1. No ke aha e koho ai i ka Projection kūpono / MFDC Welder mea nui
Ma ka hana ʻana o kēia wā, ʻo ka maikaʻi o ka wiliwili, ka pono hana, ka hoʻohana ʻana i ka ikehu, a me ka -paʻa lōʻihi e hilinaʻi nui i ke koho ʻana i ka mīkini wiliwili kūpono. No nā mea e like me ke kila -ikaika kiʻekiʻe, ke kila kuhiliʻole, ka pepa uʻi, a me ka aluminika, ʻokoʻa ka hana wiliwili ma muli o ke ʻano o nā mea hana wili i hoʻohana ʻia.
ʻO ke koho ʻana i ka mīkini hewa hiki ke hopena i nā welds nāwaliwali, kiʻekiʻe o ka hana hou ʻana, ʻoi aku ka nui o nā kumukūʻai ikehu, a me nā hemahema pinepine. No laila, pono ka loiloi ʻana i nā mea waiwai, ka nui o ka hana, ka mana lako, a me nā pono scaling e hiki mai ana ma mua o ke kūʻai ʻana.
2. Nā ʻano maʻamau o nā mea welder kiko a me ka projection
| ʻAno | Nā hiʻohiʻona | ʻO nā hihia hoʻohana maikaʻi loa | |
| 1 | ʻO ka welder wahi kūʻē AC | Kuʻo AC kuʻuna | ʻO ke kumu kūʻai mua haʻahaʻa akā kiʻekiʻe ka hoʻohana ʻana i ka ikehu a me ka hoʻokomo wela paʻa ʻole. ʻAʻole kūpono no ka hana kiʻekiʻe-pololei a i ʻole he nui-mea hana. |
| 2 | Hoʻokuʻu ʻia ka Capacitor (CD) Welder | ʻO ka wiliwili hoʻokuʻu koke | Nui no nā pā pākaukau, nā ʻāpana liʻiliʻi, nā lau lahilahi. ʻAʻole kūpono no nā mea ʻoi aku ka mānoanoa a i ʻole nā ʻāpana kūkulu ikaika kiʻekiʻe. |
| 3 | MFDC (Medium-Frequency Direct Current) Spot / Projection Welder | Hoʻololi i ka AC → DC → kiʻekiʻe -frequency (800–2000 Hz) → DC pukana |
ʻO ka hana holoʻokoʻa maikaʻi loa no ka wikiwiki, ka ikaika o ka ikehu, ka paʻa, a me ka hoʻoheheʻe ʻana i nā mea he nui. He kūpono kūpono no ka hana ʻoihana nui. |
MFDC welderse hoemi i ke au wiliwili e25–35%hoʻohālikelike ʻia me nā welders AC, haʻahaʻa i ka hoʻohana ʻana i ka ikehu, a hoʻonui nui i ke ola electrode.
3. Nā mea nui i ke koho ʻana i kahi Projection a i ʻole MFDC Welding Machine
He kūpono nā welders MFDC no:
- 1. Ke kila ikaika -kiʻekiʻe
- 2. Ke kila kila
- 3. Ke kila kila
- 4. Aluminum a me nā mea conductive ʻē aʻe
- 5. ʻAha -nui a me ka like ʻole-metala wiliwili
No nā hui e pili ana i nā modula pākaukau EV, nā ʻāpana mea hana, nā ʻāpana kaʻa, a i ʻole nā mea metala pololei, ʻo ka welding MFDC e hōʻoia i ka maikaʻi o ka weld paʻa.
ʻO kahi pōmaikaʻi nui o ka ʻenehana MFDC ʻo ia ka wikiwiki wili a me ka pololei o ka mana:
- 0.25 ms hoʻonā mana o kēia manawa
- ʻOi aku ka wikiwiki o ka pane 80x ma mua o nā welders AC kuʻuna
- Pōkole wiliwili pōʻaiapuni
- ʻOi aku ka paʻa o ka wiliwili
- Hoʻokomo wela paʻa
He mea kūpono kēia i nā welders MFDC no ka -nui kiʻekiʻe a me nā laina hana ʻakomi.
ʻO nā mea welder MFDC e hōʻemi nui ana i ka ikehu - lōʻihi a me nā koina mālama.
- 1. 30–40% haʻahaʻa ka hoʻohana ikehu a me nā mīkini AC
- 2. Ka helu mana a hiki i 0.95+
- 3. Hoʻemi ʻia ka lole electrode (hiki i ka 50% lōʻihi ke ola)
- 4. E emi iho ka wela a me ka hoʻohana ʻana i ka ikehu (hiki i ka 92% ka maikaʻi)
No nā mea hana, hoʻohaʻahaʻa loa kēia mau waihona i nā bila mana makahiki a me nā lilo mālama.
Hoʻopuka nā mea welders MFDC i ka hopena DC paʻa, hoʻemi ʻia:
- ʻōpuʻu
- Hoʻololi ʻana o ka mea hana
- Nā ʻāpana i hoʻopilikia ʻia i ka wela-.
