Ukuhlunga okuphelele nokuhlunga okuhlobene

Ekukhetheni isici sendlu/yesihlungi, Akwanele uma kuphela ucabangela isilinganiso sokuhlunga kanye nosayizi wezindlu zokuhlunga , kodwa futhi kudingeka ucabangele ukusebenza kahle kwesihlungi .

1.Isilinganiso esincane :

Ngaphambilini, ukulinganisa kwamagama kwakusetshenziselwa ukuchaza ukunemba kokuhlunga kwesihlungi.

Kodwa-ke, ukulinganisa okulinganiselwe kunevelu eyireferensi encane ekusetshenzisweni okungokoqobo.Ukuhlolwa kubonisa ukuthi izinhlayiya zokungcola ezinobubanzi obungu-200um zingaphinda zidlule kusici sokuhlunga ngesilinganiso esilinganiselwe esingu-10um kwezinye izimo. Ngakho-ke, inani lesilinganiso sesihlungi se-norminol kwakungahloselwe ukuba kube okomfanekiso, ngakho sekuqediwe manje

2.Isilinganiso esiphelele :

Isilinganiso Esiphelele futhi siyinkomba evamile yokucaciswa kokunemba kwesihlungiIsilinganiso esiphelele sisho ukuthi ubukhulu bezinhlayiyana ububanzi obungadlula kusihlungi, Ngama-microns, lowo usayizi omkhulu wembotshana yesihlungi, uma I-particle inkulu kunalo sayizi wembotshana, ayikwazi ukudlula kusici sokuhlunga, ngakho-ke iyahlungwa ukuze ikhishwe.Isilinganiso esiphelele sinembe kakhulu kunokulinganisa okusesilinganisweni futhi sibonisa kangcono ubuncane bezinhlayiyana ezinganqanyulwa isihlungi，Kodwa izinhlayiya azizona zonke eziyindilinga.Zinesimo esingavamile，Ngaphezu kwalokho, imbobo yokuhlunga yesici sokuhlunga ingase ingalingani ngenxa yenqubo yokucubungulaNgakho-ke kusengaba nezinhlanzi ezinosayizi omkhulu eziphunyuka ngenetha.Ngakho-ke, kunegebe elithile phakathi kokulinganisa okuphelele nokusebenzisa okungokoqobo

3.Isilinganiso se-Beta:

Okwamanje, inkomba evame kakhulu yokuhlunga ngokunemba nokusebenza ngempumelelo Isilinganiselwa se-Beta (inani le-Beta).Isilinganiso se-Beta isilinganiso sokuhlunga, okuyisilinganiso senani lezinhlayiya ezithile zosayizi wezimbotshana eziqukethwe oketshezini olusenhla nomfula. wesici sokuhlunga, Lapho uthola umphumela wokuhlunga wesici sokuhlunga.Okokuqala, inombolo nosayizi wezinhlayiya zokungcola zosayizi othile kuvolumu yeyunithi kuwoyela okhuphuka nomfula wesici sokuhlunga kutholwa ithuluzi lokulinganisa izinhlayiyana.Bese, inombolo nevolumu yezinhlayiya kuwoyela ongezansi wesici sokuhlunga kuyalinganiswa.Khona-ke, inani lokukhuphuka komfula lihlukaniswa ngenani lokuwela phansi, futhi isilinganiso esitholiwe yi-filtration ratio

Isibonelo, lapho kutholwa ingxenye engenhla yomfula, inani lezinhlayiya ezinosayizi omkhulu kuno-5 microns ngu-10. Ngemva kokuhlunga ngento yesihlungi, inani lezinhlayiya ezingaphezu kwama-microns angu-5 zikalwa ezansi nomfula ngu-1, bese kuba isihlobo. ezingeni lokunemba lama-microns angu-5, isilinganiso sokuhlunga sesici sokuhlunga singu-10/1=10, esimakwe ngokuthi β5 =10. Ngokusobala, uma likhulu inani lika-β, kuba ngcono umphumela wokuhlunga.Lapho ukhetha isici sokuhlunga, ngaphezu kwalokho. ekunembeni kokuhlunga, kodwa nokubona isilinganiso sokuhlunga.Ukuthatha izinhlayiya ezincane ze-micron ezingu-5 njengesibonelo, uma izinhlayiya ezikalwa phezulu komfula ziyisigidi esingu-1/mL, inani elihambisanayo lomfula kanye nokuhlunga kuboniswa kuthebula elilandelayo:

Uma ukuphumelela kwesihlungi sesici sokuhlunga simelelwa ngamaphesenti, ifomula yokuguqula ithi ((β-1)/ β-value) x 100. Ngokwesibonelo, kuthebula elingenhla, inani lika-β lingu-20, kanye nephesenti lokuguqulwa. of the ukusebenza kahle isihlungi kuyinto201)/ 20=19/20=0.95,0.95*100=95%

Ngakho-ke, kusici sokuhlunga esinokunemba kokuhlunga kwama-microns angu-5, uma inani lika-β lingu-10, iphesenti lokuhlunga lingu-90%, futhi ngokungcola okuyizinhlayiyana ezinosayizi omkhulu noma olingana nama-microns angu-5, u-90% ungahlungwa. kubalulekile ukuqaphela ukuthi nakuba i-beta ingasisiza ukuba siqonde umphumela wokuhlunga, inenani lereferensi, kodwa i-beta ibonisa ukusebenza kahle kokuhlunga kungase kuhluke kancane ngokushintsha kokugeleza nezinga lokushisa, ukukhethwa kwemishini yokuhlunga, kufanele inake. ekusetshenzisweni kwezinga lokushisa, izinga lokugeleza langempela, izinto ezibonakalayo umphumela wokuhlunga we-viscosity nezimo ezihlobene

Ukwengeza, inani elingu-β alikwazi ukuchaza umthamo wokuphatha wesihlungi, esisetshenziswayo, uma umthamo wokuthwala ukungcola umncane, futhi ukungcola kokubalulekile kusinda kakhulu, isici sokuhlunga sizovinjwa maduzane, ngaleyo ndlela kuthinte umphumela wokusetshenziswa.Ngakho-ke, ngakho-ke lapho uthenga, kufanele futhi ukwazi ukuthwala ukungcolaumthamo wesici sokuhlunga
