Hydraulic tube appropriately join one or more alloying elements on the basis of high-quality carbon structural steel, used to improve the strength of steel, toughness and hardenability performance. Type of steel made, usually quenched and shall be subject to the chemical heat treatment, surface hardening heat treatment. Compared with the high-quality carbon structural steel has good mechanical properties, and more rolled into round, square, flat shape of the steel, is used as an important structural parts of machinery or machine. Hydraulic pipe rust than stainless. But the wear resistance, cutting resistance than stainless steel is much better.
The advantages of the hydraulic tube compared with mechanical transmission, electric drive, hydraulic drive has the following advantages:
1, the various components of the hydraulic drive, can easily and flexibly arranged.
2, light weight, small size, small movement inertia, fast response.
Manipulation convenient control, can achieve a wide range of stepless speed (the speed range of 2000:1).
4, automatic overload protection.
Generally use mineral oil as the working medium, the relative movement of the surface can be self-lubrication, long service life.
6, it is easy to achieve linear motion.
7, it is easy to achieve automation of the machine, when the electro-hydraulic joint control, not only to achieve a higher degree of automatic control process, and can achieve remote control.
The disadvantage of the hydraulic tube
1, due to the greater resistance to the flow and leakage of fluid, so the efficiency is low. If not handled properly, leaked not only contaminated sites, but also may cause a fire and explosion.
Work performance are vulnerable to the effects of temperature changes, it is not appropriate to work in high or low temperature conditions.
3, hydraulic components of high precision manufacturing, and therefore more expensive.
4, due to leakage of the liquid medium and compressibility effects can not be obtained the strict transmission ratio.
5, hydraulic transmission failure is not easy to find out why; higher level of technology use and maintenance requirements.
