Zeziphi iiTanki zeSCBA eziGcwaliswa Ngayo?

Itanki ye-Self-Contained Breathing Apparatus (SCBA).s zizixhobo zokhuseleko ezibalulekileyo ezisetyenziswa kumashishini ahlukeneyo, kubandakanywa ukulwa nomlilo, imisebenzi yokuhlangula, kunye nokuphatha izinto ezinobungozi. La matanki anikezela ngokunikezela komoya ophefumlayo kubasebenzisi abafuna ukusebenza kwindawo apho umoya ungcolisekile okanye amanqanaba e-oxygen aphantsi ngokuyingozi. Ukuqonda ntoniItanki ye-SCBAs zizaliswe kunye nezinto ezisetyenziselwa ukuzakha zibalulekile ekuxabiseni ukusebenza kwazo kunye nokuqinisekisa ukusetyenziswa kwazo ngokufanelekileyo kwiimeko zikaxakeka.

IntoniITanki yeSCBAs Ziqulathe

Itanki ye-SCBAs, ekwaziwa ngokuba yi-cylinders, yenzelwe ukugcina kunye nokubonelela ngomoya oxinanisiweyo okanye ioksijini kumntu oyinxibileyo. Nalu ujongo oluneenkcukacha kwimixholo kunye nolwakhiwo lwala matanki:

1. Umoya ocinezelekileyo

UninziItanki ye-SCBAs zizaliswe ngumoya ocinezelweyo. Umoya ocinezelweyo ngumoya ocinezelekileyo ukuya kwinqanaba eliphezulu kunoxinzelelo lwe-atmospheric. Olu xinzelelo luvumela umthamo omkhulu womoya ukuba ugcinwe kwitanki encinci, okwenza kube yinto esebenzayo kwiimeko ezahlukeneyo. Umoya oxiniweyo ungeneItanki ye-SCBAs ngokuqhelekileyo ziquka:

• Ioksijini:Malunga ne-21% yomoya yioksijini, eyipesenti enye efumaneka kwiatmosfera kwinqanaba lolwandle.
• Nitrogen kunye nezinye iigesi:I-79% eseleyo yenziwe yinitrogen kwaye ilandele izixa zezinye iigesi ezifumaneka emoyeni.

Umoya ocinezelweyo ungeneItanki ye-SCBAs iyacocwa ukuze isuse ukungcola, iqinisekisa ukuba ikhuselekile ekuphefumleni nakwindawo ezingcolisekileyo.

2. Ioksijeni exineneyo

Kwezinye iiyunithi ezikhethekileyo ze-SCBA, iitanki zizaliswe yioksijini ecinezelweyo ecocekileyo endaweni yomoya. Ezi yunithi zisetyenziselwa kwiimeko ezithile apho i-oksijeni ephezulu ifunekayo okanye apho umgangatho womoya uphazamiseka kakhulu. Ioksijini ecinezelweyo isetyenziswa ngokubanzi ku:

• UNgxamiseko lwezonyango:Apho ioksijini ecocekileyo inokufunwa kwizigulana ezinemiba yokuphefumla.
• Imisebenzi yoMphakamo oPhezulu:Apho amanqanaba e-oksijini ephantsi, kunye nokuxinwa okuphezulu kwe-oxygen kunenzuzo.

Ukwakhiwa kweITanki yeSCBAs

Itanki ye-SCBAs zenzelwe ukumelana noxinzelelo oluphezulu kunye neemeko ezinzima. Ukukhethwa kwezinto ezisetyenziselwa ukwakhiwa kwala matanki kubalulekile ekusebenzeni kwabo kunye nokhuseleko.Ikhabhon fibre composite cylinders lukhetho oludumileyo ngenxa yeepropati zabo eziphezulu. Nalu ujongo olusondeleyo kwezi mathiriyeli:

1. I-Carbon Fiber Composite Cylinders

Ikhabhon fibre composite cylinders zisetyenziswa ngokubanzi kwiinkqubo ze-SCBA ngenxa yamandla azo kunye neempawu ezikhaphukhaphu. Amacandelo aphambili ale cylinder abandakanya:

• Ilayini yangaphakathi:I-liner yangaphakathi ye-cylinder, eyenziwe kwizinto ezifana ne-aluminiyam okanye iplastiki, ibamba umoya ocinezelweyo okanye i-oxygen.
• Ukusonga kweCarbon Fiber:Umaleko wangaphandle we-cylinder wenziwa kwi-carbon fiber composite material. Ifayibha yeCarbon yinto eyomeleleyo, ekhaphukhaphu enika umlinganiselo wokomelela ukuya kubunzima kunye nokumelana neempembelelo kunye nokudleka.

