Kodi NFPA ya Pampu Yothira Madzi a Moto ndi Chiyani?
Bungwe la National Fire Protection Association (NFPA) lili ndi miyezo ingapo yokhudzana ndi mapampu amadzi amoto, makamaka NFPA 20, yomwe ndi "Muyezo Wokhazikitsa Mapampu Okhazikika Oteteza Moto." Muyezo uwu umapereka malangizo opangira, kukhazikitsa, ndi kusamalira mapampu amoto omwe amagwiritsidwa ntchito m'makina oteteza moto.
Mfundo zazikulu kuchokera ku NFPA 20 ndi izi:
Mitundu ya Mapampu:
Zimakhudza mitundu yosiyanasiyana yamapampu ozimitsa moto, kuphatikizapo mapampu a centrifugal, mapampu osuntha bwino, ndi zina.
Zofunikira pa Kukhazikitsa:
Imafotokoza zofunikira pakuyika mapampu ozimitsa moto, kuphatikizapo malo, kupezeka mosavuta, komanso chitetezo ku zinthu zachilengedwe.
Kuyesa ndi Kusamalira:
NFPA 20 imafotokoza njira zoyesera ndi njira zosamalira kuti zitsimikizire kuti mapampu ozimitsa moto amagwira ntchito bwino pakafunika kutero.
Miyezo Yogwirira Ntchito:
Muyezowu ukuphatikizapo miyezo yogwirira ntchito yomwe mapampu ozimitsa moto ayenera kukwaniritsa kuti atsimikizire kuti pali madzi okwanira komanso mphamvu zokwanira zozimitsira moto.
Magetsi:
Ikufotokoza kufunika kwa magwero odalirika amagetsi, kuphatikizapo makina osungira, kuti zitsimikizire kuti mapampu ozimitsa moto amatha kugwira ntchito panthawi yamavuto.
Kuchokera ku nfpa.org, imati NFPA 20 imateteza moyo ndi katundu mwa kupereka zofunikira pakusankha ndi kukhazikitsa mapampu kuti zitsimikizire kuti makina azigwira ntchito monga momwe amafunira kuti apereke madzi okwanira komanso odalirika pakagwa moto.
Momwe MungawerengerePampu ya Madzi a MotoKupanikizika?
Kuti muwerengere kuthamanga kwa pampu yamoto, mungagwiritse ntchito njira iyi:
Fomula:
Kumene:
· P = Kupanikizika kwa pompu mu psi (mapaundi pa inchi imodzi)
· Q = Kuchuluka kwa madzi m'magaloni pamphindi (GPM)
· H = Mutu wonse wamphamvu (TDH) m'mapazi
· F = Kutayika kwa kukangana mu psi
Njira Zowerengera Kupanikizika kwa Pampu Yoyaka Moto:
Dziwani Kuchuluka kwa Kuyenda (Q):
· Dziwani kuchuluka kwa madzi komwe kumafunika pa makina anu oteteza moto, omwe nthawi zambiri amatchulidwa mu GPM.
Kuwerengera Mutu Wonse Wosintha (TDH):
· Mutu Wosasunthika: Yesani mtunda woyima kuchokera ku gwero la madzi mpaka pamalo okwera kwambiri otulutsira madzi.
· Kutayika kwa Mphambano: Werengerani kutayika kwa Mphambano mu dongosolo la mapaipi pogwiritsa ntchito matchati kapena ma formula otayika kwa Mphambano (monga Hazen-Williams equation).
· Kutaya Kukwera: Lembani kusintha kulikonse kwa kukwera m'dongosolo.
[TDH= Mutu Wosasunthika + Kutayika kwa Mikangano + Kutayika kwa Kukwezeka]
Werengerani Kutayika kwa Kukangana (F):
· Gwiritsani ntchito njira zoyenera kapena matchati kuti mudziwe kutayika kwa kukangana kutengera kukula kwa chitoliro, kutalika, ndi kuchuluka kwa madzi.
Ikani Ma Values mu Fomula:
· Sinthani ma values a Q, H, ndi F mu fomula kuti muwerengere kuthamanga kwa pampu.
Kuwerengera Chitsanzo:
· Kuthamanga kwa Mayendedwe (Q): 500 GPM
· Mutu Wonse Wosinthasintha (H): 100 mapazi
· Kutaya kwa Mkangano (F): 10 psi
Kugwiritsa ntchito fomula iyi:
Mfundo Zofunika Kuziganizira:
· Onetsetsani kuti kuthamanga komwe kwawerengedwa kukukwaniritsa zofunikira za makina otetezera moto.
