UmGaqo wokuSebenza wePompu yeVacuum yeengcambu

Impompo vacuum yeengcambuibhekisa kwimpompo yokufunxa umthamo oguquguqukayo exhotyiswe ngeerotha ezimbini ezimile okwencakuba ezijikeleza ngolungelelwano kumacala achaseneyo. Kukho i-gap encinci phakathi kwee-rotors kunye phakathi kwee-rotors kunye nodonga lwangaphakathi lwe-casing yempompo ngaphandle kokunxibelelana. I-gap ngokubanzi i-0.1 ukuya kwi-0.8 mm; Akukho lubrication yeoli efunekayo. Iiprofayili ze-rotor ziquka imigca ye-arc, imigca ye-involute, kunye ne-cycloids. Umthamo wokusetyenziswa kwempompo ye-involute rotor iphezulu kwaye ukuchaneka kwe-machining kulula ukuqinisekisa, ngoko ke iphrofayili ye-rotor ininzi yohlobo lwe-involute.

Umgaqo wokusebenza we-aImpompo vacuum yeengcambuiyafana naleyo yeRoots blower. Ngenxa yokujikeleza okuqhubekayo kwe-rotor, i-gas ephothiweyo ifakwe kwisithuba v0 phakathi kwe-rotor kunye negobolondo yempompo evela kwi-air inlet, kwaye emva koko ikhutshwe kwi-port yokukhupha. Ekubeni indawo ye-v0 ivalwe ngokupheleleyo emva kokuphefumla, akukho ukunyanzeliswa okanye ukwandiswa kwegesi kwigumbi lokupompoza. Kodwa xa umphezulu we-rotor ujikeleza kumda we-exhaust port kwaye indawo ye-v0 idityaniswe kwicala lokukhupha, ngenxa yoxinzelelo oluphezulu lwegesi kwicala lokukhupha, enye igesi ibaleka ibuyele kwisithuba v0, ibangela ukuba uxinzelelo lwegesi ukunyuka ngokukhawuleza. Njengoko i-rotor iqhubeka ijikeleza, igesi ikhutshwa kwimpompo.
