Description

Technical Field

[0001] The present invention relates to the technical field of misalignment adjustment devices, and more specifically to a misalignment adjustment device between pressure pipes of a pumped storage power station. Background Art

[0002] The misalignment adjustment device for pressure pipelines in pumped storage power stations refers to the misalignment of pipeline joints caused by various reasons during pipeline installation, which needs to be adjusted through specific devices and methods to ensure the normal operation and safe use of pipelines. If the misalignment problem is not corrected, it may cause welding defects, increase stress concentration, and even cause leakage and accidents. The misalignment adjustment device and technology for pressure pipelines are key links in ensuring the quality of pipeline projects. Through specially designed devices and standardized operating procedures, the amount of pipeline misalignment can be effectively controlled and adjusted, thereby improving the quality of pipeline welding and ensuring the safe and stable operation of the pipeline system.

[0003] In daily use, the existing misalignment adjustment device between pressure pipelines of pumped-storage power stations is used to adjust the pressure pipelines of pumped-storage power stations due to misalignment. Because the pressure pipelines are seriously misaligned and the distance between the pressure pipelines is far, resulting in a long connection distance, the fixing distance of the existing pipeline adjustment device is insufficient, resulting in the pressure pipelines being not fixed stably due to insufficient distance, thereby reducing the stability of the pipeline docking, thereby affecting the operator's experience.

[0004] The existing misalignment adjustment device between the pressure pipelines of the pumped storage power station can only fix the pipeline by squeezing the arc ring outside the pipeline during daily use, so as to make misalignment adjustment. During the docking process, the misalignment tolerance of the pipeline cannot exceed 10% of the wall thickness and is not greater than 2mm. Because the thickness of the pipeline is different during the production process of the pipeline, when making external adjustments, the height inside the pipeline is different, which affects the accuracy of the operator's use of the adjustment device.
