Izindaba - Yini i-NFPA yepompo yamanzi omlilo? Ungabala kanjani umfutho wepompo wamanzi omlilo?

Yini i-NFPA yepompo yamanzi omlilo

I-National Fire Protection Association (NFPA) inamazinga amaningana aphathelene namaphampu wamanzi omlilo, ngokuyinhloko i-NFPA 20, okuyi- "standard yokufakwa kwamaphampu okuvikelwa umlilo." Leli Zinga linikeza imihlahlandlela yokuqamba, ukufakwa, kanye nokunakekelwa kwamaphampu omlilo asetshenziswa ezinhlelweni zokuvikela umlilo.

Amaphuzu asemqoka avela ku-NFPA 20 afaka:

Izinhlobo zamaphampu:

Ihlanganisa izinhlobo ezahlukahlukene zeAmaphampu okulwa nomlilo, kufaka phakathi amaphampu we-centrifugal, amaphampu abuhlungu, nabanye.

Izidingo zokufaka:

Ibonisa izidingo zokufakwa kwamaphampu omlilo, kufaka phakathi indawo, ukufinyeleleka, nokuvikelwa ezimweni zemvelo.

Ukuhlola nokulungisa:

I-NFPA 20 icacisa amaphrothokholi wokuhlola kanye nezindlela zokulungisa ukuqinisekisa ukuthi amaphampu omlilo asebenza ngempumelelo lapho kudingeka.

Amazinga okusebenza:

Izinga lifaka phakathi izindlela zokusebenza ukuthi amaphampu omlilo kufanele ahlangane ukuze aqinisekise ukuhlinzekwa kwamanzi nengcindezi yemisebenzi yokucisha umlilo.

Ukunikezwa kwamandla kagesi:

Ikhuluma ngesidingo semithombo yamandla ethembekile, kufaka phakathi izinhlelo zokusekelayo, ukuqinisekisa ukuthi amaphampu omlilo angasebenza ngesikhathi sezimo eziphuthumayo.

Kusuka ku-NFPA.ORG, ithi i-NFPA 20 ivikela impilo nempahla ngokunikeza izidingo zokukhethwa kokukhethwa nokufakwa kwamaphampu ukuze kuqinisekiswe ukuthi izinhlelo zizosebenza njengoba kuhloswe ukuthi zilethe izinto eziphuthumayo zomlilo.

Ungalibala KanjaniIphampu yamanzi yomliloIngcindezi?

Ukubala ingcindezi yepompo yomlilo, ungasebenzisa ifomula elandelayo:

Ifomula:

Lapho:

· P = ingcindezi yepompo ku-PSI (amakhilogremu ngakunye kwe-intshi)

· Q = isilinganiso sokugeleza ngamalitha ngomzuzu (GPM)

· H = Ikhanda elinamandla elinamandla (TDH) ezinyaweni

· F = ukulahleka kokungqubuzana ku-PSI

Izinyathelo zokubala ingcindezi yepompo yomlilo:

Thola isilinganiso sokugeleza (Q):

· Thola isilinganiso sokugeleza esidingekayo sohlelo lwakho lokuvikela umlilo, oluvame ukucaciswa ku-GPM.

Bala i-Graxic Head (TDH):

I-Static Head: Linganisa ibanga elimile kusuka kumthombo wamanzi uye endaweni ephakeme kakhulu yokukhishwa.

· Ukulahleka kwe-Chark: Bala ukulahleka kwezingxabano ohlelweni lwamapayipi usebenzisa amashadi wokulahleka noma amafomula (njenge-hazen-williams equation).

Ukulahleka kokuphakama: I-akhawunti yanoma yiziphi izinguquko eziphakeme ohlelweni.

[TDH = Ikhanda le-Static + Ukulahleka Kwezingxabano + Ukulahleka kokuphakama]

Bala ukulahleka kwe-Frity (F):

· Sebenzisa amafomula afanele noma amashadi okuthola ukulahleka kwezingxabano ngokususelwa kusayizi wepayipi, ubude, kanye nezinga lokugeleza.

Ama-plug amanani efomula:

· Faka esikhundleni amanani we-Q, H, kanye no-F efomula ukubala ingcindezi yempompo.

