Isithando somlilo esitshisa i-vacuum sisithando somlilo esisebenzisa ukufudumeza ngokunyusa ubushushu ukuze sitshise izinto ezishushu. Sinokwahlulwahlulwa sibe ngamaza ombane, amaza aphakathi, amaza aphezulu kunye nezinye iintlobo, kwaye sinokwahlulwa njengodidi oluncinci lwesithando somlilo esitshisa i-vacuum. Isithando somlilo esitshisa i-vacuum yiseti epheleleyo yezixhobo ezisebenzisa umgaqo wokufudumeza ngokunyusa ubushushu obuphakathi ukuya kwiintloko zokusika i-carbide ezinesamente kunye nee-compacts ezahlukeneyo ze-metal powder phantsi kweemeko ze-vacuum okanye zokukhusela. Sisetyenziselwa i-carbide enesamente, i-dysprosium metal, kunye nezinto ze-ceramic. Yenzelwe imveliso yemizi-mveliso.
Ngoko ke, singayisebenzisa njani ngokukhuselekileyo i-vacuum sintering furnace?
1. Umthombo wamanzi opholileyo wombane ohamba rhoqo, umzimba wesithando somoya, kunye nekhoyili yokungenisa - ithangi lamanzi kufuneka lizaliswe, kwaye akufuneki kubekho ukungcola emanzini.
2. Qalisa ipompo yamanzi ukuqinisekisa ukuba umbane ohamba rhoqo, i-vacuum furnace induction coil, kunye nokujikeleza kwamanzi kwenkqubo yokupholisa i-furnace ziqhelekile, kwaye ulungise uxinzelelo lwamanzi kwixabiso elichaziweyo.
3. Jonga inkqubo yamandla epompo ye-vacuum, ibhande le-pulley yebhanti liqinile, kwaye ingaba ioyile yepompo ye-vacuum ikwindawo esembindini yomngxuma wokujonga isitywina seoyile. Emva kokuba uhlolo lugqityiwe, jikelezisa ngesandla i-pulley yebhanti ye-vacuum pump. Ukuba akukho nto ingaqhelekanga, ipompo ye-vacuum ingaqaliswa ngevalvu yebhabhathane ivaliwe.
4. Jonga imeko yomzimba wesithando somoya. Kufuneka ukuba umzimba wesithando somoya ucoceke kwinqanaba lokuqala, ikhoyili yokungenisa igqunywe kakuhle, iteyiphu yokutywina i-vacuum tape ithambile, kwaye ubungakanani bayo bufanelekile.
5. Jonga ukuba ingaba isiphatho se-lever somzimba we-vacuum furnace siyakwazi na ukuqalisa.
6. Jonga ukuba i-rotary Maxwell vacuum gauge iyahlangabezana na neemfuno.
7. Jonga ukuba izixhobo zegrafiti kunye nezincedisi zefurnace zigqityiwe na.
8. Emva kokuba amalungiselelo angentla egqityiwe, vula umbane, vala umbane we-frequency ephakathi, uze uzame ukuqalisa ukuguqulwa kwe-frequency ngokwemigaqo yokuqalisa i-frequency ephakathi. Emva kokuba uphumelele, yeka ukuguqulwa kwe-frequency ngaphambi kokuba uqalise i-furnace.
9. Imingxunya yokujonga nokulinganisa ubushushu kwisiciko esingaphezulu somzimba wesithando somoya kufuneka icocwe ngalo lonke ixesha isithando sivulwa ukuze kube lula ukujonga nokulinganisa ubushushu.
10. Xa ulayisha i-oven, iindlela zokulayisha i-oven ezifanelekileyo kufuneka zamkelwe ngokweemveliso ezahlukeneyo ezixutyiweyo. Paka iipleyiti ngokwemigaqo yokulayisha izinto ezifanelekileyo kwaye ungazitshintshi ngokuthanda kwakho.
11. Ukuze kugcinwe ubushushu obungaguqukiyo kwaye kuthintelwe imitha yobushushu, yongeza iileya ezimbini ze-carbon fiber kwi-heating crucible uze uyigqume nge-heat shield.
