5 RE 92800/03.10 A15VSO Series 10 Bosch Rexroth AG 5/32 Technical data Hydraulic fluid For extensive information on the selection of hydraulic fluids and application conditions consult our data sheet RE (mineral oil). The variable pump A15VSO has been released for operation on mineral oils. For operation on ecologically acceptable fluids or HF-fluids please consult us. When ordering please state the fluid to be used. Selection diagram Viscosity ν in mm 2 /s VG 22 VG 32 VG 46 VG 68 VG ν opt Notes on the selection of hydraulic fluids In order to select the correct fluid, it is necessary to know the operating temperature in relation to the ambient temperature: in an open circuit the tank 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 in the selection diagram. We recommend, that the higher viscosity grade is selected in each case. Example: at an ambient temperature of X C the operating temperature in the tank is 60 C. In the optimum viscosity range (ν opt ; shaded area), this corresponds to grades VG 46 or VG 68; select: VG 68. Important The case drain temperature is influenced by pressure and speed, and is always higher than the tank temperature. At no point in the system may the temperature be higher than 110 C, however. For the viscosity conditions in the bearing area, the temperature difference as stated below must be observed. If the above conditions, due to extreme operating parameters cannot be met, please consult us Temperature t in C t min = -40 C Fluid temperature range t max = +115 C Viscosity and temperatue Viscosity [mm 2 /s] Temperature Remark Transport + storage T min -50 C T opt = +5 C to +20 C to 12 months with factory made preservation to 24 months with factory made long-time preservation (Cold) Start 1) n max = 1600 T St -40 C t 3 min, light load (20 bar 50 bar), n 1000 rpm permissible temperature DT 25 K between axial piston unit and fluid difference Warm-up phase n = 1600 to 400 T = -40 C to -25 C at p nom, 0.5 n nom and t 15 min Operating phase Temperature difference DT = ca. 5 K Continuous operation n = 400 to 10 T = -25 C to + 90 C n opt = 16 to 36 Short-time operation n min = 5 T max = +115 C t < 3 min, p < 0.3 p nom Shaft seal FKM 1) T +115 C see page 6 The fluid temperature in the bearing area (influenced by pressure and speed) is approx. 5 K higher than the case drain fluid at port T. no restriction within the permissible data 1) At temperatures below -25 C a NBR shaft seal is necessary (permissible temperature range: -40 C to +90 C)

6 6/32 Bosch Rexroth AG A15VSO Series 10 RE 92800/03.10 Technical data Filtration The finer the filtration, the better the achieved cleanliness of the fluid and the longer the life of the axial piston unit. In order to guarantee a reliable function of the axial piston unit it is necessary to carry out a gravimetric evaluation of the fluid to determine the particle contamination and the cleanliness class to ISO A minimum cleanliness class of 20/18/15 is necessary. At very high fluid temperatures (90 C to maximum 115 C) a cleanliness class of at least 19/17/14 to ISO 4406 is required. Case drain pressure The case drain pressure at ports T 1 to T 3 may not be higher than max. 1.2 bar above the inlet pressure at port S, however in any case not higher than p L abs. max 4 bar. A case drain line to the tank is required. Temperature range of the shaft seal The FKM (fluor-caoutchouc) shaft seal is permissible for fluid temperatures of -25 C to +115 C. Note For applications below -25 C a NBR (nitrile rubber) shaft seal is required (permissible temperature range: -40 C to +90 C). Please state in clear text NBR shaft seal when ordering. Please consult us.

