Preface.

The electricity bill alone is 1,500 yuan higher, and it cannot be used at any time; If there is a power outage, it is a loss of millions. Every power outage causes incalculable damage.

What's wrong with a computer that runs 365 days a year and breaks down when it stops? What secrets are hidden in this?

Glass manufacturing plant.

The glass factory is a factory that works 24 hours a week, 365 days and nights a year. In order to continue working, there must be enough machinery and enough temperature to keep the plant running.

Glass is a very fine material, and its hardness and durability are affected by high temperatures. Its manufacturing process is complex and the temperature is also high, requiring all the ingredients to be mixed together and then put in a container that melts it into a liquid without bubbles at a high temperature. If during this period, the machinery is shut down and the temperature is below 1,000 degrees, the material cannot be fully melted, causing mechanical failure.

When the power is cut off, it not only affects the melting of the glass, but also cools it down. After the glass becomes a gasless glass liquid, and then converted from a liquid state to a solid material, this stage must be heat treated, and the heating cannot be stopped immediately, otherwise it will occur in storage, transportation or use**. Heat treatment simply lowers the temperature to an acceptable temperature range and does not completely shut down the equipment to maintain the strength and durability of the product.

The manufacture of glass products is a very cumbersome process, and some other materials are added when melting, such as the tempered glass of mobile phones, which are cooled step by step after formation, which are all used by machines. Even if each process is tightly controlled by machinery, there is still a possibility of defective products, not to mention stopping the production line, even if the production line is stopped, it will greatly reduce the production capacity behind it, and even affect the quality of the product.

Ford established the world's first glass production line in 1913, setting a new record that no one has ever surpassed. There was once a metaphor that said that there was a legless bird living in this glass factory, and it could not stop flying together, and if it fell, it would be a dead end. The same is true for this glass factory, where even if something happens, it can't stop the machine.

In addition, the equipment in the factory is very complex and requires specialized personnel to maintain it, and if something goes wrong, it is very likely that the equipment will not work properly. If we want to get it back to normal and make more glass, it's to open another factory. In many glass factories, the doors are not closed, even if they are not instructed to do so, and there are usually special personnel who regularly check the equipment, which is the most important job of any glass factory.

Magnetic resonance imaging machine.

The hospital purchased a set of medical equipment worth tens of millions of dollars, but this alone costs more than 15 million yuan for electricity alone, and more than 500,000 yuan in a year. Such a high-power device cannot be shut down at any time, and it costs 600,000 yuan every time it is shut down. Why can't the MRI be turned off?

This is a very expensive piece of equipment, which is not only expensive, but also very expensive to repair. The basic idea is to apply a strong magnetic field in the instrument to cause multiple nuclei in the sample to resonate at the same time, and then obtain information about the structure and properties of the material. Therefore, when the magnetic field in the instrument is stronger, a stronger resonance signal is obtained. In order to maintain a high-intensity magnetic field at all times, 2000 liters of liquid helium must be injected into it and excited again.

After a period of continuous operation, if there is a failure or other reasons, it must be shut down and magnetized, which is very costly. After the power is off, not all the magnetic force can be canceled out, but it takes a lot of energy to slowly weaken its magnetic force, so if the power is cut off, its magnetic field cannot be well dispersed, which will cause damage to the instrument.

MRI is a high-precision instrument with high precision, high sensitivity and high stability, which is the key to achieving high precision, high sensitivity and high stability. It is expensive due to the need for specialized overhaul and commissioning work, and when the power is lost, the original parts of the instrument are damaged, and it also causes current waves that can damage the electronics.

In order to keep the plant running, he had to buy more liquid oxygen. At present, although there is a small amount of helium reserves in China, the supply of helium in China and the world is seriously insufficient, which has brought great pressure to the country. Now, not only medicine, but many industries, including scientific research, and other industries, require large quantities of helium, which is far beyond our production capacity.

However, the United States, for various reasons, has imposed strict controls on our helium exports. If all the equipment stops working and there is not enough helium, these equipment will become a pile of scrap metal, which will bring tens of thousands of economic losses to the hospital every day.

Very low temperature freezer.

At Rensselaer Tech University in New York, a janitor cut off a freezer in the United States because he thought his lab equipment was making a lot of noise. The lab was indeed peaceful, but the impact was enormous. For this reason, the school took the cleaning company to court because the cleaning staff lacked professional knowledge and neglected management, resulting in the destruction of 25 years of scientific research and the economic loss of at least $1 million.

This freezer is different from ordinary freezers in that it is used to store various biological samples at a temperature of -44 degrees Celsius. At that time, he was told that the refrigerator was broken, and there was a sign on it that explained why it was so loud and how to turn it off.

But it was clear that the cleaner ignored the warning, causing his research to fail. Schools are furious about this, arguing that it could cost as much as a million dollars to restart the project. This is not the first time this has happened, in 2012, a scientist working on autism died on a refrigerator.

At that time, an ultra-low temperature freezer for brain samples was broken, and it was only -79 degrees Celsius, but it was minus 79 degrees Celsius inside. As a result, more than 100 frozen brain samples were melted and began to decay. Among these samples, 54 were donated by people with autism, which made scientists feel very sad, because this accident has left autism research more than a decade behind.

Because this kind of thing is common in major universities in China, it is not uncommon for this situation to occur, and once the sample is damaged, it is a very serious matter. This is the biggest taboo in research, and one mistake can cause huge losses.
