Abstract
A modular waterbrake that can be used with differing types and sizes of rotating machines includes common end stages, and a plurality of common intervening power stages. Each power stage will extract a certain amount of shaft horsepower from the machine under test, and each stage operates independently of one another. Thus, the modular water dynamometer can be used to zero in on desired torque test loads during machine testing, by simply activating or deactivating selected stages.
Claims42
A water dynamometer, comprising:
- a channel housing having a fluid inlet, a fluid outlet, and a flow channel formed therein, the flow channel fluidly coupling the fluid inlet to the fluid outlet;
- a stator ring disposed at least partially within the channel housing and having a first side, a second side, an outer peripheral surface, and an inner peripheral surface, the stator ring outer peripheral surface having a plurality of fluid inlet ports in fluid communication with the channel housing fluid inlet port, and the stator ring inner peripheral surface having a plurality of fluid outlet ports in fluid communication with the stator ring fluid inlet ports;
- a first end rotor and a second end rotor disposed adjacent the stator ring first side and second side, respectively, each end rotor including a plurality of rotor vanes disposed on a surface thereof and in fluid communication with the fluid outlet ports of the stator ring inner peripheral surface.
A modular water dynamometer, comprising:
- two or more channel housings coupled together, each channel housing having a fluid inlet, a fluid outlet, and a flow channel formed therein, the flow channel in each fluid channel housing fluidly coupling its associated fluid inlet to its associated fluid outlet;
- two or more stator rings, each stator ring disposed at least partially within at least one of the channel housings and having a first side, a second side, an outer peripheral surface, and an inner peripheral surface, the outer peripheral surface of each stator ring having a plurality of fluid inlet ports in fluid communication with its associated channel housing fluid inlet, and the inner peripheral surface of each stator ring having a plurality of fluid outlet ports in fluid communication with the fluid inlet ports of its associated stator ring outer peripheral surface;
- one or more intermediate rotors, each intermediate rotor disposed between two of the stator rings;
- a first end rotor disposed adjacent the first side of a first one of the stator rings;
- and
- a second end rotor disposed adjacent the second side of a second one of the stator rings.

A modular water dynamometer, comprising:
- a housing;
- two or more channel housings disposed within the housing and coupled together, each channel housing having a fluid inlet, a fluid outlet, and a flow channel formed therein, the flow channel in each fluid channel housing fluidly coupling its associated fluid inlet to its associated fluid outlet;
- two or more stator rings disposed within the housing, each stator ring disposed at least partially within at least one of the channel housings and having a first side, a second side, an outer peripheral surface, and an inner peripheral surface, the outer peripheral surface of each stator ring having a plurality of fluid inlet ports in fluid communication with its associated channel housing fluid inlet, and the inner peripheral surface of each stator ring having a plurality of fluid outlet ports in fluid communication with the fluid inlet ports of its associated stator ring outer peripheral surface;
- one or more intermediate rotors, each intermediate rotor disposed within the housing between two of the stator rings;
- a first end rotor disposed adjacent the first side of a first one of the stator rings, and disposed at least partially within the housing;
- a second end rotor disposed adjacent the second side of a second one of the stator rings, and disposed at least partially within the housing;
- two or more fluid supply conduits coupled to the housing, each fluid supply conduit having a fluid inlet port and a fluid outlet port, the fluid supply conduit inlet ports each adapted to couple to a working fluid source, the fluid supply conduit outlet ports each in fluid communication with one or more stator ring fluid inlet ports;
- and
- a valve mounted on each fluid supply conduit, each valve moveable between an open position and a closed position, whereby working fluid from the working fluid source is selectively supplied to each stator ring fluid inlet port.
