An exciting future for the hydraulics industry
Many people have a tendency to view hydraulic systems as
‘old technology.’ This is not surprising when you consider their history. The
Ancient Greeks were skilled at hydraulics and constructed water-powered wheels,
simple hydraulic pumps and sophisticated irrigation systems as long ago as 300
years BC.
However, one of the striking things about the hydraulics
industry is that it keeps finding exciting new applications for this
technology. Wind Turbines are a relatively new technology, but hydraulic
systems play a vital role in their construction and operation. Despite the
high-tech nature of many modern oil and gas installations, hydraulic systems
still form the backbone of many of these facilities. Some of the latest and
most sophisticated solar farms require the use of hydraulics to rotate the
solar panels so that they track the movement of the sun. And of course, the marine
application of hydraulic systems is becoming ever more complex, from
superyachts and commercial ships to advanced military vessels.
One of the key strengths of hydraulic systems is their ability
to generate a high level of power density. That is one of the main reasons why
hydraulic systems haven’t been supplanted by electrical drive systems, apart
from in certain specialised applications. And industrial clients continue to
demand more and more power density. Added to this, modern hydraulic systems can
be built to be very reliable and robust.
Hydraulic technology has not stood still. There have been a
number of important improvements over recent years, including more advanced and
‘smarter’ pumps, valves and actuators. One example of this has been the much
wider use of variable displacement pumps, which help to deliver greater energy
efficiency.
The industry continues to innovate, and I think we can
expect the following changes over the next ten years:
Smarter hydraulic
systems. There will be a continued evolution of sophisticated electronic
control systems, allowing for better, more precise operation.
User-friendly operation.
There will be more focus on systems that require less specialist training in
order to be operated. Making systems more user-friendly in this way will
increase their value and usefulness for the owner, while also helping to reduce
the risk of damage through operator error.
More advanced
components. We can expect to see significant improvements in quality and
performance for many different components, including control valves, hoses and
hydraulic fluids.
Reduced environmental
impact. Operators will become more demanding in wanting lower emissions,
reduced carbon footprints and systems which protect more effectively against
leaks and environmental contamination.
Increased energy
efficiency. This will be needed in order to improve the commercial payback
from hydraulic systems and cut down on any unnecessary waste of energy. At the
same time, operators will be looking for systems that have reduced noise and
vibration, while also delivering improvements in reliability.
Intelligent
maintenance. The use of high performance sensors will allow big leaps
forward in pro-active maintenance. Systems will be continuously monitored so
that maintenance can be performed on the run, rather than waiting for scheduled
downtime. This will extend the overall life of equipment and reduce the cost
impact of unexpected repairs.
You can see from all the above trends that the hydraulics
industry continues to change and adapt in order to deal with new technical
challenges. Far from declining in importance, hydraulics continues to find
diverse and specialised applications across a range of industries. In fact, the
next decade could be one of the most exciting and important periods of growth
and development for the hydraulics industry.
Not bad for a technology whose roots can be traced back more
than 2,000 years.
