The Roots blower used in aquaculture is a gas conveying equipment commonly used in aquaculture. Its main function is to fill the aquaculture water with air, increase the dissolved oxygen content in the water, and provide a good living environment for aquatic organisms. The following is a detailed introduction to Roots blowers used in aquaculture:
1、 Working principle
Roots blower belongs to the positive displacement fan, and its working principle is to use two blade shaped rotors to compress and transport gas through relative motion in the cylinder. When the rotor rotates, a vacuum state is formed at the intake port, and air enters the intake chamber under the action of atmospheric pressure. Subsequently, the blades of each rotor form a sealed chamber with the casing and wall panels, carrying the air from the intake chamber to the exhaust chamber. Due to the mutual meshing of the rotors in the exhaust chamber, the air between the blades is squeezed out, thereby achieving continuous gas delivery.
2、 Main features
1. Stable flow rate: Roots blower has the characteristic of forced gas transmission. When the pressure is adjusted within the allowable range, the flow rate changes very little, thus ensuring the stability of dissolved oxygen content in aquaculture water.
2. Wide pressure range: Roots blowers can provide a wide range of pressure options to meet the needs of different breeding scenarios.
3. Simple and compact structure: Roots blowers have a relatively simple structure, are easy to manufacture, and have a small size, making them easy to install and use on breeding sites.
4. Easy maintenance: The main components of Roots blower, such as impeller and shaft, have a sturdy structure and are not easily worn, making maintenance relatively convenient.
3、 Application Fields
In aquaculture, Roots blowers are mainly used for the following purposes:
1. Pond oxygenation: By introducing air into the water through an aeration system, the dissolved oxygen content in the water is increased, leading to an increase in aquaculture density and yield.
2. Circular aquaculture: In a circular aquaculture system, Roots blowers are used to promote water circulation, maintain stable water quality, and oxygenate the water.
4、 Selection suggestions
1. According to the scale of aquaculture, different models of Roots blowers should be selected for farms of different scales. Small farms or household aquariums can use small Roots blowers, while large farms require larger power equipment.
2. Consider oxygenation efficiency: When choosing a Roots blower, it is important to pay attention to its oxygenation efficiency. The Roots blower can increase the dissolved oxygen content in the water more quickly, improving the aquaculture efficiency.
3. Pay attention to noise control: Although modern Roots blowers have done relatively well in noise reduction, it is still necessary to pay attention to the noise level when purchasing and choose products with good noise control to reduce the impact on the surrounding environment.
4. Consider maintenance: Regular maintenance is crucial to ensure the normal operation of Roots blowers. When making a purchase, it is important to understand the maintenance requirements of the equipment in order to better maintain it during use.
5、 Precautions for use
1. Avoid overloading operation: During use, ensure that the Paultz blower operates at rated pressure to avoid equipment damage caused by overloading.
2. Regular inspection and maintenance: Regularly check the operation status, gas delivery efficiency, and wear of components of the equipment, and promptly clean and replace damaged parts.
3. Reasonably arrange the location of equipment: In order to reduce the impact of noise on the surrounding environment, the position of Roots blowers should be arranged reasonably and corresponding noise reduction measures should be taken.
In summary, Roots blowers used in aquaculture have the characteristics of stable flow rate, wide pressure range, simple and compact structure, and have broad application prospects in aquaculture. In the selection and use process, comprehensive consideration should be given to factors such as breeding scale, oxygenation efficiency, noise control, and maintenance to ensure the normal operation of equipment and the improvement of breeding efficiency.
