Difference between Roots blower and impeller aerator
There are significant differences between Roots blower and impeller aerator in multiple aspects. The following is a specific comparative analysis:
1、 Definition and purpose
1. Roots blower:
Roots blower is a type of positive displacement blower, consisting of five main parts: casing, wall panel, impeller, oil tank, and muffler.
Mainly used in aquaculture oxygenation, sewage treatment aeration, cement transportation and other fields, suitable for gas transportation and pressurization systems in low-pressure environments.
2. Impeller aerator:
The impeller aerator is a device specifically designed to supply oxygen to large ponds, which can increase dissolved oxygen in water, improve water quality, and enhance the economic benefits of aquaculture.
Mainly used for pond farming in aquaculture, by increasing the oxygen content in the water, the yield and quality of aquaculture can be improved.
2、 Structure and Working Principle
1. Roots blower:
Roots blower uses two blade shaped rotors to make relative motion in the cylinder to compress and transport gas.
With the characteristics of simple structure and convenient manufacturing, the three blade rotor structure makes the fan vibrate less, have low noise, and can operate continuously for a long time.
2. Impeller aerator:
The impeller aerator is mainly composed of an electric motor, a gearbox, a water surface impeller, and a floating ball.
By driving the water surface impeller to rotate with an electric motor, the water surface is stirred, and the air and liquid films are stirred to increase the contact area between gas and liquid, thereby expanding the concentration gradient of oxygen in water and improving the speed of oxygen transfer and diffusion from the air to the water.
3、 Installation method and application scenarios
1. Roots blower:
Roots blowers are usually installed on the ground and need to be fixed in a certain position to transport air to the water area that requires oxygenation through pipelines.
Due to its high oxygen density, it is suitable for high-density aquaculture and situations that require high oxygen concentrations.
2. Impeller aerator:
The impeller aerator floats on the water surface and achieves oxygenation by stirring the water with the impeller.
Mainly used for ordinary aquaculture in soil ponds, it is also suitable for water bodies, and the oxygen supply can meet the survival of waterfowl below 6 meters.
4、 Performance characteristics
1. Roots blower:
It has high gas delivery efficiency and pressure stability, and can continuously and stably provide oxygen to water bodies.
Low noise and low vibration, suitable for occasions that require low noise and low vibration.
2. Impeller aerator:
The oxygenation effect is significant, which can form an oxygen rich circle centered on the aerator in the water.
In addition to oxygenation, it also has functions such as water lifting, stirring, and exposure to harmful gases, which can improve the quality of aquaculture water.
In summary, there are significant differences between Roots blowers and impeller aerators in terms of definition and purpose, structure and working principle, installation method and application scenarios, as well as performance characteristics. The choice of device depends on the specific application scenario and requirements.
