Principle
The inside of the filter casing is mainly composed of a coarse filter mesh, a fine filter mesh, a suction pipe, a stainless steel brush or a stainless steel nozzle, a sealing ring, an anti-corrosion coating, a rotating shaft and the like.
After the equipment is installed, the technician will debug and set the filtration time and cleaning conversion time, and the filter will start working normally. The water to be treated by the filter enters the body through the water inlet, and impurities in the water are deposited on the stainless steel filter screen, thereby generating a pressure difference. The differential pressure switch monitors the pressure difference between the inlet and outlet. When the pressure difference reaches the set value, the electric controller sends the hydraulic control valve and drives the motor signal, triggering the following actions: the motor drives the brush to rotate, the filter element is cleaned, and the control valve is opened. Sewage, the entire cleaning process only lasts for tens of seconds, the cleaning is over, the control valve is closed, the motor stops rotating, the system returns to its initial state, and the next filtration process begins.
