Indlela Yokuqinisekisa Ukutholakala Kwamanzi Kwabacishi Bomlilo Abaphezulu

Ukuqinisekisa amanzi okuvikela umlilo ezindaweni eziphakeme kudinga isu eliqinile nelihlanganisiwe. Abasebenzi bezakhiwo kumele basebenzise uhlelo oluhlanganisa amapayipi aqinile athembekile, indawo yokugcina amanzi enikezelwe, kanye namaphampu omlilo anamandla. Lezi zinhlelo zidinga ukusebenza okungaphazanyiswa, okuvikelwe ngamandla ayisisekelo ane-backup ephelele yejenereyitha yedizili.

Isihluthulelo Sokwethembeka:Ukunamathela ngokuqinile ezimisweni zokuhlola nokuhlola ze-NFPA kuqinisekisa lonke uhlelo, okuhlanganisa nokusebenza okuphezuluIphampu Yomlilo Eqondile Ye-Turbine, isebenza kahle uma ivuliwe. Lokhu kulungiswa okusebenzayo akunakuxoxiswana ngakho ukuqinisekisa ukuphepha kanye nobuqotho bohlelo.

Ukuklama Uhlelo Lokulethwa Kwamanzi Oluyinhloko

Ingaphakathi lesakhiwo esiphakemeuhlelo lokulethwa kwamanziumugqa wayo wokuqala wokuzivikela ngesikhathi somlilo. Umklamo ofanele uqinisekisa ukuthi abacishi bomlilo banokufinyelela kwamanzi ngokushesha nangokuthembekile kunoma yisiphi isitezi. Lokhu kudinga ukukhethwa ngokucophelela kwezinhlelo zamapayipi amile, ukuphathwa kwengcindezi okunembile, kanye nokuxhumeka okubekwe ngendlela efanele ukuze kusetshenziswe umnyango womlilo.

Ukukhetha Uhlelo Olufanele Lwepayipi Elimayo

Onjiniyela kumele bakhethe uhlelo lwepayipi elihambisana nezidingo ezithile zesakhiwo. I-National Fire Protection Association (NFPA) inikeza amazinga acacile okuqondisa lesi sinqumo esibalulekile. I-NFPA 14 ichaza izigaba ezintathu eziyinhloko zezinhlelo zepayipi elihambisanayo.

·Iklasi I: Lezi zinhlelo zinezixhumi zepayipi ezingamasentimitha angu-2½. Zenzelwe ukusetshenziswa kuphela yiminyango yomlilo kanye nabasebenzi bezimo eziphuthumayo abaqeqeshiwe.

·Isigaba II: Lezi zinhlelo zihlanganisa ukuxhumeka kwepayipi elingamasentimitha angu-1½. Zenzelwe ukusetshenziswa ngabantu abahlala esakhiweni abaqeqeshwe kuze kufike umnyango womlilo.

·Isigaba sesi-3: Lezi zinhlelo zinikeza inhlanganisela yokuxhumana okungu-1½-intshi no-2½-intshi, okunikeza ukuguquguquka kokubili kubahlali abaqeqeshwe kanye nabacimi bomlilo abangochwepheshe.

Ezindlini eziphakeme, uhlelo lwe-Class I oluzenzakalelayo lwamapayipi amanzi luyindinganiso. Lokhu kuqinisekisa ukuthi amanzi ahlala ekhona emapayipini, alungele ukusetshenziswa ngokushesha. Izindinganiso ezibalulekile ze-NFPA zibeka izidingo ezithile:

· I-NFPA 14kudinga amapayipi okuma azenzakalelayo kunoma yisiphi isakhiwo esingaphezu kwamamitha angu-75 ukuphakama.

· I-NFPA 101, iIkhodi Yokuphepha Kokuphila, kuqinisa lokhu ngokuyalela izinhlelo ze-Class I ezakhiweni ezikhethekile njengezakhiwo eziphakeme ukuqinisekisa ukuthi abacishi bomlilo banokugeleza nokucindezela okudingekayo.

