The underground water leak detector must have an auxiliary tool to perform its function. The auxiliary tool of the underground water leak detector mainly includes the puncher's leaking rod, and the leak detector can work normally. The following is the auxiliary of the underground water leak detector. The tool is described in detail.

First, the puncher

When it is not clear the specific location of the leaking pipe, determine whether the area is leaking water. The tool puncher is used. Above the suspected water leaking position, use a puncher to vertically punch a 1.5-meter hole. See if there is a clear water.

Second, the leak bar

The leaking bar is commonly called the leaking rod, the listening stick, the listening stick, the listening needle, the listening stick, etc., its shape is like a probe, and the tail is equipped with a metal rod that can be closely attached to the ear, and the conduction principle can be used. Accurately judging the problem area, through the contact of the sound bar on the surface of the device being inspected, it is possible to collect various faint sounds of various types of equipment that are inaudible due to air isolation and external interference. Just like a doctor's stethoscope, the contact sound of the human body can be used to hear the beating sound of the heart, the gastrointestinal peristalsis, and the breathing sound.

As a kind of ideal inspection tool, the application of leaking rods, urban water network pipelines, valve leakage, air leakage, inspection machines, equipment failure, coal mine permeable sound, petroleum, chemical, power generation, metallurgy, mining, coal mine, machinery And other industries.

The operation method of the leaking rod can be said to be extremely simple, but it can be accurately judged by the problem, but it is the accumulation of time experience: for example, the urban water network pipeline leak detection method is to put the tip end of the leaking rod in the pipeline. In the exposed place, the earpiece is attached to the ear and carefully listened. It can be discerned whether the pipe near the measuring point is leaking. If there is a "beep", the water pipe may leak. The general experience is: if the hole is small, It is the voice of "Si Si", if it is big, it will "boom". Experienced technicians can even determine the extent of the leak point within the range of the frequency of the leaking sound.

The underground water leak detector is generally used in conjunction with a water leak detector, which is used to accurately locate the location of the leak.

Third, the pipeline underground water leak detector

Leakage detectors, underground water leak detectors, or pressure pipe leak detectors are mainly used for leak detection. The principle is that “the flow of water in the pipeline from the leak point under the action of pressure is transmitted along the pipeline along the noise generated by the impact inner wall, or propagates along the buried medium to the ground, and the leakage point is determined by the sensor amplifying the leakage noise”. The sensor of the test instrument is used to detect above the pipeline surface to achieve the purpose of finding the leak point.
