How to realize aeration and how to select a three leaf Roots blower?

How to realize aeration and how to select a three leaf Roots blower? The principle of the three blade Roots blower is simply that the impeller rotates and extrudes air outward. The clearance between the impeller and the casing is very small (only a few wires), so the air pressure is very high, which can reach 78.4KPA (equivalent to supporting the height of 8m water column) or even higher. The faster the speed is, the larger the air volume is.

In the sewage treatment project, the model selection should be done according to the parameters such as the treated water volume and the pool depth (you can also give me the data to help you calculate it).

For different customers, I usually choose different manufacturers. The best one for foreign enterprises is imported from Germany. The price of that small pump accounts for more than half of the total cost of the whole system. Party A has no choice but to "not seek the best, but seek the most expensive".

For domestic enterprises, Changfeng, Chuanyuan and Xinqianshun are generally used; for large customers with Chinese characters, Changfeng is usually used; for those with Xinqianshun and Chuanyuan, it is cheap and affordable.

There are two tricks for sewage treatment aeration, one is to select the parameters, the other is to select the fan. A few years ago, when we first explored the industry, there were many lessons. The parameters must be carefully calculated, and more consideration should be given to the loss. The fan must be tested. Hope to help you.
