I-Appares yokuphefumula equkethe okuqukethwe (i-SCBA) ibalulekile kubacishimlilo, abasebenzi abahlelayo, nabanye abasebenza ezindaweni eziyingozi.Isilinda se-SCBAUkuhlinzeka ngokuthola umoya okubucayi komoya ophefumulayo ezindaweni lapho umkhathi ungaba nobuthi noma umoya-mpilo. Ukuqinisekisa ukuthi imishini isebenza ngokuphepha nangempumelelo, kubalulekile ukulondolozela nokubuyisela esikhundleniIsilinda se-SCBAnjalo. Kulesi sihloko, sizogxila kukhoI-composite ye-fiber-fiber cylinderS, ikakhulukazi i-carbon fiber, enempilo yenkonzo yeminyaka engu-15. Sizohlola nezidingo zokulungiswa, kufaka phakathi ukuhlolwa kwe-hydrostatic nokuhlola okubukwayo.
Yini iziComposite isilinda se-scba esivinjiwes?
Composite isilinda se-scba esivinjiweIzinto zizakhiwe ngokuyinhloko i-liner engasindi yangaphakathi eyenziwe ngezinto ezinjenge-aluminium noma ipulasitiki, esongelwe ngendlela eqinile eyinhlanganisela efana ne-carbon fiber, i-fiberglass, noma i-kevala. Lawa ma-cylinders alula kakhulu kunensimbi yendabuko noma ama-cylinder we-aluminium kuphela, okwenza balungele ukusetshenziswa ezimweni eziphuthumayo lapho kuhamba khona ukuhamba.I-Carbon Fiber Cylinder SCBAS, ikakhulukazi, kusetshenziswa kabanzi ngoba zinikeza inhlanganisela enhle kakhulu yamandla, isisindo, nokuqina.
Isikhathi sokuphila kweI-Carbon Fiber Cylinder SCBAs
I-Carbon Fiber Cylinder SCBAube nempilo ejwayelekile yeIminyaka engu-15. Ngemuva kwalesi sikhathi, kufanele bathathelwe indawo, kungakhathalekile isimo sabo noma ukubukeka kwabo. Isizathu salolu hlelo lokuphila okuhleliwe kungenxa yokugqoka kancane kancane futhi izinyembezi ezintweni ezihlanganisiwe, ezingasenza lula ngokuhamba kwesikhathi, noma ngabe kungekho monakalo obonakalayo okhona. Kuyo yonke le minyaka, isilinda sivezwa izingcindezi ezahlukahlukene, kufaka phakathi ukuguquguquka kwengcindezi, izici zezemvelo kanye nemithelela engaba khona. LaphoI-composite ye-fiber-fiber cylinderAma-S aklanyelwe ukuphatha le mibandela, ubuqotho bokwenziwa buncipha ngokuhamba kwesikhathi, okungabeka izingozi zokuphepha.
Ukuhlola Okubonakalayo
Enye yezindlela eziyisisekelo nezijwayelekile zokulungisaIsilinda se-SCBAsUkuhlolwa Okubonakalayo. Lokhu kuhlola kufanele kwenziwe ngaphambi nangemva kokusetshenziswa ngakunye ukukhomba noma yiziphi izimpawu ezibonakalayo zomonakalo, njengokuqhekeka, ama-dents, ablossions, noma ukugqwala.
Izinto ezibalulekile okufanele uzibheke ngesikhathi sokuhlola okubukwayo zifaka:
- Ukulimala okungaphezulu: Bheka noma imiphi imifantu ebonakalayo noma ama-chip ku-Cylinder's Outer Composite Wrap.
- Dex: Ama-dents noma i-deformation esimweni sika-cylinde kungakhombisa ukulimala kwangaphakathi.
- Ukugqwala: NgenkathiI-composite ye-fiber-fiber cylinderS bamelana kakhulu nokugqwala kunezinsimbi, noma yiziphi izingxenye zensimbi eziveziwe (njenge-valve) kufanele zihlolwe izimpawu zokugqwala noma ukugqoka.
- Inxusa: Lokhu kwenzeka lapho izingqimba zezinhlanganisela zangaphandle ziqala ukuhlukana ne-liner yangaphakathi, ngokungenisa amandla amasilinda.
Uma kukhona noma yiziphi zalezi zingqinamba zitholakala, isilinda kufanele sisuswe emsebenzini ngokushesha ukuze kuhlolwe okunye.
Izidingo Zokuhlola I-Hydrostatic
Ngaphezu kokuhlolwa okubonakalayo okujwayelekile,Isilinda se-SCBAkumeleUkuhlolwa kweHydrostaticngezikhathi ezithile. Ukuhlolwa kweHydrostatic kuqinisekisa ukuthi isilinda sisengaqukethe ngokuphepha umoya wengcindezelo ephezulu ngaphandle kokufaka engcupheni noma ukuvuza. Ukuhlolwa kubandakanya ukugcwalisa isilinda ngamanzi futhi kusicindezele ngaphezu kwamandla ayo ajwayelekile okuhlola noma yiziphi izimpawu zokunwetshwa noma ukwehluleka.
Imvamisa yokuhlolwa kwe-hydrostatic kuncike ohlwini lwesilinda:
- Ama-Cylinders Ahlanganisiwekudingeka uhlolwe ngokuzikhethela ngokuqinile konkeiminyaka emithathu.
- I-Carbon Fibre-Worper Cylinderskudingeka uhlolwe njaloiminyaka emihlanu.
