The Working Principle Of The Water Filter

Manual working process: after the water filter is connected to the pipeline system, the water enters the water filter from the lower water inlet, and the water after filtering the debris flows out from the water outlet, when the impurities in the water pass through the mesh core, because the volume is larger than the mesh core hole, and the slit is trapped on the mesh core, when it accumulates to a certain amount, that is, the water inlet and the outlet have a certain pressure difference. When the water pressure difference between the inlet pressure gauge and the outlet pressure gauge of the filter screen increases to the specified value (the accuracy diameter of the filter screen is different, the pressure difference is different, generally 0.15Mpa), open the sewage valve and put it into work, the water flow backflushes the impurities and dirt attached to the inner wall of the mesh core, discharges the attached matter out of the strainer, and closes the sewage valve when the pressure difference between inside and outside returns to normal, so as to complete the filtration and sewage work process.
If the user selects an automatic water filter, differential pressure blowdown and regular sewage can be selected.
1. Differential pressure discharge: when impurities accumulate to a certain amount, the differential pressure signal between the cooling water inlet and outlet pipes is used to backwash the blowdown, the differential pressure transmitter signal is connected to the control signal, the control mechanism opens the electric sewage valve, the electric reducer will run at a speed of 3-6 revolutions per minute, and the water flow backwashes the impurity dirt attached to the inner wall of the mesh core.
It is discharged into the cooling water outlet pipe through the sewage line and the sewage valve.
2. If necessary, the user can set the sewage discharge time, set the cleaning and discharging time within 0-9999 hours, let the electric reducer reverse to open the sewage valve, and reverse the backwash sewage discharge in turn.
3. According to the needs and possibilities, customers can manually open the sewage button to control and inspect the use of the system operation mode.
To order a rotary backwash water filter, please provide the following parameters:
1. Filter medium 2. Inlet and outlet pipe interface pipe diameter 3. Filter mesh diameter 4. Flow ____t/h 5. Pressure, temperature 6. Installation requirements and braking mode
Determine the installation position and installation type of the water filter (such as: high inlet and low output, oblique insertion type, side in, medium output, etc.).
