Self-cleaning filter working principle (brush type)

Apr 23, 2019

The water to be treated 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 differential pressure 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 is cleaned, and the control valve opens. For the sewage discharge, the entire cleaning process only lasts for several tens of seconds. When the cleaning is finished, the control valve is closed, the motor stops rotating, the system returns to its initial state, and the next filtration process begins. After the equipment is installed, the technician will debug and set the filtration time and cleaning conversion time. The water to be treated enters the body through the water inlet, and the filter starts to work normally. When the preset cleaning time is reached, the electric controller gives the hydraulic control valve. Driving the motor signal, triggering the following actions: the motor drives the brush to rotate, and the filter element is cleaned. At the same time, the control valve is opened for sewage discharge. The entire cleaning process only lasts for several tens of seconds. When the cleaning is finished, the control valve is closed and the motor stops rotating. The system returns to its initial state and begins the next filtration process.www.inocofiltration.com
