R210-7 R220-3 Ivalve yokunceda i-Excavator XJBN-00653 hydraulic valve

Emva kokuba i-injector ifakwe kwintloko ye-cylinder, i-O-ring ephakathi kwi-O-rings emithathu ihlukanisa i-oyile ye-oyile kwintloko ye-cylinder kwi-oil inlet passage kunye ne-oyile yokubuyisela i-oyile (inxalenye ephezulu yindlela yokubuyisela ioli). Ngenxa yokuba uxinzelelo lweoyile yendlela yokungenisa ioyile iphezulu kunendlela yokubuya kweoyile, xa i-O-ring ephakathi yaphukile, ioyile ekwindlela yokungena yeoli iya kuvuza kwipaseji yokubuyisela ioyile, ngaloo ndlela inyusa uxinzelelo kwioyile. indlela yokubuya. Xa ucimo lucinyiwe, uxinzelelo kwipaseji yeoyile yokubuya iya kubuyiselwa kwipaseji yeoli yokungena, ukuze uxinzelelo lweoyile phambi komngxuma wokumitha wenaliti ungancitshiswa kwangethuba kwidangatye ngaphandle koxinzelelo lweoyile, okukhokelela kubunzima bomlilo. . Ubunzima bomonakalo we-O-ring buhluka kunye nexesha elide kunye nelifutshane lomlilo. Emva kokuba iphoso lenzeka, kunzima ukucacisa ukuba yeyiphi i-cylinder ye-injector ephakathi kwe-O-ring yonakaliswe, kwaye kuyimfuneko ukukhupha ngokuthe ngcembe i-injector ukuze ihlolwe de kufumaneke isizathu. Xa utshintsha i-O-ring eyonakalisiweyo, i-O-ring kufuneka ifakwe ngokuchanekileyo kwi-injector groove kwaye ayikwazi ukujijwa; Kufuneka ifakwe ngeoli ngaphambi kokulayisha intloko yesilinda; Ekubeni i-injector ikhutshwe kwaye ilayishwe kwakhona, ngokubanzi, ukuba akukho mlinganiselo okhuselekileyo kakhulu, i-plunger stroke ye-injector kufuneka ihlaziywe kwakhona.
