WAYS OF ENERGY SAVING IN THE PNEUMATIC DRIVE
Brief description of performed works
Compressed air is one of the most expensive energy carriers, so the task of energy saving must be solved at all stages starting from the production of this energy carrier and its transportation to its use as a means of automating production processes.
The purpose of this work is to increase the energy efficiency of the pneumatic drive (PD) and expand the scope of application of power pneumatics in the direction of a significant increase in the inertial load due to the selection of a rational structure of switching connections for all phases of movement of the working body of the PD, as well as to determine the field of rational use of energy-saving schemes of the PD.
To achieve the goal, the following tasks were defined and solved:
– justification of the most rational structure of switching connections for all phases of movement of the working body of the PD, which ensure the minimization of unproductive energy consumption;
– development of an energy-saving PD scheme and its management algorithm;
– computer modeling based on the developed mathematical model in dimensional and dimensionless form in order to determine the field of rational use of the energy-saving PD scheme.
