(Costa Rica steel mill cylinder,produced by Hengyu Group）

steel mill cylinder are widely used in Costa Rica，because of clever hydraulic energy conversion，simple structure and reliable operation，excellent temperature resistance.So our company has designed steel mill cylinder for customers from Costa Rica.

Introduction to steel mill cylinder:

The internal leakage of the steel mill cylinder is an important indicator to measure the quality of the steel mill cylinder: the internal leakage of the steel mill cylinder will reduce the volumetric efficiency, increase the temperature rise of the oil, affect the positioning accuracy of the steel mill cylinder, so that the steel mill cylinder can not accurately and stably stop in a certain position of the steel mill cylinder, so it is one of the main indicators of the steel mill cylinder.

The assembly work of the steel mill cylinder has a great impact on the quality of the steel mill cylinder: each part must be carefully cleaned before assembly; To correctly install the sealing device everywhere: when installing the sealing ring, pay attention to its installation direction to avoid oil leakage due to installation, and its lip should be equipped with a pressure oil chamber. In addition, because it is a YX-shaped sealing ring, it is necessary to pay attention to distinguish between shaft and hole use, do not install wrong; Because the sealing device is matched with the sliding surface, an appropriate amount of hydraulic oil should be applied during assembly; The special wrench should be used when the threaded coupling is tightened, and the torque should meet the standard requirements; After the piston and piston rod are assembled, it is necessary to measure whether the coaxiality and straightness on the full length are out of whack. After assembly, there should be no blocking sensation and uneven resistance when the piston assembly moves.

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.

In the hydraulic system, sometimes the inner layer of the rubber hose is peeled off, so that the oil circuit is on and off, resulting in irregular steel mill cylinder action. Troubleshooting method: Replace the rubber hose.

Answers to some questions about steel mill cylinder:

How to store hydraulic cylinder?
After cleaning the hydraulic cylinder with diesel or kerosene, apply lubricating oil and wrap it in oil paper, preferably in a wooden box, and store it in a dry and non-corrosive environment. The outer surface and inner surface of the hydraulic cylinder are sprayed with diesel oil, and the inner layer is covered with cloth and the outer coating of anti-rust oil is good. Put it in a dry place, clean it with diesel oil, and then apply a layer of anti-rust inside and outside the butter.

How to distinguish the size of hydraulic cylinder cavity?
The hydraulic cylinder has a rod cavity and a rodless cavity. The rod cavity is the cavity that the piston rod extends out. The rod cavity is of course small due to the existence of the piston rod. That's just relative.
