self-locking hydraulic cylinder are widely used in India，because of excellent fatigue and impact resistance，no need for deceleration device，long service life.So our company has designed self-locking hydraulic cylinder for customers from India.

Introduction to self-locking hydraulic cylinder:

When the self-locking hydraulic cylinder is customized, if there are high requirements for the quality of the self-locking hydraulic 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 self-locking hydraulic 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 self-locking hydraulic cylinder and avoiding the burn caused by grinding. After rolling, the reduction of surface roughness value can improve the matching property.

There are some honeycomb holes in the inner wall of the self-locking hydraulic cylinder, piston or piston rod surface. How is this formed? When we repair the self-locking hydraulic cylinder, we can see that there are some honeycomb holes on the inner wall of the self-locking hydraulic cylinder, the piston or the piston rod surface, which are caused by cavitation. Therefore, the cavitation of the self-locking hydraulic cylinder is targeted to prevent. Is very necessary.

Analysis of commonly used seals: The wear ring and slip ring commonly used on the self-locking hydraulic 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 coordination of the sliding parts of the self-locking hydraulic 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.

Answers to some questions about self-locking hydraulic cylinder:

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.

How many kinds of cylinder seal repair kit are there?
Very much, a wide variety of imported and domestic, J type, UHS, DHS, O-ring, Sterseal, etc., as well as support bars, materials are different, according to the size of the pressure selection is different, the appearance of the structure is different, the size is a variety, maintenance is generally selected according to the needs of the cylinder.
