Hydraulic system energy savings
May 1st 2009 Installing an ABB industrial drive is
reported to have resulted in a 70%
energy saving on a hydraulic system
for steel manufacturer, Corus Colors
at Deeside. The hydraulic system used
during the trial is located on a
production line used for retreating
and inspecting strip material, driving
actuators and web guiding systems.
As a result of the variable speed
drive being retro-fitted, pump speed
was greatly reduced both when the
system was in neutral and during
actuation of the cylinders.When in
neutral, power consumption was
initially around 9kW. Under drive
control, power consumption was
reduced to 2kW, a reduction of 77%.
With the system under load, power
consumption was reduced from 22 to
12kW, a saving of 48%. More articles from ABB Ltd: |
