Reasons for sudden power failure of mining machine

1. To be honest, I may come into contact with bitcoin later than many of my peers, but I'm one of the quickest people to make a decision to join the instry. I learned from the news that Jet Li's one foundation was grateful to the enthusiasts who donated bitcoin. After less than ten minutes of thinking, I immediately decided to put down 90% of the projects I had completed and devote myself to this instry with incomparable prospects. I am a technology controller. Although I am not well-known in the Internet instry, I have operated no less than 10 it projects, and have cooperated with or established 7 companies. Among them, there are also successes and failures. The only instry that has not been involved is group buying, because I thought from the beginning that group buying deviated from its original appearance and would not be a very promising instry. But after learning about bitcoin, I feel that I have found a window, a window to the palace of ideals, a way to change the world. Today, I still insist on my choice, but the real use value of bitcoin in China is rarely reflected except for its speculative property. After multi-party analysis, I think the short-term downward trend is irreversible. Let's list the following factors that cause the price of bitcoin to fall:
first, the excessively free market - the copper price killer
bitcoin is born for freedom and lives for freedom, which has created a group of bitcoin fans who are crazy about pursuing freedom. The decentralization of the bitcoin exchange has been rampant for a time. The current situation of no supervision of the bitcoin exchange is obvious to all, and it can not be solved by itself, such as the forever anonymous dark village, the disorderly competition of mining machinery, etc. these important factors that are often ignored by people are also important drivers of the price drop
just think of the capitalist social system in the early days. People had great expectations and perseverance. They could sacrifice their lives for freedom and cut the rope on puppets at all costs. During the transition from feudal socialism to capitalism, people were like holding on to the water for several generations, suddenly came out to breathe fresh air, and no one was allowed to press themselves into the water again, The result is a social system of excessive freedom. The result of excessive freedom is that once someone obtains certain resources and social advantages, he can quickly devour everything around him like a black hole, forming a monopoly and giving birth to an oligarchy. They don't care about other people's lives, just like gladiators. If you lose, you have to bear all the consequences; If I win, I can enjoy some honor. But after all, oligarchs are a minority. Society is made up of thousands of ordinary people, so the system made up of people must be unstable and unreasonable. Therefore, modern capitalist society has learned to compromise. After learning from many advantages of capitalist society at that time, it is found that there are anti-monopoly laws, various anti-commercial bribery and other daily laws for proper supervision, In order to effectively delay the outbreak cycle of the financial crisis
the reason why so many words are used to describe capitalist society is that bitcoin has too many similarities with it. A brand new financial system does not depend on specific institutions or indivials, but also depends on all participants. With it, we can eliminate all external influences and keep our wallets. It's a great idea, but what about the reality? Holding a large amount of bitcoin, amzhuang can control the price of bitcoin. In the capital market, 1 billion yuan is only a very small amount. For the bitcoin market, it is enough to control the price rise and fall of any exchange, back and forth volatility, commonly known as "fleece". Easier said than done, as like as two peas in the market, you will be able to control the bitcoin in your hands. But you have to be in the market. For these makers, they can benefit from the ups and downs, because in the trend of the rising market, they will increase ring each shock period, and fall more every time the market falls. At the top of the pyramid, there are always only a few people
after more than a year of communication with players in the instry, we found that those who are still left behind are either deeply covered or persistent believers. Even if they are covered, only a few of them are entities. Most of the left behind are pure it houses, and they blush when they meet. Most of them have no financial experience, even few of them have speculated in stocks, so they are in shock, It's certain that Xiaosan will be injured< Another important factor is that, like stocks, the amount of cash in circulation is far less than the total value. Although several exchanges have not announced the amount of bitcoin and the total amount of RMB assets, it can be concluded from the data of mtgox's bankruptcy that the amount of cash announced by mtgox is US $40 million, Bitcoin is worth US $450 million, reaching a staggering 1:11. According to my preliminary understanding, the general comparison of domestic trading platforms is between 1:3 and 1:6, which is slightly better than mtfox, but it is also enough to illustrate the problem. Once the bear market comes, the power of shorting is far greater than that of long
