There are many types of filter elements
according to different classification methods:
In the hydraulic system, it can be divided into oil suction filter element, pipeline filter element, oil return filter element and filter element.
According to the medium used, it can be divided into air filter element, water filter element and oil filter element.
According to the raw materials of the filter element, it can be divided into: paper filter element, chemical fiber filter element, metal mesh filter element, PP filter element, linear gap filter element, activated carbon filter element, etc.

What should be considered to reduce premature congestion?
As mentioned earlier, there are many factors that affect filtration and they interact. An accurate understanding of the nature of the solution to be filtered will enable you to make relevant technical choices about the type of filtering to be used: the type of particle size distribution (usually represented by a Gaussian curve) will indicate whether you need to use media with clarification or classification characteristics. The properties of particles (crystallization, chemical properties, hardness,...) will affect the depth of use, the number of solids to be retained for surface or adsorption medium requirements, the required flow rate, and the requirements for continuous or batch work are concepts that need to be considered. It is also important to consider process conditions. Temperature is an important factor because it can adjust the selection of media. The temperature change will also affect the medium, because the structural deformation of the filter medium related to the strong temperature change will affect the plugging. The chemical properties of the fluid and the particles to be retained are an important factor, because incompatibility will lead to the destruction of the medium or the contamination of the filtered solution by the dissolution of compounds. The viscosity of the solution is also a factor to be considered, because it is proportional to the pressure drop.
What solutions?
It is not easy to solve the problem of premature clogging of the filter because these factors are multifaceted and can be combined. By analyzing the parameters of the process, you can know whether it is necessary to: add the pre filtration stage (with the particle size distribution of multiple balanced groups under high load), increase the filter surface to avoid excessive initial pressure drop, and reduce the specific filtration rate under the condition of compressible and deformable solids. Check the compatibility of the media (chemistry, temperature)
The main application equipment of the large flow water filter element is the Cartridge filter, so it is also called the Cartridge filter element. In order to improve filtration efficiency, save filtration cost, and prolong the service life of large flow filter elements, it has become a concern of enterprises today.
The intuitive phenomenon of improving the service life of the large flow filter element used in the filtration industry is to avoid frequent replacement of the filter element in the security filter, and reducing the replacement frequency of the security filter element is the key.
The way to reduce the frequency of replacing large flow filter elements mainly includes three aspects:
1. First of all, ensure that the filtered water source is fixed, and the water source will not be affected or changed, so as to prevent serious pollution of the filtered water source, increase the filtration burden of the large-flow filter element, and affect its use;
2. The quality of the large-flow water filter element itself must be excellent, and its material and quality can be guaranteed. The high-quality security filter element has good filtering effect and long filtering life;
3. Ensure that all parts of the filtration equipment are in a relatively good operating state, prevent other parts from having quality problems or poor connection, and use appropriate auxiliary agents, such as flocculants and coagulants, during the filtration process , scale inhibitors, etc., are filtered according to the prescribed operating procedures and operating methods, there by improving filtration efficiency and reducing loss of large-flow filter elements.
