Uburyo bwo kwemeza ko amazi azagera ku bazimya inkongi z'umuriro mu nyubako nini

Gutanga garanti y'amazi yo kuzimya inkongi mu nyubako ndende bisaba ingamba zikomeye kandi zihujwe. Abakora mu nyubako bagomba gushyira mu bikorwa uburyo buhuza imiyoboro yizewe, ububiko bw'amazi bwihariye, n'amapompo akomeye yo kuzimya inkongi. Ubu buryo busaba ko habaho imikorere idahinduka, bufite ingufu z'ibanze hamwe n'inyongeramusaruro yuzuye ya generator ya mazutu.

Urufunguzo rwo Kwizerwa:Kubahiriza cyane amabwiriza y'igenzura n'isuzuma rya NFPA bituma sisitemu yose, harimo n'imikorere myizaPompe yo gutwika umuriro ya Turbine ihagaze, ikora neza iyo ikora. Uku kubungabunga bidasubirwaho ntabwo bishobora kuganirwaho kugira ngo umutekano n'ubuziranenge bw'imikorere ya sisitemu bigerweho.

Gushushanya Sisitemu y'ingenzi yo Gutanga Amazi

Inyubako ndende y'amagorofasisitemu yo gutanga amazini wo murongo wa mbere w’ubwirinzi mu gihe cy’inkongi y’umuriro. Igishushanyo mbonera gifasha abazimya umuriro kubona amazi vuba kandi neza ku gisenge icyo ari cyo cyose. Ibi bisaba guhitamo neza uburyo bwo guhagarara kw’imiyoboro, gucunga neza umuvuduko w’amashanyarazi, no guhuza ishami rishinzwe kuzimya umuriro mu buryo bw’ingamba.

Guhitamo Sisitemu Ikwiye yo Guhagarara

Abahanga mu by'ubwubatsi bagomba guhitamo sisitemu y'imiyoboro ihagaze ihuye n'ibikenewe byihariye by'inyubako. Ishyirahamwe ry'Igihugu rishinzwe Kurinda Inkongi (NFPA) ritanga amahame asobanutse neza yo kuyobora iki cyemezo cy'ingenzi. NFPA 14 isobanura ibyiciro bitatu by'ingenzi by'imiyoboro ihagaze.

· Icyiciro cya mbere: Izi sisitemu zifite imiyoboro ya santimetero 1.5. Zagenewe gukoreshwa n'abazimya umuriro n'abakozi bashinzwe ubutabazi bw'ibanze bahuguwe.

· Icyiciro cya kabiri: Izi sisitemu zirimo imiyoboro ya santimetero 1.5. Zigenewe gukoreshwa n'abashinzwe kuzimya umuriro bahuguwe kugeza igihe ishami rishinzwe kuzimya umuriro rihageze.

· Icyiciro cya gatatu: Izi sisitemu zitanga uburyo bwo guhuza bwa santimetero 1.5 na santimetero 2.5, zitanga uburyo bworoshye bwo koroshya ababyitabiriye ndetse n'abazimya umuriro b'inzobere.

Ku nyubako ndende, sisitemu y'imiyoboro y'amazi yo mu cyiciro cya mbere ni yo isanzwe. Ibi bituma amazi ahora ari mu miyoboro, yiteguye gukoreshwa ako kanya. Amahame y'ingenzi ya NFPA agena ibisabwa byihariye:

·NFPA 14bisaba imiyoboro ihagaze yikora ku nyubako iyo ari yo yose ifite uburebure burenga metero 75.

·NFPA 101,Itegeko ry'umutekano w'ubuzima, ibi bishimangira ishyiraho sisitemu zo mu cyiciro cya mbere mu nyubako zihariye nk'inyubako ndende kugira ngo abazimya inkongi babone umuvuduko n'imbaraga bikenewe.

Gushyiramo Valve zigabanya umuvuduko

Inyubako ndende zitanga umuvuduko mwinshi w'amazi bitewe n'uburebure bw'inkingi y'amazi. Valves zigabanya umuvuduko (PRVs) ni ibintu by'ingenzi bicunga uyu muvuduko, bikarinda abazimya umuriro imbaraga nyinshi ziteje akaga ku muyoboro w'amazi. Hari ubwoko bubiri bw'ingenzi bwa PRVs. PRVs zikora akazi kataziguye zishyirwa ku muyoboro w'amazi ubwawo. PRVs zikora akazi kataziguye zishyirwa ku murongo mu miyoboro kugira ngo zigenzure umuvuduko w'amazi menshi cyangwa hasi hose.

