单臂液压机在国外已成为定型系列产品,其主要系列大多数从100吨至1000吨,中间的挡数差别较大,通常为5～7个品种,有的国家也有达12个品种的。我国单臂液压机的设计、制造、使用都有一定的经验和实践,目前已生产800吨、1250吨、2500吨等品种,先后投产使用,在造船等机械工业中,发挥了很大作用。因而,在我国亦定为定型系列产品。
One-arm hydraulic press has become a stereotyped products in foreign countries, the majority of its main series from 100 tons to 1,000 tons, the difference between the larger block, usually 5 to 7 varieties, some countries have up to 12 varieties. The design, manufacture and use of single-arm hydraulic press in our country all have some experience and practice. At present, 800 tons, 1,250 tons and 2,500 tons have been produced and put into operation successively, playing a great role in the machinery industry such as shipbuilding. Therefore, in our country also set stereotypes products.
