This M test chart, supports performance testing of vehicle-mounted air pumps (such as air tightness, pressure stability, and inflation efficiency) as well as compliance testing for certifications (such as CE, FCC, and UL). Its modular design can be adapted to different specifications of air pumps, meeting the full-cycle testing requirements from R&D to mass production.
Core functional modules
1. Airtightness Test
Leakage points are detected using a transparent sealed tank combined with the soapy water method, with real-time monitoring of pressure changes, achieving an accuracy of ±0.5%. It supports the setting of pressure holding time and pressure difference range (such as determining as qualified within ±1% error).
2. Pressure and Flow Rate Test
The pressure range covers 0 to 2 MPa (customizable up to 1500 kPa), and the flow rate test reaches 200 m³/min, meeting the requirements of different air pump specifications. It integrates a hot-wire anemometer and pressure transmitter to achieve high-precision data collection (wind speed error ±3%).
3. Durability Test
It simulates on-off cycles (such as power on/off, solenoid valve action) and records the performance degradation of the air pump during long-term operation. It supports custom cycle counts (such as 5000-hour life verification).
4. Electrical Performance Test
It monitors parameters such as working current (0-1000 mA), voltage, and power, and supports over-limit alarm and automatic shutdown. It complies with electrical safety standards such as UL1450 and EN60335, and supports ground resistance and leakage current detection.
5. Intelligent Monitoring and Data Analysis
It is equipped with an MCU and industrial control system, which can display curves of flow rate, head, temperature, etc. in real time, and supports data storage and historical playback. It generates PDF/Excel reports, compatible with print output, facilitating production traceability and certification application.

13. Communication interface: Supports CAN bus, 5G remote control (for some high-end models).
14. Sensor types: Hot ball anemometer, pressure transmitter, microphone (noise detection).
Product Advantages
1. Modular Design
Adaptable to different air pipe sizes, the adjustable arc-shaped fixture resolves interface compatibility issues. The split structure facilitates maintenance and upgrades, and supports multi-channel synchronous testing (such as 3-channel parallel testing).
2. Intelligence and Automation
The fuzzy PID algorithm dynamically adjusts the inflation rate, reducing human intervention. An integrated fault warning system predicts potential faults through noise and vibration analysis.
3. High Precision and Reliability
Compliant with ISO 7637-2 automotive electronic anti-interference standards, ensuring test stability. The soundproof box design (patented technology) reduces environmental noise interference during testing.
Application scenarios and industry value
Product development and verification: Optimize the inflation efficiency of air pumps (e.g., reduce the inflation time from 0 to 250 kPa to 90 seconds).
Production quality inspection: Batch testing of the sealing performance and motor lifespan of air pumps (e.g., the lifespan of ceramic piston cylinders reaches 5,000 hours).
Certification testing:
EU CE certification: Pass EMC (EN 55014) and LVD (EN 60335) tests.
US UL certification: Complete electrical safety, mechanical strength, and environmental adaptability tests in accordance with UL1450 standards.
FCC certification: Support electromagnetic compatibility testing (FCC SDOC process).
Compliance for cross-border e-commerce
Meet the mandatory certification requirements of platforms such as Amazon and Temu for car air pumps (e.g., UL reports, RoHS testing).
