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.为了在不启动系统的情况下形成液压力,需要绕过液压控制面板内的空气调节阀,给液压泵和空气液力释放阀这两个回路都提供5到6巴的驱动气。由此给对辊/缸同时加液压到138巴,并保持30秒钟即可。查看更多
