Vavu yopumulira ya hydraulic screw cartridge ku Italy RVC0.S10

Valavu yothandizira ndi hydraulic pressure control valve, yomwe makamaka imagwira ntchito yochepetsera kupanikizika kosalekeza, kuwongolera kupanikizika, kutsitsa dongosolo ndi chitetezo chachitetezo pazida zama hydraulic. Mu kachulukidwe pampu throttling regulation dongosolo, kachulukidwe mpope amapereka otaya nthawi zonse, pamene kuthamanga kwa dongosolo kumawonjezeka, kufunikira kwa kutuluka kudzachepetsedwa, panthawiyi valve yothandizira imatsegulidwa, kotero kuti kuthamanga kwambiri kubwerera ku thanki, kuonetsetsa kuti kuthamanga kwa valve yolowera, ndiko kuti, kuthamanga kwa potulutsira pampu kumakhala kosasintha. Valve yothandizira imalumikizidwa motsatizana pamayendedwe obwerera mafuta, ndipo kukhazikika kwa magawo osunthira kumbuyo kwa valavu yothandizira kumawonjezeka. Ntchito yotsitsa ya dongosololi ndikulumikiza valavu ya solenoid ndi kayendedwe kakang'ono kamene kakusefukira pamndandanda pa doko lakutali la valve yothandizira. Pamene electromagnet yapatsidwa mphamvu, doko loyang'anira kutali la valve yothandizira limadutsa mu thanki yamafuta. Panthawiyi, pampu ya hydraulic imatsitsidwa ndipo valve yothandizira imagwiritsidwa ntchito ngati valavu yotsitsa. Chitetezo cha chitetezo ntchito, pamene dongosolo likugwira ntchito bwino, valavu imatsekedwa, pokhapokha ngati katunduyo akupitirira malire omwe atchulidwa, kusefukira kumatsegulidwa, ndipo chitetezo chochuluka chimachitidwa, kotero kuti kupanikizika kwa dongosolo sikuwonjezeka.

Proportional valve ndi mtundu watsopano wa chipangizo chowongolera ma hydraulic.

Mu valavu yamagetsi wamba, valavu yothamanga ndi valavu yolowera, ma electromagnet wofananira amagwiritsidwa ntchito m'malo mwa gawo loyang'anira, ndipo kukakamiza, kuyenda kapena mayendedwe akuyenda kwamafuta kumayendetsedwa patali molingana ndi chizindikiro chamagetsi cholowera mosalekeza komanso molingana. Ma valve ofananira nthawi zambiri amakhala ndi chiwongola dzanja, ndipo kuthamanga kwake komanso kuthamanga kwake sikungakhudzidwe ndi kusintha kwa katundu.
