(Latvia stern plate hydraulic cylinder,produced by Hebei Hengyu company）

stern plate hydraulic cylinder are widely used in Latvia，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed stern plate hydraulic cylinder for customers from Latvia.

Introduction to stern plate hydraulic cylinder:

Before the stern plate hydraulic cylinder is removed, the relief valve should be loosened to reduce the pressure of the hydraulic circuit to zero, and then the power supply should be cut off to stop the hydraulic device. After loosening the oil port piping, the oil plug should be applied to plug the oil port.

The repair method of stern plate hydraulic cylinder wear: 1. Metal repair material is applied to the scratched surface; The first layer should be thin, uniform and fully covered with the scratched surface to ensure the best adhesion between the material and the metal surface, and then apply the material to the entire repair site and press repeatedly to ensure that the material is filled and reaches the required thickness, so that it is slightly higher than the surface of the guide rail; 2, the material at 24℃ to fully achieve the performance of 24 hours, in order to save time, can be through the tungsten halogen lamp to increase the temperature, the temperature rises 11℃, the curing time will be reduced by half, the best curing temperature 70℃; 3. After the material is cured, use a fine grinding stone or a scraper to repair and smooth the material higher than the surface of the guide rail, and the construction is completed.

In recent years, the processing process of the stern plate hydraulic cylinder generally adopts the rolling method, which is a pressure finishing processing, which uses the cold plastic characteristics of the metal at room temperature, and uses the rolling tool to exert a certain pressure on the surface of the workpiece, so that the surface metal of the workpiece produces plastic flow, and fills in the low concave trough of the original residue, and the roughness value of the workpiece surface is reduced. Due to the plastic deformation of the rolled surface metal, the surface tissue is cold hardened and the grain is fine, forming a dense fiber, and forming a residual stress layer, and the hardness and strength are increased, thus improving the wear resistance, corrosion resistance and compatibility of the workpiece surface. Rolling is a plastic machining method without cutting.

When the piston speed of the stern plate hydraulic cylinder is high, the steel ball of the check valve flows with the oil flow, so that the valve hole is blocked, and the stern plate hydraulic cylinder moves irregularly. Elimination method: Replace the steel ball with a cone valve or spool with a guide shoulder.

Answers to some questions about stern plate hydraulic cylinder:

How to take out the diaphragm of hydraulic cylinder? The septum ring is also known as the septum sleeve, when the cylinder is too long, and does not need too much travel, add the septum sleeve, limit the stroke of the hydraulic cylinder, set on the piston rod, only contact with the guide sleeve and piston, do not cooperate with the cylinder, limit the stroke, take out the difficulty is different, need to have such a professional tool, before taking out to consult the manufacturer.

How to control the speed of the cylinder?
High demand control, it is necessary to use servo closed-loop control, you can adjust the speed at will. Reference: Hydrodynamic Motion Control Practical Design Guide.
