Introduction to electro-hydraulic servo hydraulic cylinder

Electro hydraulic servo hydraulic cylinder: Regularly inspect the chrome plating layer of the cylinder for damage: fully extend the cylinder and carefully check for surface damage such as bumps, strains, welding slag, etc. If the surface damage is located less than 20cm from the cylinder body and the depth of damage is less than 5mm, it should be repaired in a timely manner to prevent long-term damage to the cylinder seal. It is strictly prohibited to have welding slag on the surface of the oil cylinder. Hydraulic cylinder misoperation or malfunction may be caused by the following reasons, which can be investigated from these aspects: (1) stuck 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. (2) The piston rod is stuck with the cylinder or the hydraulic cylinder is blocked. At this point, no matter how you manipulate it, the hydraulic cylinder will not move or move very little. At this point, it is necessary to check whether the piston and piston rod seals are too tight, whether dirt and gum deposits have entered, whether the axis of the piston rod and cylinder is aligned, whether vulnerable parts and seals have failed, and whether the load carried is too high. When repairing a hydraulic cylinder, it is necessary to accurately measure its inner and outer diameters as well as its roundness. If the inner hole of the cylinder is severely worn, it can be repaired by grinding the core shaft or honing on a boring machine; If the outer circle of the piston is worn, it can be repaired by electroplating, and if it is severely worn, it should be replaced. When the hydraulic cylinder needs to be stored for a period of time, please follow the recommended method as follows: the hydraulic cylinder should be stored in a dry, clean, and non corrosive indoor environment, and attention should be paid to protecting the hydraulic cylinder from internal corrosion and external damage. If indoor requirements cannot be met, the oil cylinder should be placed on a hardened and well drained ground with a cushion of at least 30cm, and the upper part should be covered with waterproof storage. It is forbidden for the oil cylinder to come into direct contact with water vapor for a long time. The hydraulic cylinder should be placed as vertically as possible, with the piston rod facing upwards, which can minimize corrosion caused by condensation that may occur inside the hydraulic cylinder, as well as permanent deformation of the seals caused by the weight of the piston and piston rod. When storing the shield in the shield machine, place the support shoes facing upwards. Keep the oil port protective cover until the pipeline is connected. When stored for a long time, the piston on both sides of the hydraulic cylinder should be filled with the oil cylinder model marked by the manufacturer: for example, 160/100-1150, its meaning: from a professional perspective, 160 refers to the cylinder diameter of the hydraulic cylinder, which is 160mm, followed by 100, which refers to the rod diameter, which is 100mm. And 1150 refers to the cylinder stroke, which is 1150mm. Therefore, everyone should have a correct understanding on this point and not make mistakes.

Maintenance and related issues of electro-hydraulic servo hydraulic cylinder

• What adhesive should be used if there are cracks in the oil cylinder
  There is a type of cast iron adhesive that can be purchased in the industrial market. Formula A and B, which means one tube is A and the other tube is B, are prepared in proportion when used. Please refer to the instruction manual. After the glue dries, polish it and then grind it again.
• What are the four types of hydraulic cylinders for car cranes
  The four types of hydraulic cylinders for automobile cranes generally refer to the telescopic hydraulic cylinder for the boom (adjusting the length of the boom), the amplitude hydraulic cylinder for the boom (adjusting the elevation angle of the boom), the horizontal telescopic hydraulic cylinder for the legs, and the vertical hydraulic cylinder for the legs.
• Excavator oil cylinder, what's the problem with oil leakage
  In general, hydraulic cylinder leakage is divided into two types: internal leakage and external leakage. As long as we observe carefully, we can determine the cause of external leaks. However, it is difficult to determine the cause of internal leakage in hydraulic cylinders because we cannot directly observe the location of the internal leakage. So, let's briefly explain the reasons for internal and external leaks in hydraulic cylinders. 1、 The damage to the seal between the protruding end of the piston rod and the piston rod caused by external leakage is mostly due to the piston cylinder being roughened, as well as aging. The seal between the protruding end of the piston rod and the cylinder liner is damaged, which is mostly caused by long-term use and aging of the seal. There are also many cases where the seal is compressed and damaged by excessive force on the upper cover
• What is the difference between actual hydraulic cylinders in China?
  Mid air solid hydraulic cylinder, according to conventional understanding, refers to whether the piston rod is solid or hollow. Generally, ordinary hydraulic cylinders have solid piston rods.? ? ? ? ? ? ?? Hollow hydraulic cylinder refers to a hydraulic cylinder with a hollow piston rod structure, as shown in the attached figure. The function of a hollow piston rod: 1. The piston rod is hollow and can be threaded with a screw in the middle. ????? For example, the clamping hydraulic cylinder of a sawing machine, the center of the piston rod is threaded through the screw rod, and part of the stroke is manually operated while part of the stroke is automatically operated by hydraulic pressure. , 2， The hollow hole of the piston rod can be used to conduct oil circuits and achieve special oil circuits. 3. The hydraulic cylinder is relatively large, the piston rod is relatively large, and the stroke is long. In this case, the piston rod is made hollow to reduce activity
