Pipeline leak detector is a widely used equipment for pipeline inspection and maintenance, it can quickly and accurately locate the leakage of pipeline through both acoustic wave and gas detection, and also can accurately locate the position and direction of underground pipeline. In this paper, we will introduce the working principle of the pipeline leak detector, equipment composition, use of process, application scenarios and precautions.


First, the basic composition and function of pipeline leakage tester

Pipeline leak detector is mainly composed of host, probe, headset and so on. The host is responsible for signal processing and display, the probe is responsible for collecting signals, and the headset is used for receiving sound signals. Among them, the acoustic detection probe can collect the sound of pipeline leakage, the gas detection probe can analyze the gas content of the pipeline leakage, and the sound device can produce a specific acoustic signal to locate the pipeline in the case of unknown pipeline direction.

Second, the use of pipeline leak detector process

When using the pipeline leak detector for testing, you need to follow the steps below:

1. Select the appropriate probe and install it on the host;

2. Select the appropriate test mode, such as acoustic wave or gas detection;

3. Place the probe on the pipe interface or water leakage;

4. Turn on the host, start testing;

5. Observe the signal column and value changes displayed on the interface of the host computer;

6. Listen to the sound of pipe leakage through the earphone;

7. Analyze and judge according to the test results.

Pipe Leak Detector Test Methods


1. Acoustic wave detection method: place the acoustic wave probe in the pipe interface or water leakage, turn on the host, the probe will collect the sound of pipe leakage. By observing the change of signal column and value in the interface of the host, the location of the leakage point can be judged.

2. Gas detection method: Inject hydrogen and nitrogen gas mixture into the pipeline, and use the special hydrogen probe to collect and analyze the leaking hydrogen. The hydrogen content of the leak is detected in real time and displayed on the interface of the host in the form of signal column and numerical value. By observing the changes of signal column and value, it can locate the leakage of pipeline.

Application Scenarios of Pipeline Leak Detector

1. Water Supply Pipeline: Leakage of water supply pipeline will not only seriously affect the water supply efficiency, but also waste a lot of water resources. Pipeline leak detector can help quickly and accurately detect the leakage location, carry out timely maintenance to ensure the stability and reliability of water supply.

2. Firefighting pipeline: Leakage of firefighting pipeline will lead to water leakage and cause serious pollution to the environment. The use of pipeline leakage detector can quickly locate the leakage point, timely repair and reduce environmental pollution.

3. Industrial pipeline: in industrial production, pipeline leakage will not only affect production efficiency, but also may cause safety accidents. Pipeline leak detector can detect the leakage location without stopping production, to protect production safety and production efficiency.

V. Precautions for using pipeline leakage tester

1. Before use, you need to check whether the functions of the equipment are normal, especially whether the probe is intact, to avoid affecting the test results.

2. In the testing process, you need to maintain the stability and reliability of the equipment, avoid unnecessary movement and shaking, so as not to affect the test results.

3. In the testing process, you need to pay attention to the impact of environmental factors, such as wind, rain, etc., so as to avoid misjudging the sound of water leakage.

4. When using the gas detection method, you need to pay attention to safety issues, to avoid excessive hydrogen concentration caused by safety hazards.

5. After the completion of the test, you need to record the test results in time, and organize and analyze them in order to better maintain and manage the pipeline.

In conclusion, pipeline leakage tester is a very practical device that can help us quickly and accurately detect the leakage location of pipelines and precisely locate the position and direction of underground pipelines. It has a wide range of application prospects in the fields of water supply, drainage and industrial production. Understand its working principle, equipment composition, use of processes and application scenarios, and pay attention to the safety issues in use
