Hydraulic Downpull Forces on Powerhouse Intake Gates. Ice Harbor Dam, Snake River, Washington: Hydraulic Model Investigations
Measured hoist loads due to hydraulic downpull on powerhouse intake gates at Chief Joseph Dam were about twice as large as expected. For this reason model studies were necessary to determine the most practical gate bottom shape and the maximum hydraulic downpull to be considered when designing powerhouse intake gate hoists for Ice Harbor Project. Because prototype data were available, a typical intake, intake gate, penstock, and scroll case for Chief Joseph powerhouse were reproduced for a series of preliminary tests. The pattern and magnitude of downpull forces on the prototype intake gates were duplicated in the 1:25-scale model. Hydraulic forces on an intake gate in motion (closing) were compared with those for various openings of a stationary gate.
