Kodi ozimitsa moto amagwiritsa ntchito mtundu wanji wa SCBA?

Ozimitsa moto amadalira Self-Contained Breathing Apparatus (SCBA) kuti adziteteze ku mpweya woipa, utsi, ndi malo opanda mpweya wa okosijeni panthawi ya ntchito zozimitsa moto. SCBA ndi chida chofunikira kwambiri pazida zodzitetezera, zomwe zimalola ozimitsa moto kuti azipuma bwino pomwe akulimbana ndi zoopsa. Ma SCBA amakono omwe amagwiritsidwa ntchito ndi ozimitsa moto ndi apamwamba kwambiri, akuphatikiza zigawo zosiyanasiyana kuti zitsimikizire chitetezo, chitonthozo, ndi kulimba. Chimodzi mwazinthu zofunika kwambiri pamakina amakono a SCBA ndikugwiritsa ntchitocarbon fiber composite silindas, zomwe zimapereka zabwino kwambiri potengera kulemera, kulimba, komanso kugwiritsa ntchito mosavuta.

Nkhaniyi ikufotokoza za mitundu ya ozimitsa moto a SCBAs amagwiritsa ntchito, makamaka pa ntchito yacarbon fiber composite silindas ndi chifukwa chake akukhala chisankho chokhazikika pazida zozimitsa moto.

Zida za SCBA ndi Mitundu

Dongosolo la SCBA logwiritsidwa ntchito ndi ozimitsa moto lili ndi zigawo zingapo zofunika:

1. Air Cylinder:Thempweya yamphamvundi gawo la SCBA lomwe limasunga mpweya wopumira pansi pa kupanikizika kwakukulu, kulola ozimitsa moto kupuma m'malo owopsa.
2. Pressure Regulator ndi Hoses:Zigawozi zimachepetsa mpweya wothamanga kwambiri womwe umasungidwa mu silinda mpaka mpweya wopuma, womwe umaperekedwa kwa wozimitsa moto kupyolera mu mask.
3. Chigoba cha nkhope (Chigoba cha nkhope):Chophimba kumaso ndi chophimba chosindikizidwa chomwe chimateteza nkhope ya ozimitsa moto pamene akupereka mpweya. Zapangidwa kuti zipereke chisindikizo cholimba kuti utsi ndi mpweya wowopsa usalowe mu chigoba.
4. Harness ndi Backplate:Dongosolo la harness limateteza SCBA ku thupi la ozimitsa moto, kugawa kulemera kwa silinda ndikulola wogwiritsa ntchito kuyenda momasuka.
5. Ma Alamu ndi Monitoring Systems:Ma SCBA amakono nthawi zambiri amaphatikizapo ma alarm ophatikizika omwe amachenjeza ozimitsa moto ngati mpweya wawo uli wochepa kapena ngati dongosolo likukumana ndi vuto lililonse.

Mitundu ya Air Cylinders mu Firefighting SCBA

Silinda ya mpweya ndiye gawo lofunika kwambiri la SCBA, chifukwa limapereka mpweya wopumira. Masilinda amagawidwa makamaka ndi zida zomwe amapangidwa, ndi chitsulo, aluminiyamu, ndicarbon fiber composite silindas kukhala ambiri. Mu ntchito zozimitsa moto,carbon fiber composite silindanthawi zambiri amakondedwa chifukwa cha zabwino zambiri.

Masilinda achitsulo

Masilinda achitsulo ndi chisankho chachikhalidwe cha ma SCBA ndipo amadziwika chifukwa cha kulimba kwawo komanso kuthekera kwawo kupirira zovuta zambiri. Komabe, masilindala achitsulo ndi olemetsa, zomwe zimapangitsa kuti asakhale oyenera kuzimitsa moto. Kulemera kwa silinda yachitsulo kungapangitse kuti ozimitsa moto azitha kuyenda mofulumira komanso moyenera, makamaka m'malo opanikizika kwambiri monga nyumba zoyaka moto.

Aluminium Cylinders

Masilinda a aluminiyamu ndi opepuka kuposa chitsulo koma amalemerabe kuposa ma silinda a carbon fiber composite. Amapereka malire abwino pakati pa mtengo ndi kulemera koma sangapereke mlingo wofanana wa chitonthozo kapena kumasuka kwa kuyenda monga ma cylinders a carbon fiber mu ntchito zowonjezereka zozimitsa moto.

Carbon Fiber Composite Cylinders

Silinda ya carbon fiber composites atuluka ngati chisankho chokondedwa cha machitidwe amakono a SCBA omwe amagwiritsidwa ntchito ndi ozimitsa moto. Masilindalawa amapangidwa ndi kukulunga chingwe chamkati (chomwe chimapangidwa kuchokera ku aluminiyamu kapena pulasitiki) chokhala ndi zigawo za carbon fiber, zomwe ndi zopepuka komanso zamphamvu kwambiri. Chotsatira chake ndi silinda yomwe imatha kusunga mpweya pazovuta kwambiri pomwe imakhala yopepuka kwambiri kuposa njira zina zachitsulo kapena aluminiyamu.