Kugabanya Sisitemu ni ingenziIyo PRV itaziguye ikoresha imiyoboro irenga ibiri, amahame ya NFPA asaba ko hashyirwaho PRV ya kabiri mu buryo bukurikiranye kugira ngo ikore neza. Ibi bituma imikorere yayo ihora ikora neza nubwo valve imwe yangirika.

Gupima neza ntibishobora kuganirwaho kuri ibi bikoresho by'ingenzi. NFPA 25,Ibipimo ngenderwaho byo kugenzura, gupima no kubungabunga sisitemu zo kurinda inkongi zishingiye ku mazi, itegeka ko habaho ikizamini cyuzuye cy’amazi kuri PRV zose buri myaka itanu. Iki kizamini cyemeza ko valve zikora neza mu gihe cy’umuriro usanzwe.

Gushyira mu bikorwa uburyo ishami rishinzwe kuzimya umuriro rishobora guhuza abantu

Ishami rishinzwe kuzimya umuriro (FDC) ni ryo shingiro rituma abazimya umuriro bongera amazi yo mu nyubako. Aho iherereye n'uburyo igaragara ni ingenzi cyane kugira ngo habeho ubutabazi bwihuse. Amategeko agenga inyubako asaba ibimenyetso bisobanutse neza kandi byihariye kuri buri FDC.

Ibyapa bigomba kugaragaza neza uburyo bikorera. Amabwiriza ya NFPA ategeka inyuguti zihariye kugira ngo hirindwe urujijo mu gihe cy’impanuka.

Ibindi bisabwa ku byapa birimo:

·Kugaragaza niba umuyoboro uhagaze ari uburyo bworoshye cyangwa bwumisha bukoresheje intoki.

·Kugaragaza umuvuduko wa sisitemu ukenewe niba urenze psi 150.

·Gusobanura neza amagorofa cyangwa uduce runaka twakorerwamo niba FDC idatanga serivisi ku nyubako yose.

Hanyuma, abayobozi b'ibigo bagomba kugira uburenganzira bwo kugera kuri FDC zose nta nkomyi. Gufunga umurongo bishobora gutera gutinda gukabije. Inzitizi zikunze kugaragara zirimo:

·Gutunganya ubutaka: Ibiti, ibihuru, n'amabuye y'imitako.

·Inzitizi zakozwe n'abantu: Imodoka ziparitse, uruzitiro, amapaleti, n'inkuta z'agateganyo.

·Ibisigazwa: Urubura, imyanda, ndetse n'ibyari by'inyoni cyangwa ivubi mu miyoboro.

Igenzura rihoraho rituma izi connection zikomeza kugaragara, kuboneka, kandi ziteguye gukoreshwa ako kanya amasaha 24/7.

Guhuza no Gutanga Ingufu ku Mapompe y'Umuriro

Sisitemu y'imiyoboro miremire y'inyubako igira akamaro nk'uko ipompo ziyitanga zibikora. Ipompo zitanga amazi ni zo shingiro ry'uburyo bwo gutanga amazi, zitanga umuvuduko n'ingano ikenewe kugira ngo zirwanye umuriro ku igorofa iryo ari ryo ryose. Guhuza neza bisaba ingano ikwiye, guhitamo neza ipompo, no kwiyemeza gutanga ingufu zizewe.

Pompe zipima umuvuduko n'amazi

Abahanga mu by’imashini bagomba gupima neza pompe zitanga umuriro kugira ngo batsinde imbaraga z’uburemere n’ubushyuhe, batanga amazi ku gitutu n’umuvuduko ukenewe ku muyoboro uri kure cyane kandi uhuza imiyoboro. Pompe nini cyane ntishobora gutanga amazi ahagije, mu gihe pompe nini cyane itakaza ingufu kandi ishobora guteza igitutu kinini cyane.

