Automatic Back-washing Filter:

Automatic Back washing filter strainer design features
1) Suitable for the high-speed flow, low-viscosity fluid filtering. Handling capacity of a single system is up to 1600m3/h.
2) The smooth surface of the tube and the connections avoiding the dead angles, reduce pressure drop. The stainless steel wedge strainer can meet different application requirements.
3) During the backwash process, the cartridges are backwashed one-by-one.
4) The cartidge is backwashed in a safe and efficient state while other cartridges are not affected and the filtering continues.
5) The filter has less wearing parts, no consumptive materials and much lower operation and maintenance cost.
6) The coloured LCD can display the pressure of inlet and outlet, the pressure differential curve and the running situations of all facility.
7) Automatically control the time of backwash and set the differential pressure at the most reasonable value by optimal testing program.
8) The high sensitivity infrared correlation control can improve the rotation degree of backwashing arm by four times so that the time of backwash and quantity of water consumption are reduced greatly.
9) The industrial control computer with ethernet card can achieve remote observing and controlling.
10) The normal industrial process control DCS interface connect with the centralized control system.
11) USB interface can connect with external keyboard and mouse to set the parameters of system.
12) It has warning function for system overvoltage, facility fault and system fault self-diagnosis.

Automatic Swirling Self Cleaning Pipe Filter System

The automatic self cleaning filter Working principle

The automatic self cleaning filter is consisted of filter vessel, stainless steel filter screen, differential pressure switch, time-delay device and pneumatic drain valve. The liquid flows into vessel,filtered by the filter screen and flow out from outlet.So the impurities are intercepted in the filter screen. When the differential pressure reaches the pre-determined value, the filter automatically start the self-cleaning process and the impurities will go out from the drain valve.

Automatic Controlling

First,make the control system to automatic mode.

Second,when the pressure difference switch the reaches index value,the filter will start self-cleaning automatically and discharge.The time of cleaning and discharging are set by the control system.

Finally,when the time reaches to the index value, the filter will stop cleaning and continue the filtration process.

Manual Controlling

First,make the control system to manual mode.

Second, when you press the discharge button, the filter will start self-cleaning and discharge.

Finally, loosening the discharge button, the filter will stop cleaning and continue the filtration process.

 

Product Design Features

1.Suitable for the high flow rate, low-viscosity fluid filtration. The max capacity of a single system is up to 3500m3/h.

2.The filter has the ability of retrieving the instable flow rate and adjusting the time of cleaning without manual operation.

3.Filter screen is easy to be cleaned and it is not consumption part.

4.When the fitler is cleaning the filter screen, the inflow can keep working at the same time.

5.The time of cleaning process is so short that it will save raw material and power.It is very environmental.

6.Compact construct design,small floor area. Easy installation and moving flexiblly.

7.The filter has less wearing parts, no consumption parts and much lower operation and maintenance cost.

8. With extensive application filed,the filter could meet different requirements of various raw water.

9. with larger filtration area and little loss of pressure, more impurities can be filtered.

10. Every parameter can be adjusted according to the actual working condition.
