How can we select an air suspension blower with an appropriate power according to our own requirements?

Selecting an air suspension blower with the right power requires comprehensive consideration of multiple factors. The following are the specific steps:

Determine the Required Airflow

Calculate the Actual Demand: Based on the application scenarios, such as sewage treatment plants, industrial aeration tanks, etc., calculate the required air flow through relevant formulas or empirical data. For example, in sewage treatment, the required aeration volume can be determined according to parameters such as the amount of sewage, aeration time, and the volume of the aeration tank. Generally, it is calculated based on the amount of air required per cubic meter of sewage per hour.

Consider the Margin: To ensure the stable operation of the system under different working conditions, a certain margin should be considered. It is usually recommended to increase the air flow by 10% - 20%. For instance, if the calculated actual required air flow is 100 cubic meters per hour, then the air flow of the selected blower should be around 110 - 120 cubic meters per hour after considering the margin.

Determine the Required Air Pressure

Analyze the System Resistance: The air pressure of the air suspension blower needs to overcome the resistance generated by the air supply pipeline, aeration device, water head, etc. Conduct a resistance analysis of the entire air supply system, including factors such as the length, diameter of the pipeline, the number of elbows, the type of valves, as well as the resistance characteristics of the aeration device and the water depth. For example, the longer the pipeline and the more elbows there are, the greater the resistance; the smaller the micropores of the aeration device, the greater the resistance as well.

Determine the Safety Margin: Similarly, for the reliability of the system, a certain safety margin should also be reserved for the air pressure, generally 20% - 30%. Suppose the total calculated system resistance is 50 kilopascals, then the air pressure selected after considering the margin should be around 60 - 65 kilopascals.

Refer to the Application Scenarios

Sewage Treatment: Different sewage treatment processes have different requirements for air flow and air pressure. For example, the activated sludge process requires a relatively large air flow to provide sufficient oxygen to maintain the growth and metabolism of microorganisms; while the biofilm process has a relatively lower requirement for air flow, but a higher requirement for the stability of air pressure.

Industrial Aeration: In the aeration processes of industries such as chemical engineering, food, and electronics, determine the required air volume and pressure according to the process characteristics and production scale. For example, in the aeration and stirring in the chemical industry, the appropriate power of the blower needs to be selected according to factors such as the size of the reaction kettle and the properties of the materials.

Consider Efficiency and Energy Consumption

Energy Efficiency Ratio: Select an air suspension blower with a high energy efficiency ratio, which can save a large amount of energy costs during long-term operation. Check the performance curve of the blower to understand its efficiency performance under different working conditions, and choose a model with a higher efficiency near the expected operating point.

Variable Speed Adjustment: If there are significant changes in the requirements for air flow and air pressure under actual working conditions, an air suspension blower with variable speed adjustment function can be selected, such as using variable frequency speed regulation technology. In this way, the speed of the blower can be adjusted in real time according to the actual demand, thus achieving energy-saving operation. For example, in different operation stages of a sewage treatment plant, adjust the power output of the blower through variable frequency speed regulation according to the changes in the amount and quality of sewage, to avoid energy waste caused by fixed-speed operation.

Consult Professionals and Manufacturers

Seek Professional Advice: Consult experienced engineers, designers, or industry experts. They can provide reasonable selection suggestions according to the specific application scenarios and process requirements. For example, in the field of sewage treatment, professional water supply and drainage engineers can accurately recommend an air suspension blower with an appropriate power according to factors such as the design scale and process flow of the sewage treatment plant.

Technical Support from Manufacturers: Contact the manufacturers of air suspension blowers, provide detailed working condition parameters and technical requirements. The technical personnel of the manufacturers will select the appropriate model and power according to the characteristics and performance data of their products, and provide corresponding technical support and solutions. At the same time, the manufacturers can also provide product samples, technical materials, etc., to help you better understand the product performance and characteristics.