Kubara umuvuduko ukenewe wo gusohora pompe ni inzira ikorwa mu buryo busanzwe. Iteranya ibikenewe byose by'umuvuduko uhereye ku ruziga rw'umuzimyamwoto ugasubira kuri pompe. Ishingiro ry'ibice bine by'ingenzi:

Umuvuduko wo gusohora pompe = NP + FL + APP + ELEV

·Umuvuduko w'akazuru (NP):Igitutu gikenewe ku munwa w'amazi kugira ngo umuriro ugende neza.

·Gutakaza Imiterere (FL):Umuvuduko ugabanuka uko amazi agenda anyura mu miyoboro, mu miyoboro, mu nkokora no mu mashini zifunga. Ibi birimo gukururana kw'umuyoboro uhagaze ubwawo.

·Umuvuduko w'ibikoresho (APP):Umuvuduko ugabanuka binyuze mu bikoresho nk'umuyoboro w'amashanyarazi cyangwa umuyoboro w'amazi.

·Uburebure (ELEV):Igitutu gikenewe kugira ngo amazi azamuke agere ku gisenge cy'umuriro. Buri ntambwe y'uburebure isaba hafi 0.433 psi.

Imbonerahamwe ikurikira igaragaza uburyo izi ndangagaciro zihurira mu bihe bitandukanye:

Ibisabwa ku gipimo cy'amazi anyuramo bigenwa na NFPA 14. Ku gisenge cyuzuye gifite ibara ry'umuhondo, ibi bigenwa n'amategeko asanzwe:

·Nibura litiro 500 ku munota (gpm) ku muyoboro wa mbere uhagarara.

·Inyongera ya 250 gpm kuri buri muyoboro ukurikira.

·Urugendo ntarengwa rusabwa rwa 1.000 gpm.

Guhitamo Pompe y'umuriro ya Turbine ihagaze

Ku bikoresho birebire, Vertical Turbine Fire Pump ni amahitamo adasanzwe bitewe n'imiterere yayo yihariye n'akamaro k'imikorere. Bitandukanye na pompe zitambitse, iyi moderi ni nziza ku nyubako zifite ibigega byo kubika amazi munsi y'ubutaka.

Ibyiza by'ingenzi by'igishushanyo cya Turbine ihagazeMoteri iri hejuru y'ubutaka kugira ngo yorohereze kuyitunganya, mu gihe igikoresho cyo kuyipompa kiri mu isoko y'amazi. Iyi miterere ifasha mu kunoza umwanya wo hasi, ikagabanya gukenera kuyishyiramo amazi, ikagabanya urusaku, kandi igatuma amazi aboneka neza ndetse no mu bigega binini.

ItsindaPompe y'umuriro ya TKFLO moteri ya mazutu ifite umuvuduko muremure kandi ihagazeIgaragaza ibyiza by'iri koranabuhanga. Yakozwe kugira ngo ihuze n'amahame akomeye ya GB6245-2006 na NFPA, ihamya ko yizewe cyane. Imiterere yayo ihanitse ya hydraulic n'imiterere yayo ikomeye bituma iba igisubizo gikomeye mu kurinda inkongi z'umuriro mu nyubako ndende. Pompe yo gutwika umuriro ya Turbine ihagaze neza itanga uburambe bwiza kuko ibice byayo biri munsi y'amazi bidakunze kwangirika, ari na yo mpamvu ikunze kwangiza pompe.

Gushyiraho neza ni ingenzi cyane kugira ngo imikorere ikomeze igihe kirekire. Mbere yo gushyiraho, amakipe agomba kugenzura ko urufatiro ruringaniye, hatoranijwe icyitegererezo cy’ipompo gikwiye, kandi ibikoresho byose bikenewe bikaba byateguwe. Gushyiraho bisaba gushyiraho neza inkingi y’ibanze, kumanura no guhuza inkingi n’igice cy’inyuma, no gushyira neza umushoferi. Gukurikiza amabwiriza ya NFPA 20 mu gihe cyo gushyiraho birinda amakosa akunze kugaragara nko kugorana kw’imigozi cyangwa gukurura nabi bigatera guhinda no kwangirika vuba.

