Design of oxygenation scheme for fish pond Roots blower
##Introduction
In aquaculture, the dissolved oxygen level in fish ponds is one of the key factors affecting fish growth and health. Roots blower, as an oxygenation device, is widely used in fish pond oxygenation. This article will discuss in detail the design of the oxygenation scheme for fish pond Roots blowers, including air volume calculation, pipeline layout, equipment selection, etc.
##Analysis of Oxygen Demand for Fish Ponds
1. * * Fish pond area * *: Assuming the fish pond area is 10 acres, approximately 6667 square meters.
2. Water depth: Assuming the average water depth of the fish pond is 2 meters, the total water volume is approximately 13334 cubic meters.
3. Fish density: According to the aquaculture density, approximately 1.5 grams of dissolved oxygen are required per cubic meter of water.
4. * * Oxygen demand * *: A 10 acre fish pond requires approximately 20001 grams of dissolved oxygen per day.
##Calculation of air volume for Roots blower
1. * * Airflow Requirements * *: Select a Roots blower with appropriate airflow based on the oxygenation requirements of the fish pond. Generally speaking, a 10 acre fish pond requires a Roots blower with an air volume of 15-20 cubic meters per minute.
2. * * Power selection * *: Choose a Roots blower with a power range of 5-7.5 kilowatts based on the air volume requirements. The specific power also needs to consider factors such as the water depth of the fish pond and the density of aquaculture.
##Layout of oxygenation pipeline
1. * * Pipeline material * *: Choose corrosion-resistant and pressure resistant PVC or PE pipelines to ensure their service life and performance.
2. * * Pipe diameter * *: Choose the appropriate pipe diameter according to the air volume requirements, generally selecting pipes with a diameter of 50-75 millimeters.
3. * * Pipeline layout * *: The oxygenation pipeline should be evenly distributed in the fish pond to ensure that the air can be evenly distributed to all corners of the fish pond. It can be arranged in a circular or grid pattern.
##Equipment selection and installation
1. Selection of Roots blower: Choose Roots blowers with an air volume of 15-20 cubic meters per minute and a power of 5-7.5 kilowatts to ensure that the oxygenation needs of the fish pond are met.
2. Installation location: Roots blower should be installed in a well ventilated and easy to maintain location in the fish pond, avoiding installation in damp, dusty or high-temperature environments.
3. * * Electrical Connection * *: Connect the power supply according to the electrical drawing, ensuring correct wiring and good grounding.
##Implementation and maintenance of oxygenation plan
1. * * Debugging and Running * *: Start the Roots blower, check the operating status, adjust the air volume and pressure, and ensure the normal operation of the blower.
2. * * Regular Inspection * *: Regularly check the operating status of the Roots blower, clean the filter screen, lubricate the bearings, and ensure the normal operation of the equipment.
3. Pipeline maintenance: Regularly check the sealing and smoothness of the oxygenation pipeline to prevent air leakage and blockage that may affect the oxygenation effect.
##Conclusion
The design of the oxygenation scheme for the fish pond Roots blower requires comprehensive consideration of factors such as fish pond area, water depth, and aquaculture density, reasonable calculation of air volume requirements, and selection of appropriate fan and pipeline layout. By designing a scientific oxygenation plan and regular maintenance, the dissolved oxygen level in fish ponds can be effectively increased, promoting the healthy growth of fish.
