1. Close the outlet valve of the dissolved air pump and stop the dissolved air pump.
2. Open the purification air valve, make the water in the shallow air float roll for 2 minutes, open the purification air valve to 5 silk threads.
3. Turn on the dissolved air pump, slowly open the outlet valve to 45°, and then observe whether the pressure gauge of the dissolved air tank is between 0.4-0.5Mpa. If the pressure is reached, the dissolved air pump is working normally. If the pressure is not reached, it needs to be opened again Dissolved air pump.
4. After the dissolved air pump is turned on, observe the ventilation status. If the aeration volume is large, continue to open the outlet of the large dissolved air pump to the fully open or large ventilation valve, or the large air valve is fully open or the large ventilation valve.
5. Because both the pressure reducer and the flow meter are broken, the adjustment of the valves on both sides of the purification air pipe is the same.
6. The inlet valve in the dissolved air water tank is fully opened to 90°.
7. Usually, the two side valves of the purification air valve are opened with two silk threads, the outlet valve of the dissolved air pump is fully opened, and the water inlet valve of the dissolved air tank is fully opened for a long time.
8. When the aeration of the same shallow air flotation aeration pipe is different, the valve of the aeration pipe can be adjusted at any time. Open half a valve near the mouth of the ventilation tank, and open it to 3/4 in the middle. The farther it is, the larger it is, and it can be adjusted at any time.
