Yini eyenza usebenzise amandla amancane kuyo ukuze uphakamise imoto yakho?Yebo, ijekhi engathwalwa nemoto ukwenza imisebenzi eyisisekelo yemishini.Kodwa-ke, ngaphezu kwale jekhi ephathekayo, kunamajekhi ahlukahlukene atholakala emakethe.Amajack angahlukaniswa ngokuya ngomshini wokukhiqiza amandla.Sinojeke abayimishini, ojeke bakagesi, ojeke abadonsa amanzi kanye namajekhi womoya.Zonke lezi zinhlobo zamajack zingakwazi ukuphakamisa izinto ezinzima, kodwa izinkambu zabo zokufaka isicelo, umthamo wokuphakamisa kanye nomklamo zizohluka.

A i-hydraulic jackiyithuluzi eliwumshini elisebenzisa amandla aluketshezi ukuze lisebenze.Ngosizo lwama-jack hydraulic, izinto ezinzima zingaphakanyiswa kalula ngenani elincane lamandla.Ngokuvamile, idivayisi yokuphakamisa isebenzisa amasilinda amanzi ukuze isebenzise amandla okuqala.Ojekhi bamaHydraulic banezinhlobonhlobo zezinhlelo zokusebenza kwezitimela, ezokuvikela, ezokwakha, ezondiza, imishini yokuphatha impahla, izimboni zamandla kagesi ophehlwa ngamanzi, izinkundla zezimayini neziphakamisayo.Ukunyakaza okubushelelezi nokushelelayo kwejekhi yejubane eguquguqukayo ngaphansi kwemithwalo ehlukahlukene noma ephezulu kwenza i-hydraulic jack ifanele zonke izinhlelo zokusebenza ezingenhla.Ngokufanayo, ukusetshenziswa kwama-jack hydraulic kunganikeza umthamo omkhulu wokuphakamisa emabangeni amakhulu.

Uma sibheka emuva emlandweni, ilungelo lobunikazi likajekhi we-hydraulic ophathwayo lanikezwa u-Richard Dudgeon ngo-1851. Ngaphambi kwalokhu, uWilliam Joseph Curtis wafaka isicelo selungelo lobunikazi laseBrithani lojeke we-hydraulic ngo-1838.

Amathangi okugcina uwoyela noma amathangi e-buffer, amasilinda amanzi, amaphampu, ama-valve okuhlola kanye nama-valve okukhulula yizingxenye ezibalulekile zama-jack hydraulic, ezisiza ukuphakamisa izinto ezinzima.Njengazo zonke izinhlelo ze-hydraulic, ithangi lokugcina uwoyela lizogcina uwoyela we-hydraulic futhi lilethe uwoyela we-hydraulic ocindezelwe kusilinda esixhunyiwe ngosizo lwepompo ye-hydraulic.I-valve yokuhlola etholakala phakathi kwe-cylinder nepompo izoqondisa ukugeleza.Uma uketshezi lungena kusilinda esisebenza nge-hydraulic, i-piston iyanwebeka futhi icindezele isilinda se-hydraulic yesibili.Ngemva kokuqeda umsebenzi, i-valve yokukhulula isetshenziselwa ukuhoxisa i-piston ye-hydraulic.Umthamo we-reservoir noma ithangi lebhafa uzoncika esimisweni sikawoyela osebenza ngogesi ukuze isilinda sinwetshwe futhi sihlehle.Imininingwane eminingi ngamajekhi asebenza ngogesi ichazwe ngezansi.

Ngabe ijekhi ye-hydraulic isebenza kanjani?Isimiso sokusebenza sama-jack hydraulic sisekelwe kumgomo we-Pascal pressure.Okusho ukuthi, ingcindezi esetshenziswa oketshezini olugcinwe esitsheni izosatshalaliswa ngokulinganayo kuzo zonke izinkomba.Izingxenye ezibalulekile zejekhi ye-hydraulic yi-hydraulic cylinder, uhlelo lokumpompa kanye nowoyela we-hydraulic (imvamisa uwoyela).Khetha uketshezi lwe-hydraulic jack ngokucabangela izici ezithile zoketshezi (ezifana ne-viscosity, ukuzinza kwe-thermal, ukuhlunga, ukuzinza kwe-hydrolytic, njll.).Uma ukhetha uwoyela we-hydraulic ohambisanayo, uzohlinzeka ngokusebenza okuhle kakhulu, ukuzigcoba ngokwakho nokusebenza okushelelayo.Idizayini ye-hydraulic jack izoba namasilinda amabili (enye encane nenye enkulu) exhunywe kwelinye ngamapayipi.Womabili amasilinda angama-hydraulic agcwaliswe kancane ngamafutha we-hydraulic.Uma ingcindezi encane isetshenziswa kusilinda esincane, ingcindezi izodluliselwa ngokulinganayo kusilinda esikhulu ngoketshezi olungenakucindezelwa.Manje, isilinda esikhulu sizothola umphumela wokuphindaphinda kwamandla.Amandla asetshenziswa kuwo wonke amaphuzu amasilinda amabili azofana.Nokho, amandla akhiqizwa isilinda esikhulu azoba phezulu futhi alingane nendawo engaphezulu.Ngaphezu kwe-cylinder, ujeke we-hydraulic uzofaka nesistimu yokumpompa ukusunduza uketshezi kusilinda ngevalvu yendlela eyodwa.Le valve izokhawulela ukubuya kukawoyela we-hydraulic kusuka kusilinda esisebenza ngehydraulic.

Amabhodlela ojekefuthi ojeke bamapuleti bayizinhlobo ezimbili zamajekhi asebenza ngamanzi.Iphedi yokuthwala esekelwe i-shaft eqondile inesibopho sokulinganisa isisindo sento ephakanyisiwe.Amajack asetshenziselwa ukunakekela izisekelo zemoto nezindlu, kanye namakheshi amafushane aqondile.Amajack angahlinzeka ngebanga elibanzi lokuphakamisa okuqondile.Ngakho-ke, lawa majack asetshenziswa kakhulu embonini yezimayini.Ngokungafani nesiphakamisi sebhodlela, i-shaft evundlile iphusha i-crank ukuze ixhume ku-pad yokuliphakamisa, bese iliphakamisa liqonde phezulu.

Singafinyelela esiphethweni ngemva kokuxoxa ngamasu okuxazulula izinkinga ojekhi abasebenza ngogesi.Yini okufanele ngiyenze uma i-hydraulic jack ingakwazi ukuphakamisa izinto?Izinga eliphansi likawoyela lingase libe yimbangela yaleli phutha.Ngakho-ke, okokuqala, udinga ukuhlola izinga likawoyela.Uma uthola ukuthi inani lamafutha ohlelweni ayanele, sicela ugcwalise amafutha.Ukuvuza noma ukuhluleka kwezivalo kungase kube enye imbangela yalesi simo.Uma i-gasket yonakalisiwe, i-gasket ku-cylinder yokucindezela idinga ukushintshwa.