10 10/32 Bosch Rexroth AG A15VSO Series 10 RE 92800/03.10 Power control LR Power control The power control adjusts the pump displacement in relation to the operating pressure in such a manner, that a given drive power at constant drive speed is not exceeded. p B = Operating pressure p B V g = konstant V g = Displacement This precise control along the hyperbolic control characteristic permits an optimum utilisation of drive power. The operating pressure acts on a lever mechanism via the measuring spool, which moves along with the displacement control mechanism. It is offset by an externally set spring force which determines the power setting. The pressureless initial position is V g max. When the operating pressure exceeds the set spring force, the power control pilot valve is actuated via the lever mechanism and the pump swivels from the initial position V g max back to a smaller displacement V g min. This in turn reduces the effective moment on the lever mechanism and the operating pressure can increase in the same ratio by which the pump displacement is reduced (p B V g = constant). The hydraulic output power (control curve LR) is influenced by pump efficiency. Please state in clear text when ordering: Drive power P in kw Drive speed n in rpm Max. flow qv max in L/min After clarification of the details we can compute a suitable power control characteristic.

12 12/32 Bosch Rexroth AG A15VSO Series 10 RE 92800/03.10 Displacement control E2 Electro proportional override The electric displacement control with a proportional solenoid adjusts the pump displacement stepless and proportional to the current via the solenoid force. Initial position without current signal is V g min ; this corresponds with the mechanical pressureless initial position V g min (see type code 08). Adjustment with increasing current signal from V g min to V g max With increasing control current the pump swivels to a larger displacement. The necessary control fluid is taken out of the pump outlet pressure side or from an external control pressure supply to port P. In order to bring the pump at low output pressure out of it s initial center position it is necessary to supply an external control pressure of at least 30 bar, but not more than 50 bar to port P. Note: Without the supply of external control pressure to P it is necessary to order the execution "Maximum swivel angle (V g max ), without external control pressure supply (see type code pos. 08, A). Important: Mounting of a pump with E.-control inside the reservoir is only permitted when using mineral hydraulic fluid with a temperature of maximum 80 C.

15 CR PR CR PR RE 92800/03.10 A15VSO Series 10 Bosch Rexroth AG 15/32 Pressure control DRS0 Pressure control with Load-Sensing The Load-Sensing controller operates as a load pressure independent flow control and adapts the pump displacement to the actual required M A A Pflow at the consumer. The pump flow depends here on the cross section of a measuring orifice (1), installed between pump and hydraulic consumer. Below the pressure control setting and within the control range of the pump the flow is independent of the load pressure. The measuring orifice is normally a Load-Sensing directional valve (Valve block). The valve spool position determines the size of the cross section opening and thereby the pump flow. S M S M T 1 T 2 T 3 The Load-Sensing-controller compares the pressures upstream and downstream of the measuring orifice and keeps the pressure drop (differential pressure p) and thus the corresponding flow constant. An increase of the differential pressure p at the measuring orifice causes the pump to destroke DR (towards V g min ), and a decrease of the p causes the pump to swivel to a higher displacement (towards V g max ), till the balance at the measuring orifice has been restored. p measuring orifice = p pump p consumer Setting range for p 14 to 30 bar (please state in clear text). Standard setting 14 bar The stand-by pressue at pump center position (measuring orifice closed) is a bit higher than the p-setting.

29 RE 92800/03.10 A15VSO Series 10 Bosch Rexroth AG 29/32 Plugs for solenoids HIRSCHMANN DIN EN A/ISO 4400 Without suppressor diode H Protection to DIN/EN 60529: IP65 together with a mating plug (2) (1) ø Changing the plug orientation If needed, the orientation of the plug can be altered by turning of the solenoid body. To do this, proceed as follows: 1. Loosening the solenoid fixing nut (1). 2. Bringing the solenoid body (2) into the desired orientation. 3. Re-tightening of the solenoid fixing nut. Tightening torque: 5 ±1 Nm (Width across the flats 26mm, 12 point DIN 3124). Upon delivery it is possible that the solenoid orientation is not as shown on the drawing or in the data sheet.

