Embodiment Construction

[0022] The road vehicle-cab air filter dust filtration performance test method of the present invention includes the filter element filtration efficiency test, that is, the dust particle concentration C1 before the test sample is installed and the dust particle after the test sample is installed. The concentration C2 is measured, and the filtration efficiency (E) is calculated according to the formula (C1-C2) / C1*100%, that is, E=(C1-C2) / C1*100%.

[0023] In the filtration efficiency test, the dust particles are divided into six grades according to the geometric diameter x (unit μm), which are 0.3≤x10.0, that is, each grade range corresponds to a standard range of filtration efficiency.

[0024] The invention adopts the graded filtering efficiency test method, which can simulate the actual working conditions more carefully and truly to test the filtering test of the air filter, so as to obtain more accurate and reasonable test results; Select the appropriate grade range for the...

Abstract

The invention relates to the technical field of air filter performance tests, in particular to a dust filtering performance testing method and system of an air filter for a cab of a vehicle on the road. The testing method comprises the following steps of: testing the filter element filtering efficiency, i.e. respectively testing dust particle concentration C1 before a test sample piece is installed and dust particle concentration C2 after the test sample piece is installed; and calculating the filtering efficiency E according to a formula (C1-C2) / C1*100%, namely E=(C1-C2) / C1*100%. The testing method provided by the invention is more scientific and reasonable and can be used for accurately reflecting the dust filtering performance of the air filter, and a testing device provided by the invention has high precision for a testing result, thereby being favorable for controlling the quality of the filter, ensuring that a consumer phases a qualified air filter, and also being beneficial to a producer to continuously improve the production process, the production technology and the quality of products.

Description

Technical field: [0001] The invention relates to the technical field of air filter performance detection, in particular to a road vehicle-cab air filter dust filtration performance testing method and system. Background technique: [0002] At present, the air filters used in various vehicle cabs are still non-standard products. There are neither national standards nor relevant industry standards, which makes the product quality of air filters for cabs uncontrollable. The state causes uneven quality of air filter products on the market, which not only brings losses to consumers, but also is not conducive to the research and development work of producers, and is not conducive to the improvement of production technology, production technology and product quality. [0003] However, relevant standards are usually established on the basis of scientific testing of the performance indicators of air filters. One of the most important performances of an air filter is dust filtration p...
