３５０t油压机是我厂加工SS６B机车电机热压模的主要设备，压力为１５～２０MPa。一次，当热压模压到第１３个线圈时，按点动按钮升压，油压表显示１５２０MPa，松按钮后发现压力表指针立即回到０位置卸荷时间不到１s，而正常情况应是松按钮后系统自动处于保压状态。重新加压后
350t hydraulic press is our factory processing SS6B locomotive motor hot mold the main equipment, the pressure is 15 ~ 20MPa. Once, when the hot pressing mold to the 13th coil, press the jog button to boost the hydraulic gauge shows 1520MPa, loose button and found the gauge pointer immediately return to 0 position unloading time less than 1s, and the normal situation should be After the button is pressed, the system will be under pressure keeping status automatically. After repressurization
