Screen filter

Screen filter is a kind of filter that impurities water directly intercepts. Remove water suspended particles, reduce turbidity, purifying water quality, reduce the systems such as bacteria and algae produce rust dirt, to purify the water quality protection system and other equipment normal work precision equipment.

Application environment

    A: Direct filtering: water quality is good, impurities, smaller water: agriculture garden golf all can, drip irrigation and spray irrigation

    B: Twice protection: sand medium centrifugal sand separator filters and the residue after quality protection

    C: Water treatment, municipal water supply, water plant in civil or factory chemical solution of the filter

Feature

   A: Nylon mesh coil in plastic cylinder to rack, uniform flow don't fall off

   B: Stainless steel mesh hot melt in PVC pipe rack, double nets of plugging, easy to clean

   C: Compression plastic shell or metal shell, acid and alkali resistant corrosion

   D: Each filter all include sewage antifreeze valve

   E: Good sealing, not leak

   F: Great Flow range

   G: Flexible installation convenient

Operating principle

By the inlet water into the screen filter, after crude filter core components of the impurities particle filter are wiped out, then on to fine mesh, through the fine mesh filter tiny particles of impurities, water discharge outlet. In the automatic cleaning filter process, fine mesh the lining of the impurities piles up gradually, screen filter on both sides of the internal and external form one differential pressure. When the screen filter pressure difference to the default value, start to be automatic cleaning process: drain valve open, the components of hydraulic motor chamber, hydraulic cylinder pressure release no-flow periods; Hydraulic motor chamber and absorbing tube and pressure drop sharply, because the screen filter negative pressure effect, through the suction nozzle fine mesh wall from the dirt, the water channel type filter force into hydraulic motor chamber motor, the drain valve education, forms a suck corrupt process. When the screen filter flow of water through hydraulic motors, drives and absorption of rotating pipe, the hydraulic cylinder piston suction pipe and drive for axial movement, absorb the components and by axial movement and the rotary motion of the entire mesh with inner surface completely clean. The cleaning process will continue for several seconds drain valve in cleaning the end closed, the increase of the pressure of hydraulic cylinder piston will return to its original position, the nets type filter began to prepare for the next flush cycle in the cleaning process, filter normal filter work uninterrupted.
