EN9000 integrates the on-line monitoring and protection system (TSI) and fault diagnosis expert system (TDM+ES) and is mainly used for on-line vibration monitoring, protection, analysis and fault diagnosis of large mechanical equipment of the power sector, petrochemical industry, metallurgical industry, etc. such as steam turbine generator set, hydroelectric generator set, compressor unit, air blower, electrical motor, water pump, gear and bearing. This system could continuously gather state parameters related to the equipment safety, including key phase/speed, shaft vibration, casing vibration, axial displacement, differential expansion, eccentricity, and other procedural parameters. EN9000 hardware system adopts a modular structure; all sub-modules support Hot-Plug and could be configured or expanded flexibly in order to meet the requirement of diversified on-site supervision. EN9000's host machine (TSI) and the upper computer software system (TDM+ES) have a nice user interface. The upper computer software system could communicate with the host machines of more EN9000 and could form a remote monitoring diagnostic center through Internet.
- Flexible System Setup & Audio-visual Monitoring Displays: of each acquisition module directly in bar chart, figure, curve, waveform, spectrum and the orbit of shaft centerline.
- Data acquisition: : Continuous gathering of state parameters.
- Modular Structure: highly modularized, and the sub-modules support on-line Hot-Plug to ensure the independence of each module and ensure the failure-free operation of other modules when one goes wrong.
- Output: Each acquisition protection module is provided with high-precision buffering and 4-20mA transduced current output, facilitating the connection of secondary instrument, portable test system and DCS system.
- Screen display: Each acquisition protection module has a small LCD (white, green or blue back light) for direct display of current revolution and corresponding vibration value as well as some key internal data.
- High-reliable protection system : of parameters as speed, shaft vibration, casing vibration and axial displacement, modular structure, redundant power supplies and all modules support Hot-Plug.
- Alarm monitoring and protection
- Remote diagnosis and analysis as well as WEB service.
