HUSUM WindEnergy 2010: Efficient Maintenance of Wind Turbines
Innovative products for an optimized utilization of bearings' service lives -
Herzogenrath/Husum, September 16, 2010 - At this year's HUSUM WindEnergy trade fair from 21 - 25 September 2010, FAG Industrial Services (F'IS) which takes responsibility for Schaeffler Industrial Aftermarket's service business, will showcase a broad portfolio of innovative maintenance products and services for the wind energy industry at the Schaeffler Group Industrial booth (Hall 2, Booth 2B05). The F'IS experts will present, among others, solutions for the optimized lubrication of wind turbines as well as the new FAG Wear Debris Monitor oil sensor and the compact online monitoring system FAG WiPro s.
One big challenge to the operators of wind turbines is to ensure that the bearings are permanently supplied with lubricant. The lubricant film between the bearing components is constantly replenished by regularly supplying small quantities of lubricant. That reduces friction and the contamination of dirt particles. Automated central lubrication systems considerably simplify relubrication and help optimize the bearings' operational reliability and wear behaviour. The Schaeffler Group offers a range of relubrication solutions for wind turbines that are always tailored to a customer's specific requirements, using products from the Schaeffler delivery programme or outsourcing components from renowned manufacturers. Apart from the right amounts of lubricant, selecting the right type and quality of lubricant contributes to ensuring that bearings reach their specified service lives. That is why the Schaeffler Group offers a wide range of high-performance lubricants under the brand name Arcanol. These include, among others, two special greases for wind turbines - Arcanol LOAD400 and Arcanol LOAD460.
Another highlight at the booth will be the new oil sensor, FAG Wear Debris Monitor. In combination with FAG vibration monitoring solutions, the sensor makes it possible to detect damage to oil circulation lubricated gearsboxes - like planetary gears in wind turbines - at a very early stage. The underlying principle is very simple: wear in bearings or gear wheels becomes visible months before their actual failure in the form of rubbed-off metal particles in the oil. The FAG Wear Debris Monitor constantly screens the oil for such wear particles, permitting detection of damage at an early stage. The FAG Wear Debris Monitor can be integrated with little effort both into new FAG online monitoring systems like the FAG WiPro s and into existing systems already installed at a customer's. The combination of oil particle monitoring and vibration monitoring permits a very early detection and identification of damage as well as a precise location of the area of origin within the gearbox.
The new FAG WiPro s is an online monitoring system that was developed especially for the requirements of the wind energy industry. It monitors not only the complete power train (main bearings, gearbox, coupling, generator) but also the tower's vibrations. Optionally, the system can monitor additional parameters - from the rotor blades' vibration to the condition of the lubricating oil. In this way, the FAG WiPro s, which is based on the successful FAG WiPro, permits reliable and cost-efficient monitoring of wind turbines. Unlike its predecessor model, the system unites all modules in a single housing and is thus significantly smaller. The FAG WiPro s is currently being certified by Allianz Zentrum für Technik (AZT). This certification creates the prerequisite for reducing the insurance terms and conditions for wind turbines.
The Schaeffler Group not only offers a wide product portfolio but also supports customers with a broad range of services. For example, the e-service capability of all online monitoring systems permits external monitoring of offshore wind turbines by the Schaeffler Group. Additional services include the mounting of bearings. At HUSUM WindEnergy, induction heating by means of medium frequency technology will be showcased, a special service for mounting large rolling bearings and other circular components in a simple and cost-efficient manner. Medium frequency induction heating is particularly suitable for the wind energy industry as this method can be used to both mount and dismount large bearings.
The Schaeffler Group's many years of experience and broad range of services enables it to offer every customer a service package that is tailored to their individual requirements.
Schaeffler Group Industrial The Industrial Division of the Schaeffler Group supplies rolling bearing and plain bearing solutions, and linear and direct drive technology under the INA and FAG brands for around 60 different industrial sectors via its worldwide organization with market proximity and application support service. The range comprises more than 225,000 products from miniature bearings only a few millimeters wide, e.g. for dental drills, to large bearings with an outside diameter of many meters, e.g. for wind turbines. The Schaeffler Group and its 61,000 employees at more than 180 locations worldwide generates group sales of 7.3 billion euros (FY 2009) and ranks amongst the leading rolling bearing manufacturers and suppliers to the automotive industry worldwide.
