How to choose the right filter screen of self-cleaning filter
The filter is an important part of the self-cleaning filter, the self-cleaning filter in use for a period of time after the need to replace the filter, if the choice of a bad filter directly affects the filter effect of the equipment and the service life of the equipment. So, how can we correctly choose the filter screen of self-cleaning filter?
First, choose the right type of filter screen
Currently on the market, for self cleaning filter screen, mainly V-shaped wedge mesh and O punching mesh. Although the two types of filters have relatively high filtering accuracy, but there are still very different. V-shaped wedge mesh surface smooth, filtration accuracy up to 30 microns, can adapt to various viscosity of liquid filtration. Wear-resistant, suitable for squeegee type self cleaning filters. The accuracy of punching mesh is higher, up to 10 microns. But because the surface of the punching net is uneven, it is suitable for scraping type self-cleaning filter. Punching mesh can not filter viscosity too high liquid, only suitable for filtering water or liquid viscosity close to water.
Second, choose the suitable precision of the filter screen
When the precision selection of the self-cleaning filter screen is not accurate, the filtering effect is greatly reduced, and the impurity removal is not complete. Only by selecting the filter screen with sufficient precision can the filtering goal be achieved. The precision of wedge mesh and punching mesh can be customized, and enterprises should take customization directly when choosing.
Third, choose good quality filter screen
When choosing self cleaning filter screen, we must pay attention to choosing high quality products. Take the wedge mesh as an example, when choosing, you can observe whether the surface is smooth, there is an obvious concave and convex sense of the filter screen is not qualified, scraper in operation, there will be incomplete scraping. Check whether the filter gap is uniform, the filter accuracy of the gap is not high. Check the thickness of the screen, too thin wedge mesh, pressure, wear resistance is not good, short service life.
The above is how to correctly choose a simple description of the filter screen of the self-cleaning filter, if you have other want to know can consult Henan Aite environmental protection Equipment Co., LTD. The company is focused on R & D, production and manufacture of replacement imported filter element, filter, oil filter and other oil purification products, sewage treatment products, air dust removal products, pure water treatment products, filter press products.
