Umsebenzi wepompo ye-vacuum yezimoto ukukhiqiza ingcindezi engalungile futhi ngaleyo ndlela kwandise amandla okubhuleka.Ezimotweni ezishayelwa izinjini ze-diesel, ipompo ye-vacuum ifakwa ukuze inikeze umthombo we-vacuum, njengoba injini ine-CI yokushisa yokucindezela, ukuze izinga elifanayo lokucindezela kwe-vacuum lingakwazi ukuhlinzekwa ekusetshenzisweni okuningi.
Umgomo wokusebenza kwephampu ye-automotive vacuum, okokuqala ezimotweni ezifakwe izinjini zikaphethiloli, ukuthi injini ngokuvamile iwuhlobo lokuthungela, ukuze kukhiqizwe umfutho we-vacuum ophakeme kakhulu egatsheni elithathayo.Lokhu kunganikeza umthombo owanele we-vacuum wesistimu yokubhuleka amandla, kodwa ezimotweni eziqhutshwa yinjini ye-diesel, ngoba injini yayo isebenzisa ukuthungela kokucindezela, ngakho-ke egatsheni lokungena alikwazi ukunikeza izinga elifanayo lokucindezela kwe-vacuum, okudinga ukusetshenziswa Iphampu ye-vacuum inganikeza umthombo we-vacuum, ngaphezu kwalokho kunezimoto ukuze kuhlangatshezwane nokukhishwa kwezimoto ezithile kanye nezidingo zemvelo futhi eklanywe ngaphandle kwenjini Injini iphinde idingeke ukuthi inikeze umthombo owanele we-vacuum ukuze kuqinisekiswe ukuthi imoto ikwazi ukusebenza kahle.
Ukukhishwa kwepompo ye-vacuum ngokuyinhloko ingcindezi ekhiqizwa isistimu ye-servo yamandla, kodwa uma ingasebenzi kahle, isengaqhutshwa amandla omuntu ohlelweni lwe-hydraulic, ukuze idlale indima ku-booster.Isistimu ye-vacuum braking nayo ingabizwa ngokuthi i-vacuum servo system.Isistimu ye-braking yezimoto evamile, ngokuvamile incike kumfutho we-hydraulic njengendlela yokudlulisa, bese iqhathaniswa nesistimu ye-pneumatic braking enganikeza amandla, kuyadingeka ukunikeza uhlelo lokumelana ukuze lunikeze usizo ekubhulekini komshayeli.
Iphampu yevacuum isebenzisa ivacuum ekhiqizwa injini uma isebenza ukuze inikeze umshayeli usizo olwanele lapho efaka amabhuleki, ukuze umshayeli akwazi ukubopha amabhuleki kancane futhi ngokushesha, kodwa uma i-vacuum futha yonakele, ishoda okuthile. inani losizo, ngakho lapho ufaka amabhuleki uzozizwa unzima, futhi umphumela wamabhuleki uzoncipha, futhi ngezinye izikhathi uzohluleka, okusho ukuthi Lokhu kusho ukuthi ipompo ye-vacuum ilimele.
