Project introduction

At present, traditional fluid equipment such as blowers and air compressors are widely used in the production process of the cement industry. Such traditional equipment has problems such as high energy consumption, low efficiency, oil leakage, frequent maintenance, short service life, vibration and wear. At the same time, the noise generated during operation is 110-130db, which has exceeded the requirement of not higher than 85dB specified in the national standard and seriously damaged the physical and mental health of the operators.

Taking the traditional roots blower as an example, its roles are the coal feeding fan at the kiln head and kiln tail, the primary air fan at the kiln head, the fan at the homogenization silo, etc. during operation, the roots blower is driven by the asynchronous motor, and the vibration is large. The gears and bearings need regular lubrication and maintenance, and the mechanical friction causes great energy consumption, noise, wear and other problems.

Aiming at the defects of traditional fluid equipment such as roots blower, Shandong Tianrui Heavy Industry Co., Ltd. has successfully combined magnetic levitation technology with rotary fluid machinery, and developed a new type of industrial fluid equipment - magnetic levitation blower, which is energy-saving, efficient and environmentally friendly.

The maglev blower developed by Tianrui heavy industry has been widely used in the cement industry. After many years of practical tests, it has been proved that it can completely replace the traditional roots blower in performance, and at the same time, it has solved the defects of the traditional blower such as high energy consumption, high wear, high maintenance cost, and large vibration and noise.

The maglev blower developed by Tianrui heavy industry is a high-tech green energy-saving and environmental protection product. Advanced magnetic bearing, three-dimensional flow turbine, high-speed permanent magnet synchronous motor, high-speed variable frequency speed regulation, intelligent monitoring and control and other core technologies are adopted. When it is started, it is suspended first and then rotated, without friction and lubrication. The turbine and rotor are directly connected, and the transmission is zero loss. Compared with roots blower, it can save 30% - 40% energy and reduce the noise from 128 DB to below 80 dB. It is intelligent remote control and has a service life of up to 20 years. The scientific and technological achievements evaluation meeting of Maglev blower composed of experts from China Construction Machinery Industry Association, Tsinghua University and China Institute of standardization concluded that the overall performance and energy-saving and noise reduction technology of the maglev blower developed by Tianrui heavy industry have reached the world advanced level.

Weifang Municipal government vigorously supports the development of magnetic levitation industry and invests in the construction of magnetic levitation production base. The total investment in phase I is 300 million, covering an area of 67.8 mu, forming an annual capacity of 1500 magnetic levitation blowers. In phase II, a production capacity of 10000 sets of Maglev series products will be formed. At the same time, a Chinese maglev town integrating industry and city will be built.

Tianrui maglev blower has opened a new era of energy saving, safety, low noise and low maintenance cost. From site selection, installation to commissioning, professional and technical personnel conduct zero distance field operation and guidance, from early technical guidance to later technical support, and one-to-one tracking service. It is widely used in municipal and industrial sewage treatment, cement, thermal power, papermaking, chemical industry, food, pharmaceutical, brewing and many other industries with leading technology, excellent quality and considerate service. It has set up more than 10 provincial agents and more than 100 regional agents in China and gradually expanded the overseas market.

Tianrui heavy industry's magnetic levitation technology has reached the international advanced level and is the first to implement the ISO international standard in China. Strict quality control, the quality spirit of excellence and the craftsman spirit of excellence have become the eternal pursuit of Tianrui people, and improve the manufacturing level of China's high-end equipment.

Tianrui heavy industry will integrate industrial resources, expand industrial scale, focus on research and development and exploration of China's magnetic levitation technology, create world-class Z high-quality products and services, build Tianrui heavy industry Magnetic Levitation Technology Industrial Park, and build China's magnetic levitation 10 billion level industrial demonstration base.