Izinto ezilungileyo zeI-Carbon Fiber Composite Cylinders:

• Khaphukhaphu: Ikhabhoni fiber cylinders zikhaphukhaphu kakhulu xa kuthelekiswa nentsimbi yemveli okanye iisilinda aluminiyam. Oku kwenza kube lula ukuthwala kunye nokusingatha, okubaluleke ngakumbi kwiimeko eziphezulu ezifana nokucima umlilo okanye imisebenzi yokuhlangula.
• Amandla aphezulu:Nangona ilula,carbon fiber composite cylinderzomelele ngendlela emangalisayo kwaye ziyakwazi ukumelana noxinzelelo oluphezulu. Oku kuqinisekisa ukuba i-cylinder inokubamba ngokukhuselekileyo umoya ocinezelweyo okanye i-oxygen ngaphandle kwengozi yokuphuka.
• Ukuqina:Ifayibha yeCarbon iyamelana nokubola kunye nomonakalo ovela kwizinto ezisingqongileyo. Oku kongeza ixesha elide leesilinda, okwenza ukuba zithembeke nakwiimeko ezinzima.
• Ukusebenza kakuhle:Uyilo lwecarbon fiber cylinders ibavumela ukuba bagcine umoya omninzi okanye ioksijini kwindawo encinci, ibonelela abasebenzisi ngesixhobo sokuphefumla esixineneyo nesisebenzayo.

2. Ezinye Izinto

• Umgca weAluminiyam:AbanyeItanki ye-SCBAs sebenzisa i-aluminium liner, ekhaphukhaphu kunentsimbi kwaye inika ukuxhathisa okulungileyo kwi-corrosion. La matanki ahlala esongelwe ngezinto ezidibeneyo, njengefiberglass okanye i-carbon fiber, ukukhulisa amandla abo.
• Iitanki zentsimbi:Iitanki ze-SCBA zemveli zenziwe ngentsimbi, eyomeleleyo kodwa inzima kune-aluminiyam okanye izinto ezidibeneyo. Iitanki zentsimbi zisasetyenziswa kwezinye iinkqubo kodwa ngokuthe ngcembe zitshintshwa ngezinye iindlela ezikhaphukhaphu.

ULondolozo noKhuseleko

Ukuqinisekisa iItanki ye-SCBAzizaliswe ngokuchanekileyo kwaye zigcinwe ngokufanelekileyo zibalulekile kukhuseleko kunye nokusebenza:

• Uhlolo lwarhoqo: Itanki ye-SCBAkufuneka zihlolwe rhoqo iimpawu zokuguga okanye umonakalo. Oku kuquka ukujonga izibonda, iintanda, okanye eminye imiba enokubeka esichengeni isidima setanki.
• Uvavanyo lweHydrostatic: Itanki ye-SCBAs kufuneka zenze uvavanyo lwe-hydrostatic ngamaxesha athile ukuqinisekisa ukuba banokumelana noxinzelelo oluphezulu abayilelwe. Oku kubandakanya ukugcwalisa itanki ngamanzi kwaye uyicinezele ukujonga ukuvuza okanye ubuthathaka.
• Ukuzaliswa ngokufanelekileyo:Amatanki kufuneka azaliswe ngabaqeqeshi abaqeqeshiweyo ukuqinisekisa ukuba umoya okanye i-oksijini ixinzelelwe kuxinzelelo oluchanekileyo kwaye itanki ikhuselekile ukuyisebenzisa.

Ukuqukumbela

Itanki ye-SCBAidlala indima ebalulekileyo ekunikeni umoya ophefumlayo okanye ioksijini kwiindawo ezinobungozi. Ukukhethwa kwezinto zala matanki kuchaphazela kakhulu ukusebenza kwazo.Iisilinda zekharbon fibre compositeziye zaba lukhetho oludumileyo ngenxa yobunzima bazo, amandla aphezulu, kunye nokuqina. Banikezela ngeenzuzo ezibalulekileyo ngaphezu kweetanki zentsimbi okanye i-aluminium yendabuko, kubandakanywa ukuphatha lula kunye nokhuseleko oluphuculweyo. Ukugcinwa rhoqo kunye nokuphathwa ngokufanelekileyo kwala matanki kuqinisekisa ukuthembeka kwawo kunye nokusebenza kwawo, okwenza kube yinto ebalulekileyo ekukhuseleni kwizicelo ezahlukeneyo ezingxamisekileyo kunye nezoshishino.
