Chii chinonzi nfpa yemoto wemoto pombi
Iyo National Fire Dziviriro Kusangana Iyi yakaganhurika inopa nhungamiro yekugadzira, kuisirwa, uye kuchengetedza kwemapepa emoto kunoshandiswa mune masisitimu ekudzivirira moto.
ZVINOKOSHA ZVINOKOSHA kubva kuNFPA 20 zvinosanganisira:
Mhando dzeMapepa:
Inovhara mhando dzakasiyana siyana dzemoto kurwisa pombi, kusanganisira centrifugal pumps, madhiri akanaka ekudzingwa, uye vamwe.
Kuisa zvinodiwa:
Izvo zvinobuda zvinodiwa zvekuisa kwemapuru emoto, kusanganisira nzvimbo, kuwanikwa, uye kuchengetedzwa pazvinhu zvezvakatipoteredza.
Kuyedzwa nekugadzirisa:
NFPA 20 inotsanangura protocol uye maitiro ekugadzirisa kuti uve nechokwadi chekuti mapapipi emoto anoshanda zvinobudirira pazvinodiwa.
Maitiro Ekuita:
Iyo standard inosanganisira maitiro ekuita kuti mapumla emoto anofanirwa kusangana kuti ave nechokwadi chekuwanikwa zvakakwana uye kumanikidzwa kwemidziyo yemoto.
Magetsi:
Inotaura nezve kukosha kwezvinhu zvakavimbika maseru, kusanganisira backup system, kuve nechokwadi chekuti mapepa emoto anogona kushanda panguva yemanyowa.
Kubva kuNfpa.org, Inotiza NFPA 20 Nekupa Izvo Zvinodikanwa Zvekusarudzwa uye Kuiswa Kwemapombi kuti zviitwe sekupa kwemvura yakakwana uye yakavimbika mvura inowanikwa mumamiriro ekunze emoto.
Maitiro EkuverengaPombi yemvura yemvuraKumanikidzwa?
Kuti uverenge moto pombi dzvinyiriro, unogona kushandisa iyo inotevera formula:
Formula:
Kupi:
· P
· Im = kuyerera huwandu mumarita paminiti (GPM)
H = Yakazara Dynamic Musoro (TDH) tsoka
· F = kupokana kurasikirwa muPSI
Matanho ekuverenga moto pombi dzvinyiriro:
Sarudza kuyerera kuyerera (Q):
Rwazisa iyo inodikanwa kuyerera chiyero cheyako moto yekudzivirira system, kazhinji inotsanangurwa muGPM.
Kuverenga kwakazara kwakazara musoro (TDH):
· Static misoro: kuyera iyo yakatwasuka kure kubva kune iyo mvura sosi kune yakakwirira nzvimbo yekuburitsa.
Forport kurasikirwa: Verenga kurasikirwa kwekupokana muPIPing System uchishandisa Friction Kurasikirwa Kwechati kana mafomu (kunge maHazalas-Williams equation).
· Elms kurasikirwa: Akaunti kune chero chero shanduko yekuchinja muhurongwa.
[TDH = static musoro + kupokana kurasikirwa + kusimudza kurasikirwa]
Verenga kurasikirwa kwekurasikirwa (F):
Shandisa mafomu akakodzera akakodzera kana machati ekuona kurasikirwa kwekupokana zvichienderana nehukuru hwe pombi, kureba, uye kuyerera.
Plug kukosha mune formula:
· Tsanga kukosha kwe q, h, uye f mune formula yekuverengera kudzvinyirira pombi.
Kuverenga muenzaniso:
· Flow Rate (Q): 500 GPM
· Zvemusoro Dynamic Musoro (H): 100 tsoka
· Forption kurasikirwa (F): 10 PSI
Uchishandisa formula:
Kukosha Kukurukurirana:
· Simbisa kuti kudzvanywa kwekuverengerwa kunosangana nezvinodiwa zveiyo fire dziviriro system.
