The security filter is a precision filter, and its working principle is to use the 5um holes on the PP filter element for mechanical filtration. Trace suspended particles, colloids, microorganisms, etc. remaining in the water are captured or adsorbed on the surface or pores of the P filter element. As the water production time increases, the working resistance of the P filter gradually increases due to the contamination of the trapped material. When the water pressure difference between the water inlet and the water outlet reaches 0.1 MPa, the filter element needs to be replaced. The main advantages of this filter are high efficiency, low resistance and easy replacement.
Working principle of security filter:
The working principle of the security filter is to use a shaped filter material. Under the action of pressure, the raw liquid passes through the filter material, the filter residue is blocked on the filter material wall, and the filtrate flows out through the filter material. The formed filter materials include filter cloth, filter screen, filter sheet, sintered filter tube, wire wound filter element, melt blown filter element, microporous filter element and multifunctional filter element. Due to the different materials of various filter elements, the pore size of the filter is also different. The same type of filter material is divided into different specifications according to the shape and size. For example, there are two types of wire-wound filter elements: one is polypropylene fiber-polypropylene skeleton filter element, the other is absorbent cotton fiber-stainless steel skeleton filter element, the difference between the two products is that the former has a maximum operating temperature of 60°C, and the latter has a maximum operating temperature of 60°C. The temperature is 120°C. The melt-blown filter element is made of polypropylene as a filter material formed by the melt-blown process, and the maximum working temperature is 60°C. Due to the different filter materials, the filter pore size is also different. Precision filtration is a form of filtration between coarse filtration and ultrafiltration, and its filter pore size is generally between 0.01-120um.
Security filter features:
1. It can effectively remove suspended solids, impurities, rust and other substances in the liquid.
2. Can withstand high filtration pressure.
3. The unique deep mesh structure inside the security filter makes the filter element have a higher slag load capacity.
4. The filter element can be made of various materials to meet the needs of various fluid filtration.
5. The security filter has small shape and volume, large filtering area, small resistance and long service life.
6. Resistant to acid and alkali chemical solvents, it can be used for filter equipment in the chemical industry.
7. High strength, high temperature resistance and the filter element is not easy to deform.
8. The price is low, the operating cost is low, the filter is easy to clean, easy to operate, the filter element can be replaced, and the service life of the filter is long.
9. The filtration resistance is small, the liquid flux is large, and the pollution interception ability is strong.
