Ukukhetha amathangi omoya wokuntywila kucishe kube okomuntu siqu njengokuthola izingubo zangaphansi ezintsha. Okusebenzela umuntu oyedwa ngeke kumsebenzele omunye, kungakhathaliseki ukuthi abathengi bazama kanzima kangakanani. Kodwa okuhle ukuthi uma abathengisi sebazi ukuthi hlobo luni lwabathengi abatshuzayo abazobe belwenza, ukukhetha ithangi elifanele ukubanikeza kuzoba mnandi.
Qhubeka ufunda ukuze uhlole izinto ezahlukahlukene amabhizinisi okufanele azicabangele ngaphambi kokuthenga lesi sixhobo esibalulekile sokuntywila. Kodwa ngaphambi kwalokho, ake sibheke isimo semakethe ye-diving air tank.
Okuqukethwe

Ingabe abathengisi kufanele batshale imali emakethe yemishini yokuntywila?
Ngo 2023, the imakethe yemishini ye-scuba diving imali elinganiselwa ku-US $991.78 million. Ngokushesha phambili ku-2024, futhi ikhuphuke yafinyelela ku-US $ 1.047 billion. Futhi qagelani? Imakethe kulindeleke ukuthi ikhule ngesilinganiso sokukhula sonyaka esihlanganisiwe esingu-6.10% (CAGR), sifinyelele ku-$1.501 billion ngo-2030. Yini ebhebhezela lokhu kukhula? Nokho, abantu emhlabeni wonke bazithola benemali ethe xaxa abangayigcina, okusho ukuthi bachitha kakhulu izinto abazilibazisa ezifana ne-scuba diving.
Ngamathuba amahle kangaka okukhula, abathengisi akufanele bangabaze ukutshala imali. Ngo-2022, ingxenye yezokungcebeleka yaba yinto enkulu, ibalwa ngesabelo esikhulu semakethe yomhlaba wonke. INyakatho Melika nayo ihamba phambili kuleli cala, idla ngaphezu kwama-40% emakethe yemishini yokuntywila emanzini ngo-2022, ngokwezibalo zombiko ezingenhla.
Izici eziphezulu amabhizinisi okufanele azicabangele lapho ekhetha amathangi omoya wokuntywila
Uhlobo lwethangi
Uma abathengi sebeshaye ucingo lokuzitholela amathangi oku-diving kunokuba bawaqashe, okulandelayo abazonquma wuhlobo olulungele bona. Amathangi okuntywila ngokuvamile eza ngezakhiwo ezimbili: i-aluminium noma insimbi. Futhi bobabili banezinzuzo zabo.
Amathangi e-aluminium dive
Uma abathengi bengabatshuzi nje abajwayelekile bezokungcebeleka abafuna ithangi elithembekile, aluminium inketho ekhethwayo. Ngokudumile aluminium 80 ithangi, abathengi bazothola umoya ongangehora. Futhi thola lokhu: inesisindo esingamaphawundi angama-31 uma ingenalutho. Kodwa uma isigcwalisiwe, inamakhilogremu angaba ngu-5 we-buoyancy engalungile, okusho ukuthi izogcina abatshuzi bephansi kahle ngesikhathi sokutshuza kwabo.
Ukukhuluma kabanzi ngobuhle, amathangi e-aluminium dive thatha isimo sokungathathi hlangothi noma esihle kancane uma singenalutho, esilungele ukukhuphuka okushelelayo lapho abathengi sebelungele ukuphindela phezulu. Manje, nansi into—uma ithangi le-aluminium lincike kakhulu ekunyakazeni okuhle, abathengi bangase badinge ukuphonsa isisindo esengeziwe ukuze bagcine izinto zilinganisiwe ngesikhathi sokuma kwabo kokuphepha. Kodwa ngaphandle kwalokho, leli thangi liyindlela yokuya kuyo ukuze uthole umuzwa oqinile, olawulwayo wokutshuza.
