The key points for the daily maintenance of brinell hardness testers include the following aspects:
一、First, cleaning and protection
- Regularly wipe the outer casing of the hardness tester with a clean and soft cloth to remove dust and stains.
- For example, wipe the casing with a dry cloth after each use to prevent dust from entering the interior of the instrument.
- Ensure that the hardness tester is placed in a dry, clean, vibration-free, and non-corrosive gas environment.
- For instance, avoid placing it near chemical reagents or in places with high humidity.
Second, maintenance of measurement components
- Regularly check whether the indenter is worn, damaged, or rusted.
- If the indenter is worn, it should be replaced promptly to ensure the accuracy of measurements.
- For example, after long-term use, the indenter may show tiny wear marks, and then an inspection is necessary.
- Keep the measurement table clean and flat to prevent debris from affecting the measurement results.
- Regularly clean the debris and stains on the measurement table.
Third, maintenance of the transmission mechanism
- Check the lubrication of transmission components such as lead screws and guide rails, and add an appropriate amount of lubricating oil in a timely manner.
- For example, check the lubrication of the lead screw once every six months and add the appropriate lubricating oil.
- Ensure that the transmission components move flexibly without jamming or abnormal resistance.
- If the movement is not smooth, identify the cause and handle it promptly.
Fourth, inspection of the electrical system
- Regularly check whether the power cord is damaged or aged.
- 1.For example, check the power cord once a year to prevent safety hazards such as electric leakage.
- Confirm that the electrical connections of the instrument are firm and reliable without loosening.
Fifth, accuracy verification
- Use standard hardness blocks to verify the accuracy of the hardness tester according to the prescribed cycle.
- It is usually recommended to conduct the verification once every six months.
- During the verification process, if a significant deviation in the measurement result is found, adjustments or repairs should be made in a timely manner.
Sixth, data recording and management
- Record the usage situation each time, including the measured sample, measurement result, and usage time, etc. – This helps to track the usage of the instrument and identify potential problems.
- Keep the relevant verification and maintenance records properly for future reference and review.
