Izilinganiso zokuvuza kwe-vacuum phakathi kokwehluleka okuvame kakhulu okomisa okomisa izimboni. Izoqalisa imiphumela engemihle ehlanganisa ukusetshenziswa kwamandla okuphezulu, imijikelezo yokomisa eyandisiwe kanye nokuwa komkhiqizo. Ukuhlolwa kwe-Static pressure-hold kuyindlela esebenza kakhulu yokuhlola ukuvuza yokuhlola ngaphambi kokuthunyelwa kanye nokugada kwansuku zonke kwesizinda sezitshalo, okungahlola izinga lokuvuza lilonke ngaphandle kwezitholi zokuvuza ezikhethekile ezibizayo.
Inqubo yokusebenza egcwele: ngemva kokuhlanganisa ngokugcwele noma ukulungiswa kwangemuva kwenqwaba, vala ngokuqinile umnyango wegumbi. Qala amaphampu e-vacuum bese udonsa igumbi phansi ukuze uqondise i-vacuum yokugcina. Ngemva kokufinyelela inani elimisiwe le-vacuum, vala wonke amaphampu e-vacuum futhi uvale ama-vacuum valve ukuze uwahlukanise ngokugcwele amayunithi e-vacuum. Qala isikhathi futhi urekhode ingcindezi-ikhuphuke inani ngaphakathi kwegumbi phakathi nesikhathi esinqunyiwe.
Imibandela yokwamukela iyahlukahluka kumayunithi anosayizi ohlukile. Ireferensi evamile yezomiso eziqandisayo zezimboni zezinga lokudla: ngaphansi kwesimo sezinga lokushisa kwegumbi, ngemva kokuhlukanisa iqembu le-vacuum, ukucindezela-ukukhuphuka Ngaphansi noma okulingana no-15Pa phakathi nemizuzu engama-30 kusho ukusebenza okuhle kakhulu; 15‑40Pa pressure-rise iwela ebangeni elamukelekayo; ukucindezela-ukukhuphuka ngaphezu kwe-40Pa kubonisa ukuvuza okusobala futhi nokuhlolwa kwephoyinti elivuzayo kuzokwenziwa.
Gxila ezindaweni ezivuzayo njalo: ① umucu wokuvala we-silicone wegumbi nendawo yokuxhumana evalekayo, hlola udoti, imihuzuko, ukuguga nokuqhekeka; ② ama-gaskets welunga ngalinye le-flange; ③ izixhumi zepayipi levacuum; ④ ukuvala izindandatho vacuum valve; ⑤ iwindi lokubuka nezimbobo zokukhweza inzwa odongeni lwegumbi.
Amathiphu: Ungawenzi ukuhlolwa kwengcindezi egunjini elishisayo ngemva nje kokukhiqiza. Linda kuze kube yilapho igumbi liphola ngokuphelele ekamelweni lokushisa, ngoba ukunwetshwa kwe-thermal nokufinyela kuzophazamisa ukufundwa kwengcindezi. Gwema ukuhlolwa ngaphansi komoya onamandla noma ukushintshashintsha kwezinga lokushisa okubukhali kwe-ambient okuphazamisa imiphumela yokuhlolwa.
Ukuhlolwa kokubamba ingcindezi kungahlulela ukuthi ukuvuza sekukonke kukhona yini, kodwa akukwazi ukukhomba indawo yokuvuza okuyiyonayona. Uma umphumela wokubamba ingcindezi wehluleka, thola ukuvuza kwesifutho ukuze uthole izindawo ezivuzayo ezithile. Qalisa kabusha ukuhlolwa kwengcindezi yokubamba ngemva kokulungisa ukuze uqinisekise inkomba efanelekayo. Ukuqapha okujwayelekile kwengcindezi kusiza ukuthola izingozi zokuguga ezifihliwe zezingxenye zokuvala kusenesikhathi futhi kuvimbele ukuwohloka okungazelelwe ngesikhathi sokukhiqiza.
