Yiziphi izinyathelo eziphuthumayo zamaphutha ahlukahlukene we-vacuum furnace?Lezi zinyathelo eziphuthumayo ezilandelayo zizothathwa ngokushesha uma kwenzeka ugesi uphela kungazelelwe, ukunqanyulwa kwamanzi, ukunqanyulwa komoya okucindezelwe kanye nezinye izimo eziphuthumayo: okuhlanganisa i-nitrogen ephuthumayo namanzi okupholisa aphuthumayo.Izinyathelo eziyinhloko ezithathiwe yilezi:

I-1, Lapho igumbi lokufudumeza lishiswa futhi licishwa
1).cisha amandla aphelele wemishini ngokushesha.
2).vala i-vacuum valve yepayipi ngalinye ukuvimbela umoya ukuthi ungangeni esithandweni somlilo.
3).i-nitrogen ehlanzekile kakhulu yokushisa igumbi lokungena komoya ku-6.6 × 10-4 pholisa isithando somlilo ngokushesha ngangokunokwenzeka Ngesikhathi esifanayo, ngenisa umoya ekamelweni lokupholisa kusengaphambili ukuze ushise i-valve yesango.
4).uma amanzi abuyisiwe esetshenziselwa ukupholisa kanye nokuphakelwa kwamanzi, amanzi abekwe eceleni (amanzi ompompi noma ichibi) azosetshenziswa.
2. Lapho igumbi lokushisa lishisa amanzi
1).unqamule amandla okushisa ngokushesha.
2).vumela amanzi alindile.
3).dlulisela i-workpiece kusuka ekamelweni lokushisa kuya ekamelweni lokupholisa, futhi ugcwalise i-nitrogen ukuze upholise ngokushesha izingxenye.
4).gcwalisa i-nitrogen ehlanzekile futhi ushise igumbi ukuze lipholise ngokushesha libe ngaphansi kuka-150.
3, Ukuvuza okuyingxenye kwenzeka lapho igumbi lokushisa lishiswa
1).xhuma ngokushesha indawo yokuvuza ngosimende we-vacuum.
2).unqamule amandla okushisa ngokushesha.
3).igumbi lokushisa lizogcwaliswa ngokushesha nge-nitrogen ephezulu yokuhlanzeka ukwenza ukucindezela phambi kwesithando somlilo eduze nezinga lokuqala, ukuze kuncishiswe ukungena komoya.
4. Ukusebenza kokugeleza
1).uma kungekho manzi noma ukucindezela kwamanzi okwanele isikhathi esifushane, uhlelo lwe-alamu oluzwakalayo nolubonakalayo lunganikezwa, kodwa umsebenzi ngeke uthinteke.Ingaqhubeka nokusebenza ngaphansi kwezimo ezijwayelekile.
2).uma ukuhlinzekwa kwamanzi kunqanyuliwe noma ukucindezela kwamanzi kunganele, futhi kulinganiselwa ukuthi isimo sizodlula imizuzu engu-20, ukushisa kuzomiswa ngokushesha.Uma umfutho wamanzi ubuyela kokujwayelekile, qala ukushisa ukusuka ku-zero.Ngalesi sikhathi, kufanele kusekelwe ku-curve yenqubo efanayo lapho izinga lokushisa lekamelo lokushisa lilungile.
5. Ukusebenza kwamandla
Isistimu yamandla, wonke ama-valve omoya azovalwa ngokushesha Uma kwenzeka "ukudla" noma "ukondla" ngesikhathi sokuhluleka kwamandla, izindlela ezithile zokujezisa mahhala zimi kanje:
1).lapho uhlangabezana nenqubo "yokondla", shintsha "umsebenzi" uye kwimodi "yemanuwali".Ngemva kokushaya ucingo, sebenzisa ukhiye wokusebenza owenziwe ngesandla ukuze uqedele “inqubo yokondla”, bese ushintsha “ibhukwana” libe “umsebenzi”, futhi uqhubeke nokusebenza ngokwendinganiso evamile.
2).lapho uhlangabezana nenqubo "yokondla", sebenzisa ngokushesha abantu ukususa izinto, futhi uvale i-valve yesango ndawonye nabantu.Ngemva kokushaya ucingo, qala kusukela ekuqaleni komsebenzi wokuqala.Lokhu okubizwa ngokuthi "umuntu" ukwenza umshini usebenze ngokuzenzakalelayo ngokuxhawula ngaphansi kwe-DC motor noma umsila wensimbi.
