Izingxenye zemishini yokwakha SV98-T3003 24V ye-John Deere solenoid valve

Ukuhlaziywa nokuqedwa kwe-valve ye-pressure ye-proportional pressure

Ngenxa yokuthi i-valve ye-proportional pressure isekelwe kuphela kwi-valve yokucindezela evamile, isibambo somlawuli sithathelwa indawo yi-proportional electromagnet. Ngakho-ke, amaphutha ahlukahlukene akhiqizwa i-valve yokucindezela evamile, ezophinde ikhiqize izimbangela zephutha kanye nezindlela zokuqeda i-valve yokucindezela evamile nazo zisebenza ngokugcwele ku-valve ye-proportional pressure ehambisanayo (njenge-valve yokusiza ehambisanayo), engase kusingathwa ngereferensi. Ngaphezu kwalokho:

① Uzibuthe olinganiselayo awukho wamanje, ukuze ukwehluleka kokulawulwa kwamandla kagesi ngalesi sikhathi kungahlaziywa ngokuya ngokuqukethwe okungenhla "(1) kwephutha likazibuthe kagesi". Lapho kwenzeka ukwehluleka kokulawulwa kwamandla kagesi, ungaqale uhlole inani lamanje ngemitha kagesi ukuze unqume ukuthi kunenkinga ngomjikelezo wokulawula we-electromagnetic, noma inkinga nge-proportional electromagnet, noma inkinga ngengxenye ye-valve kungaba uphawu.

② Nakuba amandla amanje ageleza kukazibuthe olinganiselayo akaliwe, kodwa ingcindezi ayikhuphuki nhlobo, noma ingcindezi edingekayo ayitholakali, phakathi kwesilawuli se-proportional pilot pressure (valve yokukhulula) kanye ne-valve enkulu yokusiza, isilawuli semanuwali somshayeli. yevalvu yokusiza yomshayeli evamile isagciniwe, edlala indima yevalvu yokuphepha lapha. Lapho ingcindezi yokulawula i-valve iphansi kakhulu, nakuba i-electromagnetic proportional through the current ikaliwe, kodwa ingcindezi ayikhuphuki, uma i-valve set pressure iphansi kakhulu, ukugeleza komshayeli kusuka ku-valve kugeleza kubuyela ethangini, ukuze ingcindezi ayifiki. Kulokhu, ukucindezela kokumiswa kwe-valve kufanele kunyuswe cishe ngo-1MPa kunokucindezela okukhulu kokusebenza kwe-valve.

(3) Amanje ageleza kukazibuthe olinganiselayo makhulu kakhulu, kodwa umfutho awukakakhuphuki, noma ingcindezi edingekayo ayikwazi ukubhekwa ngalesi sikhathi ukumelana nekhoyili kazibuthe olinganiselayo, uma kungaphansi kakhulu kwenani elishiwo, khona-ke isifunda sangaphakathi sekhoyili ye-electromagnet siphukile; Uma ukumelana nekhoyili ye-electromagnet kujwayelekile, khona-ke ukuxhumana ne-proportional amplifier kufushane. Ngalesi sikhathi, i-proportional electromagnet kufanele ishintshwe, futhi uxhumano kufanele luxhunywe, noma i-rewound coil kufanele ifakwe.
