Excavator PC200-8 excavator eqhelekileyo kaloliwe ivalve yokukhulula uxinzelelo 6754-72-1220

1. I-valve yokuvuselela i-excavator inokukhawulezisa isantya sokuwa kunye nokuphucula ukusebenza kakuhle.

2, i-excavator ibhakethi intonga yokuvuselela ivalve ibandakanya umkhono wevalve, iplagi ye-screw ifakwe kwelinye icala lomkhono wevalve, intloko yevalvu idityaniswe nenye isiphelo somkhono wevalve, kukho isitulo esisisigxina kumkhono wevalve kunye neplagi. , isiphelo esinye se-elastic part sidityaniswe nesitulo esisisigxina, esinye isiphelo se-valve spool sliding sidityaniswe nomkhono wevalve sidityaniswe nesinye isiphelo se-elastic part, esinye isiphelo se-valve spool sidityaniswe nentloko yevalve. , Faka iplunger enoqhagamshelo olutyibilikayo embindini wesiphelo sentloko yevalvu ephumela kumkhono wevalve, indawo yentloko yevalvu ebekwe ngaphandle komkhono wevalve ibonelelwa ngeradial yokuqala ngomngxuma, enye isiphelo sevalve iya. kwisiphelo sentloko yevalve kwaye iqhagamshele nondoqo wevalve, esinye isiphelo se-plunger sidlulela kwi-radial yokuqala ngomngxuma, kwaye i-groove ye-annular ibonelelwe kwisangqa sombindi wevalve. Umkhono wevalvu unikwe iradial yesibini emngxunyeni kunye neradial yesithathu emngxunyeni odityaniswe ne-annular groove.

I-valve enkulu yokunceda ifakwe kwiindawo eziphezulu kunye nezisezantsi ze-valve yokulawula eyintloko, enye ephezulu kunye neyodwa ephantsi. Ivalve ibeka olona xinzelelo luphezulu kwi-hydraulic system yonke ukuba isebenze. Xa uxinzelelo lwenkqubo ludlula uxinzelelo olumiselweyo lwe-valve enkulu yokunceda, i-valve enkulu yokunceda ivula i-oil circuit ye-tank yokubuyela ukugqithisa i-oyile ye-hydraulic ibuyele kwi-tank ukukhusela yonke inkqubo ye-hydraulic kwaye ugweme ukunyanzeliswa kweoli yeoli.
