Greenhouse gas emissions and the accumulation of persistent organic pollutants have caused more and more damage to the Arctic environment. Polar bears are gradually losing their habitats. Recently, this newspaper has continuously reported on China’s first college student Arctic expedition. The news has caused people to pay attention to the Arctic environment. The expedition team members launched an initiative in New Orleans, Norway: caring for the earth, caring for our homeland, and stopping the damage to the environment caused by bad lifestyles.
The delegates attending the 11th National People's Congress in Beijing also paid close attention to environmental protection and ecological civilization, and sought a way to save energy and reduce emissions and transform economic development.
Promote sustainable development
After coal gasification, the coke produced by the coke oven is used as steelmaking, and the coke oven gas produced can be used as gas in the city. The carbon dioxide produced in the production process is used to produce food grade carbon dioxide (dry ice), sulfur dioxide can produce sulfuric acid and fertilizer ammonium sulfate, and slag is used as municipal building materials... This is the whole process of coal processing by Shanghai Coking Co., Ltd. After such refining, black coal has become a treasure, and even waste gas and slag have become waste, reducing pollutant emissions and becoming an example of circular economy. Wang Xia, a representative from Shanghai Coking Co., Ltd., deeply understands that the comprehensive utilization of resources and the promotion of circular economy are the sustainable development of Shanghai's chemical industry.
A fuel cell sedan that "drinks" hydrogen energy and discharges clean water to achieve "zero emissions" will be unveiled at the 2010 Shanghai World Expo; another hybrid electric vehicle, which was officially launched by Shanghai GM in February this year, The model will be available during the year. Chen Hong, a representative from SAIC, said that the development of new energy vehicles is an important measure for SAIC to respond to the national energy strategy, fulfill its corporate social responsibility and practice the scientific development concept. SAIC is currently steadily advancing the work of new energy vehicles.
Energy saving and emission reduction fund
Premier Wen Jiabao stated in the government work report that this year is a crucial year for completing the "Eleventh Five-Year Plan" energy conservation and emission reduction targets. It is imperative to strengthen the sense of urgency and intensify the efforts to achieve greater results.
Many representatives pointed out that to achieve the "Eleventh Five-Year Plan" to complete the 20% energy-saving emission reduction task, we need to go beyond the conventional thinking and seek an operational incentive mechanism to accomplish this arduous task with innovative ideas.
Energy-saving lamps are more energy-efficient than incandescent lamps, but energy-saving lamps are much more expensive than incandescent lamps, and the market sales are not going up; old houses are wearing "energy-saving clothes" and replaced with double-layer insulating glass, and the heat preservation property is increased by 20% at once, but one building The renovation cost of the building is as high as five or six hundred thousand, which is difficult to promote...
At the two national conferences, Ye Qian, who has been engaged in building energy-saving technology research for a long time, put forward a special proposal: setting up an energy-saving and emission-reducing fund.
Ye Qian said that the energy-saving and emission-reducing products usually have higher technical content, and the low output is just introduced, so the products are usually more expensive. It is recommended that Shanghai set up energy conservation and emission reduction funds to promote a virtuous circle of energy conservation industries. The source of funding is based on the dependence of the production of various types of enterprises on energy, setting different payment standards, paying the energy conservation and emission reduction fund, and the government finance should also invest in the fund.
Developing solar potential
China is facing the dual pressure of sustainable energy supply and environmental protection. The application of solar energy is an effective way to alleviate this “double pressureâ€. Yan Junhao, deputy of the National People's Congress and academician of the Chinese Academy of Sciences, said that at present, the development and application of solar energy at home and abroad is paying more and more attention. The calculations show that in Shanghai, the solar energy received in one year in an area of ​​about 50 square kilometers is equivalent to the power generation of Shanghai Power Grid in one year. It can be seen that solar energy is a clean energy with great development potential.
However, the development and application of solar cells in China have both technical problems and policy problems. China has consumed a large amount of electricity and capital to prepare solar cells (99.9999% of pure polysilicon needs to be imported), but since solar power generation is more expensive than hydropower and thermal power, the prepared batteries are mainly exported abroad. As a result, China’s energy and resources are consumed, but energy is saved for other countries. To solve this problem, we must first tackle the problem from the technical point of view. At the same time, it is recommended to develop support policies to promote solar cells mainly for domestic use.

Dc Gear Motor can be defined as an extension of Dc Motor which already had its Insight details demystified here. A dc gear motor has a gear assembly attached to the motor. The speed of motor is counted in terms of rotations of the shaft per minute and is termed as RPM .The gear assembly helps in increasing the torque and reducing the speed. Using the correct combination of gears in a dc gear motor, its speed can be reduced to any desirable figure. This concept where gears reduce the speed of the vehicle but increase its torque is known as gear reduction.
Application field: usually used Electronic door locks, shutter motor, home audio equipment, sweep the floor machine robot
Features: dc gear motor drive precision, small volume, large torque, low noise, durability, low energy consumption, customized power design,easy installation, easy maintenance;Simplify design and save space.
Method of use: the best stable in horizontal plane, installed on the dc gear motor output shaft parts, cannot use a hammer to knock,knock prone to press into the dc gear motor drive, may cause damage to internal components, and cannot be used in the case of blocked.
Operating temperature range:
Dc geared motors should be used at a temperature of -10~60℃.
The figures stated in the catalog specifications are based on use at ordinary room temperature catalog specifications re based on use at ordinary room temperature (approximately20~25℃.
If a geared motor is used outside the prescribed temperature range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.Depending on the temperature conditions ,it may be possible to deal with them by changing the grease of the motor's parts.Please feel free to consult with us about this.
Storage temperature range:
Dc geared motors should be stored ta a temperature of -15~65℃.
In case of storage outside this range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.
Service life:
The longevity of dc gear motor is greatly affected by the load conditions , the mode of operation,the environment of use ,etc.Therefore,it is necessary to check the conditions under which the product will actually be used .The following conditions will have a negative effect on longevity.Please consult with us should any of them apply.â—Use with a load that exceeds the rated torque
â—Frequent starting
â—Momentary reversals of turning direction
â—Impact loads
â—Long-term continuous operation
â—Forced turning using the output shaft
â—Use in which the permitted overhang load or the permitted thrust load is exceeded
â—A pulse drive ,e.g.,a short break,counter electromotive force,PWM control
â—Use of a voltage that is nonstandard as regards the rated voltage
â—Use outside the prescribed temperature or relative-humidity range,or in a special environment.
â—Please consult with us about these or any other conditions of use that may apply,so that we can be sure that you select the most appropriate model.
