According to the characteristics and requirements of dehydration in fabric industry,the hydraulic system of the dehydration press was designed.The pressure-boosting and pressure-keeping circuit based on accumulator and booster cylinder was adopted to increase the working pressure of the hydraulic cylinder.When the working pressure of the hydraulic cylinder was high and the flow rate was low,the unloading of the hydraulic system reduced the calorific value of the system.Pressure transmitter and proportional relief valve could monitor and regulate system pressure in real time.The control system of dehydration press was designed with Siemens S7-200 SMART PLC as the control core.The hydraulic system was simulated by AMESim.The system was simplified to reduce the complexity of the hydraulic system model.The pressure characteristic curve of the system was obtained by setting the parameters of the components and running them.The results show that the hydraulic system meets the design requirements of the dehydration press.
