I-Bosch Rexroth Axial piston variable displacement double pump A8VO

Izici

Iphampu ye-variable displacement dual enezinhlaka ezimbili ze-piston ezijikelezayo ezine-cone-type ezine-swash plate design, eyenzelwe ukudluliswa kwe-hydrostatic okukhululekile. I-Flow rate ilungiswa ngokulinganayo ngesivinini sokufaka kanye nokukhishwa, inikeza ukwehluka okungapheli ukusuka ku-Qv max kuya ku-Qv min(0). Ikhono lokufaka ngqo kumaflywheel e-diesel engine. Iphampu ye-charge 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 kuqinisekiswe ukuphathwa kwamandla okuphumelelayo. Iphampu ye-charge eyakhelwe ngaphakathi enevavhu yokukhulula ingcindezi, ivavhu yokunciphisa ingcindezi eyengeziwe ethokozisayo. Izilungiselelo eziningi ze-PTO zikhona zokufaka ama-piston axials kanye nezimpampu ze-gear. I-ratio yamandla kuya kwesisindo ehamba phambili embonini yokufaka okuncane. Yakhelwe ukuphila okude kokusebenza ngaphansi kwezimo ezinzima zokusebenza.

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 imininingwane ethile mayelana nokukhetha amafutha e-hydraulic nezimo zokusebenza.

Ama-pump amabili e-A8VO angashintsha akufanele asetshenziswe ne-HFA. Uma i-HFB, i-HFC kanye ne-
I-HFD noma ama-hydraulic oils ahlanzekile asetshenziswa, imikhawulo kumapharamitha wezobuchwepheshe kanye nezivalo ku-RC 90221 nase-RC 90223 kumele ilandelwe.
Uma u-oda, sicela uchaze amafutha e-hydraulic asetshenzisiwe.

Qaphela:
Izinga lokushisa lokuphuma kwecala (elithinteka ngengcindezi kanye nesivinini) lihlala liphezulu kunezinga lokushisa lokulawula noma lethangi. Izinga lokushisa akufanele lidlule ku-115 ºC kunoma yisiphi isikhala ohlelweni.
Uma lezi zimo zingahlangatshezwana ngenxa yezimo zokusebenza ezinzima, sicela uxhumane nathi

Ukuhlunga
Ukuthi uma kuhlanzwa kahle, izinga lokuhlanzeka le-hydraulic fluid liphakeme futhi isikhathi sokusebenza kwe-unit ye-axial piston siba side.
Ukuze uqinisekise ukuhambisana kokusebenza kwe-unit 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.
