Technical principles
1. Air suspension bearings: using air bearings, no lubricating oil required, belonging to semi maintenance free bearings; Traditional single-stage centrifugal blowers use mechanical bearings and require a special lubrication system for the machine to operate normally. Generally, the oil needs to be changed regularly once or twice a year.
2. Bearing lifespan: The air suspension blower has started and stopped more than 20000 times, with a daily start stop cycle lasting up to 50 years. It is a semi permanent bearing and does not require any maintenance during operation; Traditional single-stage centrifugal blowers only take 5-8 years, and generally require major maintenance every 3 years or so
3. Motor: The air suspension blower adopts a DC permanent magnet motor with a high speed of up to 100000 revolutions per minute; Traditional single-stage centrifugal blowers use AC induction motors, which can only reach high speeds up to 4000rpm.
4. Transmission method: The motor of the air suspension blower is directly connected to the turbine, with an efficiency of over 99.5%. Traditional single-stage centrifugal blowers use gearbox transmission, with a transmission efficiency of only 69-98%.
5. Control technology: The air suspension blower adopts advanced frequency conversion control technology, and the control system is advanced; Traditional single-stage centrifugal blowers do not have frequency conversion control (using traditional mechanical guide vane adjustment, which consumes a lot of energy), and the control system is outdated.
6. Operating efficiency: The air suspension blower adjusts the air volume through frequency conversion, which not only ensures high efficiency at the design operating point, but also maintains good efficiency under fluctuating air volume and pressure conditions; The traditional single-stage centrifugal blower adjusts the opening of the inlet and outlet guide vanes through mechanical means, which has a slow reaction speed, small range, and difficult operation. The efficiency is high at operating points, but at non operating points, the efficiency drops sharply, with a decrease of more than 30%.
7. Fan structure: The air suspension blower has no bearings, no gearbox, no couplings, and no lubrication system. It has a simple structure, few components, low failure rate, and low maintenance costs; The traditional single-stage centrifugal blower has a complex structure, including bearings, gearboxes, couplings, lubricating oil systems, etc., numerous components, high failure rates, and high maintenance costs.
8. Installation area: The air suspension blower has a simple structure, small volume, and occupies a small area; The traditional single-stage centrifugal blower has a complex structure, large volume, and occupies a large area.
9. Daily maintenance: The air suspension blower only needs to be cleaned or replaced with filter cotton, and no other maintenance is required; Traditional single-stage centrifugal blowers require maintenance or replacement of filter cotton, lubricating oil, bearings, oil temperature switches, oil level switches, cooling systems, and guide vane systems.
10. Fan noise: The air suspension blower has low noise, basically between 75-80 dB (A); The traditional single-stage centrifugal blower has high noise, generally between 85-95 dB (A).
11. Attachment noise: The air suspension blower has no other noise sources except for normal air flow noise; Traditional single-stage centrifugal blowers have other noise sources besides normal air flow noise, such as bearing noise, coupling transmission noise, gear transmission noise, etc.
12. Maintenance cost: AERZEN air suspension blower requires almost no additional maintenance cost; Traditional single-stage centrifugal blowers require normal maintenance at a cost of 5000-20000 yuan per unit, which is expensive and increases over time.
13. Technological maturity: Air suspension has a longer application time and more mature technology than traditional single-stage centrifugation.
14. Application scale: Traditional single-stage centrifugation requires high machining accuracy, and the impeller diameter cannot be made too large. Currently, it can only achieve 250kw; The diameter of the impeller of the air suspension blower can be made very large, currently up to 1000kw. So in large-scale projects, traditional single-stage centrifugation is more suitable.

Product characteristics

1. Energy saving and efficient
The air suspension centrifugal blower uses air bearings, direct connection technology, high-efficiency impellers, permanent magnet brushless DC motors, and no additional friction. The fan automatically adjusts the power consumption of the motor based on the output (adjustable air volume range of 40-) to maintain high efficiency in equipment operation. Generally speaking, after technological transformation, it can save 30% -50% energy compared to the original equipment and increase the surplus by 15% -20%.

2. No vibration, low noise
Using air bearings and direct connection technology, there is no vibration generated, and the fan does not need to be equipped with sound insulation devices; The equipment is lightweight, does not require special foundations, and has simple and flexible installation and layout.

3. No lubricating oil
The fan adopts air bearing technology, and the system does not require a lubricating oil system, providing clean air to special industries such as electronics, medicine, and food. The operating temperature of the air bearing reaches 600 degrees, and all the drawbacks of the oil bearing system have been successfully resolved.

4. No maintenance
Without the necessary gearboxes and oil bearings for traditional fans, we use a series of high-tech impellers and motors that do not use couplings, are directly connected, and have an intelligent control system. The key components are made of AL7075 (aviation aluminum), which ensures that the equipment is maintenance free, reduces maintenance costs for users, and improves the stability of the gas supply system operation.

5. Convenient operation control
The fan speed, pressure, temperature, flow rate, etc. can be self checked and operated at constant pressure on a personal computer, with load/no-load operation, overload control, and unmanned operation through anti surge control. The fan adjusts the flow rate by adjusting the speed of the impeller. Adjusting the speed can easily regulate the flow rate based on the temperature and pressure changes of the inhaled air. It can automatically and manually adjust the flow rate.

6. Small installation space for equipment
The air suspension centrifugal blower equipment is lightweight, small in size, easy to install, and can greatly save users' investment in building and auxiliary electrical control systems.

Safe operation and maintenance

When installing an air suspension fan, in order to better ensure the installation quality of the fan equipment, it is not only necessary to strictly follow the correct installation method, but also to pay more attention to some operational details that are easy to overlook and make mistakes, so as to better ensure the installation quality of the fan equipment. So now the editor will talk about the four major precautions when installing this fan equipment.

1. When installing the air suspension fan, the adjustment bolts of the motor should be in a convenient position for operation. To facilitate the adjustment of belt tension during use.

2. After the installation of the air suspension fan, the sealing around it should be checked. If there is an open space, it can be sealed with a sun panel or glass glue.

3. When installing the bracket, it is necessary to ensure that the bracket is level and stable with the foundation plane. If necessary, install angle iron next to the air suspension fan for further reinforcement.

4. Stable installation: When installing, pay attention to the horizontal orientation and adjust it to be level and stable with the foundation plane. The motor behind the device should not have any skewed appearance.

Therefore, when installing air suspension fans, everyone must pay more attention to the points mentioned by the editor above, so as to better avoid installation errors and other phenomena. At the same time, after installing the fan equipment, it is necessary to conduct a trial operation test to ensure that the fan equipment can operate normally before it can be put into use. This not only improves the safety of use, but also avoids the occurrence of abnormal faults in the fan equipment.
