Ayini amathangi e-SCBA agcwele?

Ithangi lokuphefumula elinakuzenzela (i-SCBA) ithangiIzindlela zokuphepha ezibalulekile ezisetshenziselwa izimboni ezahlukahlukene, kufaka phakathi ukucisha umlilo, imisebenzi yokutakula, nokuphathwa okungokwezinto okuyingozi. Lawa mathangi ahlinzeka ngokuhlinzekwa komoya ophefumulayo kubasebenzisi abadinga ukusebenza ezindaweni lapho umoya ungcoliswe khona noma amazinga we-oksijini aphansi. Ukuqonda iniIthangi le-SCBAIzinto ezigcwele futhi izinto ezisetshenziselwa ukuzikha zibalulekile ekwaziseni ukusebenza kwazo kanye nokuqinisekisa ukusetshenziswa kwazo ngempumelelo ezimeni eziphuthumayo.

IniIthangi le-SCBAaqukethe

Ithangi le-SCBAS, eyaziwa nangokuthi ama-Cylinders, aklanyelwe ukugcina nokunikeza umoya ocindezelwe noma umoya-mpilo kumuntu ogqokile. Nakhu ukubheka okuningiliziwe kokuqukethwe nokwakhiwa kwalawa mathangi:

1. Umoya ocindezelwe

KakhuluIthangi le-SCBAkugcwele umoya ocindezelwe. Umoya ocindezelwe ngumoya ocindezelwe ezingeni eliphakeme kunokucindezela komkhathi. Lokhu kucubungula kuvumela inani elikhulu lomoya ukuthi ligcinwe ithangi elincane, okwenza kube lusizo ukuthi lusetshenziswe ezimweni ezahlukahlukene. Umoya ocindezelwe ngaphakathiIthangi le-SCBAI-S ejwayelekile iqukethe:

• I-oksijini:Cishe i-21% yomoya i-oksijini, okuyiphesenti elifanayo elitholakala emoyeni osezingeni lolwandle.
• I-nitrogen namanye amagesi:Ama-79% asele enziwe nge-nitrogen kanye namanani amanani athile atholakala emkhathini.

Umoya ocindezelwe ngaphakathiIthangi le-SCBAKuhlanzwa ukususa ukungcola, ukuqinisekiswa ukuthi kuphephile ukuphefumula ngisho nasezindaweni ezingcolile.

2. Ucindezelwe umoya-mpilo

Kwamanye amayunithi akhethekile we-SCBA, amathangi agcwele umoya-mpilo omsulwa ocindezelwe esikhundleni somoya. Lawa mayunithi asetshenziswa ezimweni ezithile lapho kudingeka khona i-oksijini ephakeme noma lapho ikhwalithi yomoya isengozini enkulu. I-oxygen ecindezelwe ngokuvamile isetshenziswa ku:

• Izimo eziphuthumayo:Lapho kungadingeka khona-ke umoya-mpilo ezigulini ezinezinkinga zokuphefumula.
• Imisebenzi Ephakeme Ephakeme:Lapho amazinga we-oxygen ephansi, futhi ukugcwala okuphezulu kwe-oksijini kuyazuzisa.

Ukwakhiwa kweIthangi le-SCBAs

Ithangi le-SCBAIklanyelwe ukubekezelela izingcindezi eziphakeme nezimo ezinzima. Ukukhethwa kwezinto ezisetshenziselwa ukwakhiwa kwalawa amathangi kubalulekile ngokusebenza kwazo nokuphepha.I-Carbon fiber Composite Cylinders bangukhetho oludumile ngenxa yezakhiwo zabo eziphakeme. Nakhu ukubhekisisa okusondele kulezi zinto:

1. I-Carbon fiber Composite Cylinders

I-Carbon fiber Composite CylinderIsetshenziswa kabanzi ezinhlelweni ezinhlelweni ze-SCBA ngenxa yamandla azo kanye nezakhiwo ezingasindi. Izici eziphambili zalawa masilinda zihlanganisa:

• I-liner yangaphakathi:I-liner engaphakathi yesilinda, ngokuvamile enziwa ngezinto ezifana ne-aluminium noma ipulasitiki, ibambe umoya ocindezelwe noma umoya-mpilo.
• Ukugoqwa kwe-carbon fiber:Ungqimba lwangaphandle lwesilinda senziwa kusuka ezintweni ze-carbon fiber composite. I-carbon fiber iyinto eqinile, engasindi enikeza isilinganiso esiphakeme sokuqina kwesisindo kanye nokumelana nomthelela nokugqwala.

