超高压静液传动技术在国外已得到普遍地应用,近几年在国内也有较快的发展,其主要特点是体积小,重量轻、出力大、工作平稳,并且噪声低。我们利用这些特点,研制了手提式超高压油泵,它可以做为机床夹紧,剪切、铆接、液压工具中的拉、拔、顶、压等工作的液压动力源。因为它小巧,所 Ultrahigh pressure hydrostatic transmission technology has been widely used abroad, in recent years there are rapid development in China, its main features are small size, light weight, large output, stable work, and low noise. We use these features to develop a portable ultra-high pressure pump, which can be used as a hydraulic power source for clamping, shearing, riveting, pulling, pulling, jacking and pressing in hydraulic tools. Because of its small, the
