Key points of two-stage screw air compressor exceeding the first level of energy efficiency:
Compared with single-stage compression, two-stage compression tends to be the most energy-efficient isothermal compression. In principle, two-stage compression is more energy-saving and power saving than single-stage compression.
The use of two-stage compression host means that two groups of screw rotors with different sizes are used to achieve reasonable pressure distribution and reduce the compression ratio of each compression. The low compression ratio has two special advantages. One is to reduce internal leakage and improve volumetric efficiency. The other is to greatly reduce the bearing load, improve the bearing life and extend the service life of the main engine.
Leading rotor profile efficiency in the world
Professional development of "T" type lines, leading the world in efficiency and higher than other types of lines.
High end configuration and system optimization
The key points are also reflected in the local design and details of the product, as well as the high-end configuration and optimization of the system, which is more efficient than other brand products. The highly efficient imported main engine and the innovative technologies of Qimai series, such as the inherent intake air regulation design, the smooth cooling design, the oil gas separation technology, the highly efficient motor, the intelligent control, will bring real energy and power saving benefits to customers at home and abroad
Market application
1 ＞ As a universal machine, air compressors are widely used in various fields of national production, such as metallurgy, forging, mining, automobile, industrial automation, textile, food, etc. They are energy consuming products with large quantities and wide range, and their annual power consumption accounts for about 9% of the total power generation in the country.
2 ＞ However, in the industrial use of compressed air, only 60% of the energy consumption is used for production, and the remaining 40% of the energy is wasted on the unmatched load of power equipment, unreasonable gas consumption of terminal equipment, and unscientific configuration of gas supply pipe network.
3 ＞ During the customer's on-site inspection, many normal pressure air compressors operate under the pressure of 0.3~0.5MPa, resulting in huge energy waste.
4 ＞ Our low pressure compressor, magnetic suspension, air suspension, etc. came into being under this industrial application background. Their pressure range is 0.2~0.5MPa, allowing customers to choose air compressors with corresponding pressure for different use environments, so as to achieve the purpose of energy conservation.
5 ＞ Our low press is especially suitable for textile, chemical fiber, fermentation, glass, cement, ceramics, printing and dyeing, chemical powder conveying and other industries at home and abroad.
