HYDRAULIC SPEED GOVERNORS
Open the catalog to page 1
Requirements 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...

Cylinder adapter plate (ISO) N M Maintenance The hydraulic speed governor is a closed circuit system, and therefore no factors can negatively affect its operation. Be careful with the hydraulic oil level, for it must never drop below the minimum level indicated by the drip stick of the auxiliary tank. Otherwise, cavitation or air bubbles inside the circuit would hinder system regulation. Top-up the oil, if necessary, only through the dedicated unidirectional valve mounted on the rear head, by means of an oil syringe. Excess oil will be ejected through a small drain hole on the tank....
