Nkhani - Kodi NFPA Ya Pampu Yamadzi Amoto Ndi Chiyani? Momwe Mungawerengere Kuthamanga kwa Pampu ya Madzi a Moto?

Kodi NFPA Ya Pampu Yamadzi Amoto Ndi Chiyani

National Fire Protection Association (NFPA) ili ndi miyezo ingapo yokhudzana ndi mapampu amadzi amoto, makamaka NFPA 20, yomwe ndi "Standard for the Installation of Stationary Pump for Fire Protection." Mulingo uwu umapereka malangizo opangira, kukhazikitsa, ndi kukonza mapampu ozimitsa moto omwe amagwiritsidwa ntchito poteteza moto.

Mfundo zazikuluzikulu za NFPA 20 ndi izi:

Mitundu ya Mapampu:

Zimakhudza mitundu yosiyanasiyana yamapampu ozimitsa moto, kuphatikizapo mapampu apakati, mapampu abwino osamutsidwa, ndi zina.

Zofunikira pakuyika:

Ikufotokoza zofunikira pakuyika mapampu ozimitsa moto, kuphatikiza malo, kupezeka, ndi chitetezo kuzinthu zachilengedwe.

Kuyesa ndi Kusamalira:

NFPA 20 imatchula ndondomeko zoyesera ndi machitidwe osamalira kuti awonetsetse kuti mapampu amoto akugwira ntchito bwino pakufunika.

Miyezo ya Kachitidwe:

Muyezowu umaphatikizapo njira zogwirira ntchito zomwe mapampu ozimitsa moto ayenera kukwaniritsa kuti awonetsetse kuti pali madzi okwanira komanso kuthamanga kwa ntchito zozimitsa moto.

Magetsi:

Imakhudza kufunika kokhala ndi magetsi odalirika, kuphatikizapo machitidwe osungira, kuonetsetsa kuti mapampu amoto amatha kugwira ntchito panthawi yadzidzidzi.

Kuchokera ku nfpa.org, imati NFPA 20 imateteza moyo ndi katundu popereka zofunikira pakusankha ndi kukhazikitsa mapampu kuti zitsimikizire kuti machitidwe azigwira ntchito monga momwe akufunira kupereka madzi okwanira komanso odalirika pakagwa ngozi yamoto.

Mmene MungawerengerePompo ya Madzi a MotoKupanikizika?

Kuti muwerengere kuthamanga kwa pampu yamoto, mutha kugwiritsa ntchito njira iyi:

Fomula:

Kumene:

· P = Kuthamanga kwapampu mu psi (mapaundi pa inchi imodzi)

Q = Kuthamanga kwa magaloni pamphindi (GPM)

· H = Mutu wonse wamphamvu (TDH) m'mapazi

F = Kutayika kwachangu mu psi

Njira Zowerengera Kuthamanga kwa Pampu ya Moto:

Tsimikizirani Mayendedwe (Q):

- Dziwani kuchuluka kwamayendedwe ofunikira pachitetezo chamoto, chomwe nthawi zambiri chimafotokozedwa mu GPM.

Werengerani Total Dynamic Head (TDH):

· Mutu Wokhazikika: Yezerani mtunda woyima kuchokera ku gwero la madzi mpaka pamalo okwera kwambiri okhetsedwa.

Kutayika kwa Mkangano: Kuwerengera kutayika kwa mikangano mu makina a mapaipi pogwiritsa ntchito ma chart otayika kapena ma fomula (monga equation ya Hazen-Williams).

· Kutayika Kwamakwenje: Kuwerengera zakusintha kulikonse kwa kukwera pamakina.

[TDH= Static Head + Friction Loss + Elevation Loss]

Yerekezerani Kutayika kwa Mkangano (F):

Gwiritsani ntchito ma fomula kapena ma chart oyenerera kuti muwone kutayika kwa mikangano potengera kukula kwa chitoliro, kutalika, ndi kuchuluka kwa mayendedwe.

Lumikizani Makhalidwe mu Fomula:

Sinthani mayendedwe a Q, H, ndi F mu fomula yowerengera mphamvu ya mpope.

