Chii chinonzi NFPA yePombi yeMvura yeMoto
Sangano reNational Fire Protection Association (NFPA) rine mitemo yakati wandei ine chekuita nemapombi emvura yemoto, kunyanya NFPA 20, inova "Standard for the Installation of Stationary Pombi dzekudzivirira moto." Mutemo uyu unopa gwara rekugadzira, kuisa, uye kugadzirisa mapombi emoto anoshandiswa mumasisitimu ekudzivirira moto.
Pfungwa huru kubva kuNFPA 20 dzinosanganisira:
Mhando dzeMapombi:
Inofukidza mhando dzakasiyana dzepombi dzekudzivirira moto, kusanganisira mapombi e centrifugal, mapombi e positive displacement, nezvimwewo.
Zvinodiwa pakuisa:
Inotsanangura zvinodiwa pakuiswa kwemapombi emoto, kusanganisira nzvimbo, kusvikika, uye kudzivirirwa kubva kuzvinhu zvakatipoteredza.
Kuedzwa uye Kugadziriswa:
NFPA 20 inotsanangura nzira dzekuedza uye nzira dzekugadzirisa kuti ive nechokwadi chekuti pombi dzemoto dzinoshanda zvakanaka kana zvichidikanwa.
Maitiro Ekushanda:
Mutemo uyu unosanganisira zvinodiwa nemapombi emoto kuti pave nechokwadi chekuti mvura inowanikwa zvakakwana uye simba rekudzivirira moto.
Magetsi:
Inogadzirisa kudiwa kwemagetsi akavimbika, kusanganisira masisitimu ekuchengetedza, kuitira kuti pombi dzemoto dzishande panguva dzenjodzi.
Kubva ku nfpa.org, inoti NFPA 20 inodzivirira hupenyu nepfuma nekupa zvinodiwa pakusarudza nekuisa mapombi kuitira kuti masisitimu ashande sezvaanoda kuti ape mvura yakakwana uye yakavimbika panguva yemoto.
Maitiro EkuverengaPombi yeMvura yeMotoKumanikidzwa?
Kuti uverenge kumanikidzwa kwepombi yemoto, unogona kushandisa fomura inotevera:
Fomura:
Kupi:
· P = Kumanikidzwa kwepombi mu psi (mapaundi pa sikweya inch)
· Q = Mwero wekuyerera kwemagaroni paminiti (GPM)
· H = Musoro wose une simba (TDH) mutsoka
· F = Kurasikirwa kwekukweshana mu psi
Matanho Ekuverenga Kumanikidzwa Kwepombi Yemoto:
Sarudza Mwero Wekuyerera (Q):
· Tsvaga mwero wekufamba kwemvura unodiwa pakudzivirira moto, unowanzo tsanangurwa muGPM.
Verenga Musoro Wese Unoshanduka (TDH):
· Musoro Unomira: Yera daro rakamira kubva patsime remvura kusvika panzvimbo yakakwirira yekubuditsa mvura.
· Kurasikirwa neFriction: Verenga kurasikirwa kwefriction mupombi uchishandisa machati kana mafomura ekurasikirwa nefriction (senge equation yaHazen-Williams).
· Kurasikirwa Nekukwira: Tarisa kana paine shanduko dziripo pakukwira kwenzvimbo.
[TDH= Musoro Wakasimba + Kurasikirwa Nekukweshana + Kurasikirwa Nekukwidza]
Verenga Kurasikirwa Kwekukweshana (F):
· Shandisa mafomula kana machati akakodzera kuti uone kurasikirwa kwekukweshana zvichienderana nehukuru hwepombi, kureba, uye mwero wekuyerera kwayo.
Batanidza Makoshero muForamu:
· Isa kukosha kweQ, H, naF mufomura kuti uverenge kumanikidzwa kwepombi.
Muenzaniso weKuverenga:
· Mwero weKuyerera (Q): 500 GPM
· Musoro Wese Unoshanduka (H): 100 tsoka
· Kurasikirwa nekukweshana (F): 10 psi
Kushandisa fomura:
Zvinhu Zvakakosha Kufunga nezvazvo:
· Iva nechokwadi chekuti kumanikidzwa kwakaverengerwa kunosangana nezvinodiwa nesystem yekudzivirira moto.
