Ukuthola i-vacuum kubuye kwaziwe ngokuthi “i-vacuum pumping”, okubhekisela ekusetshenzisweni kwamaphampu e-vacuum ahlukene ukuze kukhishwe umoya ongaphakathi kwesitsha, ukuze umfutho ongaphakathi esikhaleni wehle ube ngaphansi komkhathi owodwa. Okwamanje, ukuze kutholwe i-vacuum kanye namadivayisi asetshenziswa kakhulu ahlanganisa amaphampu e-vacuum emishini kagesi ejikelezayo, amaphampu ezimpande, amaphampu okusabalalisa uwoyela, amaphampu amangqamuzana ayinhlanganisela, amaphampu e-molecular sieve adsorption, amaphampu e-titanium sublimation, amaphampu e-ion afafazayo namaphampu e-cryogenic nokunye. Kulawa maphampu, amaphampu amane okuqala ahlukaniswa njengamaphampu okudlulisa igesi (amaphampu e-vacuum yokudlulisa), okusho ukuthi ama-molecule egesi adonswa ngokuqhubekayo kupompo ye-vacuum futhi akhishelwe endaweni yangaphandle ukuze abone ukuphuma; amaphampu amane okugcina ahlukaniswa njengamaphampu abamba igesi (amaphampu e-vacuum capture), ahlanganiswe nge-molecularly noma ahlanganiswe ngamakhemikhali odongeni lwangaphakathi lwegumbi lokumpompa ukuze athole i-vacuum edingekayo. Amaphampu athatha igesi abizwa nangokuthi amaphampu evacuum angenawo uwoyela ngoba awasebenzisi uwoyela njengendawo yokusebenza. Ngokungafani namaphampu okudlulisa, asusa igesi unomphela, amanye amaphampu abamba ayahlehliseka, okuvumela igesi eqoqiwe noma ejiyile ukuthi ikhishwe ibuyiselwe ohlelweni ngesikhathi senqubo yokushisisa.
Amaphampu e-vacuum yokudlulisa ahlukaniswe izigaba ezimbili eziyinhloko: i-volumetric kanye nokudlulisa umfutho. Amaphampu okudlulisa ivolumu ngokuvamile ahlanganisa amaphampu emishini ye-rotary vane, amaphampu ayindandatho awuketshezi, amaphampu aphindaphindayo kanye namaphampu e-Roots; amaphampu evacuum okudlulisa umfutho ngokuvamile ahlanganisa amaphampu amangqamuzana, amaphampu ejethi, amaphampu okusabalalisa uwoyela. Amaphampu we-vacuum wokuthwebula ngokuvamile ahlanganisa i-adsorption enethempelesha ephansi kanye namaphampu e-sputtering ion.
Ngokuvamile, inqubo yokumboza ihlukile, i-vacuum yegumbi lokunamathisela kufanele ifinyelele emazingeni ahlukene, futhi kubuchwepheshe be-vacuum, ngaphezulu kwe-vacuum yangemuva (eyaziwa nangokuthi i-intrinsic vacuum) ukuveza izinga layo. I-vacuum yangemuva isho ivacuum yegumbi lokuvalelisa ngepompo yevacuum ukuze kuhlangatshezwane nezidingo zenqubo yokumboza ye-vacuum ephakeme kakhulu, kanye nosayizi walesi sikhala, ngokuyinhloko kuncike kumthamo wokumpompa kwe-vacuum. Igumbi lokuhlanganisa nge-vacuum system vacuum lingafinyelela endaweni ephakeme kakhulu ebizwa ngokuthi i-limit vacuum (noma ingcindezi yokunciphisa). Ithebula 1-2 libala ingcindezi yokusebenza kwamaphampu evacuum avamile kanye nengcindezi yokugcina engatholwa. Izingxenye zethebula ezinomthunzi zimelela izingcindezi ezingatholwa yiphampu ye-vacuum ngayinye uma isetshenziswa ngokuhambisana nezinye izinto zokusebenza.
