Hydraulic oil purification and filtration tester
Meet the standard:
ISO 16889
ISO 4406
ASTM D7619
ISO 11500
Product Introduction:
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).
The instrument is used for:
Evaluating the particle removal efficiency (Beta ratio) and dirt holding capacity of new and in-service hydraulic filter elements.
Comparing the performance of different filter technologies and manufacturers.
Assessing the effectiveness of oil purification systems (vacuum dehydrators, coalescers, absorbent filters) in removing water and dissolved gases.
Monitoring the cleanliness level of hydraulic fluid before and after filtration or purification.
Research and development of advanced filtration and purification media and systems.
Quality control for manufacturers and users of hydraulic filters and purification equipment.
