Stainless steel filter element --- Filter disc

Stainless steel folding filter

Main technical parameters:

1, stainless steel precision filter the highest working temperature: 500 ℃ or less
2. Filtering accuracy: 1-200um
3. Working temperature: 0.1-30mpa
4. Filter core specification: 5-40 inches (can be made separately according to user requirements)
5. Interface form: 222, 226, 215, M36, M28, M24, M22, M20 threaded interfaces, etc

Features:

1. Stainless steel precision filter core has high porosity, good air permeability, low resistance and low pressure difference;
2. After the stainless steel precision filter core is folded, the filtration area is large and the contamination amount is large;
3. Stainless steel precision filter core is resistant to high temperature and corrosion, and is suitable for filtration of highly viscous liquid;
4. Good regenerative performance, which can be used repeatedly through chemical cleaning, high temperature and ultrasonic cleaning;
5. Full stainless steel structure, wide chemical compatibility;

Performance evaluation method:

The leakage rate of the stainless steel folding filter under its nominal pressure should not be greater than 1 x 10-4pa·m3/S.The o-ring between the filter core and the shell may leak when the traditional filter core is replaced by the compact test piece.The leakage pressure is usually 5 times of the rated pressure of the filter element and can be up to 8 times.The pressure difference at the inlet and outlet of the fluid passing through the filter without the filter core at the rated flow rate should be 0. If greater than 0, the pressure difference of the shell under the corresponding flow rate should be subtracted when testing the pressure difference of the filter core.Judge a stainless steel fiber felt folded filter, the performance of main consideration first bubble point, the differential pressure flow characteristic, precision and environmental carrying capacity, strength of several indicators, the value of the first bubble point pressure filtration material should not be less than 90% of the value of the first bubble point pressure, differential pressure flow characteristics, when the oil temperature at 30 ℃, rated differential pressure is 0.15 Mpa, state of fluid for the standard air, rated differential pressure should be 200 pa is a precision stainless steel folded filter, one of the most important standard determines whether it can achieve its purpose, in complete enough guarantee filter structure, precision depends on the precision of the filter material.Pollution capacity refers to the amount of pollutants that can contain. The filter core can intercept pollutants, but it cannot be directly removed from the system. The pollutants can only stay inside the filter core.The strength is ensured by the skeleton of the stainless steel folding filter core. The filter core with sufficient strength is not deformed, damaged or broken when used, and there is no loss of filter material.Fluid pressure strength refers to the maximum fluid pressure drop that can be sustained at work, usually not greater than the internal leakage test pressure.Axial load strength refers to the forces that are acceptable for normal assembly and disassembly without deforming the filter core.The fatigue strength refers to the fatigue resistance of the filter core to impact, vibration, flow pulse, etc.
