SCBA Cylinder Maintenance: Rini uye Sei Kutsiva Composite Fiber-Akaputirwa Masilinda

Self-Contained Breathing Apparatus (SCBA) yakakosha kune vanodzima moto, vashandi vekununura, uye vamwe vanoshanda munzvimbo dzine njodzi.SCBA humburumbiras inopa yakakosha kupihwa kwemweya unofema munzvimbo umo mhepo inogona kunge ine muchetura kana kushomeka kweokisijeni. Kuve nechokwadi chekuti michina inoshanda zvakachengeteka uye zvinobudirira, zvakakosha kuchengetedza uye kutsivaSCBA humburumbiras nguva dzose. Munyaya ino, tichanyanya kufungacomposite fiber-yakaputirwa silindas, kunyanya kabhoni fiber, ine hupenyu hwesevhisi hwemakore gumi nemashanu. Isu tichaongorora zvakare zvinodiwa zvekuchengetedza, kusanganisira hydrostatic kuyedzwa uye yekuona yekuongorora.

ChiiComposite Fiber-Yakaputirwa SCBA Cylinders?

Composite fiber-yakaputirwa SCBA silindas anonyanya kuvakwa neakareruka remukati liner yakagadzirwa kubva kune zvinhu zvakaita sealuminium kana plastiki, iyo yakaputirwa mune yakasimba composite zvinhu senge kabhoni fiber, fiberglass, kana Kevlar. Aya masilinda akareruka kupfuura echinyakare simbi kana aruminiyamu-chete masilinda, zvichiita kuti ave akakodzera kushandiswa mumamiriro echimbichimbi apo kufamba kwakakosha.Carbon fiber-yakaputirwa SCBA silindas, kunyanya, anoshandiswa zvakanyanya nekuti anopa mubatanidzwa wakanakisa wesimba, uremu, uye kusimba.

Hupenyu hweCarbon Fiber-Yakaputirwa SCBA Cylinders

Carbon fiber-yakaputirwa SCBA silindas vane hupenyu hurefu hwe15 makore. Mushure menguva iyi, dzinofanira kuchinjwa, pasinei nemamiriro avo ezvinhu kana chitarisiko. Chikonzero cheiyi hupenyu hwakagadziriswa nekuda kwekupfeka zvishoma nezvishoma uye kubvarura pazvinhu zvakaumbwa, izvo zvinogona kupera simba nekufamba kwenguva, kunyangwe pasina kukuvara kunoonekwa kuripo. Nekufamba kwemakore, silinda inoratidzwa kune dzakasiyana siyana zvinonetsa, kusanganisira kuchinjika kwekumanikidza, mamiriro ekunze, uye zvinogona kukanganisa. Nepocomposite fiber-yakaputirwa silindas dzakagadzirirwa kubata aya mamiriro, kutendeseka kwezvinhu kunoderera nekufamba kwenguva, izvo zvinogona kuunza njodzi yekuchengetedza.

Visual Inspections

Imwe yeanonyanya kukosha uye anogara achigadzirisa maitiro eSCBA humburumbiras ndizvokuongorora kwekuona. Ongororo idzi dzinofanirwa kuitwa pamberi uye mushure mekushandisa kwega kwega kuona chero zviratidzo zvinooneka zvekukuvadzwa, senge makatsemuka, mazino, mabrasions, kana ngura.

Zvinhu zvakakosha zvekutarisa panguva yekuongorora zvinosanganisira:

• Kukuvadzwa kwechiso: Tarisa uone kana pakatsemuka kana machipisi ari muhumburumbira wekunze wakaputirwa.
• Dents: Dents kana deformation muhumburumbira chimiro chinogona kuratidza kukuvara kwemukati.
• Corrosion: Panguvacomposite fiber-yakaputirwa silindas inoshingirira mukuora kupfuura simbi, chero nhengo dzesimbi dziri pachena (sevharuvhu) dzinofanira kuongororwa zviratidzo zve ngura kana kusakara.
• Delamination: Izvi zvinoitika kana mativi ekunze anoumbwa anotanga kupatsanurwa kubva kune yemukati liner, zvinogona kukanganisa simba rehumburumbira.

Kana imwe yeiyi nyaya yawanikwa, silinda inofanira kubviswa kubva kubasa nekukurumidza kuti iongororwe zvakare.

Hydrostatic Testing Zvinodiwa

Pamusoro pekuongorora nguva dzose kwekuona,SCBA humburumbiras inofanira kuitikakuongorora hydrostaticpanguva yakatarwa. Kuyedzwa kweHydrostatic kunovimbisa kuti silinda inogona kuramba iine mweya wekudzvanya wakachengeteka pasina njodzi kuputika kana kuvuza. Muedzo unosanganisira kuzadza silinda nemvura uye nekuidzvanya kupfuura yakajairika kushanda kwayo kuti utarise chero zviratidzo zvekuwedzera kana kutadza.

Kuwanda kweye hydrostatic kuyedzwa kunoenderana nerudzi rwe silinda:

• Fiberglass-yakaputirwa masilindainoda kuongororwa hydrostatic yesemakore matatu.
• Carbon fiber-yakaputirwa silindaszvinoda kuongororwa zvesemakore mashanu.

