GfM fan integrated condition monitoring system

GfM 2019 - fan integrated condition monitoring system 07 - 02 today to share with you the advanced automation, intelligent, integrated wind turbine condition monitoring system. GfM German company will be advanced machine diagnosis technology is applied to condition monitoring systems, intelligent algorithm to automatically search order spectrum and the envelope order spectrum, to find matching with possible damage model of frequency of significant peaks, realize the automation and intelligent condition monitoring system. Basically, this makes any one person could machine diagnosis of workers. The condition monitoring system covers an off-line and on-line system. Integrated online condition monitoring system based on Beckhoff platform development to provide customers with highly flexible and reliable solutions. According to the characteristics of the wind power industry and the demand, GfM provides three monitoring system: blades and fan blade bearings, transmission chain based condition monitoring system. Blade variable propeller blade bearing load bearing monitoring system very big cyclic loading, and between the rolling element and bearing ring rolling motion is relatively low. Blade abrasion on the surface of the bearing of the bearing is usually not obvious, and it cannot be detected by the traditional vibration diagnosis method. Normally, the state of the blade bearing mostly through the oil sample analysis or remove after inspection. GfM developed low drive diagnostic method for assessing blade bearings. Using the blade bearing nearby sensors for data acquisition. Measurements to assess inner ring, outer race and rolling elements of local damage. Transmission chain wind turbine condition monitoring system is usually designed service life of 20 years. They are affected by the specific load, however, that is why the transmission chain of the parts cannot be in the absence of maintenance measures to achieve the service life. In order to achieve good results, the most important thing is to implement based on state of maintenance. Condition monitoring system in wind turbine transmission chain deployment can timely found the following anomalies: rolling bearing damage and main bearing unbalanced; Gear box on the gear and bearing damage; Rolling bearing damage and generator imbalance; No fault. Through the state monitoring, usually can achieve in a few months before the actual critical conditions detected damage. So you can: long-term plans and organization, personnel, and auxiliary tools maintenance; Timely targeted procurement of spare parts; To shorten the maintenance time and can be arranged during the low wind speed. GfM transmission chain condition monitoring system with high sampling rate, the resampling the real-time order analysis, through the characteristic frequency pattern recognition on-line monitoring, automatic judgment damage and USES the alarm message text. The unique patented algorithm under the rated power of the variable speed wind turbine and reliable automatic fault diagnosis. Free vibration analysts workload, the realization of the automatic and intelligent vibration monitoring. Fan fan base installation components based condition monitoring system movement is the result of the load effect. Based monitoring system using the displacement sensor and strain sensor can measure all 24-hour online operation. Integrated state monitoring system based on the Beckhoff PC control technology platform, can the independent operation condition monitoring, condition monitoring system can be integrated into the fan control system, realize integrated solutions. GfM condition monitoring system automation advantages each subsystem can be independent, also can be integrated into a system. （ Source: the wind electric control)
