I-Bosch Rexroth Axial piston variable displacement double pump A8VO
Izici
I-pump ye-variable displacement dual enezinhlaka ezimbili ze-axial cone-type piston ezijolise ekwakhiweni kwe-swash plate, eyenzelwe ukudluliswa kwe-hydrostatic okukhululekile. Izinga lokugeleza lishintsha ngokulinganayo ngesivinini sokufaka kanye nokukhishwa, linikeza ukuguquguquka okungapheli ukusuka ku-Qv max kuya ku-Qv min(0). Ikhono lokufaka ngqo kumaflanga e-diesel engine. I-charge pump ehlanganisiwe enendawo yokudonsa eyabelwe yokusebenza kwe-circuit ezimbili. Ama-algorithms wokulawula athuthukile avumela izindlela eziningi zokulawula (uk pressure/flow/power control). Umphakathi wokulawula amandla okukhawulela ozimele ukuze kuthuthukiswe ukuphathwa kwamandla. I-charge pump eyakhelwe ngaphakathi enevavavu yokukhulula ingcindezi, ivavavu yokunciphisa ingcindezi eyengeziwe ethokozisayo. Izilungiselelo eziningi ze-PTO zikhona zokufaka ama-piston e-axial nama-gear pumps. I-ratio yamandla kuya kwesisindo ehamba phambili embonini yokufaka okuncane. Ikhishiwe ukuze ihlale isikhathi eside ngaphansi kwezimo zokusebenza eziyingozi.
Amafutha e-hydraulic
Ngaphambi kokuthi uqale ukuhlela iphrojekthi yakho, sicela ubheke amakhasi ethu edatha yobuchwepheshe RC 90220
(amafutha emaminerali), RC 90221 (amafutha e-hydraulic angokwemvelo) kanye ne-RC 90223 (HF hydraulic
amafutha) ukuze uthole ulwazi olunembile mayelana nokukhetha amafutha e-hydraulic nezimo zokusebenza.
Ama-pump amabili e-A8VO anokushintsha okungaguquki awafaneleki ukusetshenziswa ne-HFA. Uma i-HFB, i-HFC kanye ne-
I-HFD noma ama-hydraulic oils ahlanzekile asetshenziswa, imikhawulo kumapharamitha wezobuchwepheshe nezikhwama ku-RC 90221 nase-RC 90223 kumele ilandelwe.
Uma u-oda, sicela uchaze amafutha e-hydraulic asetshenzisiwe.
Qaphela:
Izinga lokushisa lokuphuma kwecala (elithinteka ngengcindezi ngebhande) lihlala liphezulu kunokulawula noma izinga lokushisa lethangi. Izinga lokushisa akufanele lidlule ku-115 ºC kunoma yisiphi isikhathi ohlelweni.
Uma lezi zimo zingahlangatshezwana ngenxa yezimo zokusebenza ezinzima, sicela uxhumane nathi
Ukuhlunga
Ukuthi ukuhluza kube kuhle, izinga lokuhlanzeka le-hydraulic fluid liphakeme futhi impilo yesevisi ye-axial piston unit ibe yinde.
Ukuze uqinisekise ukuhambisana kokusebenza kwedivayisi ye-axial piston, izinga lokuhlanzeka le-hydraulic fluid kufanele libe okungenani
20/18/15 ngokwe-ISO 4406.
Ezingeni eliphezulu kakhulu lokushisa kwamafutha (90 ºC kuya ku-115 ºC), izinga lokuhlanzeka kufanele libe okungenani
19/17/14 ngokwe-ISO 4406.
Uma lezi zinga ezingaphezulu zingahlangatshezwa, sicela uxhumane nathi.
