Vuto la ng'anjo ya vacuum sintering ndi ng'anjo yomwe imagwiritsa ntchito kutentha kwa induction poteteza kutentha kwa zinthu. Iwo akhoza kugawidwa mu mphamvu pafupipafupi, sing'anga pafupipafupi, mkulu pafupipafupi ndi mitundu ina, ndipo akhoza m'gulu la ng'anjo vacuum sintering. Vuto la vacuum induction sintering ng'anjo ndi zida zonse zomwe zimagwiritsa ntchito mfundo yotenthetsera yapakatikati-pang'onopang'ono kutenthetsa sinter simenti yodula mitu ya carbide ndi ma compact zitsulo amitundu yosiyanasiyana pansi pa vacuum kapena malo otetezedwa. Amagwiritsidwa ntchito popanga simenti ya carbide, zitsulo za dysprosium, ndi zida za ceramic. Zapangidwira kupanga mafakitale.
Ndiye, timagwiritsa ntchito bwanji ng'anjo ya vacuum sintering mosamala?
1. Gwero lamadzi ozizira lamagetsi apakati pafupipafupi, thupi la ng'anjo ya vacuum, ndi koyilo yolowetsamo - nkhokwe yamadzi iyenera kukhala yodzaza, ndipo pasakhale zonyansa m'madzi. ng'anjo ya vacuum
2. Yambitsani mpope wamadzi kuti muwonetsetse kuti magetsi apakati pafupipafupi, koyilo ya ng'anjo ya vacuum, ndi kayendedwe ka madzi ka ng'anjo ya ng'anjo ndi yachilendo, ndikusintha kuthamanga kwa madzi ku mtengo wotchulidwa.
3. Yang'anani mphamvu ya pampu ya vacuum, lamba wa pulley ndi wothina, komanso ngati mafuta a pampu ya vacuum ali pakatikati pa dzenje lowonera chisindikizo chamafuta. Kuyang'anira kukamalizidwa, tembenuzani pamanja kapu ya lamba wa vacuum pump. Ngati palibe chovuta, pampu ya vacuum ikhoza kuyambika ndi valavu ya butterfly yotsekedwa.
4. Yang'anani momwe thupi la ng'anjo likukhalira. Ndikofunikira kuti thupi la ng'anjo ya vacuum likhale laukhondo wamba, koyilo yolowera ndi induction bwino, tepi yotsekera yotsekera ndi yotanuka, ndipo kukula kwake ndikoyenera.
5. Yang'anani ngati chogwirira cha ng'anjo ya vacuum ndichosavuta kuti chiyambe.
6. Onani ngati rotary vacuum gauge ya Maxwell ikukwaniritsa zofunikira.
7. Onani ngati ma graphite crucible ndi zida za ng'anjo zatha.
8. Pambuyo pokonzekera pamwambapa, tsegulani magetsi, kutseka magetsi apakati, ndipo yesetsani kuyambitsa kutembenuka kwafupipafupi malinga ndi malamulo apakati oyambira. Pambuyo bwino, kusiya pafupipafupi kutembenuka musanayambe ng'anjo.
9. Mabowo owonetsetsa ndi kutentha omwe ali pachivundikiro chapamwamba cha ng'anjo ya vacuum ayenera kutsukidwa nthawi zonse pamene ng'anjo imatsegulidwa kuti ziwongolere kuyang'ana ndi kuyeza kutentha.
10. Pokweza ng'anjo, njira zotsatsira ng'anjo zofananira ziyenera kutengedwa molingana ndi zinthu zosiyanasiyana zopangira sintered. Nyamulani mbalezo molingana ndi malamulo okweza zinthu ndipo musawasinthe mwakufuna kwawo.
11. Kuti mukhale ndi kutentha kosalekeza ndikupewa kutentha kwa kutentha, onjezerani zigawo ziwiri za carbon fiber ku crucible yotentha ndikuyiphimba ndi chishango cha kutentha.
