1. The use of CNC electro-hydraulic servo valve to control the hydraulic cylinder can achieve linear and real-time control of the output, so as to improve the property of the hydraulic cylinder;
2, cylinder barrel has strength, can bear dynamic working pressure, long time work without deformation;
3. With stiffness, it will not bend under lateral piston force and mounting reaction force;
4. Less friction between inner surface and guide parts and seals, which can be used for a long time;
5, cylinder barrel and flange to be good welding, no crack.
6, to the correct installation of the hydraulic cylinder sealing device: the installation of the sealing ring should pay attention to the direction of its installation, to avoid leakage due to installation
