解释不通,谁来帮帮我? to generate hydraulic pressure without running the system, you will need to bypass the air solenoid valves within the hydraulic panel by supplying 5-6 bar (~80 psi) drive air directly to the hydraulic pumps and air-piloted hydraulic relief valves (both circuits). apply 138 bar (2,000 psi) hydraulic pressure to both rolls / cylinders simultaneously and hold for 30 seconds. 想要不运行系统产生液压压力的话,你需要通过直接给液压泵和气控液压泄放阀(两个回路)提供5-6bar(大约80psi)的驱动气,来旁路掉液压控制板内的气动电磁阀。给两套辊/缸同时供138bar(2000psi)液压,保持30秒查看更多
