I-XKAL00050 Excavator R160W9A R170W7 Ikhoyili yeValve ye-Solenoid

I-valve ye-solenoid inezingxenye ezimbili: ikhoyili kagesi kanye nengqikithi kazibuthe, nomzimba we-valve onembobo eyodwa noma ngaphezulu. Uma ikhoyili kuvalvu ye-solenoid inikwa amandla noma iphelelwa amandla, ukusebenza kwengqikithi kazibuthe kuzokwenza uketshezi ludlule emzimbeni wevalvu noma lunqamule, kushintshe indlela oketshezi oluya ngayo. Njengoba i-current idlula kukhoyili, ikhoyili ye-solenoid valve ingase ishe. Yiqiniso, imbangela yokushiswa ingase ihluke. Ake sibheke isizathu esenza ikhoyili ye-solenoid valve ishiswe.

Izizathu zangaphandle:

Ukusebenza kahle kwe-valve ye-solenoid kuhlobene eduze nokuhlanzeka kwe-fluid medium. Imidiya eminingi izoba nezinhlayiya ezincane noma ukubalwa kwemidiya. Lezi zinto ezincane zizonamathela kancane kancane enhliziyweni ye-valve futhi kancane kancane ziqine. Abantu abaningi bathole ukuthi ibisasebenza ngokujwayelekile ngayizolo, futhi ivalve yesolenoid ayikwazanga ukuvulwa ngakusasa ekuseni. Lapho ikhishwa, kwakunongqimba oluwugqinsi lwamadiphozithi ebaliwe kuvalvu. Lolu hlobo lwesimo luvamile, futhi luphinde lube yisici esiyinhloko esiholela ekushisweni kwe-valve ye-solenoid, ngoba lapho inhliziyo ye-valve inamathele, FS = 0, bese kuthi I = 6i, yamanje izokhula ngokuphindwe kasithupha, futhi ikhoyili evamile izoshiswa kalula.

Izizathu zangaphakathi:

Ukuvunyelwa okufanelekile phakathi komkhono we-spool we-valve ye-solenoid kanye ne-valve kuncane kakhulu (ngaphansi kuka-0).008mm), okuvamise ukufakwa esiqeshini esisodwa. Lapho ukungcola kwemishini kungena noma uwoyela wokugcoba umncane kakhulu, kulula ukubhajwa. Indlela yokwelapha kungaba ukubhoboza intambo yensimbi embotsheni encane esekhanda ukuze ibuyele emuva. Isixazululo esibalulekile ukukhipha i-solenoid valve, ukukhipha umgogodla we-valve nomkhono we-valve, bese usebenzisa i-CCI4. Ukuhlanza ukukhuthaza ukuguquguquka kwe-valve core kumkhono we-valve. Lapho uqaqa, naka ukulandelana kokufakwa kanye nendawo yezintambo zangaphandle zengxenye ngayinye, hlanganisa futhi futhi ucingo ngendlela efanele, futhi uhlole ukuthi imbobo yomjovo kawoyela ivinjiwe yini nokuthi amafutha okugcoba anele yini. Uma ikhoyili ye-valve ye-solenoid ishisiwe, izintambo ze-valve ye-solenoid zingasuswa futhi zikalwe nge-multimeter. Uma ivuliwe, ikhoyili ye-solenoid valve iyashiswa. Isizathu siwukuthi ikhoyili imanzi, okuholela ekwakhiweni okungalungile kanye nokuvuza kwamagnetic, okuholela ekushiseni ngokweqile kwamanje kanye nokushiswa kwekhoyili, ngakho imvula ivinjelwa ukungena ku-valve ye-solenoid. Ngaphezu kwalokho, intwasahlobo iqinile, amandla okubuyisela emuva makhulu kakhulu, inani lokuphenduka kwekhoyili lincane kakhulu, futhi amandla okumunca awanele, okungase futhi kukhuthaze ukushiswa kwekhoyili. Esimeni esiphuthumayo, inkinobho yesandla kukhoyili ingasebenza ngokujwayelekile ukuze iqedele indawo ka-"0" bese ishaya indawo ethi "1", ngaleyo ndlela ibangele ukuthi ivalvu ivuleke.
