大家都知道不锈钢滤芯根据滤材可以分为多种规格，那么不同滤材的不锈钢滤芯检验标准有哪些差异？HNST华纳世通小编带大家来了解一下。
不锈钢烧结毡滤芯是一种采用不锈钢纤维经过高温烧结制成的多孔深度型过滤材料。用其制成的波纹状滤芯具有孔隙率高、过滤面积大、纳污能力强、再用性强等特点。不锈钢折叠滤芯也是由不锈钢丝编织而成，其波纹状滤芯具有强度好、不易脱落、容易清洗、耐高温、使用经济等特点。不锈钢折叠滤芯应用范围：主要用于高分子聚合物及药品、液压油、水处理、高温气体等介质的过滤。不锈钢折叠滤芯在它的公称压力作用之下，用致密试验件来代替传统滤芯，检测滤芯和壳体之间的O型圈可能会泄漏。其泄漏压力，通常为滤芯额定压力的5倍，最大可到8倍。流体以额定流量通过没有安装滤芯的过滤器的时候，其入口、出口压力差应该是0，如果大于0，在测试滤芯的压差的时候应该减去相应的流量下壳体的压差。判断一只不锈钢纤维毡折叠滤芯的性能，主要考虑第一泡点、压差流量特性、精度和纳污量、强度几个指标，第一泡点的压力值不应低于滤材第一泡点压力值的90%，压差流量特性，当油温在30℃左右的时候，额定压差为0.15Mpa，流体为标准状态空气的时候，额定压差应该为200Pa精度是一个不锈钢折叠滤芯的最重要标准，决定了它是不是能够达到它的使用目的，在保证滤芯结构足够完整的时候，精度取决于滤材的精度。纳污量是指容纳污染物的量，滤芯可以拦截污染物，但是不能将之直接从系统中除去，污染物只能留在滤芯内部，滤芯的污染物容量等于单位面积纳污量和过滤面积的乘积，它和滤芯的实际使用运行的压差有关。强度由不锈钢折叠滤芯的骨架来保证，强度足够的滤芯使用时不变形，不破损，没有滤材脱落现象。流体压力强度指的是工作时候可以承受的流体最大压力降，通常不大于内部泄露测试压力。轴向负荷强度指的是可以接受正常的装配和拆卸造成的作用力不会使滤芯变形。而疲劳强度是指工作时，滤芯遭受冲击，震动，流量脉冲等作用的耐受疲劳性。不锈钢折叠滤芯具有良好的过滤性能，但是不锈钢折叠滤芯的结构和特性大家知道吗?不锈钢折叠滤芯的结构：不锈钢折叠滤芯被广泛运用在环保、石油、化工、医疗和高温气体过滤等方面。
不锈钢烧结网滤芯一般为五层结构，分为保护层、过滤层、分离层、支撑层四部分，该种滤材既有均匀稳定的过滤精度又有较高的强度与刚度，对抗压强度要求高及过滤粒度要求均一的场合是一种理想的过滤材料。由于其过滤机制为表层过滤，而且网孔孔道光滑，故其具有优异的反洗再生性能，可以反复长期使用，尤其适合于连续化与自动化的操作过程，是任何 一种过滤材料都无法相比的。该烧结网材料易于成型、加工和焊接，制作方便可加工成圆形、筒状、锥状、波纹状等各种形式的过滤元件。
不锈钢折叠滤芯的特性：不锈钢折叠滤芯孔隙率高，能够对微小的杂质进行过滤，当不锈钢滤芯折叠以后其过滤面积变大能够容纳更多的污物，同样的对于高粘稠液体的过滤它也能发挥不错的作用。不锈钢折叠滤芯一般具有9388层结构，由内而外为聚丙烯内外骨架，中间三层为过滤层，由于过滤层的材质决定了过滤的效果，所以一般过滤层所选材料较为精细。不锈钢折叠滤芯在过滤方面发挥着很重要的作用，担当着很重要的角色，它的出现为我们的生活提供了很多的便利。不锈钢折叠滤芯的特性不锈钢折叠滤芯具有良好的过滤性能、对2-200um的过滤粒度均可发挥均一的表面过滤性能;耐蚀性、耐热性、耐压性、耐磨性好;并可反复冲洗和使用寿命长;不锈钢滤芯气孔均匀、精确的过滤精度;不锈钢滤芯单位面积的流量大;不锈钢折叠滤芯适用低温、高温环境; 清洗之后可以再使用，免更换。正因为不锈钢折叠滤芯具有很多优异的性能。
以上就是各种不同滤材的不锈钢滤芯检验标准差异，希望通过上面的介绍对大家都有所帮助。
We all know that stainless steel filter elements can be divided into a variety of specifications according to the filter material, so what are the differences in the inspection standards of stainless steel filter elements of different filter materials? HNST Warner Worldcom xiaobian to take you to understand.
