在机械工业中,液压传动比其它传动形式具有自己独特优点;无级变速、工作平稳、传递力强、可防过载、操纵轻便、节约动力、减轻自重、布局灵活、机构简单、节省材料、传动快捷、反应灵敏、容易实现标准化、系列化和专业化生产,易于满足各种复杂动作的自动控制需要。液压技术是近代兴起的,发展速度很快,已在机械、冶金、建筑、石油、化工、煤炭、交通、农业、纺织、饮食、卫生、轻工、航空,船舶、矿山和国防等几乎所有工业部门,作为自动化、省力化和提高效率的手段得到普遍应用。近几年来又在宇宙航行、
In the machinery industry, hydraulic transmission has its own unique advantages over other forms of transmission; continuously variable transmission, stable work, strong transmission, overload protection, light weight, power saving, self-weight reduction, flexible layout, simple mechanism, Fast, responsive, easy to standardize, serialize and professional production, easy to meet the needs of a variety of complex automatic control actions. Hydraulic technology has developed in recent years and has been developing rapidly. It has been applied in almost all industries such as machinery, metallurgy, construction, petroleum, chemicals, coal, transportation, agriculture, textiles, food, sanitation, light industry, aviation, ships, mines and national defense Department, as a means of automation, labor-saving and efficiency are widely used. In recent years, again in space navigation,
