The variable angle swash plate was
invented as a simple and reliable
way to transform rotational power
into motion and has been the main
mechanism used to create variable
flow output for almost 120 years.
Efforts have been made to digitise the
mechanism with feedback and electric
control systems and it has served
our industries well but it’s time for
hydraulics to move out of the analogue
age and engage with the benefits of
true digital control. a radial piston mechanism and an
embedded controller that enables
individual cylinders in real time by
actuating ultra-fast mechatronic
valves.
A fundamental innovation The control of individual cylinders
also allows a single pump to have
multiple independently controllable
outlets providing industry innovators
Invented by Artemis Intelligent Power,
the Digital Displacement Pump uses
The fast acting valves and controller
allow for high bandwidth control
of pump output. The ability to use
only the cylinders required to meet
the load results in a pump with an
efficiency of greater than 90% over
most of the operating range.
a platform to invent new architectures
to capitalise on the capabilities of
digital pumps.
With inherent digital control, set
points and operating parameters can
be remotely monitored and controlled
to optimise performance. The pump
is able to create real time data about
the state of the hydraulic system.
Already a number of industries are
adopting this new approach and
utilising digital hydraulics to explore
the savings and new features Digital
Displacement can bring.
In industry, it is ideally suited to
applications with wide pressure and
flow requirements including injection
moulding, water jet cutting and
hydraulic power units.
The industries of tomorrow will
continue to evolve and Digital
Displacement technology will be
a core component of the smart
machines of Industry 4.0 and beyond.
