Using the latest design, in line with the "three of" standard two rows of large spacing cupola, for the current casting industry commonly used in a cupola, the main structural features for the two rows of vents, row spacing larger, bottom coke burning The formation of two independent combustion zone, by stretching the overheating zone, an increase of hot metal overheating and end coke intense combustion, stable furnace conditions, hot metal temperature, hot metal quality. In accordance with the supply air temperature is divided into cold air, furnace hot air two structures, by mining different temperature air supply to achieve different melting requirements.
Centrifugal blowers are widely used in sewage treatment, smelting blast furnace, coal preparation plant, mine flotation, chemical gas, vacuum and other fields, can also be used to transport other special gases.
1. Compact structure: beautiful appearance, good stability, easy installation and maintenance.
2. Smooth operation: Optimized design of the impeller to reduce the axial force to a minimum, and efficient impeller, and static and dynamic balance correction, the machine running smoothly, without any damping device in the case of bearings Amplitude ≤0.04mm.
3. Low noise: blower operation, without any mechanical friction, the use of a reasonable blade-shaped line to the sound to a minimum. Centrifugal blower noise is high-frequency noise, as long as there are obstacles, can be noise, so the fan room almost no noise.
4. Oil-free machinery: Blower bearings with grease lubrication, bearing life of more than three years. Fan does not generate oil and gas during operation. Special requirements fans, with molybdenum disulfide lithium grease lubrication bearings.
5. Impeller: Impeller with a special compound linear, reducing internal leakage and improve the volumetric efficiency.
6 easy to adjust: the inlet valve to regulate flow, the outlet valve to regulate the pressure.
7. Drive: usually using a two-pole asynchronous motor, you can also use four-pole motor drive. Depending on the user grid, different voltage motors can be used.
8. Sealing: In addition to each level of import impeller impeller, the interstage and the housing at both ends with a labyrinth seal to prevent gas leaks.
9. Cooling: exhaust bearing housing has two structures, air-cooled and water-cooled, as the impeller on the level of gas compression, resulting in the exhaust casing temperature is much higher than the intake casing. In the exhaust bearing air-cooled or water-cooled device to extend the bearing life.
10. Bearing temperature control alarm: fan accessories with temperature control box, connected to the bearing through the PT100 resistance, when the bearing temperature exceeds the set temperature, the temperature control box will automatically alarm.
11. Transmission: a coupling drive, belt drive, gearbox drive three. According to different equipment and technology, choose a different transmission

According to the news, the research results of large-scale key forging technology will be widely used in the research and development of large, integral, fine, high-quality, low-cost, long-life die forging products, providing the basis for the manufacture of key components for large aircraft in China. The material smelting and forming control technology of large-scale high-quality castings has been successfully applied in the national major hydropower project “Xiangjiaba 800MW turbine unit†and Sanmen Nuclear Power. It has solved the bottleneck technology related to large castings and forgings that are urgently needed in China's metallurgical and energy industry production equipment.
Relevant industry experts believe that these two key technologies are closely related to high-end CNC machine tools. On this basis, China's overall manufacturing level will reach a new level, and the machine tool industry is expected to gain a share in the high-end market and enhance market influence. In the long run, China's machine tool manufacturing industry will benefit from it. In addition to directly related stocks in China, one heavy and two heavy equipment, Shenyang machine tools, Kunming machine tools and other machine tool manufacturing stocks are expected to be driven.
