Self Cleaning Sucking Water Filter

 

How Self Cleaning Sucking Water Filter Works

The unit consists of two stages of filtration, a coarse pre-filter and a stainless steel fine screen.
The unwanted solids accumulate on the inner surface of the fine screen, building up a filter cake, which filters out even finer particles, creating a pressure differential. Once the pressure drop reaches a preset level, a rinse cycle is activated by the factory supplied control system.
The solids are removed from the fine screen using a spot backwashing method, which aggressively sucks the dirt off the screen, similar to a vacuum cleaner, and are carried to the drain via the rinse valve. The dirt collector rotates, ensuring the entire screen is cleaned each cycle. The process takes a matter of seconds, without interruption of system flow.

Self Cleaning Sucking Water Filter Control method
Filter has differential switch and integrator. Once the pressure drop reaches a preset level, a rinse cycle is activated by the PLC controller.

Self Cleaning Sucking Water Filter Install notice

1.One check valve must be installed at filter outlet. Return pressure and back water is forbidden, in case of screen out of shape.
2.If system wok pressure over 0.8MPa, should install break valve at drain pipe to reduce impact to screen.
3.Notice motor rotating direction. Shut off power immediately once back rotating (anti-clock wise ) occurs. )
4.Installation each part according to arrow direction.
5.Sudden pressure relief at outlet pipe is forbidden. Take normal work pressure 1.3MPa for example, if suddenly open branch valve at outlet, it will occur instant huge different pressure, which damage screen.
6.Make sure filter used under correct work pressure, capacity.
7.If alarms, open by-pass valve for temporary back washing solutions.
8.Make sure control box have constant power supply. If power off, users can open by-pass valve, close in and outlet valve and control box switch.

Self Cleaning Sucking Water Filter Install requirement
1.Keep space for filter install and maintenance.
2.Drainage pipe length not longer than 20m. Avoid more turns off, keep outlet pipe parallel with ground.
Testing Water filter

1.Close inlet outlet valve before testing. Open by-pass valve. Wash dirties staying in pipes.
2.Open inlet valve gradually. Let water into filter till air comes out from filter house.
3.Check leak at joint part, check in/outlet pressure gauge. Connect power when comes to system pressure.
4.Set up drainage time based on system pressure data.
5.Open outlet valve gradually if testing is normal. Close by-pass valve back to normal filtering.
6.Observe several differential pressure changes and drainage. Finish testing if normal.

 

Notice in using Water filter

Equipment can through into operation directly, as already has trial testing. Users can adjust settings based on actual use. Change relay’s program and parameter is forbidden.

1st operation notice
Follow below steps in 1st operation:
Check drainage pipe connection. No up-inclined angle.
Check connection tighten or not.
Check control box in a dry environment.
Connect power cord, green light means normal. Make sure electrical parts is dry. Water is forbidden into control box.
