Maintenance becomes predictive maintenance
Predictive maintenance is a new and important trend. Predictive maintenance is a technique in which data analysis and machine learning are used to predict the condition of machines or systems and identify maintenance requirements at an early stage. Predictive maintenance helps to avoid breakdowns and unforeseen downtime by enabling maintenance measures to be planned in good time and targeted repairs to be carried out. By monitoring sensor data and other relevant information, patterns and deviations can be detected to identify potential problems or wear and tear in good time. This enables companies to reduce costs for unplanned downtime and improve the efficiency of their systems.
In conjunction with continuous system monitoring (Condition Monitoring), which provides a prediction of wear and tear and the condition of the system, enables predictive, plannable maintenance. This allows faults to be detected at an early stage, system availability to be increased and maintenance costs to be reduced.
Continuous machine monitoring is already a routine requirement for system manufacturers and operators. For this purpose, sensor data is continuously recorded, stored in an intelligent database system and evaluated in real time. Older generations of systems with a wide variety of interfaces can also be retrofitted and connected to powerful data loggers such as the Expert Logger connect.
Using experience from continuous system monitoring
- Vibration monitoring: Gearboxes, bearings and shafts, e.g. in generators and turbines, are systematically monitored and alarms are automatically triggered. Shaft vibration analysis can also be used to monitor rotating shafts with plain bearings. With a frequency analysis of even very large amounts of data Expert Vibro devices The new technology enables us to determine the causes of unusual vibration phenomena.
- Process high-resolution long-term data online: Due to the long-term monitoring of vibration and process data, very large amounts of data must be recorded, stored and immediately evaluated online. Intelligent data acquisition devices with software channels (virtual channels) enable the creation and evaluation of high-resolution frequency spectra (FFT), which can provide important information about the system status.
- Connect vibration and process data: Thanks to data acquisition with 24-bit resolution and sampling rates of up to 50 kHz per channel, Delphin systems are able to record and intelligently evaluate vibration and process measurement values such as temperature data in one system in a time-synchronized manner. This enables faster and more reliable diagnostics.
- Connection to the control technology: Interfaces such as PROFIBUS, Modbus TCP or OPC UA are available for data exchange. The system monitoring can be integrated into the existing process control technology on request.
Step-by-step expansion to predictive maintenance
- Analyze complex relationships: For predictive maintenance, very complex connections must be analyzed in large amounts of data. Specific algorithms must reliably recognize correlations and patterns. This requires in-depth application knowledge and extensive measurement technology expertise.
- Extend condition monitoring: A system monitoring system that has already been introduced can be gradually expanded into predictive maintenance. As a first step, pre-engineering by Delphin provides an assessment of the evaluation options and serves as the basis for the required application development, which Delphin also supplies from a single source.
