An engine dynamometer (dyno) is a major investment and if not maintained properly it can perform less effectively, especially when you’re testing to the dynamometer’s capacity. Learn eight ways to maximize the life of your engine dyno to help deliver the best overall value in the form of lower downtime, superior performance and higher return on investment.
1. Optimize discharge water temperatures
High discharge water temperature causes impurities to form on the rotors and stators within your dynamometer, preventing full displacement of water. This is usually caused when the dynamometer reaches a high discharge temperature, typically over 175°F (79°C). When this occurs, impurities from the water build up internally in the dynamometer and begin filling the voids that are used to create dynamometer load. As these pockets fill, the dynamometer begins to reduce the amount of load to your engine, in turn making your dynamometer perform less effectively.
2. Have your water tested and/or install a Water Treatment and Filtration System
Contact a local water treatment facility to test your water. You’ll receive information on your water quality and what steps are necessary to improve your water quality and minimize calcification and scale within your water system. A Water Treatment and Filtration System is a synergistic, self-contained, chemical-free system that keeps your water and pipes clean. The system aids in removing the impurities by ionizing the water and collecting the sediment that can accumulate in the voids within the dynamometer. This system is a stand-alone product that includes a circulation pump separate from the water recirculation/cooling system. The Water Treatment and Filtration System will not interfere with the operation of your cooling tower.
3. Replace the packing on a regular basis to prevent poor sealing around the shaft
Packing material is used to maintain the water within the dynamometer. The packing requires replacing on a regular basis to prevent poor sealing around the shaft. The packing should always be moist. To maintain moisture, adjust the packing nut so...Click to read more >>
