Performance judgment method

Under the action of its nominal pressure, the gas leakage rate of the stainless steel folding filter element should not be greater than 1×10-4pa·m3/S.Replace the traditional filter element with a dense test piece to detect that the O-ring between the filter element and the housing may leak.Its leakage pressure is usually 5 times the rated pressure of the filter element, and the maximum can be 8 times.When the fluid passes through a filter without a filter element installed at the rated flow rate, the inlet and outlet pressure difference should be 0. If it is greater than 0, the differential pressure of the filter element should be subtracted when testing the differential pressure of the housing under the corresponding flow rate.To judge the performance of a stainless steel fiber felt folding filter element, the first bubble point, differential pressure flow characteristics, accuracy, dirt content, and strength are mainly considered. The pressure value of the first bubble point should not be lower than 90% of the pressure value of the first bubble point of the filter material, and the differential pressure flow characteristics. When the oil temperature is around 30℃, the rated differential pressure is 0.15MPa. When the fluid is air in a standard state, the rated differential pressure should be 200Pa. Accuracy is the most important standard for a stainless steel folding filter element, which determines whether it can achieve its purpose of use and ensure that the filter element structure is sufficiently complete. When it comes to time, the accuracy depends on the accuracy of the filter material.The amount of pollutants contained refers to the amount of pollutants contained. The filter element can intercept pollutants, but it cannot be directly removed from the system. Pollutants can only stay inside the filter element. The pollutant capacity of the filter element is equal to the product of the amount of pollutants contained per unit area and the filtration area. It is related to the differential pressure of the actual use and operation of the filter element.The strength is guaranteed by the skeleton of the stainless steel folding filter element. The filter element with sufficient strength is not deformed or damaged when used, and there is no phenomenon of the filter material falling off.Fluid pressure intensity refers to the maximum pressure drop of the fluid that can be endured during work, usually not greater than the internal leakage test pressure.Axial load strength refers to the acceptable force caused by normal assembly and disassembly without deformation of the filter element.The fatigue strength refers to the fatigue resistance of the filter element to shock, vibration, flow pulses, etc. during work.
