MINIMIZING ENVIRONMENTAL DAMAGE FROM VIBRATION MACHINES
It is shown that during the operation of vibration machines, a significant mechanical reactive power develops, due to the mass of the working bodies. Mechanical reactive power is transformed into reactive electrical power, the flows of which in the supply network generate significant heat losses in the wires. As a result, there is environmental damage due to the dissipation of heat into the atmosphere. In many vibration machines with two massive working bodies, the phases of their oscillations are shifted by half the oscillation period. Obviously, the resulting power is equal to twice the reactive power of each working body. To compensate for reactive mechanical power, the oscillation phases of massive working bodies should be shifted by a quarter of the oscillation period. In this case, the resulting power is zero. This means that the braking energy of one massive working body is spent on accelerating another, and is not transferred to the drive and further into the network. Thus, the energy of the supply network is spent only on compensation for friction losses and on the actual technological process, which leads to minimization of environmental damage from vibration machines
