Excavator hydraulic pump solenoid valve R901155051

Iivalvu ze-Solenoid yinto eqhelekileyo yokulawula esetyenziselwa ukulawula ukuhamba kweegesi okanye ulwelo. Iqulethwe ngumbane we-electromagnetic kunye nevalve, kwaye ukutshintshwa kwevalve kulawulwa kukuhlanjululwa kwe-electromagnetic. Xa ivalve ye-solenoid yonakele, kuya kubakho ukusebenza, oku kulandelayo kukusebenza okuqhelekileyo:

1. I-valve ye-solenoid ayikwazi ukuvulwa okanye ivaliwe: oku kunokuba ngenxa yomonakalo kwi-solenoid coil okanye ukuvaleka kwevalve. Ukuba i-valve ye-solenoid ayikwazi ukuvulwa okanye ivaliwe, iya kuchaphazela ukuhamba kwegesi okanye ulwelo, ngaloo ndlela ichaphazela ukusebenza okuqhelekileyo kwenkqubo yonke.

2. Isandi esingaqhelekanga esivela kwivalve yesolenoid: Xa ivalve yesolenoid yonakele, ingxolo engaqhelekanga inokukhutshwa. Oku kungenxa yentshukumo engaqhelekanga yevalve okanye ukukhuhlana phakathi kwevalve kunye negasket. Le ngxolo inokuchaphazela ukusebenza kwesiqhelo kwayo yonke inkqubo, kwaye ide ikhokelele ekusileleni kwenkqubo.

(3) Ukuvuza kwevalve ye-Solenoid okanye ukuvuza: Xa ivalve ye-solenoid ivuza okanye ivuza, ngokuqhelekileyo ngenxa yokutywinwa kakubi kwevalve okanye umonakalo wevalve. Oku kuya kubangela ukuba uxinzelelo lwenkqubo lwehle okanye ulwelo luvuze, oluya kuchaphazela ukusebenza kwesiqhelo kwenkqubo.

4. Ukufudumeza umazibuthe we-electromagnetic: Xa i-electromagnetic ishushu, idla ngokubangelwa kukugcwala kwekhoyili ye-electromagnetic okanye i-coil short circuit. Oku kunokukhokelela kubomi obufutshane be-electromagnetic kunye nomonakalo opheleleyo kwivalve ye-solenoid.

(5) Ivalve ye-solenoid ixingile okanye ixingile: Xa ivalve ye-solenoid ixingile okanye ixingile, idla ngokuba ngenxa yokukhuhlana okugqithisileyo phakathi kwevalve kunye ne-gasket okanye umonakalo wevalve. Oku kuya kubangela ukuhamba kwenkqubo ukunciphisa okanye ukuyeka ngokupheleleyo ukuhamba, ngaloo ndlela kuchaphazela ukusebenza okuqhelekileyo kwenkqubo
