Description

Technical Field

[0002] In power plant oil particle size testing, air bubbles in the oil are often misidentified as particles, leading to data distortion, particle counting errors, and the impact of bubble bursts on detection stability due to localized turbulence. Furthermore, bubbles adhering to the sensor surface can create blind spots. Current oil particle size testing methods typically employ settling and centrifugation. Settling takes several hours, failing to meet the demands for rapid testing; centrifugation disrupts the original particle distribution of the oil sample; and manual vacuuming is complex and prone to secondary air bubble aspiration, interfering with the results.
