I-Excavator PC200-8 i-excavator evamile yokusiza i-valve yokusiza umzila wesitimela 6754-72-1220

1. I-valve yokuvuselela i-excavator ingasheshisa isivinini sokuwa futhi ithuthukise ukusebenza kahle komsebenzi.

2, i-valve yokuvuselela ibhakede le-excavator ifaka phakathi umkhono we-valve, ipulaki yesikulufu ixhunywe ngohlangothi olulodwa lomkhono we-valve, ikhanda le-valve lixhunywe ngakolunye uhlangothi lomkhono we-valve, kunesihlalo esingashintshi kumkhono we-valve kanye nepulaki. , ingxenye eyodwa yengxenye enwebekayo ixhunywe nesihlalo esinqunyiwe, enye ingxenye ye-valve spool sliding exhunywe nomkhono we-valve ixhunywe nomunye umkhawulo wengxenye enwebekayo, enye ingxenye ye-spool ye-valve ixhunywe nekhanda le-valve. , Faka i-plunger enoxhumano oluslayidayo maphakathi nengxenye yokugcina yekhanda le-valve elidlulela kumkhono we-valve, ingxenye yekhanda le-valve etholakala ngaphandle komkhono wevalvu inikezwa nge-radial yokuqala ngembobo, umkhawulo owodwa we-plunger uyahamba. ekupheleni kwekhanda le-valve futhi ixhumeke nenkaba ye-valve, enye iphetho ye-plunger idlulela e-radial yokuqala ngembobo, futhi i-groove eyi-annular inikezwa esiyingini se-valve core. Umkhono wevalvu uhlinzekwa nge-radial yesibili embobeni kanye ne-radial yesithathu embobeni efaniswa ne-annular groove.

I-valve yokusiza eyinhloko ifakwe emaphethelweni aphezulu naphansi e-valve yokulawula eyinhloko, eyodwa engaphezulu neyodwa ephansi. I-valve ibeka ukucindezela okukhulu ukuze lonke uhlelo lwe-hydraulic lusebenze. Lapho ingcindezi yesistimu idlula ukucindezela kwesethi ye-valve eyinhloko yokusiza, i-valve enkulu yokukhulula ivula umjikelezo kawoyela wethangi elibuyayo ukuze lichichime uwoyela we-hydraulic ubuyele ethangini ukuze uvikele lonke uhlelo lwe-hydraulic futhi ugweme ukucindezela kukawoyela ngokweqile.
