ABSTRACT:The fuel tank popular as the containers for storage fuel, this design focus on research the hydraulic system design of the fuel tank molding machine. The fuel tank molding machine with hydraulic control system can be more high-speed, high efficiency, low energy consumption .Increase the efficiency of the hydraulic machines and reduce production costs .And realize hydraulic integration. Fully rational use of mechanical and electronic aspects of advanced technology for the entire hydraulic system is perfect. 

　　　In the design process, the first conducted a systematic analysis of the working conditions. Then according the working conditions to defined the hydraulic system schematic. In the analysis of the principle of the system, according to certain parameters, to calculate the flow rate of the system and determining the system pressure. According to the hydraulic design manual, there is a selection of hydraulic components. Then , computing the parameters of the hydraulic cylinder to determine the design of the hydraulic cylinder.  In order to make the hydraulic component integration, standardization, and the hydraulic system is compact, easy to install, assembly cycle is short, the design also conducted a manifold design. Achieve without pipe connection between components, elimination of tubing, pipe joints caused by leakage, vibration and noise. The whole system achieved configuration flexibility, neat appearance, easily maintenance.