Kurinda imbaraga z'ibanze n'izishingiye ku bushobozi bwo kuzigama

Pompe yo kuzimya umuriro ntacyo imaze idafite isoko y'amashanyarazi yizewe. NFPA 20 ishyiraho ibipimo bihamye ku byo ifata nk'isoko y'amashanyarazi "yizewe" kuri pompe ikoresha moteri y'amashanyarazi. Utanga serivisi agomba kuba afite amateka yo kudahindagurika, nta guhagarara ku buryo butunguranye kurenza amasaha ane akurikirana mu mwaka ushize. Byongeye kandi, ingufu z'amashanyarazi ku imashini igenzura pompe yo kuzimya umuriro ntizishobora kugabanukaho 15% mu gihe moteri itangiye gukora cyangwa 5% mu gihe cyose ikora.

Iyo isoko y'amashanyarazi y'ibanze itujuje ibi bipimo, isoko y'amashanyarazi yizewe ni ngombwa. Ku nyubako ndende, ibi hafi ya byose bivuze moteri ya mazutu iri aho.

NFPA 25: Ibisabwa mu gupima mazutu

8.3.4.1Amavuta ya mazutu agomba gupimwa niba yangiritse nibura buri mwaka.

8.3.4.2Iyo hagaragaye ko lisansi ya mazutu idahagije… lisansi igomba kuvugururwa cyangwa gusimbuzwa, ikigega cy’ibikoresho kigomba gusukurwa imbere, kandi akayunguruzo k’amavuta ya moteri kagahindurwa.

Sisitemu zo kuvoma zifite ubuziranenge, nk'iza TKFLO, zihuza moteri zikomeye za mazutu zikomoka ku bicuruzwa byemewe nka Cummins cyangwa Deutz. Izi moteri zizwiho gutangiza neza no gukoresha imbaraga nyinshi. Ariko, kwizera kwa moteri biterwa gusa na lisansi yayo. Amavuta ya mazutu agezweho ashobora kwangirika mu bubiko, bigatuma moteri iziba kandi moteri igapfa mu gihe cy'impanuka.

Kubera iyo mpamvu, NFPA 110 na NFPA 25 bitegeka imiterere n'isukura ry'uburyo buhanitse bwa lisansi. Ibisabwa by'ingenzi birimo:

·Gutanga lisansi isukuye:Iyi sisitemu igomba kuba yakozwe kugira ngo irinde lisansi n'amazi n'ibindi bihumanya. Imiyoboro ya lisansi ikoreshwa muri galansi irabujijwe, kuko sulfur muri mazutu ishobora kugirana ingaruka n'igishishwa cya zinc igahumanya moteri.

·Ububiko buhagije:Ibigega bya lisansi bigomba kubika lisansi ihagije ijyanye n'igihe gisabwa cya sisitemu, ariko ntibigomba kuba bihari cyane ku buryo lisansi imara imyaka myinshi ikangirika.

·Nta Valves zikora mu buryo bwikora:NFPA 110 ibuza vali zikoresha lisansi mu buryo bwikora kugira ngo hirindwe ko lisansi ifungwa ku buryo butunguranye ku bikoresho bikingira ubuzima nka Vertical Turbine Fire Pump.

Amaherezo, guhuza pompe ikomeye n'amashanyarazi n'uburyo bwo gukoresha lisansi mu buryo bwitondewe ni bwo buryo bwonyine bwo kwemeza ko amazi azatemba igihe inzogera ivuze.

Kubona amazi ahagije aho hantu

A pompe ikomeyen'umuyoboro w'amazi wakozwe neza ntacyo bimara iyo nta mazi ahagije kandi yagenewe. Ibigega byo kubika amazi aho hantu bitanga ubu buryo bw'ingenzi, bigatuma abazimya umuriro babona amazi bakeneye, hatitawe ku buryo bw'ubuyobozi bw'umujyi. Guhanga neza bikubiyemo kubara ingano ikwiye, gushyira ibigega mu buryo bw'ikoranabuhanga, no kubirinda kwangirika.

Kubara ingano y'amazi abikwa

Abahanga mu by'imashini babara ingano y'amazi akenewe bakurikije ibyago by'inkongi by'umuriro. NFPA 13,Ibipimo ngenderwaho byo gushyiraho sisitemu zo kunyunyuza, ishyira inyubako mu byiciro hakurikijwe urwego rw'ibyago byazo. Iri shyirahamwe rigena mu buryo butaziguye igihe ntarengwa amazi agomba kumara.

