He aha nā pahu SCBA i hoʻopiha ʻia me?

pahu hana hanu paʻa ponoʻī (SCBA).s he mau lako palekana koʻikoʻi i hoʻohana ʻia i nā ʻoihana like ʻole, me ke ahi ahi, nā hana hoʻopakele, a me ka mālama ʻana i nā mea weliweli. Hāʻawi kēia mau pahu i ka hāʻawi ʻana i ka ea hanu i nā mea hoʻohana pono e hana i nā kaiapuni kahi i haumia ai ka ea a i ʻole ka haʻahaʻa haʻahaʻa o ka oxygen. Hoʻomaopopo i ka meapahu SCBAs ua hoʻopiha ʻia me nā mea i hoʻohana ʻia no ke kūkulu ʻana iā lākou he mea nui no ka mahalo i kā lākou hana a me ka hōʻoia ʻana i kā lākou hoʻohana pono ʻana i nā pōpilikia.

He ahaʻO ka pahu SCBAs Loaʻa

pahu SCBAs, i ʻike ʻia he cylinders, ua hoʻolālā ʻia e mālama a hāʻawi i ka ea paʻa a i ʻole ka oxygen i ka mea nāna e hoʻohana. Eia kahi nānā kikoʻī i nā mea i loko a me ke kūkulu ʻana o kēia mau pahu.

1. Ea Komi

ʻO ka hapa nuipahu SCBAs ua hoopihaia me ka ea compressed. ʻO ka ea kaomi ʻia ka ea i kaomi ʻia i kahi kiʻekiʻe ma mua o ke kaomi lewa. Hāʻawi kēia kaomi ʻana i ka nui o ka ea e mālama ʻia i loko o kahi pahu liʻiliʻi liʻiliʻi, hiki ke hoʻohana ʻia i nā kūlana like ʻole. Ea kōmi ʻia i lokopahu SCBAs ka mea maʻamau o:

• Oxygen:Ma kahi o 21% o ka ea he oxygen, ʻo ia ka pakeneka like i loaʻa ma ka lewa ma ka ʻilikai.
• Nitrogen a me nā kinoea ʻē aʻe:ʻO ke koena he 79% o ka nitrogen a me ka nui o nā kinoea ʻē aʻe i loaʻa i ka lewa.

ʻO ka ea kōmi i lokopahu SCBAHoʻomaʻemaʻe ʻia ʻo s no ka wehe ʻana i nā haumia, e hōʻoia i ka palekana no ka hanu ʻana i loko o nā wahi haumia.

2. Oxygen paʻa

I kekahi mau ʻāpana SCBA kūikawā, hoʻopiha ʻia nā pahu me ka oxygen compressed maʻemaʻe ma mua o ka ea. Hoʻohana ʻia kēia mau ʻāpana i nā hiʻohiʻona kikoʻī kahi e pono ai ke kiʻekiʻe kiʻekiʻe o ka oxygen a i ʻole kahi e hoʻopilikia nui ʻia ai ka maikaʻi o ka ea. Hoʻohana pinepine ʻia ka oxygen compressed i:

• Lapaʻau ulia pōpilikia:Kahi e pono ai ka oxygen maʻemaʻe no nā poʻe maʻi me nā pilikia hanu.
• Nā hana kiʻekiʻe kiʻekiʻe:Ma kahi o ka pae o ka oxygen i haʻahaʻa, a ʻoi aku ka maikaʻi o ka oxygen kiʻekiʻe.

Kūkulu ʻia oʻO ka pahu SCBAs

pahu SCBAs ua hoʻolālā ʻia e kū i nā kaomi kiʻekiʻe a me nā kūlana paʻakikī. ʻO ke koho ʻana i nā mea i hoʻohana ʻia i ke kūkulu ʻana i kēia mau pahu he mea koʻikoʻi no kā lākou hana a me ka palekana.ʻO ka pahu kalapona hui pūs he koho kaulana ma muli o ko lākou mau waiwai maikaʻi. Eia ka nānā pono ʻana i kēia mau mea:

1. Paʻa Paʻa Hui Pū ʻIa Carbons

ʻO ka pahu kalapona hui pūs hoʻohana nui ʻia i nā ʻōnaehana SCBA ma muli o ko lākou ikaika a me nā waiwai māmā. ʻO nā mea nui o kēia mau cylinders:

• Laina loko:ʻO ka liner o loko o ka cylinder, i hana maʻamau ʻia mai nā mea like me ka alumini a i ʻole ka plastic, e paʻa i ka ea a i ʻole oxygen.
• ʻO ka uhi ʻana o ka carbon fiber:Hana ʻia ka ʻaoʻao o waho o ka cylinder mai ka carbon fiber composite material. ʻO ka carbon fiber kahi mea ikaika a māmā e hāʻawi ana i ka ratio ikaika-a-kaumaha kiʻekiʻe a me ke kūpaʻa ʻana i ka hopena a me ka corrosion.

