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

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

Introduction to steel mill cylinder:

If the steel mill cylinder slips or crawls, please check whether there is astringency inside the steel mill cylinder, because the internal parts of the steel mill cylinder are improperly assembled, the parts are deformed, worn or the shape and position tolerance is excessive, the action resistance is too large, so that the piston speed of the steel mill cylinder changes with the different stroke position, and the slip or crawl occurs. Most of the reasons are due to poor assembly quality of parts, surface scars or sintered iron filings, so that the resistance increases, the speed decreases. For example, the piston is different from the piston rod or the piston rod is bent, the steel mill cylinder or the piston rod is offset from the mounting position of the guide rail, and the sealing ring is too tight or too loose. The solution is to repair or adjust, replace damaged parts and remove iron filings.

When the steel mill cylinder thrust is insufficient, check the hydraulic circuit for leaks. Including leakage of valves and hydraulic lines. The inspection method is to check and eliminate the leakage of the hydraulic connection line by manipulating the reversing valve. Also consider the relief valve. If the relief valve enters the dirt and jams the spool, so that the relief valve is normally open, the hydraulic oil will flow directly back to the tank through the relief valve bypass, resulting in no oil in the steel mill cylinder. If the load is too large, although the regulating pressure of the relief valve has reached the maximum rating, the steel mill cylinder still cannot get the thrust required for continuous action without action. If the regulating pressure is low, the pressure is insufficient to achieve the required vertebra force, which is manifested as insufficient thrust. Check and adjust the relief valve at this time.

Causes and countermeasures of oil steel mill cylinder leakage: Cast iron ring seal allows a certain degree of internal leakage. The impurities in the steel mill cylinder will lead to premature wear of the piston seal, replace the piston seal; If the steel mill cylinder is visibly scarred, the steel mill cylinder must be replaced. It can be pressurized at one end of the steel mill cylinder and opened at the other end of the oil port to observe whether there is obvious internal leakage at the end of the oil port. Most steel mill cylinder piston drift may not come from the steel mill cylinder, the above method to determine the steel mill cylinder without internal leakage is helpful to determine the problem of the hydraulic system related components.

steel mill cylinder hydraulic oil selection: The recommended working oil viscosity of the steel mill cylinder is 10 ~ 110cSt (1.8 ~ 15E), ISO VG46 hydraulic oil. The normal working oil temperature is 10 ~ 70℃, and the ambient temperature is in the range of -20 ~ 80℃. When the ambient temperature and service temperature are low, the hydraulic oil with lower viscosity can be selected.

Answers to some questions about steel mill cylinder:

Can the hydraulic oil in the cylinder return to the tank?
Yes, there is a way, for example, first remove the cylinder from the machine, and then connect the two pipes on the cylinder, so that the cylinder piston rod is completely retracted into the cylinder, at this time, the piston is with the bottom, and the rear chamber is almost no oil, and then screw off the joint at the end of the front chamber by the hydraulic station, and put it in an empty bucket. Finally, insert the gas pipe into the oil port of the rear chamber. Open the air source, and then the rod will run out, and you'll drain the hydraulic oil from the end of the rod, which requires a source of air on site.

How many kilograms can the 63 cylinder hold?
The force of the cylinder is related to the cylinder diameter and pressure. 63 cylinder diameter (cylinder inner circle diameter), 21MPA pressure, thrust 6 tons.
