More Book Details

Description of the Book:

Two 3000-psi (20,700,000 Pa) hydraulic pumps, designed using the principles of the scroll mechanism, were built and evaluated to determine their feasibility for future shipboard hydraulic service. This report presents the geometry, mathematical models, and machining techniques required to fabricate these prototypes. The first-generation pump demonstrated a 95 percent volumetric efficiency at 500 psi (3,400,000 Pa), while the improved synchronously rotating drive mechanism of the second-generation unit eliminated the vibration and balance problems of the first-generation orbiting drive arrangement. This report also presents recommendations for follow-on scroll pump work. However, based on the results to date, the program has been suspended, pending evaluation of other Navy pump concepts.
