Ukuqonda umahluko phakathi kweetanki ze-SCBA kunye ne-SCBA: isishwankathelo esineenkcukacha

Xa kufikwa kwiitanki zoxinzelelo oluphezulu, ezimbini zeyona ntlobo zixhaphakileyo yi-SCBA Zombini zinceda iinjongo ezibi ngokubonelela ngomoya okhule, kodwa uyilo, ukusetyenziswa, kunye neenkcazo zahluke kakhulu. Nokuba ukhathazekile kwimisebenzi yokuhlangula engxamisekileyo, ukucima umlilo, okanye ukuntywila kwamanzi, ukuqonda umahluko phakathi kwale tanki kubalulekile. Eli nqaku liza kuqhuba kumehluko ophambili, egxile kwindima yeI-carbon fiber ye-carbon sylinders, enoguquko zombini iitanki ze-SCA kunye ne-scuba.

I-SCBA VS. SCBA: Iinkcazo ezisisiseko

1. I-SCBAIinkqubo ze-SCBA zilungiselelwe indawo apho umoya uphefumlayo ulathwe. Oku kunokubandakanya abacimi-mlilo abangenise izakhiwo ezigcwalisiweyo zomsi, abasebenzi bezithuthi kwiindawo ezinetyhefu, okanye abaphenduli ngokungxamisekileyo abaphatha iindleko ezinobungozi. Iitanki ze-SCBA zenzelwe ukubonelela ngomoya ococekileyo kangangexesha elifutshane, ngokuqhelekileyo kwiimeko zomhlaba ezingaphezulu apho kungabikho kufikelela kutshabalala.
2. I-scuba (ikwisixhobo sokuphefumla esingaphantsi kwamanzi): Iinkqubo zeScuba, kwelinye icala, zenzelwe ngokukodwa ukusetyenziswa kwephantsi kwamanzi, zisebenze ngeendawo zokuphefumla ngelixa ziphantsi. Itanki ye-Scuba

Ngelixa zombini iintlobo zeetanki zibonelela ngomoya, zisebenza kwiindawo ezahlukeneyo kwaye zakhiwe ngenkcazo eyahlukeneyo yokufezekisa iimfuno zokusetyenziswa kwazo.

Izixhobo kunye nolwakhiwo: Indima yeI-carbon fiber ye-carbon sylinders

Enye yezona nkqubela phambili zibalulekileyo kuzo zombini itekhnoloji ye-SCBA kunye netekhnoloji ye-SCUBA kukusetyenziswaI-carbon fiber ye-carbon sylinders. Iitanki zendabuko zenziwe ngentsimbi okanye i-aluminium, ethi, nangona iqinisekile, inzima kwaye inzima kwaye inzima. I-carbon fiber, kunye nomyinge wayo ophezulu-ukuya kwinqanaba lezinto eziphakamileyo, iye yaba kukhetho lwezinto ezibonakalayo kwiitanki zanamhlanje.

