Egypt unidirectional cylinder

(Egypt unidirectional cylinder,produced by Hengyu Hydraulic Cylinder Factory)

unidirectional cylinder are widely used in Egypt,because of no need for deceleration device,long service life,smooth movement.So our company has designed unidirectional cylinder for customers from Egypt.

Introduction to unidirectional cylinder:

When the unidirectional cylinder is customized, if there are high requirements for the quality of the unidirectional cylinder, it is best to use rolling processing, because the surface layer has surface residual compressive stress, which helps to close the surface of the small crack, preventing the expansion of erosion. Thus, the corrosion resistance of the surface can be improved, and the fatigue crack can be delayed or expanded, and the fatigue strength of the unidirectional cylinder can be improved. By rolling forming, a cold working hardening layer is formed on the rolling surface, which reduces the elastic and plastic deformation of the contact surface of the grinding pair, thereby improving the wear resistance of the inner wall of the unidirectional cylinder and avoiding the burn caused by grinding. After rolling, the reduction of surface roughness value can improve the matching property.

Disassembly unidirectional cylinder: When disassembly unidirectional cylinder, strictly prevent damage to the screw thread at the top of the piston rod, the screw thread of the unidirectional cylinder head and the surface of the piston rod. It should also be noted that the piston cannot be played out from the unidirectional cylinder.

After chrome plating of the piston rod of the unidirectional 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.

The piston rod and guide sleeve function of the unidirectional 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.

Answers to some questions about unidirectional cylinder:

What is the material of the cylinder support ring?
Generally, it is polytetrafluoroethylene doped with copper powder, or polyformaldehyde, and copper sleeves, there are also nylon, resin and so on.

What are the problems that cause hydraulic cylinder shaking?
1, the oil supply is not smooth, the hydraulic oil filter is half blocked. 2. The oil level in the oil storage tank is lower than the minimum oil level. 3, there is air in the hydraulic system. 4, the supply oil pump is damaged or not working properly. 5, the hydraulic oil is not replaced for a long time.
