The maintenance of the friction coefficient tester should follow systematic standards to ensure the long-term stability and testing accuracy of the equipment. The specific method is as follows:
1. Cleaning and dust protection
Daily cleaning: After each use, wipe the body with a soft cloth to remove dust, oil stains, and sample residues. Focus on cleaning sensors, friction tables, and clamping devices to avoid impurities interfering with testing accuracy.
Dust and Sun Protection: During non use periods, it is necessary to cover it with a dust cover and store it in a dry, ventilated, acid and alkali free environment, avoiding direct sunlight and moisture.
Precision component protection: It is strictly prohibited to touch the force sensor (extra care should be taken when replacing the sample) to prevent data distortion caused by impact.
2. Lubrication and rust prevention treatment
Lubrication of mechanical components: Regularly inject an appropriate amount of lubricating oil (according to the specified model in the equipment manual) into moving parts such as guide rails, gears, and lifting screws to reduce friction losses, and lubricate at least once every quarter.
Metal rust prevention: Metal parts that have not been sprayed with paint should be coated with rust proof oil after cleaning, and maintenance frequency should be increased during the rainy season.
3. Calibration and precision maintenance
Regular calibration: Use standard test blocks every quarter to verify equipment accuracy, with a focus on checking sliding length, pressure parameters, and sensor readings to ensure compliance with international standards.
Software update: Timely upgrade control software and optimize data collection and processing functions.
4. Management of vulnerable parts
Friction plate/worn wheel replacement: Replace in a timely manner based on the warning indicator light (such as a red light) or regular inspection results to avoid testing deviation caused by excessive wear. When disassembling, turn off the power and use specialized tools for operation.
Spare parts storage: Spare parts should be stored in a dry parts box and coated with rust proof oil to prevent oxidation.
5. Electrical system maintenance
Circuit protection: Regularly check for aging and poor contact of wires to ensure that the electrical control box is free of oil and dust intrusion; When idle for a long time, it is necessary to turn on the power every month to drive the tide.
Battery management: If the device contains batteries, they need to be removed after long-term use, and it is prohibited to mix old and new batteries when replacing them.
6. Storage and transportation regulations
Storage requirements: After disassembling the components and returning them to their original packaging box, avoid deformation caused by compression.
Transportation protection: Long distance handling must be secured with shock resistant boxes to prevent damage to the pendulum or sensor from impact.
7. Professional maintenance suggestions
Complex faults require contacting the manufacturer for repair; Establish maintenance records to record the time, content, and calibration results of each maintenance.
Core principle: Daily protection is the main priority, with regular maintenance as a supplement. Through preventive maintenance, equipment life is extended and data reliability is guaranteed.
