Filter element dynamic cycling test bench is mainly used to test the chemical element precipitation characteristics of filter element under long-term dynamic cycling. It adopts touch screen operation mode, combined with PLC control, according to the setting line, and can analyze and judge the abnormal state in the test process and send out alarm information. Manual interval sampling and analysis.
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.
