Khethollo ea Mekhoa ea ho Pholisa bakeng sa Mechini ea Welding ea Maqhubu a Mahare a Hare a Tsoang Pele

Mechini ea ho tjheseletsa sebakeng sa Medium-frequency direct current (MFDC) e sebelisoa haholo liindastering tse fapaneng bakeng sa ho nepahala le ho sebetsa hantle ha ho kopanya litšepe. Ho etsa bonnete ba hore mechini ena e phela nako e telele le ho sebetsa hantle, ho bohlokoa hore ho be le sistimi e sebetsang ea ho pholisa. Sengoliloeng sena se tla fana ka kakaretso ea likarolo tsa litsamaiso tse pholisang bakeng sa mechini ea tjheseletsa ea letheba ea MFDC.

I. Sistimi ea ho Pholisa Moea

Sistimi ea ho pholisa moea ke mofuta o atileng haholo o sebelisoang bakeng sa mechini ea tjheseletsa ea letheba ea MFDC. E kenyelletsa tšebeliso ea li-fan ho qhala mocheso o hlahisoang nakong ea ts'ebetso ea welding. Karohano ka har'a sistimi ena e ka aroloa hape ka mekhahlelo e 'meli:

1. Ho Pholisa Moea ka Matla:
   • Ka mokhoa ona, ho sebelisoa lifene tse matla ho butsoela moea o pholileng holim’a likaroloana tsa mochine, ho akarelletsa le li-transformer, li-diode le likhoele.
   • Sistimi ena ha e na litšenyehelo ebile e bonolo ho e hlokomela.
2. Pholiso ea Moea oa Tlhaho:
   • Pholiso ea moea ea tlhaho e itšetlehile ka moralo oa mochini ho lumella moea o potolohileng ho potoloha likarolo tsa ona.
   • Le hoja e sebetsa hantle, e ka 'na ea se ke ea tšoanela mechine e nang le mocheso o phahameng oa mocheso.

II. Mokhoa oa ho futhumatsa metsi

Lisebelisoa tsa ho futhumatsa metsi li sebelisoa ha mocheso o hlahisoang ke mechini ea ho tjheseletsa libaka tsa MFDC o phahame ka mokhoa o ikhethang. Sistimi ena e ka aroloa ka mefuta e latelang:

1. Ho Pholisa Metsi a Koetsoeng:
   • Ka mokhoa ona, mokhoa o koetsoeng o potoloha metsi ka mochine oa mocheso, o senyang mocheso ka katleho.
   • Litsamaiso tse koetsoeng li sebetsa hantle ho boloka mocheso o tsitsitseng.
2. Ho Pholisa Metsi a Open-Loop:
   • Litsamaiso tse bulehileng-loop li sebelisa phallo e tsoelang pele ea metsi ho tlosa mocheso mochining.
   • Le ha li sebetsa hantle, li ka sebetsa hantle ho feta lits'ebetso tse koetsoeng.

III. Hybrid Cooling System

Mechini e meng ea li-welding ea MFDC e kopanya lisebelisoa tsa ho futhumatsa moea le metsi ho ntlafatsa ts'ebetso. Sistimi ena e nyalisitsoeng e lumella taolo e betere ea mocheso, haholo mechini e nang le litekanyetso tse fapaneng tsa ho hlahisa mocheso.

IV. Oli Cooling System

Lisebelisoa tsa ho pholisa oli ha li tloaelehe haholo empa li fana ka bokhoni bo botle ba ho felisa mocheso. Li arotsoe ka:

1. Ho qoelisoa ho pholile:
   • Ka ho qoelisoa ka ho qoelisoa, likarolo tsa mochine li qoelisoa ka oli ea dielectric.
   • Mokhoa ona o sebetsa hantle ka ho lahla mocheso 'me o fana ka insulation e eketsehileng.
2. Ho Pholisa Oli ka ho Otloloha:
   • Ho pholisa oli ka kotloloho ho kenyelletsa ho tsamaisoa ha oli ka likanale kapa lijase ho potoloha likarolo tsa bohlokoa.
   • Mokhoa ona o loketse mechini e nang le litaba tsa ho futhumatsa sebakeng.

Khetho ea sistimi ea ho pholisa mochini oa welding oa MFDC e ipapisitse le lintlha tse kang moralo oa mochini, tlhahiso ea mocheso, le lintlha tsa litšenyehelo. Ho utloisisa karohano ea litsamaiso tsena tsa ho pholisa ho bohlokoa bakeng sa ho netefatsa ts'ebetso e nepahetseng le bophelo bo bolelele ba lisebelisoa tsena tsa bohlokoa tsa indasteri. Ho khetha sistimi e nepahetseng ea ho futhumatsa ho ka ntlafatsa boleng ba welding, ho fokotsa litšenyehelo tsa tlhokomelo, le ho lelefatsa bophelo ba mochini.
