TM70301 proportional solenoid valve hydraulic futha excavator izesekeli

I-screw cartridge proportional valve iyingxenye ye-electromagnetic proportional cartridge ehlanganiswe kubhulokhi yokuhlanganisa yesekethe kawoyela. I-valve ye-screw cartridge valve inezici zohlelo lokusebenza oluguquguqukayo, ukonga amapayipi kanye nokwakheka kwezinkuni eziphansi, njll. Isetshenziswe kakhulu futhi kabanzi emishini yokwakha eminyakeni yamuva. Okuvame ukusetshenziswa Kuvunguza cartridge uhlobo valve proportional has ezimbili, ezintathu, ezine kanye multi-pass amafomu, ezimbili-indlela proportional valve main proportional throttle valve, ngokuvamile izingxenye zayo ndawonye ukwakha valve esiyinhlanganisela, ukugeleza, control ingcindezi; Izixhumanisi ezintathu
I-valve ye-proportional iyi-valve eyinhloko yokunciphisa i-proportional pressure, ephinde ibe yi-valve yokulinganisa esetshenziswa kakhulu ohlelweni lwe-hydraulic mechanical hydraulic, olusebenzisa ikakhulukazi i-hydraulic multiway valve pilot oil circuit. I-valve yokunciphisa ukucindezela okulinganayo yezindlela ezintathu ingangena esikhundleni se-valve yokushayela yesandla yendabuko yokunciphisa ukucindezela, enokuguquguquka okwengeziwe kanye nokunemba okuphezulu kokulawula kune-valve yomshayeli wezandla. Ingenziwa i-proportional servo manual manual multi-way valve njengoba kukhonjisiwe kuMfanekiso 1. Ngezimpawu zokufaka ezihlukene, i-valve yokunciphisa ingcindezi yenza i-piston ephumayo ibe nokucindezela okuhlukile noma izinga lokugeleza ukuze kuzuzwe ukulawula okulingana kokugudluka kwe-multi- indlela valve spool. Amavalvu alinganayo ekhatriji yendlela emine noma yezindlela eziningi angalawulwa ngawodwa ocingweni olusebenzayo.
I-valve yohlobo lwe-slide valve proportional, eyaziwa nangokuthi i-valve yokusabalalisa, ingenye yezingxenye eziyisisekelo zesistimu ye-hydraulic mechanical hydraulic, ekwazi ukubona isiqondiso kanye nokulawulwa kokugeleza kwe-valve eyinhlanganisela.
I-valve ye-electro-hydraulic slide valve proportional multiway valve iyisici sokulawula ukuguqulwa kwe-electro-hydraulic efanelekile, igcina umsebenzi oyisisekelo we-valve ye-multiway valve, kodwa futhi yandisa isikhundla sokusebenza kwe-servo kagesi ngokulinganayo kanye nokuzwa komthwalo nezinye izindlela zokulawula ezithuthukisiwe, yimikhiqizo eshintshwayo yemishini yokwakha.
Ngenxa yokucatshangelwa kwezindleko zokukhiqiza kanye nezidingo zokulawula ukunemba kwemishini yokwakha akuzona izici eziphakeme, i-valve ye-proportional ye-multi-way valve ayinayo inzwa yokufuduka, nokutholwa kwe-elekthronikhi nemisebenzi yokulungisa amaphutha. Ukususwa kwe-spool kuthinteka kalula ngokushintshashintsha kwengcindezi okubangelwa izinguquko zomthwalo, futhi ukubhekwa okubukwayo kuyadingeka ukuze kuqinisekiswe ukuqedwa komsebenzi ngesikhathi sokusebenza. Ukulawulwa kwe-elekthronikhi, ukusebenza kokulawula kude kufanele kunake kakhulu ithonya lokuphazamiseka kwangaphandle. Muva nje, ngokuthuthukiswa kobuchwepheshe be-elekthronikhi, abantu basebenzisa kakhulu ukupakisha kwangaphakathi
Izinzwa zokuthutha ezifana ne-dynamic transformer (LDVT) zisetshenziselwa ukuthola umnyakazo wendawo ye-spool futhi ibone ukulawulwa kwe-loop evaliwe yokufuduka kwe-spool. Le valve edidiyelwe kakhulu iqukethe i-solenoid proportional valve, inzwa yokuphendula indawo, i-amplifier yokushayela kanye namanye amasekhethi kagesi.
