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.
The Deriner Dam is one of Europe’s largest, and thanks to hydraulics from Rexroth it is also one of the safest.
Bosch Rexroth replaced the main gate hydraulic drive machinery through its Hägglunds motor drives offering.
The EFC 3600 series variable-frequency drives from Bosch Rexroth are suitable for applications including general automation, materials handling, pumps, fans and conveyors.
As a major engineering partner to the Allseas Group, Bosch Rexroth has developed a drive and control system for the world’s largest mobile lifting mechanism for offshore installations.
Machine builders are increasingly under pressure to build energy-saving features into their industrial machines. Andrew Davies, an expert in machine building at Bosch Rexroth, argues that capacitance modules could offer a simple solution.
