Imigomo ye-vacuum evamile

Kuleli sonto, ngihlanganise uhlu lwamagama athile ajwayelekile e-vacuum ukuze kube lula ukuqonda kangcono ubuchwepheshe be-vacuum.

1. I-vacuum degree

Izinga lobuncane begesi ku-vacuum, ngokuvamile ivezwa "i-vacuum ephezulu" kanye "ne-vacuum ephansi".Izinga eliphezulu levacuum lisho izinga “elihle” levacuum, izinga eliphansi levacuum lisho izinga “elibi” levacuum.

2. Iyunithi yeVacuum

Ivamise ukusebenzisa i-Torr (Torr) njengeyunithi, eminyakeni yamuva nje ukusetshenziswa komhlaba wonke kwe-Pa (Pa) njengeyunithi.

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

3. Kusho ibanga lamahhala

Ibanga elimaphakathi elihanjwe ngokushayisana okubili okulandelanayo kwezinhlayiya zegesi ekuhambeni okungajwayelekile kokushisa, okuvezwa uphawu elithi “λ”

4. Ivacuum yokugcina

Ngemva kokuba umkhumbi we-vacuum uphonswe ngokugcwele, uzinza ezingeni elithile le-vacuum, elibizwa ngokuthi i-vacuum yokugcina.Ngokuvamile umkhumbi we-vacuum kufanele ucwengwe amahora angu-12, bese uphonswa amahora angu-12, ihora lokugcina likalwa njalo ngemizuzu eyi-10, futhi inani elilinganiselwe lezikhathi ezingu-10 yinani lokugcina le-vacuum.

5. Izinga lokugeleza

Inani legesi eligeleza esigabeni esingafuneki ngeyunithi ngayinye yesikhathi, efanekiselwa ngokuthi “Q”, nge-Pa-L/s (Pa-L/s) ​​noma i-Torr-L/s (Torr-L/s).

6, Ukugeleza kokuziphatha

Ibonisa umthamo wepayipi levacuum ukudlulisa igesi.Iyunithi ingamalitha ngomzuzwana (L/s).Esimeni esingaguquki, ukugeleza kwepayipi kufana nokugeleza kwepayipi ehlukaniswe umehluko wokucindezela phakathi kweziphetho ezimbili zepayipi.Uphawu lwalokhu ngu-“U”.

U = Q/(P2- P1)

7. Izinga lokupompa

Ngokucindezela okuthile namazinga okushisa, igesi empontshelwa kude nendawo yokumpompa ngeyunithi yesikhathi ibizwa ngokuthi izinga lokumpompa, noma isivinini sokumpompa.Okungukuthi, Sp = Q / (P – P0)

8. Buyisela izinga lokugeleza

Lapho iphampu isebenza ngokwezimo ezishiwo, ukugeleza kwenqwaba yoketshezi lwepompo endaweni yeyunithi yokungena kwepompo kanye nesikhathi seyunithi ngakolunye uhlangothi lokumpompa, iyunithi yalo ngu-g/(cm2-s).

9. Isicupho esibandayo (i-baffle epholile ngamanzi)

Idivayisi ebekwe phakathi komkhumbi wevacuum kanye nephampu yegesi ekhangisayo noma yokubamba umhwamuko kawoyela.

I-10, i-valve ye-ballast yegesi

Imbobo encane ivulwa ekamelweni lokucindezelwa lephampu ye-vacuum yomshini evalwe ngamafutha futhi i-valve yokulawula ifakiwe.Lapho i-valve ivuliwe futhi kulungiswa ukungena komoya, i-rotor iphendukela endaweni ethile futhi umoya uxutshwe ekamelweni lokucindezela ngale mbobo ukuze kuncishiswe isilinganiso sokucindezela ukuze iningi le-steam lingafinyeleli futhi igesi ixubene. ikhishiwe empompini ndawonye.

11, I-Vacuum Freeze Drying

I-vacuum frize drying, eyaziwa nangokuthi ukomisa i-sublimation.Umgomo wawo uwukuqandisa impahla ukuze amanzi aqukethwe kuwo aphenduke iqhwa, bese wenza i-ice sublimate ngaphansi kwe-vacuum ukufeza injongo yokomisa.

12. Ukomisa nge-vacuum

Indlela yokomisa impahla ngokusebenzisa izici zendawo yokubilisa ephansi endaweni ye-vacuum.

13. I-Vacuum Vapor Deposition

Endaweni ye-vacuum, okokusebenza kuyashisiswa futhi kufakwe endaweni engaphansi ebizwa ngokuthi i-vacuum vapor deposition, noma i-vacuum coating.

14. Izinga lokuvuza

Isisindo noma inombolo yama-molecule ento egeleza embotsheni evuzayo ngeyunithi ngayinye yesikhathi.Iyunithi yethu esemthethweni yesilinganiso sokuvuza yi-Pa·m³/s.

15. Isendlalelo

Izinga elizinzile noma inani lemisebe noma umsindo odalwe indawo etholakala kuyo.
