Stainless Steel Filter Works
Nov 09, 2018

The filter core adopts a high-strength wedge-shaped filter screen to automatically clean the filter element by differential pressure control and timing control. When the impurities in the filter accumulate on the surface of the filter element and the differential pressure between the inlet and outlet increases to a set value, or the timer reaches a preset time, the electric control box sends a signal to drive the backwashing mechanism. When the backwashing suction port is directly opposite to the filter inlet, the drain valve is opened. 


At this time, the system is drained, and a negative pressure zone is formed on the inside of the suction cup and the filter core, which is lower than the water pressure outside the filter, forcing part of the circulating water from the outside of the filter. Inside the filter element, the foreign particles adsorbed on the inner wall of the filter element flow into the tray with water and are discharged from the drain valve. The specially designed filter screen creates a jetting effect inside the filter element and any impurities will be washed away from the smooth inner wall. When the pressure difference between the inlet and outlet of the filter returns to normal or the timer setting time is over, the material continues to flow during the whole process, and the backwash consumes less water, which realizes continuous and automated production. Due to the low concentration of production in the industry, the high-end product phase The supporting research and development capabilities are low, and the manufacturing technology level of the stainless steel filter industry is still low. The trade deficit between import and export continues to expand. 


The next few years will be a high-speed shock period for the stainless steel filter industry. The direct consequence of this high-speed shock is the expansion of the polarization in the brand camp. It is expected that there will be absolutely no such enterprises that can truly survive in the market in the next few years. But this high-speed shock in the stainless steel filter industry will bring huge opportunities, and the shock will make the market more rational. The high-end localization road is unusually "frustrated." The basic parts have become a short-term constraint to the development of high-end stainless steel filter manufacturing in China. During the 12th Five-Year Plan period, the government will continue to increase the localization of high-end equipment components for stainless steel filters.
