摘要： A turbomachine that includes a radial-flow impeller and one or more of a variety of features that enhance the performance of machinery in which the turbomachine is used. For example, when the turbomachine is used in a dynamometer, the features enhance the useful shaft horsepower range of the dynamometer. One of the features is a variable-restriction intake that allows for adjusting flow rate to the impeller. Other features include a unique impeller shroud and a shroud guide each movable relative to the impeller. Yet another feature is an exhaust diffuser that facilitates an increase in the range of shaft power and the reduction of deleterious vibration and noise. The turbomachine can also include a unique impeller blade configuration that cooperates with the adjustable intake and the exhaust diffuser to enhance flow through the turbomachine.

摘要： 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.