Ukufaka Amavalvu Anciphisa Ukucindezeleka

Izakhiwo eziphakeme zikhiqiza umfutho omkhulu wamanzi ngenxa yokuphakama kwekholomu yamanzi. Amavalvu okunciphisa umfutho (ama-PRV) ayizinto ezibalulekile ezilawula lo mfutho, zivikela abacishi bomlilo emandleni aphezulu ayingozi ekuxhumekeni kwepayipi. Kunezinhlobo ezimbili eziyinhloko zama-PRV. Ama-PRV asebenza ngqo afakwa ekuxhumekeni kwepayipi uqobo. Ama-PRV asebenza ngokungaqondile afakwa emgqeni ngaphakathi kwamapayipi ukulawula umfutho wezindawo eziningi zokuphuma noma phansi lonke.

Ukwephulwa Kwesistimu KuyisihluthuleloUma i-PRV engaqondile isebenzisa ukuxhumana kwamapayipi okungaphezu kwamabili, amazinga e-NFPA adinga ukuthi kufakwe i-PRV yesibili ngokulandelana ukuze kusetshenziswe kabusha. Lokhu kuqinisekisa ukuthembeka kokusebenza noma ngabe ivalvu eyodwa yehluleka.

Ukuhlolwa okufanele akunakuxoxiswana ngakho ngala madivayisi abalulekile. I-NFPA 25, iIzinga Lokuhlola, Ukuhlola, kanye Nokugcinwa Kwezinhlelo Zokuvikela Umlilo Ezisekelwe Emanzini, ifuna ukuhlolwa kokugeleza okugcwele kwawo wonke ama-PRV njalo eminyakeni emihlanu. Lokhu kuhlolwa kuqinisekisa ukuthi ama-valve asebenza kahle ngaphansi kwezimo zokugeleza komlilo ezingokoqobo.

Ukuqinisekisa Ukuxhumana Okufinyelelekayo KoMnyango Wezomlilo

I-Fire Department Connection (FDC) iyisixhumanisi esibalulekile esivumela abacishi bomlilo ukuthi bangezelele ekuhlinzekweni kwamanzi ngaphakathi kwesakhiwo. Indawo yaso kanye nokubonakala kwaso kubalulekile ekuphenduleni okusheshayo okuphuthumayo. Amakhodi esakhiwo adinga izimpawu ezicacile neziqondile ku-FDC ngayinye.

Izimpawu kumele zichaze ngokucacile uhlelo olusetshenziswayo. Izindinganiso ze-NFPA zigunyaza ukubhalwa kwezinhlamvu ezithile ukuze kugwenywe ukudideka ngesikhathi sesimo esiphuthumayo.

Izidingo ezengeziwe zezimpawu zifaka:

·Ukukhombisa ukuthi ipayipi elimelelwe liyisistimu emanzi noma eyomile ngesandla.

·Ukubonisa ingcindezi yesistimu edingekayo uma idlula i-150 psi.

·Ukuchaza ngokucacile izitezi noma izindawo ezithile ezikhonzwayo uma i-FDC inganikezi sonke isakhiwo.

Okokugcina, abaphathi bezikhungo kumele balondoloze ukufinyelela okungenamkhawulo kuzo zonke i-FDC. Ukuxhumeka okuvinjiwe kungabangela ukubambezeleka okukhulu. Izithiyo ezivamile zifaka:

·Ukuhlobisa izimbali: Izihlahla, izihlahla, namatshe ahlotshisiwe.

·Izithiyo Ezenziwe Ngumuntu: Izimoto ezipakiwe, uthango, ama-pallet, kanye nezindonga zesikhashana.

·Imfucumfucu: Iqhwa, udoti, ngisho nezidleke zezinyoni noma izinyoni ngaphakathi kwezixhumanisi.

Ukuhlolwa okuvamile kuqinisekisa ukuthi lokhu kuxhumana kuhlala kubonakala, kufinyeleleka, futhi kulungele ukusetshenziswa ngokushesha amahora angama-24 ngosuku, izinsuku eziyi-7 ngesonto.

Ukuhlanganisa Nokunika Amandla Amaphampu Omlilo

Uhlelo lwamapayipi amile lwesakhiwo esiphakeme lusebenza kahle kuphela njengamaphampu asinikeza wona. Amaphampu omlilo ayinhliziyo yesistimu yokulethwa kwamanzi, ahlinzeka ngokucindezela nomthamo odingekayo wokulwa nomlilo kunoma yisiphi isitezi. Ukuhlanganiswa okufanele kuhilela usayizi oqondile, ukukhetha iphampu ngokucophelela, kanye nokuzibophezela okungapheli ekuhlinzekeni ngamandla athembekile.

