HAWE Hydraulics, a global manufacturer and supplier of sophisticated hydraulic components and controls for the mobile, industrial, and renewable energy markets has added the V40M to its line axial piston pumps. The new pump has been designed for open-circuits in mobile machines and has a displacement volume of 2.75 in3/rev. Its swash plate design makes it
How are hydraulics used in wind turbines?
April 25, 2013 : 0 Comments
The wind-energy industry makes good use of hydraulics, in particular how well it combines power density and durability for the muscle needed to pitch turbine blades that easily weigh two to three tons. In recent years, however, most utility-scale wind turbines for land installations have turned to electromechanical systems for this function. Electromechanical systems typically

Parker Hannifin has introduced the compact, icountBSplus, a fully contained, portable bottle sampling system that uses laser particle counting technology to ensure the fast and accurate detection of contamination in hydraulic oils and hydrocarbon fuels. A key component of the fluid-particle analysis and monitoring portfolio, the icountBSplus helps improve the reliability, productivity, and profitability of
What you should know about gearbox filters and breathers
February 20, 2013 : 0 Comments
Filters and breathers on wind-turbine gearboxes must work under conditions found in no other industrial setting. Gearbox oil, for instance, undergoes large viscosity changes due to a wide temperature span and operating conditions. And then there is potential for a high water content in the oil from humidity and condensation. “Most current maintenance practices are

OEM begins test on what could be 7 MW hydraulic drive train
January 25, 2013 : 1 Comment
In December, Mitsubishi Heavy Industries, Ltd. (MHI) commenced test operation at its Yokohama Dockyard & Machinery Works of a large scale, hydraulic drive train in place of a conventional gear-driven system. The test operation is a part of the project launched in September last year to develop a hydraulic drive train for offshore wind turbines.
Goodbye gearbox, hello hydraulics
October 4, 2012 : 4 Comments
The U.S. wind energy market includes roughly 30,000+ aging turbines. Of those, around 7,000 are down for repair at any given time. The bulk of repairs are gear failures in gearboxes and yaw drives. Other turbine-stoppers include main-shaft bearings and seal failures, electrical generator overloads, and over-speed brake failures. High costs and duration of repairs
