The hydraulic speed governor is a closed-circuit system, coupled – as a rule – with a pneumatic cylinder.
This device is used to adjust and standardise the speed of a linear actuator, and can be installed also on systems other than cylinders.
Characteristics
This system exploits oil incompressibility:
flowing through a flow regulator, it absorbs and neutralizes any speed variation in the connected system, which can be either a pneumatic cylinder or another device.
Hydraulic speed governors can split, by means of suitable procedures, the different processing stages, and make it possible to approach the pieces more quickly, to speed-up or slow-down the processing steps, to accelerate the approach to the next piece, to complete other slow working stages etc.
