Automatic Brushaway Water Filters for Heat Exchange System (ISO9001: 2008, SGS)

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.

Feature
Filter precision from 100um to 3500um,big filter area,high sewage carrying capacity,customized product.
Simple turn-of-a-handle cleaning of the filter screen,adjust the parameter of the automatic cleaning system.Automatic cleaning.
Has motor overload protection, which can effectively protect the motor.
Eliminates the need for turning off the water and extracting the filter screen for rinsing.No interruption of the process water flow during cleaning,Low pressure loss:less than 1%.
Easy to maintenance,installation and disassemble.
Flange connections to the user's pipeline, national standard flange, versatility.

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.
