◆ working principle

The water to be treated enters the body through the inlet, and impurities in the water deposit on the stainless steel filter screen, resulting in a pressure difference. By monitoring the pressure difference changes at the inlet and outlet through a pressure difference switch, when the pressure difference reaches the set value, the electric controller sends a signal to the drain valve and drive the motor, triggering the following actions: the motor drives the cleaning component to rotate to clean the filter element, and the control valve opens to drain. The entire cleaning process only lasts for tens of seconds. When the cleaning is completed, the control valve is closed, the motor stops rotating, and the system returns to its initial state, Start the next filtering process. After the installation of the equipment, technicians will debug it according to the on-site water quality, set the filtration time and cleaning conversion time. The water to be treated will enter the body from the inlet, and the filter will start working normally. When the preset cleaning time is reached, the electric controller sends signals to the hydraulic control valve and driving motor, triggering the following actions: the electric motor drives the cleaning component to rotate, cleaning the filter element, and the control valve opens to drain. The entire cleaning process only lasts for 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 filtering process begins.

◆introduce

The fully automatic self-cleaning filter is a precision equipment that directly intercepts impurities in water through a filter screen to purify water quality and protect the normal operation of other equipment in the system. Water enters the self-cleaning filter body from the water inlet. Due to intelligent (PLC, PAC) design, the system can automatically identify the degree of impurity deposition and signal the sewage valve to automatically discharge. The fully automatic self-cleaning filter overcomes the many shortcomings of traditional filtering products, such as low pollution capacity, easy blockage by dirt, the need to disassemble and clean the filtering part, and the inability to monitor the filter status. It has the function of filtering the raw water and automatically cleaning and discharging the filter element. The system also provides uninterrupted water supply during cleaning and discharging, which can monitor the working status of the filter with a high degree of automation. Covering various filtration accuracy requirements from 10um to 3000um, we provide customers with circulating water filtration equipment.
