Basic Introduction to Leg Cylinder

Leg oil cylinder: After the fixed length machining, there should be no residue left during the deburring operation at both ends of the oil cylinder pipeline. Furthermore, placing steel pipes near the site where welding pipeline operations are carried out is the cause of foreign objects mixing in during welding. Pipes placed near the welding operation site must have their openings sealed. It must also be noted that the pipe fitting materials should be fully prepared on a dust-free workbench. What are the characteristics of the piston rod of the oil cylinder: The piston rod is actually widely used in the market. When we understand it, we not only need to look at the specific material, but also need to look at its characteristics in actual use? If we could have a detailed understanding, we would feel more at ease when making specific choices, because the materials used for the oil cylinder piston rod itself are also specific, and quality issues must be considered first during production and manufacturing.

As for the specific characteristics, through understanding, we can find that the overall strength is high, and the overall surface smoothness will be better after processing. It is indeed widely used in the current market. When choosing the oil cylinder piston rod, we can see if these specific surface treatment works are done well. To ensure that hydraulic oil cannot be injected into the oil cylinder, it is necessary to check whether the oil pipe, oil circuit, especially the hose joint have been blocked. The relevant oil circuit from the cylinder to the pump should be checked in sequence and the blockage should be eliminated; Check whether the sealing between the cone valve and the valve seat of the overflow valve is good; Check if the solenoid valve spring is damaged or if the solenoid coil is burnt out; Is the oil circuit switching insensitive. The daily inspection of the oil cylinder includes checking whether there is any leakage at the connection between the hydraulic cylinder and the pipe joint. Check for leaks at the piston rod of the hydraulic cylinder. Check if there is any leakage at the connection of the hydraulic cylinder barrel. Whether the hydraulic cylinder works normally and smoothly when moving. Is there any internal leakage in the hydraulic cylinder. If the hydraulic cylinder experiences sliding or crawling (stop and go), please check if there is any sticking inside the hydraulic cylinder. Improper assembly, deformation, wear, or out of tolerance of the internal components of the hydraulic cylinder, coupled with excessive resistance to movement, can cause the piston speed of the hydraulic cylinder to change with different stroke positions, resulting in slippage 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. At the same time, check whether the lubrication is good or whether the machining of the oil cylinder aperture exceeds the tolerance. Because the piston and cylinder, guide rail and piston rod are all relative to each other

Introduction to Leg Cylinder Manufacturers

Our company specializes in designing leg cylinders and also sells rotary cylinders, large stroke hydraulic cylinders, garbage truck cylinders, calender cylinders, and large hydraulic cylinders. After years of honest operation, our company has established reliable cooperative relationships with customers such as rubber cloth factories, electrolysis factories, weak acid manufacturing factories, pigment and watercolor pigment factories, eyeglass factories, and fountain pen factories.

Reference price for leg cylinder

The sales price of leg oil cylinders is determined by factors such as frequency of use, thrust size, system pressure, and whether pressure maintenance is required. The cost varies depending on temperature requirements, with common brands of leg oil cylinders costing between 1500/yuan and 6500/yuan.

  What are the structural characteristics of plunger cylinders?
• (1) A plunger hydraulic cylinder is a single acting hydraulic cylinder that can only move in one direction by hydraulic pressure, and the return of the plunger depends on other external forces or the weight of the plunger; (2) The plunger is only supported by the cylinder liner and does not come into contact with it, making the cylinder liner easy to machine and suitable for making long stroke hydraulic cylinders; (3) The plunger is always under pressure during operation, so it must have sufficient stiffness; (4) The weight of the plunger is often large, and when placed horizontally, it is prone to sagging due to its own weight, causing wear on the seals and guide on one side. Therefore, its vertical use is more advantageous.
  What is a hydraulic cylinder with a rod chamber and what is a rodless chamber. More detailed, preferably illustrated. Thank you
• The rod chamber refers to the end where the piston rod extends, while the rodless chamber refers to the chamber without the piston rod; I simply drew a pictogram
  How to correctly repair the bending machine cylinder
• The aging or deformation of the sealing ring on the inner wall of the wall and jacket.
  Of course, the direct solution is to replace the sealing ring. Generally, most domestic bending machine manufacturers use seals
