Product Details

Why centrifugal air suspension blower is suitable for stable and constantly running working conditions?
If we want to know the answer of this question,we need to know about the working principle of the air bearing blower:
1.the main parts of the air foil bearing blower is including:high speed permanent magnet synchronous motor,rotating shaft,air foil bearing,thrust bearing,ternary flow impeller,cooling impeller,VFD,PLC control system and other component.cold air blower

2.When the centrifugal air bearing blower connects with the power,the motor will run from low speed to high speed.Since the motor is connecting with the rotating shaft,and shafting connects with the air foil bearing, air foil bearing connects with the ternary flow impeller.The VFD is used for controling the motor running speed.When the motor is running is the speed lower than 8000rpm,the shaft and air foil bearing is touching with each other(If there is connection, there will be friction).The design of the bearing life is start-stop 20,000-100,000times.After the motor running speed is more than 8000rpm,the air force surrounding the air foil bearing will counteract the bearing gravity,then the bearing will float and running surrounding the shaft.mini air blower

3.When the bearing of the air blower is running,it will bring the ternary flow impeller to run(since bearing is connecting with the impeller).After the ternary flow impeller runs,it will generate a vacuum area and suck the surrounding air into the ternary flow impeller,then the air will generate the dynamic pressure under the impeller compression,then the compressed air will be dischaged into the user pipeline.

4.When the shaft is rotating,it will bring the motor cooling impeller to run,the running impeller will form an vacuum area and suck the motor surrounding air inside.The air will go through the motor,bring the hot motor air to the vacuum area,then the hot air will be discharged outside the enclosure of the air blowers.
From the above working principle of air bearing blower,we can know that when we start-stop the blower,the air foil bearing has friction with the rotating shaft,when there is friction,there will be abrasion.Therefore,the air suspension blowers is not suitable for frequently start-stop working conditions.

Air blower technology has evolved over time in many ways to make it more efficient, reliable, and cost-effective. Since the beginnings of air blower technology, blowers have become more tenacious and lighter due to the advent of composite materials and improved engineering techniques.

Initially, most air blowers were powered by combustion engines, typically gasoline or diesel. Despite their efficiency, combustion engines pose a number of potential safety hazards and may be expensive to run. Today, the majority of air blowers are powered by electric motors, sometimes referred to as “turbo” motors, which provide more power with greater energy efficiency.

As far as performance is concerned, most air blowers now feature variable-speed control, which allows users to adjust the airflow output to fit the requirements of the job. Variable-speed control not only makes air blowers more efficient but also reduces the amount of time needed for repairs and maintenance. Additionally, many air blowers today are manufactured with eco-friendly designs that help to reduce energy consumption.

To meet the needs of the commercial market, air blowers are now built with advanced features such as digital temperature control and pressure gauges. This allows users to precisely set the desired temperature and pressure for their applications, while other features like low-noise motors make them easier to operate in quiet environments.

Air blower technology continues to improve, and manufacturers are now putting out models capable of speeds up to 15,000 RPM. This high level of performance helps to increase the efficiency of an air blower’s airflow, resulting in a faster work rate and even greater energy savings.

Overall, air blower technology has seen tremendous improvement over the years, from combustion engines to digital temperature control and high-speed motors. These advancements have helped to bring air blowers into the modern age, offering users greater ease of use and energy efficiency.

4.How long is the service life of an cold air blower?

The service life of an air blower can vary greatly depending on how it is used and maintained. Generally speaking, the life expectancy of an air blower can range from 10 to 20 years, but it can be extended significantly with proper maintenance.

One of the most important elements to ensuring the life of an air blower is proper installation. Before installation, it is important to consult with the manufacturer and ensure that the installation environment is adequate and not overly humid or dry. If the air blower is going to be exposed to any sort of corrosive or caustic atmosphere, additional measures such as protective coatings should be taken to reduce the potential for damage.

Regular maintenance is essential when it comes to air blowers. It is recommended that all filters be checked and changed every 6 months, and that any loosened mounting hardware should be re-torqued. Additionally, oil and grease should be applied to any moving parts to help reduce friction and extend its life.

The air blower should also be regularly inspected to ensure that the blades, bearings, and motors are undamaged and working properly. If any part of the air blower is not functioning correctly, it should be serviced immediately to ensure that it continues to operate efficiently and not risk any further damage to the machine.

Finally, it is important to note that the life of an air blower can be drastically reduced if it is misused or overworked. It is important to always use the blower within the limits recommended by the manufacturer to ensure that it has the proper service life. By following these recommendations, an air blower should last for at least 10 to 20 years, depending on the environment and how well it is maintained over time.

5.What is the operating temperature range of the air blower?

The operating temperature range of an air blower varies depending on the type and size of the blower. Generally, air blowers can operate at temperatures ranging from 40°F (4.4°C) to 250°F (121°C).

Smaller air blowers, such as those found in computers and electronic systems, operate within a much smaller temperature range. These systems typically run between 0°F and 140°F (-17.7°C and 60°C).

Large air blowers, such as those used in industrial or commercial settings, have a much wider operating temperature range. These systems can handle temperatures up to 500°F (260°C). At these temperatures, it is critical to monitor both the air blower and the actual output to ensure the system is not overworking or underperforming.

When designing an air blower system, it is important to select components that are rated for the particular operating temperature ranges. Components made out of materials that can withstand high temperatures, such as nickel-plated brass or stainless steel, are typically best suited for long-term use.

Since air blowers are intended for use in various temperature extremes, it is important to account for any potential changes during operation. Increases in air temperature can lead to decreased performance, while decreases in air temperature can result in decreased output.

Furthermore, all air blowers should be operated within a safe range of temperature to avoid any potential damage to the blower or the surrounding environment. For this reason, regular monitoring of the system should always be conducted to ensure the health and safety of everyone involved.

The air blower size and power depend on the application for which it is used for. Generally, midsize air blowers range from 3-4 to 7-8 horsepower (hp) for small workshops. For large workshops and industrial applications, air blowers with a power of 10 to 20 hp are used. The size of the air blower also depends upon the amount of air flow it needs to generate. Low-power air blowers have a capacity of 100 CFM (cubic feet per minute) and high-power air blowers can range from 600 to over 5,000 CFM.

In addition to the horsepower and air flow measurements, the size of the air blower is determined by its structural dimensions. It includes the width, length, depth and height. Though, small and large air blowers have the same horsepower and air flow, the frame sizes vary. Smaller, more compact blowers are typically more maneuverable and are ideal for operations where space is limited. This makes them more desirable for professional mechanics, hobbyists, and woodworkers. Medium-size air blowers have larger frames, providing higher airflow but have limited maneuverability. This makes these blowers more suitable for large workshops and industrial applications.

The size of the air blower also depends upon its efficiency and portability. Smaller air blowers are lightweight and more efficient in terms of energy consumption compared to larger models. This is the reason why mechanical workshops prefer smaller air blowers as they can be easily placed and adjusted in tight spaces. On the other hand, large blowers require large wall outlets and a large area of operation. Their motors also require more power, which is reflected in their greater energy consumption.