· Nthawi zonse tsatirani miyezo ya NFPA ndi ma code am'deralo kuti mudziwe zofunikira ndi malangizo enaake.
· Funsani mainjiniya woteteza moto kuti akuthandizeni pa makina ovuta kapena ngati simukudziwa bwino za mawerengedwe aliwonse.
Kodi Mumayesa Bwanji Kupanikizika kwa Pampu Yoyaka Moto?
Kuti muwone kuthamanga kwa pampu yozimitsa moto, mutha kutsatira izi:
1. Sonkhanitsani Zida Zofunikira:
Chiyeso cha Kupanikizika: Onetsetsani kuti muli ndi chiyeso choyezera kuthamanga chomwe chingathe kuyeza kuchuluka kwa kuthamanga komwe kumayembekezeredwa.
Ma Wrenches: Olumikizira geji ku pampu kapena mapaipi.
Zida Zotetezera: Valani zida zoyenera zotetezera, kuphatikizapo magolovesi ndi magalasi.
2. Pezani Doko Loyesera Kupanikizika:
Dziwani malo oyesera kuthamanga kwa mpweya pa makina ozimitsa moto. Nthawi zambiri izi zimakhala mbali yotulutsira mpweya pamakina ozimitsa moto.
3. Lumikizani Chiyeso cha Kupanikizika:
Gwiritsani ntchito zida zoyenera kulumikiza choyezera kuthamanga ndi doko loyesera. Onetsetsani kuti mwatseka mwamphamvu kuti musatuluke madzi.
4. Yambitsani Pampu Yozimitsa Moto:
Yatsani pampu yozimitsira moto motsatira malangizo a wopanga. Onetsetsani kuti makinawo ali okonzeka kugwira ntchito.
5. Yang'anirani Kuwerenga kwa Kupanikizika:
Pampu ikayamba kugwira ntchito, yang'anani kuchuluka kwa kuthamanga kwa madzi pa gauge. Izi zikupatsani mphamvu yotulutsa madzi pa pampu.
6. Lembani Kupanikizika:
Onani kuchuluka kwa kupanikizika komwe kumawerengedwa. Yerekezerani ndi kupanikizika komwe kumafunika komwe kwatchulidwa mu kapangidwe ka makina kapena miyezo ya NFPA.
7. Yang'anani Zosiyanasiyana:
Ngati n'kotheka, yang'anani kuthamanga kwa madzi pamlingo wosiyanasiyana (ngati makinawo alola) kuti muwonetsetse kuti pampu ikugwira ntchito bwino pamlingo wake wonse.
8. Zimitsani Pampu:
Mukamaliza kuyesa, tsekani pampu mosamala ndikuchotsa choyezera kuthamanga.
9. Yang'anani Mavuto:
Mukamaliza kuyesa, yang'anani makinawo kuti muwone ngati pali kutuluka kapena zolakwika zilizonse zomwe zingafunike kusamalidwa.
Mfundo Zofunika Kuziganizira:
Chitetezo Choyamba: Nthawi zonse tsatirani njira zotetezera mukamagwiritsa ntchito mapampu ozimitsa moto ndi makina opanikizika.
Kuyesa Kwanthawi Zonse: Kuyang'ana kuthamanga kwa madzi nthawi zonse n'kofunika kwambiri kuti pampu yozimitsira moto ikhale yodalirika.
Kodi Kupanikizika Kochepa Kotsalira kwa Pampu Yozimitsa Moto Ndi Chiyani?
Kuthamanga kochepa kotsalira kwa mapampu oyaka moto nthawi zambiri kumadalira zofunikira za makina otetezera moto ndi ma code am'deralo. Komabe, muyezo wodziwika bwino ndi wakuti kuthamanga kochepa kotsalira kuyenera kukhala osachepera 20 psi (mapaundi pa inchi imodzi) pamalo otulukira payipi akutali kwambiri panthawi yoyenda kwambiri.
Izi zimatsimikizira kuti pali mphamvu yokwanira yoperekera madzi bwino ku makina ozimitsira moto, monga zothira madzi kapena mapaipi.
Mapampu a centrifugal opangidwa mopingasa amatsatira zofunikira za NFPA 20 ndi UL komanso zida zoyenera zoperekera madzi ku makina oteteza moto m'nyumba, mafakitale ndi m'mabwalo.
