美国 Mesta 公司的45000吨模锻液压机装备了新的液压控制系统,用一套电气伺服控制系统灵敏地驱动庞大的水阀。液体流量范围为:从工作压力为315公斤/厘米~2时的4.5万升/分到充液压力为10公斤/厘米~2时的10万升/分。即使在高压、大流量和2000吨的活动部分重量下,压机的动作都可精确控制。这台10层楼高的压机(6层在地面上,4层在地面下)用来制造飞机的高强度结构部件,安装在美国俄亥俄州克利夫兰工厂的铝公司,是一台专门为美国空军
The Mesta 45,000-ton forging hydraulic press in the United States is equipped with a new hydraulic control system that uses an electrical servo control system to drive a large water valve. The liquid flow rate ranges from 45,000 liters / minute at a working pressure of 315 kg / cm 2 to 100,000 liters / minute at a filling pressure of 10 kg / cm 2. Even in the high pressure, high flow and 2000 tons of active part of the weight, the press can be precisely controlled movements. The 10-story press (six on the ground and four on the ground) is a high-strength structural component used to make aircraft, installed at the Aluminum Company of the Cleveland, Ohio, plant, specifically for the U.S. Air Force
