With the rapid development of my country's hydraulic pipe market, the application and research and development of core production technologies related to it will surely become the focus of attention of enterprises in the industry. Understanding the research and development trends, process equipment, technology applications and trends of domestic and foreign hydraulic pipe production core technologies is very important for enterprises to improve product technical specifications and market competitiveness.
For hydraulic pipes is listed separately because of the five major elements (carbon C, silicon Si, manganese Mn, phosphorus P, sulfur S). The carbon content is between 0.24-0.32%, and the silicon-manganese content is about 1.10-1.40%.
Application of hydraulic pipe
Various alloy pipes:DIN2391 ST52 Cold Drawn Seamless Steel Pipe, 27SiMn Alloy Seamless Steel Pipe, 35CrMo Hot Rolled Seamless Alloy Steel Tube/Pipe,40Cr Alloy Seamless Steel pipe,15CrMo Seamless Alloy Steel Pipe/Tube are divided into seamless steel pipes and welded pipes according to different production processes. Seamless steel pipe is a seamless steel pipe made by piercing steel ingots, tube blanks or steel rods.
Advantages and disadvantages of hydraulic
Advantages of hydraulics
Compared with mechanical transmission and electric transmission, hydraulic transmission has the following advantages:
1. Various components of hydraulic transmission can be conveniently and flexibly arranged according to needs.
2. Light weight, small size, small motion inertia and fast response.
3. It is easy to operate and control, and can realize a wide range of stepless speed regulation (speed regulation range up to 2000:1).
4. It can realize overload protection automatically.
5. Mineral oil is generally used as the working medium, and the relative moving surface can be lubricated by itself, and the service life is long;
6. It is easy to realize linear motion/
7. It is easy to realize the automation of the machine. When the electro-hydraulic joint control is adopted, not only a higher degree of automatic control process can be realized, but also remote control can be realized.
Disadvantages of hydraulics
1. Due to the large resistance and leakage of fluid flow, the efficiency is low. If not handled properly, the leakage will not only pollute the site, but may also cause fire and explosion accidents.
2. Since the working performance is easily affected by temperature changes, it is not suitable to work under very high or low temperature conditions.
3. The manufacturing precision of hydraulic components is high, so the price is relatively expensive.
4. Due to the leakage of the liquid medium and the influence of compressibility, a strict transmission ratio cannot be obtained.
5. It is not easy to find out the reason when the hydraulic transmission fails; the use and maintenance require a high technical level.
