The magnetic levitation high-speed centrifugal blower is a new type of high-efficiency, energy-saving and environmentally friendly blower formed by integrating magnetic levitation bearing technology and high-speed motor technology into the traditional fan, with the remarkable advantages of simple structure, high efficiency and intelligence, integration, simple operation and maintenance, and low operating costs. manufacturing, iron and steel metallurgy, flue gas desulphurization and other projects, with remarkable energy-saving effect.
The magnetic levitation high-speed centrifugal blower adopts the direct-drive structure of high-speed permanent magnet synchronous motor, integrating the centrifugal impeller and motor drive into an integrated design, which detects the vibration and space clearance of the rotor shaft in real time through the built-in displacement sensor, and sends the obtained signal to The signal is fed into the magnetic bearing controller for conditioning, analysis and calculation to produce a control current. This current is then fed into the magnetic bearing winding coil to generate electromagnetic force, thus achieving the levitation of the rotor shaft. This current is then fed into the magnetic bearing winding coil to generate the electromagnetic force that levitates the shaft.
The main function of the permanent magnet synchronous motor is to drive the rotation of the rotor shaft. The main function of the permanent magnet synchronous motor is to drive the rotation of the rotor shaft. This current is fed into the rotating magnetic field generated by the motor stator and drives the rotor shaft to rotate at high speed.
The main function of the fan is to achieve air blowing, along with the rotor shaft to do high-speed rotation of the impeller to drive the air, to do work on the air. The impeller rotating at high speed with the rotor shaft drives the air and does work on the air, which enters through the air inlet collector of the worm housing. The air is guided and pressurised by the worm gear into a gas with a certain flow rate and pressure. The air is guided and pressurised by the worm and becomes a gas with a certain flow rate and pressure, which is finally blown out through the outlet of the worm. The air is guided and pressurised into a gas with a certain flow rate and pressure.

Kunming Fan Branch was established in 1994, which has been serving all walks of life in Yunnan Province for many years and has gained a good reputation in the market. Due to the restructuring of the factory and other reasons, the name was changed to Kunming Chuangu Machinery Equipment Co. We will continue to provide high-quality, honest pre-sales, in-sales and after-sales services to Yunnan and surrounding areas, and your satisfaction is our greatest wish. 
The company has implemented the reform of the property rights system and established a corporate governance structure and an efficient and lean decision-making management structure according to the requirements of the reform, and has initially established a modern enterprise system. The various management systems are standardised and complete, and a number of work has been commended by the province and city. 
Ltd. has developed high-speed magnetic levitation blowers through external cooperation and production, i.e., as an agent for imported Korean brand high-speed air levitation blowers in the southwest region (Yunnan, Guizhou, Sichuan and Chongqing areas).
After three phases of technical transformation, the company has now formed an annual production capacity of 2,000 units of various types of fans, a variety of processing means and supporting facilities, built a microcomputer automatic detection device, CAD-aided design and microcomputer information management system. The main products include 35 types of Roots blowers in 7 series from L4LD(WD) to L10WDA, more than 860 different types of centrifugal ventilation (induced) fans and centrifugal blowers, and 9 types of automatic stone cutting machines in 3 series. The newly developed 3R low-noise Roots blower products are unique for their energy saving and environmental protection and are at the leading level in China. The products developed and produced by the company have been awarded the "Second Prize of Roots Blower Renewal Research" by the Ministry of Machinery Industry, "Provincial Excellent New Product", "Second Prize of Provincial Scientific and Technological Progress" and "Ministry Excellent Product Award". "Our products are mainly sold in domestic market and exported to Vietnam, Laos, Myanmar, Russia, etc. We have set up 18 offices in China and established a perfect marketing network. Our products are widely used in environmental protection, building materials, chemical industry, metallurgy and other fields.
