1. Working principle
The cold regions in the north have large seasonal temperature differences and deep permafrost layers. To prevent the sedimentation well and drainage pipe from freezing in winter and ensure the effectiveness of the automatic oil interception and drainage system in the tank area, the drainage pipe of the automatic oil interception and drainage system is buried parallel below the frozen soil layer during installation. This ensures that the automatic oil interception and drainage system is not affected by seasonal temperature differences and can automatically discharge water, intercept oil, and shut down when there is no water.
