  • Positron as a new tool for research on lithium-ion batteries

    TUM0117 Research Report

    Batteries, the cathode consists of a mixture of nickel, manganese, cobalt and lithium, are currently considered the most efficient. But they have a limited lifespan. From the first cycle they lose up to 10% of their capacity. Why is that and what can be done against the subsequent gradual loss of capacity,... Continue reading

  • Stuttgart researchers produce extremely powerful lens system

    nanoscribe0117 Research Report

    Adler eyes are extremely sharp and can see both forward and sideways good - qualities that one would like to have also the autonomous driving. Physicists at the University of Stuttgart have now produced in 3D pressure sensors that track the eagle eye in a small space and with the latest 3D printing technology realized by Nanoscribe.

hoven1211The construction of tunnels is one of the most demanding challenges in civil engineering. For used tunnel boring machines that must work in the tunneling process through very hard rock, has Hoven Hydraulik customized hydraulic components. The Stolberg develop and manufacture on behalf of customers including application-specific feed cylinder with particularly high power density and compact dimensions.

With tremendous force these hydraulic cylinders provide below ground for the necessary contact pressure of the drilling head. Variety of soil conditions, strong vibrations and permanent stains impose extreme demands. For maximum performance, the cylinder of resilient materials, manufactured with minimal tolerances and engineered sealing and bearing solutions.

A current project is the construction of 3000 m long pressure tunnel in Reisseck II pumped storage power station in Austria. There you initially wanted the old feed the cylinder boring machine repaired again translated. The higher performance was desired, however - due to heavy wear - not realizing by Recylindering. So developed and manufactured the hydraulic cylinder specialists new feed - tailored for the demanding task and the limited space inside the tunnel.

In the machine with a bore diameter of 7,03 m now afford four newly manufactured cylinders feeding force totaling 12.750 kN. The maximum piston rod stroke is 1,75 m. Each cylinder weighs more than 3 t. The nickel-chromium coating on the piston rod and a proven sealing concept protected from mechanical damage.
