Common vacuum mazwi

Vhiki rino, ndakanyora runyoro rwemamwe mazwi akajairwa vacuum kuti afambise kunzwisisa kuri nani kwevacuum tekinoroji.

1, Vacuum degree

Chiyero chekuonda kwegasi mumhepo, kazhinji inoratidzwa ne "high vacuum" uye "low vacuum".High vacuum level inoreva "yakanaka" vacuum level, yakaderera vacuum level zvinoreva "varombo" vacuum level.

2. Vacuum unit

Inowanzo shandisa Torr (Torr) seyuniti, mumakore achangopfuura kushandiswa kwepasi rose kwePa (Pa) sechikamu.

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

3. Zvinoreva kureba

Avhareji yenhambwe inofambwa nekudhumhana kuviri kwakatevedzana kwegasi mukufamba kusingaenzaniswi kwekupisa, kunoratidzwa nechiratidzo "λ"

4、 Yekupedzisira vacuum

Mushure mekunge mudziyo wevacuum wanyatsoputirwa, unogadziriswa pane imwe nhanho yevacuum, iyo inonzi yekupedzisira vacuum.Kazhinji mudziyo wevacuum unofanirwa kunatswa kwemaawa gumi nemaviri, wozopombwa kwemaawa gumi nemaviri, awa yekupedzisira inoyerwa maminetsi ega ega gumi, uye avhareji kukosha kwekagumi ndiyo yekupedzisira vacuum kukosha.

5. Flow rate

Huwandu hwegasi hunoyerera nepachikamu chenguva, chinofananidzirwa ne "Q", muPa-L/s (Pa-L/s) ​​kana Torr-L/s (Torr-L/s).

6, Kuyerera kwemaitiro

Inoratidza kugona kwepombi yevacuum kupfuudza gasi.Iyo unit imarita pasekondi (L/s).Mumamiriro akadzikama, kuyerera kwepombi kwakaenzana nekuyerera kwepombi yakakamurwa nemusiyano wekumanikidza pakati pemigumo miviri yepombi.Chiratidzo cheizvi ndi "U".

U = Q/(P2- P1)

7. Kupomba mwero

Pane imwe dzvinyiriro uye tembiricha, gasi rinopomba kubva papiko yepombi muchikamu chenguva inonzi mwero wekupomba, kana kumhanya kwepombi.Kureva, Sp = Q / (P - P0)

8, Dzorera kuyerera kwehuwandu

Kana pombi ichishanda zvinoenderana nemamiriro akatarwa, kuwanda kwekuyerera kwepombi yemvura kuburikidza nepombi inlet unit area uye unit time iri mhiri kwekupomba, unit yayo ig/(cm2-s).

9, Musungo unotonhora (mvura-yakatonhorera baffle)

Mudziyo wakaiswa pakati pemudziyo wekutsvaira nepombi yekutepfenyura gasi kana kuteya mweya wemafuta.

10、Gasi ballast vharafu

Gomba diki rinovhurwa mukamuri yekumanikidza yeoiri-yakavharwa mechanical vacuum pombi uye vharafu inogadzirisa inoiswa.Kana vharuvhu ichivhurwa uye kupinza kwemhepo kuchigadziriswa, rotor inotendeukira kune imwe nzvimbo uye mhepo inosanganiswa mukamuri yekumanikidza kuburikidza negomba iri kuti kuderedze chiyero chekumanikidza kuitira kuti yakawanda yemhepo isaite uye gasi rakasanganiswa mukati. inobviswa papombi pamwe chete.

11、Vacuum Freeze Drying

Vacuum freeze drying, inozivikanwawo se sublimation drying.Nheyo yayo ndeyekuomesa zvinhu kuitira kuti mvura irimo ishanduke kuita ice, uye wobva waita kuti ice sublimate pasi pevacuum kuti iwane kuomesa chinangwa.

12, Vacuum kuomesa

Nzira yekuomesa zvinhu nekushandisa hunhu hwenzvimbo yakaderera yekubikira munzvimbo yevacuum.

13, Vacuum Vapor Deposition

Munzvimbo yevacuum, zvinhu zvinodziiswa uye zvakaputirwa pane substrate inonzi vacuum vapor deposition, kana vacuum coating.

14. Leakage rate

Huremu kana huwandu hwemamorekuru echinhu chinoyerera nepaburi rinobvinza pachikamu chenguva.Yedu yemutemo chikamu cheyero yekuvuza iPa·m³/s.

15. Background

Chiyero chakagadzikana kana huwandu hwemwaranzi kana ruzha rwakagadzirwa nenharaunda yairi.

[Chirevo cheCopyright]: Zviri muchinyorwa zvinobva kunetiweki, kodzero yacho ndeyemunyori wekutanga, kana paine chero kukanganisa, ndapota taura nesu kuti tibvise.
