Cote d 'Ivoire hydraulic cylinder,rolling mill cylinder manufacturer,rolling mill cylinder

(Cote d 'Ivoire rolling mill cylinder,produced by Hebei Hengyu company）

rolling mill cylinder are widely used in Cote d 'Ivoire，because of powerful torque，clever hydraulic energy conversion，simple structure and reliable operation.So our company has designed rolling mill cylinder for customers from Cote d 'Ivoire.

Introduction to rolling mill cylinder:

Do not regularly check the damage of the chrome layer of the rolling mill cylinder: completely extend the rolling mill cylinder and carefully check whether there is any surface damage such as injury, strain, welding slag, such as the surface damage position, in the rolling mill cylinder block < 20cm, and the damage depth < 5mm, should be repaired in time to prevent long-term damage to the rolling mill cylinder seal. Welding slag is strictly prohibited on the surface of the rolling mill cylinder.

rolling mill cylinder abnormal sound, hysteresis phenomenon cause and elimination method: the piston rod is extended with abnormal sound and hysteresis, if the rolling mill cylinder is placed for a period of time, the rolling mill cylinder may enter the air, and the movement can be normal after dozens of repeated movements. If it still cannot be eliminated, check whether the load is aligned with the axis of the piston rod; Retracted piston rod installation helps to align the load with the piston rod. If the flow is unstable, it will also lead to abnormal movement of the piston rod. Check the relevant components of the hydraulic system.

The rolling mill cylinder can not be used as grounding electrode to avoid electric damage to the piston rod.

Because of the slightly complex structure of the buffer rolling mill cylinder, sometimes there will be problems, such as when the rolling mill cylinder with the buffer device is started in reverse, the piston often stops temporarily or reverses. Elimination method: The orifice of the check valve is too small, so that the amount of oil entering the buffer chamber is too small, and even a vacuum occurs, so the above fault phenomenon will occur when the buffer plunger leaves the end cover. In this regard, the orifice of the check valve should be increased.

Answers to some questions about rolling mill cylinder:

The hydraulic cylinder is slow when moving forward and faster when moving back.
If the cylinder is single, it is slow when it is moving forward without the rod cavity, and fast when it is shrinking.

Can pneumatic cylinder be used as hydraulic cylinder?
The pneumatic cylinder can only be used for pressure below 1MPA, and if it is used for hydraulic, the pressure should be under 1MPA, which may not meet the strength requirements. And the seals should use fluorine rubber to avoid corrosion. But pneumatic cylinder used as hydraulic cylinder is not whimsical, in fact, there is such a use. The pneumatic system has a natural defect, that is, the speed is unstable, especially in the case of low speed. The hydraulic pressure is very stable, if you do not want to buy a set of hydraulic system, while the strength of the cylinder is not large, you can use compressed air to push the hydraulic oil, with hydraulic oil to drive the cylinder, The force is the same as compressed air, but very smooth.
