A10VSO Variable displacement pump power control I have had a closer look and the following is what “should” be happening. Just remember, the control strategy of the pump is to maintain the pressure drop across the orifice.

Nature of Business Manufacturer. I wouldn’t normally be so insistent, but they way I have explained it really is the way it works. And so I strongly would be interested to understand how you make the other side of the Atlantic Ocean to use puml without power control.

A10V(S)O variable piston pump – Rexroth

The delta pressure at the compensator will be pkmp same as the pressure drop across the orifice. It could be also be as simple as Rexroth stocking the A10 with DRS regulator and that there was a long a10vsk time for something more suitable or maybe it was cheaper.

A10VSO Variable displacement pump power control So what is the point of the 1mm orifice, if it is not there to provide a pressure differential for the flow control.

The pump part number and controller matches what is shown on pukp drawing. Following are the design and performance advantages of this product. It is usually around – kPa. Join your peers on the Internet’s largest technical engineering professional community. Could you give us the signal values proportional pressure relief valve according to the desired flow rate at the pump?

It is common to use a small relief valve in combination with an orifice to pilot control another valve very common on larger logic element type of valves. Proportional to the drive speed and displacement, the flow can be smoothly adjusted by regulating the swash plate position. Sure it phmp as a backup like Bumblyari says but that may not be the only reason that it is there. A small orifice is needed upstreams to limit the flow to the small prop relief valve.

The A10VSO range a10vwo variable displacement piston pump is designed for use in open circuit hydraulic system, and comes with swash plate design.

So you are saying that both compensators that are on the drawing and visible in the pictures are actually not working? The spool modulates to maintain the flow at a required level, say 65 lpm. The proportional relief valve enables the cut off pressure to be set electronically. There is no load sense line coming from the press cylinder and when EV3 pumo energised there is nothing between the pump and the press cylinder other than a straight-through piece of pipe, so no flow control.

We would be happy to have you and your organization as part of our valued clientele. Your health is much more important than how this stuff works. Why have lump pressure cut off compensator on the pump and a relief valve on the press as well then?


The valve will have its own orifice to dampen its action. The A10VSO is designed for stationary applications such as tooling machines. This is how flow control takes place in a DRS control.

I found a document of Parker, explaining the same load sense control in each stage.

Piston Pumps in Mumbai. Actually, I’m in England. The operation noise is very low.

By changing the setting on the proportional relief valve, the pressure drop across the orifice will change and so the pump will change its flow to compensate. When the prop press valve is closed the LS port is connected straight to P and will cause the pump to swivel up as much as it can.

On the machines I am responsible for, we use the main spool as the variable restriction and we have similar pump that responds to the changing pressure differential.

Variable Displacement Pump A10VSO / A10VO

Why is there an LS-spool to start with, why not just a pressure compensator spool? Table of Values Size A Shop Cookie, which saves data about orders, carts, IP of the clients.

This keeps on happening the flow gets reduced until the pressure drop is equal to the spring setting of the DRS control.
