[CN 202110115408.3] main cylinder of hydraulic press
[CN 202110115408.3] Title of a Hydraulic Machine Main Cylinder: Application Number of a Hydraulic Machine Main Cylinder: CN 202110115408.3 Applicant: Zhang Yan Application Date: 2021-1-28 Patent Type: Invention Application The present invention belongs to the technical field of hydraulic machine cylinders, specifically a hydraulic machine main cylinder, including a cylinder barrel, a movement unit and a sealing unit; The movement unit includes a piston and a piston rod. A first chute is provided in the cylinder; the first sliding groove is sealed and slidably connected to the piston; so that the sealing performance of the sealing ring in the main cylinder of the hydraulic machine is enhanced, the oil leakage of the main cylinder of the hydraulic machine is prevented, and the use efficiency of the hydraulic machine is improved; the replacement efficiency is improved when the sealing unit is replaced, Reduce the damage to the sealing ring, increase the service life of the sealing ring, avoid the phenomenon of prosperous oil leakage in the main cylinder of the hydraulic machine, and improve the hydraulic machine; filter, improve the pressure-reducing effect of the hydraulic oil, thereby improving the sealing of the sealing ring to the main cylinder; clean the inner wall of the main cylinder of the hydraulic press, reduce the damage of the sealing ring, improve the service life of the sealing ring, and discharge the gas of the main cylinder of the hydraulic press. Improve the sensitivity of the hydraulic press.
