Pụtara nke mgbapụta agụụ

A na-akpọkwa ịnweta oghere dị ka "vacuum pumping", nke na-ezo aka n'iji nfuli ikuku dị iche iche wepụ ikuku dị n'ime akpa ahụ, nke mere na nrụgide dị n'ime oghere na-adaba n'okpuru otu ikuku. Ka ọ dị ugbu a, iji nweta oghere na ngwaọrụ ndị a na-ejikarị gụnyere rotary vane mechanical vacuum nfuli, mgbọrọgwụ nfuli, mmanụ mgbasa nfuli, mejupụtara molekul nfuli, molecular sieve adsorption nfuli, titanium sublimation nfuli, sputtering ion nfuli na cryogenic nfuli na na. N'ime nfuli ndị a, a na-ekewa nfuli anọ nke mbụ dị ka nfuli nnyefe gas (mkpụrụ ọkụ na-enyefe), nke pụtara na a na-agbanye mkpụrụ ndụ gas na-aga n'ihu n'ime mgbapụta mgbapụta ma na-ahapụ ya na gburugburu ebe obibi iji ghọta ọpụpụ; A na-ekewa nfuli anọ ikpeazụ dị ka nfuli mgbapụta gas (jide vacuum pumps), nke a na-ejikọta ya na molecularly condensed ma ọ bụ kemịkalụ jikọtara na mgbidi dị n'ime nke ụlọ mgbapụta iji nweta oghere achọrọ. A na-akpọkwa nfuli mgbapụta gas na-enweghị mmanụ nfuli n'ihi na ha anaghị eji mmanụ dị ka ihe na-arụ ọrụ. N'adịghị ka nfuli mbufe, nke na-ewepụ gas na-adịgide adịgide, ụfọdụ nfuli mgbapụta na-agbanwe agbanwe, na-ekwe ka gas anakọtara ma ọ bụ condensed na-ahapụ azụ n'ime usoro n'oge usoro ikpo ọkụ.
A na-ekewa nfuli mgbapụta ohere ụzọ abụọ: volumetric na nnyefe ọkụ. Igwe nfuli mbufe volumetric na-agụnyekarị nfuli igwe rotary vane, nfuli mgbanaka mmiri mmiri, nfuli na-emegharị ihe na nfuli mgbọrọgwụ; Nfuli nfuli mbufe ọkụ na-agụnyekarị nfuli molekụla, nfuli jet, nfuli mgbasa mmanụ. Nfuli mgbapụta agụụ na-agụnyekarị mgbasa ozi na-ekpo ọkụ na nfuli ion na-agbapụta.
N'ozuzu, usoro mkpuchi ahụ dị iche iche, oghere mkpuchi mkpuchi ụlọ kwesịrị iru ọkwa dị iche iche, na na nkà na ụzụ na-adịghị ahụkebe, karịa na oghere ndabere (nke a makwaara dị ka intrinsic vacuum) iji gosipụta ọkwa ya. Oghere dị n'azụ na-ezo aka na oghere nke oghere mkpuchi oghere site na mgbapụta agụụ iji gboo mkpa nke usoro mkpuchi nke oghere kachasị elu, na nha nke oghere a, na-adabere na ikike mgbapụta agụụ. Ime ụlọ mkpuchi oghere site na sistemu agụụ ya nwere ike iru oghere kachasị elu nke a na-akpọ oke oghere (ma ọ bụ oke nrụgide). Tebụl 1-2 na-edepụta oke nrụgide na-arụ ọrụ nke ụfọdụ nfuli ikuku nkịtị na nrụgide kacha nke enwere ike nweta. Akụkụ ndị nwere ndò nke tebụl na-anọchi anya nrụgide ndị nwere ike ịnweta site na mgbapụta mgbapụta ọ bụla mgbe ejiri ya na ngwa ndị ọzọ.
