I-Excavator EX200-5 ivalve enkulu yokusiza iphampu I-Hydraulic distribution valve YA00011313

I-excavator ye-Hitachi igubha ukulungisa amaphutha angenawo amandla
Iphampu ye-hydraulic ye-excavator ye-Hitachi iyiphampu eguquguqukayo ye-plunger. Lapho usebenza isikhathi esithile, izingxenye zepompo ye-hydraulic, njenge-cylinder block, i-plunger, i-valve plate, i-swing, njll., nakanjani zizokhiqiza ukuguga ngokweqile, okuholela ekuvuzeni okukhulu kwangaphakathi kanye nedatha yepharamitha engahlanganisiwe. , okubangela ukugeleza okwanele nokushisa okuphezulu kwamafutha, isivinini esincane, nokungakwazi ukusungula ukucindezela okuphezulu, ngakho-ke isenzo sihamba kancane futhi ukumba kubuthakathaka. Ngezinkinga ezinjalo, kuyadingeka ukususa iphampu ye-hydraulic, ukuyithumela emnyangweni wokulungisa iphutha, hlola idatha yepompo ye-hydraulic, uqinisekise inkinga ye-excavator, esikhundleni sezingxenye ezingasakwazi ukusetshenziswa, ukulungisa izingxenye ezingasetshenziswa. , hlanganisa kabusha iphampu ye-hydraulic, bese uya ebhentshini lokuhlola lokususa iphutha ukuze ufanise uchungechunge oluhlukahlukene lwamapharamitha athambile (njengokucindezela, ukugeleza, i-torque, amandla, njll.).

I-Hitachi excavator ye-hydraulic yasekuqaleni yokusabalalisa i-valve yokusabalalisa i-valve yezindlela eziningi ngaphezu kwe-valve yokuphepha eyinhloko, i-valve yesibili, i-jet valve, i-valve kawoyela nokunye. Uma lezi zivalo zokuphepha okwamanje zingasethelwe ekucindezelweni okujwayelekile (ukucindezela okujwayelekile kwe-valve eyinhloko yokuphepha ye-EX200-5 yi-320kg, kodwa ukucindezela kwamanje kungu-230kg kuphela), ukumba kuzoba buthakathaka. Ukwengeza, uma igebe phakathi kwesiqu se-valve kanye nembobo ye-valve inkulu kakhulu ngenxa yokuguga, ukubuya kwe-valve stem akuphelele, okuholela ekugelezeni okunganele kanye nesivinini esincane. Ngezinkinga ezinjalo, kuyadingeka ukususa i-valve yokusabalalisa yezindlela eziningi, ukuyithumela enkampanini ngokuqondile endaweni yokulungisa iphutha yokulungisa iphutha, ukusetha kabusha ukucindezela kwawo wonke ama-valve okuphepha, nokuqeda igebe phakathi kwesiqu se-valve kanye nomgodi we-valve.
