Automatic stainless steel mesh type self-cleaning filter

Working principle

Automatic cleaning filterto be treated by the water inlet into the body, the impurities in the water deposited in the stainless steel wedge net, resulting in differential pressure. The pressure difference of inlet and outlet is monitored through the differential pressure switch. When the differential pressure reaches the set value, the electric control device gives a signal to the control valve and the drive motor to trigger the following actions: The motor drives the brush to rotate, cleaning the filter element, and the control valve is opened for sewage discharge. The whole cleaning process only lasts for dozens of seconds. When the cleaning is over, the control valve is closed, the motor stops rotating, the system returns to its initial state and begins to enter the next filtration process.

Working principle

Step 1：Filter

The fluid flows in from the inlet and flows out from the small gaps in the wedge cartridge in the filter. The impurity particles are easy to be intercepted. When the impurity particles accumulate on the surface of the filter screen, the pressure difference will be produced.

Step 2: Wash

When the inlet/outlet pressure difference reaches 0.5kg/cm2 (adjustable), the filter backwash system will start to work automatically. Operation by the differential pressure controller set on the body, the electric blowdown valve and a rotating stainless steel cleaning brush driven by the motor, impurities particles are easy to be brushed down by the steel brush, and then discharged by the blowdown valve, backwash time lasts about 15 seconds (adjustable), backwash does not break the flow.
