(Brazil road paving machine hydraulic cylinder,produced by Hengyu Group）

road paving machine hydraulic cylinder are widely used in Brazil，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed road paving machine hydraulic cylinder for customers from Brazil.

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.

Causes and countermeasures of oil road paving machine hydraulic cylinder leakage: Cast iron ring seal allows a certain degree of internal leakage. The impurities in the road paving machine hydraulic cylinder will lead to premature wear of the piston seal, replace the piston seal; If the road paving machine hydraulic cylinder is visibly scarred, the road paving machine hydraulic cylinder must be replaced. It can be pressurized at one end of the road paving machine hydraulic cylinder and opened at the other end of the oil port to observe whether there is obvious internal leakage at the end of the oil port. Most road paving machine hydraulic cylinder piston drift may not come from the road paving machine hydraulic cylinder, the above method to determine the road paving machine hydraulic cylinder without internal leakage is helpful to determine the problem of the hydraulic system related components.

road paving machine hydraulic cylinder daily maintenance, should focus on checking whether the piston rod surface roughness and shape and position tolerance meet the technical requirements, if the piston rod bending should be calibrated to meet the requirements or according to the physical mapping, manufactured by a professional manufacturer. If the piston rod surface coating wear, slip damage, local spalling can be adopted to remove the coating, re-chrome surface processing process.

If the piston rod and road paving machine hydraulic cylinder are stuck or the road paving machine hydraulic cylinder is blocked, at this time, no matter how to operate, the road paving machine hydraulic cylinder does not move or has little action. At this time, check whether the piston and piston rod seal is too tight, whether it enters the dirt and gum deposits: whether the shaft line of the piston rod and the road paving machine hydraulic cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.

Answers to some questions about road paving machine hydraulic cylinder:

The diameter of the cylinder is 180mm and the pressure is 14mpa. How many tons can the cylinder hold?
Calculate the area of the cylinder, 3.14*9*9=254.34 square centimeters, take the approximate number of engineering, 1 mpa pressure is about 10 kg per square centimeter, 14 mpa pressure is 140 kg per square centimeter, that is 254.34*140=35607.6 kilograms, it can be known that the cylinder can be about 35 tons in theory.

How big is the motor and oil pump for the 80 cylinder?
Pump motor selection is not only related to cylinder diameter but also speed system, it is recommended to provide system diagram and speed requirements, generally speaking, most of the 80 cylinder on the market is equipped with 3-4KW motor, 10-20 oil pump.
