Kwa John Deere 310J 843K 310K hydraulic solenoid valve KV25678 SV98-T39S 12V

Mfundo yogwirira ntchito ya proportional electromagnetic control valve imayambitsidwa

Zimatengera mfundo ya solenoid on-off valve: mphamvu ikatha, kasupe amakankhira pachimake pampando, kuchititsa kuti valavu itseke. Koyiloyo ikapatsidwa mphamvu, mphamvu yamagetsi yopangidwa ndi electromagnetic imapambana mphamvu yamasika ndikukweza pachimake, motero kutsegulira valavu. Valavu yofananira ya solenoid imapanga zosintha zina pamapangidwe a valavu ya solenoid: imapanga malire pakati pa mphamvu yamasika ndi mphamvu yamagetsi yamagetsi pansi pa koyilo iliyonse. Kukula kwa koyilo yapano kapena kukula kwa mphamvu yamagetsi kumakhudza kugunda kwa plunger ndi kutseguka kwa ma valve, ndipo kutsegula kwa valve (kuyenda) ndi koyilo (chizindikiro chowongolera) ndiubwenzi wabwino kwambiri. Direct acting proportional solenoid valve imayenda pansi pa mpando. Sing'anga imayenda kuchokera pansi pa mpando, ndipo mayendedwe a mphamvu ndi ofanana ndi mphamvu yamagetsi, ndipo mosiyana ndi mphamvu ya masika. Choncho, m'pofunika kukhazikitsa ziwerengero zazikulu ndi zazing'ono zomwe zimagwirizana ndi zomwe zimagwira ntchito (coil current) pakugwira ntchito. Valavu yofananira ya solenoid ya Drey fluid imatsekedwa (NC, yomwe nthawi zambiri imatsekedwa) mphamvu ikazimitsidwa.

   Solenoid valve fault alarm njira yothetsera mavuto

Pamene chofukula cha Kobelco chikuwonekera D prefix ndi E prefix alarm code, monga D012, E013, ndi vuto la valve solenoid; Pamene code ya alamu ikuyamba ndi chilembo cha D ikukumana, ndilo vuto la valve solenoid, ndipo pambuyo pake abwenzi akhoza kufunsa za vutolo, malingana ndi malo enieni a malangizo otsatirawa kuti apeze zigawo zoyenera ndikuthetsa vutolo panthawi. (Tengani zitsanzo za mndandanda wa Kobelco SK-8 monga chitsanzo) Pezani malo a valve solenoid ndikusintha ndi valavu yosinthika ya solenoid pafupi nayo. Ngati alamu ikutha ndipo ma alarm ena apangidwa, ayenera kukhala chifukwa cha valve solenoid.

Kuwonjezera pa vuto la valve solenoid palokha, pakhoza kukhala vuto la mzere, ndipo pali adaputala pakati pa mzere ndi bolodi la makompyuta, zomwe zimafuna ogwira ntchito kuti ayang'ane chingwe chowongolera.

Excavator proportional solenoid valve momwe mungadziwire zabwino kapena zoyipa

1, kudziwa ngati valavu solenoid y2 kutseka mosamalitsa kuchotsa galimoto kwa solenoid valavu y2 mipope mafuta awiri, ndi ntchito mapulagi awiri kutsekereza injini mapeto a madoko awiri mafuta, ndiyeno ntchito chokweza chachikulu, ngati ntchito bwinobwino, kusonyeza. kuti cholakwika chochokera ku solenoid valve y2 chatsekedwa momasuka; Ngati akadali achilendo, m'pofunika kufufuza mbali zake.

2, dziwani ngati pali vuto ndi loko ya hydraulic, choyamba sinthani zokhoma zake ziwiri, ngati sizikugwira ntchito, kenako chotsani loko kuti muyang'ane mosamala, ngati simungathe kupeza chifukwa, mutha kugwiritsa ntchito loko kuchita mayeso oyika kuti mudziwe chomwe chalephereka. Chifukwa loko ya hydraulic ya winch yachiwiri ndi yofanana ndi ya winchi yayikulu, loko ya winchi yachiwiri imathanso kubwerekedwa kuti muzindikire mtundu wa loko ya winchi yayikulu poisintha imodzi ndi imodzi. Ngati maloko onse awiri ali bwino, pitani ku sitepe yotsatira.
