Iyini I-NFPA Yephampu Yamanzi Omlilo
I-National Fire Protection Association (NFPA) inamazinga amaningana aphathelene namaphampu amanzi omlilo, ikakhulukazi i-NFPA 20, “Okujwayelekile Ukufakwa Kwamaphampu Amisiwe Okuvikela Umlilo.” Leli zinga lihlinzeka ngemihlahlandlela yokuklama, ukufakwa, nokugcinwa kwamaphampu omlilo asetshenziswa ezinhlelweni zokuvikela umlilo.
Amaphuzu abalulekile avela ku-NFPA 20 afaka:
Izinhlobo zamaphampu:
Ihlanganisa izinhlobo ezahlukene zeamaphampu okucisha umlilo, okuhlanganisa amaphampu amaphakathi, amaphampu amahle okuthutha abantu, nokunye.
Izidingo zokufaka:
Iveza izidingo zokufakwa kwamaphampu ezicishamlilo, okuhlanganisa indawo, ukufinyeleleka, nokuvikelwa ezicini zemvelo.
Ukuhlola Nokunakekela:
I-NFPA 20 icacisa izinqubo zokuhlola kanye nezinqubo zokunakekela ukuze kuqinisekiswe ukuthi amaphampu omlilo asebenza ngempumelelo lapho kudingeka.
Amazinga Okusebenza:
Izinga lihlanganisa indlela yokusebenza okufanele amaphampu omlilo ahlangabezane nayo ukuze kuqinisekiswe ukutholakala kwamanzi okwanele kanye nokucindezela kwemisebenzi yokucisha umlilo.
Ukunikezwa kwamandla kagesi:
Ibhekana nesidingo semithombo yamandla ethembekile, okuhlanganisa nezinhlelo zokusekelayo, ukuze kuqinisekiswe ukuthi amaphampu omlilo angasebenza ngesikhathi sezimo eziphuthumayo.
Kusukela ku-nfpa.org, ithi i-NFPA 20 ivikela impilo nempahla ngokuhlinzeka ngezidingo zokukhethwa nokufakwa kwamaphampu ukuze kuqinisekiswe ukuthi amasistimu azosebenza njengoba kuhloswe ukuletha amanzi anele nathembekile esimweni esiphuthumayo somlilo.
Indlela yokubalaIphampu yamanzi omliloIngcindezi?
Ukuze ubale ingcindezi yephampu yomlilo, ungasebenzisa ifomula elandelayo:
Ifomula:
Kuphi:
· P = Ukucindezela kwephampu ku-psi (amaphawundi ngeyintshi yesikwele)
· Q = Izinga lokugeleza ngamalitha ngomzuzu (GPM)
· H = Ingqikithi yekhanda eliguqukayo (TDH) ezinyaweni
· F = Ukulahleka kwefriction ku-psi
Izinyathelo Zokubala Ukucindezela Kwephampu Yomlilo:
Nquma Izinga Lokugeleza (Q):
· Thola izinga lokugeleza elidingekayo lesistimu yakho yokuvikela umlilo, ngokuvamile eshiwo ku-GPM.
Bala Total Dynamic Head (TDH):
· Inhloko Emile: Kala ibanga eliqondile ukusuka emthonjeni wamanzi ukuya endaweni ephakeme kakhulu yokuphuma kwamanzi.
· Ukulahleka Kwefriction: Bala ukulahleka kokungqubuzana kusistimu yamapayipi usebenzisa amashadi okulahlekelwa ukungqubuzana noma amafomula (njengesibalo se-Hazen-Williams).
· Ukulahleka Kokuphakama: I-akhawunti yanoma yiziphi izinguquko zokuphakama ohlelweni.
[TDH= I-Static Head + Friction Loss + Elevation Loss]
Bala Ukulahleka Kwe-Friction (F):
· Sebenzisa amafomula afanelekile noma amashadi ukuze unqume ukulahleka kokungqubuzana ngokusekelwe kusayizi wepayipi, ubude, nezinga lokugeleza.
Xhuma Amanani Kufomula:
· Faka esikhundleni amanani we-Q, H, no-F kufomula yokubala umfutho wephampu.
Isibonelo sokubala:
· Izinga lokugeleza (Q): 500 GPM
· Ingqikithi Yekhanda Elinamandla (H): izinyawo eziyi-100
· Ukulahleka Kwe-Friction (F): 10 psi
Ukusebenzisa ifomula:
Okucatshangelwayo Okubalulekile:
· Qinisekisa ukuthi umfutho obaliwe uhlangabezana nezidingo zohlelo lokuvikela umlilo.
