Key Selection Parameters for Hydraulic Pressure Intensifiers/Boosters

In the realm of engineering hydraulics, there are instances where your typical pump isn't equipped with the "teeth" to perform the task. If you're powering a high-pressure bolt tensioner, a hydraulic cutter, or a press for a laboratory, using it is a Hydraulic Pressure Intensifier (or Booster) is often the most efficient option.

The right choice. It's not only about selecting the most efficient ratio. It is about balancing pressure, flow, and compatibility of the system. Here's a list of the most important factors to consider when choosing a system.

1. Ratio of Intensification

The most essential element is the ratio of pressure at the source (low) and output (high) tension. This is measured via the surface ratios of internal pistons.

The formula is typically formulated as follows:

The Plow is the Plow multiplied by Intensity Ratio

  • Common Ratios. It is common to discover boosters ranging between 1.5:1 and 20:1.

  • The trade-off: High ratios give the user immense pressure, but reduce the flow rate at which you get. Make sure your pump is able to supply enough pressure for the input to achieve your output goal.

2. Cycle Speed and Flow Rate

An error that is common is focusing exclusively on pressure and ignoring the importance of displacement.

  • Inlet flow ( Qin): The amount of fluid that the booster requires for operation.

  • Outlet flow Qout): Because of the intensification ratio that flow output is smaller than the flow that enters it.

  • Dynamic and static: If you need to keep pressure on a cylinder that is static (like clamps), it is less crucial. If you're using the movement of a tool and you want to know whether the booster is able to run at a speed that is sufficient in order to satisfy your cycle speed needs.

3. Media Compatibility

What liquid are you pumping? There aren't all intensifiers designed to work with all liquids.

  • Oil-to-Oil is the most commonly utilized in standard industrial machines that are standard.

  • Water-to-Oil: It is used in hydro-testing and water-jet applications. They require special seals and stainless steel parts to stop corrosion.

  • Dual Media Certain intensifiers permit a hydraulic oil "drive" side to be powered by a completely separate "high-pressure" part of the fluid, which prevents cross-contamination.

4. The Mounting and Control Style

How the booster fits into your existing manifold circuit can affect both the cost and performance.

Mounting Type The Best for...
In-line Simple systems in which the booster is connected to an existing line of hose.
Flange/Manifold Integrated OEM machinery when the space is constrained, and leak points have to be reduced.
Reciprocating Applications that require continuous flow. These boosters are able to automatically move back and forward.

5. Accuracy at the end of the pressurization and safety

In high-pressure areas, which can often exceed 10,000 PSI (700 bar)--safety and precision are crucial.

  • Valve Integrated for Relief: Make sure the booster can let out pressure when the system fails to head or is over the limits.

  • Hysteresis Search for units that have low friction inside to ensure that the pressure shown on the gauge is actually the pressure that is placed on your work.
