The most powerful blockchain project

1. In 2020, CEG must be the most eye-catching. The radar mode of public chain cash mining interest generating project, radar has gone through six years, but CEG is only three months, at this time has it to embrace wealth.

2. At present, the best choice of blockchain is EHS eBay insurance

the insurance application on the chain based on blockchain, the primary market is free and the secondary market such as Huo coin is assisted by a special management team.

Blockchain is the general trend of the tuyere project, but when choosing blockchain projects, we must shine our eyes and find a team with technology, application and real down-to-earth work. Otherwise, it may come to nothing, because since it is a trend, naturally there are a lot of speculation and fraud projects

here, we mainly introce utispace, the first blockchain distributed storage project with perfect technology and real application in the world

investment highlights

a brief introction to utispace: is 5g coming? Have big data, artificial intelligence, wearable devices, Internet of things and AI entered our lives? Is the phone running out of memory

stuck

the high-speed information flow inevitably needs infinite storage space, but the current storage space is never enough

for example, the storage space of 4G mobile phone determines the price of mobile phone, but what about 5g mobile phone? More to 10 times the demand for 4G space storage, the price will be expensive

where there is demand, there is market. In the past, we need to build a big data storage base station for big data storage. The cost is very high. It costs 10 billion yuan at any time, and the security is very low (the base station will be hot and prone to fire and earthquake, what should we do? If hackers attack all data, they will be paralyzed). In addition, no matter how big the base station is, its storage capacity is limited, and it can never meet the demand of doubling the amount of data generated by the market, resulting in a large number of useful data homeless. At present, 67% of the data has been deleted, which is a great loss

so who can solve the data storage with large storage, high security, low cost and low energy consumption

today, the decentralized distributed storage space of China's own brand utispace, together with the digital pulse chain Laboratory of Zhejiang University, has solved this worldwide problem. Thus, it takes the lead in occupying the big cake of distributed data storage

Air conditioning everyone should know it! It is one of the household appliances, can afford air conditioning, that our living standards have improved a lot, the main role of air conditioning is cooling and heating, with it can ensure the warmth of winter and cool summer. Now there are many brands in the air conditioning market, such as Haier, Gree and other domestic air conditioning brands, you should know! Today, I'd like to introce a brand of air conditioner that we don't know. It's SOI air conditioner. The following small series to give you a detailed introction to some of the specific circumstances of the air conditioning bar

How about SOI air conditioner? Advantages introction

Sony inverter air conditioner is more environmental friendly, more energy-saving and lower noise

first, Sony inverter air conditioner has low voltage requirements and good low-voltage operation performance. In China's third and fourth class market, the trend of expanding the gap of power resources is more and more obvious. In summer, when the air conditioner is used in the peak period, the unstable voltage often occurs, which leads to the damage of the air conditioner. SOI variable frequency air conditioner improves the adaptability of the air conditioner to the voltage. It can be started under the voltage of 160-260v, and can operate with high power. It can reach the set temperature quickly, and maintain the room temperature balance with low power, which solves this problem very well

Second, has good energy saving. The excellent energy saving performance of SOI variable frequency air conditioner is reflected in three aspects. First, it has good starting performance. The compressor of ordinary constant frequency air conditioner starts at constant frequency, and the starting instantaneous current can reach 4-7 times of the normal operating current, which consumes a lot of electric energy. The electrical components of air conditioner also need to be designed according to this current, causing a lot of waste; The soft start is adopted in SOI variable frequency air conditioner, which starts at low speed in low frequency range with small starting current, which can effectively save electric energy and material cost in design. Second, automatic low frequency maintenance. The compressor speed of ordinary constant frequency air conditioner is fixed, and the stable effect of indoor temperature is maintained by starting and stopping the compressor; By using low frequency operation, SOI variable frequency air conditioner can keep the indoor temperature stable and avoid frequent starting of compressor. At the same time, e to the use of electronic expansion valve to adjust the liquid supply at any time, the air conditioner always works in a state of high efficiency. The efficiency ratio is greatly improved, and the power saving effect is very obvious. Compared with the constant frequency air conditioner, the power saving effect is more than 30%, At the same time, because the compressor no longer starts frequently, it also extends the service life of the compressor. Thirdly, R410A environment-friendly refrigerant is used in the air conditioner, which is in line with the EU environmental protection standards. The damage to the ozone layer is almost zero, and the heat exchange effect of the refrigerant is improved, making the air conditioner more energy-saving and environment-friendly in daily use and operation

thirdly, has low noise and good mute effect. The SOI air conditioner with frequency conversion compressor has the advantages of balanced operation, less vibration, 5-10 DB noise rection, less noise interference to human body, and quieter sleep at night

SOI frequency conversion air conditioning is more automatic, more comfortable and room temperature constant

Fourth, SOI frequency conversion air conditioning has higher heat to cold ratio and better low-temperature heating effect. The compressor speed of ordinary constant frequency air conditioner is relatively stable ring refrigeration and heating, so the heat cooling ratio can only be improved through the matching of the system, which has great limitations, generally can only reach 120%; The speed of compressor in heating is much higher than that in cooling, so the heat to cold ratio can reach 140%. With the decrease of outdoor temperature, the heating capacity of ordinary constant frequency air conditioner will decrease obviously. When the outdoor temperature drops below 0 ℃, the heating capacity will basically lose; However, SOI variable frequency air conditioning can increase the heating capacity by high frequency operation in low temperature environment? At 15 ℃, it can still keep good heating capacity through high frequency operation

fifthly, keep room temperature constant. Due to the use of variable frequency compressor, SOI variable frequency air conditioner can automatically adjust the operating frequency of compressor according to the change of room cooling (heating) load. After reaching the indoor set temperature, the inverter air conditioner operates at a lower frequency to avoid discomfort caused by drastic changes in room temperature. When the load is small and the operating frequency is low, the power consumption of the compressor is small, and the frequent start and stop is avoided, so as to save more power

sixth, it has strong automatic load adaptability and fast cooling and heating speed. The cooling capacity of ordinary constant frequency air conditioner will become worse with the increase of heat load. When it is necessary to provide more cooling capacity or heat to the room, the cooling capacity or heating capacity of air conditioner is seriously insufficient, which directly affects people's comfort; The SOI variable frequency air conditioner can automatically adapt to the change of heat load. When the indoor and outdoor temperature difference is large, or the indoor temperature is too different from the set temperature, it will automatically increase the frequency of the compressor power supply, so that the speed of the compressor can be accelerated. With the electronic expansion valve, the refrigerant flow can be automatically adjusted to achieve rapid cooling or heating

10. There are two basic types of milling and digging machine: horizontal milling and digging machine and longitudinal milling and digging machine, that is, digging head
ente roadheader price network "ente heavy instry" can know the basic structure of No.2 Middle School: gear transmission and direct output
the digging head is mainly composed of walking mechanism, working mechanism, loading mechanism and transfer mechanism. As the walking mechanism moves forward, the cutting head in the working mechanism continuously breaks the rock and transports the broken rock away. It has the advantages of safety, high efficiency and good quality, but the cost is large, the structure is complex, and the loss is also large< It can be installed on any type of hydraulic excavator, effectively replacing the general configuration of bucket, breaking hammer, hydraulic shear, etc. it is used in many fields such as open-pit coal mine, tunnel excavation and profile correction, channel trench milling, asphalt concrete pavement milling, rock frozen soil milling, tree root milling, etc, Milling machine provides a new construction method for tunnel excavation.
