(Slovenia vehicle hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd）

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

Introduction to vehicle hydraulic cylinder:

vehicle hydraulic cylinder body inspection: The inner surface of the vehicle hydraulic cylinder and the piston seal are the main factors causing the leakage in the vehicle hydraulic cylinder, if the vehicle hydraulic cylinder has a longitudinal tensile mark, even if the new piston seal is replaced, it can not effectively eliminate the fault, the inner surface of the vehicle hydraulic cylinder mainly checks whether the dimensional tolerance and shape and position tolerance meet the technical requirements, there is no longitudinal tensile mark, and measures the depth of the longitudinal tensile mark, in order to take the corresponding solution.

vehicle hydraulic cylinder can not drive the load troubleshooting: oil pressure is too low. vehicle hydraulic cylinder selection specifications are too small. Leakage in vehicle hydraulic cylinder or associated hydraulic system element.

When the vehicle hydraulic cylinder is customized, if there are high requirements for the quality of the vehicle 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 vehicle 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 vehicle 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 vehicle hydraulic cylinder, piston or piston rod surface. How is this formed? When we repair the vehicle hydraulic cylinder, we can see that there are some honeycomb holes on the inner wall of the vehicle hydraulic cylinder, the piston or the piston rod surface, which are caused by cavitation. Therefore, the cavitation of the vehicle hydraulic cylinder is targeted to prevent. Is very necessary.

Answers to some questions about vehicle hydraulic cylinder:

What is the reason for the hydraulic cylinder sticking out and not retracting?
There are two reasons: First, the problem with the seal, if there are two seals on the piston, the top seal is broken. Second, when the hydraulic pressure itself is designed, the rod cavity area is too small, so that the desired return force can not be achieved during the return trip. You can first check whether the coupling is damaged; Then see if the relief valve in the oil line block is blocked. If the use time is too long, it needs to be cleaned, the hydraulic oil is very dirty and can block oil block. Electromagnetic directional valves can also be checked, but the chance of problems is relatively small, unless there is a product problem.

How does the self-locking cylinder work?
Hydraulic cylinder self-locking is divided into oil self-locking and mechanical self-locking. The oil circuit itself is equipped with a valve to maintain pressure, so that the hydraulic oil of the cylinder does not return to the tank, and the oil chamber of the cylinder is filled with a certain pressure of oil. However, this pressure holding self-locking is not very safe and reliable, and the plunger will slowly return if there is a leak. Mechanical self-locking is to install a nut on the plunger of the cylinder, and when the cylinder rises to the required position, the nut on the cylinder plunger is rotated to the end, and the cylinder block is in contact, so that the plunger will be fixed to the required height. When it is necessary to relieve the pressure, screw the nut on again and let the plunger return to the position. This kind of cylinder has a special name, called self-locking hydraulic cylinder.
