Umgomo oyinhloko wezixhumi ze-hydraulic ukuqinisekisa ukuthi -ukuvuza kokudluliswa koketshezi (imvamisa uwoyela we-hydraulic) uziro. Ngaphansi kwezimo zokucindezela okuphezulu-(amasistimu esimanjemanje asebenza ngamanzi angasebenza ngaphansi kwengcindezi engu-35 MPa noma ngaphezulu), ngisho nokuvuza okuncane kungaholela ekulahlekeni kwamandla, ukungcoliswa kwemvelo, ngisho nezigameko zokuphepha. Ngakho-ke, ukwakheka kokubeka uphawu kwesixhumi kubalulekile. Isakhiwo esiyinhlanganisela "yensimbi-se-seal" ngokuvamile sisetshenziswa, lapho ukulayishwa kuqala kochungechunge kucindezela indandatho yokuvala kuyilapho kusebenzisa ukuqina kwendlu yensimbi ukumelana nokuguqulwa ngaphansi kwengcindezi ephezulu.
Ukumelana nokucindezela kuyinkomba eyinhloko yekhwalithi yesixhumi. -Izixhumi ze-hydraulic zekhwalithi ephezulu kufanele zihlole ingcindezi eqinile, okuhlanganisa nokuhlolwa kokubanjwa kwengcindezi emile (ukuqinisekisa ukuvaleka ngaphansi-kwesikhathi eside sokucindezela okuphezulu) nokuhlolwa kokushaya kwenhliziyo (ukuze balingise ukushintshashintsha kwengcindezi phakathi nokuqaliswa kwesistimu nokuvala shaqa). Ukumelana nokukhathala nakho kubalulekile: ukushintshashintsha njalo kwengcindezi kungabangela ama-microcracks endlini yensimbi. Izinqubo-zokukhiqiza ezinembayo eziphezulu (ezifana nokujika kwe-CNC nokufoja ngokunemba) nezindlela zokwelapha ukushisa (ezifana nokucisha nokushisa ukuze kuthuthukiswe ukuqina) zinganweba ngempumelelo impilo yesevisi yesixhumi.
Ngokungeziwe ekubekeni uphawu nokumelana nokucindezela, izixhumi ze-hydraulic kumele futhi zivumelane nezimo ezihlukahlukene zokusebenza. Isibonelo, ezimeni-zezinga lokushisa eliphezulu (njengemboni yensimbi), into yokuvala idinga ukuba{2}}i-fluororubber ekwazi ukumelana nokushisa okuphezulu; kumithombo yezindaba ebolayo (njengamasistimu e-hydraulic yasolwandle), igobolondo lidinga ukwenziwa ngensimbi engagqwali noma{3}}elinamekwe; ezimbonini ezikhethekile ezifana nokudla nemithi, izinto ezihlangene ziyadingeka ukuze kuhlangatshezwane nezindinganiso zokuhlanzeka (ezifana ne-316L yensimbi engagqwali).