·Imiturire y'abantu bafite ibyago byoroheje: Bisaba ko amazi aba ari mu gihe cy'iminota 30.

·Imiturire isanzwe y'ibiza: Bikeneye amazi amara iminota 60 kugeza kuri 90.

Ingano yose isabwa ni umusaruro w'ubushyuhe bw'amazi bukoreshwa muri sisitemu (ubushyuhe bwo gusunika hamwe n'uburyo bwo gukoresha imiyoboro y'amazi) n'igihe gisabwa. Urugero, sisitemu isaba litiro 250 ku munota (gpm) mu gihe cy'iminota 30 isaba ikigega cya litiro 7.500 (250 gpm x iminota 30).

Gushyira mu buryo bw'ingamba ibigega by'amazi

Aho ikigega cy'amazi giherereye bigira ingaruka zikomeye ku buremere bw'inyubako, umuvuduko w'amazi, n'ikiguzi cya sisitemu. Abashushanya inyubako bakunze guhitamo hagati yo gushyira ibigega ku gisenge cyangwa ku rwego rwo hagati rwa serivisi. Buri ngamba itanga ibyiza n'ibibi bitandukanye.

Uburyo bw'ikoranabuhanga rigezwehoImiterere imwe n'imwe igezweho ikoresha icyitegererezo cy'ubwoko butandukanye kugira ngo ikore neza cyane. Urugero, Motive Apartments i Perth, muri Ositaraliya, ikoresha pompe nto yo munsi y'ubutaka kugira ngo ikigega cyo hejuru kigume cyuzuye. Igorofa ryo hejuru rikoreshwa na pompe nto zo kongera ingufu, mu gihe igorofa ryo hasi rihabwa amazi binyuze mu mbaraga z'uburemere. Iyi ngamba izigama amashanyarazi kandi ikanizeza ko amazi agera no mu gihe cy'ibura ry'amashanyarazi.

Gukumira imyanda n'ingese

Ibigega byo kubikamo amazi bigomba kuguma nta ngeso mbi n'ibishishwa kugira ngo sisitemu ibe ihamye. Ingeso mbi zigabanya imiterere y'ikigega, mu gihe ibishishwa bishobora kuziba imiyoboro n'ibice bya pompe byanduye. Abayobozi b'ibigo bagomba gushyira mu bikorwa gahunda yo kubungabunga no kurinda.

Ubuso bw'imbere mu kigega busaba irangi rikomeye ryo kurinda kugira ngo bube uruzitiro hagati y'amazi n'icyuma.

· Imiringoti ya Epoxy: Udupira twa epoxy dugezweho kandi dufite ubushobozi bwo hejuru kandi twemewe na NSF 61 dutanga uburinzi bwiza kandi burambye kandi dufite umutekano ku miyoboro y'amazi meza.

·Imyenda ya seramike: Irangi rya phosphate rikozwe muri ceramic rihuza imiti ritanga ubudahangarwa bwiza mu bidukikije bikomeye binyuze mu gufatana neza n'icyuma.

Gukurikiza amabwiriza nka AWWA D102 bituma irangi rikoreshwa neza mu gihe cy’ubuzima bushobora kugera ku myaka mirongo itatu. Byongeye kandi, imiterere myiza y’ikigega ikubiyemo ibintu nk’ibice birwanya imiyaga ku gice cyo gukurura ipompo. Kugumana umwanya uhagije hagati y’iki gice n’aho kiri hasi ni ingenzi kugira ngo hirindwe ko imyanda yajya mu buryo bwo kurinda inkongi.

Gushyira mu bikorwa Porotokoli Ikomeye yo Kubungabunga no Gupima

Igishushanyo mbonera cya sisitemu yo kurinda inkongi y'umuriro ni cyiza gusa iyo ibungabunzwe. Ba nyir'inyubako n'abayobozi b'inyubako bagomba gukoresha amabwiriza y'igenzura, isuzuma, no kubungabunga (ITM) kugira ngo buri gice gikora uko cyagenwe. Ubu buryo bwo gukora buyobowe n'amahame ya NFPA, ni bwo buryo bwonyine bwo kwemeza ko sisitemu ikora neza mu gihe cy'impanuka.

