Self-contained linear drive with fail-safe function
3rd Quarter 2013
Electrical switching & drive systems & components
The newly developed electrohydraulic linear drive from Voith regulates control valves on turbines precisely and in a highly dynamic way. It is self-contained, meaning it operates without a hydraulic power pack. In addition it has an integrated spring assembly so that the drive can close the control valve in less than 200 ms in the event of a malfunction. This fail-safe function increases the operational reliability of the system and avoids the costs of secondary damage. This drive is a plug and play solution that is optimally suited for both new systems and the modernisation of existing equipment.
The hydraulic system is self-contained. Oil management is not required because there is no ingress of dirt from an external source. This saves the cost of operating material, pipework, wear parts and maintenance work. Operation of the linear drive is maintenance-free and it also offers all the benefits of a hydraulic solution, for example high power density and reliability. The position is controlled using the suppression principle via a servo motor and a servo pump.
This type of position control is highly energy efficient, while the level of heat introduced to the system remains low. This reduces energy costs by up to 50%. Lower CO2 emissions contribute to climate protection. The modular design of the linear drive enables very flexible integration into the turbine control system. Installation in new systems or during a retrofit is simple, quick and cost-effective.
