I think maybe the person who wrote the manual was in a hurry.

Do you have a closed loop electronic control which measures the intensity of the electric motor or the pressure multiplied by the speed of the cylinder? The margin compensator controls the pump angle to set flow. Power will be automatically controlled if we can control the flow dynamically.

Can you confirm that power control is taking place? Could you give me details on this phenomenon? As the control piston extends to de-stroke the pump it also increases the pressure setting of this pilot relief usually a dual spring arrangement to approximate to a hyperbolic constant power curve. A10cso is proportional to drive speed and displacement.

When you first start the pump, the pressure at the outlet is what the load sense compensator is set to. On mobile machines with LS system the pressure out to cylinder from a certain directional control valve is sometimes limited to a lower setting on some Caterpillar machines also maybe? As drawn the system gives Power, Pressure and Flow Control.


The manually adjusted cut-off compensator performs a a10veo back-up function for the proportionally adjusted one ie. But physically see the image attached it is NOT a power control pump.

You’ll agree once you understand how a load sensing pump works”. This is not a mobile LS valve, it’s not about regulating the flow across that 1mm orifice. People come here for advice and if we gave the wrong advice then that would be no good at all. Download Now White Paper: This is a standard method of achieving remote or proportional pressure limiting when the pump doesn’t have a two-stage compensator.

Basically it is the same as having an infinitely large orifice in the line of flow, the pump will never be able to deliver enough flow to reach the pressure differential that is set in the pump controller margin pressure. Now can you explain me just as I did in the DRS control how this is happening with a proportional relief valve.


For axial piston units with swashplate design, the pistons are arranged axially with respect to the drive shaft. That controller is not visible on the pictures, which makes me think that the pump may have been swapped. There is no load sense line coming from the press cylinder and when EV3 is energised there is nothing between the pump and the press cylinder other than a straight-through piece of pipe, so no flow control.


The flow from the pump is directed to the actuators, but the pump control remains independent of the load at the actuators. Number of Employees 11 to 25 People. I agree to the terms and privacy policy. A10VSO Variable displacement pump power control You keep saying that the proportional relief valve is to limit the pressure.

It’s essentially a load sensing system with a power limiter on top. I guess it would be possible to use something similar in the PLC? Statistic cookies help website owners to understand how visitors interact with websites by collecting and reporting information anonymously. Usually but not always an increase in pressure will increase the flow.

The power limiting is achieved with the pilot relief valve closest to the pump.

The point at which the pump flow rate will a10vsl to reduce is therefore determined by the setting of the proportional relief valve provided it is set lower than the load pressure. You just have to imagine that the variable orifice in the line of flow is not there or just pu,p open all the time. The 1mm not 6. Viewing it like a pressure relief on an LS line makes more sense, the prop.
