Filter Dynamic Cycling Tester
Applications
Mainly used for performance testing of filter elements (such as hydraulic oil filter elements, fluid filtration filter elements, etc.):
1. Evaluating the chemical element precipitation characteristics of filter elements under long-term dynamic cyclic conditions;
2. Testing the durability of filter elements under repeated dynamic stress cycles and predicting their fatigue life;
3. Assisting in the quality inspection, performance verification, and research and development improvement of filter elements.
Standards
(1) ISO 23840 — Hydraulic fluid power — Filters — Evaluation of filter performance using multipass test.
(2) JB/T 7857 — Performance test of hydraulic filter elements.
(3) ISO 2942 — Hydraulic fluid power — Filter elements — Verification of fabrication integrity.
(4) GB/T 14041.1-1993 — Hydraulic filter elements — Structural integrity test methods.
(5) ISO 4003 — Permeable sintered metal materials — Determination of fluid permeability.
(6) GB/T 5249-1985 — Permeable sintered metal materials — Bubble test method for pore size determination.
(7) QC/T 794-2007 — Filter paper for internal combustion engines.
Features
1. Specialized Functions: It can test the chemical element precipitation characteristics of filter elements under long-term dynamic cycling, and simultaneously evaluate the durability of filter elements under repeated dynamic stress cycling and predict fatigue life.
2. Intelligent Control: Utilizing touchscreen operation + PLC control, it can automatically identify and alarm abnormal states during the test process, offering convenient operation and stable performance.
3. Comprehensive System Configuration: Includes a circulation system (variable frequency pump set, temperature control/stirring components), a real-time temperature control system (temperature control accuracy ±2℃), and an industrial-grade electrical system, with clearly defined functional modules.
4. Lightweight Structure: The test bench frame is made of high-strength industrial aluminum profiles, combining the advantages of light weight, high strength, and aesthetic appearance.
