Amagama evacuum aqhelekileyo

Kule veki, ndiqulunqe uluhlu lwamagama aqhelekileyo okucoca ukuququzelela ukuqonda okungcono kwetekhnoloji yevacuum.

1. Isidanga seVacuum

Iqondo lokuncipha kwegesi kwi-vacuum, ngokuqhelekileyo ibonakaliswe "i-vacuum ephezulu" kunye "ne-vacuum ephantsi".Inqanaba levacuum ephezulu lithetha inqanaba levacuum “elungileyo”, inqanaba levacuum elisezantsi lithetha inqanaba levacuum “elibi”.

2. Iyunithi yokufunxa

Ngokuqhelekileyo kusetyenziswa i-Torr (i-Torr) njengeyunithi, kwiminyaka yamuva nje ukusetyenziswa kwamazwe ngamazwe kwe-Pa (Pa) njengeyunithi.

1 Torr = 1/760 atm = 1 mmHg 1 Torr = 133.322 Pa okanye 1 Pa = 7.5×10^-3Torr.

3. Kuthetha umgama okhululekileyo

Umgama ophakathi ohanjwe ngongquzulwano kabini olulandelelanayo lwesuntswana legesi kwintshukumo engaqhelekanga yobushushu, ebonakaliswa luphawu “λ”

4. Isitshixo sokugqibela

Emva kokuba umkhumbi we-vacuum uphonswe ngokupheleleyo, uzinzile kwinqanaba elithile le-vacuum, elibizwa ngokuba yi-vacuum yokugqibela.Ngokuqhelekileyo umkhumbi we-vacuum kufuneka uhlanjululwe kwiiyure ze-12, emva koko uphonswe iiyure ze-12, iyure yokugqibela ilinganiswa yonke imizuzu eyi-10, kwaye ixabiso eliqhelekileyo lamaxesha e-10 lilona xabiso lokugqibela.

5. Izinga lokuhamba

Ubungakanani begesi equkuqelayo kwicandelo elingenasizathu kwiyunithi yexesha, efanekiselwa ngu "Q", kwi-Pa-L/s (Pa-L/s) ​​okanye iTorr-L/s (Torr-L/s).

6, Ukuqhuba kokuhamba

Ibonisa umthamo wombhobho wokufunxa ukudlula igesi.Iyunithi iilitha ngesekhondi (L/s).Kwimeko ezinzileyo, ukuqhutyelwa kombhobho kufana nokuhamba kombhobho ohlulwe ngokuhlukana koxinzelelo phakathi kweziphelo ezimbini zombhobho.Isimboli yale nto ngu-“U”.

U = Q/(P2- P1)

7. Izinga lokumpompa

Kuxinzelelo oluthile kunye nobushushu obuthile, irhasi empompelwe kude kwi-inlet yempompo kwiyunithi yexesha ibizwa ngokuba yisantya sokumpompa, okanye isantya sokumpompa.Oko kukuthi, Sp = Q / (P – P0)

8. Ukubuya kwesantya sokuhamba

Xa umpompo usebenza ngokweemeko ezichaziweyo, ukuhamba kobuninzi bempompo yamanzi kwindawo yeyunithi ye-inlet kunye nexesha leyunithi kwicala elichaseneyo lokupompa, iyunithi yayo yi-g / (cm2-s).

9. Umgibe opholileyo

Isixhobo esibekwe phakathi kwenqanawa yokufunxa kunye nempompo yerhasi ye-adsorbing okanye ukubambisa umphunga weoyile.

I-10, ivalve yegesi ye-ballast

Kuvulwe umngxuma omncinci kwigumbi lokucinezela lempompo ye-oyile etywiniweyo yokucoca i-oyile kunye nevalve yokulawula ifakiwe.Xa i-valve ivuliwe kwaye i-air intake ihlengahlengiswa, i-rotor ijika kwindawo ethile kwaye umoya uxutywe kwigumbi lokunyathela kulo mngxuma ukuze kuncitshiswe umlinganiselo wokunyanzeliswa ukwenzela ukuba uninzi lomphunga lungabikho kwaye igesi ixutywe. ikhutshiwe kwimpompo kunye.

11, Vacuum Umkhenkce Wokomisa

Ukomisa umkhenkce ngevacuum, okwakwaziwa njengokomisa i-sublimation.Umgaqo wayo kukukhenkceza izinto eziphathekayo ukuze amanzi aqulethwe kuwo ajike abe ngumkhenkce, aze enze i-ice sublimate phantsi kwe-vacuum ukufezekisa injongo yokomisa.

12. Ukomisa ngevacuum

Indlela yokomisa iimpahla ngokusebenzisa iimpawu zeqondo eliphantsi lokubilisa kwindawo yokucoca.

I-13, i-Vacuum Vapor Deposition

Kwimo engqongileyo yokufutha, imathiriyeli iyafudunyezwa kwaye ifakwe kwi-substrate ebizwa ngokuba yi-vacuum vapor deposition, okanye i-vacuum coating.

14. Izinga lokuvuza

Ubunzima okanye inani leemolekyuli zezinto eziqukuqela kumngxuma ovuzayo ngeyunithi nganye yexesha.Iyunithi yethu yomthetho yomlinganiselo wokuvuza yiPa·m³/s.

15. Imvelaphi

Inqanaba elizinzile ngakumbi okanye ubungakanani bemitha yemitha okanye isandi esidalwe yindawo ekuyo.
