5. The status of wechat is not easy to shake at present. Alipay didn't succeed in shaking WeChat in social interaction, let alone others.
however, in other areas of social networking, wechat has controlled the social networking of acquaintances and offline society, but it still has the potential to develop in stranger social networking and pan social networking
as far as I know, btchat is a social software based on blockchain technology. It focuses on private social networking, as well as payment items related to blockchain. This can be fundamentally separated from wechat, and it can also clearly segment the crowd
just these people, the overall size is relatively small, there are not many people in blockchain circle and coin circle, and there are also very few people who can be attracted
I don't want to sing down all the people who have struggle, but btchat has a long way to go in the social field.

The former is based on the fact that "Jinghua daily" exposes prostitutes and bullies and advocates the establishment of "jiliangsuo", and "plays the role of the wing itself, but also creates the situation by the writer". The latter is based on Huixing, a banner woman in Hangzhou, who advocated women's ecation. Most of the plays are starred by Tian Jiyun, who is praised by the public. He made a lot of speeches in his own newspapers

Sprocket assembly is composed of sprocket and connecting roller. It is an important part of scraper conveyor, and it is also the most torque part of conveyor. Therefore, in the process of purchasing sprocket shaft group, many problems should be considered, and we must be very careful. Only in this way can we choose high-quality sprocket shaft group, prolong the service life of sprocket shaft group, and improve work efficiency, otherwise, In the use of the process is prone to accidents, resulting in labor and money, so what should be paid attention to in the process of purchasing sprocket shaft group? What is the price of sprocket shaft group

what problems should be paid attention to in the process of purchasing sprocket shaft group:

with the development of coal machinery and the national rectification and merger of small and medium-sized coal mines, large-scale fully mechanized mining equipment is more and more widely used in coal mines With the development of heavy-ty scraper conveyor, there are more and more types of scraper conveyor, and the models proced by major coal machine manufacturers are also different. As the main vulnerable parts of scraper conveyor, sprocket shaft group is not universal, which makes it difficult to determine when purchasing. So what problems should be paid attention to when purchasing sprocket shaft group? We summarize the following aspects

First, the main engine manufacturer of sprocket shaft group. As there are many manufacturers of scraper conveyor, the sprocket shaft group of each manufacturer can not be used in general, so when purchasing, we must first determine which manufacturer of scraper conveyor is suitable for sprocket shaft group. At present, the most important domestic scraper conveyor manufacturers are China Coal Zhangjiakou coal machinery plant, Ningxia Tiandi Benniu, Shandong mining machinery, Shanxi coal machinery plant and Zheng coal machinery

Second, the determination of drawing number of sprocket shaft group. Even for the same scraper conveyor manufacturer, the sprocket shaft group applicable to the same scraper conveyor model may not be the same. Therefore, it is necessary to determine the drawing number of the sprocket shaft group. Each sprocket shaft group has only one set of drawings. As long as you find the drawing number of the sprocket shaft group and have the corresponding drawings, you can ensure that the sprocket shaft group proced will not make mistakes

Third, the material selection of sprocket shaft group. Due to the increasing power and transportation volume of scraper conveyor, there are great requirements for the toughness and strength of sprocket shaft group. If the material selection is not appropriate, the sprocket shaft group will be prone to accidents in the use process, affecting the proction progress, and even safety accidents. At present, the commonly used materials are 42CrMo and 45crnimnmu. When selecting, the appropriate materials should be selected according to the transportation volume

Fourthly, the manufacturing process of sprocket shaft group. Due to the high requirements for the toughness and strength of the sprocket shaft group, the manufacturing process can not be careless. At present, the manufacturing process of the sprocket shaft group mainly includes forging, casting and welding. Small ordinary mining scraper conveyor can choose casting and welding sprocket shaft group. For large fully mechanized sprocket shaft group, in order to ensure its performance requirements, only forging sprocket shaft group can be selected, and heat treatment, quenching and tempering and other processes can be carried out

when purchasing the sprocket shaft group, we should pay attention to the above aspects. Basically, the sprocket shaft group can basically meet the performance required by the current scraper conveyor, but there is another point to pay attention to, that is, when the scraper conveyor is running, we must pay attention to the wear of the sprocket shaft group at any time to avoid accidents

the above is about the problems that should be paid attention to in the process of purchasing sprocket shaft group and the price introction of sprocket shaft group manufacturer, In the purchase of sprocket shaft group must be very careful, understand all the situation before making a decision, and in the purchase can not be greedy for small cheap Oh, to buy high-quality procts is the king. At the same time, when using the sprocket shaft group, you should often check the wear of the sprocket shaft group and take preventive measures to avoid accidents. I hope the above contents can help you

10. Research Report on coal machinery instry (China Coal Machinery Instry Association)

I. Introction to the basic situation
since 2000, the rapid growth of coal demand has driven the unprecedented prosperity of coal mining instry, and the coal equipment instry and service instry, which directly provide services for coal mining, processing and utilization, have also entered the fastest development stage in history, because of the scale of coal proction, coal output, coal consumption, and so on The rapid growth of processing quantity, processing depth and mining difficulty has put forward an urgent demand for coal equipment instry and service instry. The significant improvement of financial indicators such as sales revenue and net profit of coal enterprises has greatly enhanced their ability to purchase new equipment. Therefore, the rising demand fundamentally determines that 2006-2010 is the golden period for the development of coal equipment instry<

from the perspective of instrial structure, domestic coal equipment enterprises are generally small in scale and scattered in layout, which means that superior enterprises will have greater comparative advantages in integrating the market, building supporting system, formulating instry standards, etc., and will be easier to stand out, And then grow into a coal equipment giant
from the perspective of equipment level, domestic coal equipment lags behind the international advanced level, and the indicators of equipment reliability, intelligence and informatization are obviously on the low side. However, in the past few years, domestic coal equipment has been continuously improved, and breakthroughs have been made in equipment manufacturing research and development, design and manufacturing
as a big coal country, the gap between domestic high-end coal mining machinery and foreign advanced level is narrowing in recent years, and the market share of domestic procts is also expanding. For example, the domestic hydraulic support market has a total market volume of 2 billion to 3 billion every year, of which the number of imported mechanical equipment is a relatively small part, and the vast majority are domestic equipment
the cost advantage provides domestic coal machinery manufacturers with strong competitiveness in the market. The average price is half cheaper than imported equipment, which is the reason why domestic coal machinery manufacturers can get sufficient orders in China. At the same time, China's coal machinery procts and manufacturers also have certain advantages over similar international companies in providing high-quality and perfect after-sales service, in-depth and detailed understanding of local customers' needs, and in the price and sales of accessories< br />5、 Ranking of domestic roadheader manufacturers
