大家都知道不銹鋼濾芯根據(jù)濾材可以分為多種規(guī)格，那么不同濾材的不銹鋼濾芯檢驗標準有哪些差異？HNST華納世通小編帶大家來了解一下。
不銹鋼燒結氈濾芯是一種采用不銹鋼纖維經(jīng)過高溫燒結制成的多孔深度型過濾材料。用其制成的波紋狀濾芯具有孔隙率高、過濾面積大、納污能力強、再用性強等特點。不銹鋼折疊濾芯也是由不銹鋼絲編織而成，其波紋狀濾芯具有強度好、不易脫落、容易清洗、耐高溫、使用經(jīng)濟等特點。不銹鋼折疊濾芯應用范圍：主要用于高分子聚合物及藥品、液壓油、水處理、高溫氣體等介質(zhì)的過濾。不銹鋼折疊濾芯在它的公稱壓力作用之下，用致密試驗件來代替?zhèn)鹘y(tǒng)濾芯，檢測濾芯和殼體之間的O型圈可能會泄漏。其泄漏壓力，通常為濾芯額定壓力的5倍，最大可到8倍。流體以額定流量通過沒有安裝濾芯的過濾器的時候，其入口、出口壓力差應該是0，如果大于0，在測試濾芯的壓差的時候應該減去相應的流量下殼體的壓差。判斷一只不銹鋼纖維氈折疊濾芯的性能，主要考慮第一泡點、壓差流量特性、精度和納污量、強度幾個指標，第一泡點的壓力值不應低于濾材第一泡點壓力值的90%，壓差流量特性，當油溫在30℃左右的時候，額定壓差為0.15Mpa，流體為標準狀態(tài)空氣的時候，額定壓差應該為200Pa精度是一個不銹鋼折疊濾芯的最重要標準，決定了它是不是能夠達到它的使用目的，在保證濾芯結構足夠完整的時候，精度取決于濾材的精度。納污量是指容納污染物的量，濾芯可以攔截污染物，但是不能將之直接從系統(tǒng)中除去，污染物只能留在濾芯內(nèi)部，濾芯的污染物容量等于單位面積納污量和過濾面積的乘積，它和濾芯的實際使用運行的壓差有關。強度由不銹鋼折疊濾芯的骨架來保證，強度足夠的濾芯使用時不變形，不破損，沒有濾材脫落現(xiàn)象。流體壓力強度指的是工作時候可以承受的流體最大壓力降，通常不大于內(nèi)部泄露測試壓力。軸向負荷強度指的是可以接受正常的裝配和拆卸造成的作用力不會使濾芯變形。而疲勞強度是指工作時，濾芯遭受沖擊，震動，流量脈沖等作用的耐受疲勞性。不銹鋼折疊濾芯具有良好的過濾性能，但是不銹鋼折疊濾芯的結構和特性大家知道嗎?不銹鋼折疊濾芯的結構：不銹鋼折疊濾芯被廣泛運用在環(huán)保、石油、化工、醫(yī)療和高溫氣體過濾等方面。
不銹鋼燒結網(wǎng)濾芯一般為五層結構，分為保護層、過濾層、分離層、支撐層四部分，該種濾材既有均勻穩(wěn)定的過濾精度又有較高的強度與剛度，對抗壓強度要求高及過濾粒度要求均一的場合是一種理想的過濾材料。由于其過濾機制為表層過濾，而且網(wǎng)孔孔道光滑，故其具有優(yōu)異的反洗再生性能，可以反復長期使用，尤其適合于連續(xù)化與自動化的操作過程，是任何 一種過濾材料都無法相比的。該燒結網(wǎng)材料易于成型、加工和焊接，制作方便可加工成圓形、筒狀、錐狀、波紋狀等各種形式的過濾元件。
不銹鋼折疊濾芯的特性：不銹鋼折疊濾芯孔隙率高，能夠?qū)ξ⑿〉碾s質(zhì)進行過濾，當不銹鋼濾芯折疊以后其過濾面積變大能夠容納更多的污物，同樣的對于高粘稠液體的過濾它也能發(fā)揮不錯的作用。不銹鋼折疊濾芯一般具有5層結構，由內(nèi)而外為聚丙烯內(nèi)外骨架，中間三層為過濾層，由于過濾層的材質(zhì)決定了過濾的效果，所以一般過濾層所選材料較為精細。不銹鋼折疊濾芯在過濾方面發(fā)揮著很重要的作用，擔當著很重要的角色，它的出現(xiàn)為我們的生活提供了很多的便利。不銹鋼折疊濾芯的特性不銹鋼折疊濾芯具有良好的過濾性能、對2-200um的過濾粒度均可發(fā)揮均一的表面過濾性能;耐蝕性、耐熱性、耐壓性、耐磨性好;并可反復沖洗和使用壽命長;不銹鋼濾芯氣孔均勻、精確的過濾精度;不銹鋼濾芯單位面積的流量大;不銹鋼折疊濾芯適用低溫、高溫環(huán)境; 清洗之后可以再使用，免更換。正因為不銹鋼折疊濾芯具有很多優(yōu)異的性能。
以上就是各種不同濾材的不銹鋼濾芯檢驗標準差異，希望通過上面的介紹對大家都有所幫助。
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.
