Pehea e koho ai i ka ʻoki kinoea no ka mīkini ʻoki plasma?

Nā mīkini ʻoki plasmaʻoi aku ke kiʻekiʻe o ka volta kaumaha ʻole a me ka volta hana, a ʻo ka piʻi ʻana o ka volta ʻo ia ka piʻi ʻana o ka arc enthalpy.ʻOiai e hoʻonui ana i ka enthalpy, e hōʻemi ana i ke anawaena jet a me ka hoʻonui ʻana i ke kahe o ke kinoea hiki ke hoʻomaikaʻi i ka wikiwiki o ka ʻoki a me ka maikaʻi o ka ʻoki.Pono nā voltage kiʻekiʻe ke hoʻohana i nā kinoea me nā ikehu ionization kiʻekiʻe, e like me ka nitrogen, hydrogen a i ʻole ea.He aha nā ʻōlelo aʻoaʻo koho kinoea like ʻole a me nā helu?E nānā i ka kikoʻī kikoʻī o ke kinoea e nā mea hana mīkini ʻoki plasma ʻoihana.

Hoʻohana maʻamau ʻia ka hydrogen ma ke ʻano he kinoea kōkua i hui pū ʻia me nā kinoea ʻē aʻe, a ʻo ke kinoea H35 kekahi o nā kinoea me ka ikaika o ka ʻoki ʻoki arc plasma.Ke hui pū ʻia ka hydrogen me ka argon, ʻo ka hapa nui o ka hydrogen he 35%.No ka mea hiki i ka hydrogen ke hoʻonui nui i ka volta arc, he enthalpy kiʻekiʻe ka hydrogen plasma jet, a ʻoi aku ka maikaʻi o ka ʻoki ʻana o ka jet plasma.

Hiki i ka oxygen ke hoʻonui i ka wikiwiki o ka ʻoki ʻana i nā mea kila māmā.I ka ʻoki ʻana me ka oxygen, ua like loa ke ʻano o ka ʻoki ʻana me ka mīkini ʻoki ahi CNC.ʻO ka arc plasma kiʻekiʻe a me ka ikaika kiʻekiʻe e hoʻolōʻihi i ka wikiwiki o ka ʻoki ʻana, akā pono e hoʻohana pū ʻia me nā electrodes oxidation-resistant kiʻekiʻe.Hoʻonui i ke ola o nā electrodes.

ʻO ka slag i hana ʻia e ka ʻoki ʻana i ka ea a me ka ʻoki ʻana o ka nitrogen ua like ia, no ka mea, ʻo ka nui o ka nui o ka nitrogen i ka lewa ma kahi o 78%, a aia ma kahi o 21% oxygen i ka lewa, no laila ʻoi aku ka wikiwiki o ka ʻoki ʻana i ke kila kalapona haʻahaʻa me ka ea. kiʻekiʻe, a ʻo Air ke kinoea hana ʻoi aku ka maikaʻi, akā ʻo ka ʻoki ʻana me ka ea wale nō e hoʻopilikia i nā pilikia e like me ke kau ʻana o ka slag, kerf oxidation, a me ka hoʻonui ʻana o ka nitrogen.ʻO ke ola haʻahaʻa o nā electrodes a me nā nozzles e pili pū i ka hana pono a me ka ʻoki ʻana i nā kumukūʻai.

Ma lalo o ke kūlana o ka mana mana kiʻekiʻe, ʻoi aku ka maikaʻi o ka arc plasma nitrogen a ʻoi aku ka ikaika o ka jet ma mua o ka argon.No ka laʻana, i ka wā e ʻoki ai i ke kila kila a me ka nickel-based alloys, he liʻiliʻi loa ka slag ma ka ʻaoʻao haʻahaʻa, a hiki ke hoʻohana wale ʻia ka nitrogen.Hiki ke hui pū me nā kinoea ʻē aʻe.Hoʻohana pinepine ʻia ka Nitrogen a i ʻole ea e like me ke kinoea hana i ka ʻoki ʻoki ʻana, a ua lilo kēia mau kinoea ʻelua i ke kinoea maʻamau no ka ʻoki kiʻekiʻe o ke kila kalapona.

Paʻa ka hana o ka argon, ʻaʻole ia e pane me kekahi metala a hiki i ka wela kiʻekiʻe, a ʻo ka nozzle a me ka electrode i hoʻohana ʻia he ola lōʻihi.Eia naʻe, haʻahaʻa ka volta o ka argon plasma arc, ʻaʻole kiʻekiʻe ka enthalpy, a ua kaupalena ʻia ka hiki ke ʻoki.Ke hoʻohālikelike ʻia me ka ʻoki ʻana i ka ea, e hoʻemi ʻia ka mānoanoa o ka ʻoki ʻana ma kahi o 25%.Eia kekahi, ʻoi aku ka kiʻekiʻe o ka ʻili o ka metala i hoʻoheheʻe ʻia, ma kahi o 30% ʻoi aku ka kiʻekiʻe ma mua o ke kaiapuni nitrogen, no laila e nui aʻe nā pilikia e kau ana i ka slag.ʻO ka ʻoki ʻana me ke kinoea hui ʻia o nā kinoea ʻē aʻe e pili ana i ka slag.No laila, ʻaʻole hoʻohana wale ʻia ka argon maʻemaʻe no ka ʻoki plasma.

MEN-LUCK, he mea hana oihana omea ʻoki laser, hoʻolako i nā ʻano mīkini ʻoki laser precision a pau, nā mīkini welding laser, a me nā mīkini hoʻomaʻemaʻe laser i loko o ka waihona no ka manawa lōʻihi, a hāʻawi i nā lawelawe hōʻoia i ka manawa like.Inā loaʻa iā ʻoe kekahi mea e pono ai ka ʻoki ʻoki laser, e ʻoluʻolu e hoʻokaʻaʻike mai iā mākou!
