Which is a good aeration and oxygenation blower for powder particle transportation

Aeration and oxygenation blower

The aeration high-pressure blower is a centrifugal single suction double support structure, driven by a motor or turbine through an elastic column pin coupling to drive the blower. From the rear end of the motor or turbine, the blower rotor rotates counterclockwise with the inlet and outlet facing upwards. The blower housing is made of cast iron and has advantages such as vibration reduction, noise reduction, corrosion resistance, and high temperature resistance. The spindle is made of high-quality carbon steel, and the impeller is made of ordinary low-alloy steel. If the pressure is too high, high-strength alloy steel is generally used. Bearings have both rolling and sliding functions. Rolling bearings are lubricated with lithium molybdenum disulfide based grease, while sliding bearings are lubricated with forced oil supply.

Characteristics of aeration fan:

1. It has dual functions of blowing and suction, and can be used for both suction and blowing; There is a high-pressure blower that can simultaneously use suction and blowing functions, similar to a rotary vane vacuum pump;

2. Running with little or no oil, the output air is clean;

3. Compared to centrifugal fans and medium pressure fans, their pressure is much higher, often more than ten times that of centrifugal fans. For example, there is a new high-pressure blower with an output pressure of up to 100KPA;

4. If the pump body is die cast as a whole and shockproof mounting feet are used, the requirements for the installation foundation are also very low. It can operate normally without fixing the feet, which is very convenient and saves installation costs and installation cycles;

5. Compared to other types of fans, such as Roots blowers, their operating noise is lower, and the higher the power, the more obvious it is. It will be displayed above 5.5KW;

6. Maintenance free use; Its consumable parts are only two bearings, which basically do not require maintenance within the warranty period;

Aeration blower - Aeration blowerIt is a gas source power device that uses air drainage to increase gas delivery and achieve pressurization during the process. As for aquaculture, air contains oxygen, so the amount of dissolved oxygen in water is an important factor that restricts stocking density and increases unit area yield. Not only can ensuring an appropriate amount of dissolved oxygen promote vigorous feeding, rapid growth, and increased yield of fish, but low dissolved oxygen can also hinder fish growth, causing floating heads and even suffocation and death.

Aeration blower - Aeration blowerResearch has shown that when the oxygen content in pool water is above 3mg/L, fish are more likely to live normally; When the oxygen content in the pool water is around 2mg/L, it affects the normal life of some fish; If the oxygen content in the pool water is below 1mg/L, many fish species will feel difficulty breathing and even stop feeding, resulting in floating heads. If the oxygen content in the water continues to decrease, it will cause the fish to suffocate and die. So generally, 3mg/L is used as the safe concentration of oxygen content in pool water, 2mg/L is used as the warning concentration, and 1mg/L is used as the dangerous concentration.
