Monga chimodzi mwa zinthu zomwe zimagwiritsidwa ntchito popanga zida zopulumutsira madzi, chitoliro cha mafuta a hydraulic ndi chipangizo chomwe chimagwiritsidwa ntchito potumiza mafuta a hydraulic pakati pa chida chopulumutsira madzi ndi gwero lamagetsi la hydraulic.
Chifukwa chake,mapaipi amafuta a hydraulicZipangizo zopulumutsira za hydraulic zili ndi njira ziwiri zolowera mafuta ndi njira zobwezeretsera mafuta, zomwe zimatha kugwira ntchito kawiri pa silinda ya hydraulic podutsa mafuta mbali zosiyanasiyana kuti apeze njira zosiyanasiyana zoyendera.

Chikumbutso chapadera: Chifukwa cha kusiyana kwa kuthamanga kwa ntchito, chitetezo, ndi zina zotero, machubu a hydraulic ochokera kwa opanga osiyanasiyana sangalumikizidwe ndi zida za hydraulic.
Mitundu ya ma hydraulic oil payipi olumikizirana imatha kugawidwa m'ma single interface ndi dual interface.

Kusiyana kwakukulu ndi: mawonekedwe amodzi amatha kulumikizidwa ndi kuchotsedwa pamene chida chophwanya ma hydraulic chili pansi pa kupanikizika (pano chikutchedwa pressure plugging and unplugging), zomwe zimapangitsa kuti ntchito igwire bwino ntchito; Pankhani ya mawonekedwe amodzi, chida chosinthira chimangofunika kulumikizidwa ndi kuchotsedwa kamodzi kokha, ndipo liwiro losintha la chidacho limathamanga; magwiridwe antchito otseka mawonekedwe amodzi ndi abwinoko.