Ngesikhathi sokuhlolwa, uma isilinda sinwebeka ngaphezu kwemingcele eyamukelekayo noma sibonisa izimpawu zokuxineka noma ukuvuza, zizokwehluleka ukuhlolwa futhi kufanele zisuswe enkonzweni.
Kungani iminyaka eyi-15?
Ungahle uzibuze ukuthi kunganiI-Carbon Fiber Cylinder SCBAIba nempilo ekhethekile yesikhathi seminyaka engu-15, noma ngabe kulungiswa njalo nokuhlolwa. Impendulo ilele endalweni yezinto ezihlanganisiwe. Ngenkathi eqinile, i-carbon fiber enamandla namanye ama-composites futhi ngaphansi kokukhathala nokuwohloka kwesikhathi ngokuhamba kwesikhathi.
Izici zezemvelo ezifana nezinguquko zokushisa, ukuvezwa elangeni (imisebe ye-UV), nemithelela emishini ingahle inciphise izibopho ezisezandleni zezinhlanganisela. Noma lezi zinguquko zingabonakala zibonakale ngokushesha noma zitholakale ngesikhathi sokuhlolwa kwe-hydrostatic, imiphumela engaphezu kwe-15 engaphezu kwe-15 yandisa ingozi yokwehluleka, yingakho i-ejensi yokulawula (ichashaza), umyalo weminyaka yeminyaka engu-15.
Imiphumela yokunganaki ukushintshwa kanye nokunakekelwa
Ukwehluleka ukufaka esikhundleni noma ukugcinaIsilinda se-SCBAkungaholela emiphumeleni emibi, kufaka phakathi:
- Ukwehluleka kwesilinda: Uma kusetshenziswa isilinda esilimele noma esibuthakathaka, kunengozi yayo evuka ngaphansi kwengcindezi. Lokhu kungadala ukulimala okukhulu kumsebenzisi nabanye abaseduze.
- Kuncishiswe ukunikezwa komoya: Isilinda esilimele kungenzeka singakwazi ukubamba inani elidingekayo lomoya, likhawulela umoya otholakalayo womsebenzisi ophefumula ngesikhathi sokuhlenga noma sokucisha umlilo. Ezimweni ezisongela impilo, yonke iminithi yokubala komoya.
- Izinhlawulo Zokulawula: Ezimbonini eziningi, ukuhambisana nemithetho yezokuphepha kuyimpoqo. Kusetshenziswa ama-cylinder aphelelwe yisikhathi noma angenamikhawulo angaholela kwenhlawulo noma ezinye izinhlawulo ezivela kubalawuli bezokuphepha.
Imikhuba emihle kakhuluIsilinda se-SCBAUkulungiswa nokubuyiselwa
Ukuqinisekisa ukuthi ama-cylinders e-SCBA ahlala ephephile futhi asebenza kahle kukho konke impilo yawo, kubalulekile ukulandela lezi zindlela ezinhle kakhulu:
- Ukuhlola okubonakalayo okujwayelekile: Bheka amasilinda nganoma yiziphi izimpawu zomonakalo ngaphambi nangemva kokusetshenziswa ngakunye.
- Ukuhlolwa kweHydrostatic Hydrostatic: Gcina umbhalo walokho lapho isilinda ngasinye sigcina ukuhlolwa futhi siqinisekise ukuthi ihlolwe kabusha ngaphakathi kwesikhathi esidingekayo (njalo eminyakeni emihlanu yeI-Carbon Fibre-Worper Cylinders).
- Isitoreji Esifanele: IsitoloIsilinda se-SCBAendaweni epholile, eyomile, kude nokukhanya kwelanga okuqondile noma okushisa okwedlulele, okungasheshisa ukucekelwa phansi kwezinto ezibonakalayo.
- Buyisela ngesikhathi: Musa ukusebenzisa amasilinda ngaphezu kwesikhathi sawo seminyaka engu-15. Noma ngabe zibonakala zisesimweni esihle, ingozi yokwehluleka inyuka kakhulu ngemuva kwalesi sikhathi.
- Gcina amarekhodi anemininingwane: Gcina izingodo zezinsuku zokuhlola, imiphumela yokuhlolwa kwe-hydrostatic, kanye namashejuli wokushintshwa kwesilinda ukuze aqinisekise ukuhambisana nemigomo nezinqubomgomo zokuphepha.
Ukugcina
Isilinda se-SCBAS, ikakhulukazi i-carbon fiber esongwe, iyingxenye ebalulekile yemishini yalabo abasebenza ezindaweni eziyingozi. Lawa masilinda anikela ngesisombululo esingasindi kodwa esihlala isikhathi eside sokuphatha umoya ocindezelwe. Kodwa-ke, beza nezidingo eziqinile zokugcina kanye nezidingo zokufaka esikhundleni sokuqinisekisa ukuphepha. Ukuhlolwa okubonakalayo okujwayelekile, ukuhlolwa kwe-hydrostatic njalo ngeminyaka emihlanu, nokubuyiselwa ngesikhathi ngemuva kweminyaka engu-15 kuyimikhuba ebalulekile esizaIsilinda se-SCBAethembekile futhi ephephile ukuyisebenzisa. Ngokunamathela kulezi ziqondiso, abasebenzisi bangaqinisekisa ukuthi banokuhlinzekwa komoya abakudingayo lapho ibaluleke kakhulu, ngaphandle kokuyekethisa ukuphepha.