Ukubalwa kwesibonelo:

· Inani lokugeleza (Q): 500 gpm

· Ikhanda elinamandla (h): amamitha ayi-100

· Ukulahleka kwe-Chark (F): 10 PSI

Kusetshenziswa ifomula:

Ukucatshangelwa Okubalulekile:

· Qinisekisa ukuthi ingcindezi ebaliwe ihlangabezana nezidingo zohlelo lokuvikela umlilo.

Hlala ubhekisa kumazinga we-NFPA namakhodi endawo ngezidingo ezithile kanye nemihlahlandlela.

· Concer unjiniyela wokuvikela umlilo wezinhlelo eziyinkimbinkimbi noma uma ungaqiniseki nganoma yikuphi ukubalwa.

Uhlola kanjani ukucindezela kwepompo yomlilo?

Ukuhlola ingcindezi yempompo yomlilo, ungalandela lezi zinyathelo:

1. Hlanganisa imishini edingekayo:

I-Pressure Gauge: Qinisekisa ukuthi une-cauge yengcindezi evuthayo engalinganisa uhla lwezingcindezi ezilindelekile.

Ama-Wreds: Ngokuxhuma i-gauge ephampu noma epayipi.

Igiya lokuphepha: Gqoka amagiya okuphepha afanele, kufaka phakathi amagilavu kanye nama-goggles.

2. Thola i-Pressure Test Port:

Khomba imbobo yokuhlola ingcindezi ohlelweni lwepompo yomlilo. Lokhu kuvame ukuba khona ohlangothini lwepompo.

3. Xhuma igeyimu yokucindezela:

Sebenzisa ukufakwa okufanele ukuxhumanisa ingcindezi yegeji ethekwini lokuhlola. Qinisekisa uphawu oluqinile ukuvikela ukuvuza.

4. Qala iphampu yomlilo:

Vula iphampu yomlilo ngokuya ngemiyalo yomenzi. Qinisekisa ukuthi uhlelo lubhaliwe futhi lulungele ukusebenza.

5. Bheka ukufundwa kwengcindezi:

Lapho nje ipompo isebenza, qaphela ukufundwa kwengcindezi egameni. Lokhu kuzokunikeza ingcindezi yokukhipha yepompo.

6. Qopha ingcindezi:

Qaphela ukufundwa kwengcindezi kwamarekhodi akho. Qhathanisa nengcindezi edingekayo echazwe ekwakhiweni kwesistimu noma kumazinga we-NFPA.

7. Bheka ukuhlukahluka:

Uma kusebenza, hlola ingcindezi ngamanani ahlukene wokugeleza (uma uhlelo luvumela) Ukuqinisekisa ukuthi iphampu lisebenza ngempumelelo kulo lonke uhla lwayo.

8. Cisha iphampu:

Ngemuva kokuhlola, vala ngokuphepha ipompo bese unqamula igeji yokucindezela.

9. Hlola izindaba:

Ngemuva kokuhlola, hlola uhlelo nganoma yikuphi ukuvuza noma ukungahambi kahle okungadinga ukunakwa.

Ukucatshangelwa Okubalulekile:

Okokuphepha kuqala: Landela amaphrothokholi wokuphepha lapho usebenza ngamaphampu omlilo nezinhlelo ezicindezelwe.

Ukuhlolwa njalo: Ukuhlolwa kwengcindezi ejwayelekile kubalulekile ukuze kugcinwe ukwethenjwa kwepompo yomlilo.

Yikuphi ukucindezela okusele okusele kwephampu yomlilo?

Ingcindezi esele esele yamaphampu omlilo ngokuvamile incike kwizidingo ezithile zohlelo lokuvikela umlilo namakhodi endawo. Kodwa-ke, okuyindinganiso ejwayelekile ukuthi ingcindezi eyinsalela ephansi kufanele okungenani ibe ngu-20 psi (amakhilogremu nge-inch ye-outch eyi-hose endaweni ephezulu ye-hose ngesikhathi semibandela ephezulu yokugeleza.

Lokhu kuqinisekisa ukuthi kunengcindezi eyanele yokuletha ngempumelelo amanzi ohlelweni lokucindezela umlilo, njengama-sprinklers noma ama-hoses.
