Release time:
2023-04-21
maintenance personnel purchased a complete set of seals according to the specifications marked on the drawings, disassembled the hydraulic cylinder in sequence, carefully checked whether the inner cavity, piston and piston rod of the hydraulic cylinder were worn, and the original seal was damaged, and polished accordingly. When installing the new seal, apply a little lithium grease to prevent displacement during installation. Apply a layer of hydraulic oil to the inner cavity of the cylinder body to improve the smoothness. The cylinder body mouth faces upward, lift the piston to the center of the cylinder body, and slowly put it in. During the putting process, pay attention to the close contact between the seal and the piston to prevent damage. After being in place, lift the end cover and gently penetrate the piston rod. At the same time, do lubrication measures to prevent damage to the seal and evenly press the fixing bolts of the end cover and cylinder body. Then use the hydraulic pump to test the pressure, inject hydraulic oil from the pressurizing hole, and when the pressure is increased to the approved pressure, no hydraulic oil flows out when the pressure relief hole is disassembled, which proves that the hydraulic cylinder is qualified for installation.
This time, the employees repair the hydraulic cylinder by themselves, which not only provides an opportunity for the employees to practice and further improve the operation skills, but also saves the production cost of more than 10000 yuan for the enterprise, which can be described as killing two birds with one stone.
