Pipeline leak detector plays a crucial role in the detection and maintenance of water supply, drainage, gas and other pipeline systems. Proper daily maintenance is crucial to ensure stable performance, accurate detection, and extended service life. The following will provide a detailed introduction to the daily maintenance methods and related precautions for pipeline leak detectors.
1、 Daily maintenance methods
（1） Instrument appearance cleaning
1. After each use, gently wipe the casing of the pipeline leak detector with a clean, soft, and damp cloth to remove surface dust, dirt, and potential water stains and other impurities. Avoid using cleaning agents containing corrosive chemicals to prevent damage to the material of the instrument casing.
2. Be extra careful to clean the display screen, operation buttons, and other parts of the instrument. A small amount of specialized screen cleaner can be sprayed onto a soft cleaning cloth, and then gently wiped to ensure that the screen is clear, stain free, and the operation buttons are flexible and easy.
（2） Sensor maintenance
Sensors are one of the core components of pipeline leak detectors, and their sensitivity directly affects the detection results. Regularly check the surface of the sensor for foreign objects such as dirt, rust, etc. If slight impurities are found, they can be gently brushed away with a soft bristled brush; For stubborn dirt, soak a cotton ball in an appropriate amount of anhydrous alcohol and carefully wipe the surface of the sensor, but be careful not to let alcohol flow into the interior of the sensor.
2. Avoid severe collision or compression of the sensor. During carrying and use, the instrument should be placed in a safe and stable location to prevent damage or performance degradation of the sensor due to accidental dropping or collision.
（3） Battery maintenance
1. Use and charge the battery correctly according to the instructions in the instrument manual. If it is a rechargeable battery, it should be ensured that the battery is basically depleted before charging, but do not over discharge to avoid affecting the battery life. When charging, use a matching charger and charge at a suitable ambient temperature to avoid damage to the battery caused by high or low temperature environments.
2. Regularly check whether the connection parts of the battery are loose or corroded. If loose connections are found, they should be tightened in a timely manner; For areas with signs of corrosion, they can be cleaned with rust remover first, and then coated with an appropriate amount of protective grease to ensure good battery connection and stable power transmission.
3. If the pipeline leak detector is not used for a long time, it is recommended to perform a charge discharge cycle on the battery every once in a while (usually about half a month) to prevent the battery from self discharging and causing a decrease in capacity or failure.
（4） Connection line inspection
1. Check whether the connection lines between the instrument and external devices such as sensors, headphones, chargers, etc. are intact. Check if there is any damage or cracking on the outer skin of the circuit, and if there is any looseness or poor contact at the interface. If slight damage is found on the outer skin of the circuit, insulation tape can be used for wrapping and repair; For loose interfaces, they should be promptly plugged in and checked for secure connections.
2. Regularly clean the interface parts of the connecting lines, and gently wipe the surface of the metal interface with an eraser to remove the oxide layer and dirt, to ensure the stability and reliability of signal transmission.
（5） Storage environment management
The pipeline leak detector should be stored in a dry, well ventilated, and suitable temperature environment. Avoid storing in damp, dusty, or areas with strong magnetic or electric fields. A humid environment may cause damage to electronic components inside the instrument, while strong magnetic and electric fields may interfere with the normal operation of the instrument.
When storing, the instrument should be placed in a dedicated instrument box or storage box, and ensure that the instrument is securely fixed inside the box to avoid damage caused by shaking during transportation or storage. Meanwhile, an appropriate amount of desiccant can be placed inside the instrument box to absorb moisture and maintain a dry environment.
2、 Precautions
（1） Pre use inspection
Before using the pipeline leak detector, it is essential to conduct a comprehensive inspection of the instrument. In addition to checking the appearance, sensors, batteries, connection lines, and other aspects mentioned above, it is also necessary to check whether the various functions of the instrument are normal. The instrument can be turned on, and a simple self check operation can be performed according to the operating procedure to check whether the display screen is displaying normally and whether the instrument can receive and process signals normally.
2. Confirm whether the accessories used in the instrument (such as sensor probes, headphones, etc.) are complete and intact. If there are missing or damaged accessories, they should be promptly supplemented or replaced to avoid affecting the smooth progress of the testing work.
（2） Operating standards
1. Strictly follow the user manual of the pipeline leak detector for operation. Different models and brands of instruments may have differences in operating methods, so it is important to be familiar with the relevant operating procedures and precautions before use. For example, when setting detection parameters, reasonable settings should be made based on the actual pipeline situation and detection requirements to avoid inaccurate detection results or instrument failures caused by improper parameter settings.
During use, handle the instrument gently to avoid rough handling. Especially when moving instruments or adjusting sensor positions, attention should be paid to smooth movements to prevent damage to the instrument due to violent shaking or collision. At the same time, it is necessary to avoid exposing the instrument to harsh environmental conditions such as high temperature, high pressure, strong acidity and alkalinity during the testing process. If testing is required in special environments, it should be ensured that the instrument has corresponding protective measures and is used within its allowable working range.
（3） Waterproof and dustproof
Although pipeline leak detectors usually have certain waterproof and dustproof capabilities, attention should still be paid to taking waterproof and dustproof measures during use and storage. When using instruments in damp or dusty environments, it is important to minimize the exposure time of the instrument and promptly clean and dry it after use. For example, when conducting inspections on rainy days or when there are water stains around pipelines, waterproof covers or plastic bags can be used to provide simple protection for the instrument to prevent water from splashing into the interior of the instrument.
2. It is strictly prohibited to immerse the instrument in water or expose it to serious water immersion situations such as rain or water flushing. If the instrument accidentally gets water, it should be immediately stopped from use and sent to a professional maintenance personnel for repair and treatment. Do not disassemble or test it on your own to avoid more serious damage.
（4） Avoid interference
When using a pipeline leak detector, try to avoid electromagnetic interference in the surrounding environment as much as possible. Stay away from strong electromagnetic radiation sources such as large motors, transformers, and welding machines, as these interference sources may affect the signal reception and processing of the instrument, leading to deviations or errors in the detection results. If these interference sources cannot be avoided at the testing site, measures such as adjusting the position of the instrument or using shielded wires can be attempted to reduce the impact of electromagnetic interference.
2. At the same time, attention should also be paid to avoiding other acoustic interferences. During the testing process, efforts should be made to minimize the noise in the surrounding environment, such as traffic noise, construction noise, etc. You can choose to conduct the detection during relatively quiet periods or use auxiliary tools such as soundproof earplugs to hear the sound signals detected by the instrument more clearly and improve the accuracy of the detection.
By implementing comprehensive and meticulous daily maintenance methods and strictly following relevant precautions, the pipeline leak detector can be effectively ensured to be in good working condition, improving the efficiency and accuracy of detection work, and providing strong technical support for the safe operation of pipeline systems.
