Introduction

Brush type self-cleaning filter lefilter

Brush type self-cleaning filter

The optional range of filtering accuracy is 50 to 5000 microns. The filter has large filtration area and high pollution absorption ability. Users can customize the filter according to the actual working conditions. The cleaning method is simple, and the cleaning cycle monitoring can realize automatic cleaning and sewage. All parameters of the automatic filter control system can be adjusted. The filter is equipped with motor overload protection function, which can effectively protect the motor.

Application Agricultural irrigation, raw water treatment, industrial circulating water filtering, cooling water treatment, paper industry, plastic industry, power industry and other industries.
Filter medium Suspended solids, particulate matter, water quality dirt, bacteria and algae, corrosion, etc

Features

The filter adopts mechatronics design. Automatic self-cleaning filter is composed of driving mechanism, control pipeline (including differential pressure switch), main component, filter component, cleaning mechanism, connecting flange and other main components. The control part of the filter is composed of an electronic controller, a control line and a blowdown valve, which is used to realize the automatic cleaning and blowdown process. The control pipeline is composed of differential pressure switch, pipe joint, brass pipe and other accessories. Conventional filter is equipped with a stainless steel brush, but you can also choose other types of brushes according to different usage conditions (water temperature, water quality).
1) The filter precision is 100 micron by default, and can be selected from 50 to 5000 micron. The filtering area is large and the pollution absorption is high. Users can customize the filter according to the actual working conditions.
2) The cleaning method is simple, and the cleaning cycle monitoring can realize automatic cleaning and sewage. All parameters of the automatic filter control system can be adjusted.
3) The filter is equipped with motor overload protection function, which can effectively protect the motor.
4) It has the characteristics of uninterrupted water supply and no bypass during cleaning and sewage discharge. Besides, the cleaning time is short and the sewage discharge consumption is less than 3% of the total flow.
5) Strong maintainability, easy installation and disassembly. The connection flange has strong versatility.

Working principle

Automatic self-cleaning filter has the function of filtering the raw water and cleaning the filter element automatically, and the system will provide uninterrupted water supply during self-cleaning and sewage draining process.
There are two kinds of control mode: automatic control and manual control.
Automatic control: Automatic control has two ways of timing and differential pressure.
Timing control: Set the filtration time on the filtration timer. When the filtration time is up, the sewage discharge is started, and the sewage discharge time is set by the sewage discharge timer.
Differential pressure control: At the same time, the control system will compare the pressure difference of the system with the pressure difference set by the user in real time. When the pressure difference of the system reaches the setting value, the filter will also clean the the filter element and discharge sewage automatically, and the sewage discharge time is set by the sewage discharge timer. When the sewage discharge time is up, the filter will stop self-cleaning process and restore the system to its initial state to prepare for the next filtration process.
Manual control: Turn the manual/automatic selector switch on the operation panel to the manual position to discharge sewage.
