Yintoni i-NFPA yempompo yamanzi emfazwe
Umbutho woKhuseleko lweSizwe wokuTyala (i-NFPA) unemigangatho eliqela ehambelana nempompo yamanzi omlilo, ikakhulu yi-NFPA 20, eyi "kumgangatho wokufakelwa kweempompo zesikhululo." Lo mgangatho ubonelela ngesikhokelo soyilo, ufakelo, kunye nokugcinwa kweempompo zomlilo ezisetyenziswa kwiinkqubo zokukhuselwa komlilo.
Amanqaku aphambili kwi-NFPA 20 kubandakanya:
Iindidi zempompo:
Ibandakanya iintlobo ezahlukeneyo zeUkulwa impompo.
Iimfuno zofakelo:
Icacisa iimfuno zokufakwa kweempompo zomlilo, kubandakanya indawo, ukufikeleleka, kunye nokukhusela izinto zokusingqongileyo.
Uvavanyo kunye noLondolozo:
Icacisa i-NFPA yeeprothokholi zokuvavanya kunye nendlela yolondolozo ukuqinisekisa ukuba iimpompo zomlilo zisebenza ngokufanelekileyo xa kufuneka njalo.
Imigangatho yokusebenza:
Owona mgangatho ubandakanya iikhrayitheriya zentsebenzo ezinokuthi zihlangane ukuqinisekisa ukuhanjiswa kwamanzi ngokwaneleyo kunye noxinzelelo kwimisebenzi yokucima umlilo.
Uncedo lwamandla:
Ithetha ngemfuneko yemithombo yombane ethembekileyo, kubandakanya iinkqubo ze-backup, ukuqinisekisa ukuba iimpompo zomlilo zisebenze ngexesha likaxakeka.
Ukusuka kwi-NFPA.org, i-NFPA ikhusela ubomi kunye nepropathi ngokubonelela ngeemfuno zokhetho kunye nokufakwa kweempompo ukuqinisekisa ukuba iinkqubo ziya kusebenza njengoko bekucwangcisiwe ukuhambisa amanzi kaxakeka.
Indlela yokubalaImpompo yamanzi omliloUxinzelelo?
Ukubala uxinzelelo lomlilo, ungasebenzisa le fomula ilandelayo:
Ifomula:
Phi:
I-PP PR = I-Pump yoxinzelelo kwi-PSI (iipawundi nganye kwi-intshi)
Inqanaba lokuhamba kwiilitha ngomzuzu (GPM)
I-· · h = i-· h = intloko ye-dyh) ezinyaweni
· Ff = ilahleko ye-facring kwi-pSI
Amanyathelo okubala uxinzelelo lomlilo:
Chonga inqanaba lokuhamba (q):
· Ukucenga inqanaba lokuhamba kwemfuno efunekayo kwiNkqubo yakho yokukhusela umlilo, ihlala ichazwe kwi-GPM.
Bala intloko yentloko ye-tenamic (i-TDH):
Intloko ye-statric: ilinganisa umgama othe nkqo ukusuka kumthombo wamanzi ukuya kwelona nqaku liphezulu lokukhupha.
Ilahleko yentsebenzo: Bala ilahleko yefreyiti kwinkqubo yokuthambisa usebenzisa iitshathi zedrafti okanye iifomula (njenge-hazen-williams equation).
Ilahleko ye-Akhawunti: malunga naluphi na utshintsho olwenziweyo kwinkqubo.
[I-TDH = I-Static Cles + Ilahleko ye-finctions + ilahleko yokuphakamisa]
Bala ilahleko yefreyiti (f):
Ifomula efanelekileyo okanye iitshathi zokufumanisa ilahleko yokuxinana ngokusekwe kubungakanani bombhobho, ubude, kunye nenqanaba lokuhamba.
I-plug amaxabiso kwifomula:
Ukufakelwa kwexabiso le-Q, h, kunye ne-F kwifomula ukubala uxinzelelo lwempompo.
