Ifanele i-bulldozer CAT 826G proportional solenoid valve Rotary solenoid valve 147-5399

I-valve ye-solenoid ye-Proportional iyi-valve ekhethekile yokulawula i-solenoid, isimiso sayo sokulawula ukulawula ukuvulwa kwe-valve ngokusebenzisa isignali yomyalo wokufakwa kwangaphandle, ukuze ukugeleza kokulawula nokucindezela kuhlale kugcina isilinganiso esifanayo nesignali yomyalo. Isebenzisa ubuchwepheshe be-"position feedback", obungakwazi ukulungisa ngokunembile indawo ye-valve ngokusho kwesignali yokulawula ukugeleza, ukuze kuzuzwe izidingo zokulawula ezinembile, ngakho-ke isetshenziswa kabanzi ekulawuleni okunembile kwesistimu ye-hydraulic.
 

Umgomo oyinhloko we-proportional solenoid valve ukuthi isignali yokulawula ukugeleza namandla okulawula asetshenziswa njengomthombo wamandla wekhoyili kagesi, ukuze i-electromagnetic ilawule ukuvulwa kwe-valve, ngakho ukuvulwa kwe-valve kucishe kulingane usayizi wesiginali yokulawula ukugeleza. Ngokuhambisana nokugeleza okuhlukile, indawo yokulawula ngayinye inenani elihlukile lokugeleza, elibuyiselwa kusilawuli sokugeleza, isilawuli sokugeleza singakwazi ukulungisa indawo ye-valve ngokusho kwesignali yokuphuma yesayizi efanayo nokugeleza lapha, ukuze ukufeza izidingo zokulawula ezinembile.

Ukusetshenziswa kwe-valve ye-excavator solenoid

I-valve ye-electromagnetic ye-excavator iyingxenye eyisisekelo ezenzakalelayo esetshenziselwa ukulawula uketshezi lwe-excavator, okungokwe-actuator, futhi ayikhawulelwe ku-hydraulic ne-pneumatic. Isetshenziswa ezinhlelweni zokulawula izimboni ukulungisa isiqondiso semidiya, ukugeleza, isivinini kanye neminye imingcele. I-2, i-valve ye-solenoid ingahlanganiswa neziyingi ezihlukene ukuze kuzuzwe ukulawula okufunayo, futhi ukunemba nokuguquguquka kokulawula kungaqinisekiswa. Kunezinhlobo eziningi zamavalvu e-solenoid, ama-valve e-solenoid ahlukene adlala indima ezindaweni ezahlukene zohlelo lokulawula, okuvame ukusetshenziswa kakhulu ama-valve okuhlola, ama-valve okuphepha, ama-valve okulawula isiqondiso, ama-valve okulawula isivinini nokunye.

I-electromagnetic voltage ye-DC imvamisa ingu-24 volts. Izinzuzo zayo ziwumsebenzi onokwethenjelwa, hhayi ngenxa yokuthi i-spore ibambekile futhi yashiswa, impilo ende, usayizi omncane, kodwa amandla okuqala mancane kune-electromagnetic ye-AC, futhi uma kungekho ukunikezwa kwamandla ka-DC, isidingo semishini yokulungisa. Ukuze kuthuthukiswe ukwethembeka nokusebenza kwe-valve ehlehlayo kagesi, eminyakeni yamuva nje, i-electromagnetic emanzi isetshenziswa kabanzi ekhaya nakwamanye amazwe, lo magnethi kanye ne-slide valve push rod akudingeki ukuthi uvalwe, uqede ukungqubuzana endaweni. Indandatho yokuvala emise okwe-O, ikhoyili yayo kagesi ngaphandle ivalwe ngokuqondile ngepulasitiki yobunjiniyela, hhayi elinye igobolondo lensimbi, eliqinisekisa ukwahlukanisa, kodwa futhi elikhuthaza ukushabalalisa ukushisa, umsebenzi othembekile, Umthelela ophansi, impilo ende.
Kuze kube manje, i-valve ye-solenoid ekhaya nakwamanye amazwe ihlukaniswe ngezigaba ezintathu ngokomthetho (okungukuthi: uhlobo oluqondile oluyibamba, uhlobo lomshayeli wesinyathelo sengane), futhi kusukela umehluko wesakhiwo se-valve disc kanye nomehluko wezinto ezibonakalayo nomgomo uhlukaniswe izigaba eziyisithupha. (isakhiwo se-diaphragm esisebenza ngokuqondile, isakhiwo sepuleti eliphindwe kabili, isakhiwo sefilimu yomshayeli, isakhiwo se-piston esisebenza ngokuqondile, isakhiwo se-piston esiyisinyathelo esiqondile, isakhiwo se-piston piston).
I-valve ye-solenoid esebenza ngokuqondile:
Isimiso: Uma unamandla, amandla kazibuthe kagesi akhiqizwa ikhoyili kagesi aphakamisa ingxenye yokuvala esihlalweni, futhi ivalvu iyavuleka; Lapho amandla ecishiwe, amandla kazibuthe kagesi ayanyamalala, intwasahlobo icindezela ingxenye yokuvala esihlalweni, futhi i-valve ivaliwe.
Izici: Ingasebenza ngokujwayelekile ngaphansi kwe-vacuum, ingcindezi engemihle kanye nengcindezi enguziro, kodwa ububanzi ngokuvamile abudluli ku-25mm.
