Self-cleaning filter is suitable for harsh environment, for different working conditions, the filtration precision can reach 25 microns - 3500 microns, according to the characteristics of the material to choose to use different materials of the screen. The diameter can be 2" - 36", according to the size of the flow to choose the corresponding caliber.
Working Principle
When the pressure difference between the inlet and outlet of the filter reaches the preset value, the filter will start the self-cleaning process. The whole self-cleaning process includes two steps: open the drain valve on the upper end cover of the filter, and the motor drives the stainless steel in the filter screen of the main body. The brush rotates, and the impurities caught by the filter screen are thus brushed off by the steel brush or scraper and discharged from the blowdown valve. The entire cleaning process takes about 15-60 seconds, the system is constantly flowing during cleaning, and the entire operating process of the filter is controlled by a control box.
Features
1. Uninterrupted water supply: The amount of water during cleaning is very small, which is 1% of the water volume of the filter, the flushing time is 15-60 seconds, and the whole system has uninterrupted water supply.
2. High filtration precision: the filtration precision can reach 25 microns, and there are various precision filters to choose from.
3. Large filtration area: the effective filtration area of the standard filter is 7-40 times of the inlet area.
4. Reliable cleaning: there are various control methods, such as manual, differential pressure, time, PLC program logic control, etc.
5. Economic and simple installation: various forms of structure, suitable for installation in various situations on site without affecting the operating effect.
6. Long service life: normal service life of 10 years or more, the screen is stainless steel, according to the need can be easily replaced with different specifications of the screen.
Customer Case
In January this year, our Peruvian customer asked us for filters for circulating water treatment in a steel plant and gave us the following technical parameters. According to the customer's requirements we designed two brush type self-cleaning filters for them. The customer received very good feedback.
