Njengenxalenye engundoqo yothumelo lolwelo kunye neenkqubo zolawulo, amacandelo e-hydraulic abambe ukubaluleka kwesayensi engenakubuyiselwa kushishino lwangoku, i-aerospace, oomatshini bobunjineli, kunye nesayensi yokhuselo kunye netekhnoloji. Ngothumelo kunye noguqulo lwamandla oxinzelelo lolwelo, bavumela amandla aphezulu{{1},{2}}ukuchaneka okuphezulu, kunye nolawulo lwamandla oluthembeke kakhulu, babe yinkxaso yobuchwephesha ephambili ekusebenzeni kakuhle kweenkqubo zoomatshini.
Ukusuka kwimbono yesayensi, amacandelo e-hydraulic, esekelwe kumthetho wePascal, ahambisa uxinzelelo ngokusebenzisa i-fluid medium medium, ukuguqula amandla omatshini kumandla alawulwayo aphantsi komhlaba. Le ndlela yokuhambisa amandla ibonelela ngeenzuzo ezibalulekileyo ezifana nokuxinana kwamandla aphezulu, impendulo ekhawulezayo, kunye nokuhanjiswa okugudileyo, okwenza ukuba ifaneleke ngokukodwa kwizicelo ezifuna i-torque ephezulu okanye imithwalo ephezulu. Umzekelo, izixhobo ezinzima ezifana ne-hydraulic excavators kunye ne-cranes zixhomekeke kwiisilinda ze-hydraulic kunye neenjini ze-hydraulic zolawulo oluchanekileyo lwentshukumo. Ixabiso labo lezenzululwazi lisekugqibeleni nasekusetyenzisweni kobunjineli kwemigaqo yoomatshini.
Kwinqanaba lokuyila kobuchwepheshe, uphando kunye nophuhliso lwamalungu oxinzelelo lwamanzi lukhuthaze umnqamlezo -umanyano lwenzululwazi yemathiriyeli, ubuchwephesha bolwelo, kunye nethiyori yolawulo oluzenzekelayo. Iinkqubo zale mihla zehydraulic, ngokudityaniswa kwezinzwa kunye namaqela evalufa akrelekrele, ukufikelela kulawulo oluvaliweyo{2}}nolawulo oluguquguqukayo, luphucula kakhulu ukusebenza okuguquguqukayo kwenkqubo kunye nokuthembeka. Ngaphaya koko, imfuno ekhulayo yogcino lwamandla kunye nokukhuselwa kokusingqongileyo ikhuthaze abaphandi ukuba baphuhlise{4}}ukuvuza okuphantsi, okuphakamileyo{5}}ubuchule obuphezulu be-hydraulic components, ezifana ne-electro-ivalvu zehydraulic proportional kunye ne-hydraulics yedijithali, ukwandisa ngakumbi imida yenzululwazi yezahlulo ze-hydraulic.
Ukubaluleka kwezenzululwazi kwamacandelo e-hydraulic nawo kubonakaliswe kwimpembelelo yawo kwiinkalo ezininzi. Uyilo lwabo lubandakanya iinkalo ezingundoqo ezifana ne-thermodynamics, i-tribology, kunye ne-mechanical dynamics, ngelixa ukusetyenziswa kwazo kwiindawo ezingqongileyo ezigqithisileyo (ezifana nolwandle olunzulu kunye nendawo) kuqhube ukuphumelela kwimathiriyeli{1}}ephezulu kunye nokudleka{2}}. Amacandelo e-Hydraulic ayilona litye lembombo lobuchwephesha bobunjineli kuphela kodwa kunye nesithuthi esibalulekileyo senzululwazi kuphononongo loluntu lolawulo oluntsonkothileyo kunye nokusetyenziswa kwamandla ngokufanelekileyo.
