Select the cylinder type correctly according to the working requirements and conditions. It is required that there is no impact phenomenon and impact noise when the cylinder reaches the end of the stroke; Cushion cylinder shall be selected; Light weight is required; It is required to select light cylinder; Changzhou Hydraulic machinery Narrow installation space and short stroke are required; It is required to select thin cylinder; It is required to have transverse load, and the cylinder with guide rod can be selected; High braking accuracy is required, and locking cylinder can be selected; It is not allowed to rotate the piston rod, and the cylinder with rod non rotation function can be selected; Changzhou Hydraulic machinery Price In corrosive environment, corrosion-resistant steel cylinders shall be selected.

Items to be checked when the speed of hydraulic cylinder slows down. 1. Where and what type of oil cylinder has been used for several years, Changzhou Hydraulic machinery What is the working pressure. You don't have any of these. How can I troubleshoot them for you. Check the lower seal if there is internal leakage. 2. It is likely that the internal working pressure of the oil cylinder has decreased. 3. Check whether the system is blocked, Changzhou Hydraulic machinery Price In addition, check whether the oil cylinder seal ring is damaged, and then check whether the piston rod is damaged. Basically, these aspects can identify the problem.

How to install and fix the hydraulic cylinder? There are two common ways to fix the hydraulic cylinder: the first is the square hydraulic cylinder fixed on the B plate, and the hydraulic cylinder needs to be positioned on the B plate. The second is a round hydraulic cylinder fixed on the ejector plate. It should be noted that the thimble plate locking screw needs to be added next to the hydraulic cylinder, and the force at this position is large, Changzhou Hydraulic machinery Prevent tension deformation. Another point is to inscribe words on the hydraulic cylinder, and write down the stroke of the hydraulic cylinder for easy verification. To correctly install the sealing device at each position of the hydraulic cylinder: Changzhou Hydraulic machinery Price When installing the O-ring seal, pay attention to its installation direction to avoid oil leakage due to installation. Its lip should face the oil chamber with pressure.

The oil cylinder shall be assembled in a special workshop or assembly area, and the temperature shall be kept at 20~250C, Changzhou Hydraulic machinery Price It shall be far away from the tuyere, dust and cutting area, with fresh air, no dust and no noise; Avoid direct glare. The assembly room shall be equipped with installation platform, sufficient working position apparatus, assembly turnover vehicle Changzhou Hydraulic machinery Lifting and hoisting equipment and the following special basic equipment. a: Cylinder loader; b: Another cylinder cleaning machine is used to heat and clean another part; c: Pressure test equipment, used for pressure test of oil cylinder; d: The air duct is used to clean and dry the other parts after cleaning.