Amaphampu Okulinganisa Ukucindezela Nokugeleza

Onjiniyela kumele balinganise kahle amaphampu omlilo ukuze banqobe amandla adonsela phansi kanye nokungqubuzana, bahambise amanzi ngengcindezi edingekayo kanye nesivinini sokugeleza kuya ekuxhumekeni kwepayipi okuphezulu kakhulu nokukude kakhulu. Iphampu encane izohluleka ukuletha amanzi anele, kuyilapho iphampu enkulu kakhulu ichitha amandla futhi ingadala ukucindezeleka okuphezulu okuyingozi.

Ukubalwa komfutho wokukhipha ipompo odingekayo kuyinqubo ehlelekile. Ihlanganisa zonke izidingo zomfutho kusukela embotsheni yomlilo bese isebenza emuva epompo. Ifomula eyisisekelo ihlanganisa izingxenye ezine ezibalulekile:

Ukucindezela Kokukhipha Iphampu = NP + FL + APP + ELEV

·Ukucindezela Kwe-Nozzle (NP):Ukucindezela okudingekayo embotsheni yomlomo ukuze kube nomfudlana womlilo ophumelelayo.

·Ukulahlekelwa Ukungqubuzana (FL):Ingcindezi elahlekayo njengoba amanzi ehamba ngamapayipi, amapayipi, izindololwane, kanye namavalvu. Lokhu kufaka phakathi ukungqubuzana okuvela ekukhuphukeni okuqondile kwepayipi elime ngqo.

·Ukucindezela Kwezinto Zikagesi (i-APP):Ukucindezeleka okulahlekelayo ngezinto zikagesi ezifana nepayipi leladi noma uxhumano lwe-wye.

·Ukuphakama (i-ELEV):Ingcindezi edingekayo ukuze kuphakanyiswe amanzi aye phansi komlilo. Inyawo ngalinye lokuphakama lidinga cishe i-0.433 psi.

Ithebula elilandelayo libonisa ukuthi la manani ahlangana kanjani ezimweni ezahlukene:

Izidingo zezinga lokugeleza zichazwa yi-NFPA 14. Ukuze uthole indawo ephakeme efakwe umbala obomvu ogcwele, imithetho ejwayelekile iyadingeka:

·Okungenani amalitha angu-500 ngomzuzu (gpm) epayipini lokuqala elimile.

·I-250 gpm eyengeziwe yepayipi ngalinye elilandelanayo.

·Ukugeleza okuphezulu okudingekayo okungu-1,000 gpm.

Ukukhetha Iphampu Yomlilo Eqondile Ye-Turbine

Ngezinhlelo zokusebenza eziphakeme, i-Vertical Turbine Fire Pump iyisinqumo esiyingqayizivele ngenxa yomklamo wayo oyingqayizivele kanye nezinzuzo zokusebenza. Ngokungafani namaphampu avundlile, lo modeli ulungele izakhiwo ezinamathangi okugcina amanzi angaphansi komhlaba.

Izinzuzo Eziyinhloko Zomklamo We-Vertical TurbineInjini itholakala ngaphezu komhlabathi ukuze kube lula ukuyilungisa, kuyilapho i-pump assembly ifakwa emthonjeni wamanzi. Lokhu kulungiselelwa kuthuthukisa isikhala saphansi, kuqeda isidingo sokuyibeka phansi, kunciphisa umsindo, futhi kuqinisekisa ukutholakala kwamanzi okuqhubekayo ngisho nasemithonjeni ejulile.

