No ke aha e hoʻonui ai ka mīkini mīkini haʻahaʻa haʻahaʻa me ka hana degassing hoʻohui i nā pono o nā elastomers PU haʻahaʻa haʻahaʻa.
ʻOki ʻia ka mea hana i hana ʻia me nā mea conductive e ka hoʻohana ʻana i ka jet plasma thermal wikiwiki.
Inā ʻoe e hana ana i ka hana kiʻi a i ʻole ka hana ʻana i nā huahana i hoʻopau ʻia, hāʻawi ka ʻoki plasma i nā mea hiki ʻole ke ʻoki i ka alumini a me ke kila kila. Akā he aha ka mea ma hope o kēia ʻenehana hou? nā mīkini ʻoki a me ka ʻoki plasma.
ʻO ka ʻoki ʻana i ka plasma kahi hana o ka ʻoki ʻana i nā mea conductive me nā jet accelerated o ka plasma thermal. ʻO nā mea maʻamau e hiki ke ʻoki ʻia me ka lama plasma he kila, ke kila kila, aluminika, keleawe, keleawe, a me nā metala conductive ʻē aʻe. , ka mālama kaʻa a me ka hoʻoponopono ʻana, ka hana ʻoihana, ka hoʻopakele a me ka scrapping. .Plasma cutting-Conductive gas me kahi mahana a hiki i 30,000 ° C hana i ka ʻokiʻoki plasma i mea kūikawā.
ʻO ke kaʻina hana maʻamau o ka ʻoki ʻana i ka plasma a me ka hoʻoheheʻe ʻana ʻo ia ka hana ʻana i kahi ala uila no ke kinoea ionized overheated (ʻo ia hoʻi ka plasma), mai ka mīkini ʻoki plasma ponoʻī ma o ka mea hana e ʻoki ʻia, a laila e hana i kahi kaapuni piha e hoʻi i ka mīkini ʻoki plasma ma o ka kahua ʻāina.Hoʻokō ʻia kēia ma ka puhi ʻana i ke kinoea i hoʻopaʻa ʻia (oxygen, ea, inert gas a me nā kinoea ʻē aʻe, e pili ana i ka mea e ʻoki ʻia) ma o ka nozzle kikoʻī i ka wikiwiki kiʻekiʻe i ka mea hana. ka nozzle kinoea a me ka mea hana pono'ī. Hoʻopili kēia arc i kahi hapa o ke kinoea a hana i kahi channel plasma conductive. I ka wā e kahe ai ke au mai ka ʻoki ʻoki plasma i loko o ka plasma, e hoʻokuʻu i ka wela e hoʻoheheʻe i ka mea hana. I ka manawa like, ka hapa nui. ʻO ka plasma kiʻekiʻe a me ke kinoea i hoʻopaʻa ʻia e puhi i ka metala hoʻoheheʻe wela, e hoʻokaʻawale i ka mea hana.
ʻO kaʻokiʻokiʻana i ka plasma he ala kūpono no kaʻokiʻana i nā mea lahilahi a me ka mānoanoa. Hiki i nā lama paʻa lima keʻoki i nā papa kila mānoanoa 38 mm, aʻoi aku ka ikaika o nā lama i hoʻomaluʻia e ka lolouila hiki keʻoki i nā papa kila mānoanoa 150 mm. "cones" kūloko no ka ʻoki ʻana, he mea pono loa ia no ka ʻoki ʻana a me ka hoʻopaʻa ʻana i nā ʻāpana curved a i ʻole nā kihi.
Hoʻohana pinepine ʻia nā mīkini ʻokiʻoki plasma manual no ka hoʻoili ʻana i nā metala lahilahi, ka mālama ʻana i ka hale hana, ka mālama ʻana i ka mahiʻai, nā kikowaena hoʻoponopono welding, nā kikowaena lawelawe metala (scrap, welding a me ka wehe ʻana), nā hana kūkulu (e like me nā hale a me nā alahaka), ka hana moku kalepa, hana trailer, kaʻa. hoʻoponopono A me nā hana noʻeau (hana a me ka welding).
