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

Introduction to steel mill cylinder:

Analysis of commonly used seals: The wear ring and slip ring commonly used on the steel mill cylinder are generally made of polytetrafluoroethylene + graphite, because pure polytetrafluoroethylene is easy to produce plastic creep, which is only suitable for low pressure and low wear resistance conditions. If the sealing ring used is a composite material formed after adding graphite filler, the performance can be effectively improved, the ability to resist plastic creep is increased by 2 to 3 times, the initial deformation caused by the load is reduced by 30 to 60% : the rigidity is increased by 2 to 3 times: the dimensional stability under heat is increased by 2 times, and the hardness is increased by l0 to 15%.

In the process of using the steel mill cylinder, sometimes such a problem will occur, the steel mill cylinder can not act immediately after the instruction of the steel mill cylinder action is issued, and it must be moved after a short time, or sometimes it can move and stop moving, showing that the operation is very irregular. The cause and elimination of this failure mainly include air in the oil steel mill cylinder. Elimination method: exhaust through the exhaust valve. Check the piston rod reciprocating parts of the sealing ring for air inhalation, if so, replace the sealing ring.

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.

The commonly used buffer structure of the steel mill cylinder is composed of a piston boss and a steel mill cylinder head groove. When the piston moves close to the steel mill cylinder head, it gradually enters the groove, and the oil in the groove is extruded through the gap between the boss and the groove, which increases the oil return resistance, produces the braking effect and realizes the buffer. Generally, a buffer mechanism should be used when the pressure is above 10MP.

Answers to some questions about steel mill cylinder:

How to use a solenoid valve to control the expansion of a cylinder? Doesn't the solenoid valve only control on/off?
Use the solenoid valve P into A-B (generally equipped with oil circuit board) to connect the oil inlet interface at both ends of the cylinder, and the solenoid valve can be realized by power off (refer to the solenoid valve 2B2L, different solenoid valve actions are different).

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.
