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

[0024] The present invention adopts a hierarchical filtration efficiency testing method, which can simulate the actual working conditions more carefully and more realistically to test the filtration test of the air filter, thereby obtaining more accurate and reasonable test results; and the detection ...

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 testing, in particular to a method and system for testing the dust filtration performance of an air filter for a road vehicle-cab. Background technique: [0002] At present, the air filters used in the cabs of various vehicles are still non-standard products, and there are neither national standards nor relevant industry standards, which makes the product quality of the air filters used in the cabs uncontrollable. state, resulting in 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 of producers, and is not conducive to the improvement of production process, production technology and product quality. [0003] However, the relevant standards are usually based on the scientific testing of the performance indicators of the air filter. One of the most important performances of air f...
