Super detailed! Regular maintenance methods for carbon fiber high-temperature creep testing machine are publicly available

The carbon fiber high-temperature creep testing machine is a precision equipment specifically designed to test the creep performance of carbon fiber and its composite materials in high-temperature environments. It is widely used in aviation, composite material research and development, and materials science fields. Due to the long-term operation of equipment under high temperature and stress conditions, regular maintenance is crucial for ensuring testing accuracy and extending equipment life. The following is a specific introduction to the regular maintenance methods of the carbon fiber high-temperature creep testing machine.

1. Heating system inspection and calibration: Use calibrated standard thermocouples every quarter to verify the temperature at multiple points inside the furnace, ensuring that the temperature control accuracy is within the specified range; Within 2 ℃; Check whether the heating element (such as silicon molybdenum rod, resistance wire) is broken, aged or locally overheated, and replace it if necessary.

2. Lubrication and cleaning of loading mechanism: Clean mechanical transmission components such as levers, screws, and guide rails monthly, and add high-temperature resistant grease (such as molybdenum disulfide based) to prevent sticking caused by high-temperature oxidation; Check whether the weight or servo loading system is stable and free of jumping.

3. Maintenance of displacement measurement system: Regularly calibrate the zero point and linearity of LVDT or grating displacement sensors with standard measuring blocks; Remove dust or oxides from the sensor probe and guide rod to avoid signal drift affecting the accuracy of the creep curve.

4. Furnace body and insulation layer inspection: Check the high-temperature furnace lining, insulation cotton, and sealing ring for damage, detachment, or sintering hardening every six months; If furnace deformation or decreased insulation performance is found (such as significantly prolonged heating time), timely repair or replacement of insulation materials should be carried out.

5. Cooling and exhaust system cleaning: After the test, the furnace body needs to be cooled by air or water cooling. The cooling fan filter and cooling water circuit should be regularly cleaned to prevent blockage; Check if the exhaust pipe is unobstructed to prevent volatile decomposition products from corroding internal components.

6. Electrical and safety protection function testing: Verify the effectiveness of safety interlocks such as over temperature protection, power-off self-locking, and emergency stop button on a monthly basis; Check whether the cable joints are loose or the insulation is aging, especially paying attention to the heat resistance of the leads in high temperature areas.

7. Software and data backup management: Regularly update control software, verify time load temperature synchronization logic; All historical experimental data should be archived and backed up according to the project to prevent data loss caused by hard disk failures.
