Water, an indispensable element in life, carries the dual mission of nourishing life and promoting social development. However, with the rapid development of society, the contradiction between the supply and demand of water resources is becoming more and more prominent, which has become a major challenge for us. In order to cope with this challenge, in addition to ensuring the abundance of water resources, we need to ensure the smooth and healthy operation of water supply pipelines.
In the city and plant underground, pipelines are crisscrossed, as the city's “lifeline”, carrying the heavy responsibility of energy and material transmission, is the cornerstone of the survival and development of enterprises. However, due to the water supply pipeline buried in the ground for a long time, natural aging phenomenon is difficult to avoid, pipeline leakage problems occur from time to time. If you can not find and repair leaking pipes in time, will not only lead to the loss of valuable water resources in vain, but also may cause damage to the roads, construction facilities and installations near the leakage point, and in serious cases, may even lead to water pollution, major economic losses and adverse social impact. Therefore, the use of pqwt water detector for accurate detection to ensure the safety and stability of water supply pipelines and healthy operation, has far-reaching and important practical significance.
The working principle of pqwt water detector is mainly based on sound recognition technology. When water leakage occurs in the water supply pipeline, the sprayed water rubs against the leakage opening, as well as impacts with the surrounding medium, etc., which generates vibrations of different frequencies, and then produces the sound of water leakage. These sounds propagate to both sides of the pipe in a sinusoidal curve and cause the pipe to vibrate. At the same time, the rapid outflow of water will impact on the medium around the pipe, resulting in leakage sounds with special frequencies, which are propagated to the ground through the surrounding medium and the pipe.
The core function of the pqwt water detector is to pick up these water leakage sounds and convert them into electrical signals. After appropriate amplification and digital filtering, the instrument is able to analyze and determine the exact location of the water leak. The types of water leakage sound can usually be divided into three kinds: leakage mouth friction sound, head impact sound and media friction sound. Each of these sounds has its own specific frequency and propagation characteristics, providing the pqwt water detector with a wealth of information to enable it to more accurately locate water leaks.
The application of pqwt water detector not only improves the detection efficiency of water supply pipes, but also reduces the maintenance cost, providing a strong guarantee for the sustainable development of the city. With the continuous progress of technology, the performance of pqwt water detector will continue to improve, bringing more convenience and security for our lives.
