Sound detection
The principle of sounding is that different frequencies of “leakage noise†occur when water flows out of the pores of the pipeline. The frequency is determined by the water pressure, the size and shape of the leak, the material of the pipeline and the landfill data. Indirect sounding using a ground microphone can be used to detect low frequency leakage noise through the ground. But because this is also the frequency segment of footsteps and traffic noise, an experienced leak detector is required to obtain satisfactory results. When detecting the noise of the leak, the leak may be located at the point where the sound is the loudest, but too much noise will increase the difficulty of direct and indirect sound exploration. Wind noise, traffic noise, large flow and pump will cause the detection work to arise. Sounding is most effective at night.
Second, the leak detection equipment
Currently widely used leak detection equipment is an underground pipeline leak detector, also known as a water leak detector or leak detector, etc.
The leak detector is the original leak detection device consisting of a rod and an earpiece. The leaky bar is low in price and convenient to use, and it still plays a big role in leak detection.
2) Water leak detector
The leak detector is an extension of the technique of leaking the rod, the leak detector, abbreviated as a leak detector, and the leak detector is formed by the probe, the host, and the earphone.
The leak detection method of the leak detector is consistent with the basis of the leak detector. Check the fittings of the pipeline in the tested area to see if there is any water leakage sound. Initially determine which section of the pipeline is leaking, and then listen to it one or two steps along the ground on the pipeline. Be careful to move slowly near the leaking point. Until the leak point can be determined.
3) Correlation meter
When the water leaks, it will send noise to the four sides. The leaking rod and the leak detector are the sound of leaking water on the ground of the pipeline to be tested. Because the acoustic properties of the medium are different, it is often difficult to confirm the position of the leak. The strong annoyance of noise makes these instruments inoperable. The correlation meter determines the leak point based on the time difference of the leaking sound transmitted along the pipeline flow to the split probe.
Comprehensive use of leak detection equipment and means
The application of each type of equipment must be satisfied with certain working conditions, otherwise the consequences of the work may not be ideal or even deformed, and there is no progressive equipment that may solve all problems. Simple equipment tools can also play a big role if used properly. Therefore, in the implementation of the leak detection work, according to the site situation and existing equipment capabilities, application and invention premise, the mobile use of a variety of equipment and wrists to achieve the leakage test obligations.
