HEENAN AND FROUDE HYDRAULIC DYNAMOMETER PDF

The EC absorbers provide a quick load change rate for rapid load settling. Most are air cooled, but some are designed to require external water cooling systems. Eddy current dynamometers require an electrically conductive core, shaft, or disc moving across a magnetic field to produce resistance to movement. Iron is a common material, but copper, aluminum, and other conductive materials are also usable. In current applications, most EC brakes use cast iron discs similar to vehicle disc brake rotors, and use variable electromagnets to change the magnetic field strength to control the amount of braking. The electromagnet voltage is usually controlled by a computer, using changes in the magnetic field to match the power output being applied.

Meshicage It was reviewed on 13 April by FlickreviewR and was confirmed to be licensed under the terms of the cc-by Delivery times may vary, especially during peak periods. The Froude F-series range of hydraulic dynamometers also referred to as water brakes have been anr to be compact, robust and to allow easy maintenance. Thank you for Looking and Have a Great Day 5. Phil Sangwell from United Kingdom. A hydraulic dynamometer of the type referred having a pair of sluice gates sliding between the vaned elements for controlling the power capable of being absorbed by the dynamometer, said sluice gates being formed with rounded leading edges and having apertures therein for the passage of liquid to the space behind. The dynamometer working compartment consists of special semi-circular shaped vanes cast froudw stainless steel rotors and stators. To attain this object according to the invention the parts vroude the dynamometer with which the working liquid comes into contact with a high velocity are so shaped that the liquid will flow over the surface dynamkmeter smoothly and without generating appreciable turbulence.

FROUDE IS A WELL KNOWN ENGINE DYNAMOMETER MANUFACTURER

It is well known that when dynamometers of this type are employed for testing or other purposes involving the destruction of considerable amounts of power, the relative velocity between the water and the apparatus is sufficiently high to endanger the life of the working parts by erosion or by erosion-corrosion and it is the object of the present invention to reduce damage to the working parts by avoiding, as far as possible, the creation of harmful eddies in the vicinity of the vulnerable parts of the dynamometer. To attain this object according to the invention the parts of the dynamometer with which the working liquid comes into contact with a high velocity are so shaped that the liquid will flow over the surface thereof smoothly and without generating appreciable turbulence. The invention is illustrated in the accompanying drawings and will be described with relation thereto. In these drawings: Fig. The casing A is mounted so as to be capable of a slight oscillating movement and is connected to the measuring and weighing apparatus C by the arm C1. The water or liquid leaves the elements A2, B2 at the circumferential edge b2 from which is passes to the annular chamber bl connected to the outlet b. The power which the dynamometer is capable of absorbing is regulated by the sluice gates D which slide between the two vaned elements A2 and B2, the screws d by which they are operated being geared together so that the two gates will be 2 moved in or out in unison by a single operating handle.
