(Belgium steel mill cylinder,produced by Hengyu Hydraulic Co., Ltd）

steel mill cylinder are widely used in Belgium，because of excellent fatigue and impact resistance，no need for deceleration device，long service life.So our company has designed steel mill cylinder for customers from Belgium.

Introduction to steel mill cylinder:

When installing the steel mill cylinder, the axial ends of the steel mill cylinder cannot be fixed. Due to the effect of liquid pressure and thermal expansion in the steel mill cylinder, there is axial expansion. If the two ends of the steel mill cylinder are fixed, all parts of the steel mill cylinder will be deformed. When disassembling the steel mill cylinder, it is strictly forbidden to hammer the steel mill cylinder and the piston surface, such as the steel mill cylinder hole and the piston surface is damaged, do not allow sandpaper grinding, to use a fine oil stone carefully grinding. The clearance between the guide sleeve and the piston rod should meet the requirements.

When the steel mill cylinder is installed on the main engine, the oil port piping part and the guide sleeve should be checked for oil leakage in the running test, and the earring and the middle hinge shaft bearing should be refueled.

When purchasing the steel mill cylinder, try to clarify the following parameters of the steel mill cylinder: A. steel mill cylinder diameter, rod diameter, stroke; B. Working pressure or steel mill cylinder load; C. Working environment temperature; D. Working medium; E. Operating speed; F. Other parameters, such as connection form, mounting size, etc. In this way, the right steel mill cylinder type can be found accurately and quickly.

Before purchasing the steel mill cylinder, it is necessary to master the original information and design basis, mainly including: the use and working conditions of the machine; The structural characteristics, load conditions, stroke size and operation requirements of the working mechanism; The selected working pressure and flow of the hydraulic system; The reality of materials, fittings and processes; Relevant national standards and technical specifications, etc.

Answers to some questions about steel mill cylinder:

What is the cause of the deep scratch of the cylinder?
The following reasons can cause the cylinder to be scratched. 1: Hydraulic oil containing particulate impurities into the hydraulic cylinder, these particulate impurities stuck between the piston rod and the guide ring (or stuck between the piston and the inner wall of the cylinder), when the piston movement in the cylinder will scratch the piston rod, the phenomenon of the inner wall of the cylinder, the more particles, the larger the scratch marks the deeper and more obvious. 2: The body of the cylinder itself. Due to assembly or design reasons, the coaxial error between the piston rod, piston, cylinder, guide ring and other parts is too large, or the cylinder, piston rod straightness error is too large, so that the piston rod and the guide ring interference between the cylinder, this mechanical interference will certainly lose the piston rod or cylinder wall.

What is the thin cylinder used for?
The principle is no different from ordinary cylinders, that is, the installation space is small, the formation is small, and it is suitable for some special occasions. For example, the space is compact and the place of small travel is used.
