In pipe network management, effective leakage control is the key to ensure the effective utilization of water resources. The establishment of leakage pick-up area for leakage control is an effective method, but need to be combined with the basic situation of the pipe network and technical force, reasonable choice of leakage pick-up method for active leakage control.
Leakage control technology
1. Area leakage detection method
Area leakage detection method is a commonly used method of leakage detection, applicable to neighborhoods and other areas. Through monitoring and testing, leakage points can be found in time and measures can be taken to repair them, so as to reduce the waste of water resources.
2. Area sound leakage detection method
Monitor the sound, vibration or fluctuation produced by water flow, and determine the location of leakage by analyzing these signals, quickly narrowing down the scope of leakage and improving the accuracy of positioning.
Leak detection technology
1 . Listening sound pole
Determine the location of the leakage point by listening to the sound of underground water pipe leakage. For shallow leaks, this method is more effective.
2 . pipeline leak detector
A pipeline leak detector is a device designed to detect the location of leaks in a pipeline system. It accurately detects leaks by means of electronic sensors and signal processing systems.
3. correlator
Utilizes the principle of sound propagation to locate the leakage point with high positioning accuracy.
4 . Bottom-detecting radar
Scans the underground of the piping system by sending electromagnetic waves and measuring the reflected signals to locate potential leakage points.
Pipeline Location Techniques
1 . Metallic pipeline localization
Locate buried metal pipelines by detecting the electromagnetic signals emitted from them to accurately avoid pipeline damage.
2. Non-metallic pipeline localization
For non-metallic pipelines, the use of ground-penetrating radar and other equipment to locate, which helps construction and maintenance.
3 . Neural network technology
Combined with artificial intelligence technology, it processes and analyzes a large amount of underground pipeline data to improve positioning accuracy and reduce blindness.
The application of pipe network leakage detection technology is an important means to improve the efficiency of water resources utilization. Through the reasonable selection of applicable technologies and methods, timely detection and repair of leakage points can effectively reduce the waste of water resources and ensure the sustainable use of water resources.
