How to choose an aerator?

Selection of aerator: usually, when the water depth is 1 m, the pressure of high-pressure fan needs 10kpa, but when it reaches the limit, it can only be exposed to the water depth1m. According to the actual selection, at the water depth of 1 m, the pressure of high-pressure fan should be 18 kPa (including pipeline loss) to ensure normal operation for 24 hours.

To learn how to convert the gas output of aeration tray, generally choose 80 flat tray nano aeration tray, and the gas output of an 80 flat tray aeration tray is 2.3m? /h, when we are in normal use, we should follow an 80-flat aeration tray and press 3m for one hour to remove the pipeline loss. The calculation of air output is based on. Generally, six aeration trays should be put in one mu of land for breeding. If the breeding density is high, put more.

For example, the customer's area is 10 mu, and the water depth is 1.3 meters. According to the above calculation, the fan oxygen pump with high-pressure fan pressure above 20kpa is selected, and the air volume is not less than 180m? /h oxygen pump. When 3kw double impeller high pressure fan is selected, the air volume of RB-72S-2 oxygen pump is 320m? /h pressure: 26kpa, this can be brought up (according to the actual water depth area and installation method).
