Kusiyana kwa valve ndi solenoid valve

Mavavu ofananira amagawidwa kukhala ma valve ofananira molunjika ndi ma valve obwerera kumbuyo. Kuthamanga kwa mpweya wosinthika. Valve ya solenoid imatha kugwira ntchito ngati chosinthira. Valve ya solenoid ndi valavu yomwe imatha kuyendetsedwa ndikuzimitsa, ndipo valavu yofanana ndi valve yomwe imatha kuyendetsa digiri yoyamba. Kunena mwachidule, valavu yofananira imagwiritsidwa ntchito pokonza kupanikizika. Liwiro. Wawamba solenoid valavu reversing kanthu

Valavu yaikulu yothandizira imayikidwa pamwamba ndi m'munsi mwa valavu yaikulu yolamulira, imodzi pamwamba ndi pansi. Valavu imayika kupanikizika kwakukulu kwa hydraulic system yonse kuti igwire ntchito. Pamene kupanikizika kwa dongosolo kumadutsa kupanikizika kwa valve yaikulu yothandizira, valavu yaikulu yothandizira imatsegula kayendedwe ka mafuta a thanki yobwereranso kuti iwononge mafuta a hydraulic kubwerera ku thanki kuti ateteze dongosolo lonse la hydraulic ndikupewa kuthamanga kwa mafuta kwambiri. Valavu yayikulu yothandizira Vavu yomwe ili pagulu la valavu yogawa, udindo wake ndikuchepetsa kupanikizika kwakukulu kwa dongosolo lonse la hydraulic kuteteza dongosolo lonse kuti lisawonongeke, ngati kasupe wa valavu akusweka kapena kupanikizika kumakhala kotsika kwambiri. zidzatsogolera kupanikizika kwa dongosolo lonselo ndi lochepa kwambiri, chifukwa kupanikizika kwa valve yaikulu yothandizira kumapangitsa kuti ma hydraulic system asamakhazikitse kupanikizika kofunikira kuti zigwiritsidwe ntchito bwino. Mafuta othamanga kwambiri a pampu sangathe kulimbikitsa ntchito yachizolowezi ya actuator, padzakhala pang'onopang'ono kapena ngakhale palibe zochita za galimoto yonse, panthawiyi ziyenera kufufuzidwa kuti zisinthe kapena kusintha valve yaikulu yothandizira.
