Ungawafunda Kanjani Umthamo wesilinda we-SCBA: Ukuqonda Isikhathi Sokusebenza Sokusebenza Kwe-Carbon fiber Cylinders

I-Cylindes yokuphefumula equkethe okuqukethwe (SCBA)S bagxeka ukuhlinzeka ngomoya ophefumulayo kubacishimlilo, abasebenzi abahlelayo, kanye nabanye abasebenzi abasebenza ezindaweni ezinobungozi. Ukwazi isikhathi esingakananiIsilinda se-SCBAKuzohlala ngesikhathi kusetshenziswa kubalulekile ekuhleleni imisebenzi kanye nokuqinisekisa ukuphepha. Isikhathi sokusebenza sesilinda sincike kwivolumu yaso, ingcindezi, kanye nesilinganiso sokuphefumula somsebenzisi. Le ndatshana izohamba kuwe ngendlela yokubala umthamo weIsilinda se-SCBA, usebenzisa ifomula elula, ngokunaka okukhethekileI-Carbon fiber Composite CylinderS, esetshenziswa kabanzi ngenxa yokungasindi namandla abo.

Isilinda se-SCBAIzisekelo: ivolumu nengcindezi

Isilinda se-SCBAIsitolo esicindezelwe umoya ngokucindezela okuphezulu, ngokujwayelekile kulinganiswe ngemigoqo noma kumakhilogremu nge-inch (PSI). Ivolumu yomoya ngaphakathi kwesilinda ivame ukuvezwa ngamalitha. Izici ezimbili eziphambili ezinquma ukuthi kungakanani umoya otholakalayo yile:

• Ivolumu yesilinda: Lokhu kungusayizi wangaphakathi wesilinda, esivame ukuvezwa ngamalitha (isib., 6.8-litre noma 9-litre).
• Ukucindezela kwesilinda: Ingcindezi lapho umoya ugcinwe khona umoya, ngokuvamile phakathi kwebha ye-200 ne-300 yeIsilinda se-SCBAs.

I-Carbon fiber Composite CylinderS zithandwa ezinhlelweni ze-SCBA ngoba zinikeza umthamo ophakeme wengcindezi (kufika kubha engu-300) ngenkathi zilula kakhulu kunensimbi yendabuko noma amasilinda we-aluminium. Lokhu kubenza balungele izimo lapho abasebenzisi badinga ukuhambisa khona ngokushesha noma ngezikhathi ezengeziwe.

The ifomula yokubala ubude be-SCBA

Isikhathi sokusebenza seIsilinda se-SCBAingabalwa kusetshenziswa ifomula elandelayo:

• I- "40" kwifomula imele isilinganiso esilinganiselwe somuntu ngaphansi kwezimo zomsebenzi ezilinganiselayo. Lesi silinganiso singahluka ngokuya ngokuthi umsebenzisi usebenza kanzima kangakanani, kepha amalitha angama-40 ngomzuzu (l / min) uyisibalo esijwayelekile.
• I- "-10" ekugcineni kwefomula ingumugqa wokuphepha, ukuqinisekisa ukuthi umsebenzisi unesikhathi sokuphuma endaweni eyingozi ngaphambi kokuba umoya uphele ngokuphelele.

Ukubalwa kwesibonelo:

Masibala isikhathi sokusebenza se-6.8-litreI-Carbon fiber SCBA Cylinder, inqotshwe kubha engu-300.

Kulesi sibonelo,Isilinda se-SCBAizohlinzeka ngemizuzu ecishe ibe ngu-35 yomoya ophefumulayo ngaphambi kokudinga ukushintshwa noma ukugcwaliswa. Lesi sibalo sithatha umsebenzi olinganiselayo ngokomzimba, futhi isikhathi sangempela sokusetshenziswa singahluka uma umsebenzisi azikhandla ngokwengeziwe noma ngaphansi.

Izici ziyavumaningaIsilinda se-SCBAIsikhathi sisonke

Ngenkathi ifomula ihlinzeka ngesilinganiso esiyisisekelo, izici eziningana zingathonya

isikhathi sangempela seIsilinda se-SCBAukusetshenziswa. Ukuqonda lezi eziguquguqukayo kubalulekile ekuqinisekiseni ukusebenza okuphephile.

1. Izinga lokuphefumula

Ifomula ithatha inyama ephakathi

Izinga le-Hing le-40 l / min, elihambelana nomsebenzi olinganiselayo. Eqinisweni, isilinganiso sokuphefumula singashintshashintsha ngokuya ngomsebenzi womsebenzisi:

• Umsebenzi ophansi: Uma umsebenzisi ephumule noma enza umsebenzi wokukhanya, izinga lokuphefumula lingaphansi, cishe ngo-20-30 l / min, elizokwengeza isikhathi sesilinda.
• Umsebenzi ophakeme: Ngesikhathi sokuzivocavoca okusindayo, njengokulwa nemililo noma ukutakula abantu, amanani okuphefumula angakhuphuka abe ngu-50-60 l / min noma ngaphezulu, anciphise isikhathi sesilinda.

