Cooler Sewage Discharge Method

1. Pressure difference sewage discharge: When impurities accumulate to a certain amount, the differential pressure signal between the cooling water inlet and outlet pipes is used to backwash and discharge sewage, that is, the electric contact pressure gauge is connected to the control signal, the control mechanism opens the electric sewage valve, and the electric reducer will run at a speed of 3-6 revolutions per minute, and discharge into the cooling water outlet pipe through the sewage pipe and the sewage valve. The cleaning and drainage takes about 5-10 minutes. When large debris appears and the filter cannot run in place, the electric device should run in the opposite direction to flush the debris.
2. If necessary, the user can set the sewage discharge time, set the cleaning and sewage discharge time within 0-99 hours, and generally set it to discharge sewage once every 12 hours. The time setting can be adjusted accordingly according to the water quality of the power plant. That is, set the time to start the electric reducer to reverse and open the sewage valve, and reverse backwash and discharge sewage in turn. Until all chambers are backwashed, the electric device stops working, the electric backwash valve and the electric sewage valve are closed, and the sewage discharge work is all over.
