Abstract
An apparatus achieves passive damping of flow disturbances to control centrifugal compressor surge. The apparatus includes a centrifugal compressor for compressing a low pressure fluid. The centrifugal compressor has an impeller, an inlet which communicates with an atmosphere and a discharge through which compressed air is supplied to a compressed air system. A fluid flow control is flow connected with the inlet for controlling the flow of a low pressure fluid to the compressor. A check valve is flow connected with the discharge for preventing high pressure fluid from back flowing to the compressor. A vane diffuser assembly fluidly communicates with the impeller. A spring-mass-damper system is coupled to any one or all of the fluid flow control, check valve or vane diffuser to dampen low amplitude flow disturbances of the compressible fluid.
