IMPROVING THE EFFICIENCY OF HYDRAULIC DRIVES IN CYCLIC SYSTEMS

Abstract. Improving the efficiency of hydraulic drives in cyclic systems.
Purpose. To determine the advantages and disadvantages of the main methods to control hydraulic systems and the possibility of combining them.
Design/methodology/approach. It was considered the basic methods of productivity regulation of cycle action hydraulic devices and determined their advantages and disadvantages. It was detected the dependence of hydraulic system efficiency from the control methods of pumping units and their connection to the technological process of the system.
Findings. As a result it is proposed methodology for the analysis of the system in order to determine an effective method for regulating the pump unit, depending on the particular system.

Originality/value. It is found the structural division of hydraulic system units with taking into account the work modes of devices that are included in its composition.


Keywords: the regulation, the hydraulic system of cyclic operation, the pump unit, the technological process.
