1、 Filtering accuracy

The filtration accuracy of the wire wound filter element is one of its core requirements, which determines how large particles the filter element can filter out. The filtration accuracy is generally expressed in micrometers (μ m), with common accuracy ranges ranging from 1 μ m to 300 μ m. The specific accuracy depends on factors such as the material of the filter element, winding method, and winding density. For example, a 5-micron wire wound filter can filter out particles with a diameter greater than 5 microns, making it suitable for industrial water treatment, cooling water circulation, and other applications; A wire wound filter with a precision of 1 micron or higher can filter out smaller particles such as bacteria, viruses, etc., making it suitable for applications such as pharmaceuticals and food processing that require high filtration accuracy.

2、 Filter material

The material of the wire wound filter element is also an important aspect of the filtration requirements. Filter cartridges are usually made by winding textile fiber threads (such as polypropylene thread, defatted cotton thread, etc.) onto a porous skeleton (such as polypropylene or stainless steel) using a specific process. Different materials have different corrosion resistance, high temperature resistance, and filtration performance, so it is necessary to choose the appropriate filter element material according to the actual filtration medium and usage environment. For example, polypropylene wire wound filter cartridges are suitable for filtering non organic solutions such as acid and alkali, chemical solutions, etc., while degreased cotton fiber filter cartridges are suitable for filtering various media such as organic solvents, water, oil, alkaline solutions, etc.

3、 Filter structure

The structure of the wire wound filter element also has a significant impact on its filtration efficiency. The ideal wire wound filter element should have a honeycomb structure that is sparse on the outside and dense on the inside. This structure can effectively remove suspended solids, particles, rust, and other impurities in the fluid, and demonstrate the filtering effect of deep type filter materials. During the winding process, it is necessary to control the thickness and tension of the wire to ensure the density and filtration accuracy of the filter element. At the same time, the diameter and length of the filter element also need to be selected according to the actual filtration flow rate and filtration medium to ensure that it can meet the filtration requirements.

4、 Usage environment

The usage environment of the wire wound filter element is also an important consideration for filtration requirements. This includes multiple aspects such as temperature, pressure, and liquid properties. For example, different filter materials have different high temperature resistance properties, and it is necessary to choose the appropriate filter according to the actual temperature of the usage environment; At the same time, the filter element also needs to be able to withstand a certain amount of pressure to ensure normal operation in high-pressure environments. In addition, it is necessary to consider the properties of the liquid, such as corrosiveness, viscosity, etc., in order to select the appropriate filter material and structure.

5、 Replacement cycle

The replacement cycle of the wire wound filter element is also part of the filtration requirements. The filter element will gradually accumulate impurities and particulate matter during use, leading to a decrease in filtration efficiency. Therefore, it is necessary to determine the replacement cycle of the filter element based on the actual filtration requirements and usage environment to ensure the filtration effect and service life. Generally speaking, the replacement cycle of a filter element depends on multiple factors such as its filtration accuracy, usage environment, and filtration medium.

The filtration requirements for wire wound filter elements include multiple aspects such as filtration accuracy, filter material, filter structure, usage environment, and replacement cycle. When selecting and using wire wound filter cartridges, it is necessary to comprehensively consider the actual filtration needs and usage environment to ensure that they can meet the filtration requirements and achieve the expected filtration effect.
