(Oman rolling mill cylinder,produced by Hengyu Group）

rolling mill cylinder are widely used in Oman，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed rolling mill cylinder for customers from Oman.

Introduction to rolling mill cylinder:

How to repair the rolling mill cylinder body when it is damaged: When the rolling mill cylinder has trace deformation and shallow tensile marks, the rolling mill cylinder is repaired by strong honing process. The heavy honing process can repair rolling mill cylinders up to 2.5 times out of tolerance than the original tolerance. It honed the parts with excessive size or shape error through a powerful honing machine, so that the overall size, shape tolerance and roughness of the rolling mill cylinder can meet the technical requirements.

When the rolling mill cylinder needs to be disassembled for maintenance due to leakage and other faults, the piston should be moved to the bottom position of the rolling mill cylinder, and hard beating and sudden drop are strictly prohibited during disassembly.

The internal leakage of the rolling mill cylinder should be prevented when the rolling mill cylinder is used. The internal leakage of rolling mill cylinder includes the leakage caused by excessive wear of rolling mill cylinder block seal, piston rod and seal cover seal and piston seal. The cause of sealing leakage between the piston rod and the seal cover is that the seal is wrinkled, squeezed, torn, worn, aging, deterioration, deformation, etc., and a new seal should be replaced at this time.

When the oil pressure of the rolling mill cylinder inlet is too low to reach the specified value, the leakage situation of the relevant oil system should be checked and the leakage should be eliminated; Check the piston and piston rod seal ring for damage, aging, loose and other phenomena; Check whether the hydraulic pump and pressure valve are faulty.

Answers to some questions about rolling mill cylinder:

Hydraulic cylinder performance requirements?
Hydraulic cylinder performance requirements: hydraulic cylinder is the hydraulic system to achieve energy transfer, conversion and control of the working medium, in addition, it is also responsible for the lubrication of the system, rust prevention, corrosion prevention and cooling. The performance of hydraulic oil will make the system flexible, accurate and reliable. Hydraulic performance requirements are determined according to the design parameters of the hydraulic system, operating conditions, the structure of the hydraulic pump and the working environment. Appropriate viscosity and good viscosion-temperature performance Viscosity is an important performance indicator of hydraulic pressure, which has an important impact on the smooth operation of the hydraulic system and the friction parts. The low temperature performance of hydraulic oil includes three aspects: low temperature flow, low temperature start-up and low temperature pumping.

Hydraulic cylinder load algorithm?
If it is thrust, load = working pressure x piston area. If it is pulling force, load = working pressure x(piston area - piston rod area).