Kuwerengera Chitsanzo:

· Mtengo Woyenda (Q): 500 GPM

· Total Dynamic Head (H): 100 mapazi

Kutaya Kwachangu (F): 10 psi

Pogwiritsa ntchito formula:

Mfundo Zofunika:

· Onetsetsani kuti kukakamizidwa kowerengeka kukukwaniritsa zofunikira zachitetezo chamoto.

· Nthawi zonse tchulani milingo ya NFPA ndi ma code apafupi ndi zofunikira ndi malangizo.

Funsani ndi injiniya woteteza moto kuti mupeze makina ovuta kapena ngati simukutsimikiza kuwerengera kulikonse.

Kodi Mumawona Bwanji Kuthamanga Kwa Pampu Yamoto?

Kuti muwone kuthamanga kwa pampu yamoto, mutha kutsatira izi:

1. Sonkhanitsani Zida Zofunikira:

Pressure Gauge: Onetsetsani kuti muli ndi sikelo yoyezera kuthamanga yomwe imatha kuyeza kuchuluka kwa kuthamanga komwe kukuyembekezeka.

Wrenches: Kulumikiza geji ku mpope kapena mapaipi.

Zida Zachitetezo: Valani zida zoyenera zotetezera, kuphatikiza magolovesi ndi magalasi.

2. Pezani Pressure Test Port:

Dziwani doko loyesa kukakamiza papampu yamoto. Izi nthawi zambiri zimakhala pambali yotulutsa mpope.

3. Lumikizani Pressure Gauge:

Gwiritsani ntchito zoyikira zoyenera kuti mulumikize choyezera cha kuthamanga kwa doko loyeserera. Onetsetsani kuti ali ndi chisindikizo cholimba kuti asatayike.

4. Yambitsani Pampu ya Moto:

Yatsani mpope wamoto molingana ndi malangizo a wopanga. Onetsetsani kuti makinawo ndi oyambira komanso okonzeka kugwira ntchito.

5. Yang'anani Kuwerenga Kwaposachedwa:

Pompo ikamathamanga, yang'anani kuchuluka kwa kuthamanga kwa gauge. Izi zidzakupatsani mphamvu yotulutsa pampu.

6. Lembani Kupanikizika:

Zindikirani kukakamizidwa kuwerengedwa kwa zolemba zanu. Fananizani ndi kukakamizidwa kofunikira komwe kumatchulidwa pamapangidwe adongosolo kapena miyezo ya NFPA.

7. Onani Zosiyanasiyana:

Ngati n'koyenera, yang'anani kupanikizika pamagulu osiyanasiyana othamanga (ngati dongosolo limaloleza) kuonetsetsa kuti pampu ikugwira ntchito bwino pamtunda wake wonse.

8. Tsekani Pompo:

Mutatha kuyezetsa, tsegulani mpope mosamala ndikuchotsa choyezera champhamvu.

9. Yang'anirani Nkhani:

Pambuyo poyesa, yang'anani dongosolo kuti muwone ngati pali kutayikira kapena zolakwika zomwe zingafunike chisamaliro.

Mfundo Zofunika:

Chitetezo Choyamba: Nthawi zonse tsatirani ndondomeko zachitetezo mukamagwira ntchito ndi mapampu amoto ndi makina oponderezedwa.

Kuyesa Kwanthawi Zonse: Kuwunika pafupipafupi kwamphamvu ndikofunikira kuti pampu yamoto ikhale yodalirika.

Kodi Kupanikizika Kocheperako Kotsalira Kwa Pampu Yamoto Ndi Chiyani?

Kupanikizika kochepa kotsalira kwa mapampu ozimitsa moto nthawi zambiri kumadalira zofunikira zachitetezo chamoto ndi ma code amderalo. Komabe, muyezo wamba ndikuti kupanikizika kocheperako kotsalira kuyenera kukhala kosachepera 20 psi (mapaundi pa mainchesi) pamalo otulutsira payipi akutali kwambiri panthawi yomwe ikuyenda kwambiri.

Izi zimatsimikizira kuti pali kukakamizidwa kokwanira kuti apereke bwino madzi kumalo opondereza moto, monga sprinkler kapena hoses.
