Suspended centrifugal fan

Features of the air suspension centrifugal fan: 1. Low energy consumption: The permanent magnet high-speed motor is directly connected to the drive design and operates using frequency conversion technology, which is efficient and energy-saving, saving more than 30% energy compared to traditional blowers. N2. High efficiency: Air suspension bearings operate frictionless with the shaft, achieving an operating efficiency of over 80% $n3. Clean air: The entire system uses air lubrication and a simple and effective cooling system, with 100% no need for lubricating oil. 4. Less maintenance: The integrated device has a simple structure and easy replacement of parts, making it convenient for customers to perform maintenance and upkeep. $n5. The device occupies a small area and does not require additional infrastructure, saving customers

Application scenarios of air suspension centrifugal fan:

1. Sewage treatment aeration system

2. Power plant desulfurization and oxidation air system

3. Various powder conveying fields

4. Drying (dehydration) and food, pharmaceutical and other industries

　　1. Efficient and energy-saving, with an energy-saving rate of 20-50%

The air suspension centrifugal fan uses a high-speed permanent magnet synchronous motor (PMSM), air bearings, high-efficiency impellers, and direct connection technology. The motor system has a conversion efficiency of over 97% at full load and no power transmission energy loss. The high-speed variable frequency speed control system of the fan configuration achieves low current soft start of the permanent magnet motor (PMSM), and automatically adjusts the power consumption of the motor according to the output air volume (range 40-100%) to maintain high efficiency of equipment operation.

　　Green and environmentally friendly, low noise/100% oil-free

By using air bearings and direct connection technology, the system's dynamic and static components have no physical contact and do not require a lubricating oil system. There is no near zero vibration during operation, and the noise is reduced by 20-30 dB compared to traditional fan devices. There is no noise pollution, and the fan does not need to be equipped with auxiliary sound insulation devices; The system provides green, 100% oil-free clean air to the outside.

　　Intelligent control, unmanned/remote management

The air suspension centrifugal blower is integrated with an intelligent local PLC control system, which does not require a local control cabinet or soft start cabinet. During operation, it self checks the operating parameters, freely adjusts the air volume and pressure according to external control signals, and has anti surge function; After simple training, the relevant technical personnel can automatically put the fan into operation and achieve unmanned operation according to the program settings in the operation manual. At the same time, we can configure an IoT remote management system to achieve 24-hour management of wind turbines through PAD or shouji.

　　Easy operation and maintenance, maintenance free and low maintenance

The air suspension centrifugal blower adopts air cooling design technology and does not have the necessary gearbox, coupling, and oil bearings for traditional fans, so there is no need for maintenance of the oil circuit and water cooling system. Usually, only the air filter element needs to be replaced regularly, making operation and maintenance very convenient and fast, reducing maintenance costs for users and improving the stability of the air supply system operation.

　　High cost-effectiveness and low lifecycle cost

Firstly, the air suspension centrifugal blower equipment is lightweight, small in size, low in vibration, requires a small machine room area, is easy to construct, does not require lifting devices, and can save users a lot of investment in building, auxiliary control systems, and installation. Secondly, the maintenance free and low maintenance feature of the equipment can save users a lot of daily maintenance expenses. More importantly, in the full life cycle cost of the fan, the high ZUI is not the purchase cost, installation cost, or maintenance cost, but the energy consumption cost. Compared with traditional forms of fans, air suspension centrifugal blowers have energy-saving advantages and low ZUI in the full life cycle cost,.

　　Suspended centrifugal fantechnical performance

The technology and performance of air suspension centrifugal fans are based on the principle that a high-speed permanent magnet synchronous motor supported by air bearings and controlled by a frequency converter directly drives the coaxial centrifugal impeller to do work; It is composed of core components such as air suspension bearings, PMSM ultra high speed permanent magnet synchronous motor, high-efficiency and high-precision centrifugal impeller, high-efficiency frequency converter, local PLC control management system, and other accessories.
