INVESTIGATION AND ANALYSIS OF THE PERFORMANCE CHARACTERISTICS AND FLOW CIRCULATION IN TEST MODEL REGENERATIVE PUMP

摘要

The momentum analysis, even with gross assumptions of linear momentum change causing the pressure buildup, yielded results that agree with the experimental results. The characteristic curves for the test model pump are similar to published curves for regenerative pumps. Therefore, this type of momentum analysis does provide an insight into the circulation and velocity pattern that exists in conventional regenerative pumps. The circulation is very important in this theory of momentum exchange, therefore further work should be directed toward controlling the circulation to yield the desired pump characteristics. The test pump impeller design with the toroid should be compared with regenerative pumps with conventional impeller design in actual tests with other factors equalized.
