Operation principle
Filtering: unfiltered fluid into automatic backwash filters, from internal flow filter filter to filter the external, filtering, from inside to outside the pollution particles in the liquid is intercepted inside the smooth filter, as more and more pollution particles were intercepted, filter pollution side and clean side between the differential pressure will be more and more big, when the differential pressure increases to filter the default transmission differential pressure, began to automatic backwash filter. Back flush: gear motors will filter at the bottom of the wash arm rotation to positive cleaning of the filter, the roots of the first - filter inside and discharge pipes connected by flushing the arm; Backflush valve open; On the outside of the filter element creates pressure drop between the drainage pipe and a small amount of the filtered clean liquid, from inside the filter outside rapid flow filter blocked inside the filter pollution Yong grain was raced along the flush arm and discharge pipes file filter; The backwashing time of each filter element ends and the backwashing door closes. Each filter element is cleaned in turn and is considered to be the end of a backwash cycle.
Application industry
Industrial circulating water filtering: the water quality has certain requirements of equipment such as: cooling tower, rolling mill, continuous casting machine, polishing machine, electric ion exchanger, sprayer, heat exchangers and other water supply and drainage pipe used on the road, can filter out the impurity in water, prevent the blocked parts
Water treatment: it can filter surface rivers, lakes, sea water, reservoir water, well water and groundwater to remove sand, bacteria, algae, organic matter, etc. Used for water filtration by boiler wet dust removal; Used for seawater filtration;
Cooling water treatment: water filtration in cooling tower, supplementary water system, air conditioning system and dc system to reduce the production of precipitation in the heat exchanger and maintain its cooling effect; Power plant to steam turbine cooling;
Chemical, petrochemical, food and pharmaceutical industries: liquid, industrial waste water, emulsion regeneration and waste oil filtration treatment continuous casting water, blast furnace water system, high pressure water phosphorus removal system for hot rolling;
S papermaking industry: widely used in water, equipment seal water, water spray, dry cleaning and cooling water circulating water filtration, protection of nozzle in papermaking equipment, mesh cloth, vacuum pump, etc., to reduce congestion caused by wear failure
