1. Regular calibration and functional verification
Sensor calibration
The sensor is calibrated monthly with standard gas to ensure that the detection accuracy error is ≤0.5%, and the calibration record is kept.
Key components such as ultrasonic thickness gauges and pressure sensors need to be calibrated by professional institutions every quarter to avoid data deviations.
Functional self-test and alarm test
The equipment self-test program is started every week to test the sensitivity of the alarm function and the stability of the data acquisition module.
Regularly verify the tightness of the hydrostatic testing machine and test the leak rate detection sensitivity through standard leak holes.
2. Cleaning and appearance maintenance
Equipment Cleaning Specifications
Use a soft cloth to wipe the equipment housing, display and operation panel daily, and avoid using alcohol or corrosive cleaning agents.
Vacuum barrels, spray guns and other parts that are prone to fouling need to be disassembled and cleaned every week to prevent residues from affecting the test results.
Critical parts are cleaned
Regularly clean the ultrasonic flaw detector probe and endoscope lens to ensure that there is no oil or scratch to interfere with the detection accuracy.
3. Power supply and battery management
Check whether the power cord and interface are aging, and replace the damaged circuit in time to avoid the risk of short circuit.
Portable device batteries need to be charged regularly (once a month recommended) and stored separately when left unused for long periods of time23.
4. Consumables replacement and hardware inspection
Replacement of wearing parts
Consumables such as seals and sensors should be replaced every 2-3 years, and severely worn parts (such as robotic arm drive belts) should be stopped for maintenance immediately.
Check the connection status of the internal pipeline of the host every six months, and replace the aging or deformed pipeline.
Mechanical structure inspection
Lubricate and maintain the sliding parts such as guide rails and lead screws of the equipment every month, remove burrs and adjust the fitting clearance.
5. Data management and software updates
The test data needs to be uploaded to the management platform in real time to ensure that the historical record can be traced back to more than 10 years.
Regularly update equipment firmware and control software to optimize data algorithms and system compatibility.
6. Environmental control and storage
Requirements for the use environment
The detection area should be ventilated and dry, and the temperature should be controlled at 5-40°C to avoid strong magnetic fields or dust interfering with the operation of the equipment.
The combustible gas concentration needs to be <10% LEL, and the oxygen concentration monitor is equipped to ensure safe operation.
Long-term storage specifications
The deactivated equipment should be covered with dustproof film after power failure, and stored in an environment protected from light and no corrosive gas.
7. Safety protection and operation specifications
Wear anti-static clothing and pressure-resistant gloves during maintenance to prevent accidents caused by high-voltage gas leakage or static electricity.
Regularly check the function of the emergency pressure relief device and bypass valve to ensure that the air supply can be quickly cut off in the event of a sudden failure.
8. Maintenance of records and professional services
Establish maintenance files to record calibration, consumables replacement and troubleshooting details, so as to facilitate traceability of equipment status.
Every year, a professional organization is commissioned to conduct a comprehensive inspection of the equipment, focusing on the evaluation of mechanical stability and electrical safety
