Izigxivizo ze-hydraulic zisetshenziswa kumasilinda ukuvala izindawo zokuvula phakathi kwezingxenye ezahlukahlukene ze-hydraulic cylinder.
Ezinye izimvu zamanzi zibunjiwe, ezinye ziyimishini, ziklanywe ngokucophelela futhi zenziwa ngokunembile.Kunezimpawu eziguquguqukayo nezimile.Ama-Hydraulic seal afaka izinhlobo ezahlukene zezimpawu, ezifana ne-piston seal, rod seal, buffer seal, wiper seal, izindandatho eziqondisayo, o izindandatho kanye ne-backup seal.
Izinhlelo zokuvala zibalulekile ngoba zigcina imidiya ewuketshezi kanye nengcindezi yokusebenza kwesistimu ngaphakathi kanye nokungcola ngaphandle kwamasilinda.
Izinto ezisetshenziswayo zidlala indima enkulu ekusebenzeni nasekuphileni kwezimvu zamanzi.Ngokuvamile, izimpawu ze-hydraulic zivalwa ezimweni ezihlukahlukene zokusebenzisa kanye nezimo zokusebenza, njengebanga lokushisa elibanzi, ukuthintana noketshezi oluhlukahlukene lwe-hydraulic kanye nemvelo yangaphandle kanye nezingcindezi eziphezulu namandla okuxhumana.Izinto zokufaka uphawu ezifanele kufanele zikhethwe ukuze kuzuzwe impilo yesevisi enengqondo nezikhawu zesevisi.
Ama-piston seal agcina ukuxhumana okuvalekayo phakathi kwe-piston ne-cylinder bore.I-piston rod enyakazayo ikhiqiza ingcindezi ephezulu kuphawu lwe-piston okwandisa amandla okuxhumana phakathi kwe-seal nendawo yesilinda.Ngakho izakhiwo ezingaphezulu zezindawo zokuvala zibalulekile ekusebenzeni kahle kophawu.Ama-piston seal angahlukaniswa abe yi-single-acting(ingcindezi esebenza ohlangothini olulodwa kuphela) kanye ne-double acting (ingcindezi esebenza nhlangothi zombili) izimpawu.
I-Rod ne-buffer seals zigcina ukuthintana okuvalekayo ekuhambeni kokuslayida phakathi kwekhanda le-cylinder ne-piston rod.Ngokuya ngohlelo olusetshenziswayo, isistimu yokuvala izinduku ingaba ne-rod seal kanye ne-buffer seal noma i-rod seal kuphela.
Ama-wiper seal noma ama-dust seal afakwa ohlangothini lwangaphandle lwekhanda le-cylinder ukuvimbela ukungcola ekungeneni komhlangano we-cylinder kanye nesistimu ye-hydraulic.Ngoba amasilinda asebenza ngezindlela ezihlukahlukene zokusetshenziswa kanye nezimo zemvelo, kuhlanganise nokuchayeka othulini.Ngaphandle kwe-wiper seal, i-piston rod ehlehlisayo ingathutha ukungcola kuyifake kusilinda.
Imihlahlandlela evame ukusetshenziswa kumasilinda asebenza ngogesi izindandatho eziqondisayo (indandatho yokugqoka) kanye nemicu yomhlahlandlela.Imihlahlandlela yenziwe ngezinto ze-polymer futhi ivimbela ukuthintana kwensimbi kuya kwensimbi phakathi kwezingxenye ezihambayo kusilinda esisebenza nge-hydraulic.
Amasongo e-O asetshenziswa ezinhlelweni eziningi, iyisixazululo esivamile sokuvala, sigcina amandla okuxhumana okuvalwa ngokushintsha kwe-radial noma kwe-axial ocingweni phakathi kwezingxenye ezimbili.
