Yintoni ekwenza ukuba usebenzise amandla amancinci kuyo ukunyusa imoto yakho?Ewe, yijekhi enokuthi ithwalwe kunye nemoto ukwenza imisebenzi esisiseko yoomatshini.Nangona kunjalo, ukongeza kule jack ephathekayo, kukho iijack ezahlukeneyo ezikhoyo kwimarike.IiJacks zinokuhlelwa ngokwendlela yokuvelisa amandla.Sineejekhi zoomatshini, iijekhi zombane, iijekhi zehydraulic kunye neejekhi zomoya.Zonke ezi ntlobo zeejack ziyakwazi ukuphakamisa izinto ezinzima, kodwa iindawo zabo zokusetyenziswa, ukuphakamisa umthamo kunye noyilo luya kuhluka.

A jack hydraulicsisixhobo somatshini esisebenzisa amandla alwelo ukusebenza.Ngoncedo lweejacks ze-hydraulic, izinto ezinzima zinokuphakanyiswa ngokulula kunye nomthamo omncinci wamandla.Ngokuqhelekileyo, isixhobo sokuphakamisa sisebenzisa iisilinda ze-hydraulic ukusebenzisa amandla okuqala.Iijekhi zeHydraulic zineendlela ezininzi zezicelo kumzila kaloliwe, ukukhusela, ukwakhiwa, ukuhamba ngeenqwelomoya, izixhobo zokuphatha imithwalo, izityalo zamandla ombane wamanzi, imigodi kunye namaqonga okunyusa.Intshukumo egudileyo kunye negudileyo ye-jack yesantya eguquguqukayo phantsi kwemithwalo eyahlukeneyo okanye ephezulu yenza i-hydraulic jack ilungele zonke ezi zicelo zingentla.Ngokukwanjalo, ukusetyenziswa kweejekhi zehydraulic kunokubonelela ngokuphakamisa umthamo omkhulu kumgama omkhulu.

Xa sibheka emva kwimbali, i-patent ye-jack hydraulic jack yanikwa uRichard Dudgeon ngo-1851.

Iitanki zokugcina i-oyile okanye i-buffer tanks, iisilinda ze-hydraulic, iimpompo, ii-valve zokujonga kunye ne-valve yokukhulula ziyinxalenye ebalulekileyo yeejekhi ze-hydraulic, ezinceda ukuphakamisa izinto ezinzima.Njengazo zonke iinkqubo ze-hydraulic, itanki yokugcina i-oyile iya kugcina ioli ye-hydraulic kwaye ihambise ioli ye-hydraulic ecinezelekileyo kwi-cylinder edibeneyo ngoncedo lwepompo ye-hydraulic.Ivalve yokukhangela ephakathi kwe-cylinder kunye nempompo iya kuqondisa ukuhamba.Xa ulwelo lungena kwi-cylinder ye-hydraulic, ipiston iyanda kwaye icinezele i-cylinder yesibini ye-hydraulic.Emva kokugqiba umsebenzi, ivalve yokukhulula isetyenziselwa ukurhoxisa i-piston ye-hydraulic.Umthamo wereservoir okanye itanki yesithinteli uya kuxhomekeka kwimfuno yeoyile esebenza ngoxinzelelo loxinzelelo olukhulu ukuze isilinda sandise kwaye sirhoxe.Ulwazi oluthe vetshe malunga neejekhi zehydraulic zichazwe ngezantsi.

Isebenza njani ijekhi yehydraulic?Umgaqo osebenzayo weejacks ze-hydraulic zisekelwe kumgaqo woxinzelelo lwePascal.Oko kukuthi, uxinzelelo olusetyenzisiweyo kulwelo olugcinwe kwisitya luya kuhanjiswa ngokulinganayo kuwo onke amacala.Izinto ezibalulekileyo zejekhi ye-hydraulic yi-cylinder ye-hydraulic, inkqubo yokumpompa kunye neoli ye-hydraulic (ngokuqhelekileyo ioli).Khetha i-hydraulic jack fluids ngokuqwalasela iimpawu ezithile zolwelo (ezifana ne-viscosity, ukuzinza kwe-thermal, ukuhluzwa, ukuzinza kwe-hydrolytic, njl.).Ukuba ukhetha ioli ye-hydraulic ehambelanayo, iya kubonelela ngeyona ndlela isebenzayo, i-self-lubrication kunye nokusebenza kakuhle.Uyilo lwe-hydraulic jack luya kuba neesilinda ezimbini (enye encinci kunye nenye enkulu) eqhagamshelwe omnye komnye ngemibhobho.Zombini iisilinda zehydraulic zizaliswe ngokuyinxenye ngeoyile yehydraulic.Xa uxinzelelo oluncinci lusetyenziswe kwi-cylinder encinci, uxinzelelo luya kudluliselwa ngokulinganayo kwi-cylinder enkulu ngokusebenzisa i-incompressible fluid.Ngoku, isilinda esikhulu siya kuba nesiphumo sophindaphindo lwamandla.Amandla asetyenziswa kuwo onke amanqaku amasilinda amabini aya kufana.Nangona kunjalo, amandla enziwe yi-cylinder enkulu iya kuba phezulu kwaye ilinganisele kwindawo ephezulu.Ukongeza kwi-cylinder, ijekhi ye-hydraulic iya kubandakanya inkqubo yokumpompa ukutyhala ulwelo kwi-cylinder ngevalve yendlela enye.Le valve iya kukuthintela ukubuyiswa kwe-oyile yolwelo loxinzelelo olukhulu ukusuka kwicylinder yehydraulic.

Iibhotile zebhotilekunye neejekhi zepleyiti ziindidi ezimbini zeejekhi zehydraulic.I-bearing pad exhaswa yi-vertical shaft inoxanduva lokulinganisa ubunzima bento ephakanyisiweyo.IiJacks zisetyenziselwa ukugcinwa kweziseko zeemoto kunye nezindlu, kunye neelifti ezimfutshane ezithe nkqo.IiJacks zinokubonelela ngoluhlu olubanzi lokuphakanyiswa ngokuthe nkqo.Ngoko ke, ezi jacks zisetyenziswa ngokuqhelekileyo kwishishini lemigodi.Ngokungafaniyo nesiphakamisi sebhotile, ishafti ethe tyaba ityhala i-crank ukuba iqhagamshele kwindawo yokunyusa, ize iyiphakamise ngokuthe nkqo.

Sinokufikelela kwizigqibo emva kokuxoxa ngeendlela zokusombulula iingxaki kwiijekhi zehydraulic.Kufuneka ndenze ntoni ukuba ijekhi yehydraulic ayikwazi ukuphakamisa izinto?Inqanaba le-oyile eliphantsi linokuba ngunobangela wale mpazamo.Ngoko ke, okokuqala, kufuneka uhlolisise izinga leoli.Ukuba ufumanisa ukuba isixa seoli kwisixokelelwano asanelanga, nceda ugcwalise amafutha.Ukuvuza okanye ukungaphumeleli kwetywina kusenokuba ngomnye unobangela wale meko.Ukuba i-gasket yonakalisiwe, i-gasket kwi-cylinder yoxinzelelo kufuneka itshintshwe.
