The aeration and self settling ventilation hose for aquaculture ponds is a commonly used component of aeration equipment in aquaculture. The following is a detailed introduction to it:
1、 Function
The main function of the oxygen increasing self settling ventilation hose is to transport oxygen from the air through the pipeline to the bottom of the fish pond and disperse it into the water in the form of microbubbles. These microbubbles will fully dissolve oxygen into the water during their ascent, thereby increasing the dissolved oxygen level in the fish pond and providing a better living environment for aquatic organisms, promoting their growth and reproduction. At the same time, the oxygenation process can accelerate water flow, help improve water quality, and reduce the accumulation of harmful substances.
2、 Material and Characteristics
Oxygen increasing self sinking ventilation hoses are usually made of corrosion-resistant and pressure resistant materials such as PVC or PE to ensure their long-term reliability and performance. These hoses have the flexibility to adapt to the complex terrain at the bottom of the fish pond, and their self sinking design allows them to stably suspend in the water without the need for additional weights. In addition, the smooth inner wall of the hose can reduce the resistance of oxygen during transportation and improve oxygenation efficiency.
3、 Installation method
The installation method of the aerator self sinking ventilation hose is usually connected to the aerator, and air is sent into the hose through a pipeline. During the installation process, the following points should be noted:
1. Pipeline layout: Pipeline layout should avoid twists and turns as much as possible to reduce resistance and pressure loss. At the same time, it is necessary to ensure that the hose can stably cover the bottom of the fish pond to achieve uniform oxygenation.
2. Connection method: The connection between the hose and the aerator, as well as other pipelines, requires the use of appropriate connectors such as hot-melt connectors, threaded connectors, etc. These connectors should have good sealing to prevent oxygen leakage.
3. Bracket setting: Adding brackets to the hose can increase its stability and stability, preventing the hose from shifting or being damaged due to water flow erosion or fish activity.
4、 Usage and maintenance
When using oxygen enriched self sinking ventilation hoses, the following points should be noted:
1. Start up time: Determine the time and period for starting up and increasing oxygen based on the pattern of dissolved oxygen in the water. Usually, in rainy weather, high temperature seasons, or when the breeding density is high, it is necessary to extend the start-up time appropriately to increase the dissolved oxygen level.
2. Monitoring dissolved oxygen: It is recommended to use professional water quality monitoring instruments to monitor the dissolved oxygen level in the pond in real time to ensure that the dissolved oxygen in the water remains within an appropriate range (such as 6-8 milligrams per liter).
3. Regular maintenance: Regularly inspect and maintain hoses, clean blockages, replace damaged parts to ensure they are unobstructed and extend their service life.
5、 Precautions
1. When choosing oxygen enriched self settling ventilation hoses, reasonable selection should be made based on factors such as the size of the fish pond, aquaculture density, and water quality conditions.
2. During installation and use, operating procedures and specifications should be strictly followed to ensure the safety of personnel and equipment.
3. Avoid exposing the hose to sunlight or high temperature environments to prevent aging or damage.
In summary, aerobic self settling ventilation hoses play an important role in increasing dissolved oxygen levels, improving water quality, and promoting the growth of aquatic organisms in aquaculture ponds. During use, attention should be paid to the details of installation, use, and maintenance to ensure its normal operation and effectiveness.
