Iindaba

Kwicandelo lobuchwepheshe banamhlanje bokuphosa, oomatshini bokuphosa ngoxinzelelo lwe-vacuum bathandwa kakhulu ngenxa yokukwazi kwabo ukuphucula umgangatho we-castings ngempumelelo. Phakathi kwabo, ukudala indawo ye-vacuum linyathelo elibalulekileyo lokusebenza, elibandakanya uthotho lwezoyilo ezintsonkothileyo kunye nemisebenzi yokusebenzisana kwezobuchwepheshe.

Inyathelo lokuqala ekudaleni indawo yokukhupha umoya ngomatshini wokuphosa uxinzelelo lwe-vacuum kukwakha inkqubo yokuvala. Lonke umgodi wezixhobo zokuvala umoya, kuquka i-crucible equlethe isinyithi esinyibilikisiweyo, umgodi we-mold apho kukho khona i-mold, kunye nemibhobho yokudibanisa, kufuneka iqinisekise izinga eliphezulu lokuvala umoya. Izixhobo zokuvala ezisemgangathweni ophezulu, ezifana neeringi zokuvala zerabha ezikhethekileyo, zihlala zisetyenziswa kwaye zifakelwe kwiindawo zokudibanisa iindawo ezahlukeneyo zokudibanisa kunye nezinto ezihambayo ukuthintela umoya ukuba ungangeni ngexesha lenkqubo yokupompa i-vacuum. Umzekelo, ekudibaneni komnyango we-oven kunye nomgodi, umngxuma wokuvala owenziwe ngononophelo odityaniswe neringi yokuvala enobukhulu obufanelekileyo kunye nezinto zinokwenza ujongano oluthembekileyo lokuvala emva kokuvala ucango lwe-oven, zibeke isiseko semisebenzi elandelayo yokukhupha i-vacuum.

oomatshini bokuphosa uxinzelelo lwe-vacuum

Okulandelayo, inkqubo yokumpompa i-vacuum idlala indima ephambili. Inkqubo yokumpompa i-vacuum ikakhulu iqulathe ipompo ye-vacuum, imibhobho enxulumene nayo, kunye neevalvu. Ipompo ye-vacuum ngumthombo wamandla wokuvelisa i-vacuum, kwaye eziqhelekileyo ziquka iipompo ze-vacuum ze-rotary vane, iipompo ze-Roots vacuum, njl. Emva kokuba ipompo ye-vacuum iqalisiwe, iqhagamshelwe kwigumbi lomatshini wokuphosa ngepayipi kwaye iqala ukukhupha umoya kwigumbi. Kwinqanaba lokuqala lokukhupha umoya, umoya ongaphakathi kwigumbi uxineneyo, kwaye ipompo ye-vacuum ikhupha umoya omninzi ngesantya esiphezulu sokukhupha. Njengoko umoya ongaphakathi kwigumbi usiba mncinci kancinci, imeko yokusebenza yepompo ye-vacuum iya kulungiswa ngokweemfuno ze-vacuum degree ezimiselweyo ukugcina isantya sokumpompa esizinzileyo kunye ne-vacuum degree yokugqibela. Umzekelo, ipompo ye-vacuum ye-rotary vane isebenzisa ii-blades ezijikelezayo ngaphakathi ukutsala nokucinezela umoya kwi-intake port, kwaye emva koko uyikhuphe kwi-exhaust port, ijikeleza rhoqo kwaye inciphise uxinzelelo lomoya ngaphakathi kwigumbi.

Ukulinganiswa kunye nokubekwa esweni kweqondo lokucoca umoya kubalulekile kwinkqubo yokucoca umoya. Umatshini wokuphosa uxhotyiswe nge-vacuum gauge echanekileyo, elinganisa iqondo lokucoca umoya ngaphakathi kwigumbi ngexesha langempela kwaye ibuyisele idatha kwinkqubo yolawulo. Inkqubo yolawulo ilawula ngokuchanekileyo ukusebenza kwepompo yokucoca umoya ngokusekelwe kwixabiso elimiselweyo lethagethi yokucoca umoya. Umzekelo, ukuba iqondo lokucoca umoya elilinganisiweyo alikafikeleli kumgangatho omiselweyo, inkqubo yolawulo iya kwandisa amandla epompo yokucoca umoya okanye yandise ixesha lokumpompa; Nje ukuba inqanaba lokucoca umoya elijoliswe kulo lifikelelwe, ipompo yokucoca umoya iya kungena kwimeko yokusebenza yokulungisa ukuqinisekisa uzinzo lwendawo yokucoca umoya. Ngokubanzi, iqondo lokucoca umoya elinokufikelelwa ngumatshini wokucoca umoya linokuba liphantsi njengee-pascals ezilishumi okanye lingaphantsi. Indawo yokucoca umoya ephezulu kangaka inokususa ngokufanelekileyo ukungcola kwegesi kwindawo yokubumba, inciphise ukubandakanyeka kwegesi kulwelo lwesinyithi ngexesha lenkqubo yokuthulula, kwaye iphucule kakhulu umgangatho wokucoca, iphephe ukwenzeka kweziphene ezifana nokuvuleka kunye nokungakhululeki.

Ukongeza, ukuze kuphuculwe ngakumbi imeko-bume ye-vacuum kwaye kuqinisekiswe ukuthembeka kwayo, umatshini wokuphosa uxinzelelo lwe-vacuum ukwaxhotyiswe ngezixhobo ezincedisayo kunye neendlela zokukhusela ukhuseleko. Umzekelo, izihluzo zifakelwa kumbhobho wokukhupha umoya ukuthintela uthuli, ukungcola, njl.njl. ukuba kungangeni kwimpompo ye-vacuum kwaye kuchaphazele ukusebenza kwayo kunye nobomi benkonzo; Kwangaxeshanye, ixhotyiswe ngesixhobo sokufumanisa ukuvuza kwe-vacuum, esinokubona ngokukhawuleza ukuba kukho ukuvuza okuncinci kwindawo yokuvala kwaye sikhuphe i-alamu yokulungiswa ngexesha elifanelekileyo. Kwakhona, iivalvu zokujonga zihlala zifakelwa kwindawo yokungena kunye neyokuphuma yeempompo ze-vacuum ukuthintela ukubuyela kwegesi kunye nokuqinisekisa ukusebenza okuqhelekileyo kwenkqubo ye-vacuum.

Iumatshini wokuphosa uxinzelelo lwe-vacuumidale ngempumelelo indawo yokukhupha umoya ehlangabezana neemfuno zenkqubo yokuphosa ngokusebenzisa inkqubo ebanzi yokutywina, inkqubo yokupompa umoya enamandla, ukulinganisa nokubeka esweni ngokuchanekileyo i-vacuum, kunye nothotho lwezixhobo ezincedisayo kunye neendlela zokukhusela ukhuseleko. Le ndawo yokukhupha umoya ibonelela ngeemeko ezilungileyo kakhulu zokuthululwa nokwenziwa kwesinyithi esinyibilikisiweyo kwindawo yokubumba, nto leyo ekhokelela ekuphuculweni okukhulu koxinano, iimpawu zoomatshini, kunye nomgangatho womphezulu weemveliso ezibunjiweyo. Ikhuthaza ngempumelelo uphuhliso lweshishini lokukhupha umoya ukuya kumgangatho ophezulu kunye nokuchaneka, kwaye idlala indima ebalulekileyo kwiinkalo ezininzi ezifana neenqwelo-moya, ukuveliswa kweemoto, kunye nobucwebe.
