Magnetic Suspension Bearing Technology
- Shuoyuan's Magnetic Suspension Centrifugal Blowers employ the in - house five - degree - of - freedom active magnetic suspension bearing technology. Without the need for a lubricating oil circulation system, it can intelligently control the position of the rotor axis, enabling zero - friction rotation of the components. This makes it a genuine semi - permanent bearing. The magnetic suspension bearing is composed of radial magnetic suspension bearings, axial magnetic suspension bearings, and position sensors. The active magnetic suspension bearing uses the magnetic principle to levitate and rotate the blower impeller and the central shaft of the variable - frequency motor. During operation, there is no vibration, friction, or wear, and it is lubrication - free and maintenance - free. Shuoyuan's magnetic suspension bearing features an automatic balance technology algorithm, with over 10,000 signal collections and real - time corrections per second, ensuring stable rotor levitation and smooth power output. The magnetic suspension bearing eliminates the traditional lubrication system, is maintenance - free, and operates 100% oil - free. It is equipped with a power - off protection system, including auxiliary bearings, a UPS power supply, and a bearing controller, providing multiple safety safeguards to avoid bearing damage caused by unexpected power outages and ensuring no damage in case of sudden power outages or malfunctions.

Shuoyuan's Self - developed Anti - interference High - performance Sensor Technology
- The sensor has a collection accuracy of 1um and a collection frequency of 10K, which fully meets the requirements for operations below 80,000rpm. The fully potted one - piece sensor is highly sensitive, has low temperature drift, and excellent anti - interference capabilities. It has strong environmental adaptability and good temperature resistance, reaching the same temperature - resistance level as other parts of the motor. The magnetic pole winding of the magnetic suspension bearing adopts H - class (180℃) insulation. After continuous and stable operation for 1h, the temperature rise does not exceed 60℃, and the working temperature does not exceed 110℃.

High - speed Permanent Magnet Synchronous Motor
- The high - speed permanent magnet synchronous motor independently developed by Shuoyuan Power meets the requirements of low current loss and continuous high - speed operation with its optimized high - speed rotation design. It minimizes high - frequency losses, is highly energy - efficient with an efficiency of up to 98%. With a streamlined motor structure, it has a smaller size, lighter weight, and higher power density, making it suitable for long - term and stable operation under multiple working conditions. The starting current is only 4.5% of the rated current, eliminating the need for an additional starting disk. The impeller is directly connected to the rotor shaft for direct drive, completely eliminating mechanical transmission losses.

Three - Dimensional Flow Impeller
- The impeller of the magnetic suspension centrifugal blower is a three - dimensional flow impeller made of AL7075 aviation forged aluminum with a backward - curved integral design. It is a semi - open impeller directly connected to the motor shaft. Manufactured as a whole from high - strength aluminum alloy, it undergoes static and dynamic balance tests according to ISO1940 standards. Milled by a five - axis machining center and surface - treated with chromic acid anodization for corrosion protection, it is directly fixed on the output shaft of the magnetic suspension high - speed permanent magnet motor and is easy to disassemble and assemble. The design ensures sufficient strength and stiffness, with a safety margin of more than 1.2 times under the maximum speed operating conditions. The efficiency of the centrifugal impeller within the range of ±20% of the rated volume flow is not less than 80%. The precision - cast aluminum volute has a horizontal or vertical suction side and a vertical or horizontal discharge side, depending on the model.

Product Performance Advantages
- High - efficiency: The permanent magnet synchronous motor is the most efficient type in the current motor field. The direct - drive structure of the motor and the impeller directly delivers high efficiency.
- Energy - saving: Compared with Roots blowers and ordinary centrifugal blowers, our magnetic suspension blowers can achieve energy savings of 25 - 40%, making them a new - generation energy - efficient choice.
- Low - noise: Compared with traditional blowers, the operating noise of our blowers does not exceed 80db, reducing noise pollution.
- Maintenance - free: Under the condition of ensuring air quality, the blowers do not require refueling or maintenance during operation.
- Intelligent: Based on PLC - integrated Internet of Things control, it can be intuitively operated through on - site touch screens and remote mobile APP clients, displaying, setting, or communicating real - time operation parameters, status, alarms, and historical records, etc. It has a user - friendly and comprehensive control interface.
- Strong Adaptability: By adjusting the frequency of the frequency converter, the blowers can adjust the air volume and air pressure with a wide adjustment range.
- Long Service Life: The designed service life of each component is more than 3 times that of ordinary blowers.

Application in High - pressure Scenarios
- The core of Shuoyuan's high - pressure magnetic suspension centrifugal blower (integrated unit) is the high - speed three - dimensional flow pneumatic structure, with high - speed motors, high - frequency control, and magnetic suspension bearings all supporting the high - speed rotation of the pneumatic structure. Currently, high - voltage motors rotate relatively stably at low speeds within 100HZ and have been widely used. Due to factors such as insulation materials, rotor materials, and volume limitations, high - voltage motor bodies have not been widely used in high - frequency and high - speed scenarios. Shuoyuan's high - pressure magnetic suspension centrifugal blower (integrated unit) integrates the frequency converter, transformer, permanent magnet motor, fluid working part, and main control system into the same base. It appears as an integrated skid - mounted electrical equipment without other auxiliary equipment and intermediate electrical cable connections. It is suitable for voltage levels such as 1140V, 3300V, 6000V, and 10KV, and can be customized according to user requirements.
