Deriner Dam hydroelectric power plant uses hydraulic drives supplied by Bosch Rexroth
Bosch Rexrothcontact supplier
Hydraulics from Rexroth have been utilised in the construction of the Deriner Dam on the Coruh River in north-eastern Turkey. The drives have been used in an underground hydroelectric power plant comprising four turbines that will generate 2,100GWh.
Two large tilting gates, which feature Rexroth drives, provide flood discharge capability. The gates divert surplus water into the basin at the foot of the dam via two artificial diversion tunnels. Eight central outlet gates have been integrated into the main damn structure to cope with ‘flood of the century’ conditions.
As a project partner of ERG Trade and Industry, Bosch Rexroth was responsible for the drive and control system for the central outlet gates and the two tilting gates. The local branch office supported the conceptualisation, assembly and installation.
The opening drives for the central outlet gates represented a big challenge for the design of the hydraulic drives, as each gate measures 2.8 x 5.6m and weighs 24 tonnes. Despite this weight, the corresponding drives must work in parallel with a high degree of precision to ensure the gates always open and close in sync.
The answer was to mount the drive cylinders of the central outlet gates vertically in the drives.
Key benefits of product application
- ERG Trade and Industry benefited from having just one partner for all flood discharge issues.
- The drive cylinders are made of lightweight special steel.
With oil becoming harder to exploit and prices increasing, operations are moving into deeper waters. Active-heave users need to move towards more energy-efficient solutions as subsea activity needs more power to deploy the equipment to reach these hidden depths. Steve Smith, marine and offshore sector manager at Bosch Rexroth, says by innovative system design and integrating accumulators into the active-heave compensation control process, end users could achieve energy savings of up ...
Bosch Rexroth introduces Nexo nutrunner for bolt tightening in safety-critical applications download
Bosch Rexroth has launched the Nexo nutrunner: a cordless tightening tool specifically designed for bolt tightening in ‘Category A’ safety-critical applications.
Bosch Rexroth has announced that developments in its Linear Motion Designer 2.1 will make it easier to quickly and effectively design tailored assembly and production lines. One of the key developments in the free-to-use program is that it is now much easier to design profiled rail systems and screw drives independently. Likewise, process data only needs to be entered once, with users able to configure a range of variants to design a solution that is optimised for the specific application.
Bosch Rexroth’s IndraControl XM21/22 programmable logic controller (PLC) combines the speed of the Sercos automation bus with Rexroth’s IndraControl S20 input/output (I/O) series for one functionally complete and scalable control system.
Software and technology such as intelligent servo drives from Bosch Rexroth have enabled Focus Label Machinery, a manufacturer of printing presses, to incorporate further automation into its latest flexographic printing press.
