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
Features
Trainer on heating systems and plumbing
Function of an expansion vessel
Specification
Trainer on heating systems and plumbing
Small compressor for pressure generation
Measuring tank with scale
Expansion vessel
Manometer
Ball valve in connecting pipe between measuring tank and
expansion vessel
Adjustable safety valve
Pressure controller for air with overpressure protection
Cutaway model of an expansion vessel
