Iindaba

Kwinkalo yetekhnoloji yetekhnoloji yanamhlanje, oomatshini bokuphosa uxinzelelo lwe-vacuum bathandwa kakhulu ngenxa yokukwazi kwabo ukuphucula ngokufanelekileyo umgangatho wokuphosa. Phakathi kwabo, ukudala indawo yokuphumla linyathelo eliphambili lokusebenza, elibandakanya uluhlu lwezoyilo eziphucukileyo kunye nokusebenza ngokubambisana kwezobuchwepheshe.

Isinyathelo sokuqala ekudaleni indawo ye-vacuum kunye nomshini wokukhupha uxinzelelo lwe-vacuum kukwakhiwa kwenkqubo yokutywina. Umgodi wonke wesixhobo sokuphosa, kubandakanywa i-crucible equkethe isinyithi esityhidiweyo, i-mold cavity apho i-mold ikhona, kunye nemibhobho yokudibanisa, kufuneka iqinisekise izinga eliphezulu lokutywinwa. Izinto zokutywina ezikumgangatho ophezulu, ezifana nezangqa ezikhethekileyo zokutywinwa kweerubha, zidla ngokusetyenziswa kwaye zifakwe kwiindawo ezidibeneyo zokudibanisa iindawo ezahlukeneyo kunye namacandelo ahambayo ukukhusela umoya ukuba ungangeni ngexesha lenkqubo yokupompa i-vacuum. Ngokomzekelo, ekudibaneni komnyango wesithando somlilo kunye ne-cavity, i-groove yokutywina eyenziwe ngokucokisekileyo idibaniswe nendandatho yokutywina yobukhulu obufanelekileyo kunye nezinto eziphathekayo zingenza i-interface ethembekileyo yokutywinwa emva kokuvala umnyango wesithando somlilo, ukubeka isiseko semisebenzi yokukhupha i-vacuum elandelayo.

oomatshini bokuphosa uxinzelelo lwevacuum

Emva koko, inkqubo yokumpompa i-vacuum idlala indima ephambili. Inkqubo yokumpompa ivacuum ikakhulu inempompo yokufunxa, imibhobho enxulumeneyo, kunye neevalvu. Impompo yokufutha ngumthombo wamandla wokuvelisa isifunxa, kwaye eziqhelekileyo ziquka iimpompo zokucoca ezijikelezayo, iimpompo zokufunxa iingcambu, njl njl. Emva kokuba impompo yokufutha iqalisiwe, iqhagamshelwa kwigumbi lomatshini wokulahla ngombhobho kwaye iqalise ukutsala. umoya ovela kwigumbi. Kwinqanaba lokuqala lokukhutshwa komoya, umoya ngaphakathi kwegumbi unzima kakhulu, kwaye i-vacuum pump extracts ikhupha inani elikhulu lomoya kwizinga eliphezulu lokukhupha. Njengoko umoya ongaphakathi kwigumbi uya usiba mncinci, imeko yokusebenza yempompo yokufunxa iya kulungelelaniswa ngokweemfuno zedigri yevacuum esele isetyenzisiwe ukuze kugcinwe isantya sokupompa esizinzile kunye nesidanga sokugqibela sokufunxa. Umzekelo, i-rotary vane vacuum pump isebenzisa ii-blades ezijikelezayo zangaphakathi ukutsala kunye nokucinezela umoya kwi-port yokungena, kwaye emva koko uyikhuphe kwi-exhaust port, ngokuqhubekayo ukujikeleza kunye nokunciphisa uxinzelelo lomoya ngaphakathi kwegumbi.

Umlinganiselo kunye nokujongwa kwesidanga sevacuum kubalulekile kwinkqubo yokucoca. Umatshini wokuphosa uxhotyiswe nge-vacuum gauge ephezulu, elinganisa idigri ye-vacuum ngaphakathi kwegumbi ngexesha langempela kwaye ibuyisele idatha kwinkqubo yokulawula. Inkqubo yokulawula ilawula ngokuchanekileyo ukusebenza kwempompo ye-vacuum ngokusekelwe kwixabiso elijoliswe kuyo. Ngokomzekelo, ukuba iqondo le-vacuum elilinganisiweyo alikafiki kwinqanaba elimiselweyo, inkqubo yokulawula iya kwandisa amandla epompo yokucoca okanye ukwandisa ixesha lokupompa; Nje ukuba inqanaba le-vacuum elijoliswe kuyo lifikeleleke, ipompo yokufunxa iya kungena kwindawo yokusebenza yolondolozo ukuqinisekisa ukuzinza kwendawo yokucoca. Ngokubanzi, idigri yevacuum enokufikelela kumatshini wokucoca ivacuum inokuba sezantsi amashumi epascals okanye ngaphantsi. Imeko enjalo ye-vacuum ephezulu inokususa ngokufanelekileyo ukungcola kwegesi kwi-mold cavity, ukunciphisa ukubandakanyeka kwegesi kulwelo lwetsimbi ngexesha lokugalela, kwaye iphucule kakhulu umgangatho wokuphosa, ukuphepha ukwenzeka kweziphene ezifana ne-porosity kunye nokukhululeka.

Ukongezelela, ukwenzela ukuba uqhubele phambili ukunyusa indawo ye-vacuum kunye nokuqinisekisa ukuthembeka kwayo, umatshini wokukhupha uxinzelelo lwe-vacuum uxhotyiswe nezinye izixhobo ezincedisayo kunye neendlela zokukhusela ukhuseleko. Ngokomzekelo, izihlungi zifakwe kumbhobho wokukhupha ukukhusela uthuli, ukungcola, njl. Ngexesha elifanayo, lixhotyiswe ngesixhobo sokukhangela ukuvuza kwe-vacuum, enokuthi ibone ngokukhawuleza ukuba kukho ukuvuza okuncinci kwindawo yokutywinwa kwaye ikhuphe i-alamu yokulungiswa kwangexesha. Kwakhona, ii-valve zokujonga zivame ukufakwa kwindawo yokungena kunye nokuphuma kweepompo zokucoca ukukhusela i-gas backflow kunye nokuqinisekisa ukusebenza okuqhelekileyo kwenkqubo yokucoca.

Iumatshini wokuphosa uxinzelelo lwevacuumuye wadala ngempumelelo indawo ye-vacuum ehlangabezana neemfuno zenkqubo yokuphosa ngokusebenzisa inkqubo yokutywina ebanzi, inkqubo yokumpompa i-vacuum enamandla, ukulinganisa okuchanekileyo kunye nokubeka iliso, kunye nochungechunge lwezixhobo ezincedisayo kunye neendlela zokukhusela ukhuseleko. Lo mmandla wevacuum ubonelela ngeemeko ezilunge kakhulu zokugalelwa kunye nokwenziwa kwesinyithi esinyibilikisiweyo kumgodi wokungunda, okukhokelela kuphuculo olubonakalayo kuxinaniso, iipropathi zoomatshini, kunye nomgangatho womphezulu weemveliso ezityhidiweyo. Ikhuthaza ngempumelelo uphuhliso lweshishini lokuphosa ukuya kumgangatho ophezulu kunye nokuchaneka, kwaye idlala indima ebaluleke kakhulu kwiinkalo ezininzi ezifana ne-aerospace, ukuveliswa kweemoto, kunye nobucwebe.
