We built a water brake years ago but want to build an electro-magnetic eddy current design that is more mobile and compact. 400 HP 800 HP 2000 HP.

Normally they are operated in 4 stages 2 coils either side for stage 1 4 coils either side for stage 2 so on.

. Most all designs out there are using either the Klam or Telma power absorbers for truck drive lines. An 8 pound absorber handles over 65 continuous Hp at 12000 RPM. I believe how it works is the moving vanes inside the brake are close fitting to the stationary vanes and when water is introduced the fricition starts- more.

The larger pump and water circuits handle the increased water needed to load even the largest of power engines. Water Brake Engine Dynamometers - 35X-Series 7350506 35X06 Water Brake Engine Dynamometer Shown. A water brake is a type of fluid coupling used to absorb mechanical energy and usually consists of a turbine or propeller mounted in an enclosure filled with water.

The first known toroid water brake was used to absorb 20000hp at 90 friggin rpm. How to Get More Results Out of Your water brake absorber design. Just leave the engine at wide open throttle and go through the RPM range by adjusting the braking force.

There are patents as far back as the early 1800s for this type of device the first one designed by William Froud to induce a load on a steam ship a big one too. The second one is a device named retarder which is normally used on the trucks to slow-them down on steady slopes. Pre-machined mounting plates fit popular GMFord bell-housing patterns may be custom drilled.

HTMLEmbedded Content The goal of your brochure may possibly vary from company to organization. The water brake acts as a very inefficient pump absorbing the energy produced by an engine. Toroidal-flow absorbers couple to engine either via the docking-stations telescoping driveshaft or the mobile-stands heat-treated 1-38x10-spline input shaft and your clutch disk or heavy-duty dampened drive plate.

Smooth Quiet Control With E-Stop Capability The Positorq Oil Shear Absorber brakes are a unique design for continuous tension control The unique Oil Shear Technology provides extremely smooth ultra quick response negligible wear with no adjustment required high energy Brake Engagement. From Absorbers Water-Brake. The shock caused by the acceleration of the water as it passes from pockets in the stator to the pockets.

YourDyno can acquire the data during a run and supports both manual and automatic brake control. The more water flowing through the dyno the greater the braking force exerted on the device under test. Through-shaft design allows either end of the dynamometer to be driven and.

Its fed by a 12 line and the output of the water brake just runs out of the brake onto the floor and goes into a drain. Equipped with grease-lubricated high-speed bearings. Heat-treated input shaft couples the mobile stands absorber to your engines.

Trunnion Engine Dynamometers variations. - Air-Cooled Eddy Current Absorber. Think about that for a second and let it sink in.

Water Brake Absorbers. Full-bridge strain-gauge load cell. It is a water brake.

This type of absorber is widely used in dynamometer testing of various applications due to its relatively inexpensive and power-dense design. The final design became an open loop water brake absorber system. Ad Our Products Support Many Market Sectors Contact Us Today To Learn More.

Early Superflows did have the open rotor design and are very capable of good results on small engines. By comparison a 300 pound air-cooled eddy-current absorber with the same continuous power rating is only good to 7000 rpm. Such applications include the bench testing of motorcycle automotive.

A casing houses the impeller type water brake. There is a good paper titled Design development of Dynomometer water absorber by Karlis Banis. For the dyno i will wire all the coils together.

Brakeabsorber dynos works by braking the engine and measuring the force torque it takes to brake it over the RPM range. As the turbine or propeller turns mechanical energy is transferred to the water due to turbulence and friction. Design and a water brake based on the legendary SuperFlow design SF-4000HD provides reliable testing for 4000HP engines at speeds up to 12000 RPM.

Water Brake Dyno Advantages include. Some are intended to Exhibit providers While Many others are focused on providing an concept. In essence the fluid flow in the two designs are almost identical with the cupped design being more efficient.

We have been shopping for a year trying to snag some. The paper investigates the effect of several design parameters of a dynamometer water absorber brake. For applications that do not require stall speed loading an air-cooled.

There is a stationary side stator and a spinning side rotor each with cup shaped pockets that transfer water from one side to the other. Air-Cooled Eddy Current Absorbers offer load-control response times measured in milliseconds moderate inertia and high specific load capacity especially in the lower RPM working ranges of most industrial-type engines. Ideal for a wide range of markets water brake engine dynamometers churn water inside the housing and transfers energy by momentum exchange and water shear.

Water brake dynamometers use a hydraulic brake that converts the energy produced by the engine into heat transferred to the water flowing through the dynamometer. As engine speed increases the water brake rotates. Building another chassis dynamometer.

These trunnion-mounted fixed-base Water. Power capacity versus size of a water brake is impressive. 9 toroid Siamese Trunnion style water brake absorber S-Beam Load Cell DYNOmite-Pro data-acquisition computer manual load valve 28-channel data harness stainless braided hoses with aircraft fittings and manual.

It doesnt take very much water at all. Many other water brake AC or eddy-current absorber combinations are available to test from 1 to over 10000 Hp Optional 3000 Hp toroidal-flow absorber responds twice as quickly as ordinary vane-type brakes. The resistance in each coil is 0945 ohms.

It is no wonder that water brakes are virtually the only choice for testing 2000 horsepower drag car engines. Need for disassembly of the absorber. There are 8 coils either side of the stator 16 in total.

The impeller is directly connected to the driveshaft of the test engine. The first one is a water-brake absorber generally used as a dynamometer to measure the torque of car-engines on a test bench. Bigger bearings new high RPM seals easy access servicing and plenty of other features.
