Discussion Overview

The discussion revolves around the design and functionality of a hydro pneumatic circuit utilizing a pressure booster or intensifier to achieve hydraulic pressure. Participants explore the implications of blocking the oil path in relation to pressure increase and the mechanics of pressure boosters.

Discussion Character

  • Technical explanation
  • Exploratory

Main Points Raised

  • One participant inquires about the effect of blocking the oil path on pressure increase when using a pressure booster.
  • Another participant suggests that the outcome depends on the type of intensifier being used and requests more information about the specific device.
  • A third participant reiterates the need for details about the intensifier and proposes an alternative method using a hydraulic cylinder with oil on the rod side and air on the piston face.
  • A later reply asserts that blocking the oil path will indeed lead to an increase in pressure, explaining that the pressure ratio is determined by the area ratio of the cylinder to the rod, and notes limitations on the volume of oil available per cycle.

Areas of Agreement / Disagreement

Participants express varying views on the mechanics of pressure boosters, with some uncertainty regarding the specific effects of blocking the oil path. There is no consensus on the best approach or the implications of the design choices discussed.

Contextual Notes

The discussion includes assumptions about the type of pressure booster and its operational characteristics, which may affect the outcomes discussed. The relationship between input pressure, compression ratio, and output pressure is noted but not fully resolved.

Hello,
I am trying to design a hydro penumatic circuit. I have shop air at 80 Psi. I need hydraulic pressure of 160 PSI. So I am using pressure booster/Intensifier to pressurise it. there will be air on one side of intensifier and oil on other side of it. my question is if I block path of oil will there be increase in pressure?

Welcome to PF.

It will depend on what type of intensifier are you using.
Please give us a link to the device.

If all you want is pressure with very low flow you might be able to use a hydraulic cylinder with oil on the rod side and air on the piston face. Many cylinders have a rod area that is close to half the piston face area.

Thanks for your reply.

Yes. The pressure ratio of a booster is fixed by the ratio of cylinder area to rod area. The maximum output pressure will be the input pressure * compression ratio.
The volume of pressure boosted oil available per cycle is limited to the booster cylinder oil capacity.
If you do not block the oil path, the booster will push oil through the system until the booster reaches the end of it's travel, without reaching the full boosted pressure.
