How to select the oxidation fan (Roots fan) according to the manufacturer's analysis?

How to select the oxidation fan (Roots fan) according to the manufacturer's analysis? When selecting oxidation roots blower, several factors need to be considered to ensure that the selection is suitable for specific application needs. The following are the key steps for model selection:

1. Determine the medium to be conveyed: first, it is necessary to specify the type of medium to be conveyed. For example, if air is conveyed, ordinary materials can be selected; If flammable gas or corrosive gas is transported, cast iron or stainless steel fan shall be selected.

2. Consider the working environment and application requirements: determine the type and parameters of the fan according to the working environment (such as indoor or outdoor) and transmission requirements (positive pressure pneumatic transmission or negative pressure vacuum, etc.). For example, positive pressure pneumatic conveying usually requires higher air pressure and air volume, while negative pressure vacuum may require lower air pressure.

3. Calculation of air volume and air pressure: calculate the required air volume and air pressure, as well as motor power and other parameters according to the use and working conditions. Different applications have different requirements for fan parameters.

4. Other factors: model selection is based on dissolved oxygen, tank volume, number of aerators and aeration mode. These factors may affect the selection and performance of fans.

To sum up, when selecting oxidation roots blower, factors such as conveying medium, working environment, application demand, air volume and pressure, dissolved oxygen, tank volume, number of aerators and aeration mode need to be comprehensively considered to ensure that the fan can meet specific application requirements.
