More Information
Summary:A fluid-type absorption dynamometer that includes a rotary impeller and one or more of a variety of features that enhance the shaft-horsepower range for which the dynamometer can be used. One of these features is a variable restriction intake that allows a user to adjust the flow of fluid to the impeller. Other features are a unique impeller shroud and shroud guide that are each movable relative to the impeller to allow a user to adjust flow characteristics at the exhaust and blade regions of the impeller. Yet another feature is a set of exhaust baffles that facilitate an increase in the range of shaft power ratings of the device and the reduction of deleterious vibration and noise. The dynamometer also includes impeller blades having a unique configuration.
