100-135 m³/min High-speed Maglev Turbine Blower

Introduction

Due to the working way of magnetic bearing support and high-speed direct drive, the working efficiency of high-speed maglev blower is much higher than traditional blower, furthermore it has advantages of clean, ultra-quite, low maintenance cost and without oil film lubrication.

High speed motor has the advantages of high speed, small volume, high efficiency and high power density. By driving turbine directly with high-speed motor,the speed increasing box and oil supply system of the blower can be omitted, which makes the blower system more compact.

Direct driven high-speed blowers can greatly improve the working efficiency, which has a wide range of applications in sewage treatment, pharmaceutical, chemical and energy fields. Therefore, it is of great significance to improve the performance of high-speed blower for energy conservation and emission reduction.

Composition

The magnetic suspension centrifugal blower is mainly composed of high-speed variable frequency motor, magnetic bearing, impeller, frequency converter.The impeller shaft adopts magnetic bearing, no mechanical friction, and the speed can be as high as 33000rpm.

Magnetic bearings are equipped with backup batteries for power-off protection, monitoring sensor for monitoring the alignment state of bearing in real time, and automatically compensating the alignment and balance of rotor.

Advantages of GoodSeaA Magnetic bearing-levitation centrifugal blower

• High Efficiency: compared with roots blower, the efficiency increases by 30-40%
• Zero pollution: without lubrication, the exhausted air is clean,oil-free and pollution-free
• Low noise: no friction, low operating noise, do not affect the surrounding environment, meet the requirements of environmental protection
• Less emission: taking one set of 100KW equipment as an example, it can reduce carbon dioxide emissions by about 250 tons per year

Technical Principle

The rotor of the magnetic bearing is ferromagnetic, which keeps relative balance and levitation under the action of gravity through the attraction of the upper and lower combined iron batteries; when the external force interferes, the rotor deviates from the original suspension center, and the displacement of the rotor relative to the balance center is detected by the sensor, and the electric state signal which is formed after being sampled by the signal A/ D is transmitted to the controller.

The high-speed computation device in the controller generates real-time control signals after pre-set control logic algorithm calculation, that makes the electromagnetic force on the electromagnet to compete with the external force, and makes the rotor return to the suspension center for continuous and stable operation.

At the same time, the bearing accurately controls the rotor axis position with more than 10000 times signal acquisition per second and real-time correction, and the axis deviation is controlled within 10 μm. With the self balancing technology, the vibration quantity is much less than that of traditional bearing.
