Zithini iitanki ze-SCBA?

Isixhobo sokuphefumla esinee-aptus (SCBA) itankiS zisisixhobo sezinto zokhuseleko ezibalulekileyo ezisetyenziswa kumashishini ahlukeneyo, kubandakanya ukugcinwa kwamashishini, imisebenzi yokuhlangula, kunye nokuphatha izinto ezinobungozi. Ezi tanki zibonelela ngomoya ophefumlayo kubasebenzisi abafuna ukusebenza kwiindawo apho umoya ungcoliseka khona okanye ioksijini yingozi. Ukuqonda ukuba yintoniItanki ye-SCBAS zigcwele kwaye izixhobo ezisetyenziselwa ukwakha ngabo zibalulekile ukuze zikwazi ukuxabisa ukusebenza kwazo nokuqinisekisa ukusetyenziswa kwabo ngempumelelo kwiimeko zikaxakeka.

IntoniItanki ye-SCBAiqulethe

Itanki ye-SCBAS, ekwabizwa ngokuba zii-cylinders, zenzelwe ukugcina kwaye zibonelela ngomoya oxinzelelweyo okanye ioksijini ukuya kulowo ulithandayo. Nazi iinkcukacha zijonga imixholo kunye nolwakhiwo lwezitanki:

1. Umoya oxinzelelweyo

UninziItanki ye-SCBAzizaliswe ngumoya oxinzelelweyo. Umoya oxinzelelweyo ngumoya ocinezelwe kwinqanaba eliphezulu kunexinzelelo lomoya. Olu xinzelelo luvumela inani elikhulu lomoya ukuba ligcinwe kwitanki elincinci, liyenza ilungele ukusetyenziswa kwiimeko ezahlukeneyo. Umoya oxinzelelweyo ngaphakathiItanki ye-SCBANgokwesiqhelo iquka:

• Ioksijini:Malunga neepesenti ezingama-21 zomoya yioksijini, eyipesenti enye efumaneka kwimozulu kwinqanaba lolwandle.
• I-nitrogen kunye nezinye iigesi:I-79% eseleyo yenziwa nge-nitrogen kunye nexabiso lezinye iigesi ezifumaneka emoyeni.

Umoya oxinzelelweyo ngaphakathiItanki ye-SCBAS ukuhlanjululwa ukuba ususe ukungafezeki, ukuqinisekisa ukuba kukhuselekile ukuphefumla nakwimimandla engcolisekileyo.

2. Inyanzelise ioksijini

Kwezinye iiyunithi ze-SCK ezikhethekileyo, iitanki zizaliswe yioksijini egudileyo yesiqhelo endaweni yomoya. Ezi yunithi zisetyenziswa kwiimeko ezithile apho uxinzelelo oluphezulu lweoksijini luyafuneka okanye apho umgangatho womoya ulalanise kakhulu. I-OXYGENTION yeoksijini isetyenziswa ngokubanzi:

• Imeko yongxamiseko kwezonyango:Apho ioksijini ecocekileyo inokufuneka khona kwizigulana ezinemicimbi yokuphefumla.
• Umsebenzi ophezulu:Apho amanqanaba eoksijini asezantsi, kwaye uxinzelelo oluphezulu lweoksijini luyingenelo.

Ukwakhiwa kweItanki ye-SCBAs

Itanki ye-SCBAzenzelwe ukumelana noxinzelelo oluphezulu kunye neemeko ezinzima. Ukukhetha izixhobo ezisetyenziselwa ukwakhiwa kwezi tanki kubalulekile ukuze zisebenze kunye nokhuseleko lwabo.I-carbon fiber ye-carbon sylinderS Ngaba lukhetho oludumileyo ngenxa yepropathi yabo ephezulu. Nantsi indlela ukujonga ezi zinto:

1. I-carbon fiber ye-carbon sylinders

I-carbon fiber ye-carbon sylinderIsetyenziswe ngokubanzi kwiinkqubo ze-SCBA ngenxa yamandla abo kunye neepropathi zawo. Izinto eziphambili zezi zilinda zibandakanya:

• I-Liner engaphakathi:I-Liner yangaphakathi yesilinda, eyenziwe ngezinto ezinjenge-aluminium okanye iplastiki, ibambe umoya oxinzelelweyo okanye ioksijini.
• I-carbon fiber isonge:Umaleko wangaphandle we-cylinder wenziwa kwi-carbon fiber fiber. I-carbon fiber yindawo eyomeleleyo, elula eqinileyo ebonelela ngamandla kunye nokungaxhathisi kwimpembelelo kunye nokunyanzelwa.

