The Use Of Engineering Thermoplastics For Centrifugal Compressor Labyrinths.
Abstract
The use of engineering thermoplastics is increasing rapidly in today's turbomachinery industry. The primary use of these thermoplastics has been as a material upgrade from aluminum for centrifugal compressor labyrinths. With proper application, substantial compressor efficiency improvements can be achieved by lowering seal leakage. Other benefits include increased reliability by reducing shaft damage during hard rubs and by allowing an alternate material selection for applications where the existing aluminum is attacked by the process. These aspects of the thermoplastic's application are addressed. Other materials used for their abradabilty properties (such as TFE) will not be covered.
