Research on Influence of Turbine Oil Bubbles on Oil Condition Monitoring

Turbine oil is very easy to generate a large number of air bubbles in the process of operation. Air bubbles not only have a great impact on the quality of oil and the operation of machinery, but also have a great impact on the reliability of oil online monitoring, resulting in monitoring data errors. Therefore, it is necessary to analyze the influence of air bubbles in the oil on the monitoring parameters. In this study, the dielectric constant sensor, particle contamination sensor, particle number sensor and viscosity sensor were used to study the changing law of the influence of bubbles on various characteristic parameters of oil, and make a qualitative analysis. And under the experimental conditions, the influence of temperature on the physical and chemical indicators was excluded by the temperature control method. The experimental results show that the number of air bubbles will affect the oil, and the more air bubbles, the worse the performance of the oil.