1. Inzuzo yobunzima: I-carbon fiber ye-carbon sylinderI-s ilula kakhulu kunetanki okanye i-aluminium. Kwiinkqubo ze-SBA, ukunciphisa ubunzima kubaluleke kakhulu. Abacimi-mlilo kunye nabasebenzi abahlangulayo kufuneka bathathe igiya enzima, ngoko ke ubunzima bezinto zabo zokuphefumla zivumela ukushukuma okukhulu kwaye kunciphisa ukudinwa. Iitanki ze-SCBA ezenziwe kwi-farbon fiber ikwi-50% ilula kune-overpart nganye yentsimbi, ngaphandle kokulalanisa kumandla okanye ukuqina.Kwiitanki zeScuba, ubume bokukhanya kwe-carbon fiber ikwabonelela ngezibonelelo. Ngelixa iphantsi kwamanzi, ubunzima abufanelanga yinkxalabo, kodwa i-handers ithwele iitanki ukuya kuthi ga emanzini okanye zilayishe kwiinqanawa, ubunzima obuncitshisiweyo zenza ukuba amava alawuleke ngakumbi.
2. Ukuqina kunye noxinzelelo: I-carbon fiber ye-carbon sylinderAbantu bayaziwa ngamandla abo aphelele, kwabenza babe nokumelana noxinzelelo lwangaphakathi. Iitanki ze-SCBA zihlala zifuna ukugcina umoya oxinzelelweyo kwiingcinezelo ze-4,500 ze-psi, kwaye i-carbon fiber ibonelela ngengqibelelo eyimfuneko yokuthatha uxinzelelo oluphezulu. Oku kubalulekile kukuhlangula okanye ukucima umlilo, apho iitanki ziphantsi kweemeko ezigqithisileyo kwaye nakuphi na ukusilela kwinkqubo kunokubangela ubomi bobomi.Iitanki zeScuba, ezihlala zigcina umoya kwiindawo ezinoxinzelelo oluphakathi kwe-3 000 ne-3 500 psi, ziyaxhamla kwi-Carbon Fiber. Ukwahluka kuya kufuneka kufuna isiqinisekiso sokuba iitanki zabo zinokuphatha uxinzelelo oluphezulu lwe-air oqulunqwe ngaphandle komngcipheko wokuqhekeka. I-Calbon ye-Carbon ye-Carbon Fiber iqinisekisa ukhuseleko ngelixa inciphisa i-bulk yetanki.
3. Ixesha elide: Iintsiba zangaphandle zeItanki ye-carbon fibers ihlala ibandakanyaIngubo ePhakamileyo yePolymerkunye nezinye izixhobo zokukhusela. Ezi zale zikhusela ukunxiba ngokusingqongileyo, njengokufuma, ukuvezwa kwemichiza, okanye ukonakala komzimba. Kwiitanki ze-SCA, ezinokusetyenziswa kwiimeko ezinzima ezinje ngemililo okanye iingozi zophuhliso, olu nkuselo wongezwe ubalulekile ekwenzeni ubomi betanki.Iitanki zeScuba, zivezwe kwiindawo zetyuwa, zixhamle kwinkcaso yokunganyangeki ukuba i-carbon fiber kunye neengubo ezikhuselayo zibonelela. Iitanki zensimbi zemveli zinokuyalela ngokuhamba kwexesha ngenxa yokuvezwa kwamanzi kunye netyuwa, kantiItanki ye-carbon fickSixhathisa olu hlobo lokuphefumla.

Umsebenzi kwaye usebenzise kwiindawo ezahlukeneyo

Indawo apho iitanki zeSba kunye ne-SCBAMA zisetyenziswa ngokuthe ngqo kuyilo lwabo kunye nokusebenza kwayo.

1. Ukusetyenziswa kwe-SCBA: Iitanki ze-SCBA zihlala zisetyenziswangaphezulu komhlabaOkanye uvalelwe indawo apho kukho umngcipheko okufutshane kubomi bomntu kumsi, igesi, okanye i-oxygen ye-oxygen. Kwezi meko, eyona njongo iphambili kukubonelela ngokufikelela kwithuba elifutshane lomoya ngelixa umsebenzisi wenza imisebenzi yokuhlangula okanye uphume kwindawo eyingozi. Iitanki ze-SCBA zihlala zixhotyiswe ngeealarms ezizisa uMhlambi xa umoya ubaleka uphantsi, ugxininisa indima yabo njengesisombululo sexesha elifutshane.
2. Ukusetyenziswa kwe-scuba: Iitanki zeScuba zenzelweIxesha elide lokuphumlasebenzisa. Imixwaba ixhomekeke kwezi tanki ukuphefumla okanye isebenza emanzini anzongonzongo. Iitanki zeScuba zilungelelaniswe ngononophelo ukubonelela ngemixokelelwane efanelekileyo yegesi (umoya okanye umxube wegesi) ukuqinisekisa ukuphefumla okukhuselekileyo phantsi kobuqhetseba kunye noxinzelelo. Ngokungafaniyo neetanki ze-SCBA, iitanki zeScuba zenzelwe ukuhlala ixesha elide, zihlala zibonelela ngemizuzu engama-30 ukuya kwengama-60 yomoya, kuxhomekeke kubungakanani betanki kunye nobunzulu beetanki kunye nobunzulu beetanki.