IIphampu Yomlilo Ye-TKFLO Diesel Engine Long Shaft Vertical Turbineikhombisa izinzuzo zalobu buchwepheshe. Yakhelwe ukuhlangabezana nezindinganiso eziqinile ze-GB6245-2006 kanye ne-NFPA, iqinisekisa ukuthembeka okungenakuqhathaniswa. Umklamo wayo othuthukisiwe we-hydraulic kanye nokwakhiwa okuqinile kwenza kube yisisombululo esihamba phambili sokuvikela umlilo okubalulekile ezakhiweni eziphakeme. I-Vertical Turbine Fire Pump inikeza ukuqina okuphezulu ngoba izingxenye zayo ezingaphansi kwamanzi azithinteki kalula yi-cavitation, okuyimbangela evamile yomonakalo wephampu.

Ukufakwa okufanele kubaluleke kakhulu ekusebenzeni kwesikhathi eside. Ngaphambi kokufakwa, amaqembu kumele aqinisekise ukuthi isisekelo silinganisiwe, kukhethwe imodeli efanele yephampu, futhi wonke amathuluzi adingekayo aselungile. Inqubo yokufaka ihilela ukusetha ngokucophelela i-baseplate, ukwehlisa nokuxhumanisa ikholomu nesitsha, kanye nokuqondisa ngokunembile umshayeli. Ukunamathela ngokuqinile eziqondisweni ze-NFPA 20 ngesikhathi sokusetha kuvimbela amaphutha avamile njengokungahambisani kahle kweshaft noma i-grouting engafanele eholela ekudlidlizeni nasekuhlulekeni kwangaphambi kwesikhathi.

Ukuvikela Amandla Ayisisekelo Nawokusekelayo Athembekile

Iphampu yomlilo ayisebenzi ngaphandle komthombo wamandla oqinisekisiwe. I-NFPA 20 ibeka imigomo eqinile yalokho ekubheka njengomthombo wamandla oyinhloko "othembekile" wephampu kagesi eqhutshwa yinjini. Umhlinzeki wosizo kumele abe nomlando wokuzinza, ngaphandle kokuphazamiseka okuhleliwe okungaphezu kwamahora amane aqhubekayo ngonyaka odlule. Ngaphezu kwalokho, i-voltage kumlawuli wephampu yomlilo ayikwazi ukwehla ngaphezu kuka-15% ngesikhathi sokuqalisa kwemoto noma u-5% ngesikhathi sokusebenza ngokugcwele.

Uma umthombo wamandla oyinhloko ungahlangabezani nalezi zindinganiso, umthombo wamandla okusekelayo onokwethenjelwa uyadingeka. Ezakhiweni eziphakeme, lokhu cishe njalo kusho ijeneretha kadizili esendaweni.

I-NFPA 25: Izidingo Zokuhlolwa Kwamafutha Kadizili

8.3.4.1Uphethiloli wedizili kufanele uhlolwe ukuthi uyawohloka okungenani njalo ngonyaka.

8.3.4.2Uma kutholakala ukuthi uphethiloli wedizili awusebenzi kahle... uphethiloli kufanele ulungiswe kabusha noma ushintshwe, ithangi lokuhambisa kufanele lihlanzwe ngaphakathi, bese kuthi isihlungi(izihlungi) sikaphethiloli wenjini sishintshwe.

Izinhlelo zokupompa ezisezingeni eliphezulu, njengalezo ezivela ku-TKFLO, zihlanganisa izinjini zikadizili ezinamandla ezivela emikhiqizweni edumile njenge-Cummins noma i-Deutz. Lezi zinjini zaziwa ngokuqala kwazo okuthembekile kanye nomthamo wazo omkhulu wokulayisha ngokweqile. Kodwa-ke, ukuthembeka kwenjini kuncike ngokuphelele kuphethiloli wayo. Uphethiloli kadizili wesimanje ungonakala endaweni yokugcina, okuholela ekuvinjweni kwezihlungi kanye nokwehluleka kwenjini ngesikhathi esiphuthumayo.

Ngenxa yalesi sizathu, i-NFPA 110 kanye ne-NFPA 25 zigunyaza ukwakhiwa nokugcinwa kwesistimu kaphethiloli okuqinile. Izidingo ezibalulekile zifaka:

·Ukunikezwa Kwamafutha Ahlanzekile:Uhlelo kumele lwakhiwe ukuze lugcine uphethiloli ungenamanzi kanye nezinto ezingcolisayo. Imigqa kaphethiloli egayiwe ayivunyelwe, njengoba i-sulfur kudizili ingasabela embozweni we-zinc futhi ingcolise injini.

