4/36 Bosch exroth A Moile Hydraulics A10V E 92 750/06.04 Technical Data Fluid Before starting a project, get detailed information aout the selection of pressure fl uids and application conditions from our catalog sheets E 90220 (mineral oil), E 90221 (environmentally acceptale hydraulic fl uids) and E 90223 (fi re resistant hydraulic fl uids, HF). The variale displacement pump A10V is unsuitale for operation with HFA, HFB and HFC. For operation with HFD or environmentally acceptale hydraulic fl uids, restrictions in the technical data and seal selection must e noted; inquire if necessary (please state the hydraulic fl uid to e used in plain text in the order). Operating viscosity range For optimum effi ciency and service life, select an operating viscosity (at operating temperature) within the optimum range of ν opt = opt. operating viscosity 16...36 mm 2 /s depending on the circuit temperature (closed circuit). Limits of viscosity range The limiting values for viscosity are as follows: ν min = 5 mm 2 /s short term (t < 3 min) at max. perm. temperature of t max = +115 C. Note that the max. hydraulic fl uid temperature of 115 C may not e exceeded even locally (e.g. in the earing area). ν max = 1600 mm 2 /s short term (t < 3 min) at cold start (p 30 ar, n 1000 rpm, t min = -40 C). Only for starting up without load. Optimum operating viscosity must e reached within approx. 15 minutes. pecial measures are necessary in the temperature range from -40 C to -25 C, please contact us. For detailed information aout use at low temperatures, see E 90300-03-B. Notes on the selection of the hydraulic fluid To choose the correct hydraulic fl uid, it is necessary to know the operating temperature in the circuit (closed circuit), depending on the amient temperature. The hydraulic fl uid should e selected so that the operating viscosity is in the optimum range (ν opt ) in the operating temperature range, see selection diagram, shaded area. We recommend choosing the higher viscosity class. Example: At an amient temperature of X C an operating temperature of 60 C is set in the circuit. In the optimum operating viscosity range (ν opt ; shaded area) this corresponds to the viscosity classes V 46 or V 68; choose: V 68. Important: The leakage oil (case drain oil) temperature is infl u- enced y pressure and pump speed and is always higher than the circuit temperature. However, the temperature must not exceed 115 C at any point in the circuit. If the aove conditions cannot e satisfi ed in the case of extreme operating parameters or high amient temperatures, please contact us. election diagram Viscosity ν in mm 2 /s 2500-40 -20 0 20 40 60 80 100 1600 1000 600 400 200 100 60 40 20 10 V 22 V 32 V 68 V 46 V 100 1600 36 16 ν opt. 5 5-40 -25-10 0 10 30 50 70 90 115 Temperature t in C t min = -40 C Hydraulic fl uid temperature range t max = +115 C
E 92 750/06.04 A10V Moile Hydraulics Bosch exroth A 5/36 Technical Data Filtration The fi ner the fi ltration, the higher the cleanliness class of the hydraulic fl uid and the longer the life of the axial piston unit. To ensure functional reliaility of the axial piston unit at least cleanliness class 20/18/15 to IO 4406 is necessary. Depending on the system and the application, for the A10V we recommend fi lter elements β 20 100 With a rising pressure differential at the fi lter element, the β-value must not deteriorate. At very high hydraulic fl uid temperatures (90 C to max. 115 C) at least cleanliness class 19/17/14 to IO 4406 is necessary. If the aove classes cannot e oserved, please contact us. For notes on fi ltration types, see page 32. haft seal temperature range The FKM shaft seal ring is permissile for housing temperatures of -25 C to +115 C. Note: For applications elow -25 C, an NB shaft seal is necessary (permissile temperature range: -40 C to +90 C). Please state NB shaft seal in plain text when ordering Case drain pressure The lower the speed and the case drain pressure, the longer the service life of the shaft seal ring. The values shown in the diagram are permitted maximum values for a shaft seal ring under intermittent pressure and must not e exceeded. tationary pressure loads within the range of the maximum permitted leakage pressure may reduce the service life of the shaft seal ring.

10/36 Bosch exroth A Moile Hydraulics A10V E 92 750/06.04 DA - Hydraulic Control, peed elated The DA control is an engine speed-dependent, or automotive, type control system. The uilt-in DA regulating cartridge generates a pilot pressure that is proportional to pump (engine) drive speed. This pilot pressure is directed to the positioning cylinder of the pump y a solenoid actuated 4/3 way directional valve. Pump displacement is infi nitely variale in each direction of fl ow, and is infl uenced y oth pump drive speed and discharge pressure. Flow direction (i.e. machine forward or reverse) is controlled y energizing solenoid a or. Increasing pump drive speed generates a higher pilot pressure from the DA cartridge, with a susequent increase in pump fl ow and/or pressure. Dependent on the selected pump operating characteristics, increasing system pressure (i.e. machine load) causes the pump to swivel ack towards a smaller displacement. Engine overload (anti-stall) protection is achieved y the comination of this pressure-related pump de-stroking, and the reduction of pilot pressure as the engine speed drops. Any additional power requirement, such as implement hydraulics, may result in further engine pull down. This causes a further reduction in pilot pressure and therefore pump displacement. Automatic power division and full utilization of availale power is thus achived for oth the vehicle transmission and the implement hydraulics, with priority given to the implement hydraulics. To provide controllale reduced vehicle speed operation when high engine speeds are required for fast implement hydraulics, various inching options are availale. The DA regulating cartridge can also e used in pumps with conventional control devices, such as EP, HW or HD, to provide an engine anti-stall function, or as a comination of automotive and displacement control functions. Application of the DA control is only appropriate on certain types of vehicle drive systems, and requires a review of the engine and vehicle parameters to ensure proper application of the pump, and safe and effi cient machine operation. All DA applications must therefore e reviewed y a exroth Application Engineer.

The valves will e set to this value if the differential pressure is not specifi ed on ordering. For the sake of simplicity: The ypass function is not shown in the circuit diagrams The pressure cut-off corresponds to a pressure regulation which, after reaching the set pressure, adjusts the displacement volume of the pump to Vg 0 = 0. This valve prevents the operation of the high pressure relief valves when accelerating or decelerating. The pressure peaks occurring when the swashplate is swiveled rapidly and also the maximum pressure in the system are maintained y the high pressure relief valves. The setting range of the pressure cut-off may e anywhere within the entire operating pressure range. However,it must e set 30 ar lower than the setting of the high pressure safety relief valves (see setting diagram). Please state the setting value of the pressure cut-off in plain text when ordering.
