Ngaphambi kokukhetha into yokuhlunga, kufanele siqale sicacise ukungaqondi kahle okubili:
(1) Ukukhetha into yokuhlunga ngokunemba okuthile (Xμm) kungahluza zonke izinhlayiya ezinkulu kunalokhu kunemba.
Njengamanje, inani elingu-β livamise ukusetshenziswa emazweni ngamazwe ukumela ukusebenza kahle kokuhlunga kwesici sokuhlunga.Okubizwa ngokuthi inani lika-β libhekisela esilinganisweni senani lezinhlayiyana ezinkulu kunosayizi othile oketshezini endaweni yokungena yesici sokuhlunga ukuya enanini lezinhlayiya ezinkulu kunosayizi othile oketshezini ekuphumeni kwesici sokuhlunga. .Ngakho-ke, uma likhulu inani elingu-β, liphakamisa ukusebenza kahle kokuhlunga kwesici sokuhlunga.
Kungabonakala ukuthi noma iyiphi ingxenye yesihlungi iwukulawula ukunemba okuhlobene, hhayi ukulawula ukunemba okuphelele.Isibonelo, ukunemba kokuhlunga kwe-PALL Corporation e-United States kuyalinganiswa uma inani lika-β lilingana no-200. Uma ukhetha isici sokuhlunga, ngaphezu kokunemba kokuhlunga nokusebenza kahle kokuhlunga, inqubo yezinto ezibonakalayo kanye nesakhiwo sesici sokuhlunga kufanele futhi. kucatshangelwe, futhi imikhiqizo enokuwohloka kwengcindezi ephezulu, i-fluidity ephezulu nempilo ende yesevisi kufanele ikhethwe.
(2) Izinga lokugeleza elilinganiselwe (elivamile) lesici sokuhlunga izinga lokugeleza langempela lesistimu.
Eminyakeni yakamuva, idatha yokukhetha ehlinzekwe abakhiqizi besici sokuhlunga akuvamile ukusho ubudlelwano phakathi kwezinga lokugeleza elilinganiselwe le-elementi yesihlungi kanye nezinga lokugeleza langempela lesistimu, okubangela ukuthi umklami wesistimu abe nenkohliso yokuthi izinga lokugeleza elilinganiselwe. sesici sokuhlunga izinga lokugeleza langempela lesistimu ye-hydraulic.Ngokusho kolwazi olufanele, ukugeleza okulinganiselwe kwesici sokuhlunga izinga lokugeleza kwamafutha adlula endaweni yokuhlunga ehlanzekile ngaphansi kokumelana okucacisiwe kwasekuqaleni lapho i-viscosity yamafutha ingu-32mm2 / s.Kodwa-ke, ekusetshenzisweni okusebenzayo, ngenxa yemidiya ehlukene esetshenzisiwe kanye nokushisa kwesistimu, i-viscosity yamafutha izoshintsha nganoma yisiphi isikhathi.Uma into yokuhlunga ikhethwa ngokuya ngokugeleza okulinganiselwe kanye nezinga lokugeleza langempela lika-1: 1, lapho i-viscosity kawoyela wesistimu ikhudlwana kancane, ukumelana kwamafutha adlula isici sokuhlunga kuyanda (isibonelo, i-viscosity ye-viscosity No. 32 uwoyela we-hydraulic ku-0 ° C cishe u-420mm2 / s) , Ngisho nokufinyelela inani lokuvinjelwa kokungcola kwesici sokuhlunga, isici sokuhlunga sibhekwa njengevinjiwe.Okwesibili, isici sokuhlunga sesici sokuhlunga siyingxenye egqokile, engcoliswa kancane kancane ngesikhathi somsebenzi, indawo yokuhlunga ephumelelayo yezinto zokuhlunga iyancipha ngokuqhubekayo, futhi ukumelana kwamafutha adlula endaweni yokuhlunga kufinyelela ngokushesha inani lesignali ye-pollution blocker.Ngale ndlela, isici sokuhlunga sidinga ukuhlanzwa noma ukushintshwa njalo, okwandisa izindleko zokusebenzisa komsebenzisi.Kuzophinde kubangele ukungasebenzi okungadingekile noma kuze kumise ukukhiqiza ngenxa yabasebenzi bokulungisa abadukisayo.