ʻOi aku ka nui o nā mīkini ʻoki plasma mīkini ma mua o nā mīkini ʻoki plasma manual a hoʻohana ʻia me ka ʻoki ʻana i nā papa. papaʻaina a me ka puka puka i hoʻohana ʻia. ʻAʻole maʻalahi kēia mau ʻōnaehana, no laila pono e noʻonoʻo ʻia kā lākou mau mea āpau a me ka hoʻonohonoho ʻōnaehana ma mua o ke kau ʻana.
I ka manawa like, hoʻolako pū ka mea hana i kahi hui hui kūpono no ka ʻokiʻoki plasma a me ka welding.
Ua puka mai ka ʻoki ʻana i ka plasma mai ka welding plasma i nā makahiki 1960 a ua hoʻomohala ʻia i kahi kaʻina hana maikaʻi loa no ka ʻoki ʻana i ka metala a me nā papa i nā makahiki 1980. Ke hoʻohālikelike ʻia me ka ʻokiʻoki "metal-to-metal" maʻamau, ʻaʻole hana ka ʻokiʻoki plasma i nā shavings metala a hāʻawi i ka ʻoki pololei. ʻO nā mīkini ʻoki plasma mua he nui, lohi a pipiʻi. i nā makahiki 1990. Mahalo i ka ʻenehana CNC, ua loaʻa i ka mīkini ʻoki plasma ka maʻalahi i ka ʻoki ʻana i nā ʻano like ʻole e like me ke ʻano o nā kuhikuhi like ʻole i hoʻolālā ʻia i ka ʻōnaehana CNC o ka mīkini. nā pā kila pālahalaha me ʻelua mau koi ʻoni wale.
I nā makahiki he ʻumi i hala iho nei, ua hoʻomohala nā mea hana o nā mīkini ʻoki plasma like ʻole i nā hiʻohiʻona hou me nā nozzles liʻiliʻi a me nā arcs plasma thinner. ʻO kēia ka mea e hiki ai i ka ʻoki ʻoki plasma ke loaʻa i ka laser-like precision. nā ʻāpana e koi liʻiliʻi a ʻaʻohe hana hou, e hoʻomaʻamaʻa i nā kaʻina hana ʻē aʻe e like me ka welding.
Hoʻohana ʻia ka huaʻōlelo "ka hoʻokaʻawale wela" ma ke ʻano he huaʻōlelo maʻamau no ke kaʻina hana o ka ʻoki ʻana a i ʻole ka hana ʻana i nā mea e ka hana o ka wela.I keʻano o kaʻokiʻana a iʻole kaʻokiʻana i ke kahe o ka oxygen,ʻaʻohe mea e pono ai no ka hana houʻana i ka hana houʻana.ʻO nā hana nuiʻekolu he oxy-fuel, plasma a me ka laser cutting.
Ke hoʻoheheʻe ʻia ka hydrocarbons, hana lākou i ka wela. E like me nā kaʻina puhi ahi ʻē aʻe, ʻaʻole pono ka ʻoki ʻana i ka oxy-fuel i nā lako makamae, maʻalahi ka lawe ʻana i ka ikehu, a ʻo ka hapa nui o nā kaʻina hana ʻaʻole pono i ka uila a me ka wai hoʻomaha. ʻO ka ʻoki wahie oxygen ke kaʻina hana nui no ka ʻoki ʻana i ke kila kaumaha, ke kila non-alloy a me ke kila haʻahaʻa, a hoʻohana ʻia hoʻi e hoʻomākaukau i nā mea no ka welding ma hope. ʻO ka wikiwiki o ka wela wela e pili ana i ke kinoea. ʻO ka wikiwiki o ka ʻoki pono ʻana e pili ana i ka maʻemaʻe o ka oxygen a me ka wikiwiki o ka oxygen injection. High clean clean oxygen, optimized nozzle design and correct fuel gas ensure huahana kiʻekiʻe a hoʻemi i ke kumukūʻai kaʻina holoʻokoʻa.
Ua hoʻomohala ʻia ka ʻoki plasma i ka makahiki 1950 no ka ʻoki ʻana i nā metala ʻaʻole hiki ke puhi ʻia (e like me ke kila kila, aluminika, a me ke keleawe). Hiki i ke kahawai plasma wela ke oki i na mea e like me ka plastics (no transfer arc). Hiki ke hoʻokō ʻia ka pilina hou o ke ala hoʻokuʻu ʻia e ke kinoea kōkua (ke kinoea pale). ʻO ke koho ʻana i ka hui plasma kūpono / pale kinoea hiki ke hoʻemi nui i ke kumukūʻai kaʻina holoʻokoʻa.
