The parameter performance of microporous aeration tubes for aquaculture mainly includes the following aspects:
1、 Basic specifications
1. Common specifications: such as Φ 25 * 12mm, Φ 25 * 10mm, Φ 25 * 16mm, etc. The specific specifications may vary depending on the manufacturer and product model.
2. Material: Common materials include stainless steel, rubber, plastic, etc. The choice of material has a significant impact on the service life and corrosion resistance of the aeration tube.
2、 Technical parameters
1. Ventilation rate: usually expressed in m3/m · h or m3/h, it represents the volume of gas passing through the aeration tube per unit time. The size of ventilation directly affects the aeration effect and energy consumption. Generally speaking, the larger the ventilation volume, the better the aeration effect, but the energy consumption will also increase accordingly.
2. Effective service area: Refers to the area of water that can be effectively aerated by the aeration tube, usually measured in m2/m. The larger the effective service area, the higher the aeration efficiency of the aeration pipe.
3. Oxygen utilization rate: Refers to the proportion of oxygen effectively utilized by the water body during the aeration process, usually expressed in. The higher the oxygen utilization rate, the better the aeration effect, which can effectively increase the dissolved oxygen in the water.
4. Bubble diameter: The smaller the bubble diameter, the slower the rising speed of the bubble in the water, the longer the contact time with the water, and the better the mass transfer effect. Generally speaking, the bubble diameter of microporous aeration tubes used in aquaculture is between 0.8mm and 2mm.
5. Dissolved oxygen effect: usually expressed in ppm (parts per million), it represents the amount of dissolved oxygen in the water. After using microporous aeration tubes, the dissolved oxygen content in the water will significantly increase, which is beneficial for the growth of aquaculture organisms.
6. Resistance loss: Refers to the pressure loss generated when gas passes through an aeration tube, usually measured in Pa. The smaller the resistance loss, the better the flow performance of the aeration tube and the lower the energy consumption.
3、 Performance characteristics
1. High oxygenation efficiency: Micro porous aeration tubes release small bubbles through micropores, which can significantly increase the dissolved oxygen content of water and improve the bottom layer oxygen deficiency.
2. Energy saving and consumption reducing: Compared with traditional oxygenation methods, microporous aeration tubes use less power and can significantly reduce energy consumption.
3. Improving water quality: By rolling the water and providing sufficient oxygen, microporous aeration tubes can reduce harmful substances such as ammonia nitrogen and nitrite in the water, thereby improving water quality.
4. Promoting growth: Micro porous aeration tubes can increase natural feed in water bodies, promoting the growth and reproduction of aquaculture organisms.
4、 Other parameters
1. Installation and maintenance: The installation of microporous aeration tubes should be convenient, fast, and easy to maintain. During the installation process, it is necessary to ensure that the aeration tube is kept at an appropriate distance from the bottom of the tank and avoid friction with the tank wall or other hard objects to prevent damage to the aeration tube.
2. Service life: The service life of microporous aeration tubes is affected by various factors, such as material, usage environment, maintenance status, etc. Generally speaking, choosing high-quality materials and reasonable maintenance methods can extend the service life of the exposure tube.
In summary, the parameter performance of microporous aeration tubes used in aquaculture involves multiple aspects, including basic specifications, technical parameters, performance characteristics, and other parameters. When selecting and using microporous aeration tubes, these parameter performance should be fully considered to ensure the normal operation of the aeration system and the effectiveness of aquaculture.
