determination of characteristic curves and setting curves of different centrifugal governors
| Code | TM632 |
Description:
- Centrifugal governors use the properties of centrifugal force to control the speed of a machine.
- Due to centrifugal force, a rotating flyweight mass has the tendency to move away from the axis of rotation and is prevented by counteracting mechanisms.
- These mechanisms are differentiated into those governors that use weights and those that use springs.
- Corresponding kinematics cause a deflection proportional to the speed to occur on the governor.
- Via an actuator, this affects the energy supplied to the machine, thereby controlling the machine’s speed.
- The TM 632experimental unit presents centrifugal systems that demonstrate the different principles of operation of both weight and spring-based governors.
- The housing holds the drive with an electronically controlled motor.
- The speed is continuously adjustable and displayed digitally.
- The governors are inserted into a chuck on the drive.
- Centrifugal masses, sleeve forces and spring preload can be varied using the accessories supplied, depending on the governor.
- The stroke can be read on markings on the governor shaft.
- A transparent protective cover above the rotating centrifugal governor ensures safety: operation is only possible when the protective cover is properly attached.
