Roots blower is a positive displacement blower. Its working principle mainly relies on the relative movement of two blade-shaped rotors (usually three-bladed impellers) in the cylinder to compress and transport gas. The specific process is as follows:

The working principle of Roots blower

• Impeller rotation: When the motor drives one of the impellers to rotate, the other impeller will rotate synchronously at the same speed and in the opposite direction through the action of the synchronization gear.
• Gas suction and compression: Since the gaps between the impeller and the impeller, the impeller and the casing, and the impeller and the wall panel are extremely small, a vacuum state is formed at the air inlet during the rotation of the impeller, and the air is sucked into the intake air under the action of atmospheric pressure cavity. As the impeller continues to rotate, two of the blades of each impeller, the wall panel and the casing form a sealed cavity, and the air in the intake cavity is continuously brought to the exhaust cavity by the sealed cavity formed by these two blades. And because the impellers in the exhaust chamber mesh with each other, the air between the two blades is squeezed out.
• Gas discharge: After continuous inhalation and squeezing, air is continuously transported from the air inlet to the air outlet, completing the entire gas transportation process.

root blower working principle
The working principle of Roots blower can be simply summarized into the following steps:
1.Suction stage: When the rotor rotates, the volume of the chamber gradually increases, forming a low-pressure area.This low-pressure area attracts outside air into the chamber.
2.Compression stage: As the rotor continues to rotate, the volume of the chamber gradually decreases.This process causes the air to become compressed, increasing its pressure.
3.Exhaust stage: When the volume of the chamber reaches the minimum value, the compressed air will be discharged from the chamber.At this time, the rotation of the rotor will increase the volume of the chamber again to prepare for the next round of suction.
By repeating the above steps, the Roots blower can continuously suck in, compress and discharge air.This working principle enables Roots blowers to produce high-pressure, high-flow airflow.

How to choose a Roots blower suitable for aquaculture?
Several factors need to be considered when choosing a Roots blower suitable for aquaculture, including the size of the farm, the amount of water that needs to be treated, the required ventilation effect, and the environmental characteristics of the place of use, etc. Here are some key steps and considerations:
‌Determine the scale of the farm and the amount of water that needs to be treated‌: Determine the required fan air volume based on the number and area of ​​fish ponds and the size of the space that needs ventilation. This helps in selecting the appropriate fan model and size.
‌Consider the oxygen demand of the breeding environment and fish‌: Different breeding environments and fish have different demands for dissolved oxygen, so it is necessary to adjust the bubble intensity and working intensity of the Roots blower according to the actual situation to ensure that the appropriate amount of oxygen is obtained in the water body of oxygen supply.
Choose the appropriate installation location‌: The Roots blower should be installed close to the water body to reduce the length and resistance of the delivery pipe and ensure that the air flow can be effectively transferred to the water. At the same time, you should stay away from the production area and choose a well-ventilated place to ensure good heat dissipation and low noise.
‌Match appropriate delivery pipes‌: Use pipes of appropriate diameter to connect the Roots blower and the breeding pond to reduce the resistance loss of the air flow. Make sure the ducts are well sealed to avoid airflow leaks.
‌Air filtration‌: The air sucked by the Roots blower needs to be purified by a filter to reduce wear on the cylinder and bearings. Generally, an air filter is installed in the front of the Roots blower, using filter materials such as filter sponge and desiccant.
‌Regular inspection and maintenance‌: During use, it is necessary to regularly check whether the various components of the Roots blower are working properly, such as whether the bearing temperature is too high, whether the lubricating oil is sufficient, etc. Regularly clean and maintain the Roots blower, replace lubricating oil and filter materials, etc. to keep the equipment in good condition.
‌Professional guidance and experience‌: It is recommended that users choose manufacturers with rich experience in oxygenation to provide technical guidance to ensure the correct selection and use of roots blower for aquaculture, so as to achieve the best oxygenation effect and economic benefits.

Advantages of Roots Blower in Breeding Industry
‌The advantages of Roots blowers in the breeding industry are mainly reflected in efficient oxygenation, energy saving and environmental protection, easy maintenance, safety and reliability, and wide application range. ‌

This is crucial for organisms in aquaculture, as adequate oxygen is necessary for them to breathe and grow properly. Adequate oxygen can promote the growth and survival rate of aquatic organisms, while also helping to reduce diseases and deaths caused by hypoxia, thereby improving breeding efficiency.
Energy saving and environmental protection‌: Roots blowers use volumetric compression technology, which is more energy-saving than other types of blowers, and can significantly reduce energy consumption and increase production capacity. In addition, the Roots blower has low noise and vibration during operation, is suitable for indoor use, and will not affect the aquaculture environment.
‌Easy maintenance‌: Roots blowers do not require oil changes or lubrication, so maintenance costs are low, and cleaning and repair are relatively simple. This design reduces mechanical wear or component damage, making the service life of Roots blowers much longer than other types of blowers.
Safe and reliable: The Roots blower has low noise and vibration during operation and will not cause any pollution to the water area. Other oxygenation methods work in water, which is prone to leakage and has potential harm to the human body and shrimps. The Roots blower adopts a double vortex fluid design, which is oil-free and has no friction points, so there is almost no mechanical wear or component damage, so it has a long service life, is safe and reliable.
‌Wide range of applications‌: Roots blowers are widely used not only in the aquaculture industry, but also in the flour industry, pesticide chemical industry, and mining industry. They have a wide range of uses and can increase the oxygen content in water and improve water quality through aeration. , thereby improving the survival rate and productivity of aquatic products‌.
In summary, the application of Roots blowers in the breeding industry not only improves breeding efficiency and reduces operating costs, but also improves the quality and safety of breeding products. It is an indispensable equipment in the breeding industry.

Which blower is suitable for aquaculture?
‌Blower types suitable for aquaculture include Roots blowers, high-pressure blowers, and magnetic levitation blowers.
Roots blowers‌ are widely used in aquaculture because of their scientific and reasonable design, stable operation, long-term operation, ability to transport a small amount of granular media, simple structure, low noise, strong adaptability and high reliability. Roots blower for aquaculture are suitable for situations requiring higher gas pressure and large flow rates, such as oxygenation and sewage treatment in aquaculture. Although the Roots blower has some shortcomings, such as difficulty in processing and inspection, and performance degradation under high vacuum conditions, its advantages make it a commonly used equipment in aquaculture.
High-pressure fans‌, such as high-pressure vortex air pumps, are suitable for oxygenation of aquaculture fish ponds and sewage aeration. They have the advantages of large air volume, high efficiency, energy saving, low noise and long life. They are suitable for use in large-scale aquaculture industries to increase dissolved oxygen in water. content, plays an important role in purifying water quality‌.
‌Magnetic levitation blower‌With its advantages of large air volume, high efficiency, energy saving, low noise and long life, it is suitable for large-scale aquaculture industry. In addition to increasing the content of dissolved oxygen in the water, it can also accelerate the oxidation and decomposition of certain harmful substances in the water, which plays an important role in purifying water quality. The magnetic levitation blower is one of the indispensable equipment in the shrimp farming industry‌.