Ukuhanjiswa komoya kunye nexesha

Ixesha lokuhambisa umoya kuzo zombini iitanki zeSba kunye ne-Scuba ziyahluka ngokusekwe kubungakanani betanki, uxinzelelo, kunye nenqanaba lokuphefumla lomsebenzisi.

1. Iitanki ze-SCBA: Iitanki ze-SCBA ziqhele ukubonelela ngeepesenti ezingama-30 ukuya kwengama-60 zomoya, nangona eli xesha linokwahluka ngokusekwe kubungakanani besilinda kunye nenqanaba lomsebenzi womsebenzisi. Abacimi-mlilo, umzekelo, banokuthatha umoya ngokukhawuleza ngexesha lokusebenza komzimba, ukunciphisa ixesha lomoya wabo.
2. Iitanki zeScuba: Iitanki zeScuba, zisetyenziswa phantsi kwamanzi, zibonelela ngomoya ixesha elide, kodwa eli ngqo elona xesha lixhomekeke kakhulu kubunzulu be-dive kunye nenqanaba lokusetyenziswa kwe-dive. Inzulu i-diver ihamba, eyona moya icinezelweyo iyomoya iba, ekhokelela ekufumaneni umoya. I-scuba eqhelekileyo ye-Scuba ingekabikho phakathi kwemizuzu engama-30 ukuya kwiyure, kuxhomekeke kubungakanani betanki kunye neemeko zedives.

Ukulungiswa kunye neemfuno zokuhlola

Zombini iitanki ze-SCBA kunye ne-scuba zifuna rhoqoUvavanyo lwe-hydrostatickunye nokuhlolwa okubonakalayo ukuqinisekisa ukhuseleko kunye nokusebenza.Itanki ye-carbon fickI-S ivavanywa ngokubanzi qho kwiminyaka emihlanu, nangona oku kunokwahluka ngokuxhomekeke kwimigaqo yendawo kunye nokusetyenziswa. Ngokuhamba kwexesha, iitanki zinokonakala, kwaye ulondolozo oluqhelekileyo lubalulekile kuzo zombini iintlobo zeetanki zokusebenza ngokukhuselekileyo kwiindawo zabo.

1. Uvavanyo lwe-SCBA TAK: Iitanki zeSba, ngenxa yokusetyenziswa kwabo kwiindawo ezinomngcipheko omkhulu, zihlolwe rhoqo kwaye kufuneka zifezekise imigangatho yokhuseleko engqongqo. Umonakalo ovela kubushushu, iimpembelelo, okanye ukuvezwa kwiichemicals kuyinto eqhelekileyo, ke qinisekisa ingqibelelo yesilinda ibalulekile.
2. Uvavanyo lwetanki le-Scuba: Iitanki zeScuba kufuneka zihlolwe rhoqo, ngakumbi imiqondiso ye-corosion okanye ukonakala komzimba. Ngenxa yokuvezwa kwabo kwiimeko zangaphantsi kwamanzi, amanzi etyuwa kunye nezinye izinto zinokubangela ukunxiba, ukhathalelo olufanelekileyo kunye nokuhlolwa rhoqo kubalulekile ukuze kwenziwe i-diver.

Ukuqukumbela

Ngelixa iitanki ze-SCBA kunye ne-scuba zisebenzisa iinjongo ezahlukeneyo, ukusetyenziswa kweI-carbon fiber ye-carbon sylindersiphucule kakhulu iintlobo zeenkqubo. I-carbon fiber ibonelela ngokufana okungafunekiyo, amandla, kunye neepropathi ezilula, ezenza ukuba zibe yinto ekhethiweyo yeetanki eziphezulu zoxinzelelo zokucima umlilo kunye nokuntywila. Iitanki ze-SCBA zakhiwe ukuba zinikezelwe ngomoya okufutshane kwizikhundla ezinobungozi, ezingentla, ngelixa iitanki ze-scuba zenzelwe ukusetyenziswa kwa-qho ngaphantsi kwamanzi. Ukuqonda umahluko phakathi kwezi tanki kubalulekile ekukhetheni izixhobo ezifanelekileyo zemeko nganye eyahlukileyo, ukuqinisekisa ukhuseleko, ukusebenza kakuhle kunye nokusebenza.
