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

Introduction to servo hydraulic cylinder:

The repair method of the servo hydraulic cylinder: the repair of the servo hydraulic cylinder must use brush plating. This is because this repair method can be carried out on site, and the repair effect is good. In this way, loading and transportation can be eliminated to shorten the repair time and improve work efficiency. In addition, the coating obtained by brush plating has good binding force and will not have obvious boundaries. Moreover, the repair surface has high hardness and good wear resistance.

The servo hydraulic cylinder should be avoided for a long time without use, if it is indeed idle for a long time for some reason, it should also be regularly turned on for empty operation, so that its parts can be fully lubricated, so as to avoid rust on the working surface and affect the normal work in the future. (If it cannot be turned on and run, a small amount of lubricating oil can be applied on its outer surface for protection) ' The use of the servo hydraulic cylinder should pay attention to: the operation should be as far away from the servo hydraulic cylinder as possible, to avoid falling objects, knocking, rubbing the servo hydraulic cylinder coating. When cleaning the servo hydraulic cylinder, only use soft materials (such as cotton) to wipe, and do not scratch high-hardness materials. Do not use the servo hydraulic cylinder when the oil temperature exceeds 70 ° C.

The pressure, temperature, medium and speed of different types of seals are not the same, water-ethylene glycol medium (HFC) can not be sealed with polyurethane, it can only use rubber seal; When the servo hydraulic cylinder is running fast, it must be sealed with slip ring, such as Sterseal, Glairing, GD1000K, TDI, etc., when the running speed is slow, Yx, U, V combination seals can be used; Fluorine rubber seal is used in high temperature and high pressure environment; When the running speed is fast, the buffer sleeve and buffer valve must be considered.

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

Answers to some questions about servo hydraulic cylinder:

What parameters do I need to provide when purchasing hydraulic cylinders?
The main technical parameters of the hydraulic cylinder: 1. Cylinder diameter; Cylinder diameter, inner diameter size; 2. Piston rod diameter; 3. Cylinder stroke; 4. Cylinder pressure; The working pressure of the cylinder is often calculated using the test pressure, which is less than 16MPa multiplied by 1.5 and higher than 16 multiplied by 1.255. Import and export diameter and thread parameters; 6. Whether there is buffer; According to the working conditions, the piston rod extension contraction is generally buffered if the impact is large. 7. Installation method of oil cylinder, etc.

How to calculate the cross-sectional area of hydraulic cylinder?
Hydraulic cylinder cross section integral rod cavity and rodless cavity: rod cavity is cylinder inner wall cross-sectional area - piston rod cross-sectional area; The rodless cavity is the cross-sectional area of the inner wall of the cylinder. If the working pressure p and the output force F are known, the effective cross-sectional area A=F/p can be calculated.