buhle:
Lamathangi anephansi eliyisicaba, eliwavumela ukuthi ame aqonde ngaphandle kosizo. Amathangi e-aluminium nawo afaneleka kangcono ukutshuza emanzini afudumele. Okungcono nakakhulu, la mathangi ayindinganiso yomhlaba wonke, ngakho abathengi bazothola kulula ukuthola izingxenye kungakhathaliseki ukuthi zikuphi. Ekugcineni, amathangi e-aluminium acishe avikeleke ku-oxidation eyenziwe ngumswakama futhi adinga ukunakekelwa okuncane kunamasilinda ensimbi.
bawo:
Ngeshwa, abathengi abaningi bakhononda mayelana nezici ze-aluminium 80 ezingezinhle ze-buoyancy. Futhi, insimbi eyengeziwe ezansi (ephansi eliyisicaba) ingenza abatshuzi abaningi bazizwe besinda.
Amathangi okuntywila ensimbi
Uma abathengi beqala ukuhlolisisa i-nitty-gritty ye-diving ethuthukisiwe, insimbi ingase ilingane nesitayela sabo kakhulu. Nasi isizathu: amathangi ensimbi iza namazansi ayindilinga, anikeza i-buoyancy elinganiselayo. Nakuba abathengi bezodinga ibhuthi yethangi ukuze bagcine lamathangi e-diving emi eqondile, abaningi bafunga amathangi okuntywila ensimbi ukuthi inkinga ikufanele.
Uma kuqhathaniswa nethangi le-aluminium 80, insimbi engu-80 diving air tanks nesisindo esingamakhilogremu angama-28 uma ingenalutho. Kodwa lapho abathengi bewagcwalisa ngomoya ocindezelweyo, azoba namakhilogremu angu-8 e-buoyancy angemuhle. Futhi lapho lamathangi engenalutho ngaphansi kwamanzi, i-buoyancy yawo izohlala ku-negative 1.7 pounds. Manje, kulapho okuthakasela khona—abatshuzi bezobuchwepheshe bavamise ukuhamba bevundlile ngaphansi kwamanzi. Ngakho-ke, abaningi babo bakhetha amathangi ensimbi ngoba bahlinzeka ngokuqina okulinganiselwe abakudingayo ukuze bangene emanzini ajulile.
buhle:
Ngenkathi i-aluminium iphatha amanzi afudumele, amathangi ensimbi ayinketho ephezulu kakhulu yokuntywila emanzini abandayo. Banikeza izinketho zosayizi abaningi kunezinhlobonhlobo ze-aluminium, okuvumela abathengi ukuthi bakhethe eyodwa ngokuya ngobude nesisindo sabo. Amathangi ensimbi abuye abe nokunyakaza nokulinganisela okungcono kunezinhlobonhlobo ze-aluminium.
bawo:
Nokho, amathangi ensimbi abiza kakhulu kune-aluminium. Futhi abavikelekile ekulimaleni kwe-oxidation kusuka kumswakama, okusho ukuthi bazodinga ukunakekelwa okwengeziwe nokugcinwa.
Usayizi namandla
Amathangi e-scuba ziza ngazo zonke izinhlobo zomumo nosayizi. Kukhona ezinde nezincane, okuhlukile okufushane neziqinile, namamodeli anezansi eziyisicaba noma eziyindilinga. Manje, kubatshuzi abafushane noma izintokazi ezingafuni ukuzizwa sengathi zibambana nethangi labo elingaphansi kwamanzi, amathangi amafushane ayatholakala athe ukuvuleka kancane. Lezi zingane zisiza abathengi abanjalo ukuba bagweme noma yikuphi ukushayisana kwekhanda noma izinqe okungafunwa ngenkathi behlola ukujula.