although the stock market did not rise sharply last year, many people did profit from the stock market and attracted many of the few users who swayed between the stock market and bitcoin. Many of the professional investment users and deep-seated users who benefited from bitcoin also left the bitcoin instry for various reasons. The big reason is that for bitcoin, They think that in addition to speculation, it is a game played by technical talents. Although this is a misunderstanding, let's think about it from another perspective. If you are an investor outside the IT instry and face the world's largest trading platform, you will go bankrupt if it goes bankrupt. If bitcoin is stolen, it will be stolen without supervision and responsibility. What would you think? Therefore, the reason for today's situation is that the number of bitcoin has not decreased, but the capital is decreasing. Although there are many foreign advantages ring this period, the domestic situation has been declining. This is an indisputable fact
with the decrease of funds, long has lost enough momentum. The reason why there is no sharp decline is that there are still a number of bitcoin loyalists. Some of them have been engaged in bitcoin for several consecutive years, and almost every year they have to experience a similar slump. Therefore, they still firmly believe that this year is just a repetition of the market rules of previous years, and the final price will rise; Of course, I personally believe that in the long run, the trend of bitcoin will go up, but is it half a year or three to five years? I'm really not sure, because the biggest constant in the world is change. As the saying goes, the flowers are similar year by year, but the people are different year by year. The past experience may not be applicable to the present< Third, domestic policy - gold price killer
I don't know if the Americans have understood that it was not Japan, the United States, Europe, but China that decided the price of bitcoin in 2013. Made in China used to be a headache for foreigners. Now, they also realize the power of China's speculation. China's real estate speculators are like locusts everywhere they go. At present, China's speculators are also rapidly overdrawn the growth value of bitcoin. China, which has 80% of the world's trading volume, explicitly forbids the value of bitcoin as a medium of exchange, so it has no real value in China except for speculation
I believe that the world's understanding of the power of Chinese speculators in bitcoin began with the documents of five ministries and commissions, because before that, almost no organization participated in the international bitcoin conference. After that, many foreign media swarmed in, professional and unprofessional media came. This time, although the documents on April 15 have not been confirmed, the financial times interviewed bitcoin in advance, which shows that they recognize the power of Chinese speculators
why is an Internet proct that started in foreign countries so influenced by China's policies? This is not its main application place, which just reflects that the price of bitcoin is seriously out of its actual value line, artificially pushed up and overdrawn its value. In my opinion, without CCTV's report and China's participation, it would have been good for bitcoin to have a price of more than 1000 last year. It was also e to excessive attention, which created the fastest five ministerial documents in history< 4. Crazy miner - the ultimate price killer
the computing power of bitcoin miner has increased from 1p at the end of last year to more than 30p now. In less than five months, the price of bitcoin miner has dropped from 6000 to 2700 today. In other words, the number of miner has increased dozens of times, from CPU to motherboard, power supply, power supply, etc The chassis and processing costs are all paid in RMB. Just imagine how much cash flow the mining machine has taken from the whole bitcoin ecological chain. Once the cash flows into the hands of TSMC, motherboard factory and others, it will never be kept back. This is also the result of disorderly competition, once profitable, the number will never end! It is said that Shenzhen proces 90% of the world's computing power of mining machines, and each time the chips are streamed, the chips are less than 3.5 million, more than 20.3 million, not to mention the whole machine. A mining machine manufacturer I know in Shenzhen club said that he sold 1000 USB mining machines a minute, which shows the madness
to sum up, all aspects have exerted pressure on cash flow, so the continuous decline of bitcoin in the short term is caused by many reasons. Even without the 4.15 document, I believe a continuous decline process will be formed. As for the bottom, it depends on the belief of those who still hold fast to it and when the crazy mining machine will not continue, And the actual application of bitcoin in foreign countries
those who played with stocks in 2008 may find that bitcoin shares a striking resemblance to the price trend of stocks. If bitcoin goes up from 2000 to 5300, any good news, even an additional issue, will make stocks soar all the time. After that, although the stock surged to the highest point, the downward trend was like "defeat like a mountain". Any bad news would cause a decline. Coupled with the excessive issuance of new shares and serious overdraft of market cash, the a share once fell back to about 1600 points. Although it rebounded to more than 3000 points, it would still jump to about 2000 points. After several years of shock, it did not improve
bitcoin plate is small and easy to rise and fall. However, if the retail investors are excessively injured, bitcoin's loyalty can only be powerless to let bitcoin rise. The false rise of the makers will face a lot of market capital pressure and can only follow the trend
at present, there are several companies in the whole instry that can support short selling, such as fire coin, China bitcoin and okcoin, which also aggravates the dection process
of course, I am still very optimistic about the long-term development of bitcoin, but I really can't see how to break the current deadlock. The purpose of this article is to provide some personal opinions for the majority of small businesses. Maybe you are more in-depth and complete than I think, but finance is nothing more than that

