Centrifugal Compressor Surge Explained

Centrifugal Compressor Surge Explained FAQ

What causes surging in a centrifugal compressor?

Compressor surge occurs when the pressure of air delivered by the compressor is higher than the pressure that the compressor can maintain. A turbocharger is a centrifugal compressor that increases air flow, which produces more horsepower. Because surging occurs when the turbocharger is producing too much air flow,...

What is centrifugal compressor and how does it work?

A centrifugal compressor is a type of dynamic compressor , or turbocompressor, with a radial design. Unlike displacement compressors that work at a constant flow, dynamic compressors work at a constant pressure and the performance is affected by external conditions such as changes in inlet temperatures. So, how does a centrifugal compressor work? Air is drawn into the center of a rotating impeller with radial blades and is pushed toward the center by centrifugal force .

What is surging and choking in centrifugal compressor?

Choking: There is an unstable limit of operation of Centrifugal and axial flow compression,known as surging.surging is caused due to unsteady,periodic and reversal of flow through the compressor,when the compressor has to operate at less mass flow rate than a predetermined value.

What causes surge in a compressor?

What Causes Compressor Surge? Driver failure, Misdistribution of load in the compressor Power failure, Restrictions in the inlet and outlet of the system Upset process conditions, Inadvertent loss of speed Startup & shutdown problems, Failure of anti-surge mechanisms, Check valve failure, Very high rotation speed and insufficient flow More items...