Ubwino waCarbon Fiber Composite Cylinders:

1. Opepuka: Silinda ya carbon fiber composites ndi opepuka kwambiri kuposa ma silinda achitsulo ndi aluminiyamu. Kuchepetsa kulemera kumeneku kungapangitse kusiyana kwakukulu pa ntchito zazitali zozimitsa moto, kumene kukwanitsa kuyenda mofulumira komanso moyenera n'kofunika kwambiri.
2. Kukhalitsa:Ngakhale kuti ndi wopepuka,carbon fiber composite silindas ndi amphamvu kwambiri komanso olimba. Amatha kupirira kupsinjika kwakukulu ndipo amalimbana ndi zowonongeka kuchokera ku zowonongeka, zomwe zimawapangitsa kukhala oyenerera pazovuta zomwe ozimitsa moto nthawi zambiri amakumana nazo.
3. Kulimbana ndi Corrosion:Mosiyana ndi chitsulo,mpweya wa carbon fiber cylinders sachita dzimbiri, zomwe zimawonjezera moyo wawo wautali komanso zimachepetsa kufunika kokonza pafupipafupi.
4. Moyo Wautali Wautumiki:Kutengera mtundu wa silinda,carbon fiber composite silindaali ndi moyo wautumiki mpaka zaka 15 (Mtundu 3), pomwe ena atsopanoLembani masilinda 4 okhala ndi PET liners mwina alibe malire a moyo wautumiki pansi pamikhalidwe ina. Izi zimawapangitsa kukhala ndalama zotsika mtengo kwa nthawi yayitali.
5. Mpweya Wokwera:Chifukwa cha kuthekera kwawo kunyamula mpweya pazovuta kwambiri,carbon fiber composite silindas amalola ozimitsa moto kunyamula mpweya wambiri mu phukusi lopepuka. Izi zikutanthauza kuti amatha kukhala m'malo owopsa kwa nthawi yayitali osafunikira kusintha masilinda.

BwanjiCarbon Fiber Cylinders Pindulani Ozimitsa Moto

Ozimitsa moto amayenera kuyenda mofulumira ndikugwira ntchito pamalo ovuta kwambiri, ndipo zipangizo zomwe amanyamula zisawachedwetse.Silinda ya carbon fiber composites ndi njira yothetsera vutoli, yopereka ubwino waukulu womwe umapititsa patsogolo mphamvu za ozimitsa moto pa ntchito.

Kuthamanga Kwambiri

Kulemera kopepuka kwampweya wa carbon fiber cylinders zikutanthauza kuti ozimitsa moto amakhala ochepa kwambiri ndi zida zawo. Masilinda achitsulo achikhalidwe amatha kulemera mapaundi a 25, zomwe zimawonjezera mavuto kwa ozimitsa moto omwe amavala kale zovala zoteteza komanso zonyamula zida zowonjezera.Carbon fiber cylinders, mosiyana, akhoza kulemera zosakwana theka la kuchuluka kwake. Kuchepetsa kulemera kumeneku kumathandiza ozimitsa moto kuti azikhala ndi mphamvu komanso liwiro, zomwe zimakhala zofunikira poyenda m'nyumba zodzaza utsi kapena kukwera masitepe panthawi yadzidzidzi.

Kuwonjezeka kwa Air Supply for Long Oparesheni

Phindu lina lacarbon fiber composite silindas ndi kuthekera kwawo kusunga mpweya pazitseko zapamwamba-kawirikawiri 4,500 psi (mapaundi pa inchi imodzi) kapena kuposa, poyerekeza ndi kutsika kwapansi muzitsulo zazitsulo kapena aluminiyamu. Mphamvu yapamwambayi imalola ozimitsa moto kunyamula mpweya wopumira popanda kuwonjezera kukula kapena kulemera kwa silinda, kuwapangitsa kukhalabe ndi ntchito kwa nthawi yayitali osafunikira kubwereranso kuti asinthe silinda.

Kukhalitsa M'malo Ovuta

Kuzimitsa moto kumakhala kovutirapo ndipo kumachitika m'malo owopsa pomwe zida zimakhala ndi kutentha kwambiri, zinyalala zakuthwa, komanso kusagwira bwino ntchito.Silinda ya carbon fiber compositeadapangidwa kuti athe kulimbana ndi zovuta izi. Kukulunga kwa kaboni fiber kumapereka chitetezo chowonjezera ku zovuta ndi mphamvu zina zakunja, kuchepetsa mwayi wowonongeka ndikuwongolera kudalirika kwathunthu kwa dongosolo la SCBA.

Kusamalira ndi Moyo Wautumiki

Carbon fiber cylinders, makamakaType 3 silindas okhala ndi zomangira za aluminiyamu, nthawi zambiri amakhala ndi moyo wazaka 15. Panthawiyi, amayenera kuyang'anitsitsa ndikuyesedwa nthawi zonse kuti atsimikizire kuti ali otetezeka komanso akugwira ntchito.Lembani masilinda 4, omwe amagwiritsa ntchito pulasitiki (PET)., ikhoza kukhala ndi moyo wopanda malire malinga ndi kugwiritsidwa ntchito ndi chisamaliro. Moyo wautali wautumiki uwu ndi mwayi wina womwe umapangitsampweya wa carbon fiber cylindersa kusankha kothandiza m'madipatimenti ozimitsa moto.

Mapeto

Ozimitsa moto amakumana ndi zoopsa zomwe zingawononge moyo wawo akamagwira ntchito, ndipo amadalira zida zawo kuti zitetezeke. Makina a SCBA ndi gawo lofunikira la zida zawo zotetezera, ndipo silinda ya mpweya imagwira ntchito yofunika kwambiri pakuwonetsetsa kuti mpweya wopumira umakhala wokhazikika m'malo oopsa.Silinda ya carbon fiber composites akhala chisankho chapamwamba pamakina a SCBA pakuzimitsa moto chifukwa chopepuka, cholimba, komanso kapangidwe kake kapamwamba. Masilindalawa amapereka zabwino zambiri kuposa zitsulo zachikhalidwe ndi aluminiyamu, kupititsa patsogolo kuyenda, chitonthozo, ndi magwiridwe antchito a ozimitsa moto. Pamene ukadaulo wa SCBA ukupitilirabe kusinthika,mpweya wa carbon fiber cylinders idzakhalabe gawo lofunikira pakuwongolera chitetezo cha ozimitsa moto ndi ntchito.
