5 Inch Full Automatic Brush Backwashing Filter


Structure and principle
The inside structure of the automatic self-cleaning brush filter is made up of the stainless steel strainer and stainless steel wire brush and transmission part. The washing and the drainage are automatically finished by the drive motor and electrical valve. The operation way is automatic running (manual running is also Ok), It is with the double function of the pressure difference and regularly automatic drainage. The automation part takes use of the most advanced and reliable PLC in the world.
When the water flow gets through the filter, the impurity in the water is held by the strainer With the increase of the impurity accumulated on the surface of the strainer, the pressure difference reaches 0.04Mpa. The switch of the pressure difference will give out a signal while the PLC sends an instruction to start the drive motor and open the drainage valve; The impurity accumulated on the strainer will be brushed off with the rotating brush and discharged from the drainage exit. The whole process of brushing and draining require no personal operation and without machine halt. At the same time, the equipment is with the function of regular washing and draining and manual washing and draining to make sure that the water output is safe and reliable in any case.

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.
