Basic Introduction to Servo Hydraulic Cylinder

Servo hydraulic cylinder: The commonly used buffering structure of the oil cylinder is composed of a piston boss and a cylinder head groove. When the piston moves closer to the cylinder head, it gradually enters the groove and squeezes out the oil in the groove through the gap between the boss and the groove, increasing the return oil resistance and producing a braking effect to achieve buffering. Generally, buffer mechanisms should be selected when the pressure is above 10MP. How to solve the problem of stuck oil cylinder valve core or blocked valve hole: When the flow valve or directional valve core is stuck or the valve hole is blocked, the hydraulic cylinder is prone to misoperation or malfunction. At this time, the contamination of the oil should be checked; Check if dirt or gum deposits are stuck in the valve core or blocking the valve hole; Check the wear of the valve body, clean and replace the system filter, clean the oil tank, and replace the hydraulic medium. The pressure, temperature, medium, and speed borne by different types of seals in oil cylinders are different. Water ethylene glycol (HFC) medium cannot be sealed with polyurethane, only rubber seal can be used; When the operating speed of the oil cylinder is fast, slip ring seals such as special seals, gaskets, GD1000K, TDI, etc. must be used. When the operating speed is slow, Yx type, U-shaped, V-shaped combination seals, etc. can be used; Sealing with fluororubber in high temperature and high pressure environments; When running at high speeds, it is necessary to consider using buffer sleeves and buffer valves. How to repair the damaged oil cylinder: When there is slight deformation and shallow pulling marks on the cylinder, strong honing technology is used to repair the cylinder. The strong honing process can repair cylinder barrels that are within 2.5 times the original tolerance. It uses a powerful honing machine to hone the parts where the size or shape error exceeds the tolerance, so that the overall size, shape tolerance, and roughness of the cylinder meet the technical requirements. Excessive pressure on the sliding surface of the oil cylinder piston can cause sintering phenomenon. The piston tilts due to the self weight of the piston rod, resulting in friction, or the pressure on the sliding surface of the piston increases due to lateral loads, which can cause sintering phenomenon. When designing a hydraulic cylinder, it is necessary to study its working conditions and pay full attention to the length and clearance dimensions of the piston and liner.

Reference price for servo hydraulic cylinder

The price of servo hydraulic cylinders is determined by factors such as operating speed, synchronization requirements, usage environment, technical requirements, etc. The factory price also varies depending on the stroke range. The cost of common brands of servo hydraulic cylinders ranges from 800/yuan to 8000/yuan.

Maintenance and related issues of servo hydraulic cylinder

• How to determine the rated working pressure of a hydraulic cylinder
  Under normal circumstances, the working pressure should be determined based on the size of the load and the installation space (the allowable diameter of the oil cylinder). In some special occasions, it is required that the smaller the oil cylinder, the better, and the pressure level must be increased. The cylinder pressure is related to the expected cost. The higher the pressure, the thicker the wall thickness, and the higher the cost, but conversely, when the pressure is low (at the same thrust), a larger cylinder diameter is required, and the cost is equally high. So the rated pressure of the oil cylinder is concentrated around 35 megapascals, taking into account both the cylinder diameter and wall thickness.
• What is hydraulic cylinder guide rail?
  The hydraulic cylinder itself should not move, it is the piston that moves. The guide rail you mentioned should be used to guide the mechanism connected to the protruding end of the piston. For example, in commonly used hydraulic presses, the guide column on top is used to guide the pressure plate connected to the piston.
• What series is the integration of oil cylinder, motor, and oil pump
  The motor and oil pump are integrated into the oil pump motor group, and together with the oil cylinder, it is a hydraulic system. Where are you planning to use it
• What valve is used to control the speed of the hydraulic cylinder when lifting it
  Hydraulic cylinders are generally installed with the piston facing downwards for lifting. To achieve fast or slow replacement of the hydraulic cylinder, you can add a two position three-way electromagnetic directional valve and a throttle valve to the bottom oil port of the hydraulic cylinder in one branch to achieve speed replacement. The control method can be time control or stroke switch control. If you want to achieve more precise control, you can use proportional valve control.
