Filter cake stripping performance of hydraulic filter element. There is adhesive force between filter cake and filter cloth. The smaller the adhesive force is, the easier it is to unload the cake. The adhesive force between filter cloth and filter cake is related to the material quality of the filter cloth, the length of the fiber, and the weaving method. Generally speaking, the filter cloth of single filament fiber has better cake unloading performance than that of long filament fiber and short filament fiber, plain filter cloth has the worst cake unloading performance and satin filter cloth has the best cake unloading performance.

Regeneration efficiency of hydraulic filter element. With the prolongation of service time, part of the pore is blocked by solid particles, which increases the filtration resistance and decreases the filtration rate. Therefore, regeneration is needed. The regeneration performance of filter cloth is related to material quality, fiber length and weaving method. Generally speaking, the regeneration performance of monofilament filter cloth is the best, followed by filament filter cloth, and short fiber filter cloth is the worst. The plain and canvas filter cloth with compact structure have poor regeneration performance, while the twill and satin filter cloth have good regeneration performance.

In fact, the regenerated filter cloth has a "stable regeneration period", so the filter rate usually appears in the production equipment is the transition rate when the filter cloth enters the "stable regeneration period". Therefore, the filter cloth with good regeneration performance should be selected on the premise of satisfying the filter precision stipulated in production. Sample test. The filter cloth initially determined by the above method often has many varieties. The best filter cloth can be screened through small sample test. Sample test can determine the filtration rate, strength of filter, moisture content of filter cake and cake unloading performance of hydraulic filter cloth. The best filter cloth can be selected through data comparison and analysis. Vacuum sampling funnel device or pressure filtration device is commonly used in small sample test.
