How many aerators are included in the 7.5 motor of an 80 Roots blower? Calculation method and selection suggestions
introduction
In aquaculture, an 80 Roots blower is often used in conjunction with an aerator to provide sufficient oxygen to the aquaculture pond. This article will provide a detailed introduction to the calculation method of how many oxygenation disks can be driven by the 7.5 motor of an 80 Roots blower, and provide selection suggestions.
Working principle of oxygenation disc
The aerator releases bubbles through micropores, dissolving oxygen into water. The oxygen transfer efficiency is related to factors such as bubble size, water depth, and water quality.
Performance parameters of 7.5 motor for 80 Roots blower
1. * * Airflow * *: 80 Roots blower. The airflow of the 7.5 motor is usually between 5-10 cubic meters per minute, and the specific value needs to refer to the equipment nameplate or the data provided by the manufacturer.
2. Wind pressure: The wind pressure range is generally 9.8-49 kPa, suitable for different water depths and pipeline lengths.
method of calculation
1. * * Single disk gas consumption * *: The gas consumption of each aerator disk is usually between 0.5-1 cubic meter/hour, and the specific value needs to refer to the specifications of the aerator disk.
2. * * Total gas consumption * *: Calculate the total gas consumption based on the number of oxygenation disks and the gas consumption per disk.
3. * * Matching fan air volume * *: Ensure that the air volume of the 80 Roots blower can meet the total air consumption requirements.
Example Calculation
Assuming that the air consumption of each aerator is 0.8 cubic meters per hour and the air volume of the 80 Roots blower is 8 cubic meters per minute (i.e. 480 cubic meters per hour), then:
-The number of oxygenation disks=fan air volume/single disk air consumption=480/0.8=600.
-In practical use, pipeline losses and oxygenation efficiency need to be considered, and it is recommended to reduce the quantity appropriately.
Selection suggestions
1. * * According to the area of the breeding pool * *: 1-2 aerators are usually required per square meter of the breeding pool.
2. * * Consider fan margin * *: When selecting a fan, it is recommended to leave a margin of 20-30 to cope with unexpected demands.
3. * * Matching pipeline design * *: Reasonably design pipeline layout, reduce pressure loss, and improve oxygenation efficiency.
conclusion
Through scientific calculation and selection, the 80 Roots blower 7.5 motor can drive a large number of aerators to meet the oxygen demand of aquaculture. Reasonably matching the number of equipment and aerators can improve breeding efficiency and reduce operating costs.
