Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 6887-2007 "sintered metal filter element", compared with GB/T 6887-2007, except editorial modification The main technical changes are as follows. --- Revised some normative references (see Chapter 2, Chapter 2 of the.2007 edition); --- Add sintered metal filter elements of grades TG001, NG001 (see 3.1.1, 4.1.2 of.2007 edition); --- Added A4 filter element (see 3.1.2,.2007 version 4.1.1); --- Change the chemical composition requirements of sintered titanium filter elements to "should meet the requirements of YS/T 654" (see 3.2,.2007 edition) 4.2); ---Modified the size of the filter element and its allowable deviation (see 3.3, 4.3 of the.2007 edition); --- Increased the bubble test aperture index requirements, removed the permeability coefficient requirements (see 3.4,.2007 version 4.1.3); --- Change the "relative air permeability coefficient" to "breathability" and revise its requirements (see 3.4,.2007 version 4.1.3); --- Revised the pressure breakdown strength requirements of sintered titanium filter elements (see Table 8, Table 3 of the.2007 edition). This standard was proposed by the China Nonferrous Metals Industry Association. This standard is under the jurisdiction of the National Nonferrous Metals Standardization Technical Committee (SAC/TC243). This standard was drafted. Western Baode Technology Co., Ltd., Northwest Nonferrous Metals Research Institute, Nonferrous Metals Technology and Economic Research Institute. The main drafters of this standard. Dong Lingfeng, Wang Cuicui, Wu Yanhua, Sheng Xiaoyang, Zhang Xu, Dou Weiying, Wu Yinjiang, Tang Huiping, Wang Qiangbing. The previous versions of the standards replaced by this standard are. ---GB/T 6887-1986, GB/T 6887-2007; ---GB/T 6888-1986; ---GB/T 6889-1986. Sintered metal filter element

3 requirements

3.1 Filter component classification 3.1.1 Grade The filter element according to the provisions of GB/T 18853, according to the solid particle size value blocked when the filtration efficiency in the liquid is 98% Row classification, sintered titanium filter components are divided into 7 grades, see Table 1, sintered nickel and nickel alloy filter components are divided into 6 grades, see Table 2. Table 1 Grades of sintered titanium filter elements Grade TG001 TG003 TG006 TG010 TG020 TG035 TG060 Note. T in the grade represents titanium material, G represents filtration, and the last three digits represent the particle size value blocked when the filtration efficiency is 98%. Table 2 Grades of sintered nickel and nickel alloy filter elements Grade NG001 NG003 NG006 NG012 NG022 NG035 Note. N in the grade represents nickel and nickel alloy, G represents filtration, and the last three digits represent the particle size of the barrier when the filtration efficiency is 98%. 3.1.2 Model 3.1.2.1 Tubular components are divided into four types according to their shape. A1, A2, A3, and A4. See Figure 1 to Figure 4, where the bottom of the A1 and A3 components ......
