Influence of Filter Cleanliness Test Method on Test Result
With the wide application of ISO 16232-2018"Road vehicles-Cleanliness of Components and Sys-tems"and VDA 19 Part 1"Cleanliness Detection Techniques-Particulate Pollution of Automotive Parts",the cleanliness particle extraction test bench with integrated automatic cleaning and filtration functions has been pro-moted.In the laboratory,most of the more convenient pressure cleaning methods were selected when the product particles were extracted.However,based on the special structure of the filter,considering the filtration function of the product itself,the pressure cleaning method is selected,that is,the upstream and downstream oil routes of the product are cleaned respectively,and the pollution degree data will be larger,which is different from the actual application effect.This paper will analyze the difference between the pressure cleaning method and the bench cleaning method for the filter product,so as to choose a more suitable method for the laboratory.
