I-SV90-G40R i-valve ye-solenoid ye-Excavator yokulayishwa kwe-proportional valve

Ukulawulwa komshayeli nokulawula okukude kwe-electro-hydraulic proportional valve yemishini yokwakha
Ukuthuthuka kwamavalvu alinganayo kagesi kanye nezinye izinto ezikhethekile kwenze ukulawula kukagesi kwezinhlelo ezihlukahlukene njengegiya, isiteringi, ukubhuleka kanye nemishini yokusebenza yezimoto zobunjiniyela kwaba ngokoqobo. Isidingo esijwayelekile
Ukususwa kwendlela yokuphumayo kungenziwa kusetshenziswa umshayeli we-valve we-multiway osebenzisa i-proportional servo control efana ne-Figure 1. Ukusebenza kukagesi kunezinzuzo zokuphendula okusheshayo, i-wiring eguquguqukayo, ingakwazi ukufeza ukulawula okudidiyelwe kanye nokuxhumana okulula nekhompyutha, njll. umshini wokwakha i-valve engu-hydraulic isiwukulawula ngokwengeziwe umshayeli we-electro-hydraulic proportional valve (noma i-electro-hydraulic switch valve) esikhundleni sokusebenza okuqondile okwenziwa ngesandla noma ukulawulwa komshayeli we-hydraulic osebenzisa izindlela eziningi. Enye inzuzo ebalulekile yokusebenzisa ama-electro-hydraulic proportional valves (noma ama-electro-hydraulic on-off valves) ukuthi inani lezibambo zokusebenza lingancishiswa kakhulu ezimotweni zobunjiniyela, okwenza ukwakheka kwe-cab kube lula, kunganciphisa ngempumelelo inkimbinkimbi yokusebenza, futhi inokubaluleka okusebenzayo okubalulekile ekwenzeni ngcono izinga nokusebenza kahle komsebenzi. I-multi-disc electro-hydraulic proportional valve kanye ne-on-off valve ingalawulwa ngempumelelo ngokusebenzisa i-rocker eyodwa. I-rocker ingakwazi ukubona ukulawula okulinganayo noma isilawuli sokushintsha kukho kokubili i-X axis kanye ne-Y axis direction, futhi uhlelo lokusebenza lulula kakhulu.
Ngokuthuthuka okusheshayo kobuchwepheshe bokuxhumana obungenawaya bedijithali, kube nokusebenza okuzinzile, umsebenzi onokwethenjelwa, ofanele uhlelo lokulawula okukude okungenantambo lwemishini yokwakha, ukuxhumana kwesilawuli kude emishinini ephathwayo.
Idivayisi eyamukelayo ingaguqula isignali yomsakazo eyamukelwe ibe isignali elinganayo yokulawula i-electro-hydraulic proportional valve kanye nesignali yokushintsha yokulawula i-electro-hydraulic switching valve, kanye nesignali ehambisanayo yokulawula kwamanye amadivaysi, ukuze ukusebenza ngesandla kwasekuqaleni kwengxenye ngayinye kungamukela isilawuli kude somyalelo wesiginali kagesi futhi kwenze isenzo esihambisanayo
Imishini yokwakha isiphenduke imishini yokwakha elawulwa kude.
