The hydraulic fluid should be selected so that the operating viscosity in the operating temperature range is within the optimum range (ν opt see shaded area of the selection diagram). We recommended that the higher viscosity class be selected in each case. Example: t an ambient temperature of 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 VG 46 or VG 68; to be selected: VG 68. Note The case drain temperature, which is affected by pressure and rotational speed, can be higher than the reservoir temperature. t no point of the component may the temperature be higher than 115 C. The temperature difference specified below is to be taken into account when determining the viscosity in the bearing. If the above conditions cannot be maintained due to extreme operating parameters, please contact us.

To ensure the functional reliability of the axial piston unit, a gravimetric analysis of the hydraulic fluid is necessary to determine the amount of solid contaminant and to determine the cleanliness level according to IO cleanliness level of at least 20/18/15 is to be maintained. t very high hydraulic fluid temperatures (90 C to maximum 115 C), a cleanliness level of at least 19/17/14 according to IO 4406 is necessary. If the above levels cannot be achieved, please contact us. haft seal The FKM shaft seal may be used for case drain temperatures from -25 C to +115 C. Note For application cases below -25 C, an NBR shaft seal is required (permissible temperature range -40 C to +90 C; ordering code digit 14, K). lease contact us. Charge pump (impeller) The charge pump is a circulating pump with which the 11VLO is filled and therefore can be operated at higher rotational speeds. This also simplifies cold starting at low temperatures and high viscosity of the hydraulic fluid. n external inlet pressure increase is therefore unnecessary in most cases. Charging the reservoir with compressed air is not permissible. M Vg max Vg min M T 1 T 2 T 3 Bosch Rexroth G, RE 92510/

11 xial piston variable pump 11V(L)O series 40 ower controller 11 ower controller LR ower controller, fixed setting The power controller regulates the displacement of the pump depending on the operating pressure so that a given drive power is not exceeded at constant drive speed. The precise control with a hyperbolic control characteristic, provides an optimum utilization of available power. The operating pressure acts on a rocker via a measuring spool which moves with the control. n externally adjustable spring force counteracts this, it determines the power setting. The depressurized basic position is V g max. If the operating pressure exceeds the set spring force, the control valve will be actuated by the rocker and the pump will swivel back from the basic position V g max toward V g min. Here, the leverage at the rocker may be shortened and the operating pressure may rise in the same relation as the displacement is reduced (p B V g = constant; p B = operating pressure; V g = displacement). The hydraulic output power (characteristic LR) is influenced by the efficiency of the pump. etting range for beginning of control 50 to 350 bar.

13 xial piston variable pump 11V(L)O series 40 ower controller 13 CR ummation power-control of two power-controlled pumps, high-pressure-related override (with stop) With two pumps of the same size working in different circuits, the CR controller limits the overall power. The CR works like the normal LR with a fixed maximum power setting along the power hyperbola. The high-pressure-related override reduces the power setpoint in dependence on the operating pressure of the other pump. That happens proportionally below the beginning of control and is blocked by a stop when the minimum power is reached. Here, the CR port of the one pump has to be connected to the M port of the other pump. The maximum power of the first pump is reached when the second pump is working at idle when depressurized. When defining the maximum power, the idle power of the second pump has to be taken into account. The minimum power of each pump is reached when both pumps are working at high pressure. The minimum power usually equates to 50% of the total power. ower that is released by the pressure control or other overrides remains unconsidered. etting range for beginning of control 50 to 300 bar.

The R works like the normal LR with a fixed maximum power setting along the power hyperbola. The high-pressure-dependent override reduces the power specification in proportion to the operating pressure of the fixed pump. Here, port R of the 11V(L)O must be connected to the operating pressure of the fixed pump. The power of the controlled pump can then be reduced to zero in a borderline case. The maximum power of the controlled pump is reached when the fixed pump works at idle when depressurized. When defining the maximum power, the idle power of the fixed pump has to be taken into account. ower that is released by the pressure control or other overrides remains unconsidered. etting range for beginning of control 50 to 350 bar.

Basic position without pilot signal is V g min. This includes the mechanically depressurized basic position V g min (see ordering code digit 08). With increasing control current the pump swivels to a higher displacement (from V g min to V g max ). The necessary control fluid is taken from the operating pressure or the external control pressure applied to port. If the pump is to be adjusted from the basic position V g min or from a low operating pressure, port must be supplied with an external control pressure of at least 30 bar, maximum 50 bar.

The spring feedback in the controller is not a safety device. The controller can stick in an undefined position by internal contamination (contaminated hydraulic fluid, abrasion or residual contamination from system components). s a result, the flow of the axial piston unit will no longer respond correctly to the operator's commands. Check whether the application on your machine requires additional safety measures, in order to bring the driven consumer into a safe position (immediate stop). If necessary, make sure that these are properly implemented.

19 xial piston variable pump 11V(L)O series 40 ressure controller 19 ressure controller DR ressure controller with one-side swiveling, fixed setting The pressure controller limits the maximum pressure at the pump outlet within the control range of the variable pump. The variable pump only delivers as much hydraulic fluid as is required by the consumers. If the operating pressure exceeds the setpoint value set at the pressure valve, the pump will regulate to a smaller displacement to reduce the control differential.

20 20 11V(L)O series 40 xial piston variable pump ressure controller DR0 ressure controller with load sensing The load sensing controller works as a load-pressure controlled flow controller and adjusts the displacement of the pump to the volume required by the consumer. The flow of the pump is then dependent on the cross section of the external measuring orifice (1), which is located between the pump and the consumer. Below the setting of the pressure controller and within the control range of the pump, the flow is not dependent on the load pressure. s a rule, the measuring orifice is a separately located load sensing directional valve (control block). The position of the directional valve piston determines the opening cross section of the measuring orifice and thus the flow of the pump. The load sensing controller compares pressure before and after the measuring orifice and keeps the pressure drop (differential pressure Δp) across the orifice and therefore the flow constant. If the differential pressure Δp at the measuring orifice rises, the pump is swiveled back (toward V g min ). If the differential pressure Δp drops, the pump is swiveled out (toward V g max ) until equilibrium at the measuring orifice is restored. Hydraulic V g min stop The hydraulic V g min stop opens the valve outlet to the case drain chamber when a minimum position is reached, damping the controller and reducing overshoot. This can create a connection from high pressure or external control pressure via the controller and the hydraulic V g min stop to the case drain chamber.
