I-SCBA Cylinder Maintenance: Nini Futhi Kanjani Ukushintsha Amasilinda Agoqwe Nge-Fiber Ehlanganisiwe

I-Self-Contained Breathing Apparatus (SCBA) ibalulekile kubacimi bomlilo, abasebenzi bokutakula, nabanye abasebenza ezindaweni eziyingozi.I-SCBA cylinders ihlinzeka ngokuhlinzekwa okubalulekile komoya ophefumulayo ezindaweni lapho umkhathi ungase ube nobuthi noma untule umoya-mpilo. Ukuqinisekisa ukuthi okokusebenza kusebenza ngokuphepha nangempumelelo, kubalulekile ukunakekelwa nokushintshwaI-SCBA cylinders njalo. Kulesi sihloko, sizogxila kukhoisilinda esiyinhlanganisela yefiber-gongwes, ikakhulukazi i-carbon fiber, enempilo yesevisi yeminyaka eyi-15. Sizophinde sihlole izidingo zokunakekela, okuhlanganisa ukuhlolwa kwe-hydrostatic nokuhlola okubukwayo.

Yini iziI-Composite Fiber-Egoqwe I-SCBA Cylinders?

Isilinda se-SCBA esiyinhlanganisela yefayibha egoqwes ngokuyinhloko akhiwe ngomugqa wangaphakathi ongasindi owenziwe ngezinto ezifana ne-aluminium noma ipulasitiki, esongwe ngento eqinile eyinhlanganisela efana ne-carbon fibre, i-fiberglass, noma i-Kevlar. Lawa masilinda alula kakhulu kunensimbi evamile noma amasilinda e-aluminium kuphela, okuwenza alungele ukusetshenziswa ezimeni eziphuthumayo lapho ukuhamba kubalulekile khona.Isilinda se-SCBA esigoqelwe nge-fibers, ikakhulukazi, asetshenziswa kakhulu ngoba anikeza inhlanganisela engcono kakhulu yamandla, isisindo, nokuqina.

Ukuphila kweI-Carbon Fiber-Egoqwe I-SCBA Cylinders

Isilinda se-SCBA esigoqelwe nge-fibers zinesikhathi sokuphila esijwayelekile seIminyaka engu-15. Ngemuva kwalesi sikhathi, kufanele zishintshwe, kungakhathaliseki ukuthi zinjani isimo noma ukubukeka kwazo. Isizathu salokhu kuphila okunqunyiwe kungenxa yokuguga kancane kancane ezintweni eziyinhlanganisela, ezingaba buthaka ngokuhamba kwesikhathi, ngisho noma kungekho monakalo obonakalayo okhona. Ngokuhamba kweminyaka, isilinda sichayeka ekucindezelekeni okuhlukahlukene, okuhlanganisa nokuguquguquka kwengcindezi, izici zemvelo, nemithelela engaba khona. Ngenkathiisilinda esiyinhlanganisela yefiber-gongwes ziklanyelwe ukuphatha lezi zimo, ubuqotho bezinto ezibonakalayo buyehla ngokuhamba kwesikhathi, okungadala ubungozi bokuphepha.

Ukuhlola Okubonakalayo

Enye yezindlela eziyisisekelo nezivamile zokunakekelaI-SCBA cylinders yikoukuhlolwa okubonakalayo. Lokhu kuhlola kufanele kwenziwe ngaphambi nangemva kokusetshenziswa ngakunye ukuze kubonakale noma yiziphi izimpawu zomonakalo ezibonakalayo, njengokuqhekeka, ukubola, imihuzuko, noma ukugqwala.

Izinto ezibalulekile okufanele uzibheke ngesikhathi sokuhlolwa okubonakalayo zifaka:

• Ukulimala kobuso: Hlola noma yikuphi ukuqhekeka okubonakalayo noma ama-chips ekugoqeni kwenhlanganisela yangaphandle yesilinda.
• Amazinyo: Amazinyo noma ukuwohloka kwesimo sesilinda kungabonisa umonakalo wangaphakathi.
• Ukugqwala: Ngenkathiisilinda esiyinhlanganisela yefiber-gongweZiyakwazi ukumelana nokugqwala kunezensimbi, noma yiziphi izingxenye zensimbi eziveziwe (njengevalvu) kufanele zihlolwe ukuthi azikho izimpawu zokugqwala noma ukuguga.
• I-Delamination: Lokhu kwenzeka lapho izendlalelo eziyinhlanganisela yangaphandle ziqala ukuhlukana nolayini ongaphakathi, okungenzeka okona amandla esilinda.

Uma kutholakala noma iyiphi yalezi zinkinga, isilinda kufanele sisuswe enkonzweni ngokushesha ukuze siphinde sihlolwe.

Izidingo Zokuhlola I-Hydrostatic

Ngaphezu kokuhlolwa okubonakalayo okuvamile,I-SCBA cylinders kumele idluleukuhlolwa kwe-hydrostaticngezikhathi ezimisiwe. Ukuhlolwa kwe-Hydrostatic kuqinisekisa ukuthi isilinda sisengaqukatha ngokuphephile umoya onomfutho omkhulu ngaphandle kokubeka engcupheni yokuqhuma noma ukuvuza. Ukuhlola kuhilela ukugcwalisa isilinda ngamanzi nokusicindezela ngaphezu kwamandla aso avamile okusebenza ukuze kuhlolwe noma yiziphi izimpawu zokunwetshwa noma ukwehluleka.

Imvamisa yokuhlolwa kwe-hydrostatic incike ohlotsheni lwesilinda:

• Amasilinda ahlanganiswe nge-fiberglasskudingeka ihlolwe i-hydrostatic njaloiminyaka emithathu.
• Isilinda esigoqwe nge-carbon fibreskudingeka ihlolwe njaloiminyaka emihlanu.

