Agcwaliswa Ngani Amathangi e-SCBA?

Ithangi le-Self-Contained Breathing Apparatus (SCBA).amathuluzi okuphepha abalulekile asetshenziswa ezimbonini ezihlukahlukene, okuhlanganisa izicishamlilo, imisebenzi yokuhlenga, nokuphatha izinto eziyingozi. Lawa mathangi ahlinzeka ngomoya ophefumulayo kubasebenzisi abadinga ukusebenza ezindaweni lapho umoya ungcolile khona noma amazinga komoyampilo ephansi ngokuyingozi. Ukuqonda ukuthi yiniI-SCBA tanks zigcwaliswa futhi izinto ezisetshenziselwa ukuzakha zibalulekile ekwaziseni ukusebenza kwazo kanye nokuqinisekisa ukuthi zisetshenziswa ngempumelelo ezimeni eziphuthumayo.

IniI-SCBA Tanks Iqukethe

I-SCBA tanks, owaziwa nangokuthi amasilinda, aklanyelwe ukugcina futhi anikeze umoya ocindezelwe noma umoya-mpilo kumuntu owugqokile. Nakhu ukubuka okuningiliziwe kokuqukethwe nokwakhiwa kwalawa mathangi:

1. Umoya Ocindezelwe

IningiI-SCBA tanks agcwele umoya ocindezelweyo. Umoya ocindezelwe umoya ocindezelwe wafinyelela ezingeni eliphezulu kunomfutho womkhathi. Lokhu kucindezela kuvumela inani elibalulekile lomoya ukuthi ligcinwe ethangini elincane uma kuqhathaniswa, okwenza lisebenziseke ezimeni ezihlukahlukene. Umoya ocindezelwe ungeneI-SCBA tanks ngokuvamile iqukethe:

• Umoya-mpilo:Cishe u-21% womoya umoya-mpilo, okuyiphesenti elifanayo elitholakala emkhathini olwandle.
• I-nitrogen namanye amagesi:Ama-79% asele akhiwe nge-nitrogen futhi alandele amanani amanye amagesi atholakala emkhathini.

Umoya ocindezelwe ungeneI-SCBA tanks iyahlanzwa ukuze ikhiphe ukungcola, iqinisekise ukuthi iphephile ukuphefumula ngisho nasezindaweni ezingcolile.

2. I-Oxygen ecindezelwe

Kwamanye amayunithi akhethekile e-SCBA, amathangi agcwala umoya-mpilo ocindezelwe omsulwa esikhundleni somoya. Lawa mayunithi asetshenziswa ezimeni ezithile lapho kudingeka khona ukugcwala okuphezulu komoyampilo noma lapho izinga lomoya lonakele kakhulu. I-oxygen ecindezelwe ngokuvamile isetshenziswa ku:

• Izimo Eziphuthumayo Zezempilo:Lapho kungase kudingeke khona umoya-mpilo ohlanzekile ezigulini ezinezinkinga zokuphefumula.
• Ukusebenza kwe-High Altitude:Lapho amazinga e-oxygen ephansi, futhi ukugcwala okuphezulu komoya-mpilo kuyazuzisa.

Ukwakhiwa kweI-SCBA Tanks

I-SCBA tanks zenzelwe ukumelana nezingcindezi eziphezulu kanye nezimo ezinzima. Ukukhethwa kwezinto ezisetshenziswa ekwakhiweni kwala mathangi kubalulekile ekusebenzeni nokuphepha kwawo.Isilinda esiyinhlanganisela ye-carbon fibres kukhona ukukhetha okudumile ngenxa yezindawo zabo eziphakeme. Nakhu ukuhlolisisa lezi zinsiza:

1. I-Carbon Fiber Composite Cylinders

Isilinda esiyinhlanganisela ye-carbon fibres asetshenziswa kakhulu ezinhlelweni ze-SCBA ngenxa yamandla awo nezakhiwo ezingasindi. Izingxenye eziyinhloko zalawa masilinda zihlanganisa:

• I-Inner Liner:Ilayini yangaphakathi yesilinda, ngokuvamile eyenziwe ngezinto ezifana ne-aluminium noma ipulasitiki, ibamba umoya ocindezelwe noma umoya-mpilo.
• Ukugoqa kweCarbon Fiber:Ungqimba lwangaphandle lwesilinda lwenziwe nge-carbon fiber composite material. I-Carbon fiber iyinto eqinile, engasindi enikeza isilinganiso esiphezulu samandla nesisindo kanye nokumelana nomthelela nokugqwala.

