In our daily life, water supply pipeline carries the important mission of guaranteeing water for residents. However, with the aging and damage of pipelines, water leakage has gradually become a problem that cannot be ignored. In order to protect the lifeline of the city and ensure the stable operation of the water supply system, accurate water leakage detection technology has emerged. In this article, we will take you to explore the mystery of underground water supply pipe leakage detection, and understand how to realize the precise positioning and rapid repair of water leakage points through advanced leakage detection equipment and technology.
1, water leakage detection: the art of sound detection
Sound detection, as a unique means of water leakage detection, the principle lies in capturing the "leakage noise" generated when water flows out of the pipeline pores. The frequency of these noises is affected by a number of factors, including water pressure, the size and shape of the leak, the pipe material, and the landfill material. Although the loudest point is often the most likely to be the leak, complex noise environments such as wind, traffic noise, high flow water and pump operation can interfere with detection. Therefore, sound detection is usually carried out at night in the quiet to ensure that the clearest and most accurate leak sound.
2、 Leak detection equipment
At present, most of the commonly used leak detection equipment is using acoustic principle work, although the use of other principles of leak detection equipment in the continuous emergence of the use of our country is still relatively small. Usually for better leak detection work, there is a need to configure such as pipeline meter and other auxiliary equipment.
Listening stick
Listening stick is the most primitive leak detection equipment, by the rod body and earpiece composition. The price of the listening stick is low, easy to use, and it can still play a big role in the leak detection work.
pipeline leak detector is the technical extension of the listening stick, generally referred to as leak detector, pipeline leak detector consists of probe, host, headset.
PQWT-L7000 pipeline leak detector through the sensor will leak the sound signal acquisition, after the acquisition of the signal through the host processing, to visualize the spectrum and the way the signal column is displayed on the host screen, while the sound will also be output through the host to the headset, through the "listening", Through the combination of "listening" and "seeing", the leakage point is analyzed and judged.
"Census mode" + "positioning mode" double lock leakage point, can be accurate, fast and effective solution to all kinds of home pipeline leakage problems.
Pipeline locator
PQWT-GX800 Pipe Cable Locator is a set of high-performance underground metal pipeline detection system, composed of signal transmitter and receiver, which can be used for path detection of metal pipelines and underground cables, pipeline census and depth measurement, as well as pipeline insulation breakage and part of the type of cable fault finding.
PQWT-GX700 Pipe Cable Locator is designed based on the electromagnetic induction method and the application of communication principle. In the use of more humanized design, through the large screen LCD display signal strength, bar grid, arrows and sound prompts make it easy for the operator to determine the underground location of the underground metal pipeline towards the direction, as well as the depth.
Each type of equipment has its own applicable working conditions, there is no one equipment can solve all the problems. Simple equipment and tools, as long as they are properly applied, can also play a great role. Therefore, in the leak detection work, we need to according to the site conditions and the ability of the equipment, the flexible use of a variety of equipment and means to complete the task of leak detection.
Leak detection of underground water supply pipes is a job that requires a combination of technology and wisdom. Through accurate leakage detection technology and advanced leakage detection equipment, we can quickly and effectively solve all kinds of household pipe leakage problems and ensure the normal operation of the water supply system.