30 30/32 Bosch Rexroth AG A15VSO Series 10 RE 92800/03.10 Installation notes General The axial piston unit must be filled with fluid and deaerated during commissioning and operation. This is also important after prolonged periods of standstill, since the system can empty itself via the hydraulic lines (mounting above the reservoir). The case drain fluid must be discharged to tank via the highest positioned one of the tank connections (T 1, T 2, T 3 ). The minimum inlet pressure at suction port S may not fall below 0.8 bar absolute. (At cold start 0.5 bar absolute). Under any operating conditions the suction and tank lines must enter the reservoir below the minimum fluid level. Mounting position See examples below. Further mounting positions are possible; please consult us. Recommended mounting position: 1 and 2. Mounting below the reservoir (Standard) Pump below the minimum reservoir fluid level. Mounting above the reservoir Pump above the minimum reservoir fluid level. Observe the maximum permissible suction height h s max = 800 mm. Recommendation for mounting position 5 (drive shaft upwards): A check valve in the case drain line to tank (cracking pressure 0.5 bar) can prevent the housing chamber from running empty. 1 2 F F 4 5 F F ht min h t min 200 mm SB 200 mm hmin h min 100 mm amin 100 mm T T 1 1 T 2 T 3 T 2 S 3 F T 2 h t min 200 mm h min 100 mm S SB a min T 3 S SB a min 6 T 2 T 3 T 2 S h S max 800 mm h t min 200 mm h min 100 mm F T 1 S SB a min h S max 800 mm h t min 200 mm h min 100 mm 0.5 bar T 2 S T 3 SB a min T 1 T 1 T 3 T 1 h t min 200 mm h min 100 mm T 3 h S max 800 mm SB a min Mounting position Bleeding Filling Mounting position Bleeding Filling 1 T 1 S + T 1 (F) 4 F T 1 (F) 2 T 2 S + T 2 (F) 5 F T 2 (F) 3 T 2 S + T 2 (F) 6 F T 2 (F) h s max = 800 mm, h t min = 200 mm, h min = 100 mm, SB = Baffle (wash plate) Provide sufficient distance a min between the suction line and case drain line during design of the reservoir.

32 32/32 Bosch Rexroth AG A15VSO Series 10 RE 92800/03.10 General instructions The pump A15VSO was designed for operation in open loop circuits. Systems design, installation and commissioning of the axial piston unit require trained technicians or tradesmen. Before operating the axial piston unit make sure to read the relevant operating manuel carefully and completely. If needed, request this information from Rexroth. All hydraulic ports can only be used for the fastening of hydraulic service lines. During and shortly after operation of a pump the housing and especially a solenoid can be extremely hot, avoid being burned; take suitable safety measures (wear protective clothing). Dependent on the operating conditions of the axial piston pump (operating pressure, fluid temperature) deviations in the performance curves can occur. Pressure ports: All materials and port threads are selected and designed in such a manner, that they can withstand the peak pressures. The machine and system manufacturer must ensure, that all connecting elements and hydraulic lines are suitable for the actual operating conditions (pressures, flow, fluid, temperature) in accordance with the necessary safety factors. All given data and information must be adhered to. The following tightening torques are valid: --Female threads in the axial piston unit: the maximum permissible tightening torques M G max are maximum values for the female threads in the pump casting and may not be exceeded. For values see table below. --Fittings: please comply with the manufacturer s information regarding the max. permissible tightening torques for the used fittings. --Fastening bolts: for fastening bolts to DIN 13 we recommend to check the permissible tightening torques in each individual case to VDI Plugs: for the metal plugs, supplied with the axial piston unit the following min. required tightening torques M V apply (see table) The product has not been released as a component in the safety concept of a total machine system acc. to DIN EN ISO Ports Standard Thread size Max. perm. tightening torque for female threadsm G max Min. required tightening torque for plugs M V ISO ) M14 x Nm 45 Nm 6 mm M42 x Nm 330 Nm 22 mm 2) 1) The spot face can be deeper than specified in the appropriate standard. 2) Deviating from ISO 6149 Across the flats in socket of Allan head screw Bosch Rexroth AG Hydraulics Axial Piston Units An den Kelterwiesen Horb, Germany Telefon +49 (0) Telefax +49 (0) info.brm-ak@boschrexroth.de This document, as well as the data, specifications and other information set forth in it, are the exclusive property of Bosch Rexroth AG.
