With the acceleration of urbanization, the number of various pipelines is increasing. However, due to aging, corrosion, wear and tear, pipes may have water leakage problems. In order to find and solve these problems in time, we need to adopt some effective water leakage detection methods. The following will introduce five commonly used water leakage detection methods.
1. Water leakage detector sound detection method
Water leakage detector sound detection method is a way to pick up the water supply pipe leakage sound, to determine the location of the leakage method. This detection method is widely used in all types of pipeline leakage census, can be carried out in the environment with less noise. The use of audio detection method, you need to use professional equipment, easy to operate and is not subject to the pipe diameter, material, detection time limitations. Through this method can be pre-located leakage location, for subsequent maintenance to provide an important basis.
2. Water leakage detector correlation meter detection method
Water leakage detector correlation meter detection method is an advanced leakage detection method, especially suitable for environmental interference noise, pipeline buried too deep or unsuitable for ground listening method of the region. The method quickly and accurately measures the precise location of underground pipe leaks by means of a correlator. The correlator can provide high-precision pipeline leakage detection operations, effectively improving the accuracy and efficiency of water leakage detection.
3. Water leakage detector CCTV pipeline endoscopic detection method
Water leakage detector CCTV pipeline endoscopic detection method is a method of pipeline detection through CCTV pipeline endoscopic robot. The method is applicable to a variety of leakage pipe detection, you can clearly see the image data of the inner wall of the pipe. For large diameter pipes such as PE, PVC, ceramic, cement and other pipes that are buried deep and difficult to inspect, the CCTV Pipe Snooping Inspection Method can provide an effective inspection solution. The method can accurately find out the leakage and breakage points inside the pipeline and provide precise positioning for maintenance.
4. Water leakage detector tracer gas detection method
Water Leakage Detector Tracer Gas Detection Method is a method of finding abnormalities and confirming leaking pipe segments by delivering gas to the sealed pipe and then conducting an inflation test. During the test, a hydrogen-nitrogen mixture (5% hydrogen and 96% nitrogen) is injected into the pipeline, and after a certain pressure is reached, the pipeline is pumped and tested using a hydrogen gas detector. If anomalies are found and leaks are recorded around them, further testing work is carried out to find out the exact location of the leaks. This method is applicable to a variety of pipeline testing, with safe, non-toxic, non-flammable features, the instrument is simple to operate, can be a water pipe, gas pipeline tiny leaks to locate the point.
5. Water leakage detector far infrared thermal imaging detection method
Water leakage detector far-infrared thermal imaging detection method is a use of photoelectric technology to detect the object thermal radiation of infrared radiation of a specific band signal method. The method converts the signal into images and graphics that can be resolved by human vision, and further calculates the temperature value. The use of far-infrared thermal imaging cameras can detect information related to corrosion, rupture, thinning, clogging, and leakage of product transmission and piping, refractory and insulation materials, and a variety of reactors, and can quickly and accurately obtain two-dimensional temperature distributions on the surfaces of equipment and materials. This method is applicable to a variety of large-scale equipment for the detection of safety hazards, can be found as early as possible equipment safety hazards, for the use of equipment to provide a scientific evaluation of the condition, in order to ensure the safe operation of the equipment.
In summary, the above five water leakage detection methods have their own characteristics, we can choose the appropriate method for water leakage detection according to the actual situation. Timely detection and resolution of water leakage problems help to protect our quality of life and safety.
