Introduction to the selection method of aerobic Roots blower for aquaculture
The selection method of aerobic Roots blowers for aquaculture is mainly based on multiple factors such as aquaculture species, aquaculture characteristics, aquaculture area and water depth, water quality conditions, and the number of aeration plates. The following is a detailed introduction to the selection method:
1、 Select based on the breed and characteristics of aquaculture
Different oxygenation equipment is suitable for different breeding varieties and characteristics. Roots blower has the characteristics of constant wind volume, stable performance, sufficient exhaust, high exhaust pressure, etc., and is suitable for various scales of aquaculture ponds. But the specific model selection still needs to consider the following factors:
1. For adult fish aquaculture ponds, Roots blowers with comprehensive functions such as oxygenation, agitation, and aeration can be selected to meet the needs of adult fish for dissolved oxygen and water quality.
2. For fish fry ponds, 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 the water.
2、 Select based on the breeding area and water depth
The breeding area and water depth are important factors to consider when choosing oxygenation equipment. Roots blowers are suitable for aquaculture ponds of different sizes, but the specific model selection needs to be determined based on the aquaculture area and water depth:
1. For large and deep aquaculture ponds, it is necessary to choose Roots blowers with high air volume and pressure to ensure sufficient dissolved oxygen and water mixing effect.
2. For small and shallow aquaculture ponds, Roots blowers with moderate air volume and low pressure can be selected to save costs and meet aquaculture needs.
3、 Select based on water quality conditions
Water quality conditions are also one of the important considerations when choosing oxygenation equipment. Roots blowers are suitable for aquaculture ponds with various water quality conditions, but the specific model selection also needs to consider the following factors:
1. For aquaculture ponds with poor water quality and high material content, it is necessary to choose Roots blowers with stable performance and sufficient exhaust to increase the oxidation-reduction potential and dissolved oxygen content of the water and promote the improvement of water quality.
2. For aquaculture ponds with good water quality and low material content, Roots blowers with moderate pressure and air volume can be selected to meet basic oxygenation needs.
4、 Select based on the number of aeration discs
The number of aeration plates is also one of the important factors affecting the selection of Roots blowers. There are many aeration plates and a large number of models are required; The number of aeration plates is small, so the required model is small. Therefore, when choosing a Roots blower, it is necessary to determine the model and quantity of the blower based on the number of aeration plates.
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.
In summary, the selection method of aerobic Roots blowers for aquaculture needs to consider multiple factors comprehensively. Through reasonable selection, the role of Roots blowers in aquaculture can be ensured, improving aquaculture efficiency and water production.
