Mawu a vacuum wamba

Sabata ino, ndalemba mndandanda wa mawu omwe amagwiritsidwa ntchito ngati vacuum kuti mumvetsetse bwino zaukadaulo wa vacuum.

1. Digiri ya vacuum

Mlingo wa kuonda kwa gasi mu vacuum, nthawi zambiri amawonetsedwa ndi "vacuum yapamwamba" ndi "vacuum yochepa".Mulingo wa vacuum wapamwamba umatanthauza mulingo wa vacuum "wabwino", mulingo wocheperako umatanthauza "kusauka" kwa vacuum.

2, Vacuum unit

Nthawi zambiri amagwiritsa ntchito Torr (Torr) ngati gawo, m'zaka zaposachedwa kugwiritsidwa ntchito kwapadziko lonse kwa Pa (Pa) ngati gawo.

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

3. Kutanthauza mtunda waulere

Mtunda wapakati woyenda ndi kugunda kuwiri kotsatizana kwa tinthu ta gasi pakuyenda kosakhazikika, komwe kumawonetsedwa ndi chizindikiro "λ"

4, Vuto lomaliza

Chotengeracho chikaponyedwa mokwanira, chimakhazikika pamlingo wina wa vacuum, womwe umatchedwa vacuum yomaliza.Kawirikawiri chotengera cha vacuum chiyenera kuyengedwa kwa maola 12, kenako kupopera kwa maola 12, ola lomaliza limayesedwa mphindi 10 zilizonse, ndipo mtengo wapakati wa nthawi 10 ndiye mtengo wotsiriza wa vacuum.

5. Mtengo woyenda

Kuchuluka kwa mpweya womwe ukuyenda mu gawo losagwirizana pa nthawi, yophiphiritsira "Q", mu Pa-L/s (Pa-L/s) ​​kapena Torr-L/s (Torr-L/s).

6, Mayendedwe oyenda

Imawonetsa mphamvu ya chitoliro cha vacuum podutsa gasi.Chigawo ndi malita pa sekondi (L/s).M'malo okhazikika, kayendedwe ka kayendedwe ka chitoliro ndi kofanana ndi kutuluka kwa chitoliro kugawidwa ndi kusiyana kwa kuthamanga pakati pa malekezero awiri a chitoliro.Chizindikiro cha izi ndi "U".

U = Q/(P2- P1)

7. Kupopera mlingo

Pakuthamanga kwina ndi kutentha, mpweya woponyedwa kutali ndi polowera pampu mu nthawi yotchedwa kupopa, kapena kuthamanga kwa kupopa.Ndiko kuti, Sp = Q / (P - P0)

8, Bweretsani otaya mlingo

Pampu imagwira ntchito molingana ndi zomwe zafotokozedwera, kuchuluka kwa madzi a pampu kupyola pagawo lolowera pampu ndi nthawi yagawo mbali ina ya kupopera, gawo lake ndi g/(cm2-s).

9, Msampha wozizira (mwazi wokhazikika)

Chipangizo chomwe chimayikidwa pakati pa chotengera cha vacuum ndi mpope cholumikizira gasi kapena kukopera mpweya wamafuta.

10, valavu yamagetsi yamagetsi

Bowo laling'ono limatsegulidwa m'chipinda chopondera cha pampu yamagetsi yotsekedwa ndi mafuta ndipo valavu yowongolera imayikidwa.Vavu ikatsegulidwa ndikusinthidwa kwa mpweya, rotor imatembenukira kumalo ena ake ndipo mpweya umasakanizidwa mu chipinda choponderezedwa kudzera mu dzenje ili kuti muchepetse chiŵerengero cha kuponderezana kotero kuti nthunzi yambiri isagwedezeke ndi mpweya wosakanikirana. imachotsedwa pampope pamodzi.

11, Vacuum Freeze Kuyanika

Vacuum amaundana kuyanika, komwe kumadziwikanso kuti sublimation kuyanika.Mfundo yake ndikuyimitsa zinthuzo kuti madzi omwe ali mmenemo asanduke madzi oundana, kenako n’kupanga madzi oundana kuti asasunthike pansi pa vacuum kuti akwaniritse cholinga choyanika.

12, Kuyanika kwa vacuum

Njira yowumitsa katundu pogwiritsa ntchito mawonekedwe a malo owira pang'ono pamalo opanda vacuum.

13, Kuyika kwa Vacuum Vapor

M'malo opanda vacuum, zinthuzo zimatenthedwa ndikuzikutidwa pagawo laling'ono lotchedwa vacuum vapor deposition, kapena zokutira za vacuum.

14. Kutayikira mlingo

Unyinji kapena kuchuluka kwa mamolekyu a chinthu chomwe chimayenda mu dzenje lotayira pa nthawi imodzi.Gawo lathu lovomerezeka la kutayikira ndi Pa·m³/s.

15. Mbiri

Mulingo wokhazikika kwambiri kapena kuchuluka kwa ma radiation kapena mawu opangidwa ndi chilengedwe chomwe chili.