· Gara uchitarisa mitemo yeNFPA nemakodhi emunharaunda kuti uwane zvinodiwa nemirairo chaiyo.
· Bvunza mainjiniya wekudzivirira moto kana uine masisitimu akaomarara kana kana usina chokwadi nezvekuverenga kupi zvako.
Unotarisa Sei Kumanikidzwa Kwepombi Yemoto?
Kuti utarise kumanikidzwa kwepombi yemoto, unogona kutevera matanho aya:
1. Unganidza Midziyo Inodiwa:
Chiyero cheKudzvanyirira: Iva nechokwadi chekuti une chiyero cheKudzvanyirira chakagadziriswa chinogona kuyera huwandu hwesimba rinotarisirwa.
MaWrenches: Ekubatanidza geji kupombi kana pombi.
Zvishandiso zvekuchengetedza: Pfekai zvishandiso zvekuchengetedza zvakakodzera, kusanganisira magirovhosi nemagogorosi.
2. Tsvaga Nzvimbo Yekuongorora Kumanikidzwa:
Ziva nzvimbo yekuyedza kumanikidzwa iri papombi yemoto. Iyi inowanzo kuwanikwa parutivi rwepombi.
3. Batanidza Chiyero Chekudzvanya:
Shandisa zvinhu zvakakodzera kubatanidza pressure gauge ne test port. Iva nechokwadi chekuti wavhara zvakasimba kudzivirira kubuda kwemvura.
4. Tanga Pombi Yemoto:
Batidza pombi yemoto zvichienderana nemirairo yemugadziri. Iva nechokwadi chekuti sisitimu yacho yakagadzirira kushanda.
5. Tarisa Kuverengwa Kwekumanikidzwa:
Kana pombi yatanga kushanda, tarisa kuti simba rayo riri papi. Izvi zvinokupa simba rayo rekuburitsa simba.
6. Nyora Kumanikidzwa:
Cherechedza kuverenga kwekumanikidzwa kwezvinyorwa zvako. Enzanisa nekumanikidzwa kunodiwa kwakataurwa mukugadzirwa kwesystem kana muNFPA standards.
7. Tarisa kuti pane musiyano upi:
Kana zvichibvira, tarisa kumanikidzwa kwemvura pahuwandu hwakasiyana hwekuyerera kwemvura (kana sisitimu ichibvumira) kuti uve nechokwadi chekuti pombi inoshanda zvakanaka munzvimbo yayo yese.
8. Dzima Pombi:
Mushure mekuedza, dzima pombi zvakachengeteka uye bvisa pressure gauge.
9. Ongorora Matambudziko:
Mushure mekuedza, tarisai kuti muone kana paine kubuda kwemvura kana zvimwe zvinhu zvisina kumira zvakanaka zvingada kugadziriswa.
Zvinhu Zvakakosha Kufunga nezvazvo:
Kuchengetedza Kutanga: Gara uchitevedzera mitemo yekuchengetedza paunenge uchishanda nemapombi emoto uye masisitimu ane simba.
Kuongororwa Nguva Dzose: Kuongororwa nguva dzose kwekumanikidzwa kwakakosha kuti pombi yemoto irambe yakavimbika.
Chii Chinonzi Kumanikidzwa Kushoma Kwepombi Yemoto?
Kumanikidzwa kushoma kunosara kwemapombi emoto kunowanzoenderana nezvinodiwa zvesystem yekudzivirira moto nemakodhi emunharaunda. Zvisinei, chiyero chakajairika ndechekuti kumanikidzwa kushoma kunosara kunofanirwa kunge kuri 20 psi (mapaundi pa sikweya inch) panzvimbo yekubuditsa hosi iri kure zvakanyanya panguva yekuyerera kwakanyanya.
Izvi zvinoita kuti pave nekumanikidzwa kwakakwana kuti mvura iendeswe zvakanaka kumudziyo wekudzima moto, zvakaita sema sprinkler kana mapombi.
Mapombi e centrifugal akapatsanurwa anoenderana nezvinodiwa zveNFPA 20 neUL uye ane zvigadziko zvakakodzera zvekupa mvura kumasisitimu ekudzivirira moto muzvivakwa, mafekitori nemayadhi.
