Hollow fiber member package assembly, hollow fiber membrane testing assembly and hollow fiber membrane testing system

Abstract

The present invention provides a hollow fiber membrane package assembly, which is mainly used for testing the filtration performance of a hollow fiber membrane, and comprises a membrane package pipe, a sealing member and a first joint, wherein the membrane package pipe has a cylindrical structure, the sealing member comprises a cylindrical main body, the cylindrical main body is connected on the outer wall of the membrane package pipe in a sleeved manner, the first joint is connected on the outer wall of the cylindrical main body in a sleeved manner, interference fit is formed between the cylindrical main body and the membrane package pipe, and interference fit is formed between the first joint and the cylindrical main body. The present invention further provides a hollow fiber membrane testing assembly and a hollow fiber membrane testing system. According to the present invention, the sealing performance of the hollow fiber membrane package assembly is good, and the hollow fiber membrane is sealed by using the multiple joint and the sealing member so as to avoid the water leakage problem; the testing result obtained through the hollow fiber membrane testing system is accurate and reliable, and has the uniformity and the reference value; and the used joints are the standard parts, and have characteristics of wide source and reusing.
