What are the maintenance precautions for an oil interfacial tension tester?

2025-05-08

The maintenance of an oil interfacial tension tester should pay attention to the following matters:

1. Cleaning and Inspection

Regular Cleaning of the Instrument: The measuring parts and sensors should be kept clean to prevent the attachment of oil or moisture, which can affect measurement accuracy. The surface of the sensors can be cleaned with a dedicated cleaning agent or a non-fiber cloth. Avoid using corrosive or abrasive cleaning agents during cleaning.

Inspection of Electrical Connections: Check the power supply and data transmission lines to ensure stable connections and prevent signal interruption.

Inspection of Connection Components: The instrument consists of multiple components, including sensors, displays, and connecting wires. Regularly check these components for looseness or damage to ensure all connections are secure and reliable.

2.Calibration and Maintenance

Regular Sensor Calibration: Calibrate the sensors using standard interfacial tension solutions. Adjust the instrument settings to ensure that the measurement error is within the specified range. It is generally recommended to calibrate the instrument once every three months. When working in high-temperature environments, the frequency of calibration should be increased.

Temperature Control System Maintenance: The determination of the interfacial tension of transformer oil needs to be carried out under specific temperature conditions. The stability of the temperature control system is crucial. Regularly check the working status of the temperature control equipment to ensure that the temperature is within the set range.

Replacement of Consumables: Some instruments may use consumables, such as sensor protective films or filters. These consumables should be replaced regularly according to usage conditions to ensure the normal operation of the instrument and the accuracy of measurements.

3. Usage and Storage

Control of Usage Environment: The performance of the instrument may be affected by environmental factors such as temperature, humidity, and vibration. The instrument should be placed in a stable, dry, and temperature-appropriate environment, avoiding places with extreme temperatures and humidity.

Proper Storage of the Instrument: When storing the instrument, place it in a dry, ventilated, and non-corrosive gas environment, avoiding direct sunlight and humidity.

Transportation Protection: When transporting the instrument, place it in anti-vibration, moisture-proof, and corrosion-resistant packaging to prevent damage.

4. Other Precautions

Safe Operation: When performing maintenance and repair, ensure that the instrument is powered off and the power plug is removed. Avoid using wet cloths or chemical solvents to prevent damage to the instrument’s surface.

Record Keeping of Maintenance: When performing maintenance and repair, record the time, location, content, and results of the maintenance for future reference.
