Expansion Vessel Training Panel

Technical Description

Using this trainer the function of a normal expansion vessel is examined and a pressure-volume characteristic recorded. The expansion vessel is filled with water from a supply tank.

The pressure is generated using a small compressor and adjusted using a pressure regulating valve. The amount of water taken up by the expansion vessel is read on a scale on the supply tank.

Learning Objectives / Experiments

- Function and operation of a diaphragm expansion

vessel
- Displacement volume of an expansion vessel as a

function of the pressure
