Kusamalira Silinda ya SCBA: Liti Komanso Momwe Mungasinthire Masilinda Okulungidwa A Ulusi Wokulungidwa

Zida Zodzipangira Zopuma (SCBA) ndizofunikira kwa ozimitsa moto, ogwira ntchito yopulumutsa, ndi ena omwe amagwira ntchito m'malo owopsa.SCBA silindas amapereka mpweya wovuta wopuma m'madera omwe mpweya ukhoza kukhala wapoizoni kapena wopanda mpweya. Kuonetsetsa kuti zida zimagwira ntchito bwino komanso moyenera, ndikofunikira kuzisamalira ndikuzisinthaSCBA silindas pafupipafupi. M’nkhaniyi tikambirana kwambiricomposite fiber-wokutidwa ndi silindas, makamaka kaboni fiber, yomwe imakhala ndi moyo wazaka 15. Tiwunikanso zofunikira pakukonza, kuphatikiza kuyesa kwa hydrostatic ndi kuyang'ana kowoneka.

Kodi Ndi ChiyaniComposite Fiber-Yokutidwa ndi SCBA Cylinders?

Silinda ya SCBA yokhala ndi ulusi wambiris amapangidwa ndi liner yamkati yopepuka yopangidwa kuchokera ku zinthu monga aluminiyamu kapena pulasitiki, yomwe imakutidwa ndi zinthu zamphamvu zophatikizika monga kaboni fiber, fiberglass, kapena Kevlar. Masilindalawa ndi opepuka kwambiri kuposa masilinda akale achitsulo kapena aluminiyamu okha, kuwapangitsa kukhala abwino kugwiritsidwa ntchito pakagwa mwadzidzidzi komwe kumayenda ndikofunikira.Silinda ya SCBA yokhala ndi kaboni fibers, makamaka, amagwiritsidwa ntchito kwambiri chifukwa amapereka kuphatikiza kwabwino kwamphamvu, kulemera, ndi kulimba.

Kutalika kwa moyo waCarbon Fiber-Yokutidwa ndi SCBA Cylinders

Silinda ya SCBA yokhala ndi kaboni fibers ali ndi moyo wamba wa15 zaka. Pambuyo pa nthawiyi, ziyenera kusinthidwa, mosasamala kanthu za chikhalidwe chawo kapena maonekedwe. Chifukwa cha moyo wokhazikika uwu ndi chifukwa cha kung'ambika kwapang'onopang'ono pazitsulo zophatikizika, zomwe zimatha kufooketsa pakapita nthawi, ngakhale palibe kuwonongeka kowonekera. Kwa zaka zambiri, silinda imakumana ndi zovuta zosiyanasiyana, kuphatikiza kusinthasintha kwamphamvu, zinthu zachilengedwe, komanso zomwe zingachitike. Pamenecomposite fiber-wokutidwa ndi silindas adapangidwa kuti azitha kuthana ndi izi, kukhulupirika kwazinthuzo kumachepa pakapita nthawi, zomwe zitha kubweretsa ngozi.

Zoyendera Zowoneka

Chimodzi mwazinthu zofunika kwambiri komanso zokonzekera pafupipafupiSCBA silindas ndikuyang'ana kowoneka. Kuyang'ana kumeneku kumayenera kuchitidwa musanagwiritse ntchito komanso mukatha kugwiritsa ntchito nthawi iliyonse kuti adziwe zizindikiro zilizonse zowonongeka, monga ming'alu, ming'alu, mikwingwirima, kapena dzimbiri.

Zinthu zazikuluzikulu zomwe muyenera kuziyang'ana pakuwunika kowona ndi izi:

• Kuwonongeka kwapamtunda: Yang'anani ming'alu kapena tchipisi chilichonse chomwe chili mu chokulunga chakunja cha silinda.
• Dents: Dents kapena mapindikidwe mu mawonekedwe a silinda angasonyeze kuwonongeka kwa mkati.
• Zimbiri: Pamenecomposite fiber-wokutidwa ndi silindas imagonjetsedwa ndi dzimbiri kuposa zitsulo, zitsulo zilizonse zowonekera (monga valavu) ziyenera kufufuzidwa ngati zizindikiro zadzimbiri kapena zowonongeka.
• Delamination: Izi zimachitika pamene zigawo zakunja zimayamba kupatukana ndi mzere wamkati, zomwe zitha kusokoneza mphamvu ya silinda.

Ngati zina mwa izi zapezeka, silinda iyenera kuchotsedwa ntchito nthawi yomweyo kuti iwunikenso.

Zofunikira Zoyezetsa Hydrostatic

Kuwonjezera pa kuyang'anitsitsa nthawi zonse,SCBA silindas ayenera kukumanakuyesa kwa hydrostaticpazigawo zoikika. Kuyesa kwa hydrostatic kumatsimikizira kuti silinda imatha kukhalabe ndi mpweya wothamanga kwambiri popanda kuyika pachiwopsezo chophulika kapena kutayikira. Kuyesa kumaphatikizapo kudzaza silinda ndi madzi ndikuukakamiza kupitirira mphamvu yake yogwiritsira ntchito kuti muwone ngati pali zizindikiro zowonjezera kapena kulephera.

