1. The backwash pressure relief sewage discharge port (DN3) is controlled by electric valve, and synchronously acts with the backwash motor, that is, the backwash motor starts, the backwash electric valve opens, and the sewage starts, the backwash motor stops at the end of the backwash, and the backwash ends; The electric valve is also closed at the same time, the end of the blowdown.
2. The sewage discharge outlet (DN4) is controlled by the manual valve. The manual blowdown valve should be opened regularly or opened during cleaning to discharge the dirt precipitated to the bottom of the main engine.
3. The pressure balancing valve and air release valve will open the exhaust gas at the beginning of the first work, and it will be closed during normal work.
4. During installation, special attention should be paid to the inlet and outlet direction and no dirt with large particle size should enter the main engine. See the instructions for details.
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.
