Automatic self-cleaning filters(Brush Type)
Product Model:SLQ

Structure and working principle
  Automatic brushaway filter is composed of the drive mechanism, the control circuit (including the pressure switch), filter components, cleaning device, connecting flanges and other major component parts.It cleans sewage by the drive motor and the electric valve automatically, the operation mode is automatic operation (option:manual operation), with timing control or pressure difference control. Its automated part is controlled by reliable PLC programmable controller.
  Water enters into the filter, the mechanical impurities are intercepted.When the impurities accumulate for a period, reaches 0.05MPa, then the differential pressure switch will send signal, while the PLC command is issued, transmission motor starts, the drain valve opens, the impurities deposited on the filter is brushed away, and drain out. The whole process is without personnel, without downtime. Besides, the device also has the function of timing and manual cleaning to ensure that the outlet water is safe under any circumstances.a

Two types of cleaning method
  Automatic control: there are two types:timing control and pressure difference. Set the filtration time on the filter timer, when it reaches the setting time, the brush will start cleaning sewage,discharge time is also set by timer; while the system pressure control system with real-time user-defined pressure compared when the system pressure reaches the set pressure difference, the filter will start cleaning sewage, sewage discharge time set by the timer.The whole system returns to its initial state, prepare for the next filtration step.
  Manual control: Press the manual button on the control panel, filters will start cleaning.

Installation Points for attention
1, The check valve must be installed to avoid back pressure or backwater phenomenon, caused by inward deformation of filter screen.
2,For the operating pressure above 0.8MPa or more, the gate valve must be installed on the sewage lines, it will reduce the pressure loss, and the impact after the drainage. (you may ask for specific advisory from suppliers)
3,Prohibit the sudden pressure relief. For example, the normal working pressure is 1.3MPa, shut down suddenly,and open the outlet piping manifold pressure relief valve, it will have a huge opening moments of pressure will cause filter damage.
4, Make sure that the filter works within the normal operating range, banned from over pressure, over flow rate.
5,When the equipment alarms, if you can not handle at once, you should immediately open the bypass valve. Otherwise, the filter can not hold pressure,and it also affect production.
6, For the filter with control box, you must ensure the continuous power supply for control box . Otherwise, it will cause filter clogging, the system hold pressure, impact production, and even cause filter damage. Re-transmission may occur because of filter clogging motor tripping the alarm. Power interruption is recommended to open the bypass valve, close the filter inlet and outlet valves and control box power switch. Filter restart when power on.

How to install
a. equipment can not be installed in the negative pressure zone.
b. noted the direction of the water flow.
c. By-pass conduit is preferably provided so that the normal operation of the filter for cleaning or failure does not affect the system;
d.Pipeline should be floated over 5m,supported by steel or concrete barrier.
e. When the filter installed with other water processor equipment, this filter should be installed before the inlet.

How to choose the suitable model
Please clarify below parameter:
1.water flow rate
2.Chemical characteristic of fluid
3.SS of fluid
4.filter precision
5.Pipe pressure
6.Working pressure
7.Direction of flow
8.drainage way

Equipment Maintenance
a. After install the brushaway filter, the pipeline should be cleaned by banging pipes,to remove the welding slag and other debris,to prevent damage caused by slag debris.Wash the filter after initial running for a week.
b. runtime system for the first time, you should first open the supply valve, until the system is filled with water, and then open the valve, in order to facilitate the removal of impurities in the pipeline, to prevent access to the coil;
c.Timely sewage drain (especially in summer) according to the system set pressure and concentration ratio.
d.In the dry state,it’s prohibit to open device for a long time. During downtime or seasonal shutdown, it should be wet protected,in avoid of pipeline corrosion.
