servo hydraulic cylinder are widely used in Slovakia，because of long service life，smooth movement，high work efficiency.So our company has designed servo hydraulic cylinder for customers from Slovakia.

Introduction to servo hydraulic cylinder:

If the piston rod and servo hydraulic cylinder are stuck or the servo hydraulic cylinder is blocked, at this time, no matter how to operate, the servo 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 servo hydraulic cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.

When the servo hydraulic cylinder thrust is insufficient, check the hydraulic circuit for leaks. Including leakage of valves and hydraulic lines. The inspection method is to check and eliminate the leakage of the hydraulic connection line by manipulating the reversing valve. Also consider the relief valve. If the relief valve enters the dirt and jams the spool, so that the relief valve is normally open, the hydraulic oil will flow directly back to the tank through the relief valve bypass, resulting in no oil in the servo hydraulic cylinder. If the load is too large, although the regulating pressure of the relief valve has reached the maximum rating, the servo hydraulic cylinder still cannot get the thrust required for continuous action without action. If the regulating pressure is low, the pressure is insufficient to achieve the required vertebra force, which is manifested as insufficient thrust. Check and adjust the relief valve at this time.

The definition of the minimum starting pressure of the servo hydraulic cylinder refers to the minimum working pressure of the servo hydraulic cylinder in the no-load state, which is a comprehensive index reflecting the manufacturing and assembly accuracy of the servo hydraulic cylinder parts and the size of the sealing friction.

servo hydraulic cylinder diameter, rod diameter, stroke determination: Choose national standards or other standards servo hydraulic cylinder, avoid the selection of non-standard size, otherwise the difficulty of processing and manufacturing costs will be increased. The length of the servo hydraulic cylinder guide is determined by the length of the stroke. Check the strength of servo hydraulic cylinder, piston rod, screw, etc. according to the working pressure or load. At the same time, working pressure, ambient temperature, working medium and running speed are also the key to selecting seals.

Answers to some questions about servo hydraulic cylinder:

What's the use of three oil pipes on the cylinder?
The cylinder usually has an upper and lower oil chamber, one is connected to the upper oil chamber, one is connected to the lower oil chamber, sometimes a hydraulic lock will be added, that is, a hydraulic control check valve to prevent accidents when the oil pipe breaks, so the third pipe should be the control oil pipe of the hydraulic control check valve.

How to disassemble injection molding machine injection cylinder?
If it is not repaired for a long time, it is recommended to open both ends, comprehensively check the oil seal and piston ring inside, this is not much difficulty, pay attention to not install reverse when changing the oil seal, some piston rings are steel rings are rubber rings, and several interfaces of steel rings are not in the same position; Rubber ring pay attention not to install reverse; Be careful not to damage the oil seal when installing, otherwise it will soon leak oil.
