Hydraulic unit for actuator control

The Hydraulic Power Unit is at the service of a single-acting hydraulic actuator that operates a rotary valve located in the main steam overflow line.
The task of this valve is to regulate the pressure in the steam supply line of the turbine by discharging geothermal steam.
This valve, controlled by the Hydraulic Power Unit, must therefore have an adjustment, shut-off and emergency (fail safe) function.

Control unit with IO-Link type instruments

The control unit performs the most classic of applications, namely the hydraulic control for locking and unlocking the equipment of a machining center.
But in this case the difference, or rather the innovation, is given by the type of instrumentation and the connection method between the control unit and the electrical control panel of the machine.
The customer asked us that all the instruments (level sensor, temperature sensor, pressure transmitters and filter clogging indicator) were of the IO-Link type and that the classic junction terminal block was replaced by the IO-Link interface modules. Profinet.
In this way, the signals of the solenoid valves were also connected to the same modules, with the result of a simplified wiring procedure, the use of a much lower number of cables, in addition to all the advantages deriving from the use of components with IO-Link (ease of configuration, possibility of implementation in an Industry 4.0 system, etc…).

Solution for docking ships with a suction cup

The solution designed by Hydroservice controla a movable arm, so that the suction cups are put in contact with the wall of the ship: the vacuum pump with which the machine is equipped sucks the air contained in the suction cup, effectively causing the ship to hook to the suction cups.

Furthermore, with this method the docking time is reduced up to 10 times.