· Zvakajairika zvinoreva nezve nfpa zviyero uye makodhi emunharaunda nezvakananga zvinodiwa uye nhungamiro.
· Tarisa uone neinjiniya yekuchengetedza moto kune yakaoma masisitimu kana iwe usina chokwadi nezve chero kuverenga.
Unoongorora sei moto pombi yekumanikidza?
Kuti utarise kudzvinyirira moto, unogona kutevera matanho aya:
1. Unganidza zvinodiwa michina:
Dzvinyiriro Gauge: Ita shuwa kuti iwe unyorwe kumanikidzwa kugera iyo inogona kuyera iyo inotarisirwa kumanikidza mhando.
Mapurasiti: yekubatanidza iyo geji kune pombi kana kupomba.
Kuchengetedza Gear: Pfeka yakakodzera yekuchengetedza giya, kusanganisira magurovhosi uye goggles.
2. Tsvaga iyo yekumanikidza bvunzo chiteshi:
Ziva chiteshi chekumanikidza chekumanikidza pane iyo moto pombi system. Izvi zvinowanzoitika pane discharge rutivi rwepombi.
3. Batanidza kumanikidza Gauge:
Shandisa zvakakodzera zvakakodzera kubatanidza kudzvinyirira geji kune iyo bvunzo chiteshi. Ita shuwa chisimbiso chakasimba kudzivirira kubhururuka.
4. Kutanga pombi yemoto:
Vhura pombi yemoto zvichienderana nemirairo yemugadziri. Ita shuwa kuti hurongwa hunorongwa uye hwakagadzirira kushanda.
5. Chengetedza kuverenga kwekumanikidza:
Kana pombi iri kumhanya, chengetedza kumanikidzwa kuverenga pane geji. Izvi zvinokupa iyo yekudzvinyirira yekudzvinyirira yepombi.
6. Rekodha kumanikidzwa:
Cherekedza kudzvinyirira kuverenga kwezvakanyorwa zvako. Enzanisa nayo kune inodiwa kudzvanywa yakatsanangurwa mune iyo system dhizaini kana NFPA zviyero.
7. Tarisa kusiyanisa:
Kana zvichishanda, tarisa kumanikidzwa kune dzakasiyana dzinoyerera mitengo (kana iyo system ichibvumira) kuve nechokwadi chekuti pombi inoshanda zvinokonzeresa huwandu hwayo.
8. Vhara pasi pombi:
Mushure mekuyedza, kuvhara zvakachengeteka pombi uye kudzima kudzvinyirira geji.
9. Ongorora Zvenyaya:
Mushure mekuongororwa, kuongorora hurongwa hwemhando ipi neipi yekukora kana kusanzwisisika kungada kutariswa.
Kukosha Kukurukurirana:
Chengetedzo Kutanga: Gara uchitevera protocols yekuchengetedza kana uchishanda nemapepa emoto uye masisitimu akatsamwa.
Kugara uchiedza: Kugara uchimanikidzwa macheki zvakakosha kuti uchengetedze kuvimbika kweparapu yemoto.
Ndeipi kushoma kusara kwekumanikidza kwepombi yemoto?
Iko kusara kwakasiyana-siyana kumanikidzwa kwemoto kazhinji kunoenderana nezvinodiwa zvekudzivirira kwemoto uye makodhi emuno. Nekudaro, chiyero chakajairika ndechekuti kushoma kwakasiyana kudzvanywa kunofanirwa kunge kuri kwe20 Psi (mapaundi pane mraba inch) panguva yekureba kure kwehose panguva yekubuda mukati menguva yekuyerera.
Izvi zvinovimbisa kuti kune kumanikidzwa kwakaringana kuti ubudirire kununura mvura kune iyo Fire Sroupression System, sekusasimuka kana hoses.
Akasangana akapatsanura casing centres centrilu pumps ane nfpa 20 uye ul yakanyorwa application zvinodiwa uye ine yakakodzera yekupa mvura kune zvivakwa zvivakwa, mafekitori zvidyarwa uye mayadhi.