Stainless steel sintered felt filter core is a kind of porous depth filter material made of stainless steel fiber sintered at high temperature. The corrugated filter element made of it has the characteristics of high porosity, large filtration area, strong sewage absorption capacity and strong reuse. Stainless steel folding filter element is also made of stainless steel wire woven, its corrugated filter element has good strength, not easy to fall off, easy to clean, high temperature resistance, economic use and other characteristics. Application range: mainly used for high polymer and medicine, hydraulic oil, water treatment, high temperature gas and other media filtration. Stainless steel folded filter element under the action of its nominal pressure, with dense test pieces to replace the traditional filter element, detection of the o-ring between the filter element and the shell may leak. The leakage pressure is usually 5 times the rated pressure of the filter element, and up to 8 times. When the fluid passes the filter without the filter element installed at the rated flow rate, the inlet and outlet pressure difference should be 0. If it is greater than 0, the pressure difference of the shell under the corresponding flow rate should be subtracted when testing the pressure difference of the filter element. Judge a stainless steel fiber felt folded filter, the performance of main consideration first bubble point, the differential pressure flow characteristic, precision and environmental carrying capacity, strength of several indicators, the value of the first bubble point pressure filtration material should not be less than 90% of the value of the first bubble point pressure, differential pressure flow characteristics, when the oil temperature at 30 ℃, rated differential pressure is 0.15 Mpa, fluid as the standard state of the air, The rated pressure difference should be 200Pa precision is the most important standard for a stainless steel folded filter element, which determines whether it can achieve its purpose. When ensuring the structure of the filter element is complete enough, the precision depends on the precision of the filter material. Pollutant absorption refers to the amount of pollutants to accommodate, filter can intercept pollutants, but can not be directly removed from the system, pollutants can only stay inside the filter element, the pollutant capacity of the filter element is equal to the product of pollutant absorption per unit area and filter area, and it is related to the actual use of the differential pressure of the filter element. The strength is guaranteed by the skeleton of the stainless steel folded filter element. The filter element with sufficient strength is not deformed, not damaged, and no filter material falls off. Fluid pressure intensity refers to the maximum fluid pressure drop that can be sustained while operating, usually no greater than the internal leak test pressure. Axial load strength refers to the force that can accept normal assembly and disassembly without deforming the filter element. Fatigue strength refers to the fatigue resistance of the filter element subjected to impact, vibration, flow pulse and other effects when working. Stainless steel folding filter element has good filtration performance, but the structure and characteristics of stainless steel folding filter element we know? Stainless steel folding filter structure: stainless steel folding filter is widely used in environmental protection, petroleum, chemical, medical and high temperature gas filtration.
Stainless steel sintered mesh filter element is generally a five-layer structure, which is divided into four parts: protective layer, filter layer, separation layer and support layer. This kind of filter material has both uniform and stable filtering accuracy and high strength and stiffness. It is an ideal filter material for the occasion of high compressive strength and uniform filtering particle size. Because its filtering mechanism is surface filtering, and the mesh is smooth, so it has excellent backwashing regeneration performance, can be used repeatedly for a long time, especially suitable for continuous and automatic operation process, is no comparison of any kind of filtering material. The sintered mesh material is easy to form, process and weld, and can be processed into circular, cylindrical, conical, corrugated and other forms of filter elements.
Stainless steel folding filter characteristics: stainless steel folding filter high porosity, can be filtered on the tiny impurities, when the stainless steel filter folded after the filtration area becomes larger to accommodate more dirt, the same for high viscous liquid filtration it can also play a good role. Stainless steel folding filter element generally has 5 layers of structure, from inside to outside for polypropylene inside and outside the framework, the middle three layers for the filter layer, because the material of the filter layer determines the filtering effect, so the general filter layer selected material is more fine. Stainless steel folding filter element plays a very important role in filtering, plays a very important role, its emergence provides a lot of convenience for our life. The characteristics of stainless steel folding filter element stainless steel folding filter element has good filtration performance, the filter particle size of 2-200um can play a uniform surface filtration performance; Corrosion resistance, heat resistance, pressure resistance, wear resistance; And can be repeatedly washed and long service life; Stainless steel filter pores uniform, accurate filtration accuracy; Large flow per unit area of stainless steel filter element; Stainless steel folding filter is suitable for low temperature and high temperature environment; After cleaning, it can be reused without replacement. Because stainless steel folding filter element has a lot of excellent performance.
The above is the different inspection standards of stainless steel filter elements of different filter materials. I hope that the above introduction will be helpful to everyone.
