The Hydraulic Oil Purification Filtration Tester is designed to maintain and improve oil cleanliness in hydraulic and lubrication systems. You can use this device to remove solid particle contaminants through multi-stage filtration and bypass circulation, ensuring stable system operation and extending the service life of hydraulic components and the entire system. It supports both online purification during operation and offline oil regeneration during filling, oil replacement, or maintenance.
Application
You can apply this tester in various scenarios, including:
(1) Pre-cleaning of hydraulic oil during system filling;
(2) Online circulation filtration for hydraulic and lubrication systems;
(3) Bypass purification during equipment operation;
(4) Regeneration and cleaning of used hydraulic or lubricating oil;
(5) Routine maintenance of industrial hydraulic systems;
(6) Hydraulic systems in construction machinery, metallurgical equipment, injection molding machines, and machine tools;
(7) Oil management in power plants, mining, ports, and heavy-duty equipment.
Standards
You can operate this device in compliance with international and domestic standards:
(1) GB/T 14039 — Hydraulic transmission: Code for solid particle contamination levels in hydraulic fluids;
(2) GB/T 18854 — Hydraulic transmission: Automatic particle counting method for liquid contamination measurement;
(3) ISO 4406 — Hydraulic fluid contamination: Coding of solid particle contamination levels;
(4) ISO 4407 — Hydraulic fluid contamination: Measurement of particle contamination using optical automatic counters;
(5) NAS 1638 — Aerospace hydraulic system contamination levels.
