Research About Remanufacture Technology Of Cylinder

Cylinder is one of important drive components in the construction machinery industry, and hydraulic cylinders are the last link of the power that is converted into mechanical actions. Hydraulic cylinders are used in many industries, of course, the damages to the cylinder and the effectiveness of the form and extent of damage vary with different cylinder. Every year, a large number of the cylinders are damaged or abandoned due to various reasons. If the damaged cylinders can be reused to recycle, it will achieve cost savings to the construction machinery industry in different degrees. The article focuses on the theoretical analysis and the development of technical standards and analyzes the damage forms of the cylinder, the cause of the malfunctions of the cylinder, remanufacturing technology and cylinder remanufacturing and so on.This paper first analyzes the structure and working principle of the cylinder, carry out the preliminary analysis about the damaged parts, and failure mechanism. Based on the statistics about the damages of cylinder, analyze the reason of the damages or malfunctions. Carry out Remanufacturing in the enterprise sector construction machinery cylinder failure, various forms of damage, as the analysis database. According to the failure in the form and extent of the damage, the feasibility of the damaged parts determines whether the remanufacturing technology is used in cylinder. Based on various forms of damage, implement the analysis of the main structure of the cylinder and main technical parameters, as well as its working principle of the cylinder. In addition, introduce the testing methods and results analysis method; analyze the failure of the cylinder on the machine to analyze the reasons of its failure. Detailed analysis on main damaged form of the cylinder are, and specific analysis on a damaged form are carried out; Analyze the cylinder dismantling process as well as the specific dismantling process, criteria and cost evaluation model are proposed and a disassembly instance of cylinder are proposed, including tooling, gauges and other specific contents; a systematic evaluation of the overall performance of the cylinder are advanced, and used on the cylinder remanufacturing process. Especially, a evaluation criteria about remanufacturing technology of cylinder are proposed. Finally, this article provides a cylinder parts remanufacturing instance.
