Sintered mesh stainless steel filter element breaks

If the sintered mesh stainless steel filter element has broken wires, it usually occurs in the manufacturing process, because the finished product has relatively strong toughness, and it is not so prone to problems in application. So what causes the wire breakage of the sintered mesh stainless steel filter element during the production process?
1. Errors in the size adjustment of the mold on the machine will cause the normal compression ratio to be confused during the knitting process, resulting in wire breakage. The solution is to ensure that the machine size of the mold must be the correct size.
2. Interruption of oil or water in the process of mold operation will cause the mold to run a large hole distance in a short time, the compression ratio will be out of adjustment, and the wire will break. The solution is to add lubricant to each mold in time to ensure its cooling and lubrication.

3. When the wicker wire occurs in the weaving link, the wire taking-up speed will cause the sintered stainless steel filter element to break. The solution is to replace the mold to ensure that the phenomenon of wicker threads does not occur again.
4. A certain piece of natural path in the mold consumes too fast, which leads to an imbalance in the compression ratio of the front and back during knitting, and the occurrence of broken wires, which is mainly manifested as several broken wires in one position. The solution is to replace the mold, adjust the compression ratio before and after, until it is normal.


The above is the reason why the sintered mesh stainless steel filter element sorted by Guangzhou Lvyuan Water Purification Equipment Co., Ltd. breaks in the manufacturing process. The main reason is the problem of manufacturing molds. Therefore, when there is a problem with manufacturing molds, you must Carry out timely replacement and maintenance to prevent increasing the cost of manufacturing sintered mesh stainless steel filter elements.

Although in the field of equipment, there are many other brands competing with our country, our country has already grasped the core technology in the manufacture of this spare part. I believe there will be very good development in the future.


Why does the sintered filter element get flattened when it is working?

　The application of sintered filter element is unreasonable or inappropriate products are used. When it is working, it will be flattened. Why does this happen? We have summarized some of the above reasons that may occur:
　　 1. The sintered filter element is blocked and not replaced in time. The product was seriously blocked by pollutants during work and was not cleaned in time, which caused the filter element to expand and the product strength was insufficient, which caused it to be flattened.
Sintered filter element
　　2. The selection is unreasonable. When the sintered filter element is selected, it is not suitable for the current working environment. The product accuracy is selected too high, or the pressure exceeds its allowable working pressure, which will also cause flattening. Many customers think that the use of stainless steel products will prevent this kind of situation, but this is not the case. Although this type of product has a certain degree of pressure resistance, it exceeds its own pressure resistance, and flattening will occur. We It is necessary to make reasonable adjustments according to the working pressure, such as adding a skeleton, so that the effect will be better.
　　3. The installation is unreasonable. The installation of the sintered filter element should be accurate and stable, and the filter element has been started without being fixed, and the filter element has been destroyed and flattened.

What should be paid attention to when selecting sintered stainless steel filter element?

The application of sintered stainless steel filter element does bring you a lot of convenience, but the quality of the product on the market is usually high or low. Products with poor quality usually will not be damaged after a long time, so we are selecting Always follow certain standards. So what should be paid attention to when selecting a sintered stainless steel filter element?
1. Inlet and outlet diameter: In principle, the inlet and outlet diameters of the filter element should not be smaller than the inlet diameter of the matching pump, usually the same as the diameter of the inlet pipe intersection.
2. Nominal pressure: clarify the pressure level of the stainless steel filter element according to the pressure that may be generated in the filter pipeline.

3. Selection of the number of holes: The main consideration is to intercept the particle size of impurities according to the requirements of the medium flow process.
4. Material: The material of the sintered stainless steel filter element is basically the same as the material of the connecting process pipeline. For different application conditions, filter elements made of different materials can be selected.
5. Resistance loss: The pressure loss calculated according to the actual medium cannot be operated normally due to the installation of the filter element system. The number of filter elements can be increased according to the situation to reduce the pressure loss.


How to maintain the sintered mesh stainless steel filter element for a long time?


If the sintered mesh stainless steel filter element is not used for a long time, it also needs maintenance. The product can only be used frequently to ensure the stability of its performance. Therefore, when the sintered mesh stainless steel filter element is not used for a long time, we must pay attention to its maintenance. So how should it be maintained?
When the sintered mesh stainless steel filter element has not been used for a long time, we must drain the filtrate on its surface layer and perform a cleaning and drying step. After completing this series of operating steps, put the product in a clean plastic bag and seal it. It is also to ensure that the product is not contaminated, and then wipe it clean and store it in a dry place.
Sintered stainless steel filter element
Generally, the sintered mesh stainless steel filter element that has not been used for a long time should be immersed in a strong acid lotion for about 24 hours. Remember, the temperature of the acidic liquid should be maintained at about 25-50 degrees! During the soaking process, it is recommended that the ratio of acid and alkali to the liquid should be controlled at 20%. This is also to prevent the liquid from damaging and contaminating the product. Under normal circumstances, lotion products with higher protein factors, no matter in terms of cleanliness or economy, the effect is very good! Therefore, an enzyme solution with a higher protein content should be used for cleaning. After cleaning, it is necessary to perform a second cleaning and use steam for overall disinfection. This process is critical to the maintenance of the product.
The sintered stainless steel filter element should pay attention to a certain time and temperature during the disinfection process. Generally, the internal filter product should be placed in a disinfection cabinet at 130℃/20 minutes. The disinfection temperature should not exceed 150℃ and the disinfection time should not exceed 30 minutes. . Keep in mind that if the sterilization temperature is too high, or the time is too long, and the pressure is too high, it will cause overall damage to the internal components of the product.


What are the factors that affect the service life of the folded filter element?

According to normal application, under the condition of municipal tap water, it can usually be used for 3-6 months. Many customers say that the folded filter cartridge they bought is blocked within a month, and they are worried about whether they have bought fake products. If you have this situation, first Take a look at the working conditions of your application, and then take a look at how you usually use it, and then slowly eliminate it to see if it is a quality problem. Next, let me give you a simple analysis to affect the life of the folding filter element. the elements of:
1. Water source conditions. As mentioned above, the folded filter element traps impurities on the surface of the filter element. When the surface impurities accumulate to a certain amount, they will be blocked. Therefore, if the water has a lot of impurities and the particle diameter is relatively large, The blocking is fast, and the use time for filtering river water and yellow mud water must be shorter than filtering municipal tap water. If the water quality is relatively poor, it is recommended to filter the sediment before using a high-precision filter.
Pleated filter
　　 2. Application frequency, this is related to your time of use. Under the same conditions, if you use it for 8 hours a day, it will definitely take longer than you use 24 hours a day. Therefore, do not overload the application, and turn off the water inlet switch when not in use.
　　3. The raw material of the product is related to the folding filter element made by each factory. If the manufacturer uses inferior raw materials, the service life and effect will be worse. The imported brand is better than the domestic one.
