The debugging of laboratory high-pressure reactors is the core link to ensure the safe operation of equipment and the accuracy of experimental data. Based on device operation specifications and safety management requirements, the following are standardized debugging processes and key technical points:

1、 Preparation stage before debugging

-Hardware inspection

-Confirm that there is no physical damage to the reactor body, stirring system, heating device, and connecting pipelines.

-Verify the accuracy of pressure gauges, temperature sensors, safety valves, and other instruments, with intact lead seals and clear red line markings.

-System cleaning and sealing pre inspection

-Remove residue from the kettle, rinse with solvent and dry; Check if the sealing ring is aging or deformed.

-Manually rotate the mixing shaft to ensure there is no jamming or abnormal noise.

2、 Core debugging process

-Air tightness pressure test

-Nitrogen replacement and pressure maintenance: Close all valves (except for exhaust valves), fill nitrogen to 1MPa, and then close the intake valve. Observe the pressure changes and confirm if the device is leaking air.

-Segmented leak detection: Apply soapy water to the flange and valve joints, and if no bubbles are generated after ventilation, it is considered qualified.

-Functional verification

-Control system joint debugging: Input temperature and pressure threshold parameters to verify the response speed of automatic alarm and power-off protection functions.

3、 Optimization of operating parameters

-Dynamic control parameter matching

-Set a gradient heating program based on the reaction type, synchronously monitor the deviation between the actual temperature and the set value, and adjust the PID parameters to suppress overshoot.

-The hydrogen pressurization rate should be controlled within 0.1MPa/min to avoid safety hazards caused by sudden pressure changes.

-Emergency response testing

-Simulate overpressure scenarios (exceeding the design pressure by 10%) to verify whether the safety valve's tripping pressure and release efficiency meet the standards.

-Conduct leakage and overload protection tests to ensure that the emergency shutdown system can cut off power within 0.5 seconds.

4、 Trial operation and delivery

-72 hour continuous load test

-Record the stability curves of each parameter, with pressure fluctuations of ≤± 0.02MPa and temperature errors of ≤± 1 ℃.

-File archiving and training

-Prepare the Equipment Calibration Report and Operational Risk Plan, and conduct practical assessments for experimental personnel.
