Pahū ʻo Shenhai
Wehewehe:
ʻO nā lako uila pahū, hōʻailona ʻia e ka hōʻailona “d,” he ʻano maʻamau o nā lako pahū. No nā makahiki he nui, ʻO ke ʻano flameproof ka mea koho mua i ka hoʻomohala ʻana a me ka hoʻohana ʻana i nā mea uila pahū-hōʻoia. ʻO ia mau mea uila flameproof e hilinaʻi i ka palekana pahū, loaʻa i ka ʻenehana hana makua, a hauʻoli i ke ola lawelawe lōʻihi. Hoʻohana nui ʻia lākou ma nā wahi pōʻino me nā ʻano hui like ʻole o ke kinoea-ea. Eia naʻe, ma muli o ka pale ahi hale kūkulu, ʻano kaumaha kēia mau mea hana.
Kumu o ka Pale Pahū:
ʻO ka hana palekana a me ka pahū ʻana o kēia ʻano mea uila e hōʻoia ʻia e kahi pahu i kapa ʻia ʻo ka “pā pale ahi.”
A “pā pale ahi” hiki i nā hui kinoea-ea hoʻopau ke puhi a pahū i loko o ka pahu akā pale i nā huahana pahū mai ka wāwahi ʻana i ka pahu a i ʻole ka pakele ʻana ma nā ala āpau i waho e hiki ke hoʻā i nā hui pahū a puni.. E like me ka lōʻihi o ka ʻili kiʻekiʻe mahana wela ʻAʻole ʻoi aku ka nui o ka pā i ka papa wela no kāna hui i manaʻo ʻia, ʻaʻole e lilo ka hāmeʻa i kumu hoʻāla no ka hui ʻana o ke ea pahū a puni.
ʻO kēia ke ʻano o ka hana ʻana o nā lako uila pale ahi.
ʻO ka hoʻomaopopo ʻana i kēia kumu, hiki iā mākou ke hoʻoholo i ka pahu o nā mea uila flameproof pono e loaʻa ka ikaika mechanical e kū i ke kaomi pahū i hana ʻia i loko me ka loaʻa ʻole o ka deformation nui a i ʻole ka pōʻino.. ʻO nā ʻokoʻa ma waena o nā ʻāpana o kahi pā ahi, e hana ana i na auwai mai loko a waho, Pono e loaʻa nā ana mechanical kūpono e hiki ke hōʻemi a pale aku paha i ka pakele o nā huahana pahū. ʻO kēia ala, puhi ana o ka pahū pale ʻia ka hui ʻana o ke ea a puni ka mea hana. Hoʻokaʻawale ʻia nā pae pale pahū no nā mea uila flameproof i ʻekolu papa: IIA, IIB, a me IIC. Hiki ke hoʻokaʻawale ʻia nā pae palekana o nā mea hana i ʻekolu papa: a, b, a c, hōʻike pinepine ʻia ma ka hana like: Lako o ka Hui I, ʻO Ma a me Mb; Lako o ka Hui II, Ua ʻōlelo ʻo Ga, ʻO Gb, a me Gc.
ʻO ka pā o lako uila pahū pono e hana ʻia mai nā mea me ka ikaika mechanical maikaʻi, e like me ka pā kila, hao hao, alumini alumini, huila keleawe, kila kohu ʻole, a me ka ʻenekinia plastik. Pono e hoʻokō ka ikaika a me nā ʻāpana āpau i nā koi kūpono o GB3836.2—2010 Explosive Atmospheres Part 2: ʻO nā mea hana i pale ʻia e nā pā pale ahi.
