Selection Guide for High Density Aquaculture Oxygenation Roots Fan
In high-density aquaculture, oxygenation is a key step in ensuring water quality and healthy growth of aquaculture organisms. Roots blower has become a commonly used oxygenation equipment in high-density aquaculture due to its characteristics of constant air flow, stable performance, sufficient exhaust, and high exhaust pressure. The following is a detailed selection guide to help breeders choose the appropriate Roots blower for their breeding needs.
1、 Breeding varieties and characteristics
1. Adult fish farming:
Requirement: Adult fish have high requirements for dissolved oxygen and water quality, and require a Roots blower with comprehensive functions such as oxygenation, agitation, and aeration.
Selection suggestion: Choose a Roots blower with moderate air volume and stable pressure to ensure sufficient dissolved oxygen and water mixing effect.
2. Fish fry farming:
Requirement: The fish fry pond is relatively small, requiring low water flow and agitation, but also requiring oxygenation.
Selection suggestion: Although Roots blowers are also suitable, it is also possible to consider using jet aerators with simpler structures that can generate water flow and stir water bodies. If choosing a Roots blower, one should choose a model with lower air volume and moderate pressure.
2、 Breeding area and water depth
1. Large scale, deepwater aquaculture:
Requirement: Large and deep aquaculture ponds require greater air volume and higher pressure to ensure sufficient dissolved oxygen and water mixing efficiency.
Selection suggestion: Choose Roots blowers with high air volume and pressure, such as SR50-200, and calculate the required air volume and pressure parameters based on the specific aquaculture area and water depth.
2. Small scale and shallow water aquaculture:
Requirement: Small and shallow aquaculture ponds have lower requirements for air volume and pressure.
Selection suggestion: Choose a Roots blower with moderate air volume and low pressure to save costs and meet breeding needs.
3、 Water quality conditions
1. Poor water quality:
Requirement: Aquaculture ponds with poor water quality and high material content require Roots blowers with stable performance and sufficient exhaust to increase the redox potential and dissolved oxygen content of the water.
Selection suggestion: Choose a Roots blower with capable and stable air outlet to ensure the improvement of water quality and the healthy growth of aquaculture organisms.
2. Good water quality:
Requirement: Aquaculture ponds with good water quality and low material content have lower requirements for Roots blowers.
Selection suggestion: Choose a Roots blower with moderate pressure and air volume to meet basic oxygenation needs.
4、 Number and layout of aeration plates
1. There are many aeration plates:
Requirement: A large number of aeration plates means that a larger air volume and higher pressure are required to ensure that each aeration plate can work properly.
Selection suggestion: Select the corresponding model of Roots blower based on the number and layout of aeration discs, and ensure that the power of the blower matches the model.
2. Few aeration plates:
Requirement: When the number of aeration plates is small, the demand for air volume and pressure also decreases accordingly.
Selection suggestion: Choose a smaller Roots blower to meet the basic oxygenation requirements.
5、 Other precautions
1. Wind turbine power matching: When selecting a Roots blower, it is necessary to ensure that the wind turbine power matches the wind turbine model to avoid the situation of "a small horse pulling a big car". If the power of the fan is insufficient, it will cause problems such as fan overvoltage and motor overcurrent, which will affect the aeration effect and equipment life.
2. Maintenance: Roots blowers require regular maintenance during use, including changing lubricating oil, cleaning the inside of the blower, etc. If the fan is not used for a long time, diesel or lubricant needs to be added to the rotor for protection.
3. Manufacturer selection: It is recommended to choose a manufacturer with rich experience in oxygenation for purchase and technical guidance to ensure that the selection and use of Roots blowers meet actual needs.
In summary, the selection of aerobic Roots blowers for high-density aquaculture requires comprehensive consideration of multiple factors such as aquaculture species, aquaculture area and water depth, water quality conditions, and the number of aeration plates. Through reasonable selection and use, the role of Roots blowers in aquaculture can be ensured, improving aquaculture efficiency and water production.
