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

steel mill cylinder are widely used in Luxembourg，because of smooth movement，high work efficiency，excellent fatigue and impact resistance.So our company has designed steel mill cylinder for customers from Luxembourg.

Introduction to steel mill cylinder:

The steel mill cylinder should be used as far as possible to avoid the transverse force, sometimes the piston rod to bear the transverse load is too large, especially do not force or pull the steel mill cylinder, bite. Elimination method: When installing the steel mill cylinder, ensure that the axis position of the steel mill cylinder is consistent with the direction of movement; Make the load borne by the steel mill cylinder as far as possible through the steel mill cylinder axis, to avoid the phenomenon of eccentricity.

The steel mill cylinder is mainly composed of body, piston, piston rod, steel mill cylinder head, steel mill cylinder bottom, piston rod head and related auxiliary devices. The piston divides the steel mill cylinder into two chambers, and moves reciprocally in the steel mill cylinder with the help of pressure oil. In order to improve its working effect, there is no sealing ring on the piston to eliminate internal leakage, where the piston rod passes through the steel mill cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the steel mill cylinder through the gap, so the sealing device and dust prevention reason are set. At the same time, in order to eliminate the influence of eccentric load on the work of the piston, all the steel mill cylinders must be provided with a considerable length of guide sleeve at the extended end of the piston rod. In addition, in the case of faster piston movement, the phenomenon of mechanical collision between the piston and the steel mill cylinder bottom and the steel mill cylinder head is serious, so the buffer deceleration should be set at both ends of the steel mill cylinder The working medium of the steel mill cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; steel mill cylinder sealing device: The use of Yx sealing ring, polyurethane (PU) and polytetrafluoroethylene (PTFE) materials combined to achieve a good sealing effect; Buffer mechanism of the steel mill cylinder: The buffer structure of the steel mill cylinder is to prevent the piston from colliding with the steel mill cylinder head at the end of the stroke.

steel mill cylinder piston sealing is best to use Yx ring, polyurethane and polytetrafluoroethylene sealing material combination, can significantly improve the sealing performance: (I), reduce friction resistance, no crawling phenomenon; (ii) Have good dynamic and static sealing, wear resistance, long service life; (iii) The installation groove is simple, and the disassembly is simple.

In order to ensure the service life of the steel mill cylinder, the hydraulic system must be set up effective filtration to prevent pollution, the cleanliness of the oil should meet the ISO4406 standard, and the quality of the filtration should also meet the corresponding standards in ISO. The grade requirements of the filter are performed according to the actual working conditions of the system, but the minimum requirements are not less than 19/15 in ISO4406, that is, 24μ (β10≥75) in ISO4572.

Answers to some questions about steel mill cylinder:

How to remove the cylinder correctly?
(1) Before disassembling the hydraulic cylinder, the hydraulic circuit should be depressurized. Otherwise, when the tubing joint connected with the cylinder is loosened, the high-pressure oil in the circuit will be quickly ejected. The hydraulic circuit of the hydraulic press should first loosen the hand wheel or pressure regulator screw at the relief valve, so that the pressure oil is unloaded, and then block the power supply or block the power source to stop the operation of the hydraulic equipment. (2) When disassembling, it should prevent damage to the top thread of the piston rod, the oil thread, the appearance of the piston rod, the inner wall of the cylinder liner, etc. In order to prevent the piston rod and other slender parts from twisting or deformation, the use of cushion wood support balance when placed. (3) Disassemble in order.

How to judge the leakage in the cylinder?
Common judgment method: In the production site, people make full use of watching, listening, smelling, touching and other sensory ways, by observing that the cylinder can not move or delay the action or feel the oil temperature change, vibration and noise, etc., and then judge whether the cylinder has internal leakage according to experience. Another method commonly used in the field is to extend the cylinder in place to ensure that the cylinder does not have any load and will not retract (to prevent the cylinder from internal leakage accidents), turn off the machine, and then remove the tubing with the rod cavity, and then press the switch that pulls out the cylinder (do not press the wrong switch). If the oil nozzle with the rod cavity drains the cylinder internally, If there's no oil coming out, you have to think about something else going wrong.
