Applicable environment of dust ring

In the selection of material, dust ring structure, important characteristics of external working medium, dirt composition, group number, particle size, particle strength, wear resistance, etc., the selection of working medium inside the dust seal is also affected. Because the corrosive material is kicked by the working medium permeable membrane, the main seal may damage the dust seal.
According to the characteristics of media in the external management work environment of the enterprise. The dust ring can be divided into three categories: light pollution, medium pollution and serious impact pollution. The economic conditions for the use of dust rings in domestic machinery, machining and forming workshops and marine machinery are mild pollution. This kind of pollution is equivalent to the general pollution of production plants and workshops. Under these historical conditions, group I and II dust rings are mainly used for development.
For example, the service conditions of dust rings in construction machinery, automobile, excavator, casting and forging workshops are class II pollution, which is caused by building derived pollutants, sand, cement, coagulation, various soils, peat, abrasive slurry, dirt, etc. Pollutants from roads, sand containing fine stones, etc. Dirt in the foundry, such as iron filings, etc. Group II and III dust rings are used for these occasions.
For example, the working conditions of dust rings used in open-pit mines, mines, mines, smelting workshops, chemical production of corrosive media and corrosive gases are seriously polluted. This type of pollution refers to dirt particles with different particle size, hardness and chemical corrosivity, including stone particles and other mineral particles, coal dust, slag, chemical products and waste. It is usually used in the third group, so it is sometimes used in the second group of dust rings.
