AI Technical Summary

Technical Problem

During use, existing nitrogen springs may experience cylinder pressure exceeding or falling below normal operating pressure due to assembly errors and external environmental factors, affecting product quality. Furthermore, they lack an effective low-pressure alarm mechanism.

Method used

Design a low-pressure alarm display device integrated into the nitrogen spring inflation port, including components such as cylinder, plunger, vent valve, inflation valve, miniature piezoresistive sensor, buzzer, warning light and handwheel. Through the cooperation of scale and positioning block, the device enables direct observation of air pressure status and audible and visual alarms, ensuring rapid judgment and adjustment of air pressure.

Benefits of technology

It enables intuitive monitoring and alarm prompts for the nitrogen spring pressure status, improving maintenance efficiency and accuracy, reducing downtime, simplifying the inflation process, and reducing the risk of human error.
