
Ipayipi eliqinile le-Class I/III | Ukugeleza okuphezulu, ingcindezi eqondile | Gcina ama-riser okuhlinzeka ezitezi eziphezulu | Ukuxhumana kwe-NFPA 14 ne-NFPA 20 |
I-Deluge | Ukugeleza okuphezulu kakhulu kwesikhashana | Isitoreji sokukhishwa okuvulekile ngokuphelele | Isitoreji se-NFPA 15 / NFPA 22 |
Okuhlanganisiwe (okunezinhloso eziningi) | Isidingo esengeziwe | Isiqiwu esisodwa esabiwe, umthamo owengeziwe | Imithetho yokuhlanganisa ye-NFPA 22 |
Umphumela obalulekile ukuthi amasistimu ahlanganisiwe awathathi isidingo esikhulu esisodwa — athatha isamba sezidingo ezenzeka ngasikhathi sinye, okukhulisa ngqo umthamo wethangi odingekayo.
Ukuxhumana Phakathi Kwethangi Ne-NFPA 20 Pump Set Kuchaza Ukuthembeka Kwesistimu
Ithangi nephampu kuyiyunithi eyodwa ye-hydraulic. I-NFPA 20 ilawula ukuhlelwa kwephampu yomlilo, futhi ithangi kufanele linikeze isimo esizinzile sokudonsa: i-net positive suction head eyanele, ukugcwaliswa okulawulwa yi-float okugcina izinga lamanzi elidingekayo, kanye nokuhlelwa okuvimbela i-vortexing endaweni yokungena yephampu. I-jockey pump igcina ingcindezi yesistimu phakathi kwezigameko zokudingeka, kuyilapho iphampu yomlilo eyinhloko idonsa ethangini ukuze ihlangabezane nokugeleza nengcindezi elinganiselwe yesistimu. Uma ukuxhumana kwethangi kuncane kakhulu, kugcwele umoya, noma kubekwe ngendlela yokuthi kungakwazi ukuletha izinga eliphansi kakhulu elisebenzisekayo kuphampu, yonke isistimu iyahluleka kungakhathaliseki umthamo wethangi. Ukuhlelwa kokudonsa — okuqondile, ngokusebenzisa i-suction header, noma nge-vault evamile — kufanele kwakhiwe njengengxenye yethangi, hhayi ukufakwa ngemuva.
Ukukhethwa Kohlobo Lwethangi Kulawulwa Ingcindezi Yokusebenza Yesistimu kanye Nesu Lokugcwalisa
Ukukhetha phakathi kwethangi elishiselwe, eliboshiwe (GFS), noma elikakhonkolo kuncike endleleni uhlelo olugcwaliswa futhi olucindezelwa ngayo. Uhlelo olusizwa iphampu lungasebenzisa ithangi eliboshiwe elisezingeni eliphansi ngoba iphampu ye-NFPA 20 idala ingcindezi; uhlelo lwamandla adonsela phansi noma oluphakeme luncike ekhanda lethangi. Ithebula elingezansi libonisa ukuhlelwa kwamathangi nokufaneleka kohlelo.
Ukuhlelwa Kwethangi | Umthombo Wengcindezi | Ukufaneleka Kuhle Kakhulu Kohlelo | Inothi Lokuhlanganisa |
Kuboshwe ezingeni lomhlabathi (kusizwa ipompo) | Ipompo ye-NFPA 20 | Isifutho, isicishamlilo, isikhukhula | Ukwakheka kokudonsa kuyisixhumanisi esibalulekile |
Ephakeme / umbhoshongo | Ikhanda elimile | Ipayipi eliqondile, isifafazi esisebenza ngamandla adonsela phansi | Ikhanda lithatha indawo yepompo emizuzwini yokuqala |
Igumbi elingaphansi komhlaba | Ipompo noma ukudonsa | Izindawo ezinesikhala esilinganiselwe | Isithwathwa nokufinyelela kwe-NFPA 20 yokudonsa |
Okucindezelwe (komoya) | Isihlalo somoya | Amasistimu amancane, akude | Igcina ingcindezi ngaphandle kwepompo ye-jockey |
Kumaphrojekthi okuthekelisa nokusatshalaliswa okusheshayo, amathangi ensimbi acwebezelisiwe ahlanganiswe ngamabhawodi avame ukukhethwa ngoba igobolondo lifika njengamapuleti amboziwe futhi lihlanganiswa endaweni, okunciphisa umsebenzi wokwakha nokushisela obekuzodingeka emkhunjini oshiselwe.
Level Control And Overflow Management Protect Both The Tank And The Connected System
Ithangi lokuvikela umlilo kufanele ligcine umthamo walo odingekayo ngaso sonke isikhathi, kodwa futhi lixhunywe emthonjeni wamanzi wokugcwalisa okuwugcwalisa kabusha ngemva kokuhlolwa noma kokukhishwa. Uhlelo lwezinga lusebenzisa imithetho emibili: ithangi akumele lehle ngaphansi kwezinga eliphansi elisebenzisekayo elidingwa yipompo ye-NFPA 20, futhi akumele licwebe phezu kwezinga elizungezile. Izixwayiso zezinga eliphezulu neliphansi, ivalvu yokugcwalisa elawulwa yi-float, kanye nokuchichima okulinganiselwe kukhulula uhlelo ekuqaphelisweni kwesandla.
Ukuvikela Ekubandeni Nokungena Komoya Kufanele Kuhambisane Nomjikelezo Womsebenzi Wohlelo
Ithangi lokuzivikela emlilweni livame ukungasebenzi iminyaka, bese lifunwa ngokushesha. Ngenxa yokuthi amanzi amile, asengozini yokuba yiqhwa ezindaweni ezibandayo kanye nokuhlukana kwezigaba ezindaweni ezishisayo. Ukuvikelwa eqhweni — ukulandelela ukushisa, indawo evaliwe, noma umthombo wamanzi oshisayo — kufanele kucaciswe ngokuhambisana nezinga lokushisa lendawo, futhi ukungena komoya kanye nosayizi wendawo yokuphuma komoya kufanele kuvimbele i-vacuum noma ukwephulwa kwengcindezi ngesikhathi sokudonsa ngokushesha.
Icala Lomsebenzi
Le ndatshana ibhalwe njengomhlahlandlela wobunjiniyela wokugcinwa kwamanzi okuvikela umlilo, hhayi njengokucashunwa kwephrojekthi. Ikhono le-Center Enamel lokuhlinzeka ngamathangi amakhulu aboshiwe okusebenza komlilo likhonjiswa yizinhlelo esezilethiwe ezifana nedamu lokuvikela umlilo lase-India GFS (amathangi angu-3, 12,261 m³, 2024-06) kanye nokufakwa kwamanzi omlilo kwe-Singapore GFS (amathangi angu-2, 1,666 m³, 2026-01), ezakhiwe ngamazinga afanayo amathangi aboshiwe okubhekiselwa kuwo lapha. Lezo ziyizinkomba zokuvikela umlilo ezicashunwe njengomongo wekhono, hhayi njengokufakwa okuyisihloko salo mhlahlandlela.