12. Phimbani ndi tepi yosindikiza vacuum.
13. Gwiritsani ntchito chogwirira cha lever, tembenuzirani chivundikiro chapamwamba cha ng'anjo ya vacuum kuti mugwirizane kwambiri ndi thupi la ng'anjo, tsitsani chivundikiro chapamwamba, ndi kutseka mtedza wokonza.
14. Pang'onopang'ono tsegulani valavu ya gulugufe ndikuchotsa mpweya kuchokera ku ng'anjo yamoto mpaka mpweya ufika pamtengo wotchulidwa.
15. Pambuyo pa digiri ya vacuum ikufika pa zofunikira zomwe zafotokozedwa, yambani kutembenuka kwafupipafupi, sinthani mphamvu yapakati yapakati, ndikugwira ntchito molingana ndi malamulo a sintering a zipangizo zoyenera; kutentha, kuteteza kutentha ndi kuziziritsa.
16. Sintering ikamalizidwa, siyani kutembenuka kwafupipafupi, kanikizani kutembenuka kwafupipafupi kuyimitsa, inverter imasiya kugwira ntchito, kulumikiza chipata chapakatikati chanthambi ndikuchotsa chipata chachikulu chamagetsi.
17. Pambuyo powona kuti ng'anjoyo ndi yakuda kupyolera mu dzenje la ng'anjo yamoto, choyamba mutseke vacuum mpope butterfly valve ndikudula pampu ya vacuum panopa, kenako gwirizanitsani madzi apampopi kuti mupitirize kuziziritsa koyilo yolowera ndi ng'anjo, ndipo potsirizira pake muyimitse mpope wa madzi.
18. Kuthamanga kwapakati pafupipafupi kwa 750 volts kungayambitse kugwedezeka kwamagetsi. Panthawi yonse yogwira ntchito ndikuwunika, samalani zachitetezo chogwira ntchito ndipo musakhudze kabati yapakati pafupipafupi ndi manja anu.
19. Panthawi ya sintering, onani ngati arcing imapezeka mu coil induction kupyolera mu dzenje loyang'ana pambali pa ng'anjo nthawi iliyonse. Ngati pali vuto lililonse lapezeka, dziwitsani ogwira nawo ntchito nthawi yomweyo kuti athetse.
20. Vacuum butterfly valve iyenera kuyambika pang'onopang'ono, apo ayi mafuta amatha kutuluka chifukwa cha kupopa kwa mpweya wambiri, zomwe zidzabweretse zotsatira zoipa.
21. Gwiritsani ntchito rotary vacuum gauge ya Maxwell molondola, apo ayi izi zingayambitse zolakwika pakuwerenga kwa vacuum kapena kupangitsa kuti mercury kusefukira chifukwa chogwira ntchito mopitilira muyeso ndikuyambitsa vuto la anthu.
22. Samalani ntchito yotetezeka ya pulley ya lamba ya vacuum pump.
23. Mukamagwiritsa ntchito tepi yosindikiza vacuum ndikuphimba chivundikiro chapamwamba cha ng'anjo, samalani kuti musatsine manja anu.
24. Pansi pa vacuum, chogwirira ntchito kapena chidebe chilichonse chomwe chimasungunuka mosavuta ndipo chimakhudza ukhondo wa vacuum, zomwe zimapangitsa kutsekeka kwa mapaipi ndi kuipitsidwa kwa pampu ya vacuum, siziyenera kuyikidwa mu ng'anjo.
25. Ngati mankhwalawa ali ndi chopangira chopangira (monga mafuta kapena parafini), chiyenera kuchotsedwa chisanatenthedwe mu ng'anjo, mwinamwake chidzabweretsa zotsatirapo zoipa.
26. Pa nthawi yonse ya sintering, chidwi chiyenera kuperekedwa ku kuthamanga kwa mita ya madzi ndi kuyendayenda kwa madzi ozizira kuti tipewe ngozi.
