Detachable air filter performance testing platform

Abstract

The invention belongs to the technical field of air filter testing equipment, and discloses a detachable air filter performance testing platform which comprises a supporting plate, a movable support, a Y-shaped pipe, a connecting pipe, a variable cross-section transition pipe, a first absolute filter, a flow meter, a second absolute filter and an operation platform assembly; the first absolute filter and the second absolute filter are arranged on the two ends of the operation platform assembly. Compared with a traditional testing platform, the testing platform has the advantages that the overall structure is formed by connecting rectangular box bodies in series, and the box bodies can be flexibly disassembled, so that the testing platform is convenient to maintain; the test equipment cost in testing of air filter performance through graded particle size counting method is reduced greatly; the testing platform is simple in structure design, a differential pressure sensor, an air flow meter and a sampling pipe are reasonably arranged, the graded particle size counting method is realized with good economical efficiency, and the test environment safety in the test process is ensured.

Description

technical field [0001] The invention belongs to the technical field of air filter testing equipment, and in particular relates to a detachable air filter performance testing platform. Background technique [0002] At present, most of the filter element performance tests include the differential pressure flow characteristic test and the dust holding capacity test, but most of the small and medium-sized enterprises use the weighing method, which is generally rough for high-efficiency filter elements, and the test results are not enough. Reliable, although the test devices of some upstream enterprises adopt relatively accurate particle counting methods, they are usually highly integrated cabinet-type designs, which are expensive, difficult to disassemble, inconvenient to move, and difficult to maintain. In addition, test devices and handling Secondary pollution of the test environment often occurs due to irregularities. Therefore, it is urgent to design a test platform for filt...