2.

1. Back up important data and photos and restore factory settings. Don't install applications from unknown sources. In addition, don't authorize in permission settings

2. You can swipe the computer to see if it can't work. Besides, the computer needs to clean up the memory on time so that it won't get stuck. The memory of the mobile phone is seriously insufficient. It is recommended to clean up the memory lightly, and then restart your mobile phone again

3. Clear the data of the mobile phone. If there are important things, save them on the network disk first, and then restore the factory settings three times. This is safer

< H2 > extended data:

1. Set the security level of the browser. Our common browsers all have the function of security level setting. Through reasonable setting, we can effectively filter the access restrictions of some illegal websites, so as to rece the damage to computers and personal information

2. Firmly resist reactionary, pornographic and violent websites. On the one hand, these bad information will affect the physical and mental health of teenagers, on the other hand, many illegal websites will use browser vulnerabilities to attack users

3. Don't click illegal links at will

When downloading software and materials, we should choose the regular website or official website

5. Turn off some sensitive functions in common communication software. Such as "people nearby" in wechat and "allowing strangers to view photos" in wechat privacy

6. Do not take photos of your family and address. If it goes on like this for a long time, as long as it is analyzed and summarized by others, the information exposed will become a complete set of information, which hides all kinds of unpredictable risks

Do not test related information on the Internet. Some websites do surveys and ask for information about age, hobbies, gender, etc. to do it for a small profit. This information may be used by others, and graally summarized, and sold to others for profit or threat

3. Common faults and troubleshooting of ball mill
pitting corrosion or melting phenomenon of main bearing e to high temperature may be caused by one of the following reasons:
interruption of lubricating oil or insufficient oil quantity. In case of oil interruption, stop feeding water supply immediately, open the observation hole cover on the bearing, try to approach the hollow journal by hand (pay attention to prevent handle scalding) and check the bearing temperature. If the bearing is not overheated, it can be stopped to deal with the oil circuit fault; If the temperature of the bearing is quite high and the hand is close to the hollow journal and feels hot and smoking, do not stop the machine. Manually pour oil on the bearing to cool it until the temperature of the bearing returns to normal. If the engine is stopped without cooling measures, not only the bearing will not be burned out, but also the hollow shaft and big bearing will lock up
if the lubricating oil is too thick or too thin, it can be eliminated by re selecting the type of lubricating oil; Stop using cooling water or resistance heating
if the oil deteriorates, clean the bearing and oil passing parts and replace the lubricating oil
if the grinding and scraping of the big tile does not meet the requirements, the big tile should be re grinded and scraped to make it meet the technical requirements
impurities such as mineral sand and iron chips fall into the bearing surface, causing damage to the bearing surface and causing marks and grooves on the bearing surface
elimination method: clean the bearing, repair the bearing and journal, if the melting area is large, weld the bearing with welding gun or cast Babbitt alloy again, and change the lubricating oil
there is water in the lubricating oil, which can prevent the formation of oil film and proce cracks and pitting corrosion at local points without oil film
elimination method: clean the bearing and change the lubricating oil
it is difficult to start the mill, the starting current of the motor is large, and there is overload.
causes and elimination methods:
the medium in the mill agglomerates with the ore, and the center of gravity deviates from one side of the cylinder seriously. In this case, when driving the mill, the motor is not enough to overcome the eccentric moment, and cannot drive the mill, resulting in overload
elimination method: open the hole cover, enter the cylinder, turn the medium with a crowbar, and unload part of the medium
the unbalanced three-phase load of motor mainly refers to the unbalanced three-phase current of motor. The rotor of the motor is driven by the electromagnetic torque (i.e. rotating magnetic field) generated by the three-phase power supply passing through the stator winding. When the three-phase current through the stator winding is balanced, the electromagnetic torque generated is also balanced. If a certain phase current is caused by poor contact of conctor joint or leakage, poor winding insulation, etc., the current will be weakened, and the electromagnetic torque generated by this phase current passing through the stator winding will also be reced, so it is difficult for the mill to start and the motor will be overloaded
elimination method: disconnect the motor from the gearbox, start the motor under no load, check the current of each phase with a clamp ammeter, and check the winding of the motor when the current is abnormal, such as checking the insulation with a megger, find out the cause, and then start the motor after treatment
there are ore or steel balls in the feeding box. For closed-circuit grinding, if the ore and steel balls from the bulging belly of the grinding machine are not removed from the feeding box, or after the grinding is stopped, the classifier is not stopped in time, so that the returned sand can be accumulated in the feeding box. When the mill is started, the feeding scoop is blocked, resulting in a large eccentric torque, which causes the motor overload
Troubleshooting: open the treatment hole at the bottom of the feeder box and clean up the ore and steel balls
there is slurry leakage from the connecting bolt of cylinder liner plate
causes: the nut fixing the liner plate is loose, the sealing gasket is damaged, the screw is broken, the liner plate is broken or falls off, etc
Troubleshooting: tighten or replace the bolts, add sealing washer, and replace the liner if necessary
the sound inside the grinding machine is weakened or enhanced
the main reason for the weakening of the sound inside the grinding machine is that the feeding amount is too much, the block is too large, the feeding amount is greater than the discharge amount, and the grinding machine begins to swell
the exclusion method was treated as the exclusion method
the increased sound in the mill may be e to too little feeding, resulting in empty grinding, and the medium directly strikes the liner or the medium strikes each other. When the feeding is normal and the sudden sound intensifies, it is caused by the lining plate or grid plate falling off
elimination method: increase the feeding amount. If the liner falls off, stop the machine immediately to replace or reassemble the liner
the grinding machine suddenly proces strong vibration and impact sound. One of the following reasons will cause the above phenomenon:
iron impurities are mixed in the gear clearance. The elimination method: stop the machine immediately and trim the tooth surface
the pinions move in series in the axial direction and collide with the gearbox. The elimination method: stop immediately, replace the gearbox and fix the gears along the axial direction again
if the gear is damaged, the elimination method is to stop immediately and replace the gear
if the bearing or anchor bolt is loose, the elimination method: first adjust the gear to make the big and small gears mesh correctly, and then tighten the bolt.