Uma kuphakeme ukunemba kokuhlunga kwesici sokuhlunga se-hydraulic, kungcono?
Umphumela wokuhlunga okunembe kakhulu muhle impela, kodwa lokhu empeleni kuwukungaqondi okukhulu.Ukunemba kwesici sokuhlunga uwoyela we-hydraulic odingwa uhlelo lwe-hydraulic alukho "phezulu" kodwa "lufanelekile".Izinto zokuhlunga uwoyela we-hydraulic ezinembe kakhulu zinekhono eliphansi lokudlula uwoyela (futhi ukunemba kwezinto zokuhlunga uwoyela we-hydraulic afakwe ezindaweni ezihlukene akukwazi ukufana), kanye nezinto zokuhlunga uwoyela we-hydraulic ezinemba okuphezulu nazo cishe zizovinjwa.Eyodwa ubude besikhathi esifushane futhi kufanele ishintshwe njalo.
Izinyathelo zokukhetha isihlungi sikawoyela weHydraulic
Ukukhetha okujwayelekile kunezinyathelo ezilandelayo:
①Thola izingxenye ezizwela kakhulu ukungcola ohlelweni, futhi unqume ukuhlanzeka okudingekayo ohlelweni;
②Nquma indawo yokufaka, ifomu lokuhlunga kanye nebanga lokugeleza kwengcindezi yesici sokuhlunga;
③Ngokuya ngomehluko wengcindezi esethiwe nezinga lokugeleza, bheka ijika lenani elingu-β lezinto ezihlukene zokuhlunga, bese ukhetha okubalulekile kwesici sokuhlunga nobude.Thola ukwehla kokucindezela kwegobolondo kanye nokwehla kokucindezela kwesici sokuhlunga eshadini lesampula, bese ubale umehluko wokucindezela, okungukuthi: △ isici sesihlungi se-p≤△p isilungiselelo sesici sokuhlunga;△p assembly≤△p isilungiselelo somhlangano.Umkhiqizi ngamunye wesici sokuhlunga e-China ubeke izinga lokugeleza elilinganiselwe le-elementi yesihlungi ekhiqizwa yibona.Ngokuvumelana nesipiliyoni esidlule kanye nokusetshenziswa kwamakhasimende amaningi, lapho uwoyela osetshenziswa ohlelweni kuwuwoyela ojwayelekile we-hydraulic, kunconywa ukuthi into yokuhlunga ikhethwe ngokuya ngokuphindaphinda okulandelayo kwesilinganiso sokugeleza.:
a Ukugeleza okulinganiselwe kokuhlunga uwoyela kanye nezihlungi zokubuyisela uwoyela kungaphezu kokuphindwe izikhathi ezi-3 ukugeleza kwangempela kwesistimu;
b Ukugeleza okulinganiselwe kwesici sesihlungi sepayipi kungaphezu kokuphindwe izikhathi ezingu-2.5 ukugeleza kwangempela kwesistimu.Ngaphezu kwalokho, izici ezifana nendawo yokusebenza, impilo yesevisi, imvamisa yokushintshwa kwengxenye, kanye nemidiya yokukhetha isistimu nakho kufanele kucatshangelwe kahle ukuze kufezwe injongo yokuthuthukisa ukukhetha kwesici sokuhlunga.
Izinyathelo zokuphepha zokufakwa kwesici sokuhlunga uwoyela we-hydraulic
Indawo yokufaka kufanele icatshangelwe, nayo eyingxenye ebaluleke kakhulu.Uma ungaqiniseki ukuthi uyifake kuphi, awukwazi ukukhetha isici sokuhlunga uwoyela we-hydraulic.Umsebenzi nokunemba kwesici sokuhlunga uwoyela we-hydraulic ezindaweni ezihlukene nakho kuhlukile.
