Tataiso ea Mohato o le Mong ea ho Khetha Mofuta o Nepahetseng
Khetha ho latela litekanyo tse hlano: boholo ba mosebetsi, thepa, sebaka sa ho thatafala, litlhoko tsa ho nepahala, le maemo a ts'ebeliso. Ha ho hlokahale hore u tšoenyehe, latela tataiso feela 'me u ka etsa qeto.
I. Sa pele, arola ka mefuta e meraro e meholo ea liteko tsa ho thatafala
1. Rockwell Hardness Tester (HRC/HRB/HRA)
E loketse: tšepe e timisitsoeng, tšepe e chesitsoeng, li-bearing, lisebelisoa, likarolo tse phekoloang ka mocheso
Melemo: ho nepahala ho hoholo, ho sebelisoa haholo maemong a naha, lisebelisoa tse tloaelehileng bakeng sa tlhahlobo ea boleng ba fektheri
Mathata: o tlameha ho nka disampole / mofuta wa komporo, dikarolo tse kgolo di ke ke tsa sisinyeha kapa tsa lekoa sebakeng seo
Seo u lokelang ho se lekanya:
HRC: tšepe e thata e timmeng (li-dies, lisebelisoa, li-gear)
HRB: koporo, aluminium, tšepe e nang le khabone e tlase, tšepe e bonolo
2. Setei sa ho Lekanya Bohloko ba Brinell (HB)
E loketse bakeng sa: tšepe e entsoeng ka tšepe, tšepe e entsoeng ka tšepe, motsoako oa aluminium, motsoako oa koporo, likarolo tse entsoeng ka tšepe e thata
Melemo: ho kenella ho hoholo, ho nepahetseng haholo bakeng sa thepa e nang le mahoashe le e sa lekanang
Mathata: ho kobeha ho hoholo, ho senya, bokgoni bo tlase, ho loketse ho hlahlojoa ha libaka tsa laboratori
3. Leeb Hardness Tester (e nkehang habobebe ho HL ho ea ho HRC/HB/HV)—YY251D Leeb Hardness Tester
E loketse: likarolo tse kholo, liteko tsa sebakeng seo, likarolo tse ke keng tsa qhaqhoa, hlobo e boima, meqolo, li-shaft
Melemo: e ka tšoaroa ka letsoho ebile e nkeha habonolo, ha e senye, ha ho hlokahale hore ho nkuoe disampole, e ka sebelisoa maemong a otlolohileng, a bataletseng, kapa a holimo
Mathata: ho nepahala ho tlase hanyane ho feta komporo ea Rockwell, liphoso tse kholo bakeng sa likarolo tse tšesaane le tse nyane
II. Khetha ho latela maemo a ts'ebeliso (a sebetsang haholo)
Boemo ba 1: laboratori ea workshop, tlhahlobo ea boleng ba thepa e kenang / kalafo ea mocheso, ho hlokahala ho nepahala ho phahameng. Khetha sesebelisoa sa ho leka ho thatafala ha Rockwell sa komporo.
E kgethwa bakeng sa di-hardware tse akaretsang, difeme tsa ho etsa di-die le tsa kalafo ya mocheso.
Boemo ba 2: tšepe e entsoeng ka tšepe, lintho tse entsoeng ka tšepe, motsoako oa aluminium, likarolo tse entsoeng ka tšepe e sa lokisoang
Khetha sesebelisoa sa ho leka bothata ba Brinell
Boemo ba 3: likarolo tse kholo tse ke keng tsa sisinyeha, liteko tsa sebakeng seo, liforomo / meqolo / li-shaft tse kholo U tlameha ho khetha sesebelisoa sa ho leka ho thatafala ha Leeb se nkehang habobebe
Boemo ba 4: likarolo tse nyane, maqephe a masesaane, bothata ba bokaholimo ba likarolo tse nang le khabone le tse nang le nitride Khetha sesebelisoa sa ho lekola bothata ba Vickers (HV)
E loketse: maqephe a masesaane, mathoko a lisebelisoa, masela a koahetsoeng, le mealo e thatafetseng.
III. Khetha ho latela botenya/boholo ba karolo ea mosebetsi
Likarolo tse kholo, tse boima, le tse sa sisinyeheng → Leeb
Disampole tse tloaelehileng, dikarolo tse nyane, di ka bewa komporong → Rockwell
Likarolo tse tšesaane < 3mm, tse tiileng holim'a metsi → Vickers
Likheo tse se nang letho, thepa e sa tšoaneng → Brinell
IV. Khetha ho latela boemo ba thatafalo
Lisebelisoa tse bonolo: aluminium, koporo, tšepe e nang le khabone e tlase → HRB / HB
Boima bo mahareng: tšepe e timmeng le e halefileng, tšepe ea sebopeho → HRC / HB
Ho thatafala ho hoholo: di-dies tse timilweng, disebediswa, di-bearing → HRC / HV
Mealo e mesesaane haholo ea bokaholimo / mealo e nang le carburized → HV Vickers