Izinzuzo zeI-Carbon fiber Composite Cylinders:

• Engasindi: Isilinda se-carbon fibers zilula kakhulu uma ziqhathaniswa nensimbi yendabuko noma ama-aluminium cylinders. Lokhu kubenza babe lula ukuthwala nokuphatha, okubaluleke kakhulu ezimweni eziphezulu kakhulu njengezicishamlilo noma imisebenzi yokutakula.
• Amandla aphezulu:Naphezu kokungasindi,I-Carbon fiber Composite CylinderS unamandla amakhulu futhi angamelana nezingcindezi eziphakeme. Lokhu kuqinisekisa ukuthi isilinda singabambelela ngokuphepha umoya ocindezelwe noma umoya-mpilo ngaphandle kwengozi yokuqhuma.
• Ukuqina:I-Carbon fiber imelana nokugqwala kanye nomonakalo ezivela ezintweni zezemvelo. Lokhu kwenezela ekufeni okukodwa kwamasilinda, okwenza bathembeke ezimweni ezinzima.
• Ukusebenza kahle:Umklamo weisilinda se-carbon fiberIvumela ukuba bagcine umoya omningi noma umoya-mpilo endaweni encane, enikeza abasebenzisi nge-applatus ehlangene futhi esebenza kahle.

2. Ezinye izinto zokwakha

• I-Aluminium Liner:-NyeIthangi le-SCBASebenzisa i-aluminium liner, elula kunensimbi futhi inikeze ukumelana okuhle nokugqwala. Lawa mathangi avame ukugoqwa ngezinto ezihlanganisiwe, njenge-fiberglass noma i-carbon fiber, ukuthuthukisa amandla awo.
• Amathangi ensimbi:Amathangi e-SCBA wendabuko enziwe ngensimbi, eqinile kodwa enamandla kune-aluminium noma izinto ezihlanganisiwe. Amathangi ensimbi asasetshenziswa kwezinye izinhlelo zokusebenza kepha kancane kancane afakwa esikhundleni ngezindlela ezikhanyayo.

Ukulungiswa nokuphepha

UkuqinisekisaIthangi le-SCBAKugcwaliswa kahle futhi kugcinwa kahle kubalulekile ukuphepha nokusebenza:

• Ukuhlolwa okujwayelekile: Ithangi le-SCBAkufanele ihlolwe njalo ukuthola izimpawu zokugqoka noma ukulimala. Lokhu kufaka ukubheka ama-dents, imifantu, noma ezinye izindaba ezingabeka engcupheni ubuqotho bethangi.
• Ukuhlolwa kweHydrostatic: Ithangi le-SCBAKumele ahlole ukuhlolwa kwe-hydrostatic ngezikhathi ezithile ukuze aqinisekise ukuthi angamelana nezingcindezi eziphakeme zenzelwe zona. Lokhu kubandakanya ukugcwalisa ithangi ngamanzi futhi ucindezele ukubheka ukuvuza noma ubuthakathaka.
• Ukugcwaliswa okufanele:Amathangi kufanele agcwaliswe ngochwepheshe abaqeqeshiwe ukuqinisekisa ukuthi umoya noma umoya-mpilo ucindezelwe ingcindezi efanele nokuthi ithangi liphephile ukulisebenzisa.

Ukugcina

Ithangi le-SCBAS udlala indima ebalulekile ekunikezeni umoya ophefumulayo noma umoya-mpilo ezindaweni eziyingozi. Ukukhethwa kwezinto ezibonakalayo kwalawa amathangi kunomthelela omkhulu ekusebenzeni kwawo.Amasilinda e-carbon fiber compositeUbe yinketho edumile ngenxa yokungasindi, amandla aphezulu, nokuqina. Banikela ngezinzuzo ezibalulekile ngaphezulu kwensimbi yendabuko noma amathangi we-aluminium, kufaka phakathi ukuphathwa okulula nokuphepha okuthuthukile. Ukulungiswa njalo nokuphathwa okufanele kwalawa mathangi kuqinisekisa ukuthembeka kwabo nokusebenza ngempumelelo, kubenza babaluleke ekuphepheni ezimweni eziphuthumayo kanye nezinsizakalo zezimboni.
