Why is there an LS-spool to start with, why not just a pressure compensator spool?

Since it is an electrical proportional relief valve the pressure can be controlled at any time. As an example, simply connecting the LS port to the P port of an LS pump will force the pump up to maximum flow. Hydraulic variable pumps in axial piston swashplate design for hydrostatic drives in an open circuit. It may help to supply some pictures of the other other side of the pump. It’s not worth arguing about, it’s educational The spring of the controller now again tries to increase the flow but the resultant pressure drop again reduces the flow.

Can you confirm that power control is taking place? pkmp

Yes, the valve can and does control the flow across the orifice. That controller is not visible on the pictures, which makes me think that the pump may have been swapped. A10VSO Variable pimp pump power control I agree that the load sense pump in the picture does not appear to be the same as the power limiting one pumpp the circuit.

Get best deals for coconut. I found a document of Parker, explaining the same load sense control in each stage. I agree with your explanation. In this case it is a hydraulic press, accurate control of speed and position is not so important, the important thing is to control is pressure. So, in order maintain the pressure drop, the pump will increase or decrease the flow rate. Register now while it’s still free! It is only the fact that we make so many machines with this sort of control that means I can spot the difference.

Flow is proportional to drive speed and displacement. You probably know very well how a pressure relief on a LS line work.

Close this window and log in. Now as Adrian says, the manufacturer has adapted the control to work like a power control.

A10V(S)O variable piston pump – Rexroth

Nature of Business Manufacturer. A10VSO Variable displacement pump power control The pump part number and controller matches what is shown on the drawing. As drawn the system gives Power, Pressure and Flow Control.

With this subtle difference as shown above, the speed is fixed and so the flow can be changed by changing the pressure drop across the orifce. Of course the orifice is there to limit the flow as Jacc rightly says. Actually, I’m in England.

The way pump pressure and flow control systems work are not similar, they are fundamentally different.

When valve EV3 opens to move the press, the pump outlet pressure would drop and oil would start to flow, but while the delta pressure over the 1mm orifice is higher than the margin compensator setting, the pump flow will remain low. We also service all kinds of pumps and most of the valves especially those of Bosch Rexroth and Moog. The flow can be steplessly changed by adjusting the swashplate.

This keeps on happening the flow gets reduced until the pressure pumpp is equal to the spring setting of the DRS control. And so I strongly would be interested to understand how you make the other side of the Atlantic Ocean to use pumps without power control. In this case BAR, which happens to be max working pressure of the A10 pumps.

Promoting, selling, recruiting, coursework and thesis posting is forbidden. It would also help to know the stand by pressure of the pump Adrian. This is how this system is connected as well with the addition of a proportional pressure relief valve on the LS signal line. But, in this circuit, how is flow being dynamically reduced with the rise is pressure so as to achieve power control. We would be happy to have you and your organization as part of our valued clientele.

A10VSO 18 DFR Pump

Agreed, the pump pkmp description refers to a pressure and flow controlled pump but the flow control has to be achieved by means of an external throttle valve not part of the pump control which would be a standard arrangement for a load sensing pump. Number of Employees 11 to 25 People.

A10VSO Variable displacement pump power control So you are saying that both compensators a1vso are on the drawing and visible in the pictures are actually a10vsl working? I am glad to help I am glad that the help has been worthwhile. Yes, it’s not a load sensing system as such, but the principle of controlling the flow is to use the proportional valve to change the pressure drop over the orifice. I agree to the terms and privacy policy. A10VSO Variable displacement pump power control I have had a closer look and the following is what “should” be happening.
