Yintoni i-NFPA yeMpompo yaManzi oMlilo
Umbutho woKhuseleko loMlilo weSizwe (i-NFPA) unemigangatho emininzi ephathelele kwiimpompo zamanzi omlilo, ngokuyintloko i-NFPA 20, eyi-"Standard for the Installation of Stationary Pumps for Fire Protection." Lo mgangatho ubonelela ngezikhokelo zoyilo, ukufakwa, kunye nokugcinwa kweempompo zomlilo ezisetyenziswa kwiinkqubo zokukhusela umlilo.
Amanqaku aphambili asuka kwiNFPA 20 abandakanya:
Iindidi zeempompo:
Ibandakanya iintlobo ezahlukeneyo zeiimpompo zokucima umlilo, kubandakanywa iimpompo ze-centrifugal, iimpompo zokufuduka ezilungileyo, kunye nabanye.
IiMfuno zoFakelo:
Ichaza iimfuno zokufakelwa kweempompo zomlilo, kubandakanywa indawo, ukufikeleleka, kunye nokukhuselwa kwizinto ezisingqongileyo.
Uvavanyo kunye noLondolozo:
I-NFPA 20 ichaza imigaqo yovavanyo kunye nezenzo zokulondoloza ukuqinisekisa ukuba iimpompo zomlilo zisebenza ngokufanelekileyo xa zifuneka.
ImiGangatho yokuSebenza:
Umgangatho uquka indlela yokusebenza ekufuneka iimpompo zomlilo zihlangane ukuze kuqinisekiswe ukunikezelwa kwamanzi okwaneleyo kunye noxinzelelo kwimisebenzi yokucima umlilo.
Ukunikezwa Amandla:
Ijongana nesidingo semithombo yamandla ethembekileyo, kubandakanywa neenkqubo zokugcina, ukuqinisekisa ukuba iimpompo zomlilo zinokusebenza ngexesha likaxakeka.
Ukusuka ku-nfpa.org, ithi i-NFPA 20 ikhusela ubomi kunye nepropathi ngokubonelela ngeemfuno zokukhethwa kunye nokufakwa kweempompo ukuqinisekisa ukuba iinkqubo ziya kusebenza njengoko kujongwe ukuhambisa amanzi aneleyo kunye athembekileyo kwimeko yongxamiseko yomlilo.
Indlela yokubalaImpompo yamanzi omliloUxinzelelo?
Ukubala uxinzelelo lwempompo yomlilo, ungasebenzisa le fomula ilandelayo:
Ifomula:
Apho:
· P = Uxinzelelo lwempompo kwi-psi (iiponti nge-intshi nganye)
· Q = Izinga lokuhamba ngeegaloni ngomzuzu (GPM)
· H = Iyonke intloko eguquguqukayo (TDH) ezinyaweni
· F = Ukulahleka kwefriction kwi-psi
Amanyathelo okubala Uxinzelelo lwePump yoMlilo:
Misela uMyinge wokuHamba (Q):
· Chonga izinga lokuqukuqela elifunekayo kwinkqubo yakho yokukhusela umlilo, edla ngokuchazwa kwiGPM.
Bala Itotali yeNtloko eDynamic (TDH):
· Intloko engatshintshiyo: Yenza umlinganiselo womgama othe nkqo ukusuka kumthombo wamanzi ukuya kweyona ndawo iphezulu yokukhupha.
· Ilahleko yefriction: Bala ilahleko yokukhuhlana kwinkqubo yemibhobho usebenzisa iitshati zokulahleka kwefriction okanye iifomula (ezifana neHazen-Williams equation).
· Ilahleko yoMphakamo: Iakhawunti yalo naluphi na utshintsho lokuphakama kwesistim.
[TDH= Intloko engatshintshiyo + Ilahleko yokuNxulumana + neLahleko yoMphakamo]
Bala iLass Friction (F):
· Sebenzisa iifomula ezifanelekileyo okanye iitshathi ukumisela ilahleko yokukhuhlana ngokusekelwe kubungakanani bombhobho, ubude, kunye nesantya sokuhamba.
Nxulumanisa amaxabiso kwiFomula:
· Faka amaxabiso e-Q, H, kunye no-F endaweni yefomula ukubala uxinzelelo lwempompo.
Umzekelo wokubala:
· Umlinganiselo wokuHamba (Q): 500 GPM
· I-Total Dynamic Head (H): iinyawo ze-100
· Ukulahleka kweFriction (F): 10 psi
Ukusebenzisa ifomula:
Iingqwalasela ezibalulekileyo:
· Qinisekisa ukuba uxinzelelo olubaliweyo luhlangabezana neemfuno zenkqubo yokukhusela umlilo.
