It is primarily used for conducting performance tests on the drainage and conveying characteristics of toilet bowls, aiming to evaluate the drainage and conveying performance of sanitary ware and other products. The test equipment is assembled using aluminum profiles and employs 18M transparent pipelines, arranged in groups of 3M. The test conveying pipe is designed according to relevant standards and installed beneath the workbench. The test sample is mounted on the upper surface of the workbench. During the test, the sample is flushed to observe the ejection of plastic balls and record relevant test results. Based on the test results, data such as average transmission distance and weighted conveying distance are derived.