Munguva yekuyedzwa, kana silinda ikawedzera kupfuura miganhu inogamuchirwa kana kuratidza zviratidzo zvekushushikana kana kudonha, inotadza bvunzo uye inofanira kubviswa pabasa.

Sei Makore 15?

Ungashamisika kuti seikabhoni faibha-yakaputirwa SCBA humburumbiras vane hurefu hwehupenyu hwemakore gumi nemashanu, kunyangwe nekugadzirisa nguva dzose uye kuyedzwa. Mhinduro iri muchimiro chezvakaumbwa zvinhu. Kunyange yakasimba zvakanyanya, kabhoni fiber uye mamwe macomposites zvakare ari pasi pekuneta uye kuderedzwa nekufamba kwenguva.

Zvinhu zvakatipoteredza zvakaita sekuchinja kwetembiricha, kuvhenekerwa nechiedza chezuva (UV radiation), uye mashandiro emuchina anogona kunetesa zvishoma nezvishoma zvisungo muzvikamu zvakaumbwa. Kunyangwe shanduko idzi dzingasakurumidza kuoneka kana kuonekwa panguva yekuyedzwa kwehydrostatic, iwo akawedzera mhedzisiro pamusoro pemakore gumi nemashanu anowedzera njodzi yekutadza, ndosaka masangano anodzora, akadai seDhipatimendi rekutakura (DOT), anoraira kutsiva pa15- year mark.

Migumisiro Yekuregeredza Kutsiva uye Kuchengeta

Kutadza kutsiva kana kuchengetedzaSCBA humburumbiras inogona kutungamirira kumigumisiro yakaipa, kusanganisira:

1. Cylinder kukundikana: Kana silinda yakakuvadzwa kana isina simba ikashandiswa, pane njodzi yekuti inoputika pasi pekumanikidzwa. Izvi zvinogona kukonzera kukuvara kwakanyanya kumushandisi nevamwe vari pedyo.
2. Kuderedzwa kwemhepo: Silinda yakakuvadzwa inogona kusakwanisa kuchengetedza huwandu hunodiwa hwemhepo, ichidzikamisa mhepo inofema yemushandisi panguva yekununura kana kudzima moto. Mumamiriro ezvinhu anotyisidzira upenyu, miniti yega yega yemhepo inokosha.
3. Regulatory zvirango: Mumaindasitiri mazhinji, kutevedzera mitemo yekuchengetedza kunosungirwa. Kushandisa masilinda echinyakare kana asina kuongororwa kunogona kutungamira kumaricho kana zvimwe zvirango kubva kune vanochengetedza kuchengetedza.

Best Practices forSCBA CylinderMaintenance uye Replacement

Kuve nechokwadi chekuti masilinda eSCBA anoramba akachengeteka uye achishanda kwehupenyu hwavo hwose, zvakakosha kutevedzera aya akanakisa maitiro:

1. Kuongororwa kwekuona nguva dzose: Tarisa masilinda kune chero zviratidzo zvekukuvara pamberi uye mushure mekushandisa kwega kwega.
2. Yakarongwa hydrostatic yekuongorora: Chengetedza kuti silinda imwe neimwe yakapedzisira kuongororwa riini uye uone kuti inoongororwazve mukati menguva inodiwa (makore mashanu ega egakabhoni fiber-yakaputirwa silindas).
3. Kuchengetedza kwakakodzera: ChitoroSCBA humburumbiras munzvimbo inotonhorera, yakaoma, kure nezuva rakananga kana tembiricha yakanyanyisa, izvo zvinogona kukurumidza kuparara kwezvinhu.
4. Tsiva nenguva: Usashandise masilinda kupfuura makore e15 ehupenyu hwavo. Kunyange kana vachiita sevari mumamiriro ezvinhu akanaka, njodzi yekukundikana inowedzera zvakanyanya mushure menguva ino.
5. Chengetedza zvinyorwa zvakadzama: Chengetedza matanda emazuva ekuongorora, hydrostatic bvunzo mhinduro, uye silinda yekutsiva masheti kuti uve nechokwadi chekuteedzera mirau uye kuchengetedza mapuroteni.

Mhedziso

SCBA humburumbiras, kunyanya kabhoni fiber-yakaputirwa, chinhu chakakosha chemidziyo kune avo vanoshanda munzvimbo dzine njodzi. Aya masilinda anopa mhinduro isingaremi asi yakasimba yekutakura mweya wakamanikidzwa. Nekudaro, ivo vanouya neakasimba kuchengetedza uye kutsiva zvinodiwa kuti ave nechokwadi chekuchengeteka. Kugara uchiongorora kwekuona, hydrostatic kuyedzwa makore mashanu ega ega, uye kutsiva nenguva mushure memakore gumi nemashanu maitiro akakosha anobatsira kuchengetedza.SCBA humburumbiras yakavimbika uye yakachengeteka kushandisa. Nekutevedzera iyi nhungamiro, vashandisi vanogona kuve nechokwadi chekuti vane mhepo yavanoda kana ichinyanya kukosha, pasina kukanganisa kuchengetedza.
