How can the cylinder piston rod be improved

At present, according to the characteristics of the rolling bearing of the oil cylinder and the hydraulic transmission system, the working characteristics of the oil cylinder have been mastered, and the main parameters that are harmful to the working characteristics have been found out. The specific gravity of the working characteristics is obtained, the stability of the equipment is improved, the vibration characteristics of each module in the work are grasped as soon as possible, and the inner cavity support force of the oil cylinder of the construction machinery and mining equipment is analyzed.

In the above-mentioned traditional structure of cylinder piston rod fracture, the new piston rod drum structure has obtained and developed a detailed basic theoretical analysis and design scheme, which provides a basic theoretical basis for the production, processing and specific application of the drum piston rod. Taking the hydraulic transmission system of the excavator working device as an example, the mathematical analysis model and model simulation of the state variables are established. When analyzing the regularity of the working pressure when the pen holder stretches, the position of the working pressure, shock and working pressure chamber in the working pressure rebound period is proposed, and the steady-state analysis expression of the battery charging working pressure is given. The highest value of the working pressure shock far exceeds the steady-state value of the working pressure rebound.

According to the working standard of the excavator, select the oil cylinder seal for excavator analysis, and confirm the sealing performance of the selected structure according to the inspection and installation. In this paper, the variable part of the strain force cylinder with a large critical value is obtained by the kinetic energy calculation method and part of the main parameter variability. The three-dimensional mathematical analysis model of the luffing oil cylinder is established by using the finite element analysis software, and the relative solution of the main parameters is given.

Based on the comparison of the basic theoretical value and the analysis results, a calculation method that can be applied to the actual activities of the engineering project is obtained, which is of great practical significance as a manual for the reliability design scheme and certification of the oil cylinder in the future. It can realize the horizontal pin and the single oil cylinder, which ensures the safety of the single oil cylinder of the crane telescopic technology, and is reliably locked on the telescopic system, avoiding accidents and reducing the hydraulic pressure and circuit system. Reliability regulations apply to lifting equipment and other manufacturing industries.
