Although the second-generation resident ID card has entered the normal issuance stage, but do not forget that China has a large population, many people each year want to receive the first ID card of life, plus the factors such as re-submission, the annual second-generation card is also maintained The number of 50-60 million pieces is over 300 million over five years, which is not a small number.
Hu Xiaoyi, deputy director of the Ministry of Human Resources and Social Security, recently revealed that in the next five years, social security cards will be popularized throughout the country and the number of cards issued will reach 800 million. This will be another industry card that will be developed vigorously by the country following the second generation of certificates.
The popularity of bank IC cards has risen. 2010 is the first year of IC card startup. From this year, the development speed of IC cards will be further accelerated. In the past, more than 200 million magnetic cards were added each year, although magnetic cards will not Immediately out of the market, but the trend of shrinking will be gradually carried out, and conservatively expect that in the next five years, the number of bank IC cards will have more than 300 million.
The field of city card has entered the stage of CPU card development. In the next five years, the issuance of CPU cards will be the mainstream products, and the market capacity will be 200 million.
The rapid development of urban rail transit will usher in a golden period of development during the “Twelfth Five-Year Plan†period. By then, nearly 30 cities will open rail transit lines with a total length of more than 2,700 kilometers and over 100 new lines, one-way ticket cards. The conservative is expected to exceed 150 million.
The construction of high-speed rail will be a major infrastructure project during the “12th Five-Year Plan†period. The total investment will exceed 1.8 trillion yuan, and the construction of new high-speed railways will exceed 16,000 kilometers. The construction of high-speed railways will promote the informationization revolution of train tickets and the traditional magnetic ticket. It will be gradually replaced by non-contact IC cards. Huge passenger flow will greatly promote the application of IC cards in the high-speed rail field. It is conservatively predicted that there will be 500 million high-speed rail tickets in the next five years.
In addition, the campus area will continue to maintain a relatively stable application in the next five years, and it is predicted that there will be 200-300 million pieces; with the full issuance of the two major oil companies, the number of refueling cards will exceed 100 million. And so on, the list goes on.
With the number of applications mentioned above exceeding 6.5 billion, coupled with other foreseeable applications and unforeseen applications and a large number of exports, we can boldly predict that at the end of the "Twelfth Five-Year Plan", China will The IC card industry sector will supply more than 12 billion IC cards to the market in five years. The market is large and cannot be underestimated.
High-Efficiency Centrifugal Blower
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.
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
