640KW 2800rpm Heavy Duty Engine Dynamometer
SDHD 640-800KW 2800rpm ±0.5%FS Heavy Duty Diesel Engine Test System
Overview
SDHD dynamometer is a new generation of universal product series for heavy duty diesel engine test and other high torque mechanical equipment test. SDHD has two different cooling forms: air cooling and water cooling, and the two cooling forms are based on the same main structure. SDHD dynamometer has rich expansion options: for example, different bearings can be selected to expand the speed range.With seelong engine test control system, SDHD can complete the whole performance test of heavy diesel.
Advantage
- High power density, compact structure and small volume
- Wide controllable speed range
- High flexibility benefits from the following options:
- Air cooled or water cooled
- Flexibility of mechanical structure design
- long life bearing
- High rotational accuracy, even at very low speeds
- Maximum heat load utilization covers the entire speed range
- Low noise
Engine Test Systems
The engine development process must rise to the challenge of the increasing vehicle complexity. Additional actuators, integrated support systems, more stringent emission laws with regional differences like the introduction of real driving emissions RDE requirements in Europe, new technologies and the ongoing rise in electrification – these are all have a bearing on work of the development engineer. SeeLong continuously searches for new solutions as well as intelligent methodologies and develops numerous state-of-the-art tools which are integrated in the test system and made available to the developer.
