HYDRAULIC SPEED GOVERNORS

Product catalog summary
Requirements
The hydraulic speed governor is a closed-circuit system typically paired with a pneumatic cylinder. It is designed to adjust and standardize the speed of a linear actuator and can be used with systems other than cylinders.

Characteristics
This system utilizes the incompressibility of oil to absorb and neutralize speed variations in connected systems, such as pneumatic cylinders. It allows for the segmentation of processing stages, enabling faster approaches to pieces, acceleration or deceleration of processing steps, and completion of slow working stages.

Operating Principle
The governor operates on the principle of oil incompressibility, flowing through a flow regulator to manage speed variations in a linear actuator. It can split processing stages and is equipped with skip and stop valves, which are 2-way pneumatic glove valves. These valves require pneumatic pressure to operate, with the skip valve featuring an auxiliary maximum speed governor. The system includes an auxiliary tank to manage volume differences and leaks, with a spring-pressed piston ensuring slight overpressure and a dip stick indicating minimum oil levels.

General Characteristics
  • Heads: Aluminium
  • Liner: Drawn steel
  • Tie rods: Galvanised steel
  • Stem: Chromium-plated steel C43
  • Piston: Aluminium
  • Piston gasket: NBR or Viton
  • Stem gasket: Polyurethane
  • Adjusting units: Stainless steel
  • Skip and stop valves: Aluminium
  • Circuit oil: Hydraulic oil, viscosity: 2.9E – 50°C
  • Max. load: 600 kg
  • Speed range: 60 – 10000 mm/min
  • Working temperature: -10°C to +70°C
  • Min. actuating pressure for valves: 4 bar

Maintenance
The system is closed-circuit, minimizing operational interference. It is crucial to maintain the hydraulic oil level above the minimum indicated by the auxiliary tank's dip stick to prevent cavitation or air bubbles. Oil should be topped up through a dedicated valve using an oil syringe, with excess oil expelled through a drain hole.

Additional Information
The document includes a coding key for different configurations and a table with specifications for cylinder adapter plates, detailing dimensions and codes for various models.

HYDRAULIC SPEED GOVERNORS-2

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 possible...

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.
