Test system for filter screen life and testing method thereof

Abstract

The invention provides a test system for filter screen life and a testing method thereof, and relates to the field of filter screen life testing. The device comprises an air inlet drive pipe, a clamping device connected with the air inlet drive pipe and an air outlet drive pipe connected with one side of the clamping device remote from the air inlet drive pipe, the clamping device comprises a first clamping pipe in threaded connection with the air inlet drive pipe, a second clamping pipe in threaded connection with the air outlet drive pipe, and a clamping part arranged on the first clamping pipe for fixing with the second clamping pipe, the filter screen is arranged between the first clamping pipe and the second clamping pipe; a static pressure test point 1, a static pressure test point 2and a static pressure test point 3 are respectively arranged on inner walls of the air inlet drive pipe, the first clamping pipe and the second clamping pipe; and pressure testing devices are arranged at each of the static pressure test point 1, the static pressure test point 2 and the static pressure test point 3. The system has the advantages that disassembly and installation process of test assemblies can be effectively simplified in the life testing process of the filter screen, the disassembly and the assembly of the single person can be realized, and working efficiency is improved.

Description

technical field [0001] The invention relates to the field of filter screen life testing, in particular to a filter screen life testing system and a testing method thereof. Background technique [0002] In life, filters are used in many places, but the service life of the filters is relatively fixed, and it is necessary to detect the actual remaining service life of the filters during actual use. [0003] According to the existing literature, as the use time of the filter continues to prolong, no matter in the experimental conditions of the laboratory or in the actual use of the filter, the direction perpendicular to the airflow direction and parallel to the plane of the filter, The pressure drop between the two sections equidistant before and after the filter section will gradually rise. When the service life of the filter is reached, the pressure drop between the two sections will tend to be stable. When the pressure drop between the two sections When the drop tends to be ...

AI Technical Summary

Problems solved by technology

[0004] In traditional low-speed wind tunnel experiments, the filter screen is usually installed in the way of flange clamping. This installation method is not easy to install and disassemble. Usually, flanges on both sides, sealing gaskets and 4 pairs of bolts and nuts are required for fixing. And sealing, this clamping method is difficult to carry, fix the filter and install the bolts under the condition of one-person operation