Gukurikira igenzura rya buri munsi, buri cyumweru, n'ukwezi

Gusuzuma buri gihe ibintu bikirinda ko ibintu bito bihinduka ingaruka mbi. Abakozi b'ikigo bagomba kugenzura buri gihe niba hari inenge zisanzwe zishobora kwangiza sisitemu.

·Ibisabwa mu cyumba cyo gupompa:Icyumba kigomba kugira ubushyuhe buhagije (hejuru ya dogere seritiyeli 40 kuri mazutu ifite ibyuma bishyushya) kandi kikagira ibikoresho bifasha guhumeka neza.

·Amateraniro y'imiyoboro y'amazi:Imiyoboro ikenera gusuzumwa niba hari ibihumyo, ibikomere, cyangwa ibyangiritse. Imiyoboro ikoreshwa mu miyoboro igomba kuba ihari, idakingiye, kandi igakora neza.

·Ibikarito n'aho bihurira:Utubati tw’amazi tugomba gufungura neza, kandi Ishami rishinzwe kuzimya umuriro (FDCs) rigomba kuguma rigaragara kandi rigenzurwa, rifite imipfundikizo n’udupira tuzunguruka neza.

·Ibipimo:Abatekinisiye bagomba gusimbuza cyangwa kuvugurura ibipimo buri myaka itanu kugira ngo barebe ko bigumana ukuri mu kigero cya 3% by'ubunini bwabyo bwose.

Gukora ibizamini by'umwaka byuzuye

Ikizamini cyuzuye ngarukamwaka cyerekana imikorere y’ipompo ikoresha umuriro. Abakozi babishoboye bagomba gukora iki kizamini kugira ngo barebe ko ipompo yujuje ibisabwa mu buryo bw’umwimerere. Ubu buryo bukubiyemo intambwe nyinshi z’ingenzi:

1. Tegura Sisitemu:Abatekinisiye bahuza imiyoboro y'amazi n'ibikoresho byemewe byo gupima cyangwa ahantu ho gusohora amazi habigenewe.

2. Pima igipimo cy'umuvuduko w'amazi:Bakoresha pompe kugira ngo bapime umusaruro wayo mu buryo butatu butandukanye: guhindagurika kw'amazi (nta muvuduko wayo), 100% by'ubushobozi bwayo, na 150% by'ubushobozi bwayo.

3. Amakuru yo kwandika:Mu gihe cy'igerageza, bandika amakuru y'ingenzi, harimo umuvuduko wa pompe, imbaraga zo gukurura no gusohora amazi, hamwe n'imbaraga z'amashanyarazi n'umuvuduko w'amashanyarazi.

4.Sesengura Ibisubizo:Amakuru yakusanyijwe aragaragazwa kandi akagereranywa ukurikije ibyagaragajwe n'uruganda rwa pompe ndetse n'ibyavuye mu isuzuma ryakozwe mbere kugira ngo byemezwe imikorere.

Amasaha asabwa yo gukora
Mu gihe cy'igeragezwa rya buri mwaka, pompe zikoresha moteri y'amashanyarazi zigomba gukora nibura iminota 10, mu gihe pompe zikoresha moteri ya mazutu zigomba gukora nibura iminota 30.

Gukurikiza NFPA 25 kugira ngo sisitemu ikomeze kuba nziza

NFPA 25,Ibipimo ngenderwaho byo kugenzura, gupima no kubungabunga sisitemu zo kurinda inkongi zishingiye ku mazi, ni ubuyobozi bufite ububasha bwo kubahiriza ubusugire bwa sisitemu. Gukurikiza amategeko si amahitamo; ni itegeko rikurikizwa mu nzego nyinshi. Kutayubahiriza bishobora gutera amande menshi, ubwishingizi buhagarikwa, ndetse n'uburyozwe bukomeye. Iri tegeko ritegeka gahunda yuzuye y'imirimo.

Amaherezo, izi gahunda zemeza ko buri vali, umuyoboro, na pompe byiteguye gukora, bikarinda imitungo n'ubuzima bw'abantu.
