According to news from Beijing on July 31, the Ministry of Industry and Information Technology of China stated that steel, electrolytic aluminum, cement, flat glass and other industries with serious excess production capacity will implement equal or reduced replacement of production capacity and ensure new (reform, expansion) construction. The project will not add capacity.
The press release published on the website of the Ministry of Industry and Information Technology on Thursday stated that it was clear that only those companies included in the announcement of the Ministry of Industry and Information Technology in 2013 and later eliminated outdated and surplus production capacity before they could be used for new (reconstruction, expansion) project capacity replacement, and reuse. The outdated production capacity that has exceeded the time limit for the state's explicit elimination cannot be used for capacity replacement.
"Implementing equal or reduced replacement of production capacity is a policy for 'outside the way'," said the Ministry of Industry and Information Technology.
The Ministry of Industry and Information Technology expressed that it is necessary to take into account the actual needs of local development of the economy, industrial upgrading and adjustment of the layout, and overall arrangements for the relationship between elimination and withdrawal and transformation and upgrading, and to mobilize the enthusiasm and initiative of localities and enterprises. The replacement of production capacity will not only facilitate the elimination of backward and excess production capacity, but also facilitate the adjustment and upgrading of inventory capacity and layout optimization, in particular, control of total production capacity, avoid “overdue and surplusâ€, ease local economic development, eliminate backward production capacity, and eliminate production capacity. Excessive contradictions, promote work as quickly as possible.
The Ministry of Industry and Information Technology requires that all new construction, reconstruction and expansion projects in the steel, electrolytic aluminum, cement, and flat glass industries must formulate capacity replacement programs to meet the requirements for equal or reduced replacement and achieve total capacity control. At the same time, it will guide local governments to speed up the elimination of backward and surplus production capacity, release resources, environmental capacity and market space for the implementation of new projects, and promote the optimization of industrial layout and structural upgrading. Adhere to market regulation and government guidance combined. In accordance with the decisive role of market allocation of resources and better fulfillment of the role of the government, in the replacement of production capacity, all localities are encouraged to explore and implement capacity index trades that are government-led, voluntary, and market-oriented, play a market role, and support cross-regional production capacity. Replacement improves resource allocation efficiency.
Taking into account the differences in resource advantages and environmental capacity in different regions, differentiated treatment of capacity replacement is implemented. For environmental sensitive areas such as the Beijing-Tianjin-Hebei region, the Yangtze River Delta, and the Pearl River Delta, reductions and replacements will be implemented, and other areas will be replaced by equal amounts.
The capacity replacement program for the cement and flat glass industries was confirmed by local governments, while the capacity replacement program for the steel and electrolytic aluminum industries was confirmed by the Ministry of Industry and Information Technology.
“The replacement of production capacity by equal or reduced capacity is a transitional measure that prohibits new production capacity, controls total production capacity, and gradually resolves the problem of overcapacity in the case of severe overcapacity in some industries. It is not a permanent policy. The Ministry of Industry and Information Technology said.
In response to the serious overcapacity problem in China, Huang Qunhui, head of the Institute of Industrial Economics of the Chinese Academy of Social Sciences, previously stated that resolving excess capacity is the focus of current and long-term transformation of economic development methods and the promotion of industrial restructuring; Seventy percent of companies believe that the overcapacity solution needs more than three years.
This is about Centrifugal Fan
Centrifugal fan is to rely on the input of mechanical energy, increase gas pressure and send gas machine, it is a kind of driven fluid machinery. Centrifugal fans are widely used in ventilation, exhaust and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings; ventilation and draft in boilers and industrial furnaces; cooling in air conditioning and domestic appliances and Ventilation; grain drying and selection; wind tunnel source and hovercraft inflatable and propulsion.
Centrifugal fan works with turbine compressor basically the same, are due to the gas flow rate is low, little pressure change, generally do not need to consider the gas volume change, that is, the gas as incompressible fluid treatment.
Centrifugal fan can be made of right-handed and left-handed two types. Faced from the motor side: impeller clockwise rotation, known as the right rotary fan; impeller counterclockwise rotation, known as the left rotary fan.
Centrifugal fan from the chassis, spindle, impeller, bearing and motor drive and other components.
Chassis: made of steel sturdy and reliable, can be sub-integral and semi-open, semi-open for easy maintenance.
Impeller: the blade, curved front plate and plate rear plate composition.
Rotor: Static and dynamic balance should be done to ensure smooth rotation, good performance.
Transmission parts: a spindle, bearing boxes, rolling bearings and pulleys (or coupling) composition
Features
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
