Hydraulic actuator of turn-over cooling bed section skid for continuous -casting machines

Hydraulic actuator includes electronic control system that consists of an electronic timing unit with a microcontroller, and each hydraulic cylinder is equipped with a displacement sensor, connected to the corresponding output channel of synchronization electronic unit, while to output channels of the latter through the analog amplifiers connected are electromagnets of two-way proportional charge regulators, at that, the microcontroller is adapted to provide synchronization of operation of lift cylinders with move cylinders in accordance with a predetermined operating cycle of the hydraulic cylinder.

Cylinder supply with electronic control system allows to improve the synchronization of its cylinders as well as significantly increase the reliability of hydraulic cylinders in general.
