PCCP wire breakage detector pipeline leakage monitoring system series

1、 Product Description

PCCP wire breakage detector pipeline leakage monitoring system seriesFS-5500 is mainly used on Prestressed Concrete Cylinder Pipe (PCCP) for judgingPCCP tube windingThe use of distributed fiber optic sensing technology to detect broken steel wires and pipeline leaks in PCCP enables real-time online measurement, providing a reliable technical means for online health monitoring of the entire lifecycle of PCCP pipelines. Why use itPCCP wire breakage detector pipeline leakage monitoring systemSeries products? The main reason is that PCCP pipelines are deeply buried underground, with large spatial dimensions and long spans, making it difficult to visually observe their broken wires or obtain their location. Excavating pipelines to detect broken wires will affect the operation of water pipelines. Therefore, non-destructive testing is very important. Traditionally, point based sensing structures have been widely used and are susceptible to electromagnetic interference. However, distributed fiber optic sensing technology can achieve real-time monitoring of any position on the sensing fiber, with advantages such as small size, low cost, fast response speed, strong resistance to radiation and electromagnetic interference, and is highly suitable for structural health monitoring of large-scale infrastructure.

4、 Functional Features

1canReal time recording of the number of broken threads in each section of the pipeline, determining the remaining bearing capacity of the pipeline, and then issuing a pipe burst warning based on the pressure/strain monitoring results inside the pipeline.

2. The system monitors high-frequency acoustic signals based on Michelson interference principle, identifies broken wire signals, synchronously monitors low-frequency signals based on backward Rayleigh scattering principle, and locates broken wire signals.

3. Based on the results of wire breakage monitoring, the nonlinear finite element analysis method is used to calculate the remaining bearing capacity and deformation of the pipeline structure, and then a pipe burst warning is made according to the pressure/strain monitoring results inside the pipeline.

4. Intrinsically safe and reliable,Wire breakage detectorThe optical fiber used does not generate electrical sparks, and the power transmitted through the fiber is strictly controlled to avoid any danger.

5. Can be used in dangerous and harsh environments. All fiber optic products undergo strict quality monitoring and simulated environmental testing before leaving the factory to confirm their suitability for various harsh environments.

6. Can achieve simultaneous monitoring of multiple points and events without affecting each other; High sensitivity and rapid response: The fiber optic acoustic vibration monitoring system responds quickly to the measured area with a low false alarm rate.‍