12. Gquma ngeteyipu yokutywina nge-vacuum.
13. Sebenzisa isiphatho se-lever, jika isigqubuthelo esiphezulu sesithando somlilo esingenamoya ukuze sidibane ngokusondeleyo nomzimba wesithando somlilo, yehlisa isigqubuthelo esiphezulu, kwaye utshixe i-fixing nut.
14. Vula kancinci ivalvu yebhabhathane uze ukhuphe umoya emzimbeni wesithando ude i-vacuum ifikelele kwixabiso elichaziweyo.
15. Emva kokuba i-vacuum degree ifikelele kwiimfuno ezichaziweyo, qalisa ukuguqulwa kwamaza, ulungise amandla amaza aphakathi, kwaye usebenze ngokwemigaqo yokusila kwezinto ezifanelekileyo; ukufudumala, ukugcinwa kobushushu kunye nokupholisa.
16. Emva kokuba ukucocwa kugqityiwe, yeka ukuguqulwa kwamaza, cofa iswitshi yokuguqula amaza okumisa, i-inverter iya kuyeka ukusebenza, ikhuphe isango lesebe lombane eliphakathi kwaye ikhuphe isango eliphambili lombane.
17. Emva kokubona ukuba isithando somlilo simnyama ngomngxuma wokujonga umzimba wesithando somlilo, vala kuqala ivalvu yebhabhathane yepompo yevacuum pump uze ukhuphe umsinga wepompo yevacuum, uze uqhagamshele amanzi empompini ukuze uqhubeke nokupholisa i-induction coil kunye nomzimba wesithando somlilo, uze ekugqibeleni uyeke ipompo yamanzi.
18. I-voltage ephakathi ye-750 volts inokubangela ukothuka ngombane. Ngexesha lonke lokusebenza kunye nenkqubo yokuhlolwa, qaphela ukhuseleko lokusebenza kwaye ungayichukumisi ikhabhinethi ye-frequency ephakathi ngezandla zakho.
19. Ngexesha lenkqubo yokusila, jonga ukuba i-arcing iyenzeka na kwi-induction coil ngokusebenzisa umngxuma wokujonga kwicala lesithando nangaliphi na ixesha. Ukuba kukho into engaqhelekanga efunyenweyo, yixele kubasebenzi abafanelekileyo ngoko nangoko ukuze bayiphathe.
20. Ivalvu yebhabhathane engenanto kufuneka iqaliswe kancinci, kungenjalo ioyile iya kuphuma ngenxa yokumpompa umoya kakhulu, nto leyo eya kuzisa iziphumo ezibi.
21. Sebenzisa i-rotary Maxwell vacuum gauge ngokuchanekileyo, kungenjalo iya kubangela iimpazamo zokufunda i-vacuum okanye ibangele ukuba i-mercury igcwale ngenxa yokusebenza kakhulu kwaye ibangele inkathazo kuluntu.
22. Nika ingqalelo ekusebenzeni ngokukhuselekileyo kwepulley yebhanti yepompo ye-vacuum.
23. Xa ufaka iteyiphu yokutywina nge-vacuum kwaye ugquma isigqubuthelo esingaphezulu somzimba wesithando, lumka ungacinezeli izandla zakho.
24. Phantsi kweemeko zokungasebenzi kakuhle kwesixhobo sokufunxa amanzi, nasiphi na isixhobo sokusebenza okanye isitya esitshintsha lula kwaye sichaphazele ucoceko lwesixhobo sokufunxa amanzi, nto leyo ebangela ukuvaleka kwemibhobho kunye nokungcoliswa kwepompo yesixhobo sokufunxa amanzi, akufuneki sifakwe kwisithando somlilo.
25. Ukuba imveliso inesixhobo sokubumba (esifana neoyile okanye iparafini), kufuneka isuswe ngaphambi kokuba itshiswe esitovini, kungenjalo iya kubangela iziphumo ezibi.
26. Ngexesha lonke lenkqubo yokusila, kufuneka kuqwalaselwe uluhlu loxinzelelo lwemitha yamanzi kunye nokujikeleza kwamanzi okupholisa ukuze kuthintelwe iingozi.
