India hydraulic cylinder,rolling mill cylinder manufacturer,rolling mill cylinder

(India rolling mill cylinder,produced by Hengyu Hydraulic Cylinder Factory）

rolling mill cylinder are widely used in India，because of excellent fatigue and impact resistance，no need for deceleration device，long service life.So our company has designed rolling mill cylinder for customers from India.

Introduction to rolling mill cylinder:

The coordination of the sliding parts of the rolling mill cylinder itself should not be too tight, the sealing friction force should not be too large, and H8 / f8 coordination should be selected between the piston rod and the guide sleeve; Check whether the size of the sealing ring is processed strictly according to the standard; If the V-shaped sealing ring is used, the sealing friction should be adjusted to a moderate degree.

The viscosity of the working oil used in the rolling mill cylinder is 29~74mm2/S, and ISO VG46 anti-wear hydraulic oil is recommended. Working oil temperature within the range of -20~80. C. When the ambient temperature and service temperature are low, the oil with lower viscosity can be selected.

The definition of the minimum starting pressure of the rolling mill cylinder refers to the minimum working pressure of the rolling mill cylinder in the no-load state, which is a comprehensive index reflecting the manufacturing and assembly accuracy of the rolling mill cylinder parts and the size of the sealing friction.

The wear of the hard chromium plating layer of the rolling mill cylinder is mostly caused by the grinding of the friction iron powder of the piston, and the wear is faster when there is water in the middle. Corrosion caused by the contact potential difference of the metal only occurs in the part of the piston contact, and the corrosion occurs in a point pattern. As mentioned above, when there is moisture in the middle, it will promote the development of corrosion. Compared with castings, the contact potential difference of copper alloy is higher, so the corrosion degree of copper alloy is more serious.

Answers to some questions about rolling mill cylinder:

When does the cylinder rotate?
The piston rod inside the multistage plunger cylinder can be rotated, and it will rotate when it is subjected to tangential force.

What does cylinder hob125*100 mean?
HOB is a series of hydraulic cylinder products, the use of pressure 14MPA, tie rod structure. 125 refers to the diameter of the cylinder and 100 refers to the stroke. The unit is millimeters.
