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

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

Introduction to road paving machine hydraulic cylinder:

The piston rod and guide sleeve function of the road paving machine hydraulic cylinder is crucial: the relative motion pair between the piston rod and the guide sleeve is the main factor causing external leakage, if the chrome layer on the surface of the piston rod is spalling or producing longitudinal tensile marks due to wear, it will directly lead to the failure of the seal.

road paving machine hydraulic cylinder seal leakage causes and countermeasures: a. Loose tie rod nut will cause leakage, tighten the tie rod nut according to the torque requirements of tie rod nut, test no leakage can continue to use. b. Pressure exceeding the limit will also cause leakage. Replace the road paving machine hydraulic cylinder seal and re-tighten the tie rod nut to reduce the pressure to the nominal pressure range of the road paving machine hydraulic cylinder. c. The road paving machine hydraulic cylinder seal is extruded, if the O-ring is obviously extruded at the road paving machine hydraulic cylinder seal, replace the road paving machine hydraulic cylinder seal.

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.

Do not regularly check the damage of the chrome layer of the road paving machine hydraulic cylinder: completely extend the road paving machine hydraulic cylinder and carefully check whether there is any surface damage such as injury, strain, welding slag, such as the surface damage position, in the road paving machine hydraulic cylinder block < 20cm, and the damage depth < 5mm, should be repaired in time to prevent long-term damage to the road paving machine hydraulic cylinder seal. Welding slag is strictly prohibited on the surface of the road paving machine hydraulic cylinder.

Answers to some questions about road paving machine hydraulic cylinder:

What is st represented in the cylinder formula?
St is the original unit of kinematic viscosity, the abbreviation of Stokes, that is, Stokes, short for S. cm2/s has now been used. 1 s (St) = 10^-4m2/s.

What is the difference between single acting hydraulic cylinder and double acting hydraulic cylinder?
Single action hydraulic cylinder is a single direction force work, the return of the plunger depends on itself or the weight of the mechanism to return. The double acting hydraulic cylinder is mainly different from the extension and retraction of the piston (the thrust and tension of the saying), which are all operated by the action of liquid pressure.
