Industrial Retarder (Hydrodynamic Brake) for Simulating Various Load Conditions of Diesel Engines
15 March 2004 15:26
The first units have already been delivered for use on the training stand at the German Navy's Parow Marine School.
At Parow Marine School, diesel engines are operated under quasi-realistic conditions, in order to teach the cadets how the engines function.
After all, the ship's crew needs to be fully familiar with the technology in the machine room and know how a drive reacts under certain load conditions.
The VIR 133-2-S retarder simulates a load that closely resembles that of a marine drive with propeller.
For this application three hydrodynamic brakes are activated successively and connected to the diesel engine.
This is the only way of braking the maximum output of over 1200kW.
Varying load situations can be achieved by five different propeller curves that are preprogrammed in the electronic control unit: full sail, three reduced sailing speeds, and idling.
Further characteristic curves can be programmed in line with customer specification.
Although load simulations could also be achieved with braking systems from competitors, as Voith Turbo solution uses standard components it is much more cost-effective and requires less space because of its compact design.
Another advantage: after only minor modification, the industrial retarder can be turned into a tailor-made solution for a wide range of applications (such as diesel engine test stands).
Thanks to its wear-free braking effect, the Voith industrial retarder can also be used as a "hydrodynamic idler" in the long lever systems of oil pumps or as a brake for downhill conveyor belts.
