Basic introduction of electro-hydraulic push rod hydraulic cylinder

Electro hydraulic push rod hydraulic cylinder: The cylinder should be used correctly and maintained regularly. Before using the oil cylinder, it is necessary to deflate it, adjust the buffer regulating valve to a reasonable position, regularly check the cleanliness of the oil, clean the dust on the oil cylinder regularly, and pay attention to waterproofing and fire prevention. The interaction between the piston rod and the guide sleeve of the oil cylinder is crucial: the relative motion between the piston rod and the guide sleeve is the main factor causing external leakage. If the chrome plating layer on the surface of the piston rod peels off or produces longitudinal pull marks due to wear, it will directly lead to the failure of the seal. If the oil cylinder slips or crawls, please check whether there is any sticking inside the hydraulic cylinder, because improper assembly, deformation, wear or out of tolerance of the internal parts of the hydraulic cylinder, excessive movement resistance, cause the piston speed of the hydraulic cylinder to change with different stroke positions, resulting in slip or crawling. Most of the reasons are due to poor assembly quality of the parts, surface scratches or iron filings generated by sintering, which increase resistance and decrease speed. For example, the piston and piston rod are not concentric or the piston rod is bent, the hydraulic cylinder or piston rod is offset from the guide rail installation position, and the sealing ring is installed too tightly or too loosely. The solution is to repair or adjust again, replace damaged parts, and remove iron filings. The hydraulic cylinder requires a system filtration accuracy of not less than 80um, strict control of oil contamination, maintenance of oil cleanliness, regular inspection of oil performance, and necessary fine filtration and replacement of new working oil. Analysis of commonly used seals for oil cylinders: The materials of wear-resistant rings and slip rings commonly used on oil cylinders are generally polytetrafluoroethylene+graphite. Pure polytetrafluoroethylene is prone to plastic creep and is only suitable for low-pressure and low wear resistant working conditions. If the sealing ring used is a composite material formed by adding graphite filler, its performance can be effectively improved, the ability to resist plastic creep can be increased by 2-3 times, the initial deformation caused by load can be reduced by 30-60%, the rigidity can be increased by 2-3 times, the thermal dimensional stability can be increased by 2 times, and the hardness can be increased by 10-15%.

• 如何计算液压缸的速度
  If there is a throttle valve, the speed of the hydraulic cylinder will be adjustable. When the throttle is fully opened, the speed of the hydraulic cylinder reaches its maximum: maximum speed=oil pump displacement ÷ hydraulic cylinder chamber cross-sectional area. The displacement of the oil pump is a major indicator, which can be found on the nameplate, and some can also be known by the oil pump model; The cross-sectional area of the hydraulic cylinder chamber can be easily calculated. Just pay attention to the consistency of the measurement units. Due to the different cross-sectional areas of the rod chamber and rodless chamber of the hydraulic cylinder, the speed of advance and retreat may also be different.
• Which is more labor-saving, vertical lifting or angle lifting of hydraulic cylinder? Detailed answers and formulas!!!!! Thank you, hero
  This is related to the force arm. If 2 tons of force are most used at the point in your diagram, it must be the first one that requires effort. The thrust calculation method is also simple. In the above figure, the thrust is 2 tons x sin 16 ° x 9.8 N/kg, and then divided by the diameter of the hydraulic cylinder to obtain the pressure. This is the initial pressure, and the angle keeps changing as it is lifted. The thrust is also changing. It seems that the force of 2 tons in the above picture should act at the midpoint of 230, so there's no need to describe it simply in the following picture
• 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.
