What is the difference between crystalline and amorphous plastics?
(1) Crystalline is a solid in which the internal particles (molecules, atoms, ions) of minerals are arranged regularly to form a certain lattice structure, which is called crystalline (crystal). The result of the regular arrangement…
What are the commonly used die steels? What are the differences between different steels?
What is the difference between NAK80 and S136? What are the characteristics of NAK80? If the mold core uses H13, what material is used for the inclined top, and why? Commonly used die steel: P20,…
Why do steam pipes need a pressure reducing valve for pressure reduction?
When the steam is output from the boiler at high pressure and then sent to the steam point of each equipment, the pressure reduction control is usually carried out. Why does steam need to be decompressed?…
How many types of seals are there on construction machinery? What are they used for?
Construction machinery is inseparable from the oil cylinder, and the oil cylinder cannot be separated from the seal. A common seal is a sealing ring, also called an oil seal, which acts as a barrier against…
Design steps and design requirements of hydraulic system
The hydraulic transmission system is an integral part of hydraulic machinery, and the design of the hydraulic transmission system should be carried out simultaneously with the overall design of the main engine. When starting the design,…
Common metal material hardness comparison table
Hardness refers to the ability of a material to resist local deformation, especially plastic deformation, indentation or scratches. It is a measure of material softness and hardness. The comparison table of Vickers hardness, Brinell hardness, and Rockwell hardness is shared with you.Collect it now!
What exactly can finite element analysis do?
Today, the editor will give you a popular science of finite element, finite element simulation, and finite element analysis. As the saying goes, interlacing is like a mountain. If you don’t try it in the…
Introduction and comparison of several major finite element software
1. Introduction to finite element method The finite element method (Finite Element Method, FEM for short), as a powerful numerical calculation method, is the greatest advancement in computational mechanics in the past fifty years. Its appearance…

Advantages of tolerance design and calculation examples
Is it designed based on KKD (experience, intuition and courage) alone? Explain the advantages and necessary knowledge of tolerance design concisely and easily!
Four transmission methods (mechanical, electrical, hydraulic and pneumatic), Which is the king of transmission?
There are many transmission modes. Among the four major types of transmission methods (mechanical, electrical, hydraulic, and pneumatic) that are currently widely used, none of the power transmissions is perfect. Today I will share with you the comparison of the pros and cons of the 4 transmission methods.
What is Diaphragm Compressor?
The diaphragm compressor is determined by its structural characteristics. It is widely used to compress and transport various high-purity gases, precious and rare gases, toxic and harmful gases and corrosive gases. As an irreplaceable positive displacement compressor, it will follow the progress and development of science and technology and the people’s living standards.
Understand strength and stiffness in material mechanics
Stability is well understood, the ability to maintain or restore the original balance form under force. For example, the thin rod under pressure suddenly bends, the load-bearing thin-walled member folds, or the column of a building collapses. Today I will mainly talk about the understanding of stiffness and strength.
Talk about our mechanical engineers under the epidemic
When I came into contact with people in 96 and 97, I was generally interested in electricity. Many of my friends are also learning and don’t want to work on machinery alone. But this is also a disadvantage. It feels bad for people and feels not doing business properly. The roots of machinery are not well established. But 96 and 97 have strong learning ability, after all, they are young people.
