As an object of research in this paper, we use a hydro-mechanical system of high-speed technological equipment with reciprocating movement of the output link on the example of a cyclic perforating press hammer with a force of 1600 kN and a speed of up to 75 working strokes of the slider per minute. The theoretical analysis of the operation of a high-speed hydraulic reciprocating drive for a cyclic press made using a pump-accumulator power source containing one hydraulic accumulator showed that increasing its speed is technically possible, but not economically justified. Additional calculations have shown that the loss of working fluid is actually reduced. As a result, the speed of the hydraulic reciprocating drive increases from 127 to 148 and 157 beats per minute, respectively. But at the same time, its efficiency decreases from 21% to 18% and 16%, respectively. In order to increase the speed of the hydraulic reciprocating drive, it is necessary to make fundamental changes to its scheme aimed at increasing the efficiency factor by reducing unproductive energy costs during operation.
Key words: device and operating principle / high-speed hydraulic power drive / reciprocating motion / hydromechanical system
