一、概况近年来,液压机发展的主要特征之一是广泛采用泵直接传动。与水泵——蓄势站传动的液压机相比较,这种传动具有设备简单、重量轻、投资少、生产效率和自动化程度高等优点。文化大革命以来,各厂矿在工业学大庆的运动中大干快上了许多液压机,其中多数是采用直接传动的。这对在重型锻压机械中大搞群众运动,大中小厂相结合和落实毛主席“自力更生”的指示,高速度发展我国液压机设备展示了广阔的前景。
First, an overview In recent years, one of the main features of hydraulic machine development is the widespread use of pump direct drive. This pump has the advantages of simple equipment, light weight, less investment, higher production efficiency and higher degree of automation than the hydraulic pump of the pump-poise. Since the Cultural Revolution, various factories and mines have drastically put up many hydraulic machines in the Daqing industrial movement, most of which use direct transmission. This shows a broad prospect of developing the hydraulic machine equipment at a high speed in the direction of carrying out mass movements, large, small and medium-sized factories in heavy forging machinery and implementing Chairman Mao’s “self-reliance.”
