- Abstract
High-pressure pumping units consisting of low-pressure pumping units and oscillating miniboostertype pressure intensifiers are an efficient solution for generating high pressure rates in hydraulic drive systems. Such pumping units are typically used in static applications (burst tests for pipelines and tanks) and mobile applications with high loads on small strokes of hydraulic cylinders (hydraulic tools and presses). Through experimental research, carried out on a test stand that can load a high-pressure hydraulic cylinder with heavy, high-magnitude loads, the authors demonstrated the possibility of expanding the range of technical applications of these pumping units to mobile applications with high loads over the entire stroke of hydraulic cylinders. A low-pressure pumping unit - 4 kW, 1500 rpm, 0...200 bar - was used; it was successively equipped with three types of miniboosters with different gain factors (i) (i=5.0; i=6.6; and i=7.6, respectively).
