Hydraulic support pipe, the implementation of standard GB/T17396-1998. Mainly used to make coal mine hydraulic supports and cylinders, columns, and other hydraulic cylinders and columns.
The hydraulic support pipe represents materials of 20, 45, 27SiMn and the like.
The hydraulic prop pipe is based on high-quality carbon structural steel, and one or more alloying elements are appropriately added to improve the strength, toughness and hardenability of the steel. After being made of such steel, it is usually subjected to heat treatment such as quenching and tempering, chemical heat treatment and surface hardening. Compared with high-quality carbon structural steel, it has good comprehensive mechanical properties and is rolled into round, square and flat steels, which are used as important structural parts in machinery or machinery.
The hydraulic struts are less resistant to rust than stainless steel. However, wear resistance and machinability are much better than stainless steel.
Advantages of hydraulic strut tube
Compared with mechanical transmission and electric transmission, hydraulic transmission has the following advantages:
1. Various components of hydraulic transmission can be arranged conveniently and flexibly according to needs.
2. Light weight, small volume, small motion inertia and fast reaction speed.
3, convenient control and control, can achieve a wide range of stepless speed regulation (speed range up to 2000:1).
4, can automatically achieve overload protection.
5. Generally, mineral oil is used as the working medium, and the relative moving surface can be self-lubricated and has a long service life;
6, it is easy to achieve linear motion /