· Soloko ubhekisa kwimigangatho yeNFPA kunye neekhowudi zasekuhlaleni kwiimfuno ezithile nezikhokelo.
• Dibana nenjineli yokhuseleko lomlilo malunga neenkqubo ezintsonkothileyo okanye ukuba akuqinisekanga ngazo naziphi na izibalo.
Ulujonga njani uxinzelelo lwePump yoMlilo?
Ukujonga uxinzelelo lwempompo yomlilo, unokulandela la manyathelo:
1. Qokelela izixhobo eziyimfuneko:
I-Pressure Gauge: Qinisekisa ukuba une-calibrated pressure gauge enokulinganisa udidi loxinzelelo olulindelekileyo.
Izitshixo: Ukudibanisa igeyiji kwimpompo okanye umbhobho.
IsiXhobo soKhuseleko: Nxiba izixhobo ezifanelekileyo zokhuseleko, kubandakanya iiglavu kunye neglavu.
2. Fumana indawo yoVavanyo loxinzelelo:
Chonga izibuko lovavanyo loxinzelelo kwinkqubo yempompo yomlilo. Oku ngokuqhelekileyo kubekwe kwicala lokukhupha lempompo.
3. Qhagamshela iSilinganisi soxinzelelo:
Sebenzisa izixhobo ezifanelekileyo ukudibanisa igeyiji yoxinzelelo kwizibuko lovavanyo. Qinisekisa itywina eliqinileyo ukuthintela ukuvuza.
4. Qalisa iMpompo yoMlilo:
Vula impompo yomlilo ngokwemiyalelo yomenzi. Qinisekisa ukuba inkqubo ilungisiwe kwaye ilungele ukusebenza.
5. Qwalasela ukuFunda koxinzelelo:
Nje ukuba impompo isebenze, jonga ubungakanani boxinzelelo kwigeyiji. Oku kuya kukunika uxinzelelo lokukhutshwa kwempompo.
6. Rekhoda uxinzelelo:
Qaphela uxinzelelo lokufunda kwiirekhodi zakho. Thelekisa uxinzelelo olufunekayo oluchazwe kuyilo lwenkqubo okanye imigangatho yeNFPA.
7. Jonga iiyantlukwano:
Ukuba kuyasebenza, jonga uxinzelelo kumazinga ahlukeneyo okuhamba (ukuba inkqubo ivumela) ukuqinisekisa ukuba ipompo isebenza ngokufanelekileyo kulo lonke uluhlu lwayo.
8. Vala iMpompo:
Emva kokuvavanya, vala ngokukhuselekileyo umpompo kwaye unqamule i-gauge yoxinzelelo.
9. Hlola imiba:
Emva kovavanyo, jonga isistim ukuba akukho nakuphi na ukuvuza okanye okungaqhelekanga okunokufuna ukuhoywa.
Iingqwalasela ezibalulekileyo:
Ukhuseleko Kuqala: Hlala ulandela iiprothokholi zokhuseleko xa usebenza ngeempompo zomlilo kunye neenkqubo zoxinzelelo.
Uvavanyo lwarhoqo: Ukuhlolwa rhoqo koxinzelelo kubalulekile ekugcineni ukuthembeka kwempompo yomlilo.
Yintoni Obona Buncinci boxinzelelo lweResidual yePump yoMlilo?
Uxinzelelo oluncinci olushiyekileyo lweempompo zomlilo ngokuqhelekileyo luxhomekeke kwiimfuno ezithile zenkqubo yokukhusela umlilo kunye neekhowudi zendawo. Nangona kunjalo, umgangatho oqhelekileyo kukuba ubuncinci boxinzelelo olushiyekileyo kufuneka lube ubuncinane be-20 psi (iipounds nge-intshi yesikwere) kwindawo yokukhupha i-hose ekude ngexesha leemeko zokuhamba okuphezulu.
Oku kuqinisekisa ukuba kukho uxinzelelo olwaneleyo lokuhambisa amanzi ngokufanelekileyo kwinkqubo yokucima umlilo, njengama-sprinklers okanye i-hoses.
Iimpompo ze-centrifugal ze-casing casing ezithe tyaba zihambelana ne-NFPA 20 kunye ne-UL yeemfuno zesicelo ezidweliswe kunye nezifakelo ezifanelekileyo zokubonelela ngamanzi kwiinkqubo zokukhusela umlilo kwizakhiwo, kwiifektri zezityalo kunye neeyadi.
