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

steel mill cylinder are widely used in Romania，because of long service life，smooth movement，high work efficiency.So our company has designed steel mill cylinder for customers from Romania.

Introduction to steel mill cylinder:

Factors that should be considered when selecting the oil seal in the steel mill cylinder: some specific factors should be taken into account when selecting the oil seal in the steel mill cylinder, so as to have correct consideration and get accurate results, and then avoid wrong selection. The factors and aspects that should be taken into account are eight: steel mill cylinder diameter, piston rod diameter, piston rod and piston groove size, steel mill cylinder working pressure, steel mill cylinder movement speed, hydraulic system oil temperature and steel mill cylinder working environment.

steel mill cylinder head explanation: low pressure castings, medium and low pressure with HT300 gray iron, medium and high pressure with 35, 45 steel. When the steel mill cylinder head itself is the guide sleeve of the piston rod, the steel mill cylinder head is best cast iron. At the same time, brass, bronze or other wear-resistant materials should be fused on the guide surface. If the guide sleeve is pressed into the steel mill cylinder head, the guide sleeve shall be wear-resistant cast iron, bronze or brass.

The pressure, temperature, medium and speed of different types of seals are not the same, water-ethylene glycol medium (HFC) can not be sealed with polyurethane, it can only use rubber seal; When the steel mill cylinder is running fast, it must be sealed with slip ring, such as Sterseal, Glairing, GD1000K, TDI, etc., when the running speed is slow, Yx, U, V combination seals can be used; Fluorine rubber seal is used in high temperature and high pressure environment; When the running speed is fast, the buffer sleeve and buffer valve must be considered.

In the case of serious wear on the inner surface of the steel mill cylinder, or when there is a deep longitudinal tensile mark, it should be mapped according to the physical object and re-produced by the professional manufacturer according to the steel mill cylinder manufacturing process for replacement. The steel mill cylinder can also be repaired with TS311 antiwear repair agent. TS311 anti-wear repair agent is mainly used for the repair of worn and slipped metal parts.

Answers to some questions about steel mill cylinder:

When does the cylinder rotate?
The piston rod inside the multistage plunger cylinder can be rotated, and it will rotate when it is subjected to tangential force.

How to remove the air in hydraulic cylinder?
Connected the cylinder to the system, and reciprocating move with full stroke several times, then the air can be eliminated . There is also a clunky method as follows: first remove the rod cavity oil pipe, connect the rodless cavity oil circuit to extend all the cylinders, and then remove the rodless cavity oil pipe, connect the rod cavity oil pipe and withdraw all the cylinders, and then connect the rodless cavity oil pipe, so that there is no air in the cylinder.