- Pili ka uila
No nā noi e koi ana i ka hiʻona kiʻekiʻe a me nā hui hoʻolālā ikaika -e like me nā ʻāpana kino kaʻa, nā ʻāpana EV, a me nā hale hao kuhili ʻole-e hāʻawi i nā hopena kūlike.
Ma mua o ke koho ʻana i kahi mīkini, e noʻonoʻo:
- 1. Loaʻa omana 3-phase(e laʻa, 380V / 50Hz)
- 2. ʻOi aku ka nui o ka wai ma mua a i ʻole like me nā kikoʻī i makemake ʻia.
- 3. Wahi no ka hoʻokomo a me ka mālama
- 4. ʻO ka ventila kūpono no ka mea transformer a me ka mea hoʻoponopono
Pono ka ʻenehana hoʻoheheʻe projection i ka ʻike ʻenehana ikaika-pehea. E koho i kahi mea hoʻolako e hāʻawi:
- Nā ho'āʻo wiliwili ʻoihana
- Alakaʻi kaʻina hana hilinaʻi
- Hoʻomaʻamaʻa piha a ma hope o -lawelawe kūʻai
- Loaʻa nā ʻāpana ʻāpana
- Kākoʻo automate a hoʻohui
He mea koʻikoʻi kēia mau lawelawe no ka -hana paʻa lōʻihi.
4. Kākoʻo ʻia ʻo MFDC e nā ʻikepili
Eia kekahi mau hōʻailona hana i ʻōlelo pinepine ʻia ma ka ʻoihana:
- Ua hoʻomaikaʻi ʻia ka ikaika o ka ikehu mai 60% (AC) iʻOi aku a i ʻole like me 92%
- 30–40%emi iho ka uila
- 0.25 mspololei hoʻoponopono o kēia manawa
- 50% hoemii ka lole electrode
- ʻOi aku ke kiʻekiʻe o ka hoʻoheheʻe ʻana i ka wili no ka aluminika, ke kila kila, a me nā pepa galvanized
- ʻOi aku ka ikaika a ʻoi aku ka paʻa o ka weld nuggets
Hōʻike kēia mau helu ʻikepili i ke ʻano o nā welders MFDC ma mua o nā mīkini kuʻuna ma kahi kokoke i kēlā me kēia noi ʻoihana.
5. Ka papa inoa koho ma'amau
No ka hōʻoia ʻana e koho ʻoe i ka welder projection kūpono:
✓ E hoʻomaopopo i kāu pono hana
- ʻAno a me ka mānoanoa
- Ka nui puka i manaʻo ʻia
- ʻAno hui wiliwili (kahi-kahi, ʻāpana-nui, metala like ʻole)
✓ Noi i nā ho'āʻo wiliwili mea maoli
- E hoʻāʻo mau me kāu mau mea maoli a me ka mānoanoa ma mua o ka hoʻopau ʻana i ke kūʻai.
✓ E nānā i ka mākaukau o ka hale
- Hāʻawi mana (3-phase)
- Koi hooluolu
- Wahi a me ka hoʻonohonoho palekana
✓ E loiloi i ka huina kālā o ka ʻona (TCO)
- ʻOi aku ke kumukūʻai o nā mīkini MFDC, akā ʻo ka mālama ʻana i ka ikehu a me ka mālama haʻahaʻa e hoʻihoʻi pinepine i ke kumukūʻai i loko1–2 makahiki.
✓ E koho i kahi mea hana pono
- Makemake i nā mea hoʻolako me nā mana ʻenekinia ikaika, ka ʻike hana, a me ka ʻike lawelawe.
✓ Hoʻolālā no ka automation
- Inā manaʻo ʻia ka hoʻohui ʻana o ka robot i ka wā e hiki mai ana, e koho i kahi welder me ka mana kikohoʻe, ka nānā ʻana, a me nā pilina kamaʻilio ʻoihana.
Ka Hopena: ʻO MFDC Projection Welders ke kūlana o kēia manawa
Ke neʻe nei ka hana ʻana i ka maikaʻi kiʻekiʻe, ka hoʻohana haʻahaʻa i ka ikehu, ka mana nui-material, a me ka automation, paʻakikī ka poʻe welder AC kuʻuna e hoʻomau.MFDC projection welding machineshāʻawi i nā mea maikaʻi ma ka wikiwiki, ka paʻa, ka maikaʻi o ka weld, a me ka mālama ʻana - lōʻihi.
No nā hui e ʻimi nei i ka ʻoi aku ka maikaʻi, ke kumu kūʻai haʻahaʻa, a me nā ʻōnaehana hana mākaukau e hiki mai ana, ʻo ke koho ʻana i ka welder projection MFDC kūpono he waiwai hoʻolālā e hōʻoia i ka hoʻokūkū ikaika a me nā pōmaikaʻi lōʻihi -
