Compressor Wheel

详情

Compressor Wheel (TD**4) - Description: Compressor wheels or impellers are produced using a variant of the aluminum investment casting process. A rubber former is made to replicate the impeller around which a casting mold is created. The rubber former can then be extracted from the mold into which the metal is poured. Accurate blade sections and profiles are important in achieving compressor performance. Back face profile machining optimizes impeller stress conditions. Boring to tight tolerance and burnishing assist balancing and fatigue resistance. The impeller is located on the shaft assembly using a threaded nut. The turbine and impeller wheel sizes also dictate the amount of air or exhaust that can be flowed through the system, and the relative efficiency at which they operate. Generally, the larger the turbine wheel and compressor wheel, the larger the flow capacity. Measurements and shapes can vary, as well as curvature and number of blades on the wheels. Thanks
