What is a filter?

Filter is an indispensable device for conveying media piping, usually installed at the inlet end of other valves in the relief valve, pressure relief valve, water supply valve, and square filter. Filter has a certain size filter filter, the impurities are blocked, when the need for cleaning, as long as the removable cartridge out, after processing can be reloaded, therefore, the use of maintenance is very convenient.

Filter by the simplified, stainless steel filter, sewage part, transmission and electrical control part of the composition. When the filter is in operation, the water to be filtered is filtered by the nozzle filter.

Through the filter, through the export into the user's pipeline required for the process of recycling, the water particles are trapped in the filter inside the filter. So the continuous cycle, the particles are trapped more and more, the filtration rate is getting slower and slower, and the import of sewage is still a steady stream of access, the filter will be smaller and smaller, which in the import and export pressure When the difference is reached when the difference is reached, the differential pressure transmitter will send the electrical signal to the controller. The control system starts the drive motor to drive the shaft through the drive assembly, and the sewage outlet is opened and discharged from the sewage outlet. After cleaning, the pressure drop to a minimum, the system returns to the initial filter, the system normal operation.

The filter consists of shell, multi-element filter, backwash mechanism, and differential pressure controller and other components. The diaphragm within the shell will be divided into the upper and lower chamber, the upper cavity with a number of filter, so take full advantage of the filter space, significantly reducing the size of the filter, the lower chamber installed with anti- Flush the sucker. Work, the liquid through the inlet into the filter chamber, and through the baffle hole into the filter cavity. Blinks larger than the gap of the filter are trapped, the clear liquid through the gap to reach the upper cavity, and finally sent from the exit.

The filter uses high-strength wedge-shaped filter, through the pressure control, timing control automatic cleaning filter. When the filter impurities accumulated in the filter surface caused by the inlet and outlet pressure increases to the set value, or the timer reaches the preset time, the electric control box sends a signal to drive the backwashing mechanism. When the backwashing sucker mouth and the filter inlet is positive, the sewage valve open, then the system pressure drainage, suction cup and the inside of the filter with a relative pressure below the filter outside the pressure of the negative pressure area, forcing part of the net circulating water from the filter outside Into the inside of the filter element, adsorbed in the filter on the inner wall of the impurity particles with the water into the disk and discharged from the discharge valve. Specially designed filters make the filter inside the spray effect, any impurities will be washed away from the smooth inner wall. When the filter inlet and outlet pressure returned to normal or the timer set time is over, the whole process, the material flow, backwash water consumption, to achieve a continuous, automated production.
