Ifanele i-E320 330 336GC i-proportional solenoid valve 585-9231 izesekeli ze-excavator

Isebenza kanjani i-valve ye-proportional

Ukulawula okuzenzakalelayo kungahlukaniswa ngokulawulwa kwezikhawu kanye nokulawula okuqhubekayo. Isilawuli sesikhashana siwukulawula ukushintsha. Kusistimu yokulawula umoya, i-valve yokuhlehlisa i-ON-OFF ene-frequency yokusebenza ephansi isetshenziselwa ukulawula ukuphuma komzila wegesi. Thembela ku-valve yokunciphisa ingcindezi ukuze ulungise ingcindezi edingekayo, uthembele ku-valve ye-throttle ukuze ulungise ukugeleza okudingekayo. Lolu hlelo lwendabuko lokulawula umoya womoya lufuna ukuba namandla amaningi okukhipha kanye nesivinini sokunyakaza okuningi, ludinga ama-valve okunciphisa ukucindezela okuningi, ama-throttle valve nama-valve ahlehlayo. Ngale ndlela, akuzona kuphela izingxenye ezidinga okwengeziwe, izindleko ziphezulu, ukwakheka kwesistimu kuyinkimbinkimbi, futhi izingxenye eziningi zidinga ukulungiswa ngesandla kusengaphambili. Isilawuli se-valve ye-proportional valve singesokulawula okuqhubekayo, okubonakala ngokushintsha kwenani lokuphumayo ngenani lokufakwayo (inani lamanje noma inani le-voltage), futhi kukhona ubudlelwano obuthile bokulinganisa phakathi kokukhiphayo nenani lokokufaka. Ukulawulwa kwe-proportional kungahlukaniswa kube isilawuli seluphu evulekile kanye nesilawuli seluphu evaliwe. Ukulawulwa kweluphu evaliwe yesistimu yempendulo yesignali. I-electro-hydraulic proportional valve iyisiginali ye-electromagnetic input voltage input in the valve ukuze ikhiqize isenzo esihambisanayo, ukuze i-valve esebenzayo igudluke, usayizi wembobo yevalvu ishintshe futhi iqedele ukucindezela nokugeleza kwezingxenye zokuphuma ngokulingana ne-voltage yokufaka. Ukususwa kwe-spool nakho kungabuyiselwa ngomshini, ngogesi noma ngogesi. I-valve ye-electro-hydraulic proportional valve inezinhlobo ezihlukahlukene, kulula ukuyisebenzisa ukulawula kagesi kanye nekhompyutha yezinhlelo ezihlukahlukene ze-electro-hydraulic, ukunemba kokulawula okuphezulu, ukufakwa nokusetshenziswa okuguquguqukayo, kanye nekhono eliqinile lokulwa nokungcola, kanye nezinye izinzuzo, insimu yesicelo iyakhula. . Ukukhethwa nokuqoqwa kwe-valve ye-proportional valve, i-R & D kanye nokukhiqizwa kwe-cartridge valve proportional kanye ne-proportional multiway valve kucabangela ngokugcwele izici zokusetshenziswa kwemishini yokwakha, ngokulawula umshayeli, ukuzwa komthwalo kanye nemisebenzi yesinxephezelo sokucindezela. Kubaluleke kakhulu ukwenza ngcono izinga lobuchwepheshe bemishini esebenza ngogesi ephathwayo. Ikakhulukazi, ukusebenza komshayeli wokulawula i-elekthronikhi, isilawuli kude esingenantambo kanye nokusebenza kwesilawulikude esinezintambo kubonise amathemba amahle ohlelo lokusebenza. Isimiso: Isignali yokufaka iyanda, i-valve yomshayeli we-solenoid yokushayela i-valve 1 ihlehla, futhi i-valve yomshayeli we-solenoid ephumayo engu-7 isesimweni sokusetha kabusha, khona-ke umfutho wokunikezwa komoya ungena egumbini lomshayeli 5 usuka echwebeni le-SUP nge-valve 1, ingcindezi kwekamelo lomshayeli liyakhuphuka, ukucindezela kwegesi kusebenza engxenyeni engenhla ye-diaphragm 2, khona-ke i-valve yokuhambisa umoya 4 exhunywe ne-diaphragm 2 iyavulwa, i-valve yokukhipha 3 ivaliwe, futhi ingcindezi yokuphuma iyakhiqizwa. Lokhu kucindezela okukhiphayo kubuyiselwa emuva ukuze kulawule i-loop 8 ngokusebenzisa inzwa yokucindezela 6. Lapha, ukuqhathanisa okusheshayo kwenziwa nenani eliqondiwe kuze kube yilapho ingcindezi yokuphumayo ilingana nesiginali yokufaka, okuholela ekushintsheni kokucindezela okukhiphayo ngokulingana noshintsho ku isignali yokufaka. Ngenxa yokuthi ayikho indlela yokuvala umlomo we-nozzle, i-valve ayizwelani nokungcola futhi inokwethenjelwa okuphezulu.
