Magnetic levitation vacuum pump

Product Introduction

The magnetic levitation vacuum pump is a new type of turbo vacuum pump developed by Nanjing Magnetic Valley Technology, utilizing core technologies such as magnetic levitation bearings, high-speed high-power permanent magnet synchronous motors, high-frequency output frequency converters, and high-strength ternary flow titanium alloy impellers. Compared to traditional water ring vacuum pumps, this product significantly improves operational efficiency with energy savings of up to 40%.

The core technology of this product lies in the application of the magnetic levitation bearing system. The motor rotor and impeller are directly coupled without the need for a coupling. The rotor is driven by a high-speed permanent magnet synchronous motor and magnetic bearings, completely eliminating mechanical friction. The magnetic bearing power consumption is only about 0.5kW, with transmission efficiency close to 100%, greatly improving overall machine efficiency.

The impeller design adopts ternary flow theory with full three-dimensional flow field analysis, achieving extremely high variable efficiency and covering a suction flow range of 50% to 110% of the working range. The machine employs a combined “external circulation + internal circulation” cooling system, with water cooling for both motor and frequency converter, ensuring high cooling efficiency and long-term stable system operation.

The product features 100% oil-free and water-free characteristics, completely avoiding potential oil contamination issues found in traditional vacuum pumps. System-level noise reduction design keeps operating noise below 80 decibels, providing comfortable working conditions. Operation is achieved through one-button start/stop and visualization, with a four-level power-off protection system ensuring safe and reliable equipment operation.

Industry Applications

The magnetic levitation vacuum pump is mainly applied in production processes for paper manufacturing, VPSA oxygen generation, and alumina industries. Based on its oil-free characteristics, this product is particularly suitable for high-cleanliness vacuum industrial applications, such as semiconductor manufacturing and scientific research laboratories where extremely high environmental cleanliness is required.
