Excavator hydraulic pump proportional solenoid valve 200-6210

Spool ya proportional solenoid valve imayang'aniridwa ndi ma electromagnets ofananira, kotero kuti kuthamanga kapena kutuluka kwake kukhale kolingana ndi zomwe zikulowetsa pano. Chifukwa chake, kukakamiza kotulutsa kapena kutuluka kumatha kuyendetsedwa mosalekeza mwa kusintha chizindikiro cholowera. Ma valve ena amakhalanso ndi ntchito yoyang'anira kukula kwa kayendedwe kake ndi njira. Malinga ndi valavu yofananira imathanso kugawidwa kukhala: valavu yofananira, valavu yoyenda molingana, valavu yobwerera m'magulu atatu.
Valavu yofananira imagwiritsidwa ntchito m'malo mwa gawo loyang'anira loyambirira ndi ma electromagnet yofananira pa valavu yamagetsi wamba, valavu yothamanga ndi valavu yowongolera, ndikuwongolera patali kupanikizika, kuyenda kapena mayendedwe akuyenda kwamafuta molingana ndi mawonekedwe amagetsi olowera mosalekeza komanso molingana. . Ma valve ofananira nthawi zambiri amakhala ndi chiwongola dzanja, ndipo kuthamanga kwa zotulutsa ndi kuthamanga kwake sikungakhudzidwe ndi kusintha kwa katundu.
Valavu yofananira imatha kuwongolera kukula kwake ndi mafunde a PWM, ndipo zotulukapo zimapitilira.
Chizindikiro cha lamulo chimakulitsidwa ndi amplifier yofananira, ndi mphamvu yofananira ndi yofanana ndi solenoid ya proportional valavu, mphamvu yofananira ya solenoid ndi kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake. kusintha njira ya madzi otaya, kuti akwaniritse udindo kapena liwiro kulamulira actuator. M'mapulogalamu ena omwe amafunikira malo apamwamba kapena kulondola mwachangu, makina owongolera otsekeka amathanso kupangidwa pozindikira kusuntha kapena kuthamanga kwa chowongolera.
