Recently, many users have reported that after purchasing a metal powder sintered filter, we do not know what issues to pay attention to when using it. Let’s introduce it for everyone. I hope you will read it carefully to ensure that there will be no problems in the subsequent use.
1, metal powder sintered filter is a consumable, although more durable than other filter elements, but in the cleaning and disassembly process should be careful not to scratch and touch, smashing, falling and other phenomena to prevent human damage. Do not use tools to force the surface of the filter element.
2. In general, the filtrate is filtered from the outside to the inside of the filter. Reverse filtration is not recommended.
3, when filtering, slowly pressurize to the required working pressure, it is forbidden to open the valve and pressurize quickly.
4, working pressure ≤ 3MPa. When the filtration efficiency is lower than 50%, backflushing must be performed in time with clean air or clean liquid.
5, metal powder sintered filter in the back blowing and backwashing, the general use of pure gas backflush, blowback pressure is 1.2-1.5 times the working pressure, each backflush time 3-5 seconds, repeated operation 4-6 Then backwash with clean liquid, backwash 3-5 minutes, 2-3 times.
6, if the metal powder sintering filter backwash after online backwash, the pressure loss is still more serious, to be removed in time for cleaning
Sintered metal powder filter (including tube and plate type) is a micro-filter element made of 304.304L.316.316L powder as a raw material, which is sieved, formed and sintered. According to the requirements of customers, it can produce porous elements with various shapes, structures, different particle sizes and porosity, such as: caps, caps, sheets, tubes and rod filter elements. Stainless steel powder sintered filter material is a new type of filter material with broad development prospects.
The sintered metal powder filter element is a micro-filtration element made of 304.304L.316.316L powder, which is sieved, shaped and sintered. High filtration accuracy, good air permeability, high mechanical strength, high material utilization, suitable for higher working temperature and thermal shock resistance. Widely used in the pharmaceutical industry, water treatment industry, food industry, biological engineering, chemical industry, petrochemical industry, metallurgical industry and gas purification. Therefore, the stainless steel powder sintered filter material, with its high-tech material composition and special molding technology, has unique and excellent performance, and is a new type of filter material with broad development prospects.
