FIELD: power industry.
SUBSTANCE: nodes of variable length can be implemented in various ways (screw connection with integrated hydraulic drive). The proposed variable-length connections have the following advantages: they enable minimisation of the relative movements of rotors relative to cylinder bodies; allow to speed up starts and stops of turbines due to control of relative movements; provide minimum movement of rotor on the generator.
EFFECT: minimisation of thermal movements of rotors relative to the cylinder bodies due to changes in the length of connection between the cylinder bodies and bearings.