·Isitoreji Esanele:Amathangi kaphethiloli kumele agcine uphethiloli owanele isikhathi esidingekayo sokusebenza kwesistimu, kodwa hhayi kakhulu kangangokuthi uphethiloli uhlala iminyaka eminingi bese ubola.

·Awekho Ama-valve Azenzakalelayo:I-NFPA 110 iyakwenqabela ama-valve asebenza ngokuzenzakalelayo emgqeni wokuphakelwa kukaphethiloli ukuvimbela ukuvalwa ngengozi kwemishini yokuphepha kophethiloli njenge-Vertical Turbine Fire Pump.

Ekugcineni, ukuhlanganisa iphampu eqinile nohlelo lwamandla kanye nophethiloli olunakekelwe kahle kuyindlela kuphela yokuqinisekisa ukuthi amanzi azogeleza lapho i-alamu ikhala.

Ukuqinisekisa Ukunikezwa Kwamanzi Okwanele Esakhiweni

Ubunjiniyela obufanele buhilela ukubala ivolumu efanele, ukubeka amathangi ngendlela efanele, nokuwavikela ekuwohlokeni.

Ukubala Umthamo Wokugcina Amanzi

Onjiniyela babala umthamo wokugcina amanzi odingekayo ngokusekelwe engcupheni ethile yomlilo yesakhiwo. I-NFPA 13,Izinga Elijwayelekile Lokufakwa Kwezinhlelo Zokutshiza, ihlukanisa izakhiwo ngokwezinga lazo lezingozi. Lokhu kuhlukaniswa kunquma ngqo isikhathi esincane okumelwe siqhubeke ngaso ukuphakelwa kwamanzi.

·Izindawo Ezinengozi Encane: Dinga isikhathi sokunikezwa kwamanzi okungenani imizuzu engama-30.

·Izindawo Ezivamile Ezinengozi: Udinga amanzi ahlala imizuzu engama-60 kuya kwengama-90.

Ivolumu ephelele edingekayo ingumkhiqizo wesidingo sokugeleza kwesistimu (isidingo sokufafaza kanye nesibonelelo somfudlana wepayipi) kanye nobude besikhathi obudingekayo. Isibonelo, uhlelo olufuna amalitha angu-250 ngomzuzu (gpm) isikhathi semizuzu engu-30 ludinga ithangi elingamalitha angu-7,500 (250 gpm x 30 min).

Ukubeka Amathangi Amanzi Ngendlela Efanele

Indawo yethangi lamanzi ithinta kakhulu imithwalo yesakhiwo, ingcindezi ye-hydraulic, kanye nezindleko zesistimu. Abaklami bezakhiwo bavame ukukhetha phakathi kokubeka amathangi ophahleni noma emazingeni aphakathi nesevisi. Isu ngalinye linikeza izinzuzo nezinkinga ezihlukile.

Indlela Ehlakaniphile YokuxubaEminye imiklamo yesimanje isebenzisa imodeli ehlanganisiwe ukuze isebenze kahle kakhulu. Isibonelo, iMotive Apartments ePerth, e-Australia, isebenzisa iphampu encane engaphansi komhlaba ukugcina ithangi lophahla ligcwele. Izitezi eziphezulu zikhonzwa ngamaphampu amancane okukhulisa, kanti izitezi ezingezansi zithola amanzi ngamandla adonsela phansi. Leli cebo lisindisa ugesi futhi liqinisekisa ukufinyelela kwamanzi ngisho nangesikhathi sokucima kukagesi.

Ukuvimbela Ukubola Nokubola

Amathangi okugcina amanzi kumele ahlale engenawo ukugqwala kanye nenhlabathi ukuqinisekisa ukuthembeka kohlelo. Ukugqwala kwenza isakhiwo sethangi sibe buthaka, kuyilapho inhlabathi ingavimba amapayipi kanye nezingxenye zephampu ezingcolile. Abaphathi bezikhungo kumele basebenzise uhlelo lokulungisa nokuvikela olusebenzayo.

Izindawo zangaphakathi zethangi zidinga izembozo eziqinile zokuvikela ukuze zakhe umgoqo phakathi kwamanzi nensimbi.
