Sl-type Water Filters

Specifications

1, Function and Uses

SL-type water filters are widely used in metallurgy, chemical industry, petroleum, paper making, medicine, food, mining, electricity, urban water supply area. Such as industrial waste water, recycled water filtration, emulsion regeneration, oil filter processing, metallurgical industry, continuous casting water systems, blast furnace water systems, hot-rolled high-pressure water descaling system. Is an advanced, efficient and easy to operate automatic filter.

2, equipment, structure and working principle of

SL-type water filters from the shell, multi-filter, anti-washing agencies, electric control box, reducer, electric valves and differential pressure controller, such as components. Diaphragm within the shell of its lumen is divided into upper and lower two cavity, the cavity is equipped with multiple filter core, so that full advantage of the filtering space, significantly reduced the size of filter, installed under the cavity backwash sucker. Work, the turbid liquid filters through the entrance into the next chamber, then through the partition hole into the cavity filter. Outweigh the impurity filter gaps are retained, the net fluid through the gap to reach the cavity, finally sent from the exit.

The filter cartridge with high-intensity Johnson wedge-shaped filters, through the pressure control, timing control self-cleaning filter. When the filter impurities accumulate in the filter surface, causing increased pressure to set the value of imports and exports, or timer to preset time, the electrical control box signals to drive backwashing body. When the anti-smoking Handicap and the filter washing being imported, the sewage valve is opened, this time the system pressure relief drainage, suction and the filter inside of the emergence of a relative pressure lower than the pressure of negative pressure outside the filter area, forcing part of the net circulating water from the filter into the filter outside of the inside wall on the adsorption of impurities in the filter particles flowing into the suction valve within the discharge from the sewage. Johnson made a specially designed filter net effect of internally generated spray, any impurities will be washed away from the smooth inner wall. When the pressure returned to normal import and export filters, or timer setting time after the motor stops, the electric sewage valve closed. Throughout the process, the material constant flow of backwash water consumption to achieve a continuous, automated production.

3, this machine features
