Title : Centrifugal Compressor
Introduction: The equipment comprises of a 7-stage centrifugal compressor driven by an electric motor mounted on a support plinth. Clear acrylic inlet and outlet ducts are installed on the compressor to allow the air passing through the unit to be monitored.
Appropriate sensors are incorporated on the unit to facilitate analysis of the compressor performance when connected to a suitable microcomputer via an IFD Interface Console. In addition to the tappings required by the pressure sensors, additional tappings are included in the ducts to allow appropriate calibration instruments to be connected.
The flow of air through the compressor is regulated by a throttle control device installed at the exit of the discharge duct. Rotation of the collar opens and closes a variable aperture which allows the head/flow produced by the compressor to be varied.
