A small-scale multi-stage centrifugal compressor demonstration unit, comprising of an inlet duct, the compressor, an outlet duct and an adjustable aperture, all mounted on a stainless steel base.

Seven stages in the compressor.

Equipped with electronic measurement sensors for head pressure, flow-rate (via orifice plate) and air temperature.

Capable of being linked to a PC(not supplied) via a dedicated interface console (an essential accessory).

Supplied with software providing full instructions for setting up, operating, calibrating and performing the teaching exercises. Facilities for logging, processing and          displaying data graphically.

Full theoretical back-up together with a student questions and answers session

Instructional capabilities:

Measurement of constant-speed machine performance in terms of static and total pressures, rotor speed and motor shaft power, as a function of inlet flow

Measurement of compressor efficiency and estimation of impeller power efficiency

Measurement of performance at constant speeds

Introduction to similarity laws for scale-up

Comparison of student calculations with computer results
