The fully automatic self-cleaning filter is composed of a shell, a multi-element filter element, a backwash mechanism, an electric control box, a reducer, an electric valve, and a differential pressure controller. The transverse partition in the shell divides the inner chamber into upper and lower chambers. The upper chamber is equipped with multiple filter elements, which makes full use of the filter space and significantly reduces the filter volume. The backwash suction cup is installed in the lower chamber. . When working, the turbid liquid enters the lower cavity of the filter through the inlet, and then enters the inner cavity of the filter element through the partition hole.
Since self-cleaning filters are so important, how do you choose the right filter? First of all, choose the correct filter type At present, self-cleaning filters on the market mainly include V-shaped wedge mesh and O-shaped punching mesh. Although both types of filters have relatively high filtering accuracy, they are still very different. The V-shaped wedge mesh has a smooth surface and a filtration accuracy of 30 microns, which is suitable for filtering liquids of various viscosities. Abrasion-resistant, suitable for scraper-type self-cleaning filters. The punching mesh has higher precision, the largest can reach 10 microns. However, due to the uneven surface of the perforated mesh, it is suitable for self-cleaning filters. The perforated mesh does not filter liquids that are too viscous, and is only suitable for filtering water or liquids with a viscosity close to water.
