A10VSO 18 DFR Pump
Thank you for helping keep Eng-Tips Forums free from inappropriate pumo. It’s easy to join and it’s free. Correct me if I am wrong here Adrian. If it’s just a close and push like a coining press the power limit control is not really required. However, such an orifice is always in the line of the output flow from the pump.
You can use a Fluke or similar to measure actual consumed power. Yes one could view it as the regulator is trying to keep a constant deltaP across that 1mm orifice it does for sure but that view is not helpful in this application since the orifice sits in a T’ed of branch of the main flow. The pump delivers maximum flow until the pressure increases to a level where the power limit is reached.
The spring of the controller now again tries to increase the flow but the resultant pressure drop again reduces the flow. So what is the point of the 1mm orifice, if it is a10fso there to provide a pressure differential for the flow control. I found a document of Parker, explaining the same load sense control in each stage. If cookie is disabled you’ll see the site in the original language. Pressure is a direct result of resistance to flow, so the control of pressure and flow x10vso similar, not the same, just similar.

However, it’s all relative to what the press is doing. The orifice also creates a pressure differential to enable the pump to de-stroke when the pressure differential reaches the setting of the bias spring.

You’ll agree once you understand how a load sensing pump works”. HPost 7 Jan 16 That pump controller would be perfect for this application and it has one spool less. From the consumer, the hydraulic fluid flows directly back to the reservoir. Your health is a10vo more important than how this stuff works. Defense manufacturing is all about project manufacturing and project accounting.
If we can confirm the diameter of the orifice, we can calculate the pressure drop when the pump is at full stroke, then start to look at what flow area would be needed through the proportional valve. As drawn the system gives Power, Pressure and Flow Control.
This is a standard method of achieving remote or proportional pressure limiting when the pump doesn’t have a two-stage compensator. The power limiting is achieved with the pilot relief valve closest to the pump. 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.

Get best deals for coconut. Usually but not always an increase in pressure will increase the flow. I am glad to help I am glad that the help has been worthwhile.
However, the pictures do not tell the same story.
