AI Technical Summary

⚠Technical Problem

Existing nuclear magnetic resonance spectrometers have simple and outdated gas supply protection systems in high-temperature and low-temperature experiments, with low automation, low nitrogen utilization efficiency, and potential safety hazards. Manual control of the switching valve opening and closing also poses risks.

⚗Method used

A large nitrogen storage tank is used as the gas supply source. The automatic control is achieved by switching the flow pipeline through the regulating valve group, which provides a stable nitrogen supply for high temperature and low temperature experiments. Humidity detection and dryer are installed in the gas pipeline to ensure gas quality.

🎯Benefits of technology

It achieves a stable supply of nitrogen for extended periods, improves automation, reduces operational risks, and enhances the reliability and practicality of the gas supply system.
