Ireland road paving machine hydraulic cylinder

(Ireland road paving machine hydraulic cylinder,produced by Hebei Hengyu company)

road paving machine hydraulic cylinder are widely used in Ireland,because of powerful torque,clever hydraulic energy conversion,simple structure and reliable operation.So our company has designed road paving machine hydraulic cylinder for customers from Ireland.

Introduction to road paving machine hydraulic cylinder:

The material of the sliding part of the road paving machine hydraulic cylinder piston sintered casting piston will cause sintering phenomenon when subjected to large transverse load. In this case, the sliding part of the piston should be made of copper alloy or welded to such material.

How to determine the working pressure of the road paving machine hydraulic cylinder: The pressure depends on the load size (i.e., F) and the type of equipment. The limitations of assembly space, economic conditions and component availability of the actuator should also be considered. In the case of a certain load, it is necessary to increase the structural size of the actuator if the working pressure is low, for some equipment, the size may be limited, and it is not economical from the point of view of material consumption; On the contrary, if the pressure selection is too high, the material, sealing and manufacturing accuracy of the pump, road paving machine hydraulic cylinder, valve and other components are also required to be high, which will inevitably increase the cost of equipment. In general, for equipment with a fixed size that is not too limited, the pressure can be selected lower, and the walking machinery should be selected higher.

When the road paving machine hydraulic cylinder is repaired, its inner and outer diameter and roundness should be accurately measured. If the inner hole of the road paving machine hydraulic cylinder is badly worn, it can be repaired by grinding the mandrel or honing on the boring machine. If the piston is worn, it can be repaired by electroplating, and serious wear should be replaced.

When installing the road paving machine hydraulic cylinder, the axial ends of the road paving machine hydraulic cylinder cannot be fixed. Due to the effect of liquid pressure and thermal expansion in the road paving machine hydraulic cylinder, there is axial expansion. If the two ends of the road paving machine hydraulic cylinder are fixed, all parts of the road paving machine hydraulic cylinder will be deformed. When disassembling the road paving machine hydraulic cylinder, it is strictly forbidden to hammer the road paving machine hydraulic cylinder and the piston surface, such as the road paving machine hydraulic cylinder hole and the piston surface is damaged, do not allow sandpaper grinding, to use a fine oil stone carefully grinding. The clearance between the guide sleeve and the piston rod should meet the requirements.

Answers to some questions about road paving machine hydraulic cylinder:

Why can't the hydraulic cylinder be pulled back after pushing to the limit?
May be long-term use to the limit position, resulting in serious wear caused! The solution is to add the stroke switch or disassemble and add gaskets before and after the piston.

How to calculate the tonnage of the hydraulic press? Example: The input cylinder pressure is 5Mpa, the end area of the cylinder piston is 100mm, and how much is the thrust tonnage?
F=P*S=5*10^6*3.14*(1/20)^2=39250N.
