Izinga lokushisa lephampu yekheshi likhuphuka kakhulu ngenxa yezizathu ezine ezilandelayo:
Igebe elihambisanayo phakathi kwezingxenye ezihambayo empompini lincane kakhulu, ukuze izingxenye ezihambayo zibe sesimweni sokungqubuzana okomile kanye ne-semi-dry friction, futhi ukushisa okuningi kukhiqizwa;ukuthwala kushile;ipuleti lokusabalalisa uwoyela noma i-rotor ivaliwe;phakathi kwe-rotor nepuleti lokusabalalisa uwoyela I-axial clearance inkulu kakhulu, ukuvuza kubi kakhulu futhi ukushisa kukhiqizwa.
Iphampu ye-hydraulic ingenye yezingxenye ezibaluleke kakhulu zesistimu ye-hydraulic yokuphakama okumile, enikeza amandla anamandla.Njengengxenye ebalulekile ye-elevator, ipompo ye-hydraulic ibaluleke kakhulu ekusebenzeni kwayo okuvamile.Uma nje iphampu ye-hydraulic ihluleka, izoba nomthelela ekusetshenzisweni okujwayelekile kwe-lift.
Ezinkingeni ezivamile, kuzoba nokugeleza kokuphumayo okunganele noma akukho okuphumayo kokugeleza kwepompo ye-hydraulic.Ziningi izizathu zokungaphumeleli kokuphuma kwephampu ye-hydraulic, kodwa lokhu kudinga ukulungiswa into ngayinye.Isizathu sokushisisa ngokweqile kwepompo ye-hydraulic ye-lift engaguquki ukuthi ukusebenza kahle kwemishini kuphansi noma ukusebenza kahle kwe-volumetric kuphansi.Ngenxa yokungasebenzi kahle kwemishini kanye nokungqubuzana okukhulu kwemishini, ukulahleka kwamandla emishini kubangelwa.Ngenxa yokusebenza kahle kwevolumu ephansi, inani elikhulu lamandla asebenza ngaphansi kwamanzi liyalahleka, futhi amandla emishini alahlekile namandla adonswa amanzi abe amandla okushisa.