· Bheka njalo amazinga e-NFPA namakhodi endawo ukuze uthole izidingo ezithile nemihlahlandlela.
Xhumana nonjiniyela wokuvikela umlilo ngamasistimu ayinkimbinkimbi noma uma ungaqiniseki nganoma yiziphi izibalo.
Ukuhlola Kanjani Ukucindezela Kwephampu Yomlilo?
Ukuhlola umfutho wephampu yomlilo, ungalandela lezi zinyathelo:
1. Qoqa Izinsiza Ezidingekayo:
I-Pressure Gauge: Qinisekisa ukuthi unegeji yengcindezi elinganisiwe engakala ibanga lokucindezela elilindelekile.
Ama-Wrenches: Okokuxhuma igeji empompini noma epayipini.
Igiya Lokuphepha: Gqoka izinto zokuphepha ezifanele, okuhlanganisa amagilavu nezibuko.
2. Thola Imbobo Yokuhlola Ingcindezi:
Khomba imbobo yokuhlola ingcindezi ohlelweni lwephampu yomlilo. Lokhu kuvame ukutholakala ohlangothini lokuphuma lwephampu.
3. Xhuma i-Pressure Gauge:
Sebenzisa okokufaka okufanele ukuze uxhume igeji yokucindezela embobeni yokuhlola. Qinisekisa ukuvaleka okuqinile ukuze uvimbele ukuvuza.
4. Qala Iphampu Yomlilo:
Vula iphampu yomlilo ngokulandela imiyalelo yomkhiqizi. Qinisekisa ukuthi isistimu ixhunyiwe futhi ilungele ukusebenza.
5. Qaphela Ukufundwa Kwengcindezi:
Uma iphampu isebenza, bheka ukufundwa kwengcindezi kugeji. Lokhu kuzokunikeza ukucindezela kokukhipha kwepompo.
6. Rekhoda Ingcindezi:
Qaphela ingcindezi yokufunda kumarekhodi akho. Qhathanisa nengcindezi edingekayo ecaciswe ekwakhiweni kwesistimu noma kumazinga e-NFPA.
7. Hlola ukuhlukahluka:
Uma kusebenza, hlola ingcindezi ngamanani okugeleza ahlukene (uma uhlelo luvuma) ukuze uqinisekise ukuthi iphampu isebenza ngempumelelo kulo lonke uhla lwayo.
8. Vala Iphampu:
Ngemuva kokuhlola, vala ngokuphephile iphampu bese unqamula igeji yokucindezela.
9. Hlola Izinkinga:
Ngemva kokuhlola, hlola isistimu ukuze uthole noma yikuphi ukuvuza noma okungavamile okungase kudinge ukunakwa.
Okucatshangelwayo Okubalulekile:
Ukuphepha Okokuqala: Ngaso sonke isikhathi landela izimiso zokuphepha lapho usebenza namaphampu omlilo namasistimu anengcindezi.
Ukuhlola Okuvamile: Ukuhlolwa kwengcindezi evamile kubalulekile ukuze kugcinwe ukwethembeka kwephampu yomlilo.
Ithini Ingcindezi Encane Eyinsalela Yephampu Yomlilo?
Ingcindezi encane eyinsalela yamaphampu omlilo ngokuvamile incike ezidingweni ezithile zohlelo lokuvikela umlilo namakhodi endawo. Nokho, indinganiso evamile ukuthi ingcindezi encane eyinsalela kufanele okungenani ibe ngu-20 psi (amaphawundi ngeyintshi yesikwele) endaweni yokukhipha ipayipi elikude kakhulu phakathi nezimo zokugeleza okukhulu.
Lokhu kuqinisekisa ukuthi kunengcindezi eyanele yokuletha amanzi ngendlela ephumelelayo ohlelweni lokucisha umlilo, njengezifafazi noma amapayipi.
Amaphampu e-centrifugal ahlukanisa ikhese evundlile athobelana ne-NFPA 20 kanye nezidingo zesicelo ezisohlwini lwe-UL kanye nokufakwa okufanelekile kokuhlinzeka ngamanzi ezinhlelweni zokuvikela umlilo ezakhiweni, ezimbonini zezimboni nasemagcekeni.
