Air and oil do mix

The wind power and petroleum industries may be seen as rivals, yet oil is essential throughout a wind farm to ensure smooth operation. As such, it is necessary to select the right accumulators for both hydraulic and lubrication applications.

Wind turbine manufacturers typically speak of having availability levels in the range of 97% to 98%, but a 2008 study by British wind consultants Garrad Hassan found actual availability levels to be lower. In North America, turbines were averaging an availability of 94% to 95%.

    Accumulators help keep heads on straight 2

    Hiram Moore invented the combine harvester in the U.S. in 1834. The machine  combined three separate operations — reaping, threshing, and winnowing — into a single process. But it wasn’t until 1911 that the self-propelled harvester was introduced. Eventually, hydraulics were incorporated to make the machine more versatile and productive. Today’s combines are equipped with removable headers for use with particular crops— wheat, oats, rye, barley, soybeans, etc....More