Pono oPaʻa Paʻa Hui Pū ʻIa Carbons:

• Māmā: ʻO ka pahu kalaponaʻoi aku ka maʻalahi o ka hoʻohālikelike ʻana i ke kila kahiko a i ʻole nā ​​pahu alumini. ʻO kēia ka mea e maʻalahi ai ka lawe ʻana a me ka mālama ʻana, ʻo ia ka mea nui i nā kūlana kiʻekiʻe e like me ke ahi ahi a i ʻole nā ​​hana hoʻopakele.
• Ka ikaika kiʻekiʻe:ʻOiai he māmā,puʻupuʻu huikau kalaponas ikaika loa a hiki ke pale aku i nā puʻe kiʻekiʻe. ʻO kēia ka mea e hiki ai i ka cylinder ke hoʻopaʻa palekana i ka ea i hoʻopaʻa ʻia a i ʻole oxygen me ka pilikia ʻole o ka haki.
• Ka lōʻihi:Kūleʻa ka carbon fiber i ka corrosion a me ka pōʻino mai nā kumu kaiapuni. Hoʻohui kēia i ka lōʻihi o nā cylinders, e hilinaʻi iā lākou i nā kūlana paʻakikī.
• Pono:ʻO ka hoʻolālā opuʻupuʻu kalaponas hiki iā lākou ke mālama i ka ea a i ʻole ka oxygen ma kahi liʻiliʻi liʻiliʻi, e hāʻawi ana i nā mea hoʻohana i kahi mea hanu ʻoi aku ka paʻakikī a maikaʻi.

2. Nā Mea Hana ʻē aʻe

• Aluminum Liner:ʻO kekahipahu SCBAs hoʻohana i kahi liner alumini, ʻoi aku ka māmā ma mua o ke kila a hāʻawi i ke kūpaʻa maikaʻi i ka corrosion. Hoʻopili pinepine ʻia kēia mau pahu me kahi mea hoʻohui, e like me ka fiberglass a i ʻole ke kalapona kalapona, e hoʻonui ai i ko lākou ikaika.
• nā pahu kila:Hana ʻia nā pahu kuʻuna SCBA mai ke kila, ʻoi aku ka ikaika akā ʻoi aku ke kaumaha ma mua o ka alumini a i ʻole nā ​​mea hoʻohui. Hoʻohana mau ʻia nā pahu kila i kekahi mau noi akā ke hoʻololi mālie ʻia nei e nā mea ʻoi aku ka māmā.

Ka mālama a me ka palekana

E hōʻoia ana i kapahu SCBAs ua hoʻopiha pololei ʻia a mālama pono ʻia he mea koʻikoʻi no ka palekana a me ka hana:

• Nānā mau: pahu SCBAPono e nānā mau ʻia nā hōʻailona o ka ʻaʻahu a i ʻole ka pōʻino. Hoʻopili kēia i ka nānā ʻana i nā niho, nā māwae, a i ʻole nā ​​​​pilikia ʻē aʻe e hiki ke hoʻololi i ka pono o ka pahu.
• Hoʻāʻo Hydrostatic: pahu SCBAPono lākou e hoʻāʻo hydrostatic i kēlā me kēia manawa e hōʻoia i hiki iā lākou ke pale i nā koʻikoʻi kiʻekiʻe i hoʻolālā ʻia no lākou. ʻO kēia ka hoʻopiha ʻana i ka pahu me ka wai a me ke kaomi ʻana iā ia e nānā i nā leaka a i ʻole nā ​​nāwaliwali.
• Hoʻopiha kūpono:Pono e hoʻopiha ʻia nā pahu e nā poʻe loea i hoʻomaʻamaʻa ʻia e hōʻoia i ka paʻi ʻana o ka ea a i ʻole ka oxygen i ke kaomi kūpono a palekana ka pahu e hoʻohana.

Ka hopena

pahu SCBAHe kuleana koʻikoʻi ia i ka hāʻawi ʻana i ka ea hanu a i ʻole ka oxygen i nā wahi pōʻino. ʻO ke koho ʻana i nā mea no kēia mau pahu ka hopena nui i kā lākou hana.ʻO nā puʻupuʻu huikau carbon fiberua lilo i koho kaulana ma muli o ko lākou māmā, ikaika kiʻekiʻe, a me ka lōʻihi. Hāʻawi lākou i nā pōmaikaʻi nui ma mua o ke kila kila a i ʻole nā ​​pahu pahu alumini, me ka maʻalahi o ka mālama ʻana a me ka palekana palekana. ʻO ka mālama mau ʻana a me ka mālama pono ʻana i kēia mau pahu e hōʻoia i ko lākou hilinaʻi a me ka pono, e hana pono iā lākou no ka palekana i nā ʻano pilikia a me nā noi ʻoihana.
