Description:
Compact, bench top apparatus to demonstrate the principle of operation of various centrifugal force governors. A motor driven vertical shaft has a chuck mounting which allows the easy attachment of the three governor mechanisms supplied. The shaft is speed controlled
with the speed displayed on the front panel.
Three governors are supplied: Porter, Proell and Hartnell. Each governor is fully assembled, ready for testing. The Porter and Proell governors incorporate governor masses that can be removed to vary the rotating mass. Sleeve weights can also be added to these two governors using the slotted weights provided. The slotted weights are profiled not to come off during testing.
Experimental Content:
- Geometry and operation of a Porter, Proell and Hartnell governor
- To observe the lift off speed of the three different types of governor
- To observe the stability of a governor
- To observe the affect of varying sleeve weight or spring force on the operation of a governor
- To compare actual results with calculated theoretical values
Technical Specification:
- Porter governor radial travel range: 80-100mm
- Proell governor radial travel range: 75-100mm
- Hartnell Spring rates: 0.39N/mm and 0.97N/mm
- Porter and Proell Sleeve masses: 58g
- Porter and Proell masses:157g
- Hartnell masses: 118g
- Hartnell mass adjustment range: 20mm
- 3mm increment indications on vertical shafts
