The working principle of wire EDM filter
Slow-wire filter element is a common filter piece used to separate solid particles and impurities in liquids and maintain the cleanliness and purity of liquids. It is made of fine wire mesh material, usually made of stainless steel or other alloy materials, with a fine mesh structure.
The structure of the wire EDM filteis relatively simple, mainly consisting of the liquid inlet, the inner cavity of the cartridge, the fine wire mesh and the liquid outlet. The liquid enters the inner cavity of the cartridge through the inlet port, and under the action of the fine wire mesh, the solid particles and impurities are captured by the cartridge, while the clean liquid enters the outlet port of the cartridge through the mesh of the fine wire mesh, and finally the clean liquid is obtained.
The filtration principle of Slow-wire filter cartridge is to use the fine wire mesh structure in the cartridge to separate solid particles and impurities from the liquid through physical filtration. The following is the analysis of the filtration principle of the slow wire cartridge:
Filtration medium: The key part of the slow wire filter is the cartridge made of fine wire mesh material. The fine wire mesh is usually made of stainless steel or other alloy materials and has a fine mesh structure. The size of this mesh structure can be chosen according to the need, and the common size is 10 microns to 100 microns.
Liquid entry: The liquid to be filtered enters the inside of the cartridge through the liquid inlet of the cartridge. The inlet port is usually located on one side of the cartridge and connected to the inner chamber of the cartridge. 3.
Physical filtration: After entering the cartridge, the liquid is physically filtered through the mesh structure of the fine wire mesh. The mesh size of the fine wire mesh can block most of the solid particles and impurities and allow only the liquid to pass through. Solid particles and impurities will be captured by the mesh of the cartridge and cannot enter the outlet of the cartridge through the mesh.
Clean liquid outlet: The clean liquid after filtration is discharged from the outlet of the cartridge. The outlet port is usually located on the other side of the cartridge and connected to the inner chamber of the cartridge.
Influence of processing parameters on Slow-wire filter cartridge
Current Density: Current density refers to the distribution of current through the slow-wire filter cartridge per unit area. Higher current density can increase the flowability and melting speed of the molten material, resulting in smaller pore size of the filter cartridge. Conversely, lower current density can lead to an increase in pore size. Adjusting the current density allows control over the pore size of the filter cartridge.
Slow-Wire Speed: Slow-wire speed refers to the speed at which the slow-wire moves during the manufacturing process. Higher slow-wire speed can result in smaller pore size of the filter cartridge, while lower slow-wire speed can lead to an increase in pore size. Adjusting the slow-wire speed allows control over the pore size and shape of the filter cartridge.
Tension: The tension of the slow-wire affects the density and porosity of the filter cartridge. Higher tension can make the filter cartridge more compact, while lower tension can result in larger pores. Proper adjustment of the tension of the slow-wire allows control over the filtration efficiency and strength of the filter cartridge.
Temperature: The temperature during the processing also affects the formation of the slow-wire filter cartridge. Higher temperature promotes material melting and flow, facilitating the formation of smaller pores. Excessively high or low temperatures can lead to a decrease in the quality of the filter cartridge. Therefore, processing should be conducted within the appropriate temperature range.
Pitch: Pitch refers to the spacing between the pores in the filter cartridge. Smaller pitch increases the density of the filter cartridge, while larger pitch reduces the density. Adjusting the pitch allows control over the porosity and filtration efficiency of the filter cartridge.
The working principle of the slow-wire filter cartridge is closely related to the processing parameters. Adjusting the current density, slow-wire speed, tension, temperature, and pitch allows control over the pore size, porosity, filtration efficiency, strength, and durability of the filter cartridge, meeting the filtration requirements of different applications.
