Hydraulic oil purification and filtration tester

Introduzione del prodotto

Hydraulic oil purification and filtration testers are essential tools for characterizing the performance of fluid cleaning technologies. A common type of tester, particularly for evaluating filter elements, utilizes the multi-pass test principle (standardized by ISO 16889). In this method, contaminated hydraulic oil is continuously circulated from a reservoir, passed through the filter element under test, and returned to the reservoir. As the test progresses, solid particles are continuously injected into the reservoir, and fluid samples are taken from both upstream and downstream of the filter. An automatic particle counter analyzes these samples to determine the number and size distribution of particles. By comparing the upstream and downstream particle counts at different sizes, the filter's Beta ratio (a measure of efficiency) and dirt holding capacity (the amount of contaminant a filter can retain before reaching a specified differential pressure) are determined.

For evaluating purification systems (such as those for removing water or dissolved gases), testers may involve circulating oil through the purification unit and measuring the contaminant levels (water content via Karl Fischer titration or sensors, dissolved gases via gas chromatography or sensors) before and after the process. These testers provide crucial data for selecting appropriate filtration and purification solutions, monitoring their performance, and ensuring that hydraulic fluids meet required cleanliness standards (e.g., as specified by ISO 4406 cleanliness codes).
