Industrial Classification In A New Impeller Wheel

Nov 01, 1999 2.. Theoretical backgroundThe efficiency of air classification is influenced by different parameters such as centrifugal force, drag force, particle concentration and flow conditions including the inlet and outlet areas .Due to a minimum of momentum exchange between air and solid phases, the centrifugal counterflow air classifier has a high sharpness of cut.

A Machine Learning Approach To Classification Of Gas

Dynamic pressure data for training and testing the classification algorithms is generated using simulated and experimental methods. The binary MLP model predicts gas entrainment exceeding a 2% void fraction of air with 90% accuracy, and radial wear exceeding 1.5% of the impeller diameter with 97% accuracy.

impellers the air comes into the fan parallel to its axle (or already with angular momentum), then it flows onto a plane perpendicular to the inlet- axle. This stream does not continuoue the flow along the radius after this direction-change, but it let develop different bended flow lines between the blades on perpendicular planes to the inlet-axle.

Use a pump with a larger, impeller eye opening. Use several smaller pumps. Three half capacity pumps can be cheaper than one large pump plus a spare. This will also conserve energy at lighter loads Air ingestion (Not really cavitation, but acts like it) A centrifugal pump can handle 0.5% air by volume. At 6% air the results can be disastrous.
