Research on pipeline leakage location based on negative pressure wave method

As an important part of the warship, the safety of the pipeline system is of great significance to the vitality of the warship. In practical engineering, due to the harsh working environment and inconvenient maintenance of the warship's pipeline system, the problem of damage and leakage often occurs. Aiming at the problem that it is difficult to detect and locate the leakage of warship pipelines in real-time, based on the negative pressure wave positioning theory, a pipeline leakage positioning scheme is designed, and the semi-physical simulation method is used to build a test platform to carry out experimental research. The research results show that the designed pipeline leakage location detection platform program is executed correctly, and can quickly and effectively locate the leakage position of straight pipelines.