Izinzuzo zeI-Carbon Fiber Composite Cylinders:

• Okungasindi: I-carbon fibre cylinders alula kakhulu uma kuqhathaniswa nensimbi evamile noma amasilinda e-aluminium. Lokhu kuwenza kube lula ukuwaphatha nokubamba, okubaluleke kakhulu ezimeni ezishubile njengokucisha umlilo noma imisebenzi yokuhlenga.
• Amandla Aphezulu:Naphezu kokuba nesisindo esincane,isilinda esiyinhlanganisela ye-carbon fibres ziqine ngendlela emangalisayo futhi zingamelana nezingcindezi eziphezulu. Lokhu kuqinisekisa ukuthi isilinda singabamba ngokuphephile umoya ocindezelwe noma umoya-mpilo ngaphandle kwengozi yokuqhekeka.
• Ukuqina:I-carbon fiber imelana nokugqwala kanye nokulimala okuvela ezintweni zemvelo. Lokhu kunezela ekuphileni isikhathi eside kwamasilinda, okwenza athembeke ngisho nasezimweni ezinzima.
• Ukusebenza kahle:Umklamo wei-carbon fibre cylinders izivumela ukuthi zigcine umoya omningi noma umoya-mpilo endaweni encane, zinikeze abasebenzisi izisetshenziswa zokuphefumula ezihlangene nezisebenza kahle.

2. Ezinye Izinto

• I-Aluminium Liner:AbanyeI-SCBA tanks sebenzisa i-aluminium liner, elula kunensimbi futhi enikeza ukumelana okuhle nokugqwala. Lawa mathangi avame ukusongwa ngento eyinhlanganisela, njenge-fiberglass noma i-carbon fiber, ukuze athuthukise amandla awo.
• Amathangi Ensimbi:Amathangi e-SCBA endabuko enziwe ngensimbi, eqinile kodwa esindayo kune-aluminium noma izinto eziyinhlanganisela. Amathangi ensimbi asasetshenziswa kwezinye izinhlelo zokusebenza kodwa kancane kancane athathelwa indawo amanye alula.

Ukugcinwa Nokuphepha

Ukuqinisekisa iI-SCBA tanks zigcwaliswe ngendlela efanele futhi zigcinwe kahle zibalulekile ekuphepheni nasekusebenzeni:

• Ukuhlola Okuvamile: I-SCBA tankkufanele ihlolwe njalo ukuze kubhekwe izimpawu zokuguga noma zokulimala. Lokhu kuhlanganisa ukuhlola ukucwila, ukuqhekeka, noma ezinye izinkinga ezingase zibe engozini ubuqotho bethangi.
• Ukuhlolwa kwe-Hydrostatic: I-SCBA tanks kumele zihlolwe ngezikhathi ezithile ukuze kuqinisekiswe ukuthi zingakwazi ukumelana nezingcindezi ezidizayinelwe. Lokhu kuhlanganisa ukugcwalisa ithangi ngamanzi nokulicindezela ukuze uhlole ukuvuza noma ubuthakathaka.
• Ukugcwalisa Okufanelekile:Amathangi kufanele agcwaliswe ngochwepheshe abaqeqeshiwe ukuze kuqinisekiswe ukuthi umoya noma umoya-mpilo ucindezelwa ukucindezela okulungile nokuthi ithangi liphephile ukusetshenziswa.

Isiphetho

I-SCBA tanks idlala indima ebalulekile ekuhlinzekeni umoya ophefumulayo noma umoya-mpilo ezindaweni eziyingozi. Ukukhethwa kwezinto zala mathangi kuba nomthelela omkhulu ekusebenzeni kwawo.Amasilinda ayinhlanganisela ye-carbon fibresebeyinketho edumile ngenxa yesisindo sabo esingasindi, amandla aphezulu, nokuqina. Banikeza izinzuzo ezibalulekile ngaphezu kwamathangi ensimbi noma e-aluminium evamile, okuhlanganisa ukuphatha okulula nokuphepha okuthuthukisiwe. Ukugcinwa okuvamile nokuphathwa ngendlela efanele kwala mathangi kuqinisekisa ukwethembeka nokusebenza kwawo, okuwenza abaluleke kakhulu ekuphepheni kwezicelo ezihlukahlukene eziphuthumayo nezimboni.
