High speed, high efficiency, low energy consumption. Improve the working efficiency of hydraulic presses and reduce production costs. (2) Mechatronics and hydraulics integration. Make full and reasonable use of advanced mechanical and electronic technologies to promote the improvement of the entire hydraulic system. (3) Automation and intelligence. The rapid development of microelectronics technology provides sufficient conditions for the automation and intelligence of hydraulic presses. Automation is not only embodied in processing, it should be able to realize automatic diagnosis and adjustment of the system, and have the function of fault pretreatment. (4) The hydraulic components are integrated and standardized. The integrated hydraulic system reduces pipeline connections, effectively preventing leakage and pollution. Standardized components bring convenience for machine maintenance.