Ngesikhathi sokuhlolwa, uma isilinda sikhula ngaphezu kwemikhawulo eyamukelekayo noma sibonisa izimpawu zokucindezeleka noma ukuvuza, sizofeyila ukuhlolwa futhi kufanele sikhishwe enkonzweni.

Kungani iminyaka engu-15?

Ungase uzibuze ukuthi kunganiIsilinda se-SCBA esigoqelwe nge-carbon fibreIba neminyaka eyi-15 yokuphila ethile, ngisho nokugcinwa nokuhlolwa okuvamile. Impendulo ilele esimweni sezinto eziyinhlanganisela. Nakuba kunamandla ngendlela emangalisayo, i-carbon fibre nezinye izinhlanganisela nazo zingaphansi kokukhathala nokonakala ngokuhamba kwesikhathi.

Izici zemvelo ezifana nokushintsha kwezinga lokushisa, ukuchayeka emisebeni yelanga (imisebe ye-UV), kanye nomthelela wokusebenza kungenza kancane kancane izibopho zezendlalelo eziyinhlanganisela. Ngisho noma lezi zinguquko zingase zingabonakali ngokushesha noma zingabonakali ngesikhathi sokuhlolwa kwe-hydrostatic, imiphumela eqoqiwe eminyakeni eyi-15 ikhulisa kakhulu ingozi yokwehluleka, yingakho izinhlangano ezilawulayo, njengoMnyango Wezokuthutha (DOT), zigunyaza ukushintshwa kwe-15- uphawu lonyaka.

Imiphumela Yokuziba Ukushintshwa Nokugcinwa

Yehlulekile ukufaka esikhundleni noma ukunakekelaI-SCBA cylinders kungaholela emiphumeleni eyinhlekelele, ehlanganisa:

1. Ukuhluleka kwesilinda: Uma kusetshenziswa isilinda esilimele noma esibuthakathaka, kunengozi yokuthi siqhume ngaphansi kwengcindezi. Lokhu kungabangela ukulimala okubi kumsebenzisi nakwabanye abaseduze.
2. Ukunikezwa komoya okwehlisiwe: Isilinda eyonakele ingase ingakwazi ukubamba inani lomoya elidingekayo, ikhawulele umoya ophefumulayo womsebenzisi otholakalayo phakathi nomsebenzi wokuhlenga noma wokucisha umlilo. Ezimweni ezisongela ukuphila, yonke iminithi yomoya ibalulekile.
3. Izijeziso zokulawula: Ezimbonini eziningi, ukuthobela imithetho yokuphepha kuyisibopho. Ukusebenzisa amasilinda aphelelwe yisikhathi noma angahloliwe kungaholela ezinhlawulweni noma kwezinye izinhlawulo ezivela kubalawuli bezokuphepha.

Imikhuba Engcono Kakhulu yeI-SCBA CylinderIsondlo kanye Nokushintshwa

Ukuqinisekisa ukuthi amasilinda e-SCBA ahlala ephephile futhi esebenza ngesikhathi sakho sonke sokuphila, kubalulekile ukulandela lezi zindlela ezihamba phambili:

1. Ukuhlolwa okuvamile okubonakalayo: Hlola amasilinda ukuze uthole noma yiziphi izimpawu zomonakalo ngaphambi nangemva kokusetshenziswa ngakunye.
2. Ukuhlolwa kwe-hydrostatic okuhleliwe: Gcina umbhalo walokho ukuthi isilinda ngasinye sagcina nini ukuhlolwa futhi uqinisekise ukuthi sihlolwa kabusha ngesikhathi esibekiwe (njalo eminyakeni emihlanuisilinda esigoqelwe nge-carbon fibres).
3. Isitoreji esifanele: IsitoloI-SCBA cylinderendaweni epholile, eyomile, kude nelanga eliqondile noma amazinga okushisa aphezulu, okungasheshisa ukuwohloka kwempahla.
4. Faka esikhundleni ngesikhathi: Ungawasebenzisi amasilinda angaphezu kweminyaka eyi-15 yokuphila kwawo. Ngisho noma zibonakala zisesimweni esihle, ingozi yokwehluleka iyanda kakhulu ngemva kwalesi sikhathi.
5. Gcina amarekhodi anemininingwane: Gcina amalogi ezinsuku zokuhlolwa, imiphumela yokuhlolwa kwe-hydrostatic, namashejuli okushintsha isilinda ukuze uqinisekise ukuthotshelwa kwemithetho nezinqubo zokuphepha.

Isiphetho

I-SCBA cylinderama-s, ikakhulukazi lawo asongwe nge-carbon fibre, ayisisetshenziswa esibalulekile salabo abasebenza ezindaweni eziyingozi. Lawa masilinda anikeza isisombululo esingasindi kodwa esiqinile sokuthwala umoya ocindezelwe. Kodwa-ke, beza nezidingo eziqinile zokunakekelwa nokushintshwa ukuze kuqinisekiswe ukuphepha. Ukuhlolwa okuvamile okubukwayo, ukuhlolwa kwe-hydrostatic njalo eminyakeni emihlanu, kanye nokushintshwa okufika ngesikhathi ngemva kweminyaka eyi-15 kuyizinqubo ezibalulekile ezisiza ukugcinaI-SCBA cylinders enokwethenjelwa futhi iphephile ukuyisebenzisa. Ngokuthobela le mihlahlandlela, abasebenzisi bangaqinisekisa ukuthi banomoya abawudingayo uma kubaluleke kakhulu, ngaphandle kokuphazamisa ukuphepha.
