Leakage of underground water pipes has always been a problem in city management and residents' lives. Leakage is not only a waste of water resources, but also may cause damage to the foundation of the building, and even lead to ground subsidence and other safety hazards. In order to timely and accurately detect and repair the leakage problem, modern technology has introduced a variety of underground water pipe leakage detector, these instruments through advanced technology, can quickly locate the leakage point, to provide strong support for the repair work.
First, sound leakage detector
Sound leakage detector is a passive monitoring equipment, it uses the water pipe internal leakage generated by the specific sound frequency detection. These sound frequencies are analyzed and identified by the instrument to determine the location of the leak. The instrument is non-invasive and can be used to monitor without affecting the normal water supply, greatly improving monitoring efficiency. To use, simply place the sensor near the underground pipe, carefully listen to and analyze the sound of water flow near the pipe, and then you can make a preliminary judgment of water leakage.
Second, groundwater dynamic monitor
Groundwater dynamic monitor is a more advanced instrument, it is installed in the pipeline through the sensor inside the real-time monitoring of the pipeline pressure, flow and temperature and other parameters. Once there is a water leakage, these parameters will change and the monitor will immediately capture these changes and issue an alarm. At the same time, through data analysis, it can also assess the extent and location of the leakage, providing precise information for emergency personnel. This kind of instrument can not only detect the water leakage problem in time, but also provide data support for the subsequent repair work.
Third, infrared thermal imager
Infrared thermal imager is a kind of instrument that uses infrared rays to detect the surface temperature of objects. In underground water pipe leakage detection, it can detect the temperature change of the soil around the pipe. When water leaks from a pipe, it takes away heat, causing the temperature of the surrounding soil to drop. An infrared thermal imager captures these temperature changes and displays them in an image, which helps inspectors pinpoint the leak. This instrument is characterized by intuitive, fast, is a powerful assistant in water leakage detection.
Fourth, the acoustic water leakage detector
Acoustic water leakage detector is a use of acoustic signals to detect underground water pipe leakage equipment. It is placed in the underground pipe near the sensor to capture the sound signal generated by the leak, and then analyze these signals to determine the location of the leak. With the advantages of simple operation and high portability, the acoustic leakage detector is widely used in underground water pipe leakage detection. It can accurately capture the sound of water leakage in a complex environment and provide reliable location information for maintenance personnel.
V. Geological radar
Geo-radar is a kind of instrument that utilizes electromagnetic waves for detection and can scan the position and depth of underground pipes. It determines the position and shape of underground pipes by transmitting electromagnetic waves and receiving the signals reflected back, analyzing the amplitude and phase changes of the reflected signals. When an underground pipeline is damaged or leaking, geo-radar can help locate the abnormal area and thus the leakage point. This instrument has unique advantages in water leakage detection under complex geological conditions.
VI. Pressure Tester
Pressure tester is a traditional water leakage detection equipment, which records water meter readings by shutting off the water supply valve and then waiting for a period of time to check the meter readings again. If the meter reading changes without the use of a water source, it indicates that there is a leak in the underground water pipe. Although this method is simple and inexpensive, it requires a certain level of expertise to accurately determine the location of the leak. Therefore, it is usually used as an auxiliary means of other detection methods.
Seven, choose the appropriate underground water pipe leakage detector
In the choice of suitable underground water pipe leakage detector, need to consider the following aspects:
1. Detection accuracy: the detection accuracy of different instruments is different, and it is necessary to choose a suitable instrument according to the actual demand.
2. Convenience of operation: the instrument should be easy to operate and maintain, so as to get started quickly and reduce misoperation.
3. Scope of application: Different instruments are suitable for different environments and pipeline types, and need to be selected according to the actual situation.
4. Cost-effectiveness: under the premise of guaranteeing the detection effect, choose the instruments with reasonable cost to reduce the maintenance cost.
To summarize, underground water pipe leakage detector is an indispensable and important tool in modern city management and residents' life. By choosing suitable instruments and using them correctly, we can timely and accurately find the leakage problems and take measures to repair them, so as to guarantee the effective use of water resources and the safety and stability of buildings.
