  • Product Description

    Self-cleaning filter with filtration accuracy from 50 to 5000 microns can be selected, with large filtration area and high dirt-holding capacity, which can be customized by users according to actual working conditions. The cleaning method is simple, and the cleaning cycle is monitored to realize automatic cleaning and discharging, and all parameters in the automatic filter control system can be adjusted. It is equipped with motor overload protection, which can effectively protect the motor.

    INQUIRY
    Brush type self-cleaning filter lefilter
    Applications Agricultural irrigation, raw water treatment, industrial circulating water filtration, cooling water treatment, paper industry, plastic industry, power industry and other industries
    Filtration media water body suspended matter, particulate matter, water dirt, bacteria and algae, rust, etc
  • Product Features

    It adopts electromechanical integration design. The automatic self-cleaning filter is composed of main parts such as driving mechanism, control pipeline (including differential pressure switch), main tube assembly, filter element assembly, cleaning mechanism and connecting flange. The electric controller, control pipeline and drain valve constitute the control part of the filter, which is used to realize the automatic cleaning and discharging process. The control pipeline consists of accessories such as differential pressure switches, pipe joints and brass pipes. The filter uses stainless steel brushes for conventional products, and other materials of brushes.
    (1) The filtration precision is 100 microns by default, and it can be selected from 50 to 5000 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. The parameters in the control system of automatic self-cleaning filter can be adjusted.
    (3)With motor overload protection, which can effectively protect the motor.
    (4)It 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 3% of the total flow.
    (5) Strong maintenance, easy to install and disassemble. The connection with the user's pipeline is flange connection, and the flange adopts the national standard flange, which has strong universality.

  • Working Principle

    The automatic self-cleaning 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.
    The cleaning of automatic self-cleaning filter has two control methods: automatic control and manual control.
    Automatic control: automatic control has two ways: timing and differential pressure. Set the filtering time on the filtering time timer, when the filtering time comes, 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: Turn the manual/automatic selector switch on the operation panel to the manual position, and the filter will be discharged.
