4 4/48 osch Rexroth AG A10VO eries 31 RE 92711/01.12 Technical data Hydraulic fluid efore starting project planning, please refer to our data sheets RE (mineral oil) and RE (environmentally acceptable hydraulic fluids) for detailed information regarding the choice of hydraulic fluid and application conditions. When using environmentally acceptable hydraulic fluids, the limitations regarding technical data and seals must be observed. Please contact us. When ordering, indicate the hydraulic fluid that is to be used. Operating viscosity range For optimum efficiency and service life we recommend that the operating viscosity (at operating temperature) be selected in the range ν opt = opt. operating viscosity mm 2 /s referred to reservoir temperature (open circuit). imits of viscosity range For critical operating conditions the following values apply: n min = 10 mm 2 /s short-term (t 1 min) at max perm. case drain temperature of 90 C. Please also ensure that the max. case drain temperature of 90 C is not exceeded in localized areas (for instance, in the bearing area).the fluid temperature in the bearing area is approx. 5 K higher than the average case drain temperature. n max = 1000 mm 2 /s short-term (t 1 min) on cold start (p 30 bar, n 1000 rpm, t min -25 C) Depending on the installation situation, special measures are necessary at temperatures between - C and -25 C. Please contact us. For detailed information on operation with low temperatures see data sheet RE election diagram Notes on the choice of hydraulic fluid In order to select the correct hydraulic fluid, it is necessary to know the operating temperature in the reservoir (open circuit) in relation to the ambient temperature. The hydraulic fluid should be selected so that within the operating temperature range, the viscosity lies within the optimum range (ν opt ), see shaded section of the selection diagram. We recommend to select the higher viscosity grade in each case. Example: at an ambient temperature of C the operating temperature is 60 C. In the optimum operating viscosity range (ν opt ; shaded area) this corresponds to viscosity grades VG 46 resp. VG 68; VG 68 should be selected. Important: The case drain temperature is influenced by pressure and input speed and is always higher than the reservoir temperature. However, at no point in the component may the temperature exceed 90 C. The temperature difference specified on the left is to be taken into account when determining the viscosity in the bearing. If the above conditions cannot be met, due to extreme operating parameters please contact us. Filtration of the hydraulic fluid The finer the filtration the better the cleanliness level of the hydraulic fluid and the longer the service life of the axial piston unit. In order to guarantee the functional reliability of the axial piston unit it is necessary to carry out a gravimetric evaluation of the hydraulic fluid to determine the particle contamination and the cleanliness level according to IO 46. A cleanliness level of at least 20/18/15 must be maintained. At very high hydraulic fluid temperatures (90 C to maximum 115 C), a cleanliness level of at least 19/17/14 according to IO 46 is necessary. If the above cleanliness levels cannot be maintained, please contact us. Viscosity ν [mm2/s] VG VG 32 VG 68 VG 46 VG ν opt Temperature t in C t min = - C Fluid temperature range t max = +115 C

15 RE 92711/01.12 A10VO eries 31 osch Rexroth AG 15/48 ED Electro-hydraulic pressure control The ED valve is set to a certain pressure by a specified, variable solenoid current. If there is a change at the consumer (load pressure), the posi tion of the control piston changes. This causes an increase or decrease in the pump swivel angle (flow) in order to maintain the electrically set pressure level. The pump thus only delivers as much hydraulic fluid as the consumers can take. The desired pressure level can be set steplessly by varying the solenoid current. When the solenoid current signal drops towards a zero value, the maximum output pressure is limited to p max by an adjustable hydraulic pressure cut-off (secure fail safe function in case of a loss of power e.g. for use as fan drives). The response time characteristic of the ED-control was optimized for the use as a fan drive system. When ordering, state the type of application in clear text.
