ʻO ka pahu puʻupuʻu pahū-hōʻoiaʻiʻo puʻupuʻu galvanised no ka pahu uwahi hale hana
wehewehe:
1、ʻO ka mea hoʻoheheʻe waho o ka mea peʻa he koho: ka pepa galvanized, 201 stainless steel, 304 stainless steel.
2、Explosion-hōʻoiaʻino puʻe peʻahi mea nui kūpono no ka flammable a me ka pahū kinoea kaiapuni, humid a me ka 'oʻoleʻa kaiapuni.ʻO ka hana pahū pahū hilinaʻi, ka nui o ka ea a me ka leo haʻahaʻa.
3、 Hiki ke hoʻopilikino ʻia ka nui Fan
4、Ua hana ʻia ka peʻahi pā e ka hoʻoheheʻe ʻana i hoʻokahi manawa, he nani a paʻa.ʻO ka hoʻolālā ʻano o ka lau kūikawā e hōʻoia i ka nui o ka ea a ʻaʻohe deformation.
5、Pahū-hōʻoia papa Exd II BT4 Pahū-hōʻoiaʻiʻo kaʻa kaʻa, lōʻihi a me ka ikaika, kaʻa kaʻa mākaʻikaʻi IP 55, insulation pae: F pae.
6、Ua hana ʻia ka huila alumini a me ke kihi ʻili i ka alumini magnesium alloy, me ka paona māmā, paʻakikī maikaʻi, a ʻaʻole maʻalahi e hōʻino.
ʻO ke ʻano o ka Explosion-proof Grade Exd II BT4:
ʻO ka wehewehe ʻana o nā mea pahū: nā lako uila ʻaʻole e hoʻāla ʻia i loko o ke kaiapuni pahū a puni ma lalo o nā kūlana i kuhikuhi ʻia.
Hiki ke ʻike ʻia ke ʻano pahū a me nā manawa kūpono o ka huahana mai ka papa pahū.No ka laʻana, ua wehewehe ʻia ka pae pahū o Exd II BT4 ma lalo nei.
Ex: hōʻailona pahū
d: ʻO ke ʻano pahū-hōʻoia he ʻano lapalapa.Aia nā ʻano IA a me IB i loko o ka palekana;Hoʻonui i ka ʻano palekana E;Aila piha o;Hoʻopiha ʻia ke one Q;ʻO ka ninini a me ka hoʻopaʻa ʻana i ke ʻano m;ʻAno hui (no ka laʻana, hoʻohana pinepine ʻia ka hui ʻana no ka pahu hāʻawi pahū).
II: E pili ana i ka Papa II mea pahū-pale uila.He kūpono kēia ʻano mea pahū pahū no nā wahi kinoea pahū ʻē aʻe koe wale nā mine lanahu.(ʻO nā mine lanahu ka Papa I).Aia pū kekahi papa III: nā lako uila no nā lewa lepo pahū koe wale nā mine lanahu.Papa IIIA: nā lele lele puhi ahi;Papa IIIB: ka lepo non-conductive;Papa IIIC: lepo conductive.
B: Papa IIB kinoea.Aia kekahi mau māka IIC a me IIA.ʻO ka papa IIC ka pae kiʻekiʻe loa a hiki ke hoʻohana ʻia i IIA a me IIB.Hiki ke hoʻohana i ka Level IIB i ka Level IIA.Akā ʻaʻole hiki i ka pae haʻahaʻa ke pili i ka pae kiʻekiʻe.
T4: ʻO ka pūʻulu wela ʻo T4, a ʻo ka nui o ka wela o ka ʻili o nā mea hana ma lalo o 135°C.
