Centrifugal Compressor Demonstration Unit

Specification:

• 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.

Instruction 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

Specification:

• Max Flow Rate: 20 l/s typical
• Max Head: 6.0KPa
• Max fan speed 3000rpm