ʻO ka ʻōnaehana Autorex o ESAB ka hana mua e hoʻokaʻawale i ka ʻoki plasma. Hiki ke hoʻohui maʻalahi i nā laina hana e kū nei. (Source: ESAB Cutting System)
ʻO ka ʻoki ʻana i ka laser ka ʻenehana ʻoki wela hou loa, i hoʻomohala ʻia ma hope o ka ʻoki ʻana i ka plasma. Hoʻokumu ʻia ka kukuna laser i loko o ka lua resonant o ka ʻōnaehana ʻoki laser. ʻO ka mea pale kinoea e komo i ka lua resonant mai ka cylinder a hoʻonui i ka hana ʻoki. , particles and vapors. ʻOi loa no nā ʻōnaehana hana kiʻekiʻe (> 4kW), ua paipai ʻia ka nitrogen wai. I ka ʻoki ʻana i ka laser, hiki ke hoʻohana ʻia ka oxygen a i ʻole nitrogen e like me ke ʻoki kinoea. e like me ka oxy-fuel cutting.Maʻaneʻi, he mea nui ka maʻemaʻe o ka oxygen. Hoʻohanaʻia ka Nitrogen i ke kila kila, aluminika, a me ka nickel alloys no ka loaʻaʻana o nāʻaoʻao maʻemaʻe a mālama i nā waiwai kī o ka substrate.
Hoʻohana ʻia ka wai ma ke ʻano he mea hoʻomaha i nā kaʻina hana ʻoihana e lawe mai i nā mahana kiʻekiʻe i ke kaʻina. ʻO ia ka mea e pili ana i ka wai i ka ʻoki ʻana i ka plasma. ʻO ke kinoea, he plasma arc ka mea maʻamau i hanaʻia,ʻo ia ka hihia me ka nui o nā mīkiniʻokiʻoki plasma. Ke hoʻokomoʻia ka wai i loko o ka plasma arc, e hoʻoulu ai ke kiʻekiʻe. Inā hoʻohālikelike ʻia nā mea maikaʻi o ke kaʻina hana i luna me ka plasma kuʻuna, hiki ke ʻike ʻia ua hoʻomaikaʻi maikaʻi ʻia ka maikaʻi o ka ʻoki ʻana a me ka rectangularity o ka ʻokiʻoki, a ua mākaukau maikaʻi nā mea welding. hiki ke ʻike ʻia ka ʻoki ʻana, ka piʻi ʻana o ka wikiwiki o ka ʻoki ʻana, ka emi ʻana o ka curvature pālua, a me ka emi ʻana o ka nozzle erosion.
Hoʻohana pinepine ʻia ke kinoea Vortex i ka ʻoihana ʻokiʻoki plasma e hoʻokō ʻoi aku ka maikaʻi o ka hoʻopaʻa ʻana i ke kolamu plasma a me ka ʻāʻī paʻa paʻa. ʻO kaʻokoʻa ma waena o ka palena kiʻekiʻe a me ka liʻiliʻi e piʻi aʻe me ka helu o nā vortices. ʻO ka ʻokoʻa ʻokoʻa nui ma ka ʻaoʻao radial e hōʻemi i ke arc a hoʻoulu i ka nui o kēia manawa a me ka wela ohmic kokoke i ke kumu.
Ke alakaʻi nei kēia i kahi wela kiʻekiʻe ma kahi kokoke i ka cathode. Pono e hoʻomaopopo ʻia aia ʻelua mau kumu e hoʻolōʻihi ai ke kinoea wili i ka corrosion o ka cathode: hoʻonui i ke kaomi i loko o ke keʻena kaomi a hoʻololi i ke ʻano kahe kokoke i ka cathode. e noʻonoʻo ʻia, e like me ka mālama ʻana i ka momentum angular, e hoʻonui ke kinoea me ka helu vortex kiʻekiʻe i ka ʻāpana velocity vortex ma ke kihi ʻoki. ʻokoʻa.
E hāʻawi mai iā mākou i ka manaʻo no kēia ʻatikala. He aha nā pilikia i pane ʻole ʻia, a he aha kāu makemake? E kōkua kou manaʻo iā mākou e lilo i mea maikaʻi!
