Ethiopia 500 tons hydraulic press cylinder

(Ethiopia 500 tons hydraulic press cylinder,produced by Hengyu Hydraulic Cylinder Factory)

500 tons hydraulic press cylinder are widely used in Ethiopia,because of excellent fatigue and impact resistance,no need for deceleration device,long service life.So our company has designed 500 tons hydraulic press cylinder for customers from Ethiopia.

Introduction to 500 tons hydraulic press cylinder:

Analysis of commonly used seals: The wear ring and slip ring commonly used on the 500 tons hydraulic press 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%.

The definition of the minimum starting pressure of the 500 tons hydraulic press cylinder refers to the minimum working pressure of the 500 tons hydraulic press cylinder in the no-load state, which is a comprehensive index reflecting the manufacturing and assembly accuracy of the 500 tons hydraulic press cylinder parts and the size of the sealing friction.

The coordination of the sliding parts of the 500 tons hydraulic press 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.

After chrome plating of the piston rod of the 500 tons hydraulic press cylinder, the surface flatness is not fully treated: After chrome plating of the piston rod surface, the method of post-plating polishing should be changed to post-plating polishing. Although it is necessary to increase the thickness of the coating before grinding (generally increased by about 0.02 in the diameter direction), it can remove chrome plating defects well, and test the binding force of the coating. In addition, due to the micro-roughness of the grinding surface, the trough can store lubricating oil, which can improve the wear resistance and extend the service life.

Answers to some questions about 500 tons hydraulic press 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 calculate the tonnage of hydraulic cylinder? The tonnage of the cylinder refers to the output force of the cylinder under rated working pressure: 1, for single rod piston hydraulic cylinder, it can be calculated by the area of the circle corresponding to the inner diameter of the cylinder A (square centimeter), and the rated working pressure of the system p (mpa), the value is equal to 10pA kg force, and the ton is 0.01pA. 2, for the double rod piston hydraulic cylinder, with A(square centimeter) to indicate the cylinder cylinder diameter and piston rod outer diameter defined by the ring area, with p (mpa) to indicate the rated working pressure of the system, the output force of the cylinder is 0.01pA ton force.
