Rexroth A7V AA6VM Series Hydraulic Axial Piston Variable Tsav AA6VM80HD2 / 63W-VSC520B AA6VM80HD2 / 63W-VSC520B

Lus Cim ▶ Qhov tseem ceeb, tsis muaj kev ua tau zoo thiab kev ua siab ntev; cov nqi sib npaug ▶ Kev ua haujlwm siab tshaj qhov muaj nuj nqis siab tshaj lossis qis dua qhov tseem ceeb yuav ua rau poob haujlwm, cuam tshuam lub neej kev pab lossis kev puas tsuaj ntawm chav axialpiston. Lwm qhov kev tso cai txwv qhov tseem ceeb, xws li kev hloov pauv ceev, txo qis kev nrawm raws li kev ua haujlwm ntawm qhov zaus thiab qhov tso cai angularacceleration thaum pib (qis dua qhov siab tshaj plaws angularacceleration) tuaj yeem pom hauv cov ntaub ntawv 90261.Hydraulic fluidsThe variable motor A6VMral roj yog tsim los rau kev ua haujlwm. Raws li DIN 51524. Cov lus qhia thiab cov kev xav tau rau cov kua dej hydraulic yuav tsum tau muab los ntawm cov ntaub ntawv hauv qab no ua ntej pib qhov phiaj xwm: ▶ 90220: Cov kua dej hydraulic raws li cov roj ntxhia thiab cov hydrocarbons ▶ 90221: Environmentally txais hydraulic fluids ▶ 90222: Hluav taws kub, dej. -free hydraulic kua (HFDR / HFDU) ▶ 90223: Hluav taws kub-resistant, dej-muaj hydraulic kua (HFAE, HFAS, HFB, HFC) ▶ 90225: Axial piston units rau kev khiav hauj lwm nrog dej-free thiab dej-muaj hluav taws-resistant hydraulic kua (HFDR, HFDU, HFB, HFC).Kev lim dej ntawm hydraulic fluidFiner filtration txhim kho qib kev huv ntawm hydraulicfluid, uas ua rau kom lub neej kev pab cuam ntawm lub axial piston chav tsev.Qhov kev huv ntawm yam tsawg kawg yog 20/18/15 yog yuav tsum tau tuav tswj. mus rau ISO 4406.Thaum siab heev hydraulic kua kub (195 degree F (90 degree) siab tshaj 217 degree F (103 degree), ntsuas ntawm qhov chaw nres nkoj T), ib tug huv theem ntawm tsawg kawg yog 19/17/14 raws li ISO 4406 yog tsim nyog.

Kev cuam tshuam ntawm rooj plaub ntawm kev pib tswj Kev nce hauv cov ntaub ntawv siab muaj feem cuam tshuam rau kev pib tswj thaum siv cov kev tswj hauv qab no: ▶ HD, EP, HA, HA.T: Nce ▶ DA: Txo Nrog cov kev teeb tsa hauv qab no, nce hauv rooj plaub. siab yuav tsis cuam tshuam rau qhov pib ntawm kev tswj: HA.R thiab HA.U, EP, HA Lub Hoobkas teeb tsa ntawm qhov pib ntawm kev tswj yog tsim ntawm pabs=15 psi (1 bar) rooj plaub

Permissible siab loading Lub neej kev pab cuam ntawm lub tog raj kheej foob yog cuam tshuam los ntawm kev sib hloov ceev ntawm lub axial piston chav tsev thiab lub to nyob rau hauv lub tsev (cov ntaub ntawv siab). Momentary (t < 0.1 s) siab peaks txog li 145 psi (10 bar) tau tso cai. Cov ntaub ntawv siab ntawm qhov nruam 30 psi (2 bar) qhov siab tshaj plaws tau tso cai kom siv tau tag nrho qhov nrawm. Cov ntaub ntawv siab dua tuaj yeem tso cai ntawm qhov kev sib hloov qis (saib daim duab). Lub neej kev pab cuam ntawm cov ncej foob txo qis nrog nce zaus ntawm siab peaks thiab nce qhov sib txawv siab. Cov ntaub ntawv siab yuav tsum sib npaug los yog siab tshaj qhov siab ntawm ambient

FKM ncej foob lub nplhaib yuav siv tau rau qhov kub thiab txias ntawm -13 degree F mus rau ntxiv 240 degree F (-25 degree rau ntxiv 115 degree ). Rau cov ntawv thov hauv qab no -13 degree F (-25 degree), yuav tsum muaj NBR ncej foob (tso cai kub ntau: -40 degree F mus rau ntxiv 195 degree F (-40} degree rau ntxiv 90 degree).
