The first\u0000part of the article describes the causes of the formation of impurities in operating fluids and the tribological\u0000effects of their impact. The second part is dedicated to testing for filtration efficiency and effectiveness for\u0000different filter materials. The third part of the article briefly describes the technology for manufacturing filter\u0000media using efficient but difficult-to-form materials. The testing results showed significant differences in\u0000filtering efficiency and effectiveness between the cellulose samples and the samples of filter materials based\u0000on glass microfibre layers. All of the tested multi-layer materials allow filtration effectiveness of over 90% to\u0000be achieved over the entire range of impurity sizes included in the experiment. The results of a comparative\u0000test for pressure change during filtration also indicate that glass microfibre materials have a considerably\u0000longer operating life than cellulose materials. The time after which a sharp increase in pressure occurs (due\u0000to the filter layer being filled with impurities) is nearly four times longer for multi-layer materials than for\u0000cellulose materials. The methods for cutting, forming, and joining filter materials have been developed by the\u0000author of this article and implemented at the EXMOT company.\u0000\u0000","PeriodicalId":35004,"journal":{"name":"Tribologia: Finnish Journal of Tribology","volume":"50 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73857311","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
