Seriously Adrian, when EV3 is closed the pump will be trying to swivel to max as hard as it can. I wouldn’t normally be so insistent, but they way I have explained it really is the way it works. Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their a1v0so.

People come here for advice and if we gave the wrong advice then that would be no good at all. The Eng-Tips staff will check this out and take appropriate action. The pump part number and controller matches what is shown on the drawing.

Number of Employees 11 to 25 People. The spring of the controller now again tries to increase the flow but the resultant pressure drop again reduces the flow.


It is not directly changing the flow, just the pressure. Sure it acts as a backup like Bumblyari says but that may not be the only reason that it is there. Cookie which makes possible to choose the currency you would like.

The proportional pressure relief valve Item 2 opens at the set pressure. Our inhouse brand ROBUST delivers many products such as hydraulic and pneumatic fittings in steel, brass and stainless steel.


Even though the pump supplier’s description that matches the schematic diagram, that also describes the operation as being flow and pressure control, with power limiting My question is how power control is taking place in the circuit? Year of Establishment It is usually around – kPa. So, in order maintain the pressure drop, the pump will increase or decrease the flow rate.

A10VSO Variable displacement pump power control drawing is the drawing of a pump with power regulation. View Contact Call Seller Now. Table of Values Size Bumblyari is quite correct, it is a subtle adaptation of a load sensing compensator to give power limiting. It’s a power limiting pump with a load sense compensator.

It could like 73lafuite suggested, it is simply running on high power for a short period a10cso time.

Hello, You are right, the proportional valve 2 thus limits the maximum pressure force up to tons. Sorry but I beg to differ. Jacc’s got it just about right. An orifice to provide a pressure differential is indeed the core of a Load Sensing principle. It features fast control response, and its through- shaft design allows it to be used in multiple hydraulic circuit systems.

The delta pressure at the compensator will be the same as the pressure drop across the orifice. The manually adjusted cut-off compensator performs a similar back-up function for the proportionally adjusted one ie.

Those may be the damping orifices just to the left of the left-hand compensator but the resolution of the diagram isn’t really good enough to say. We also service all kinds of pumps and most of the valves especially those of Bosch Rexroth and Moog. The margin compensator controls the pump angle to set flow. Limiting the flow will drive the upstream pressure up and that is pointless.
