Description

Technical Field

[0001] The present invention belongs to the technical field of nuclear power vibration reduction, and in particular relates to a vibration reduction system based on multi-device linkage. Background Art

[0002] In existing technology, nuclear power plant generator sets are high-power and have numerous auxiliary systems. This results in numerous and complex pipelines interfacing with the generator sets, making it inconvenient to replace these pipelines during maintenance and affecting the normal operation of the generator sets. In this situation, when the generator set pipelines are affected by the generator set's own power frequency vibration, the unreasonable structural design of some of the generator set pipelines can easily cause a sharp increase in pipeline vibration, which can lead to pipe cracks and joint leaks in severe cases.

[0003] For example, the prior art CN106678481B discloses a method and device for treating systems related to nuclear power plant generator sets. For example, in the case of hydrogen cooling pipelines, long-term vibration exceeding the standard may cause hydrogen leakage at pipe joints or welds. Historically, cracks have been found at the pipe joint welds of hydrogen cooling pipelines, resulting in hydrogen leakage accidents. Hydrogen leakage may also lead to industrial safety risks such as hydrogen explosions. In addition, in the case of stator cooling water flow sampling and monitoring pipelines, which include stator cooling water flow inlet sampling pipelines and stator cooling water flow outlet sampling pipelines, these stator cooling water-related pipelines are prone to leakage at branch pipe welds or joints when long-term vibration exceeds the standard, affecting the accurate monitoring of flow and affecting the oxygen content of the generator stator cooling water. In addition, in the case of generator oil drain pipelines, long-term vibration exceeding the standard is prone to oil leakage accidents at pipe joints or welds, which not only affects the normal operation of the generator set but also may bring industrial safety risks such as explosions.

[0004] Existing technologies such as KR101654364B1, EP2482996B1, and US08721396B1 involve water flowing both inside and outside the heat transfer tubes. This vibration can cause irreversible damage to the tubes, such as fretting and stress corrosion. Therefore, existing technologies incorporate anti-vibration strips on the heat transfer tubes to reduce vibration. However, existing anti-vibration strips only support the curved sections of the heat transfer tubes and employ rigid support for stability. Rigid support components are more susceptible to water flow impact, resulting in limited vibration reduction effectiveness and a limited service life. Summary of the Invention
