Cholinga chachikulu cha ma hydraulic connectors ndikuwonetsetsa kuti ziro-zimatulutsa madzi otayikira (nthawi zambiri mafuta a hydraulic). Pansi pazovuta kwambiri-zonse (ma hydraulic system amakono amatha kugwira ntchito mopanikizika ndi 35 MPa kapena kupitilira apo), ngakhale kutayikira pang'ono kungayambitse kutayika kwa mphamvu, kuwononga chilengedwe, komanso zochitika zachitetezo. Chifukwa chake, mapangidwe osindikizira a cholumikizira ndikofunikira. "Metal-chisindikizo" nthawi zambiri amagwiritsidwa ntchito, pomwe ulusi wodzaza ulusi umakanikiza mphete yosindikizira kwinaku akuthandizira kulimba kwa nyumba yachitsulo kuti ikanize kupunduka pansi pa kupsyinjika kwakukulu.
Kukana kukakamiza ndi chizindikiro chachikulu cha khalidwe la cholumikizira. -zolumikizira zama hydraulic zamtundu wapamwamba zimayenera kuyesedwa mwamphamvu, kuphatikizira kuyezetsa static pressure hold (kuti atsimikizire kuti ali ndi chisindikizo nthawi yayitali-kuthamanga kwambiri) komanso kuyezetsa kugunda kwa mtima (kuti ayese kusinthasintha kwa kuthamanga kwa makina poyambitsa ndi kutseka). Kukana kutopa ndikofunikira: kusinthasintha pafupipafupi kungayambitse ma microcracks m'nyumba zachitsulo. -Njira zopangira zolondola kwambiri (monga kutembenuza CNC ndi kufota mwatsatanetsatane) ndi njira zochizira kutentha (monga kuzimitsa ndi kutenthetsa kuti zikhale zolimba) zitha kukulitsa moyo wantchito ya cholumikizira.
Kuphatikiza pa kusindikiza komanso kukana kukanikiza, zolumikizira ma hydraulic ziyeneranso kusinthira kumayendedwe osiyanasiyana. Mwachitsanzo, m'malo otentha kwambiri-monga makampani opanga zitsulo), zotsekera zimayenera kukhala zapamwamba-zosagwira kutentha kwa fulororuba; mu zipangizo zowononga (monga ma marine hydraulic systems), chipolopolocho chiyenera kupangidwa ndi chitsulo chosapanga dzimbiri kapena pamwamba-chokuta; m'mafakitale apadera monga chakudya ndi mankhwala, zinthu zophatikizana zimafunikira kuti zikwaniritse miyezo yaukhondo (monga 316L chitsulo chosapanga dzimbiri).