Umzekelo ubalo:
Ixabiso lokuhamba (q): 500 gpm
Intloko ye-· tos · imemic (H): iinyawo ezili-100
Ilahleko yempungutye (f): 10 PSI
Sebenzisa ifomula:
Ukuqwalaselwa kubalulekile:
· Q Qinisekisa ukuba uxinzelelo olubaliweyo luhlangabezana neemfuno zenkqubo yokukhusela umlilo.
Ukuhlala ujonge imigangatho ye-NFPA kunye neekhowudi zengingqi kwiimfuno ezithile kunye nezikhokelo.
Injini yokunxibelelana nenjini yokhuseleko lomlilo kwiinkqubo ezintsonkothileyo okanye ukuba awuqinisekanga malunga nokubala.
Ujonga njani uxinzelelo lwempompo yomlilo?
Ukujonga uxinzelelo lwempompo yomlilo, ungalandela la manyathelo:
1. Qokelela izixhobo eziyimfuneko:
I-Gauge Geuge: Qinisekisa ukuba une-gagetid yoxinzelelo enokulinganisa uluhlu loxinzelelo olulindelekileyo.
Ukonakaza: ukudibanisa igeji kwimpompo okanye ukunyibilika.
Igiya yokhuseleko: nxiba igiya efanelekileyo yokhuseleko, kubandakanya neegloves kunye neegogo.
2. Khangela izibuko lovavanyo loxinzelelo:
Chonga izibuko lovavanyo kwi-pump ye-pump. Oku kuhlala kubekwe kwicala lokukhupha impompo.
3. Qhagamshela igeji yoxinzelelo:
Sebenzisa izinto ezifanelekileyo zokuqhagamshela igeji yoxinzelelo kwizibuko lovavanyo. Qinisekisa itywina eliqinileyo ukuthintela ukuvuza.
4. Qala impompo yomlilo:
Vula impompo yomlilo ngokwemiyalelo yomenzi. Qinisekisa ukuba inkqubo igqityiwe kwaye ilungele ukusebenza.
5. Qwalasela ukufundwa koxinzelelo:
Nje ukuba impompo iyasebenza, jonga ukufundwa koxinzelelo kwigeji. Oku kuya kukunika uxinzelelo lokukhupha impompo.
6. Rekhoda uxinzelelo:
Qaphela ukufundela uxinzelelo kwiirekhodi zakho. Thelekisa noxinzelelo olufunekayo oluchazwe kumgangatho wenkqubo okanye kwi-NFP.
7. Jonga umahluko:
Ukuba kuyasebenza, jonga uxinzelelo kwiirhafu ezahlukeneyo zokuhamba (ukuba inkqubo ivumela) ukuqinisekisa ukuba impompo isebenza ngokufanelekileyo kuluhlu lwayo.
8. Vala impompo:
Emva kovavanyo, vala ngokukhuselekileyo impompo kwaye unqamle igeji yoxinzelelo.
9. Vavanya imiba:
Emva kovavanyo, jonga inkqubo yokuvuza okanye ukungabi nangqondo ekusenokufuna ingqalelo.
Ukuqwalaselwa kubalulekile:
Ukhuseleko kuqala: Soloko ulandela iiprothokholi zokhuseleko xa usebenza neempompo zomlilo kunye neenkqubo ezihlaziyiweyo.
Uvavanyo rhoqo: Iitsheki zoxinzelelo rhoqo zibalulekile ekugcineni ukuthembeka kwempompo yomlilo.
Yeyiphi eyona ntshukumo ishiyekileyo ye-pump yomlilo?
Owona mvuzo uphambili wentsalela ye-pumps yomlilo ngokweemfuno ezithile zenkqubo yokukhusela umlilo kunye neekhowudi zasekhaya. Nangona kunjalo, umgangatho oqhelekileyo kukuba olona xinzelelo lwentsalela lentsalela kufuneka ubuncinci bube zii-20 ze-PSI
Oku kuqinisekisa ukuba kukho uxinzelelo olwaneleyo lokuhambisa amanzi ngempumelelo kwinkqubo yokucinezelwa komlilo, njenge-spanklers okanye iimpuphu.
