Wararka - Waa maxay NFPA ee matoorka biyaha dabka? Sida loo xisaabiyo cadaadis biyo dabka dabka ah?

Ururka Ilaalinta Qaranka ee Qaranka (NFPA) waxay leedahay heerar badan oo ku saabsan matoorka biyaha dabka, ugu horreyndhow, oo ah "Heerka" Standard rakibaadda matoorrada sadarka ee ilaalinta dabka ee ilaalinta dabka. " Heerkan wuxuu bixiyaa tilmaamo loogu talagalay qaabeynta, rakibidda, iyo dayactirka bambooyinka dabka ee loo isticmaalo nidaamyada ilaalinta dabka.

Qodobbada Muhiimka ah ee NFPA 20 waxaa ka mid ah:

Noocyada bambooyinka:

, oo ay ku jiraan bambooyinka centrifugal, bambooyin barakac ah oo barakaca ah, iyo kuwa kale.

Shuruudaha rakibaadda:

Waxay qeexeysaa shuruudaha rakibidda bambooyinka dabka, oo ay kujirto goobta, marin u helka, iyo ka ilaalinta arrimaha deegaanka.

NFPA 20-aad waxay cayimaysaa tijaabada borotokoolka iyo dhaqamada dayactirka si loo hubiyo in matoorrada dabka ay shaqeeyaan si hufan markii loo baahdo.

Heerarka Waxqabadka:

Heerka waxaa ka mid ah shuruudaha waxqabadka in matoorrada dabka ay la kulmaan si loo hubiyo sahay biyo ku filan iyo cadaadis ku filan hawlgallada dab-damiska.

Sida loo xisaabiyoBiyuhu dab damisCadaadis?

Halkee:

· H = madaxa guud ee firfircoon (TDH) cagaha

· F = kala-baxa lumay ee PSI

Tallaabooyinka lagu xisaabinayo cadaadiska matoorka dabka:

Go'aaminta heerka qulqulka (Q):

Xisaabi wadarta guud ee firfircoon (TDH):

· Madaxa toosan: cabir masaafada toosan ee isha biyaha ilaa meesha ugu sarreeya ee dheecaanka.

· Ka-saaridda khasaaraha: Koontada wixii isbeddel ah ee kor u kaca ee nidaamka.

[TDH = madaxa Static + khasaaro jahwareer ah

Xisaabinta lumitaanka jajabka (f):

· Isticmaal qaaciidooyinka ku habboon ama jaantusyada si aad u go'aamiso luminta khatarta ku saleysan cabirka tuubbada, dhererka, iyo heerka socodka.

Ku xir qiimayaasha qaaciddada:

· Ku beddelo qiimayaasha Q, H, iyo F ee caanobooraha si loo xisaabiyo cadaadiska bamka.

· Sicirka qulqulka (Q): 500 gpm

· Wadarta guud ee firfircoon (H): 100 cagood

Tixgelinno muhiim ah:

· Had iyo jeer tixraac Heerarka NFPA iyo Xeerarka maxalliga ah ee shuruudaha gaarka ah iyo tilmaamaha.

Sideed u hubisaa cadaadiska bamka dabka?

Si aad u hubiso cadaadiska bamka dabka, waxaad raaci kartaa talaabooyinkan:

Qulqulka: loogu talagalay isku xirka cabirka bamka ama tuubada.

Qalabka badbaadada: Xiro qalabka nabdoonaanta ee ku habboon, oo ay ku jiraan galoofyada iyo gogosha.

2. Meel ku ogow dekada Imtixaanka Cadaadiska:

3. Ku xir cabirka cadaadiska:

U adeegso qalabka ku habboon si aad ugu xirto cabirka cadaadiska ee dekada tijaabada ah. Hubso shaabad adag si looga hortago daadasha.

4. Bilow matoorka dabka:

6. Qor cadaadiska:

Xusuusnow cadaadiska cadaadiska ee diiwaankaaga. Isbarbar dhig cadaadiska loo baahan yahay ee lagu qeexay qaabeynta nidaamka ama heerarka NFPA.

9. Kor u qaad arrimaha:

Tijaabada ka dib, baar nidaamka wixii daadanaya ama aan caadi ahayn oo u baahan kara feejignaan.

Tixgelinno muhiim ah:

Waa maxay cadaadiska ugu yar ee haraaga ah ee matoorka dabka?

The minimum residual pressure for fire pumps typically depends on the specific requirements of the fire protection system and local codes. Si kastaba ha noqotee, heerka caadiga ah ayaa ah in cadaadiska ugu yar ee haraaga ahi ay noqon karto ugu yaraan 20 psi (pound halkii inji labajibbaarane) markii ugu badan ee tuubada ugu fog ee tuubada ugu badan.

Tani waxay xaqiijineysaa in ay jirto cadaadis ku filan oo si wax ku ool ah u gaarsiiya biyaha nidaamka xakamaynta dabka, sida rucubleyaasha ama tuubooyinka tuubooyinka.

Jid-jeexjeexyada toosan ee matoorrada Centrifugal waxay u hoggaansamayaan NFPA 20 iyo shuruudaha dalabka ee ku taxan ee ku taxan bixinta biyaha ee nidaamyada ilaalinta dabka ee dhismayaasha, warshadaha dhirta iyo yaysyada dhirta.

Baaxadda sahayda: mashiinka wadista matoorka dabka + xakameynta gunta + jockey bamka