2. Ukucindezela kwesilinda

Ama-cylinder aphezulu wengcindezi ahlinzeka ngomoya owengeziwe ngevolumu efanayo.Isilinda se-carbon fiberNgokuvamile asebenze izingcindezi ezifika kubha ye-300, uma kuqhathaniswa namasilinda ensimbi noma we-aluminium, okungakhawulelwa ku-200 bar. Ingcindezi ephezulu ivumelaisilinda se-carbon fiberS ukubamba umoya omningi ephaketheni elincane, elikhanyayo, elelula isikhathi sokusebenza.

3. Ukuphepha margin

I-margin yokuphepha eyakhiwe kwifomula (-10 imizuzu) iqinisekisa ukuthi

Umsebenzisi akaphelelwa umoya ngenkathi esendaweni enobungozi. Kubalulekile ukuhlonipha lesi buffer lapho kubalwa isikhathi sokusebenza nokuhlela komoya, ikakhulukazi ezimweni lapho indlela yokuphuma ingathatha imizuzu embalwa ukuwela.

Indima yeI-Carbon fiber Composite Cylinders

I-Carbon fiber Composite CylinderUba yikhethelo elikhethwayo lezinhlelo ze-SCBA ngenxa yedizayini yazo engasindi kanye nekhono lokubamba izingcindezi eziphakeme. Qhathanisa nensimbi ne-aluminium cyliders,isilinda se-carbon fiberS unikele ngezinzuzo eziningana:

• Isisindo: Isilinda se-carbon fiberS light lighting kakhulu kunensimbi, okwenza kube lula ukuthwala futhi kunciphise ukukhathala komsebenzisi ngesikhathi semisebenzi eyengeziwe.
• Ingcindezi ephakeme: Zingagcwaliswa ekucindezelweni kuze kube yi-300 bar, enikeza umoya omningi ngaphandle kokukhulisa usayizi we-cylinder.
• Ukuqina: Ama-composites e-carbon fiber aqine kakhulu, akwazi ukubekezelela izingcindezi eziphakeme ngenkathi futhi amelana nomthelela kanye nezici zezemvelo.

Idizayini engasindi ibaluleke kakhulu ukutakula abasebenzi abadinga ukuhlala benza iselula ngenkathi bephethe eminye imishini, njengamathuluzi okucisha izicishamlilo noma amagiya ezokwelapha. Naphezu kwezinzuzo zabo,isilinda se-carbon fiberAma-s aza nezinye izidingo ezengeziwe zokulungiswa, njengokuhlolwa okujwayelekile kwe-hydrostatic ukuqinisekisa ukuthi bahlala bephephile ngaphansi kwengcindezi.

Ukuhlolwa kwe-hydrostatic futhiIsilinda se-SCBAUkuhlalisa

Ukugcina ukwethenjwa kweIsilinda se-SCBAS, kufaka phakathi amamodeli e-carbon fiber, ukulungiswa okujwayelekile kubalulekile. Lokhu kufaka phakathi:

• Ukuhlola Okubonakalayo: Bheka umonakalo, njengokuqhekeka noma ama-dents, ngaphambi kokusetshenziswa ngakunye.
• Ukuhlolwa kweHydrostatic: I-Carbon fiberIsilinda se-SCBAImvamisa idinga ukuhlolwa kwe-hydrostatic njalo ngeminyaka emihlanu ukuqinisekisa ukuthi bangakwazi ukuphatha izingcindezi eziphakeme ezibandakanyekile. Lokhu kuhlola kuhlola noma yikuphi ukunwetshwa kusilinda esingakhombisa ukuncipha kwezinto ezibonakalayo.
• Ukubeka endaweni: Noma ngokulungiswa okufanele,I-Carbon fiber SCBA CylinderIba nempilo yempilo ephelele, imvamisa eneminyaka eyi-15, ngemuva kwalokho kufanele ithathelwe indawo.

Ukugcina

Ukwazi ukuthi ubala kanjani umthamo kanye nesikhathi sokusebenza seIsilinda se-SCBAs

kubalulekile kunoma ngubani othembele kulo la madivayisi ezindaweni eziyingozi. Kusetshenziswa ifomula(Ivolumu × ingcindezi) / 40 - 10, wena can ukulinganisa isikhathi esitholakalayo kunoma yisiphi isilinda esinikeziwe, sikhumbula ukuthi amanani okuphefumula, ingcindezi, kanye nokuphepha ama-margins wonke adlala indima ngesikhathi sokugcina.

I-Carbon fiber Composite CylinderS, ngomklamo wabo ongasindi futhi nekhono lokubamba izingcindezi eziphakeme, kuyindlela ethandwayo yezinhlelo ze-SCBA. Banikela ngezikhathi ezinde zokusebenza kanye nokuhamba okuthuthukile ngokuqhathaniswa namasilinda wensimbi noma aluminium. Kodwa-ke, ukulungiswa okujwayelekile, kufaka phakathi ukuhlolwa okubukwayo kanye nokuhlolwa kwe-hydrostatic, kubalulekile ukuqinisekisa ukuthi lawo masilinda ahlala ephephile futhi esebenza kahle kuyo yonke impilo yakhe yenkonzo.

Ukuqonda lezi zici zeIsilinda se-SCBAAmandla azosiza ekuqinisekiseni ukusetshenziswa okuphephile futhi okusebenzayo ezindaweni eziyinselele, lapho yonke iminithi yomoya ophefumulayo ingenza umehluko.
