Lisebelisoa tsa ho tima
Lisebelisoa tsa ho tima
Lisebelisoa tsa ho tima Haholo-holo e arotsoe ka sebōpi sa motlakase o tima (maqhubu a maqhubu a maqhubu a mahareng), sebōpi se phahameng sa ho tima (sesebelisoa se phahameng sa ho tima), sesebelisoa sa mochini oa ho tima oa CNC le sesebelisoa se kopaneng sa ho tima. Lisebelisoa tsa ho tima li entsoe ka likarolo tse tharo: sesebelisoa sa ho tima mochini, phepelo ea motlakase o mahareng le o phahameng, le sesebelisoa sa ho futhumatsa; Sesebelisoa sa mochini o tima se na le bethe, ho laolla le ho laolla mochini, ho ts’oara, ho potoloha mochini, ho tima transformer le potoloho ea tanka ea resonance, sistimi e futhumatsang, ho tima tsamaiso ea mokelikeli oa metsi, Mochini o tima hangata o entsoe ka sistimi ea taolo ea motlakase, mme mochini o tima seteishene se le seng; mochini o tima o na le mefuta e ‘meli ea sebopeho, e emeng le e tshekaletseng. Mosebelisi a ka khetha mochini o tima (quenching) ho latela ts’ebetso ea ho tima. Bakeng sa likarolo tse ikhethileng kapa lits’ebetso tse ikhethileng, ho latela ts’ebetso ea ho futhumatsa Ho hlokahala ho rala le ho etsa lisebelisoa tse khethehileng tsa mochini o thatafatsang.
Ho sebetsa molao-motheo oa lisebelisoa tse tima:
Molao-motheo o sebetsang oa lisebelisoa tsa ho tima ke hore: mosebetsi o behiloe ho inductor, eo hangata e leng tube ea koporo e sekoti e nang le maqhubu a mahareng kapa maqhubu a phahameng a fapanyetsanang hona joale (1000-300000Hz kapa ho feta). Matla a khoheli a fapanyetsanang a hlahisa matla a khelositsoeng a maqhubu a tšoanang ho mosebetsi. Kabo ea hona joale e hlohlellelitsoeng mosebetsing e sa lekana. E matla ka holimo empa kahare e fokola. E haufi le 0 ho ea mantlha. Sebelisa phello ena ea letlalo, bokaholimo ba mosebetsi bo ka futhumala kapele, ‘me mocheso oa bokaholimo o tla nyolohela ho 800-1000ºC nakong ea metsotsoana e seng mekae, ha mocheso oa mantlha o tla nyoloha hanyane.
Litšobotsi tsa lisebelisoa tse tima
1. Ho sebelisa IGBT e le sesebelisoa sa mantlha le inverter e felletseng ea borokho.
2. E entsoe ka sekhahla sa ts’ebetso ea mojaro oa 100%, e ka sebetsa ka ho tsoelang pele.
3. E ka laoloa ka remoutu mme ea hokelloa ho litekanyo tsa mocheso oa infrared ho hlokomela taolo ea mocheso o iketsang, ho ntlafatsa boleng ba ho futhumatsa le ho nolofatsa ts’ebetso ea basebetsi.
4. Kenya mekhoa ea ho futhumatsa joalo ka lelakabe la oxyacetylene, sebopi sa coke, sebopi sa letsoai sa letsoai, sebopi sa khase, sebopi sa oli, jj.
5. Ho latela mokhoa o iketsang oa ho latela maqhubu le taolo e koetsoeng ea selikalikoe ka bongata.
6. Ho boloka motlakase: 30% ea ho boloka matla ho feta mofuta oa li-tube tsa elektroniki, 20% ea ho boloka matla ha o bapisoa le thyristor maqhubu a mahareng.
7. Ts’ebetso e tsitsitseng: ts’ireletso e felletseng mme ha ho na matšoenyeho.
8. Lebelo la ho futhumatsa ka potlako: ha ho na lera la oxide, deformation e nyane.
9. Saese e nyane: boima bo bobebe ebile ho bonolo ho e kenya.
10. Inductor e arotsoe ke transformer bakeng sa polokeho.
11. Ts’ireletso ea tikoloho: ha ho na tšilafalo, lerata le lerōle.
12. Ho ikamahanya le maemo ho matla: E ka futhumatsa mefuta eohle ea mosebetsi.
13. Nako ea mocheso le ea ho futhumatsa e ka laoloa ka nepo, ‘me boleng ba ts’ebetso bo phahame.
Libaka tsa ts’ebeliso ea lisebelisoa tse tima
