Vibration Measurement and Analysis
Vibration measurement - What is it?
- Vibration measurement and analysis is a reliable and optimal tool for condition-based maintenance in order to evaluate the condition of machinery and aggregates.
- Data on the condition of vibration of a motor or aggregate is collected continuously or periodically during operation and recorded. Conclusions regarding the mechanical condition can be drawn from this analysed or evaluated data.
- The following can be identified:
damage caused by storage, imbalance, alignment errors (nonalignment), magnetic asymmetry, electrical faults in the rotor or motor winding, resonance faults. etc.
Vibration measurement - Where and how is it used and what are its benefits?
- On all rotating machinery and aggregates
- Measurements are taken on predefined machine positions whereby the assembly of the measuring probes can be either mobile or permanently fixed.
- The measuring data can be recorded online or offline as well as periodically or manually using a data collector. According to the type of data collection, it can then be transmitted, edited and processed by computer or analysed.
- Vibration measurement allows the measuring and recording of vibrations well before they are noticeable or audible.
- A conclusion on the cause of looming faults and their implications can also be drawn based on the evaluation or analysis of the data. Subsequent trend measurements enable the calculation of the remaining service life or wear margin of the affected component.
- Identification of faults and weak spots at an early stage (in the formation phase); minimisation of unscheduled equipment downtime (due to identification of faults at an early stage); increasing availability of equipment and productivity (due to predictable maintenance); minimising maintenance costs (due to almost no unpredicted failures or optimising the assignment of maintenance resources)
Vibration measurement - When and how often?
- After new construction, modification or renovation of machinery, motors and aggregates for documenting an accurate and contiguous first start-up.
- After new construction, modification or renovation of machinery, motors and aggregates as evidence of a suspected faulty assembly
- To determine the actual condition or record the condition (also as evidence for quality control)
- Test cycles:
These are to be observed individually as they depend on equipment load, load change, operating mode, etc.
