Product Description

Introduction
The "art" of filtration utilizes many methods for separating solid particles from fluids. There is often no right or wrong method. Water quality and customer requirements usually determine the "best" method for each unique situation. Ridged screens, pleated cartridges, string wound cartridges, melt blown cartridges, woven fabrics, non woven fabrics, sintered metals, granular media, frizzy balls and membranes are just some of the types of filters available today. This plethora of filter types are often employed to do the
same thing - remove suspended solids from a stream of water. This manuscript will concentrate on only automatic self-cleaning screen filters and their properties. Aside from all the advantages of screen filtration, one of the biggest hindrances to their use is
their tendency to clog quickly and need for frequent cleaning. There are a number of automatic methods in practice to eliminate the need for labor when cleaning the permanent screens in this class of filter. However, some work better than others. This research   will discuss one type of automatic self-cleaning screen filter having a proven record with tens-of-thousands of successful installations around the world. 
  
The cleaning process
During filtration water flows though the cylindrical screen of the strainer from the inside out. Debris collected on the inner surface of the screen form a "filter cake" that causes a pressure drop across the screen. When this pressure differential reaches a preset value, it is detected by the filter control system and the self-cleaning process automatically starts.
A specially designed exhaust valve, opens and the  drive unit starts to rotate two stainless steel brushes which sweep the inner surface of the cylindrical screen. The particles trapped on the screen are dislodged by the revolving brushes and flushed out through the open exhaust valve. Service flow of filtered water is uninterrupted throughout the approximate 20 seconds cleaning process. At the end of the self-cleaning process the motor stops and the exhaust valve closes. The filter control system continues to monitor the differential pressure and when needed starts a new self-cleaning cycle.  automatic brush filters are useful mostly for heavy duty, heavy dirt load and coarse filtration applications ranging from 3500 to 200 micron.

Function
Automatic brush filter the original water filtration and automatic filter cleaning discharge function, and cleaning sewage system uninterrupted water supply. Automatic brush filter cleaning has two control modes: Automatic control and manual control.

Automatic control: Automatic control timing and pressure difference. In the filtering time timer is set on the filtration time, when the filtering time, start the sewage, discharge time from emission time timer setting. At the same time control system real time system and the pressure difference of the user set pressure difference comparison, when the system pressure reaches the set pressure, Also for cleaning sewage filter, pollution by sewage time timer. Arrive at discharge sewage time, stop washing, the system is restored to its initial state, following is the preparing for the next process.
Manual control: Will the operation panel on the automatic / manual selection switch to manual position, filter for sewage.
The user can choose according to the two control mode, specific operations, see behind the operation part.

Feature
1. Electric device of the automatic washing
2. Filtering precision is from 3500 um to 200 um
3. Simple washing way: By stainless steel brush
4. Anti— Corrosion: Phosphatization treatment, the outside steel is coated with resin; It also could be with the shell of anti— Corrosion of the seawater or the stainless steel body.
5. No cutoff for the backwashing, low water consumption: No more than 1% of the total quantity.

Scope of application:
The circulated or non-circulated cooling water system, heat exchange system, central air conditioning system and central heating system in the industries like architecture, chemistry, metallurgy, rubber, paper making, light textile, coal and foods, used to protect the cooling equipment, heat exchange device and air conditioner accordingly.
