A device and method for testing the hydrophobic performance of the inner wall of a pipeline

Abstract

The application discloses a device and method for testing the hydrophobic performance of the inner wall of the pipeline. The equipment for testing the hydrophobic performance of the inner wall of the pipeline includes a horizontal base, a base support rod vertically fixed on the horizontal base, and an adjustment bracket provided at the upper end of the base support rod. 1. The total support beam arranged on the upper end of the adjustment bracket and the pipe clamp assembly installed on the total support beam, the total support beam and the adjustment bracket are fixedly connected to form an integrated structure; the pointer is fixed on the adjustment bracket, and the base rod is fixed An angle indicator for reading the rotation angle of the pointer is provided. The adjustment bracket can rotate vertically on the base pole, and the pointer follows the adjustment bracket to rotate at a certain angle. The angle of pointer rotation can be read by the angle indicator. The device of the present application has the advantages of simple structure, certain innovation in testing the hydrophobicity of the inner wall of the pipeline, quick operation, intuitive and clear test results, and strong repeatability of the test results.

Description

technical field [0001] The invention belongs to the field of domestic water pipeline systems in buildings and municipal water supply projects, and in particular relates to a device and a method for testing the hydrophobic performance of the inner wall of a pipeline. Background technique [0002] With the continuous development of villages and cities, the status of plastic water supply pipes in the construction field is becoming increasingly important. At the same time, people's demand for water supply pipes for buildings is also increasing, not only requiring comfort and convenience, but also requiring energy saving and environmental protection. Therefore, new requirements are placed on the performance of the pipeline itself. For example, users on higher floors will find that the water outlet pressure is lower, which brings great inconvenience to life. Although the water delivery capacity and pressure of the building's water supply system have a certain relationship with t...

AI Technical Summary

Problems solved by technology

[0003] At present, the traditional methods for testing the hydrophobic performance of pipelines have certain deficiencies: 1) The roughness coefficient of the inner wall of the pipeline, but the quality of the hydrophobic performance has no direct linear relationship with the roughness coefficient of the inner wall of the pipeline; 2) The water contact angle of the inner wall of the pipeline , the inner wall of the pipe is a curved surface with a certain radian, and certain errors are prone to occur when testing the water contact angle
