Regarding water filters

The filter element adopts a high-strength wedge-shaped filter screen, which automatically cleans the filter element through pressure difference control and timing control. When impurities accumulate on the surface of the filter element, causing the pressure difference between the inlet and outlet to increase to the set value, or when the timer reaches the preset time, the electric control box sends a signal to drive the backwash mechanism. When the backwash suction cup port is aligned with the inlet of the filter element, the drain valve opens, and the system releases pressure and drains water. A negative pressure zone with a relative pressure lower than the water pressure outside the filter element appears on the inside of the suction cup and filter element, forcing some of the clean circulating water to flow from the outside of the filter element into the inside of the filter element. Impurities and particles adsorbed on the inner wall of the filter element flow into the tray with the water and are discharged from the drain valve.
The specially designed filter creates a jet 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 set time ends, the material does not stop flowing throughout the entire process, and the backwash consumes less water, achieving continuous and automated production.
After installation, the equipment is debugged by technicians to set the filtration time and cleaning conversion time. The water to be treated enters the body through the inlet, and the filter starts to work normally. When the preset cleaning time is reached, the electronic controller sends signals to the hydraulic control valve and the driving motor, triggering the following actions: the motor drives the brush to rotate, cleaning the filter element, and at the same time, the control valve opens for sewage discharge. The entire cleaning process only lasts for a few tens of seconds. When the cleaning is completed, the control valve is closed, the motor stops rotating, the system returns to its initial state, and the next filtration process begins.
