Disassembling Process and Technology of Axial Piston Pump for Remanufacturing

Abstract

In response to the "circular economy" policy of the green environmental protection industry, the remanufacturing of axial piston pumps has been studied in depth. Firstly, the structure and working principle of each component of the axial piston pump are deeply studied, and then each component of the piston pump is regarded as an independent part, the contact and spatial relationship between the components are analysed. The disassembling specifications of remanufacturing must be strictly observed, and the principles of stability, safety and independence must be adhered to. Secondly, the spatial position of each component and the constraint relationship between adjacent components are studied in turn. The constraint matrix is established from the two aspects of space and contact, and the model of the disassembling device is designed according to the principle of priority and stability in the disassembling process. Then a complete disassembling process and the system are built, and the internal cycle procedure of the disassembling device is designed. Finally, through the simulation experiment and analysis of the virtual model of the disassembling device, the feasibility of the design scheme is verified by taking the former pump as an example. The results show that the disassembling effect of the disassembling device is all qualified and all parts are not damaged. It meets the requirements of stability, safety and independence, and the disassembly of various models and parts, which has the advantage of batch operation and can improve the disassembling efficiency and quality. It is ensured that the produced products meet the standard quality and can reduce the manufacturing cost and time, and save natural resources. Therefore, the disassembling device of the axial piston pump will be of great significance.
