Hydraulic Pressure Intensifiers: How Can They Help Improve Your System Design?

Blog | October 16th, 2018

Hydraulic pressure intensifiers are built to deliver great quantities of pressure through a smaller than average package. Proven to take lower input energies and convert those fluid energies to higher output pressures, the device doesn’t need to break any laws of fluid thermodynamics when it performs this impressive feat. In reality, an intensifier (also known as a booster) comes equipped with a gifted hydraulic architecture.

The Less Energy In, More Energy Out Magic 

Like many electronic components, a hydraulic pressure intensifier has access to a secondary power source. Like a gated transistor, the low inlet pressure is boosted by a supplementary power source, a signal or energy boosting energy line that improves system design. Instead of an independent electrical signal, the pressure intensifying component uses a pump, a component that generates the added output pressure. Architecturally, this piston-based design uses a large diameter mechanical plunger to drive a piston plunger that employs a smaller diameter.

Simplifying System Designs 

A low system inlet pressure is flowing. The powered pump is active, and the differential piston design is performing its duties, as directed by a powered pump. This configuration sounds more intricate, not simple at all. In truth, however, hydraulic pressure intensifiers are packed inside self-contained cylinders, which can be installed on new or existing mobile excavators. The circuit layout of that compact cylinder suggests in-line usage, so the installation skills required here are minimal. Furthermore, that aspect of the design has been intelligently augmented, so expect standard pipe clamps and fittings when undertaking the installation phase.

Versatile Fluid Force Enhancers 

If the in-line models don’t suit a particular circuit-enhancing application, these pressure boosting parts can also be sourced in other common forms, including flange-on variants and CETOP (European fluid transmission committee) compatible models. Again, the goal is to reduce system complexity, to compartmentalize and create a self-contained pressure augmentation architecture. As such, intensifiers are commonly found installed on mini diggers, excavators that have little room for complex valves and fluid actuation assemblies. Functioning alongside a Hydraulic Power Unit (HPU) or a capable fluid power pack, this smart component ensures low-pressure generation throughout the hydraulic network, but it also ensures a high-pressure throughput is available right where it’s needed.

Siding with today’s contemporary modular circuit elements, hydraulic pressure intensifiers boost circuit pressure, but that boost only occurs at the point in the system it’s required, not all throughout the system. As a result of this design advantage, the input pressure stays low, the system enjoys less stress, and there are major savings to be gained. Installed as a single force-amplifying package, these force boosters do improve a hydraulic system’s design, plus there’s that performance upgrade to appreciate.