Izibonelelo zeI-carbon fiber ye-carbon sylinders:

• Isibane: I-carbon fiber cylinderI-Sight kakhulu xa kuthelekiswa nentsimbi yemveli okanye i-aluminium yesilinda. Oku kubangela ukuba bathwale kwaye basingatha, okubaluleke ngokukodwa kwiimeko ezinobunzima obukhulu njengokusebenza komlilo okanye zokuhlangula.
• Amandla aphezulu:Ngaphandle kokuba lukhaphukhaphu,I-carbon fiber ye-carbon sylinderswomelele kakhulu kwaye unokumelana noxinzelelo oluphezulu. Oku kuqinisekisa ukuba isilinda sinokubamba ngokukhuselekileyo umoya oxinzelelweyo okanye ioksijini ngaphandle komngcipheko wokuqhekeka.
• Ukuqina:I-carbon fiber iyamelana nokungasebenzi kakuhle kunye nomonakalo kwizinto zokusingqongileyo. Oku kongeza kubomi obude beesilinda, kubenza bathembeke kwiimeko ezinzima.
• Ukusebenza:Uyilo lweI-carbon fiber cylinderIbavumela ukuba bagcine umoya ongaphezulu okanye ioksijini kwindawo encinci, enikezela abasebenzisi nge-compacting kunye nesixhobo esifanelekileyo sokuphefumla.

2. Ezinye izinto

• I-Aluminium Liner:EzinyeItanki ye-SCBASebenzisa i-liminum liner, elula kunentsimbi kwaye inika ukumelana nokunganyangeki ekusuleni. Ezi tanki zihlala zisongelwe ngezinto ezihlanganisiweyo, njenge-fiberglass okanye i-carbon fiber, yokuphucula amandla abo.
• Iitanki zensimbi:Iitanki zemveli zemveli zenziwa kwintsimbi, eyomeleleyo kodwa inzima kune-aluminium okanye ezihlanganisiweyo. Iitanki zensimbi zisasetyenziswa kwezinye iinkqubo kodwa ngokuthe ngcembe zithathelwa indawo ziindlela eziphakamileyo.

Ukulungiswa nokhuseleko

Ukuqinisekisa iItanki ye-SCBAIzaliswa ngokuchanekileyo kwaye igcinwe ngokufanelekileyo ibalulekile ekukhuseleni nasekusebenzeni:

• Uvavanyo rhoqo: Itanki ye-SCBAs kufuneka ihlolwe rhoqo kwimiqondiso yokunxiba okanye yomonakalo. Oku kubandakanya ukukhangela iidenti, rocks, okanye eminye imiba enokuthi ithobele ingqibelelo yetanki.
• Uvavanyo lwe-hydrostatic: Itanki ye-SCBAS kufuneka enze uvavanyo lwe-hydrostatic uphyrostatic ukuqinisekisa ukuba banokumelana noxinzelelo oluphezulu abayilelwe. Oku kubandakanya ukuzalisa itanki ngamanzi kwaye icinezele ukukhangela ukuvuza okanye ubuthathaka.
• Ukugcwaliswa ngokuchanekileyo:Iitanki kufuneka zigcwaliswe ziingcali eziqeqeshiweyo ukuqinisekisa ukuba umoya okanye ioksijini inyanzelwa kwingcinezelo echanekileyo kwaye itanki ikhuselekile ukuyisebenzisa.

Ukuqukumbela

Itanki ye-SCBAIndima ebalulekileyo ekunikezeleni ngomoya okuphefumla okanye ioksijini kwiindawo eziyingozi.