Kuchuluka kwa kuyezetsa kwa hydrostatic kumadalira mtundu wa silinda:

• Masilinda opangidwa ndi fiberglassayenera kuyesedwa hydrostatic iliyonsezaka zitatu.
• Silinda yokhala ndi kaboni fiberskuyenera kuyesedwa kulikonsezaka zisanu.

Pakuyesa, ngati silinda ikukula kupitilira malire ovomerezeka kapena ikuwonetsa kupsinjika kapena kutayikira, idzalephera mayeso ndipo iyenera kuchotsedwa ntchito.

Chifukwa Chiyani Zaka 15?

Mungadabwe chifukwa chakekaboni fiber-wokutidwa SCBA yamphamvus ali ndi nthawi yeniyeni ya zaka 15, ngakhale ndikukonza ndi kuyesa nthawi zonse. Yankho lagona mu mtundu wa zinthu zopangidwa. Ngakhale kuti ndi zamphamvu kwambiri, kaboni fiber ndi zosakaniza zina zimakhalanso zotopa komanso zowonongeka pakapita nthawi.

Zinthu zachilengedwe monga kusintha kwa kutentha, kukhudzana ndi kuwala kwa dzuwa (ma radiation a UV), ndi mphamvu zamakina zimatha kufooketsa zomangira zamaguluwo. Ngakhale kusinthaku sikungawonekere nthawi yomweyo kapena kuzindikirika pakuyezetsa kwa hydrostatic, zotsatira zochulukirapo pazaka za 15 zimawonjezera chiopsezo cholephera, ndichifukwa chake mabungwe olamulira, monga department of Transportation (DOT), amalowetsa m'malo pa 15- chaka chizindikiro.

Zotsatira za Kunyalanyaza Kusintha ndi Kusamalira

Kulephera kusintha kapena kukonzaSCBA silindas zitha kubweretsa zotsatira zoyipa, kuphatikiza:

1. Kulephera kwa Cylinder: Ngati silinda yowonongeka kapena yofooka ikugwiritsidwa ntchito, pali ngozi yoti imasweka ndi kupanikizika. Izi zitha kuvulaza kwambiri ogwiritsa ntchito ndi ena omwe ali pafupi.
2. Kuchepa kwa mpweya: Silinda yowonongeka ikhoza kulephera kusunga kuchuluka kwa mpweya wofunikira, kuchepetsa mpweya wopuma wa wogwiritsa ntchito panthawi yopulumutsa kapena kuzimitsa moto. M'mikhalidwe yowopsa, mphindi iliyonse ya mpweya imawerengedwa.
3. Zilango zowongolera: M'mafakitale ambiri, kutsatira malamulo achitetezo ndikofunikira. Kugwiritsa ntchito masilinda akale kapena osayesedwa kungayambitse chindapusa kapena zilango zina kuchokera kwa oyang'anira chitetezo.

Zabwino Zochita zaSCBA CylinderKusamalira ndi Kusintha

Kuwonetsetsa kuti masilinda a SCBA azikhala otetezeka komanso ogwira mtima pa moyo wawo wonse, ndikofunikira kutsatira izi:

1. Kuyang'ana kowoneka bwino: Yang'anani masilindala ngati ali ndi vuto lililonse musanagwiritse ntchito komanso mukatha.
2. Kuyesedwa kwa hydrostatic yokhazikika: Dziwani nthawi yomwe silinda iliyonse idayesedwa komaliza ndikuwonetsetsa kuti yayesedwanso mkati mwa nthawi yofunikira (zaka zisanu zilizonsecarbon fiber-wokutidwa ndi silindas).
3. Kusungirako koyenera: SitoloSCBA silindas pamalo ozizira, owuma, kutali ndi kuwala kwa dzuwa kapena kutentha kwambiri, komwe kungapangitse kuwonongeka kwa zinthu.
4. Sinthani pa nthawi yake: Osagwiritsa ntchito masilinda kupitilira zaka 15 za moyo wawo. Ngakhale akuwoneka kuti ali bwino, chiopsezo cholephera chimawonjezeka kwambiri pambuyo pa nthawiyi.
5. Sungani zolemba zatsatanetsatane: Sungani zipika za masiku oyendera, zotsatira za mayeso a hydrostatic, ndi ndandanda zosinthira silinda kuti muwonetsetse kuti zikutsatira malamulo ndi ndondomeko zachitetezo.

Mapeto

SCBA silindas, makamaka zokulungidwa ndi kaboni fiber, ndi chida chofunikira kwa iwo omwe amagwira ntchito m'malo owopsa. Masilinda awa amapereka njira yopepuka koma yolimba yonyamula mpweya woponderezedwa. Komabe, amabwera ndi zofunikira zosamalira bwino komanso zosinthidwa kuti zitsimikizire chitetezo. Kuwunika pafupipafupi, kuyezetsa ma hydrostatic zaka zisanu zilizonse, ndikusintha m'malo mwake pakatha zaka 15 ndi njira zazikulu zomwe zimathandiza kusungaSCBA silindandi odalirika komanso otetezeka kugwiritsa ntchito. Potsatira malangizowa, ogwiritsa ntchito amatha kuwonetsetsa kuti ali ndi mpweya womwe amafunikira pakafunika kwambiri, osasokoneza chitetezo.
