Emkhakheni wobuchwepheshe besimanje bokuphonsa, imishini yokukhipha ingcindezi ye-vacuum ithandwa kakhulu ngenxa yekhono layo lokuthuthukisa ngempumelelo ikhwalithi yokulingisa. Phakathi kwazo, ukudala indawo engenalutho kuyisinyathelo esibalulekile sokusebenza, esibandakanya uchungechunge lwemiklamo eyinkimbinkimbi kanye nokusebenza ngokubambisana kwezobuchwepheshe.

Isinyathelo sokuqala sokwenza indawo ye-vacuum ngomshini wokukhipha ingcindezi ye-vacuum ukwakhiwa kwesistimu yokuvala uphawu. Wonke umgodi wezinto zokuphonsa, kuhlanganise ne-crucible equkethe insimbi encibilikisiwe, imbobo yesikhunta lapho isikhunta sikhona, kanye namapayipi axhumayo, kufanele kuqinisekise izinga eliphezulu lokuvala. Izinto zokuvala zekhwalithi ephezulu, njengezindandatho ezikhethekile zokuvala zenjoloba, zivame ukusetshenziswa futhi zifakwe emajoyini ezingxenye ezihlukahlukene zokuxhuma kanye nezingxenye ezihambayo ukuze kuvinjelwe umoya ekungeneni phakathi nenqubo yokupompa i-vacuum. Isibonelo, lapho kuhlangana khona umnyango wesithando somlilo kanye nembobo, i-groove yokuvala eklanywe ngokucophelela ehlanganiswe nendandatho yokuvala yobukhulu obufanele kanye nempahla ingakha isikhombimsebenzisi sokuvala esithembekile ngemva kokuvala umnyango wesithando somlilo, ibeka isisekelo semisebenzi yokukhipha i-vacuum elandelayo.

imishini yokukhipha ingcindezi ye-vacuum

Okulandelayo, uhlelo lokumpompa i-vacuum ludlala indima emaphakathi. Isistimu yokumpompa i-vacuum ngokuyinhloko iqukethe ipompo ye-vacuum, amapayipi ahlobene, nama-valve. Iphampu yevacuum iwumthombo wamandla okukhiqiza isivacu, futhi evamile ihlanganisa amaphampu evacuum e-rotary vane, amaphampu e-vacuum e-Roots, njll. Ngemva kokuthi isiqalile iphampu, ixhunywa egumbini lomshini wokuphonsa ngepayipi futhi iqala ukukhipha. umoya ovela ekamelweni. Esigabeni sokuqala sokukhishwa komoya, umoya ongaphakathi kwegumbi uminyene, futhi iphampu ye-vacuum ikhipha inani elikhulu lomoya ngenani eliphezulu lokukhipha. Njengoba umoya ongaphakathi egunjini uya uba mncane kancane, isimo sokusebenza sephampu ye-vacuum sizolungiswa ngokuvumelana nezidingo zedigri ye-vacuum esethiwe ukuze kugcinwe isivinini sokumpompa esizinzile kanye ne-vacuum degree yokugcina. Isibonelo, iphampu ye-rotary vane vacuum isebenzisa ama-blade azungezisayo ngaphakathi ukuze idonse futhi iminyanise umoya ovela endaweni yokukhipha umoya, bese iwukhipha ku-exhaust port, izungeza ngokuqhubekayo futhi yehlise umfutho womoya ngaphakathi kwegumbi.

Ukukalwa nokuqapha kweziqu ze-vacuum kubalulekile ohlelweni lokuhlanza. Umshini wokuphonsa ufakwe igeji ye-vacuum yokunemba okuphezulu, ekala idigri ye-vacuum ngaphakathi kwegumbi ngesikhathi sangempela futhi ibuyisele idatha ohlelweni lokulawula. Isistimu yokulawula ilawula ngokunembile ukusebenza kwepompo yevacuum ngokusekelwe kunani elihlosiwe le-vacuum. Isibonelo, uma idigri ye-vacuum elinganisiwe ingakafinyeleli ezingeni elinqunywe kusengaphambili, isistimu yokulawula izokwandisa amandla wepompo ye-vacuum noma yandise isikhathi sokupompa; Uma izinga le-vacuum elihlosiwe selifinyelelwe, iphampu yevacuum izongena esimweni sokusebenza sokulungisa ukuze kuqinisekiswe ukuzinza kwendawo yevacuum. Ngokuvamile, idigri ye-vacuum engafinyelelwa umshini wokukhipha ingcindezi ingaba ngaphansi njengamashumi ama-pascals noma ibe ngaphansi. Imvelo enjalo ye-vacuum ephezulu ingasusa ngokuphumelelayo ukungcola kwegesi emgodini wesikhunta, inciphise ukubandakanyeka kwegesi oketshezini lwensimbi ngesikhathi sokuthulula, futhi ithuthukise kakhulu ikhwalithi yokusakazwa, ukugwema ukuvela kweziphambeko ezifana ne-porosity nokuxega.

Ngaphezu kwalokho, ukuze kuqhutshekwe nokwandisa indawo ye-vacuum nokuqinisekisa ukwethembeka kwayo, umshini wokukhipha umfutho we-vacuum nawo ufakwe ezinye izisetshenziswa ezisizayo nezindlela zokuvikela ukuphepha. Isibonelo, izihlungi zifakwa epayipini lokukhipha umoya ukuze kuvinjelwe uthuli, ukungcola, njll. ukuthi kungamuncwa empompini yevacuum futhi kuthinte ukusebenza kwayo nempilo yesevisi; Ngesikhathi esifanayo, ifakwe idivayisi yokuthola ukuvuza kwe-vacuum, engakwazi ukubona ngokushesha ukuthi kukhona yini ukuvuza okuncane engxenyeni yokuvala futhi ikhiphe i-alamu ukuze ilungiswe ngesikhathi. Futhi, ama-valve okuhlola avame ukufakwa endaweni yokungena nokuphuma kwamaphampu e-vacuum ukuvimbela ukugeleza kwegesi futhi kuqinisekiswe ukusebenza okuvamile kwesistimu ye-vacuum.

Iumshini wokukhipha ingcindezi ye-vacuumidale ngempumelelo indawo ye-vacuum ehlangabezana nezidingo zenqubo yokuphonsa ngohlelo olubanzi lokuvala, uhlelo olunamandla lokumpompa i-vacuum, ukulinganisa okunembile kwe-vacuum kanye nokuqapha, kanye nochungechunge lwamadivayisi asizayo nezindlela zokuvikela ukuphepha. Le ndawo ye-vacuum ihlinzeka ngezimo ezivumayo kakhulu zokuthululwa nokwakhiwa kwensimbi encibilikisiwe emgodini wesikhunta, okuholela ekuthuthukisweni okuphawulekayo kokuminyana, izakhiwo zemishini, kanye nekhwalithi yangaphezulu yemikhiqizo ekhonjiwe. Ikhuthaza ngempumelelo ukuthuthukiswa kwemboni yokulingisa iye kwikhwalithi ephezulu nokunemba, futhi idlala indima ebalulekile emikhakheni eminingi efana ne-aerospace, ukukhiqizwa kwezimoto, nobucwebe.
