Hey,

I have some questions on these.

If I had a hydraulic power pack which was running at 200 bars and 100 litres per minute, could I install one of these and have the system running at 600 bars and 100 litres per minute?
Is it really possible to install one of these babies and get extra pressure without the system requiring more electricity?

Thanks in advance!

No.

Yes.

Intensifiers always require higher Flow Volume to ahieve higher pressure or another way to say it is: they sacrifice Output Flow Volume to gain higher pressure. In your scenario the Output Flow would be 33 1/3 LPM at 600 Bar

Take a look at my EBook Chapter 17 on Air-Oil and Intensifier operation here:

Air and Oil Intensifiers are in the second half of the chapter.

OK. Thanks for the response. I have one final question.

Do these intensifiers slow down the piston's movements?

Thanks in advance.

This quotation from my previoy=us post indicates out put flow at the elevated pressure of 3 times input pressure would be 1/3 of the intensifier input flow.

It seems obvious that will reduce the actuator speed to 1/3 as fast as it went before intensified pressure was required and produced.

I grew up with an old saying that indicated "You can't get something for nothing" Higher pressure is gained by the reduced flow. A large Piston driving a smaller Piston of 1/3 the area automatically reduces flow at the intensified outlet. You could maintain the original lower pressure outlet by making inlet flow 3 times faster though.

Did you read the chapter on Air-oil circuits in the book I referenced in th last post?

Do you actually need full flow at elevated pressure throughout the entire stroke? Can you stroke the cylinder using pump flow at low pressure, then engage a seperate high pressure circuit?
