A10VO 32 Iphampu ye-Hydraulic Open circuit _Rexroth Axial piston variable Medium pressure pump
Izinsiza zokulawula
DR – Umphakathi we-pressure
Umphakathi we-ngcindezi unciphisa ingcindezi ephezulu kakhulu emaphethelweni e-pump ngaphakathi komkhawulo wokulawula we-pump eguquguqukayo.
I-pump eguquguqukayo ihlinzeka kuphela ngempahla ye-hydraulic edingekayo ngabathengi. Uma ingcindezi yokusebenza idlula inani le-oda le-ngcindezi ku-valve ye-ngcindezi, i-pump izolungisa ukuze ibe nendawo encane ukuze yehlise umehluko wokulawula.
Isikhundla esiyisisekelo esimweni sokucindezelwa: Vg max.
Uhlaka lokusetha 1) lokulawula ingcindezi 20 kuya ku-280 bar.
DRG – Umphakathi wokucindezela, ophathwa kude
Ku-pressure controller ephethwe kude, umkhawulo wokucindezela we-LS wenziwa usebenzisa i-valve yokukhulula ucindezelo ehleliwe ngokwehlukana. Ngakho-ke, noma iyiphi inani lokulawula ucindezelo ngaphansi kokucindezela okusethwe ku-pressure controller ingalawulwa. Pressure controller DR bheka ikhasi 9.
I-valve yokukhulula ingcindezi ixhunywe ngaphandle ku-port X ukuze kulawulwe kude. Le valve yokukhulula ayifakiwe emkhakheni wokulethwa kwe-DRG control.
Uhlanga lokucindezela olungu-20 bar Δp (ukusetha okujwayelekile) kuholela ekutheni kube nokugeleza kwe-oyili ye-pilot engama-1.5 l/min endaweni ye-X. Uma kudingeka ukusetha okunye (ububanzi obuphakathi kuka-10 no-22 bar) sicela uchaze ngombhalo ojwayelekile.
Njengoventil ye-pressure yokukhulula ehlukile (1) siphakamisa:
I-hydraulic noma i-electric proportional eyenziwe ngqo, efanelekile ukuze kulawulwe umoya ophakanyisiwe ngenhla.
Ubude obukhulu bomugqa akufanele budlule u-2 m.
Isikhundla esiyisisekelo esimweni sokwehliswa kwengcindezi: Vg max.
Ubungako bokusetha 1) bokulawula ucindezelo obuphakathi kuka-20 no-280 bar (3).
I-Standard ingu-280 bar.
Ibanga lokusetha le-pressure ehlukile 10 - 22 bar (2)
Standarde ingu 20 bar.
Ukukhulula iport X kuya emathunjini kuholela ekucindezelweni kokuhamba okungu-zero (ukuma) okungama-1 kuya kwama-2 bar aphezulu kune-pressure ehlongozwayo Δp, kodwa imithelela yesistimu ayithathwanga ekubhekaneni.
Standarde ingu 280 bar.
Idatha yezobuchwepheshe
Iphampu ye-medium pressure ethuthukisiwe yemishini enamandla aphezulu.
Usayizi 45 kuya ku-180.
Ing pressure ejwayelekile 280 bar.
Ing pressure enkulu 350 bar.
Umjikelezo ovulekile.
Izici
I-pump ye-displacement eguquguqukayo eneqembu le-piston elijikayo le-swashplate yokwakhiwa kwe-hydrostatic kumadivayisi avulekile.
Ukuhamba kuhlobene nesivinini sokushayela kanye nokuhamba.
Ukuphuma kungashintshwa ngaphandle kokuphela ngokulawula i-angle ye-swashplate.
I-cradle bearing ethulisiwe hydrostatically.
Iport yokuhlola isikhombisi kwiport ye-high pressure yazo zonke osayizi abaneport plate 22 no-32.
Izinga lokukhuluma eliphansi.
Ukukhuphuka kokwethembeka kokusebenza.
Ukusebenza kahle okuphezulu.
I-ratio yamandla nesisindo esihle.
Ukuhamba okujwayelekile kwe-drive kuzo zonke usayizi nge-port plate 22 no-32.
Ukunciphisa ukushaya okungakhethwa.
