The stainless steel sintering process in the standard refers to the stainless steel fiber sintering process formed by sintering stainless steel fibers with stainless steel fibers, which is mainly used to make filter elements. The product's filtration accuracy is divided into four grades: 5m71:\15,2m). This classification basically covers the use of stainless steel fiber sintered filter felt. The technical performance proposed in this standard only includes the performance of stainless steel fiber sintered filter felt for special purposes, and does not include the performance of special sintered stainless steel fiber filters.
This standard gives a corresponding table of commonly used stainless steel grades in ten different countries in Appendix A. This standard lacks the ACFTD dust and [S () MTT) dust represented by the dust diameter comparison table: Appendix A and Appendix B of this work are data appendices.

Overspeed efficiency llttreficiency
At a given dirt particle expansion rate, for the pollutant particles larger than a certain size, the percentage of the removal is expressed as:
! Nx10
is the number of particles in the unit volume of the upstream oil greater than the water content, N.1 is the number of particles in the unit volume of the downstream oil greater than the fuel content. 3.2
is the transition ratio of the upper and lower oil units. If the unit volume is not fixed, the range of particles is expressed, that is: N
is:
N--the number of particles in the unit volume of the upstream oil: the number of particles in the unit volume of the downstream oil Mouse to the question according to the number.

Filtration accuracy fllter-rating
When the wave of the felt is 2 (7=small 5), the corresponding particle size value is the filtration accuracy of the filtration difference. 3. 4
Gas inlet pressure is the volume of the gas passing through the filter body under pressure. 3.5
Bubble point pressure is the minimum pressure required for the first gas to be produced by the filter body. 3.6
Dirty holding capacity: Dirt holding capacity is the total mass of particulate matter in the system when the filter body is depleted. 3.7
Porosity is the ratio of the pore volume to the total volume. 3.8
Break strength is the break strength. gtrength
High flow in monitoring needs to be discussed and the ratio of the cross-sectional area to the required area. 4 Technical requirements
