What is the material of aluminum alloy?

Today, people are increasingly demanding low-carbon environmental protection, aluminum alloy has become a substitute for many metals, its low density, high strength, easy processing and other advantages, more and more applications in automobiles, high-speed rail, aviation, ships The wider it is, the aluminum alloy will definitely make a greater contribution to human development.

How to distinguish the quality of bearings?

The so-called chamfer of the bearing, that is, the intersection of the horizontal and vertical surfaces. Due to the production technology limitations, counterfeit bearing products are not handled satisfactorily at these corners. We can easily Identify.

666! The principle of simplicity and the magic number 6

Unless we consciously change our thinking and behavior, how to simplify complex things will be an eternal challenge. As Steve Jobs said: “Simple may be harder than complex: you have to work hard to make your thinking clear and keep it simple. But in the end it is still worth it, because once you do this, you can create miracles.”

Why the bolts “If it doesn’t loose, it will break as soon as it looses.”

When the bolt is broken, the easiest conclusion that people can draw is that the strength is not enough, so most of them adopt the method of increasing the strength level of the bolt diameter. This method can increase the pre-tightening force of the bolts, and the frictional force has also been increased. Of course, the anti-loosening effect can also be improved, but this method is actually a non-professional method, its investment is too large, and the benefits are too small.

Motor selection parameters, principles and methods

When the motor is running under load, the total internal loss is converted into heat energy to increase the temperature of the motor. The poor heat resistance in the motor is the insulating material. If the load of the motor is too large and the loss is too large to make the temperature exceed the allowable limit of the insulating material, the life of the insulating material will be shortened sharply.

The rise and development of robots in China

China is in an important position in the international manufacturing industry, manufacturing technology is facing upgrade, and economic development is facing transformation. The increase in labor costs has made robot technology an important development opportunity in China, but the demand for robots in turn has put forward higher requirements for computer-related scientific research.

Why is it difficult to achieve “de-Chinese”?

At present, the issue of “de-globalization”, which is hotly debated by Chinese public opinion, is largely related to the issue of “decoupling” or “de-sinicization” of the West and China. Many people expressed concern about “de-globalization”, in fact they are worried about the negative impact of “de-sinicization” on China’s own interests, and such concerns are not unreasonable.

Mechanical seal maintenance program under special working conditions

Mechanical seals have become one of the most common forms of sealing in motorized equipment in oil refining and chemical installations. Moreover, with the continuous improvement of their design and manufacturing level and the continuous development of new materials, their application scope will be further expanded.
