Abasebenzisi bepompo ye-vacuum akumele bangabazi ubungozi bempushana. Iphampu ye-vacuum njengemishini enembayo izwela kakhulu kumpushana. Uma impushana ingena empompini yevacuum ngesikhathi sokusebenza, izodala ukuguga nokudabuka kwepompo. Ngakho-ke amaphampu amaningi e-vacuum azofakaizihlungi zokungenaukuhlunga impushana.
Kodwa-ke, lapho inani lempushana likhulu, ukuhlunga kuba yinkinga ekhohlisayo. Amandla okuhlunga ekhatriji yesihlungi anomkhawulo, ikakhulukazi amanye amakhatriji esihlungi avamile emakethe. Abakwazi ukubhekana nenkinga. Mhlawumbe ezigabeni zokuqala zokusetshenziswa, konke kuhamba ngendlela evamile. Kodwa ngemva kwesikhathi esifushane sokusetshenziswa, uzothola ukuthi isici sokuhlunga sivinjiwe, futhi wehlise isivinini sokupompa. Kungase kuholele ekuvaleni kwephampu yevacuum. Okubi kakhulu ukuthi impushana ingena empompini yevacuum bese ilimaza njengoba sishilo ngenhla.
Isixazululo esilula ukufaka esikhundleni sesici sokuhlunga. Kodwa futhi kuyindlela enzima kakhulu ngenxa yezidingo zokushintshwa njalo. Ngaphandle kwalokho, izindleko zayo ziphezulu kakhulu. Ungase udinge ukushintsha sonke isihlungi.Isihlungi se-Blowbackzivela njengoba izikhathi zidinga ukuxazulula le nkinga ngempumelelo.
Uma kuqhathaniswa nezinto ezijwayelekile zokuhlunga, umehluko omkhulu wesihlungi se-blowback ukwengezwa kwembobo ye-blowback endaweni yayo yokukhipha umoya kanye nokukhipha amanzi ngaphansi kwayo. Ngaphansi kwezimo ezivamile zokusebenza, igesi ingena isuka endaweni yokungena, idlule endaweni yokuhlunga, bese iphuma embotsheni yokukhipha umoya. Uma iphampu ye-vacuum ingena kumodi yokulinda noma ivala shaqa, singakwazi ukuhlanza isici sokuhlunga ngaphakathi ngokubuyisela emuva - igesi izongena ngaphakathi kwesici sokuhlunga ukusuka kumbobo ye-blowback, ifutha impushana endaweni yesihlungi yehle iye embhobhweni.
Sekukonke, izihlungi ezivamile azihlali isikhathi eside ngaphansi kwezimo ezinempushana eningi, futhi izihlungi ze-blowback zinesikhathi eside sempilo futhi kulula ukuzihlanza. Ngakho-ke, nakubaizihlungi ze-blowbackzibiza kakhulu, zibiza kakhulu ngokuhamba kwesikhathi.
