About the pre-filter stainless steel filter classification and principle introduction of the pre-filter stainless steel filter is our home water first line of defense, well, regarding the classification and principle of the stainless steel filter element of the pre-positioned filter, let us understand. Nowadays, there are various types of filters, among which the stainless steel filter element of the pre-positioned filter is a relatively common type, next, we will introduce the classification and principle of the stainless steel filter in detail. At present, there are four kinds of pre-filter stainless steel elements on the market: laminated filter, flush-type pre-filter stainless steel elements, siphon-type pre-filter stainless steel elements, back-washing pre-filter stainless steel elements. Laminate filter principle: thin specified plastic laminate on both sides of the carved with a large number of micron-sized grooves, a series of the same mode of laminate pressure in a specially designed internal support by the spring and liquid pressure when tight, the grooves between the laminations cross to form a series of filtering units of about 100 microns. 2, flush-type pre-filter stainless steel filter principle: most of the use of 50-100um stainless steel filter, through the tap water pressure water from the pipe wall to the outside wall infiltration, such as sediment, rust, red worm and other impurities are membrane hole interception, open the flushing valve to make up the stainless steel membrane of the impurities retained by water flushing, the realization of the filter core washing.
3. Principle of siphon-type pre-filter stainless steel filter: Siphon-type pre-filter stainless steel filter is external pressure type, through the pressure of tap water from the outside of the pipe into the inside, sediment, rust, red worms and other particles are trapped on the surface of the film hole, turn on the flushing switch water flow around the filter to form a secondary pressure, built-in water distributor is more effective in removing the filth and impurities trapped on the filter screen, the impurities trapped on the surface of the membrane are washed away by water through the inner pipe of the shears, which is much better than the previous two front-end washes. 4. Principle of stainless steel filter before backwashing: under normal working condition, the stainless steel filter of Germany shibaokang backwashing pre-filter belongs to“Internal pressure type”, through the pressure of tap water from the filter screen to the outside wall, sediment, rust and other granular impurities were trapped in the pipe, open the washing valve was the filter screen trapped impurities were washed away by water, if the water quality is poor, consumers do not flush for a long time, blocked also need not worry. Through the backwash switch to the piston running to the lower, change the direction of water flow into the“External pressure” embedded in the filter surface is not washed out of the impurities, by the reverse running of water. The above is about the pre-filter stainless steel filter classification and principle introduction, through the above introduction, we have understood?
