The water of differential pressure fully automatic filter enters from the entrance, passes through the coarse screen first to filter out the larger particles of impurities, and then reaches the fine screen. In the filtering process, the fine screen gradually accumulates the dirt and impurities in the water, forming a filtering impurity layer, and as the impurity layer accumulates on the inner side of the fine screen, a pressure difference is formed on the inner and outer sides of the fine screen.

When the differential pressure of differential pressure automatic filter reaches the preset value, the automatic cleaning process will start. During this period, the clean water supply will flow continuously, the cleaning valve will open, and the water pressure in the cleaning chamber and the suction dirt collector will drop drastically, and through the pressure difference between the filter cartridge and the suction pipe, a suction force will be generated between the suction pipe and the cleaning chamber through the suction nozzle, forming a suction process. At the same time, the electric motor drives the suction tube to do spiral movement along the axial direction. The combination of axial movement and rotating movement of differential pressure automatic filter dirt suction will clean the whole inner surface of the screen. The whole rinsing process takes only tens of seconds. The discharge valve closes at the end of cleaning. The filter starts to prepare for the next rinsing cycle.

Differential pressure automatic filter cleaning method: the filter backwashing method uses motor-driven, suction nozzle sucking, reducer motor drives the suction device and suction nozzle rotation, suction nozzle sucking the inner wall of the fine screen to complete the suction.

Differential pressure automatic filter product functions and features.

1、Product function: The differential pressure automatic filter has the function of filtering the raw water and automatically cleaning and discharging the filter element, and the system has uninterrupted water supply when cleaning and discharging. There are two ways to clean the differential pressure fully automatic filter: automatic control and manual control. Automatic control: There are two ways of automatic control: timing and differential pressure. Set the filtering time on the filtering time timer, when the filtering time is up, start the discharge, and the discharge time is set by the discharge time timer; at the same time, the control system compares the system pressure difference with the pressure difference set by the user in real time, and when the system pressure difference reaches the set pressure difference, the filter is also cleaned and discharged, and the discharge time is set by the discharge time timer. When the discharge time is up, the cleaning will stop and the system will return to its initial state, ready for the next filtration process. Manual control: Manual control is the means of system debugging, system working status detection, system troubleshooting and cleaning and discharging on demand. Manual control: The "manual/automatic" selector switch on the operation panel is set to the manual position to perform manual drainage and manual cleaning respectively. Users can choose two control methods according to their needs, and the specific operation is shown in the operation section later.

Differential pressure automatic filter product features

1） The default filtration accuracy is 100 microns, and it can be selected from 100 to 3000 microns, with large filtration area and high dirt holding capacity, which can be customized by users according to actual working conditions.

2）The cleaning method is simple, and the cleaning cycle is electronically monitored, which can realize automatic cleaning and discharging. All parameters in the differential pressure automatic filter control system can be adjusted.

(3) Differential pressure automatic filter is equipped with motor overload protection, which can effectively protect the motor.

4）The differential pressure automatic filter has the characteristics of uninterrupted water supply and no bypass when cleaning and discharging, and the cleaning time is short and the water consumption of discharging is small, not more than 1% of the total flow.

5）Differential pressure automatic filter modular structure, strong maintainability, easy to install and disassemble.

6）The connection between differential pressure automatic filter and user pipeline is flange connection, and the flange adopts national standard flange, which is universal.