Noma kunjalo, ukukhetha usayizi tank kwesokudla inomthetho wegolide: ukusetshenziswa komoya komthengi. Uma abathengi bejwayele ukungena emoyeni wabo ogciniwe ngokushesha, bangase bancike ethangini elikhudlwana isikhathi sokuphefumula esengeziwe. Amathangi e-Aluminium 80 ayizinketho ezivame kakhulu nezisebenzayo ezitholakalayo. Zinhle ngokwanele ukuvumela abatshuzi abaningi ukuthi bafinyelele ekujuleni ngaphandle kokuphusha imikhawulo yokuwohloka.
Kodwa-ke, uma abathengi besohlangothini olukhulu noma bechitha isikhathi esiningi belenga ekugcineni, bazofuna okuthile okukhulu aluminium amathangi 80. Abatshuzi abakhulu bavame ukusebenzisa umoya omningi, ngakho-ke ithangi elikhulu emhlane wabo lingashintsha umdlalo. Futhi, abathengi abajabulela ukuhlola ukujula isikhashana bazojabulela umcamelo owengeziwe wokuphepha ohlinzekwa ngamathangi amakhulu. Bheka ishadi lokulinganisa elingezansi ukuze uthole ulwazi olwengeziwe ngamasayizi wethangi lokuntywila namandla.
Isilinganiso sokucindezela
Ngakho, ithangi ngalinye linesilinganiso salo sokucindezela, kodwa amathangi anosayizi abahlukene namandla angaba nesilinganiso esifanayo sokucindezela. Ngakho-ke, sisho ukuthini leso silinganiso sokucindezela uma amathangi enezilinganiso ezifanayo? Hhayi-ke, ikhombisa umfutho womoya ngaphakathi kwethangi lapho abasebenzisi beligcwalisa. Futhi kukhona uhla lwezilinganiso olutholakalayo: ingcindezi ephansi (2,000 kuya ku-2,400 psi), ukucindezela okujwayelekile (3,000 psi), nokucindezela okuphezulu (3,300 kuya ku-3,500 psi).
Amanye amathangi ensimbi anesilinganiso sokucindezela esilandelwa uphawu lokuhlanganisa, njengo-2,400+. Kusho ukuthini lokho? Kusho ukuthi abasebenzisi banegumbi lokunyakazisa, okubavumela ukuthi bagcwalise amathangi anjalo kufikela ku-10% phezu kwengcindezi eshiwo. Ngakho esikhundleni sokuphuma ku-2,400 psi, angakhuphukela ku-2,640 psi, noma amabha angu-188.
Amathangi ensimbi anengcindezi ephezulu okubhukuda nge-scuba mancane futhi aminyene, okuthandwa ngabatshuzi. Kodwa-ke, badinga ukucindezela okuphezulu ukuze bagcwalise ngokugcwele, okwenza kube nzima ukuthola ukugcwaliswa okuphelele. Kungani? Phakathi nenqubo yokugcwalisa, lawa amathangi azoshisa ngenxa yama-molecule omoya acindezelwe. Kodwa njengoba epholile, amathangi anengcindezi ephezulu azokwehlisa umfutho futhi alahlekelwe umoya. Ukugcwalisa ithangi elinomfutho ophezulu kunzima, okuwuhlangothi oluphansi lokulisebenzisa ukutshuza emanzini.
Ukufingqa
Njengoba ukutshuza kuhilela ukujula emanzini, abathengi badinga amathangi omoya ukuze baphefumule ezimweni ezinjalo. Futhi, nakuba izinsiza eziningi zokuqasha zitholakala, abanye abathengi bakhetha ukuba nezimpahla zabo. Eqinisweni, inani labathengi abafuna ukuthenga amathangi omoya wokuntywila leqe lisuka ku-18,100 ngoJanuwari laya ekusesheni okungu-22,000 ngoFebhuwari 2024. Usulungele ukuthatha ingxenye yale makethe? Sebenzisa amathiphu amathathu okuxoxwe ngawo kulesi sihloko ukuze ukhethe amathangi omoya wokuntywila angcono kakhulu ka-2024.
